Notes To Financial Statements [Abstract]
SHAREHOLDER’S EQUITY	SHAREHOLDERS' EQUITY OF MAA On December 31, 2015 , 75,408,571 shares of common stock of MAA and 4,162,996 partnership units in the Operating Partnership were issued and outstanding, representing a total of 79,571,567 shares and units. At December 31, 2014 , 75,267,675 shares of common stock of MAA and 4,191,152 partnership units in the Operating Partnership were outstanding, representing a total of 79,458,827 shares and units. There were 58,112 outstanding options as of December 31, 2015 compared to 74,454 outstanding options as of December 31, 2014 . During the year ended December 31, 2015 , 11,914 shares of our common stock were acquired from employees to satisfy minimum tax withholding obligations that arose upon vesting of restricted stock granted pursuant to approved plans. During the year ended December 31, 2014 , 9,270 shares were acquired for these purposes. Noncontrolling Interest Noncontrolling interest in the accompanying Consolidated Financial Statements relates to the limited partnership interest in the Operating Partnership owned by the holders of the Class A limited partner units of the Operating Partnership, or Class A Units. MAA is the sole general partner of the Operating Partnership and holds all of the outstanding Class B general partner units of the Operating Partnership, or Class B Units. Net income is allocated to MAA and the noncontrolling interest based on their respective ownership percentages of the Operating Partnership. Issuance of additional Class A Units or Class B Units changes the ownership percentage of both the noncontrolling interest and MAA. The issuance of Class B Units generally occurs when MAA issues common stock and the issuance proceeds are contributed to the Operating Partnership in exchange for Class B Units equal to the number of shares of common stock issued. At each reporting period, the allocation between total MAA shareholders’ equity and Noncontrolling interest is adjusted to account for the change in the respective percentage ownership of the underlying equity of the Operating Partnership. MAA’s Board of Directors established economic rights in respect to each Class A Unit that were equivalent to the economic rights in respect to each share of MAA common stock. The holders of Class A Units may redeem each of their units in exchange for one share of common stock in MAA or cash, at the option of MAA. At December 31, 2015 , a total of 4,162,996 Class A Units were outstanding and redeemable to MAA by the holders of the units for 4,162,996 shares of MAA common stock or approximately $378.0 million , based on the closing price of MAA’s common stock on December 31, 2015 of $90.81 per share, at MAA’s option. At December 31, 2014 , a total of 4,191,152 Class A Units were outstanding and redeemable to MAA by the holders of the units for 4,191,152 shares of MAA common stock or approximately $313.0 million , based on the closing price of MAA’s common stock on December 31, 2014 of $74.68 per share, at MAA’s option. The Operating Partnership pays the same per unit distribution in respect to the Class A Units as the per share distribution MAA pays in respect to the common stock. Operating Partnership net income for 2015 , 2014 and 2013 was allocated approximately 5.2% , 5.3% and 4.6% , respectively, to holders of Class A Units and 94.8% , 94.7% and 95.4% , respectively, to MAA as the holder of all Class B Units. Direct Stock Purchase and Distribution Reinvestment Plan MAA has a Dividend and Distribution Reinvestment and Share Purchase Plan, or DRSPP, pursuant to which MAA’s shareholders have the ability to reinvest all or part of their distributions from MAA’s stock and holders of Class A Units have the ability to reinvest all or part of their distributions from MAALP into MAA’s common stock. The DRSPP also provides the opportunity to make optional cash investments in MAA's common stock of at least $250 , but not more than $5,000 in any given month, free of brokerage commissions and charges. MAA, in its absolute discretion, may grant waivers to allow for optional cash payments in excess of $5,000 . To fulfill its obligations under the DRSPP, MAA may either issue additional shares of common stock or repurchase common stock in the open market. MAA has registered with the SEC the offer and sale of up to 9,600,000 shares of common stock pursuant to the DRSPP. MAA may elect to sell shares under the DRSPP at up to a 5% discount. Shares of common stock totaling 8,562 in 2015 , 9,055 in 2014 , and 10,924 in 2013 were acquired by shareholders under the DRSPP. MAA did not offer a discount for optional cash purchases in 2015 , 2014 or 2013 . At the Market Offering On December 9, 2015, we entered into distribution agreements with J.P. Morgan Securities, LLC, BMO Capital Markets Corp. and KeyBanc Capital Markets Inc. to sell up to an aggregate of 4.0 million shares of common stock, from time-to-time in at-the-market offerings or negotiated transactions through controlled equity offering programs, or ATMs. As of December 31, 2015 , there were 4.0 million shares remaining under the ATM program. During the years ended December 31, 2015 and 2014 , MAA did not sell any shares of common stock under its ATMs. As of December 31, 2015, there were 4.0 million shares available for issuance under MAA's ATMs. Stock Repurchase Plan In 1999, MAA’s Board of Directors approved a stock repurchase plan to acquire up to a total of 4.0 million shares of MAA’s common stock. As of December 8, 2015, MAA had repurchased and retired approximately 1.9 million shares of common stock for a cost of approximately $42.0 million at an average price per common share of $22.54 . No shares were repurchased in 2002 through 2015 under the plan. On December 8, 2015, MAA's Board of Directors authorized us to repurchase up to 4.0 million shares of MAA common stock, which represented approximately 5.3% of MAA's common stock outstanding at the time of such authorization. This December 2015 authorization replaced and superseded the 1999 plan, under which approximately 2.1 million shares remained at the time of the December 2015 authorization. No shares were repurchased from December 8, 2015 through December 31, 2015 under the current authorization. Exercise of Stock Options During the years ended December 31, 2015 , 2014 , and 2013 we issued 7,342 shares, 270,459 shares, and 110,715 shares, respectively, related to the exercise of stock options. These exercises resulted in proceeds of $0.4 million , $12.2 million , and $6.2 million respectively.

Unless the context otherwise requires, the references to the “Operating Partnership” or “MAALP” refer to Mid-America Apartments, L.P. together with its consolidated subsidiaries. “Common stock” refers to the common stock of MAA and “shareholders” means the holders of shares of MAA’s common stock. The limited partnership interests of the Operating Partnership are referred to as “OP Units” or "common units" and the holders of the OP Units are referred to as “unitholders”. As of December 31, 2015 , MAA owned 75,408,571 units (or approximately 94.8% ) of the limited partnership interests of the Operating Partnership. MAA conducts substantially all of its business and holds substantially all of its assets through the Operating Partnership, and by virtue of its ownership of the OP Units and being the Operating Partnership's sole general partner, MAA has the ability to control all of the day-to-day operations of the Operating Partnership. We believe combining the notes to the consolidated financial statements of MAA and MAALP results in the following benefits: • enhances a readers' understanding of MAA and the Operating Partnership by enabling the reader to view the business as a whole in the same manner that management views and operates the business; • eliminates duplicative disclosure and provides a more streamlined and readable presentation since a substantial portion of the disclosure applies to both MAA and the Operating Partnership. Management operates MAA and the Operating Partnership as one business. The management of the Company is comprised of individuals who are officers of MAA and employees of the Operating Partnership. We believe it is important to understand the few differences between MAA and the Operating Partnership in the context of how MAA and the Operating Partnership operate as a consolidated company. MAA and the Operating Partnership are structured as an "umbrella partnership REIT," or UPREIT. MAA's interest in the Operating Partnership entitles MAA to share in cash distributions from, and in the profits and losses of, the Operating Partnership in proportion to MAA's percentage interest therein and entitles MAA to vote on substantially all matters requiring a vote of the partners. MAA's only material asset is its ownership of limited partner interests in the Operating Partnership; therefore, MAA does not conduct business itself, other than acting as the sole general partner of the Operating Partnership, issuing public equity from time to time and guaranteeing certain debt of the Operating Partnership. The Operating Partnership holds, directly or indirectly, all of our real estate assets. Except for net proceeds from public equity issuances by MAA, which are contributed to the Operating Partnership in exchange for OP Units, the Operating Partnership generates the capital required by our business through the Operating Partnership's operations, direct or indirect incurrence of indebtedness and issuance of OP units. The presentation of MAA's shareholders' equity and the Operating Partnership's capital are the principal areas of difference between the consolidated financial statements of MAA and those of the Operating Partnership. MAA's shareholders' equity may include shares of preferred stock, shares of common stock, additional paid-in capital, cumulative earnings, cumulative distributions, noncontrolling interest, preferred units, treasury shares, accumulated other comprehensive income and redeemable common units. The Operating Partnership's capital may include common capital and preferred capital of the general partner (MAA), limited partners' preferred capital, limited partners' noncontrolling interest, accumulated other comprehensive income and redeemable common units. Redeemable common units represent the number of outstanding OP Units as of the date of the applicable balance sheet, valued at the greater of the closing market price of MAA's common stock or the aggregate value of the individual partners' capital balances. Holders of OP Units (other than MAA and its corporate affiliates) may require us to redeem their OP Units from time to time, in which case we may, at our option, pay the redemption price either in cash (in an amount per OP Unit equal, in general, to the average closing price of MAA's common stock on the New York Stock Exchange over a specified period prior to the redemption date) or by delivering one share of our common stock (subject to adjustment under specified circumstances) for each OP Unit so redeemed. Organization and Formation of Mid-America Apartment Communities, Inc. On October 1, 2013, MAA completed a merger with Colonial Properties Trust, or Colonial. Pursuant to the merger agreement, Martha Merger Sub, LP, or OP Merger Sub, a wholly-owned indirect subsidiary of MAALP, merged with and into Colonial Realty Limited Partnership, or Colonial LP, with Colonial LP being the surviving entity of the merger and becoming a wholly-owned indirect subsidiary of MAALP, which is referred to as the partnership merger. The partnership merger was part of the transactions contemplated by the agreement and plan of merger entered into on June 3, 2013 among MAA, our Operating Partnership, OP Merger Sub, Colonial, and Colonial LP pursuant to which MAA and Colonial combined through a merger of Colonial with and into MAA, with MAA surviving the merger, which is referred to as the parent merger. We refer to the parent merger, together with the partnership merger, as the "Merger". Under the terms of the merger agreement, each Colonial common share was converted into the right to receive 0.36 of a newly issued share of MAA common stock. In addition, each limited partner interest in Colonial LP designated as a “Class A Unit” and a “Partnership Unit” under the limited partnership agreement of Colonial LP, which we refer to in this filing as Colonial LP units, issued and outstanding immediately prior to the effectiveness of the partnership merger was converted into common units in MAALP at the 0.36 conversion rate. The net assets and results of operations of Colonial are included in our consolidated financial statements from the closing date, October 1, 2013, going forward. See further discussion surrounding the Merger in Note 2 (Business Combinations) below. As of December 31, 2015, we owned and operated 254 apartment communities through the Operating Partnership. As of December 31, 2015 , MAA also owned a 25.00% interest in an unconsolidated real estate joint venture consisting of undeveloped land and a 33.30% interest in an unconsolidated real estate joint venture consisting of one commercial property. As of December 31, 2015 , we had five development communities under construction totaling 748 units, with 37 units completed. Total expected costs for the development projects are $116.6 million , of which $42.3 million had been incurred to date. We expect to complete construction on one project by the first quarter of 2016, one project by the third quarter of 2016, two projects by the second quarter of 2017, and one project by the fourth quarter of 2017. Five of our multifamily properties include retail components with approximately 163,000 square feet of gross leasable area. We also have one wholly owned commercial property, which we acquired through the Merger, with approximately 208,000 square feet of gross leasable area, excluding tenant owned anchor stores, and one unconsolidated commercial property with approximately 30,000 square feet of gross leasable area. Reclassifications To provide a better presentation of operating expenses, we adjusted the presentation of certain expenses in the specified lines of the Consolidated Statements of Operations. In our Annual Report on Form 10-K for the fiscal year ended December 31, 2014, our 2014 Form 10-K, we reported approximately $1.3 million and $0.8 million in permits and fees and vehicle maintenance costs in the "Other operating" expense line for the twelve months ended December 31, 2014 and December 31, 2013, respectively. These costs have been reclassified to "Building repairs and maintenance" for the twelve months ended December 31, 2014 and December 31, 2013, respectively, presented in the Consolidated Statement of Operations included in this Annual Report on Form 10-K for the fiscal year ended December 31, 2015, or this Form 10-K. In the 2014 Form 10-K, we also reported approximately $33.8 million and $17.6 million in utility costs, primarily for cable TV, trash removal, and telephone costs, in the "Other operating" expense line for the twelve months ended December 31, 2014 and December 31, 2013, respectively. These costs have been reclassified to "Utilities" for the twelve months ended December 31, 2014 and December 31, 2013, respectively, presented in the Consolidated Statement of Operations included in this Form 10-K. These changes have been made in order to provide better insight into how we manage our property operating expenses. In the 2014 Form 10-K, we reported approximately $36.5 million as "Assets held for sale, excluded from Real estate assets, net", which included $1.3 million of Cash and cash equivalents. These assets no longer qualify as held for sale and have been reclassified to Assets held for use within the applicable line items in the Consolidated Balance Sheet and Consolidated Statements of Cash Flows included in this Form 10-K. See further discussion on the held for sale reclassification in Note 15 (Earnings from Discontinued Operations) below. In April 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. ASU 2015-03 requires debt issuance costs to be presented in the balance sheet as a reduction of the related debt liability rather than an asset. The update requires retrospective application and represents a change in accounting principle. We early-adopted ASU 2015-03 as of the end of fiscal year 2015, and applied its provisions retrospectively. The adoption of ASU 2015-03 resulted in the reclassification of $13.3 million and $11.8 million of unamortized debt issuance costs related to our secured property mortgages, senior unsecured notes, and unsecured term loans from "Deferred financing costs, net" to a reduction in "Unsecured notes payable", of $11.7 million and $9.3 million , and "Secured notes payable", of $1.6 million and $2.5 million , within our Consolidated Balance Sheets as of December 31, 2015 and 2014, respectively. In the 2014 Form 10-K, we reported approximately $4.5 million and $3.1 million of "Amortization of deferred financing costs" for the years ended December 31, 2014 and 2013, respectively. As a result of the adoption of the debt issuance cost guidance and to improve comparability, we also reclassified these costs to "Interest expense" for the twelve months ended December 31, 2014 and 2013, respectively, presented in the Consolidated Statement of Operations included in this Form 10-K. As a result of this income statement reclassification, $4.5 million and $3.1 million of amortization of deferred financing costs for the years ended December 31, 2014 and 2013, respectively, reported in the "Depreciation and amortization" line of the Consolidated Statements of Cash Flows in the 2014 Form 10-K have been reclassified to "Amortization of debt premium and debt issuance costs" for the twelve months ended December 31, 2014 and 2013, respectively, presented in the Consolidated Statements of Cash Flows in this Form 10-K. Other than these reclassifications, the adoption of ASU 2015-03 did not have an impact on our consolidated financial statements. See Note 6 (Borrowings) below for further discussion. Basis of Presentation and Principles of Consolidation The accompanying consolidated financial statements have been prepared by our management in accordance with United States generally accepted accounting principles, or GAAP, and applicable rules and regulations of the Securities and Exchange Commission, or the SEC. The consolidated financial statements of MAA presented herein include the accounts of MAA, the Operating Partnership, and all other subsidiaries in which MAA has a controlling financial interest. MAA owns approximately 95% to 100% of all consolidated subsidiaries. The consolidated financial statements of MAALP presented herein include the accounts of MAALP and all other subsidiaries in which MAALP has a controlling financial interest. MAALP owns, directly or indirectly, 100% of all consolidated subsidiaries. In our opinion, all adjustments necessary for a fair presentation of the consolidated financial statements have been included, and all such adjustments were of a normal recurring nature. All significant intercompany accounts and transactions have been eliminated in consolidation. We invest in entities which may qualify as variable interest entities, or VIE. A VIE is a legal entity in which the equity investors lack sufficient equity at risk for the entity to finance its activities without additional subordinated financial support or, as a group, the holders of the equity investment at risk lack the power to direct the activities of a legal entity as well as the obligation to absorb its expected losses or the right to receive its expected residual returns. We consolidate all VIEs for which we are the primary beneficiary and use the equity method to account for investments that qualify as VIEs but for which we are not the primary beneficiary. In determining whether we are the primary beneficiary of a VIE, we consider qualitative and quantitative factors, including but not limited to, those activities that most significantly impact the VIE's economic performance and which party controls such activities. We use the equity method of accounting for our investments in entities for which we exercise significant influence, but do not have the ability to exercise control. These entities are not variable interest entities. The factors considered in determining that we do not have the ability to exercise control include ownership of voting interests and participatory rights of investors. Use of Estimates Management has made a number of estimates and assumptions relating to the reporting of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of revenues and expenses to prepare these financial statements and notes in conformity with GAAP. Actual results could differ from those estimates. Revenue Recognition and Real Estate Sales We primarily lease multifamily residential apartments under operating leases generally with terms of one year or less. Rental revenues are recognized using a method that represents a straight-line basis over the term of the lease and other revenues are recorded when earned. Rental income represents gross market rent less adjustments for concessions, vacancy loss and bad debt. We record gains and losses on real estate sales in accordance with accounting standards governing the sale of real estate. For sale transactions meeting the requirements for the full accrual method, we remove the assets and liabilities from our Consolidated Balance Sheets and record the gain or loss in the period the transaction closes. Rental Costs Costs associated with rental activities, including advertising costs, are expensed as incurred. Advertising expenses were approximately $13.5 million , $12.4 million , and $9.5 million for the years ended December 31, 2015 , 2014 , and 2013 , respectively. Discontinued Operations Prior to our January 2014 adoption of ASU No. 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity, properties sold during the year or those classified as held-for-sale at the end of a reporting period were classified as discontinued operations in accordance with accounting standards governing financial statement presentation. Subsequent to our adoption of this ASU on January 1, 2014, only dispositions representing significant changes in operating strategy are classified as discontinued operations. Once a property is classified as held-for-sale, depreciation is no longer recognized. Real Estate Assets and Depreciation and Amortization Real estate assets are carried at depreciated cost. Repairs and maintenance costs are expensed as incurred while significant improvements, renovations, and recurring capital replacements are capitalized. Recurring capital replacements typically include scheduled carpet replacement, new roofs, HVAC units, plumbing, concrete, masonry and other paving, pools and various exterior building improvements. In addition to these costs, we also capitalize salary costs directly identifiable with renovation work. These expenditures extend the useful life of the property and increase the property’s fair market value. The cost of interior painting, vinyl flooring and blinds are expensed as incurred. Depreciation is computed on a straight-line basis over the estimated useful lives of the related assets which range from 8 to 40 years for land improvements and buildings, 5 years for furniture, fixtures and equipment, and 3 to 5 years for computers and software. Development Costs Development projects and the related carrying costs, including interest, property taxes, insurance and allocated direct development salary cost during the construction period, are capitalized and reported in the accompanying Consolidated Balance Sheets as “Development and capital improvements in progress” during the construction period. Interest is capitalized in accordance with accounting standards governing the capitalization of interest. Upon completion and certification for occupancy of individual buildings within a development, amounts representing the completed building's portion of total estimated development costs for the project are transferred to "Land", "Buildings", and "Furniture, fixtures and equipment" as real estate held for investment. Capitalization of interest, property taxes, insurance and allocated direct development salary costs cease upon the transfer. The assets are depreciated over their estimated useful lives. Total interest capitalized during the years ended December 31, 2015 , 2014 and 2013 was approximately $1.7 million , $1.7 million , and $2.1 million , respectively. Indirect costs other than interest that we capitalized included capitalized salaries of $0.4 million , $1.7 million , and $0.4 million during the years ended December 31, 2015 , 2014 and 2013 , respectively, and real estate taxes of $0.2 million , $0.2 million , and $0.3 million during the years ended December 31, 2015 , 2014 and 2013 , respectively. Certain costs associated with the lease-up of development projects, including cost of model units, their furnishings, signs, and “grand openings,” are capitalized and amortized over their respective estimated useful lives. All other costs relating to renting development projects are expensed as incurred. Acquisition of Real Estate Assets In accordance with accounting standards for business combinations, the fair value of the real estate acquired is allocated to the acquired tangible assets, consisting of land, building, furniture, fixtures and equipment, and identified intangible assets, consisting of the value of in-place leases and other contracts. We allocate the purchase price to the fair value of the tangible assets of an acquired property determined by valuing the building as if it were vacant, based on management’s determination of the relative fair values of these assets. Management determines the as-if-vacant fair value of a building using methods similar to those used by independent appraisers. These methods include using stabilized net operating income, or NOI, and market specific capitalization and discount rates. In allocating the fair value of identified intangible assets of an acquired property, the in-place leases are valued based on current rent rates and time and cost to lease a unit. Management concluded that the residential leases acquired in connection with each of its property acquisitions are approximately at market rates since the residential lease terms generally do not extend beyond one year. For larger, portfolio style acquisitions, like the Merger, management engages a third party valuation specialist to perform the fair value assessment, which includes an allocation of the purchase price. Similar to management's methods, the third party uses cash flow analysis as well as an income approach and a market approach to determine the fair value of assets. The third party uses stabilized NOI and market specific capitalization and discount rates. Management reviews the inputs used by the third party specialist as well as the allocation of the purchase price provided by the third party to ensure reasonableness and that the procedures are performed in accordance with management's policy. The initial allocation of the purchase price is based on management’s preliminary assessment, which may differ when final information becomes available. Subsequent adjustments made to the initial purchase price allocation, if any, are made within the allocation period, which typically does not exceed one year. For residential leases, the fair value of the in-place leases and resident relationships is then amortized over 6 months, the estimated remaining term of the resident leases. For commercial leases, the fair value of in-place leases and resident relationships is amortized over the remaining term of the commercial leases. The amount of lease intangibles included in Other assets totaled $6.1 million , $8.3 million , and $54.0 million as of December 31, 2015 , 2014 , and 2013 , respectively. Accumulated amortization for these leases totaled $2.3 million , $1.8 million , and $21.9 million as of December 31, 2015 , 2014 and 2013 , respectively. The amortization recorded as depreciation and amortization expense was $5.0 million , $24.5 million , and $23.5 million for the years ended December 31, 2015 , 2014 , and 2013 , respectively. The estimated aggregate future amortization expense is approximately $1.4 million , $0.5 million , $0.4 million , $0.3 million , and $0.3 million for the years ended December 31, 2016, 2017, 2018, 2019, and 2020, respectively. The Company's policy is to expense the costs incurred to acquire properties in the period these costs are incurred. Acquisition costs include appraisal fees, title fees, broker fees, and other legal costs to acquire the property. These costs are recorded in our Consolidated Statement of Operations under the line "Acquisition expenses". Impairment of Long-lived Assets, including Goodwill We account for long-lived assets in accordance with the provisions of accounting standards for the impairment or disposal of long-lived assets and evaluate our goodwill for impairment under accounting standards for goodwill and other intangible assets. We evaluate goodwill for impairment on at least an annual basis, or more frequently if a goodwill impairment indicator is identified. We periodically evaluate long-lived assets, including investments in real estate and goodwill, for indicators that would suggest that the carrying amount of the assets may not be recoverable. The judgments regarding the existence of such indicators are based on factors such as operating performance, market conditions and legal factors. Long-lived assets, such as real estate assets, equipment and purchased intangibles subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized for the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of are separately presented on the Balance Sheet and reported at the lower of the carrying amount or fair value less costs to sell, and are no longer depreciated. The assets and liabilities of a disposed group or a property classified as held for sale are presented separately in the appropriate asset and liability sections of the balance sheet. Goodwill is tested annually for impairment and is tested for impairment more frequently if events and circumstances indicate that the asset might be impaired. An impairment loss for goodwill is recognized to the extent that the carrying amount exceeds the implied fair value of goodwill. This determination is made at the reporting unit level and consists of two steps. First, we determine the fair value of a reporting unit and compare it to its carrying amount. In the apartment industry, the primary method used for determining fair value is to divide annual operating cash flows by an appropriate capitalization rate. We determine the appropriate capitalization rate by reviewing the prevailing rates in a property’s market or submarket. Second, if the carrying amount of a reporting unit exceeds its fair value, an impairment loss is recognized for any excess of the carrying amount of the reporting unit’s goodwill over the implied fair value of that goodwill. The implied fair value of goodwill is determined by allocating the fair value of the reporting unit in a manner similar to a purchase price allocation in accordance with accounting standards for business combinations. The residual fair value after this allocation is the implied fair value of the reporting unit goodwill. There has been no impairment of goodwill in the three year period ended December 31, 2015 . Goodwill decreased from $2.3 million at December 31, 2014 to $1.6 million at December 31, 2015 as a result of the disposition of the Post House Jackson, Post House North, and Oaks apartment communities on April 29, 2015. Goodwill decreased from $4.1 million at December 31, 2013 to $2.3 million at December 31, 2014 as a result of the disposition of the Greenbrook apartment community on July 10, 2014. Loss Contingencies The outcomes of claims, disputes and legal proceedings are subject to significant uncertainty. We record an accrual for loss contingencies when a loss is probable and the amount of the loss can be reasonably estimated. We review these accruals quarterly and make revisions based on changes in facts and circumstances. When a loss contingency is not both probable and reasonably estimable, we do not accrue the loss. However, if the loss (or an additional loss in excess of the accrual) is at least a reasonable possibility and material, then we disclose a reasonable estimate of the possible loss, or range of loss, if such reasonable estimate can be made. If we cannot make a reasonable estimate of the possible loss, or range of loss, then a statement to that effect is disclosed. The assessment of whether a loss is probable or a reasonable possibility, and whether the loss or range of loss is reasonably estimable, often involves a series of complex judgments about future events. Among the factors that we consider in this assessment, are the nature of existing legal proceedings and claims, the asserted or possible damages or loss contingency (if reasonably estimable), the progress of the matter, existing law and precedent, the opinions or views of legal counsel and other advisers, our experience in similar matters, the facts available to us at the time of assessment, and how we intend to respond, or have responded, to the proceeding or claim. Our assessment of these factors may change over time as individual proceedings or claims progress. For matters where we are not currently able to reasonably estimate a range of reasonably possible loss, the factors that have contributed to this determination include the following: (i) the damages sought are indeterminate; (ii) the proceedings are in the early stages; (iii) the matters involve novel or unsettled legal theories or a large or uncertain number of actual or potential cases or parties; and/or (iv) discussions with the parties in matters that are expected ultimately to be resolved through negotiation and settlement have not reached the point where we believe a reasonable estimate of loss, or range of loss, can be made. In such instances, we believe that there is considerable uncertainty regarding the timing or ultimate resolution of such matters, including a possible eventual loss or business impact, if any. Undeveloped Land Undeveloped land includes sites intended for future multifamily developments, sites for future commercial development and sites intended for residential use, which are carried at the lower of cost or fair value in accordance with GAAP and any costs incurred prior to commencement of pre-development activities are expensed as incurred. Investment in Real Estate Joint Ventures Our investments in our unconsolidated real estate joint ventures are recorded using the equity method as we are able to exert significant influence, but do not have a controlling interest in any of our joint ventures. Cash and Cash Equivalents We consider investments in money market accounts and certificates of deposit with original maturities of three months or less to be cash equivalents. Restricted Cash Restricted cash consists of security deposits required to be held separately, escrow deposits held by lenders for property taxes, insurance, debt service, and replacement reserves, and exchanges under Section 1031(b) of the Internal Revenue Code of 1986, as amended, or the Code. Section 1031(b) exchanges are treated as investing activities in the Consolidated Statement of Cash Flows. Deferred Financing Costs Deferred financing costs are amortized over the terms of the related debt using a method which approximates the effective interest method. If the terms of renewed or modified debt instruments are deemed to be substantially different, all unamortized financing costs associated with the modified debt are charged to earnings in the current period. If the terms are not substantially different, the costs associated with the renewal are capitalized and amortized over the remaining term of the debt instrument. For modifications affecting a line of credit, fees paid to a creditor and any third party costs will be capitalized and amortized over the remaining term of the new arrangement. Any unamortized deferred financing costs associated with the old arrangement are either deferred and amortized over the life of the new arrangement or written off, depending upon the nature of the modification and cost. The balance of any unamortized financing costs on extinguished debt is expensed upon extinguishment. Other Assets Other assets consist primarily of deferred rental concessions which are recognized on a straight line basis over the life of the leases, receivables and deposits from residents, the value of derivative contracts and other prepaid expenses including prepaid insurance and prepaid interest. Also included in other assets are the fair market value of in place leases, which totaled $6.1 million and $8.3 million as of December 31, 2015 and 2014 , respectively. Accrued Expenses and Other Liabilities Accrued expenses consist of accrued dividends payable, accrued real estate taxes, accrued interest payable, other accrued expenses payable, and unearned income. Significant accruals include accrued dividends payable of $65.2 million and $61.2 million at December 31, 2015 and 2014 , respectively, accrued real estate taxes of $63.3 million and $56.8 million at December 31, 2015 and 2014 , respectively, and accrued interest payable of $17.2 million and $17.8 million , at December 31, 2015 and 2014 , respectively. Self-Insurance We are self-insured for workers' compensation claims up to $500,000 and for general liability claims up to $100,000 . Claims exceeding these amounts are insured by a third party. We accrue for expected liabilities less than $500,000 for workers' compensation based on a third party actuarial estimate of ultimate losses and we

Business Combinations [Abstract]
BUSINESS COMBINATIONS	BUSINESS COMBINATIONS Merger of MAA and Colonial On October 1, 2013, we completed the Merger with Colonial and Colonial LP. As part of the Merger, we acquired 115 wholly owned apartment communities encompassing 34,370 units principally located in the Southeast and Southwest regions of the United States. In addition to the apartment communities, we also acquired four commercial properties totaling approximately 806,000 square feet. The additions caused us to nearly double in size as a result of the Merger. The consolidated net assets and results of operations of Colonial are included in our consolidated financial statements from the closing date, October 1, 2013, going forward. The total purchase price of approximately $2.2 billion was determined based on the number of Colonial shares and Colonial LP partnership interests outstanding as of October 1, 2013. In all cases in which MAA’s stock price was a determining factor in arriving at final consideration for the Merger, the stock price used to determine the purchase price was the opening price of MAA’s common stock on October 1, 2013 ( $62.56 per share). The total purchase price includes $7.3 million of other consideration, a majority of which relates to assumed stock compensation plans. As a result of the Merger, we issued approximately 31.9 million shares of MAA common stock and approximately 2.6 million OP units. The Merger has been accounted for using the acquisition method of accounting in accordance with ASC 805, Business Combinations , which requires, among other things, that the assets acquired and liabilities assumed be recognized at their acquisition date fair values. For larger, portfolio style acquisitions, like the Merger, management engages a third party valuation specialist to assist with the fair value assessment, which includes an allocation of the purchase price. Similar to management's methods, the third party generally uses cash flow analysis as well as an income approach and a market approach to determine the fair value of assets acquired. The third party uses stabilized NOI and a market specific capitalization and discount rates. Management reviews the inputs used by the third party specialist as well as the allocation of the purchase price provided by the third party to ensure reasonableness and that the procedures are performed in accordance with management's policy. The allocation of the purchase price is based on management’s assessment, which may differ as more information becomes available. Subsequent adjustments made to the purchase price allocation, if any, are made within the allocation period, which typically does not exceed one year. The allocation of the purchase price described above requires a significant amount of judgment and represents management's best estimate of the fair value as of the acquisition date . The following final purchase price allocation was based on our valuation as well as estimates and assumptions of the acquisition date fair value of the tangible and intangible assets acquired and liabilities assumed. The following table summarizes the final purchase price allocation (in thousands): Land $ 469,396 Buildings and improvements 3,080,858 Furniture, fixtures and equipment 96,377 Development and capital improvements in progress 113,368 Undeveloped land 58,400 Properties held for sale 33,300 Lease intangible assets 57,946 Cash and cash equivalents 63,454 Restricted cash 6,825 Deferred costs and other assets, excluding lease intangible assets 86,141 Total assets acquired 4,066,065 Notes payable (1,759,550) Fair market value of interest rate swaps (14,961) Accounts payable, accrued expenses, and other liabilities (128,678) Total liabilities assumed, including debt (1,903,189 ) Total purchase price $ 2,162,876 We incurred total merger and integration related expenses of $11.5 million and $37.5 million for the years ended December 31, 2014 and 2013, respectively. These amounts were expensed as incurred and are included in the Consolidated Statement of Operations in the items titled "Merger related expenses", primarily consisting of severance, legal, and professional costs, and "Integration related expenses", primarily consisting of temporary systems, staffing, and facilities costs. The allocation of fair values of the assets acquired and liabilities assumed has not changed from the allocation reported in Item 8.

Earnings per share	EARNINGS PER COMMON SHARE OF MAA Basic earnings per share is computed by dividing net income available to MAA common shareholders by the weighted average number of shares outstanding during the period. All outstanding unvested restricted share awards contain rights to non-forfeitable dividends and participate in undistributed earnings with common shareholders and, accordingly, are considered participating securities that are included in the two-class method of computing basic earnings per share. Both the unvested restricted shares and other potentially dilutive common shares, and the related impact to earnings, are considered when calculating earnings per share on a diluted basis with our diluted earnings per share being the more dilutive of the treasury stock or two-class methods. Operating partnership units are included in dilutive earnings per share calculations when they are dilutive to earnings per share. For the years ended December 31, 2015 , 2014 , and 2013 , MAA's basic earnings per share is computed using the two-class method, and our diluted earnings per share is computed using the more dilutive of the treasury stock method or two-class method: (dollars and shares in thousands, except per share amounts) Years ended December 31, 2015 2014 2013 Shares Outstanding Weighted average common shares - basic 75,176 74,982 50,677 Weighted average partnership units outstanding — (1) — (1) 2,351 Effect of dilutive securities — (2) — (2) 88 Weighted average common shares - diluted 75,176 74,982 53,116 Calculation of Earnings per Share - basic Income from continuing operations $ 350,745 $ 150,946 $ 37,692 Income from continuing operations attributable to noncontrolling interests (18,458 ) (8,013 ) (1,154 ) Income from continuing operations allocated to unvested restricted shares (772 ) (278 ) (34 ) Income from continuing operations available for common shareholders, adjusted $ 331,515 $ 142,655 $ 36,504 Income from discontinued operations $ — $ 5,331 $ 81,587 Income from discontinued operations attributable to noncontrolling interest — (284 ) (2,845 ) Income from discontinued operations allocated to unvested restricted shares — (10 ) (73 ) Income from discontinued operations available for common shareholders, adjusted $ — $ 5,037 $ 78,669 Weighted average common shares - basic 75,176 74,982 50,677 Earnings per share - basic $ 4.41 $ 1.97 $ 2.27 Calculation of Earnings per Share - diluted Income from continuing operations $ 350,745 $ 150,946 $ 37,692 Income from continuing operations attributable to noncontrolling interests (18,458 ) (1) (8,013 ) (1) — Income from continuing operations allocated to unvested restricted shares (772 ) (2) (278 ) (2) — Income from continuing operations available for common shareholders, adjusted $ 331,515 $ 142,655 $ 37,692 Income from discontinued operations $ — $ 5,331 $ 81,587 Income from discontinued operations attributable to noncontrolling interest — (1) (284 ) (1) — Income from discontinued operations allocated to unvested restricted shares — (2) (10 ) (2) — Income from discontinued operations available for common shareholders, adjusted $ — $ 5,037 $ 81,587 Weighted average common shares - diluted 75,176 74,982 53,116 Earnings per share - diluted $ 4.41 $ 1.97 $ 2.25 (1) For both the years ended December 31, 2015 and 2014, 4.2 million OP units and their related income are not included in the diluted earnings per share calculations as they are not dilutive.

Earnings per unit of MAA LP [Abstract]
Earnings per OP Unit	EARNINGS PER OP UNIT OF MAALP Basic earnings per OP Unit is computed by dividing net income available for common unitholders by the weighted average number of units outstanding during the period. All outstanding unvested restricted unit awards contain rights to non-forfeitable distributions and participate in undistributed earnings with common unitholders and, accordingly, are considered participating securities that are included in the two-class method of computing basic earnings per OP unit. Diluted earnings per OP Unit reflects the potential dilution that could occur if securities or other contracts to issue OP Units were exercised or converted into OP Units. A reconciliation of the numerators and denominators of the basic and diluted earnings per OP unit computations for the years ended December 31, 2015 , 2014 , and 2013 is presented below: (dollars and units in thousands, except per unit amounts) Years ended December 31, 2015 2014 2013 Units Outstanding Weighted average common units - basic 79,361 79,188 53,075 Effect of dilutive securities — (1) — (1) 88 Weighted average common units - diluted 79,361 79,188 53,163 Calculation of Earnings per Unit - basic Income from continuing operations $ 350,745 $ 150,946 $ 37,692 Income from continuing operations allocated to unvested restricted shares (772 ) (278 ) (33 ) Income from continuing operations available for common unitholders, adjusted $ 349,973 $ 150,668 $ 37,659 Income from discontinued operations $ — $ 5,331 $ 69,852 Income from discontinued operations allocated to unvested restricted shares — (10 ) (62 ) Income from discontinued operations available for common unitholders, adjusted $ — $ 5,321 $ 69,790 Weighted average common units - basic 79,361 79,188 53,075 Earnings per unit - basic: $ 4.41 $ 1.97 $ 2.02 Calculation of Earnings per Unit - diluted Income from continuing operations $ 350,745 $ 150,946 $ 37,692 Income from continuing operations allocated to unvested restricted shares (772 ) (1) (278 ) (1) — Income from continuing operations available for common unitholders, adjusted $ 349,973 $ 150,668 $ 37,692 Income from discontinued operations $ — $ 5,331 $ 69,852 Income from discontinued operations allocated to unvested restricted shares — (1) (10 ) (1) — Income from discontinued operations available for common unitholders, adjusted $ — $ 5,321 $ 69,852 Weighted average common units - diluted 79,361 79,188 53,163 Earnings per unit - diluted: $ 4.41 $ 1.97 $ 2.02 (1) For both the years ended December 31, 2015 and 2014, 0.1 million potentially dilutive securities and their related income are not included in the diluted earnings per unit calculations as they are not dilutive.

Stock Based Compensation [Abstract]
Disclosure of Compensation Related Costs, Share-based Payments [Text Block]	5. STOCK BASED COMPENSATION Overview MAA accounts for its stock based employee compensation plans in accordance with accounting standards governing stock based compensation. These standards require an entity to measure the cost of employee services received in exchange for an award of an equity instrument based on the award's fair value on the grant date and recognize the cost over the period during which the employee is required to provide service in exchange for the award, which is generally the vesting period. Any liability awards issued are remeasured at each reporting period. MAA’s stock compensation plans consist of an employee stock purchase plan and a number of incentives provided to attract and retain independent directors, executive officers and key employees. Incentives are currently granted under the 2013 Stock Incentive Plan, as amended, which was originally approved at the September 27, 2013 annual meeting of MAA shareholders. The 2013 Stock Incentive Plan replaced the 2004 Stock Plan which had replaced the 1994 Restricted Stock and Stock Option Plan (collectively, the “Plans”) under which no further awards may be granted as of October 31, 2013. The 1994 Restricted Stock and Stock Option Plan allowed for the grant of restricted stock and stock options up to a total of 2.4 million shares. The 2004 Stock Plan allowed for the grant of restricted stock and stock options up to a total of 500,000 shares. The 2013 Stock Incentive Plan allows for the grant of restricted stock and stock options up to 625,000 shares. MAA believes that such awards better align the interests of its employees with those of its shareholders. Compensation expense is generally recognized for service based restricted stock awards using the straight-line method over the vesting period of the shares regardless of cliff or ratable vesting distinctions. Compensation expense for market and performance based restricted stock awards is generally recognized using the accelerated amortization method with each vesting tranche valued as a separate award, with a separate vesting date, consistent with the estimated value of the award at each period end. Additionally, we adjust compensation expense for estimated and actual forfeitures for all awards. Compensation expense for stock options is generally recognized on a straight-line basis over the requisite service period. MAA presents stock compensation expense in the Consolidated Statements of Operations on the line labeled “General and administrative expenses”. Total compensation costs under the Plans were approximately $6.9 million , $5.2 million and $2.7 million for the years ended December 31, 2015 , 2014 , and 2013 , respectively. Of these amounts, total compensation costs capitalized under the Plans were approximately $735,000 , $431,000 , and $17,000 for the years ended December 31, 2015 , 2014 , and 2013 , respectively. As of December 31, 2015 , the total unrecognized compensation cost related to the Plans was approximately $11.0 million . This cost is expected to be recognized over the remaining weighted average period of 1.2 years . Total cash paid for the settlement of plan shares totaled $1.0 million , $0.6 million , and $0.4 million for the years ended December 31, 2015 , 2014 , and 2013 , respectively. Information concerning grants under the Plans is listed below. Restricted Stock In general, restricted stock is earned based on either a service condition, performance condition, or market condition, or a combination thereof, and vests ratably over a period from 1 year to 5 years . Service based awards are earned when the employee remains employed over the requisite service period and are valued on the grant date based upon the market price of MAA common stock on the date of grant. Market based awards are earned when MAA reaches a specified stock price or specified return on the stock price (price appreciation plus dividends) and are valued on the grant date using a Monte Carlo simulation. Performance based awards are earned when MAA reaches certain operational goals such as FFO targets and are valued based upon the market price of MAA common stock on the date of grant as well as the probability of reaching the stated targets. MAA remeasures the fair value of the performance based awards each balance sheet date with adjustments made on a cumulative basis until the award is settled and the final compensation is known. The weighted average grant date fair value per share of restricted stock awards granted during the years ended December 31, 2015 , 2014 , and 2013 , was $68.35 , $62.40 , and $64.30 , respectively. The following is a summary of the key assumptions used in the valuation calculations for market based awards granted during the years ended December 31, 2015 , 2014 , and 2013 : 2015 2014 2013 Risk free rate - minimum 0.10% 0.02% 0.07% Risk free rate - maximum 1.05% 0.80% 0.17% Dividend yield 3.932% 4.755% 4.269% Volatility - minimum 15.41% 18.31% 16.40% Volatility - maximum 16.04% 20.48% 20.92% Service period 3 years 3 years 4 years The risk free rate was based on a zero coupon risk-free rate. The minimum risk free rate was based on a period of 0.25 years for the years ended December 31, 2015 , 2014 , and 2013 . The maximum risk free rate was based on a period of 3 years , 3 years , and 1 year for the years ended December 31, 2015 , 2014 , and 2013 , respectively. The dividend yield was based on the closing stock price of MAA stock on the date of grant. Volatility for MAA was obtained by using a blend of both historical and implied volatility calculations. Historical volatility was based on the standard deviation of daily total continuous returns, and implied volatility was based on the trailing month average of daily implied volatilities interpolating between the volatilities implied by stock call option contracts that were closest to the terms shown and closest to the money. The minimum volatility was based on a period of 1 year for the years ended December 31, 2015 , 2014 , and 2013 . The maximum volatility was based on a period of 2 years , 3 years , and 2 years for the years ended December 31, 2015 , 2014 , and 2013 , respectively. The requisite service period is based on the criteria for the separate programs according to the vesting schedule. Turnover is based on the historical experience for the key managers and executive officers, and is used in estimating forfeitures. A summary of the status of the nonvested restricted shares as of December 31, 2015 , and the changes for the year ended December 31, 2015 , is presented below: Nonvested Shares Shares Weighted Average Grant-Date Fair Value Nonvested at January 1, 2015 145,049 $ 63.25 Issued 93,356 72.54 Vested (49,156 ) 58.08 Forfeited (1,308 ) 65.88 Nonvested at December 31, 2015 187,941 $ 63.36 The total fair value of shares vesting during the years ended December 31, 2015 , 2014 , and 2013 was approximately $2.9 million , $2.7 million , and $1.6 million , respectively. Stock Options In general, stock options are earned when the employee remains employed over the requisite service period and vest ratably over a period from 0.3 years to 2.3 years . Stock options exercised result in new common shares being issued on the open market by the Company. The fair value of stock option awards is determined using the Black-Scholes valuation model. The weighted average grant date fair value of stock option awards granted during the year ended December 31, 2013 was $11.77 per option. No stock options were granted during the years ended December 31, 2015 and 2014 . The following is a summary of the key assumptions used in the Black-Scholes valuation calculations for stock options granted during the year ended December 31, 2013 : 2013 Term - minimum 0.25 years Term - maximum 5.50 years Risk free rate - minimum 0.02% Risk free rate - maximum 1.55% Dividend yield 4.21% Volatility - minimum 15.60% Volatility - maximum 46.29% The term represents an estimate of the period of time options are expected to remain outstanding. The U.S. Treasury bill rate, which approximated the expected life of the option, was used to represent the risk-free rate. The current dividend yield at the time of grant was used to estimate the dividend yield over the life of the option. Volatility is based on the actual changes in the market value of MAA’s stock and is calculated using daily market value changes from the date of grant over a past period equal to the expected life of the stock options. Turnover is based on the historical rate at which options are exercised, and is used in estimating forfeitures. A summary of the status of the stock options as of December 31, 2015 and the changes for the year ended December 31, 2015 is presented below: Stock Options Options Weighted Average Exercise Price Outstanding at January 1, 2015 74,454 $ 82.33 Granted — — Exercised (7,342 ) 57.23 Expired (9,000 ) 76.87 Outstanding at December 31, 2015 58,112 $ 86.21 All 58,112 options outstanding at December 31, 2015 were exercisable with a weighted average exercise price of $86.21 , an intrinsic value of $835,000 , and a weighted average remaining term of 1.7 years . The intrinsic value of options exercised during the year ended December 31, 2015 was $0.2 million . Cash received from the exercise of stock options for the years ended December 31, 2015 , 2014 , and 2013 was $0.4 million , $12.2 million , and $6.2 million , respectively.

Borrowings [Abstract]
BORROWINGS	BORROWINGS The weighted average interest rate at December 31, 2015 for the $3.43 billion of debt outstanding was 3.7% , compared to the weighted average interest rate of 3.7% on $3.51 billion of debt outstanding at December 31, 2014 . Our debt consists of an unsecured credit facility, unsecured term loans, senior unsecured notes, a secured credit facility with Fannie Mae, and secured property mortgages. We utilize fixed rate borrowings, interest rate swaps, and interest rate caps to manage our current and future interest rate risk. More details on our borrowings can be found in the schedules presented later in this section. At December 31, 2015 , the Company had $65.0 million (after considering the impact of interest rate swap and cap agreements in effect) of conventional, secured variable rate debt outstanding at an average interest rate of 0.8% , $125.0 million of capped conventional, secured variable rate debt at an average interest rate of 0.8% . The interest rate on all other secured debt, totaling $1.1 billion , was hedged or fixed at an average interest rate of 4.0% . Additionally, the Company had $2.1 billion of senior unsecured notes and term loans fixed at an average interest rate of 3.9% and a $750 million variable rate credit facility with an average interest rate of 1.2% with $75 million borrowed at December 31, 2015 . Unsecured Credit Facility We also maintain a $750.0 million unsecured credit facility with fourteen banks led by KeyBank National Association, or the KeyBank Facility. The KeyBank Facility includes an expansion option up to $1.5 billion . The KeyBank Facility bears an interest rate of LIBOR plus a spread of 0.85% to 1.55% based on an investment grade pricing grid and is currently bearing interest at 1.23% . This credit line expires in April 2020 with an option to extend for an additional six months. At December 31, 2015 , we had $746.7 million available to be borrowed under the Key Bank Line agreement with $75.0 million actually borrowed under this facility. Approximately $3.3 million of the facility is used to support letters of credit. Commitment fees related to this facility totaled $1.1 million for the year ended December 31, 2015 . Unsecured Term Loans We also maintain three term loans with a syndicate of banks, led by KeyBank, Wells Fargo, and US Bank, respectively. The KeyBank term loan has a balance of $150 million , matures in 2021, and has a variable interest rate of LIBOR plus a spread of 0.90% to 1.75% based on our credit ratings. The Wells Fargo term loan has a balance of $250 million and matures in 2018. The US Bank term loan has a balance of $150 million and matures in 2020. Both the Wells Fargo and US Bank term loans have variable interest rates of LIBOR plus a spread of 0.90% to 1.90% based on our credit ratings. Senior Unsecured Notes As of December 31, 2015 , we had approximately $1.2 billion of publicly issued bonds and $310.0 million of private placement notes. These senior unsecured notes are longer term in nature and usually mature within five to twelve years. On November 2, 2015, the Operating Partnership issued $400 million in aggregate principal amount of notes, maturing on November 15, 2025 with an interest rate of 4.00% per annum, or the 2025 Notes. The purchase price paid by the initial purchasers was 98.99% of the principal amount. The 2025 Notes are general unsecured senior obligations of the Operating Partnership and rank equally in right of payment with all other senior unsecured indebtedness of the Operating Partnership. Interest on the 2025 Notes is payable on May 15 and November 15 of each year, beginning on May 15, 2016. The net proceeds from the offering after deducting the original issue discount of approximately $4.0 million and underwriting commissions and expenses of approximately $2.6 million were approximately $393.4 million . The 2025 Notes have been reflected net of discount and debt issuance costs in the Consolidated Balance Sheet. In connection with the bond transaction, we cash settled $200 million in forward interest rate swap agreements, entered earlier in the year to effectively lock the interest rate on the planned transaction, which produced an effective interest rate of 4.17% over the ten year life of the bonds. The Indentures under which certain public notes were issued, including the 2025 Notes, contain certain covenants that, among other things, limit the ability of MAALP and its subsidiaries to incur secured and unsecured indebtedness if not in pro forma compliance with the following negative covenants: (1) total leverage not to exceed 60% of adjusted total assets; (2) secured leverage not to exceed 40% of adjusted total assets; and (3) a fixed charge coverage ratio of at least 1.50 to 1. In addition, MAALP is required to maintain at all times unencumbered consolidated total assets of not less than 150% of the aggregate principal amount of its outstanding unsecured debt. At December 31, 2015, MAALP was in compliance with each of these financial covenants. Secured Credit Facility We maintain a $240.0 million secured credit facility with Prudential Mortgage Capital, which is credit enhanced by Fannie Mae, or Fannie Mae Facility. The Fannie Mae Facility provides for both fixed and variable rate borrowings and have Fannie Mae rate tranches with maturities from 2016 through 2018. The interest rate on the majority of the variable portion renews every 90 days and is based on the FNMA discount mortgage backed security rate on the date of renewal, which, for the Company, has historically approximated three-month LIBOR less an average of 0.17% over the life of the Fannie Mae Facility, plus a fee of 0.62% . Borrowings under the Fannie Mae Facility totaled $240.0 million at December 31, 2015 , consisting of $50.0 million under a fixed portion at a rate of 4.7% , and the remaining $190.0 million under the variable rate portion of the facility at an average rate of 0.8% . The available borrowing capacity at December 31, 2015 , was $240.0 million . Commitment fees related to our unused Fannie Mae Facility totaled $0.1 million for the year ended December 31, 2015 . The Company has also entered into 5 interest rate caps totaling a notional amount of $125.0 million which are designed to cap a portion of the Fannie Mae Facility. These interest rate caps have maturities between 2016 and 2018 with four set at 4.5% and one set at 5.0% . The Fannie Mae Facility is subject to certain borrowing base calculations that can effectively reduce the amount that may be borrowed. Secured Property Mortgages At December 31, 2015 , the Company had $1.0 billion of fixed rate conventional property mortgages with an average interest rate of 3.9% and an average maturity in 2019. On January 30, 2015, we paid off a $15.2 million mortgage associated with the Farmington Village apartment community. We recorded a $0.2 million loss on debt extinguishment due to paying off the mortgage prior to maturity. On June 1, 2015, we paid off a $25.5 million mortgage associated with the Colonial Grand at Wilmington apartment community. The payoff was a scheduled maturity of the loan. On June 15, 2015, we paid off a $10.1 million mortgage associated with the Reserve at Woodwind Lakes apartment community. The payoff was a scheduled maturity of the loan. On September 1, 2015, we paid off a $11.6 million mortgage associated with the Colonial Village at Timber Crest apartment community. The payoff was a scheduled maturity of the loan. On September 30, 2015, we paid off a $23.5 million mortgage associated with the Sanctuary at Oglethorpe apartment community. The payoff was a scheduled maturity of the loan. In addition to these payoffs, we have paid $8.2 million associated with property mortgage principal amortizations for the year ended December 31, 2015. Guarantees MAA fully and unconditionally guarantees the following debt incurred by the Operating Partnership: • $240.0 million of the Fannie Mae Facility, of which $240.0 million has been borrowed as of December 31, 2015 ; and • $310.0 million of senior unsecured notes, all of which has been borrowed as of December 31, 2015 .

Notes To Financial Statements [Abstract]
DERIVATIVES AND HEDGING ACTIVITIES	DERIVATIVES AND HEDGING ACTIVITIES Risk Management Objective of Using Derivatives We are exposed to certain risks arising from both business operations and economic conditions. We principally manage our exposures to a wide variety of business and operational risks through management of our core business activities. We manage economic risks, including interest rate, liquidity and credit risk, primarily by managing the amount, sources and duration of our debt funding and the use of derivative financial instruments. Specifically, we enter into derivative financial instruments to manage exposures that arise from business activities that result in the payment of future contractual and forecasted cash amounts, principally related to the our borrowings, the value of which are determined by changing interest rates, related cash flows and other factors. Cash Flow Hedges of Interest Rate Risk Our objectives in using interest rate derivatives are to add stability to interest expense and to manage our exposure to interest rate movements. To accomplish this objective, we use interest rate swaps and interest rate caps as part of our interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for us making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. Interest rate caps designated as cash flow hedges involve the receipt of variable amounts from a counterparty if interest rates rise above the strike rate on the contract in exchange for an up-front premium. The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in Accumulated other comprehensive income and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. During the years ended December 31, 2015 , 2014 and 2013 , such derivatives were used to hedge the variable cash flows associated with existing variable-rate debt and forecasted issuances of fixed-rate debt. The ineffective portion of the change in fair value of the derivatives is recognized directly in earnings. During the years ended December 31, 2015 , 2014 and 2013 , we recorded ineffectiveness of $100,000 (increase to interest expense), $157,000 (increase to interest expense) and $37,000 (decrease to interest expense), respectively, mainly attributable to a mismatch in the underlying indices of the derivatives and the hedged interest payments made on our variable-rate debt and due to the designation of acquired interest rate swaps with a non-zero fair value at inception. Amounts reported in "Accumulated other comprehensive income" related to derivatives designated as qualifying cash flow hedges will be reclassified to Interest expense as interest payments are made on our variable-rate or fixed-rate debt. During the next twelve months, we estimate that an additional $3.1 million will be reclassified to earnings as an increase to Interest expense, which primarily represents the difference between our fixed interest rate swap payments and the projected variable interest rate swap payments. As of December 31, 2015 , we had the following outstanding interest rate derivatives that were designated as cash flow hedges of interest rate risk: Interest Rate Derivative Number of Instruments Notional Interest Rate Caps 5 $125,000,000 Interest Rate Swaps 7 $550,000,000 The fair value of our interest rate derivatives designated as hedging instruments at December 31, 2015 included $6,000 of asset derivatives reported in Other assets and $10,358,000 of liability derivatives reported in the Fair market value of interest rate swaps in the Consolidated Balance Sheet. The fair value of our interest rate derivatives designated as hedging instruments at December 31, 2014 included $72,000 of asset derivatives reported in Other Assets and $13,392,000 of liability derivatives reported in Fair market value of interest rate swaps in the Consolidated Balance Sheet. As of December 31, 2014, we also reported a fair value of $6,000 in interest rate derivatives recorded in Other assets related to derivatives not designated as hedging instruments. Tabular Disclosure of the Effect of Derivative Instruments on the Statement of Operations The tables below present the effect of our derivative financial instruments on the Consolidated Statement of Operations for the years ended December 31, 2015 , 2014 and 2013 , respectively (dollars in thousands): Derivatives in Cash Flow Hedging Relationships Amount of Gain or (Loss) Recognized in OCI on Derivative (Effective Portion) Location of Gain or (Loss) Reclassified from Accumulated OCI into Income (Effective Portion) Amount of Gain or (Loss) Reclassified from Accumulated OCI into Income (Effective Portion) Location of Gain or (Loss Recognized in Income on Derivative (Ineffective Portion and Amount Excluded from Effectiveness Testing) Amount of Gain or (Loss) Recognized in Income on Derivative (Ineffective Portion and Amount Excluded from Effectiveness Testing) Years ended December 31, 2015 2014 2013 2015 2014 2013 2015 2014 2013 Interest rate contracts $ (8,306 ) $ (12,335 ) $ 10,684 Interest expense $ (7,064 ) $ (11,785 ) $ (16,370 ) Interest expense $ (100 ) $ (157 ) $ 37 Total derivatives in cash flow hedging relationships $ (8,306 ) $ (12,335 ) $ 10,684 $ (7,064 ) $ (11,785 ) $ (16,370 ) $ (100 ) $ (157 ) $ 37 Derivatives Not Designated as Hedging Instruments Location of Gain or (Loss) Recognized in Income on Derivative Amount of Gain or (Loss) Recognized in Income on Derivative For the year ended December 31, 2015 2014 2013 Interest rate products Interest income/(expense) $ (3 ) $ (146 ) $ (16 ) Total $ (3 ) $ (146 ) $ (16 ) Credit-risk-related Contingent Features As of December 31, 2015 , derivatives that were in a net liability position and subject to credit-risk-related contingent features had a termination value of $11.2 million , which includes accrued interest but excludes any adjustment for nonperformance risk. These derivatives had a fair value, gross of asset positions, of $10.4 million at December 31, 2015 . Certain of our derivative contracts contain a provision where we could be declared in default on our derivative obligations if repayment of the underlying indebtedness is accelerated by the lender due to our default on the indebtedness. As of December 31, 2015 , we had not breached the provisions of these agreements. If we had breached these provisions, we could have been required to settle our obligations under the agreements at the termination value of $11.2 million . Although our derivative contracts are subject to master netting arrangements, which serve as credit mitigants to both us and our counterparties under certain situations, we do not net our derivative fair values or any existing rights or obligations to cash collateral on the consolidated Balance Sheet. We did not have any asset or liability derivative balances that were offsetting that would have resulted in reported net derivative balances differing from the recorded gross amount of derivative assets of $6,000 and $78,000 as of December 31, 2015 and 2014, respectively, in addition to gross recorded derivative liabilities of $10,358,000 and $13,392,000 as of December 31, 2015 and 2014, respectively. Other Comprehensive Income MAA's other comprehensive income consists entirely of gains and losses attributable to the effective portion of our cash flow hedges. The chart below shows the change in the balance for the years ended December 31, 2015 , 2014 , and 2013 : Changes in Accumulated Other Comprehensive Income (Loss) by Component Affected Line Item in the Consolidated Statements Of Operations Gains and Losses on Cash Flow Hedges For the year ended December 31, 2015 2014 2013 Beginning balance $ (412 ) $ 108 $ (26,054 ) Other comprehensive (loss) income before reclassifications (8,306 ) (12,335 ) 10,684 Amounts reclassified from accumulated other comprehensive income (interest rate contracts) Interest (income)/expense 7,064 11,785 16,370 Net current-period other comprehensive loss (income) attributable to noncontrolling interest 65 30 (892 ) Net current-period other comprehensive (loss) income attributable to MAA (1,177 ) (520 ) 26,162 Ending balance $ (1,589 ) $ (412 ) $ 108 See also discussions in Note 8 (Fair Value Disclosure of Financial Instruments) below.

Notes To Financial Statements [Abstract]
Fair Value Disclosure of Financial Instruments	FAIR VALUE DISCLOSURE OF FINANCIAL INSTRUMENTS Cash and cash equivalents, restricted cash, accounts payable, accrued expenses and other liabilities and security deposits are carried at amounts that reasonably approximate their fair value due to their short term nature. We apply FASB ASC, 820 Fair Value Measurements and Disclosures, or ASC 820. ASC 820 defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements. ASC 820 applies to reported balances that are required or permitted to be measured at fair value under existing accounting pronouncements; accordingly, the standard does not require any new fair value measurements of reported balances. ASC 820 emphasizes that fair value is a market-based measurement, not an entity-specific measurement. Therefore, a fair value measurement should be determined based on the assumptions that market participants would use in pricing the asset or liability. As a basis for considering market participant assumptions in fair value measurements, ASC 820 establishes a fair value hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are classified within Levels 1 and 2 of the hierarchy) and the reporting entity’s own assumptions about market participant assumptions (unobservable inputs classified within Level 3 of the hierarchy). Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that we have the ability to access. Level 2 inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs may include quoted prices for similar assets and liabilities in active markets, as well as inputs that are observable for the asset or liability (other than quoted prices), such as interest rates, foreign exchange rates, and yield curves that are observable at commonly quoted intervals. Level 3 inputs are unobservable inputs for the asset or liability, which are typically based on an entity’s own assumptions, as there is little, if any, related market activity. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. Our assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability. Fixed rate notes payable at December 31, 2015 and December 31, 2014 , totaled $2.61 billion and $2.50 billion , respectively, and had estimated fair values of $2.71 billion and $2.54 billion (excluding prepayment penalties), respectively, as of December 31, 2015 and December 31, 2014 . The carrying value of variable rate notes payable (excluding the effect of interest rate swap and cap agreements) at December 31, 2015 and December 31, 2014 , totaled $0.82 billion and $1.02 billion , respectively, and had estimated fair values of $0.82 billion and $0.97 billion (excluding prepayment penalties), respectively, based upon observable interest rates available for the issuance of debt with similar terms and remaining maturities as of December 31, 2015 and December 31, 2014 . The valuation of our debt is determined using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each debt instrument. This analysis reflects the contractual terms of the debt, and uses observable market-based inputs, including interest rate curves and credit spreads. The fair values of fixed debt are determined by using the present value of future cash outflows discounted with the applicable current market rate plus a credit spread. The fair values of variable debt are determined using the stated variable rate plus the current market credit spread. Our variable rates reset every 30 to 90 days and we conclude that these rates reasonably estimate current market rates. We have determined that inputs used to value our debt fall within Level 2 of the fair value hierarchy and therefore our fair market valuation of debt is considered Level 2 in the fair value hierarchy. Currently, we use interest rate swaps and interest rate caps (options) to manage our interest rate risk. The valuation of these instruments is determined using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. The fair values of interest rate swaps are determined using the market standard methodology of netting the discounted future fixed cash receipts (or payments) and the discounted expected variable cash payments (or receipts). The variable cash payments (or receipts) are based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves. The fair values of interest rate options are determined using the market standard methodology of discounting the future expected cash receipts that would occur if variable interest rates rise above the strike rate of the caps. The variable interest rates used in the calculation of projected receipts on the cap are based on an expectation of future interest rates derived from observable market interest rate curves and volatilities. To comply with the provisions of ASC 820, we incorporate credit valuation adjustments to appropriately reflect both our own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of our derivative contracts for the effect of nonperformance risk, we have considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts and guarantees. In conjunction with the FASB's fair value measurement guidance, we made an accounting policy election to measure the credit risk of our derivative financial instruments that are subject to master netting agreements on a net basis by counterparty portfolio. We have determined that the majority of the inputs used to value our derivatives fall within Level 2 of the fair value hierarchy, and as a result, all of our derivatives held as of December 31, 2015 and December 31, 2014 were classified as Level 2 of the fair value hierarchy. The table below presents our assets and liabilities measured at fair value on a recurring basis as of December 31, 2015 and December 31, 2014 , aggregated by the level in the fair value hierarchy within which those measurements fall. Assets and Liabilities Measured at Fair Value on a Recurring Basis at December 31, 2015 (dollars in thousands) Quoted Prices in Active Markets for Identical Assets and Liabilities (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Balance at December 31, 2015 Assets Derivative financial instruments $ — $ 6 $ — $ 6 Liabilities Derivative financial instruments $ — $ 10,358 $ — $ 10,358 Assets and Liabilities Measured at Fair Value on a Recurring Basis at December 31, 2014 (dollars in thousands) Quoted Prices in Active Markets for Identical Assets and Liabilities (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Balance at December 31, 2014 Assets Derivative financial instruments $ — $ 78 $ — $ 78 Liabilities Derivative financial instruments $ — $ 13,392 $ — $ 13,392 The fair value estimates presented herein are based on information available to management as of December 31, 2015 and December 31, 2014 .

Income Taxes [Abstract]
INCOME TAXES	INCOME TAXES For income tax purposes, dividends paid to holders of common stock primarily consist of ordinary income, return of capital, capital gains, qualified dividends and un-recaptured Section 1250 gains, or a combination thereof. For the years ended December 31, 2015, 2014 and 2013, dividends per share held for the entire year were estimated to be taxable as follows: 2015 2014 2013 Amount Percentage Amount Percentage Amount Percentage Ordinary income $ 3.07 99.7 % $ 2.76 94.41 % $ 2.36 84.9 % Capital gains — — % — — % 0.17 6.23 % Return of capital — — % 0.16 5.59 % — — % Un-recaptured Section 1250 gain 0.01 0.3 % — — % 0.25 8.87 % $ 3.08 100.00 % $ 2.92 100.00 % $ 2.78 100.00 % We designated the per share amounts above as capital gain dividends in accordance with the requirements of the Code. The difference between net income available to common shareholders for financial reporting purposes and taxable income before dividend deductions relates primarily to temporary differences such as depreciation and amortization, and deferral of gains on sold properties utilizing like kind exchanges under Internal Revenue Code, or IRC, section 1031. Merger and Restructuring As discussed in Note 2 (Business Combinations), on October 1, 2013, we completed our merger with Colonial and Colonial LP. Pursuant to the merger agreement, OP Merger Sub merged with and into Colonial LP, with Colonial LP being the surviving entity of the merger and becoming a wholly-owned indirect subsidiary of MAALP. We believe that this transaction constitutes a tax free merger under Code section 708. Immediately thereafter, MAA and Colonial combined through a merger of Colonial with and into MAA, with MAA surviving the merger. We believe that this merger constitutes a tax free merger under Code section 368(a). As a result of the tax free merger treatment, the merger transactions did not result in the recognition of a gain to any security holder of MAA, Colonial, MAALP, or Colonial LP. On October 1, 2013, MAA re-identified hedging transactions for federal income tax purposes according to Reg. §1.1221-2(f) and all relevant state income tax purposes that were previously held by Colonial. This re-identification was made because the tax identity of Colonial changed by virtue of the merger into MAA. There were four hedging transactions re-identified for tax purposes, including the $50 million interest rate swap with Wells Fargo Bank, N.A. ("Wells Fargo") with a fixed interest rate of 2.465% , the $200 million interest rate swap with Wells Fargo with a fixed interest rate of 2.576% , the $50 million interest rate swap with Wells Fargo with a fixed interest rate of 1.064% , and the $100 million interest rate swap with Wells Fargo with a fixed interest rate of 1.133% . Taxable REIT subsidiaries We acquired the operations of a TRS, Colonial Properties Services, Inc., or CPSI, through the Merger. As a result, CPSI’s tax attributes are now included in the MAA consolidated financial statements. A TRS is an entity which is not entitled to a dividends paid deduction and is subject to Federal, state, and local income taxes. Formerly, CPSI provided property development, construction, leasing and management services for joint venture and third-party owned properties and administrative services to MAA and engaged in for-sale development activity. CPSI also owns and operates two multifamily apartment communities. We generally reimburse CPSI for payroll and other costs incurred in providing services to us. All inter-company transactions are eliminated in the accompanying consolidated financial statements. We also hold certain undeveloped land through another TRS, MAA Copper Ridge, Inc. During the years ended December 31, 2015, 2014, and 2013, our TRSs recognized no income tax expense/(benefit). CPSI uses the liability method of accounting for income taxes. Deferred income tax assets and liabilities result from temporary differences. Temporary differences are differences between tax bases of assets and liabilities and their reported amounts in the financial statements that will result in taxable or deductible amounts in future periods. The net deferred tax assets of the Company, consisting of the net deferred tax assets of CPSI and the net-loss deferred tax asset acquired by MAA from Colonial, have been fully offset by a valuation allowance. We record a valuation allowance against our net deferred tax assets when we determine that based on the weight of available evidence, it is more likely than not that our net deferred tax assets will not be realized. We considered the four sources of taxable income that should be considered when determining whether a valuation allowance is required (from least to most subjective): • taxable income in prior carryback years, if carryback is permitted under the tax law; • future reversals of existing taxable temporary differences (i.e., offset gross deferred tax assets against gross deferred tax liabilities); • tax planning strategies; and • future taxable income exclusive of reversing temporary differences and carryforwards. For the years ended December 31, 2015 and 2014, the components of CPSI’s deferred income tax assets and liabilities were as follows (dollars in thousands): December 31, 2015 December 31, 2014 Deferred tax assets: Real estate asset basis differences $ 25,627 $ 25,561 Deferred revenue 22 18 Deferred expenses 14,106 13,923 Net operating loss carryforward 28,493 27,215 Accrued liabilities 3,951 3,974 $ 72,199 $ 70,691 Deferred tax liabilities: Real estate asset basis differences $ (145 ) $ (913 ) $ (145 ) $ (913 ) Net deferred tax assets, before valuation allowance $ 72,054 $ 69,778 Valuation allowance (72,054 ) (69,778 ) Net deferred tax assets, included in other assets $ — $ — For the years ended December 31, 2015, 2014 and 2013, the reconciliation of income tax attributable to continuing operations for the TRSs computed at the U.S. statutory rate to the income tax provision was as follows (dollars in thousands): December 31, 2015 December 31, 2014 December 31, 2013 Tax expense/(benefit) at U.S. statutory rates on TRS income subject to tax $ 2,506 $ 1,802 $ (261 ) Effect of permanent differences and other (730 ) (1,110 ) 1 (Decrease) increase in valuation allowance (1,776 ) (692 ) 260 TRS income tax provision $ — $ — $ — At December 31, 2015 and 2014, CPSI had net operating loss, or NOL carryforwards of approximately $66.0 million and $63.1 million , respectively, for income tax purposes that expire in years 2031 to 2034. Utilization of the Company’s NOL carryforwards is subject to an annual limitation due to ownership change limitations provided by Section 382 of the Code and similar state provisions. The annual limitations may result in the expiration of NOL carryforwards before utilization. CPSI generated approximately $0.3 million of taxable income before NOL carryforwards for the period ended December 31, 2015. We had no reserve for uncertain tax positions for the years ended December 31, 2015, 2014 and 2013. If necessary, the Company accrues interest and penalties on unrecognized tax benefits as a component of income tax expense. For the years ended December 31, 2015, 2014, and 2013, other expenses include estimated state franchise and other taxes, including franchise taxes in North Carolina and Tennessee. The income tax expense line item shown in the Consolidated Statement of Operations represents the Texas-based margin tax for all Texas properties. As of December 31, 2015, MAA held NOL carryforwards of approximately $46.3 million for income tax purposes that expire in years 2019 to 2031. We may use these NOLs to offset all or a portion of the taxable income generated at the REIT level. Tax years 2012 through 2015 are subject to examination by the Internal Revenue Service. No tax examination is currently in process.

Partners' Capital of MAA LP

Partners' Capital of MAA LP [Abstract]
Partners' Capital Notes Disclosure [Text Block]	PARTNERS' CAPITAL OF MAALP Operating Partnership Units Interests in MAALP are represented by Operating Partnership Units, or OP Units. As of December 31, 2015 , there were 79,571,567 OP Units outstanding, 75,408,571 or 94.8% of which were owned by MAA, MAALP's general partner. The remaining 4,162,996 OP Units were owned by non-affiliated limited partners, or Class A Limited Partners. As of December 31, 2014 , there were 79,458,827 OP Units outstanding, 75,267,675 or 94.7% of which were owned by MAA and 4,191,152 of which were owned by the Class A Limited Partners. MAA, as the sole general partner of MAALP, has full, complete and exclusive discretion to manage and control the business of the Operating Partnership subject to the restrictions specifically contained within the Partnership Agreement. Unless otherwise stated in the Partnership Agreement of MAALP, this power includes, but is not limited to, acquiring, leasing, or disposing of any real property; constructing buildings and making other improvements to properties owned; borrowing money, modifying or extinguishing current borrowings, issuing evidence of indebtedness, and securing such indebtedness by mortgage, deed of trust, pledge or other lien on the Operating Partnership's assets; and distribution of Operating Partnership cash or other assets in accordance with the Partnership Agreement. MAA can generally, at its sole discretion, issue and redeem OP Units and determine the consideration to be received or the redemption price to be paid, as applicable. The general partner may delegate these and other powers granted if the general partner remains in supervision of the designee. Under the Partnership Agreement, the Operating Partnership may issue Class A Units and Class B Units. Class A Units may only be held by limited partners who are not affiliated with MAA, in its capacity as general partner of the Operating Partnership, while Class B Units may only be held by MAA, in its capacity as general partner of the Operating Partnership, and as of December 31, 2015 , a total of 4,162,996 Class A Units in the Operating Partnership were held by limited partners unaffiliated with MAA, while a total of 75,408,571 Class B Units were held by MAA. In general, the limited partners do not have the power to participate in the management or control of the Operating Partnership's business except in limited circumstances including changes in the general partner and protective rights if the general partner acts outside of the provisions provided in the Partnership Agreement. The transferability of Class A Units is also limited by the Partnership Agreement. Net income is allocated to the general partner and limited partners based on their respective ownership percentages of the Operating Partnership. Issuance or redemption of additional Class A Units or Class B Units changes the relative ownership percentage of the partners. The issuance of Class B Units generally occurs when MAA issues common stock and the proceeds from that issuance are contributed to the Operating Partnership in exchange for the issuance to MAA of a number of OP Units equal to the number of shares of common stock issued. Likewise, if MAA repurchases or redeems outstanding shares of common stock, the Operating Partnership generally redeems an equal number of Class B Units with similar terms held by MAA for a redemption price equal to the purchase price of those shares of common stock. At each reporting period, the allocation between general partner capital and limited partner capital is adjusted to account for the change in the respective percentage ownership of the underlying capital of the Operating Partnership. Holders of the Class A Units may require MAA to redeem their Class A Units, in which case MAA may, at its option, pay the redemption price either in cash (in an amount per Class A Unit equal, in general, to the average closing price of MAA's common stock on the New York Stock Exchange over a specified period prior to the redemption date) or by delivering one share of MAA common stock (subject to adjustment under specified circumstances) for each Class A Unit so redeemed. At December 31, 2015 , a total of 4,162,996 Class A Units were outstanding and redeemable for 4,162,996 shares of MAA common stock, with an approximate value of $378,041,667 , based on the closing price of MAA’s common stock on December 31, 2015 of $90.81 per share. At December 31, 2014 , a total of 4,191,152 Class A Units were outstanding and redeemable for 4,191,152 shares of MAA common stock, with an approximate value of $312,995,231 , based on the closing price of MAA’s common stock on December 31, 2014 of $74.68 per share. The Operating Partnership pays the same per unit distribution in respect to the OP Units as the per share dividend MAA pays in respect to its common and preferred stock.

Employee Benefit Plans [Abstract]
EMPLOYEE BENEFIT PLANS	EMPLOYEE BENEFIT PLANS Following are details of employee benefit plans not previously discussed in Note 5 (Stock Based Compensation). 401(k) Savings Plan MAA's 401(k) Savings Plan, or 401(k) Plan, is a defined contribution plan that satisfies the requirements of Section 401(a) and 401(k) of the Code. MAA's Board of Directors has the discretion to approve matching contributions. MAA's contributions to this plan were approximately $1.0 million , $0.9 million and $0.7 million for the years ended December 31, 2015 , 2014 and 2013 , respectively. Non-Qualified Deferred Compensation Retirement Plan MAA has adopted a non-qualified deferred compensation retirement plan for key employees who are not qualified for participation in MAA’s 401(k) Plan. Under the terms of the plan, employees may elect to defer a percentage of their compensation and MAA may, but is not obligated to, match a portion of their salary deferral. MAA’s match to this plan for the years ended December 31, 2015 , 2014 and 2013 was approximately $106,000 , $82,000 and $46,000 , respectively. Non-Qualified Deferred Compensation Plan for Outside Company Directors In 1998, MAA established the Non-Qualified Deferred Compensation Plan for Outside Company Directors, or the Directors Deferred Compensation Plan, which allows non-employee directors to defer their director fees by having the fees held by MAA as shares of MAA's common stock. Directors can also choose to have their annual restricted stock grants issued into the Directors Deferred Compensation Plan. Amounts deferred through the Directors Deferred Compensation Plan are distributed to the directors in two annual installments beginning in the first 90 days of the year following the director’s departure from the board. Participating directors may choose to have the amount issued to them in shares of MAA's common stock or paid to them as cash at the market value of MAA's common stock as of the end of the year the director ceases to serve on the board. For the years ended December 31, 2015 , 2014 and 2013 , directors deferred 8,466 shares, 9,415 shares and 7,173 shares of common stock, respectively, with weighted-average grant date fair values of $78.62 , $70.63 and $66.77 , respectively, into the Directors Deferred Compensation Plan. The shares of common stock held in the Directors Deferred Compensation Plan are classified outside of permanent equity in redeemable stock with changes in redemption amount recorded immediately to retained earnings because the directors have redemption rights not solely within the control of MAA. Additionally, any shares that become mandatorily redeemable because a departed director has elected to receive a cash payout are recorded as a liability. MAA did not record a liability related to mandatorily redeemable shares for the years ended December 31, 2015 , 2014 and 2013 . Employee Stock Ownership Plan MAA's Employee Stock Ownership Plan, or ESOP, is a non-contributory stock bonus plan that satisfies the requirements of Section 401(a) of the Code. Each of our employees is eligible to participate in the ESOP after completing one year of service. Participants' ESOP accounts will be 100% vested after three years of continuous service, with no vesting prior to that time. MAA contributed 22,500 shares of common stock to the ESOP upon conclusion of the initial offering. The Company did not contribute to the ESOP during 2015 , 2014 or 2013 . As of December 31, 2015 , there were 155,309 shares outstanding with a fair value of $14.1 million .

Legal Proceedings
Legal Matters and Contingencies [Text Block]	LEGAL PROCEEDINGS We, along with multiple other parties, are named defendants in two lawsuits arising out of alleged construction deficiencies with respect to condominium units at Regatta at James Island in Charleston, South Carolina. The Regatta at James Island property was developed and constructed by certain of Colonial's subsidiaries prior to the Merger. The condominiums were constructed in 2006 and all 212 units were sold. The lawsuits, one filed on behalf of the condominium homeowners association and one filed by three of the unit owners (purportedly on behalf of all unit owners), were filed in South Carolina state court (Charleston County) in August 2012, against various parties involved in the development and construction of the Regatta at James Island property, including the contractors, subcontractors, architect, developer, and product manufacturers. The plaintiffs are seeking damages resulting primarily from alleged construction deficiencies, but the amount the plaintiffs seek to recover has not been disclosed. The lawsuits are currently in discovery. We are continuing to investigate the matter and evaluate our options and intend to vigorously defend ourself against these claims. No assurance can be given that the matter will be resolved favorably to us. We have included in our loss contingency an estimate of probable loss in connection with this matter, but currently cannot reasonably estimate any further possible loss, or any range of reasonably possible loss, in connection with this matter. In addition, we are subject to various other legal proceedings and claims that arise in the ordinary course of its business operations. Matters which arise out of allegations of bodily injury, property damage, and employment practices are generally covered by insurance. While the resolution of these other matters cannot be predicted with certainty, management currently believes the final outcome of such matters will not have a material adverse effect on the financial position, results of operations or cash flows of the Company. Loss Contingencies See discussion of our accounting for loss contingencies in Note 1 (Organization and Summary of Significant Accounting Polices). As of December 31, 2015 and December 31, 2014 , the Company's accrual for loss contingencies was $13.5 million and $12.3 million in the aggregate, respectively.

Related Party Transactions [Abstract]
RELATED PARTY TRANSACTIONS	RELATED PARTY TRANSACTIONS At various times throughout the years ended December 31, 2014 and 2013, the Company managed the operations of certain joint venture apartment communities for a fee of 4.00% to 4.25% of the revenues of the joint venture, pursuant to management contracts with the Company's joint ventures. The Company received $154,000 and $647,000 as management fees from the joint ventures for the years ended December 31, 2014 and 2013 , respectively, as compared to none for the year ended December 31, 2015. The Company also received approximately $19,000 and $93,000 in asset management fees for the years ended December 31, 2014 and 2013 , respectively, as compared to none for the year ended December 31, 2015. The Company had receivables from joint ventures totaling $15,000 , and $1,800,000 , as of December 31, 2014 and 2013 , respectively, as compared to no receivables from joint ventures at December 31, 2015. In addition to management contracts with joint ventures, the Company also receives advertising fees from a related party insurance company, Colonial Insurance Agency. These fees are received for allowing Colonial Insurance Agency to sell renter's insurance at some of the Company's multifamily properties. This agreement expired during 2015. The Company received approximately $154,000 , $300,000 , and $70,000 as advertising revenue for the years ended December 31, 2015 , 2014 and 2013 , respectively. All cash management of the Company is managed by the Operating Partnership. In general, cash receipts are remitted to the Operating Partnership and all cash disbursements are funded by the Operating Partnership. As a result of these transactions, the Operating Partnership had a payable to its General Partner (MAA) of $19,000 at each of the years ended December 31, 2015 , 2014 , and 2013 . The Partnership Agreement does not require that this due to/due from be settled in cash until liquidation of the Operating Partnership and therefore there is no regular settlement schedule for these amounts.

EARNINGS FROM DISCONTINUED OPERATIONS	EARNINGS FROM DISCONTINUED OPERATIONS In April 2014, the FASB issued ASU No. 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity . We adopted ASU 2014-08 during the period ending March 31, 2014. Due to the early adoption of ASU 2014-08, we did not classify Brookwood Mall, Colonial Village at North Arlington, Colonial Village at Vista Ridge, Greenbrook, Colonial Village at Inverness, Colonial Village at Charleston Place, Colonial Village at Huntleigh Woods, Colonial Village at Ashford Place or Colonial Promenade Huntsville, which were sold during 2014 , as discontinued operations. We also did not classify Vistas, Austin Chase, Fairways at Hartland, Fountain Lake, Post House Jackson, Post House North, Woodwinds, Oaks, Woods of Post House, Bradford Pointe, Huntington Chase, Westbury Creek, Colony at South Park, Paddock Park, Anatole, Bradford Chase, Sutton Place, Southland Station, Colonial Promenade Craft Farms, Colonial Grand Wilmington, Savannah Creek, or Whisperwood, which were sold during 2015, as discontinued operations. As part of the Merger on October 1, 2013, we acquired the Nord du Lac commercial property. Starting on October 1, 2013, the criteria for classifying this property as held for sale were met and as a result the assets and liabilities for this property were presented as held for sale in the Condensed Consolidated Balance Sheets , and the results of operations were included within discontinued operations in the Condensed Consolidated Statement of Operations for all periods presented through the period ended March 31, 2015. Additionally, we ceased recording depreciation and amortization following the held for sale designation. On May 29, 2015, after several amendments to the original sale agreement extending the closing date, the buyer elected not to purchase the property and consequently, the Nord Du Lac property no longer met the criteria to be classified as held for sale as of June 30, 2015. Approximately $34.1 million of real estate assets that were classified as held for sale as of March 31, 2015 was reclassified to held for use as of June 30, 2015, and included in the applicable line items in the accompanying Consolidated Balance Sheets. We also reclassified the balances in the Consolidated Balance Sheets as of December 31, 2014. We measured the property to be reclassified at the lower of (1) its carrying value before being classified as held for sale, adjusted for any depreciation and amortization expense that would have been recognized had the asset been continuously classified as held for use or (2) its fair value at the date of the subsequent decision not to sell. As a result of this reclassification, we recorded an additional $2.3 million of depreciation and amortization expense during the three months ended June 30, 2015, which represents the depreciation and amortization expense on the Nord du Lac property that would have been recognized had the property been continuously classified as held for use. Additionally, the related results of operations previously recorded in discontinued operations have been included in the applicable line items of continuing operations in the accompanying Consolidated Statements of Operations for all periods presented, and thus are not presented in discontinued operations in the tables below. One of the ten properties that we sold during 2014 , Willow Creek, as well as all nine properties sold during 2013 have been classified as discontinued operations in the accompanying Consolidated Statements of Operations. Willow Creek is included in discontinued operations because it had been designated as held for sale and was shown in discontinued operations as of December 31, 2013, and thus was not subject to ASU 2014-08. As a result of the adoption of ASU No. 2014-08, the Company did not report any discontinued operations for the year ended December 31, 2015. The following is a summary of income from continuing and discontinued operations attributable to MAA and noncontrolling interest for the years ended December 31, 2015 , 2014 and 2013 (dollars in thousands): 2015 2014 2013 Income from continuing operations: Attributable to MAA $ 332,287 $ 142,933 $ 36,539 Attributable to noncontrolling interest 18,458 8,013 1,153 Income from continuing operations $ 350,745 $ 150,946 $ 37,692 Income from discontinued operations: Attributable to MAA $ — $ 5,047 $ 78,742 Attributable to noncontrolling interest — 284 2,845 Income from discontinued operations $ — $ 5,331 $ 81,587 The following is a summary of earnings from discontinued operations for MAA for the years ended December 31, 2014 and 2013 (dollars in thousands): 2014 2013 Revenues: Rental revenues $ 75 $ 12,499 Other revenues 10 1,189 Total revenues 85 13,688 Expenses: Property operating expenses 74 5,886 Depreciation and amortization 42 2,716 Interest expense 32 436 Total expenses 148 9,038 Income from discontinued operations before gain on sale (63 ) 4,650 Net gain on insurance and other settlement proceeds on discontinued operations — 93 Gain on sale of discontinued operations 5,394 76,844 Income from discontinued operations $ 5,331 $ 81,587 The following is a summary of earnings from discontinued operations for MAALP for the years ended December 31, 2014 and 2013 (dollars in thousands): 2014 2013 Revenues: Rental revenues $ 75 $ 11,446 Other revenues 10 1,099 Total revenues 85 12,545 Expenses: Property operating expenses 74 5,390 Depreciation and amortization 42 2,480 Interest expense 32 436 Total expenses 148 8,306 Income from discontinued operations before gain on sale (63 ) 4,239 Net gain on insurance and other settlement proceeds on discontinued operations — 93 Gain on sale of discontinued operations 5,394 65,520 Income from discontinued operations $ 5,331 $ 69,852

Segment Information

Segment Information	12 Months Ended

Notes To Financial Statements [Abstract]
SEGMENT INFORMATION	SEGMENT INFORMATION As of December 31, 2015 , we owned or had an ownership interest in 254 multifamily apartment communities in 15 different states from which we derived all significant sources of earnings and operating cash flows. Senior management evaluates performance and determines resource allocations of each of our apartment communities on a Large Market Same Store, Secondary Market Same Store, and Non-Same Store and Other basis, as well as an individual apartment community basis. This is consistent with the aggregation criteria under GAAP as each of our apartment communities generally has similar economic characteristics, facilities, services, and tenants. The following are the three reportable operating segments for MAA and the Operating Partnership: • Large market same store communities are generally communities in markets with a population of at least 1 million and at least 1% of the total public multifamily REIT units that we have owned and have been stabilized for at least a full 12 months. • Secondary market same store communities are generally communities in markets with populations of more than 1 million but less than 1% of the total public multifamily REIT units or markets with populations of less than 1 million that we have owned and have been stabilized for at least a full 12 months. • Non same store communities and other includes recent acquisitions, communities in development or lease-up, communities that have been identified for disposition, and communities that have undergone a significant casualty loss. Also included in non same store communities are non multifamily activities which represent less than 1% of our portfolio. On the first day of each calendar year, we determine the composition of our same store operating segments for that year as well as adjusting the previous year, which allows us to evaluate full period-over-period operating comparisons. Properties in development or lease-up will be added to the same store portfolio on the first day of the calendar year after they have been owned and stabilized for at least a full 12 months. Communities are considered stabilized after achieving 90% occupancy for 90 days . Communities that have been identified for disposition are excluded from our same store portfolio. We utilize net operating income, or NOI, in evaluating the performance of the segments. Total NOI represents total property revenues less total property operating expenses, excluding depreciation and amortization, for all properties held during the period regardless of their status as held for sale. We believe NOI is a helpful tool in evaluating the operating performance of our segments because it measures the core operations of property performance by excluding corporate level expenses and other items not related to property operating performance. A redevelopment community is a community with a specific plan in place to upgrade at least half of the community's units over a period of time with new finishes, fixtures, and appliances, among other upgrades. These plans include spending a pre-defined amount of capital per unit to achieve a rent increase as a result of the upgrades. We separately identify redevelopment communities that would cause a material distortion of normal same store operating results. Routine renovations occur at a property as items need to be replaced as a normal part of operations and is done with an expectation to maintain the current level of quality at the property. There is no specified plan in place for routine renovations. Revenues and NOI for each reportable segment for the years ended December 31, 2015 , 2014 and 2013 were as follows (dollars in thousands): 2015 2014 2013 (1) Revenues Large Market Same Store $ 587,896 $ 553,038 $ 241,194 Secondary Market Same Store 324,771 310,281 242,464 Non-Same Store and Other 130,112 128,859 151,185 Total property revenues 1,042,779 992,178 634,843 Management fee income — 154 647 Total operating revenues $ 1,042,779 $ 992,332 $ 635,490 NOI Large Market Same Store $ 361,285 $ 334,255 $ 142,988 Secondary Market Same Store 200,989 190,348 147,607 Non-Same Store and Other 79,860 74,211 98,417 Total NOI 642,134 598,814 389,012 Discontinued operations NOI included above — 16 (7,802 ) Management fee income — 154 647 Depreciation and amortization (294,520 ) (301,812 ) (186,979 ) Acquisition expense (2,777 ) (2,388 ) (1,393 ) Property management expense (30,990 ) (32,095 ) (23,083 ) General and administrative expense (25,716 ) (20,909 ) (15,569 ) Merger related expenses — (3,152 ) (32,403 ) Integration costs — (8,395 ) (5,102 ) Interest and other non-property (expense) income (368 ) 770 466 Interest expense (122,344 ) (123,953 ) (78,978 ) Loss on debt extinguishment/modification (3,602 ) (2,586 ) (426 ) Net casualty (loss) gain after insurance and other settlement proceeds 473 (476 ) (143 ) Gain on sale of depreciable real estate assets excluded from discontinued operations 189,958 42,649 — Income tax expense (1,673 ) (2,050 ) (893 ) Gain on sale of non-depreciable real estate assets 172 350 — (Loss) gain from real estate joint ventures (2 ) 6,009 338 Discontinued operations — 5,331 81,587 Net income attributable to noncontrolling interests (18,458 ) (8,297 ) (3,998 ) Net income available to MAA common shareholders $ 332,287 $ 147,980 $ 115,281 (1) The 2013 column shows the segment break down based on the 2014 same store portfolios.

Accounting Policies [Abstract]
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation The accompanying consolidated financial statements have been prepared by our management in accordance with United States generally accepted accounting principles, or GAAP, and applicable rules and regulations of the Securities and Exchange Commission, or the SEC. The consolidated financial statements of MAA presented herein include the accounts of MAA, the Operating Partnership, and all other subsidiaries in which MAA has a controlling financial interest. MAA owns approximately 95% to 100% of all consolidated subsidiaries. The consolidated financial statements of MAALP presented herein include the accounts of MAALP and all other subsidiaries in which MAALP has a controlling financial interest. MAALP owns, directly or indirectly, 100% of all consolidated subsidiaries. In our opinion, all adjustments necessary for a fair presentation of the consolidated financial statements have been included, and all such adjustments were of a normal recurring nature. All significant intercompany accounts and transactions have been eliminated in consolidation. We invest in entities which may qualify as variable interest entities, or VIE. A VIE is a legal entity in which the equity investors lack sufficient equity at risk for the entity to finance its activities without additional subordinated financial support or, as a group, the holders of the equity investment at risk lack the power to direct the activities of a legal entity as well as the obligation to absorb its expected losses or the right to receive its expected residual returns. We consolidate all VIEs for which we are the primary beneficiary and use the equity method to account for investments that qualify as VIEs but for which we are not the primary beneficiary. In determining whether we are the primary beneficiary of a VIE, we consider qualitative and quantitative factors, including but not limited to, those activities that most significantly impact the VIE's economic performance and which party controls such activities. We use the equity method of accounting for our investments in entities for which we exercise significant influence, but do not have the ability to exercise control. These entities are not variable interest entities. The factors considered in determining that we do not have the ability to exercise control include ownership of voting interests and participatory rights of investors.
Use of Estimates	Use of Estimates Management has made a number of estimates and assumptions relating to the reporting of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of revenues and expenses to prepare these financial statements and notes in conformity with GAAP. Actual results could differ from those estimates.
Revenue Recognition and Real Estate Sales	Revenue Recognition and Real Estate Sales We primarily lease multifamily residential apartments under operating leases generally with terms of one year or less. Rental revenues are recognized using a method that represents a straight-line basis over the term of the lease and other revenues are recorded when earned. Rental income represents gross market rent less adjustments for concessions, vacancy loss and bad debt. We record gains and losses on real estate sales in accordance with accounting standards governing the sale of real estate. For sale transactions meeting the requirements for the full accrual method, we remove the assets and liabilities from our Consolidated Balance Sheets and record the gain or loss in the period the transaction closes.
Rental Costs	Rental Costs Costs associated with rental activities, including advertising costs, are expensed as incurred. Advertising expenses were approximately $13.5 million , $12.4 million , and $9.5 million for the years ended December 31, 2015 , 2014 , and 2013 , respectively.
Discontinued Operations	Discontinued Operations Prior to our January 2014 adoption of ASU No. 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity, properties sold during the year or those classified as held-for-sale at the end of a reporting period were classified as discontinued operations in accordance with accounting standards governing financial statement presentation. Subsequent to our adoption of this ASU on January 1, 2014, only dispositions representing significant changes in operating strategy are classified as discontinued operations. Once a property is classified as held-for-sale, depreciation is no longer recognized.
Real Estate Assets and Depreciation and Amortization	Real Estate Assets and Depreciation and Amortization Real estate assets are carried at depreciated cost. Repairs and maintenance costs are expensed as incurred while significant improvements, renovations, and recurring capital replacements are capitalized. Recurring capital replacements typically include scheduled carpet replacement, new roofs, HVAC units, plumbing, concrete, masonry and other paving, pools and various exterior building improvements. In addition to these costs, we also capitalize salary costs directly identifiable with renovation work. These expenditures extend the useful life of the property and increase the property’s fair market value. The cost of interior painting, vinyl flooring and blinds are expensed as incurred. Depreciation is computed on a straight-line basis over the estimated useful lives of the related assets which range from 8 to 40 years for land improvements and buildings, 5 years for furniture, fixtures and equipment, and 3 to 5 years for computers and software.
Development Costs	Development Costs Development projects and the related carrying costs, including interest, property taxes, insurance and allocated direct development salary cost during the construction period, are capitalized and reported in the accompanying Consolidated Balance Sheets as “Development and capital improvements in progress” during the construction period. Interest is capitalized in accordance with accounting standards governing the capitalization of interest. Upon completion and certification for occupancy of individual buildings within a development, amounts representing the completed building's portion of total estimated development costs for the project are transferred to "Land", "Buildings", and "Furniture, fixtures and equipment" as real estate held for investment. Capitalization of interest, property taxes, insurance and allocated direct development salary costs cease upon the transfer. The assets are depreciated over their estimated useful lives. Total interest capitalized during the years ended December 31, 2015 , 2014 and 2013 was approximately $1.7 million , $1.7 million , and $2.1 million , respectively. Indirect costs other than interest that we capitalized included capitalized salaries of $0.4 million , $1.7 million , and $0.4 million during the years ended December 31, 2015 , 2014 and 2013 , respectively, and real estate taxes of $0.2 million , $0.2 million , and $0.3 million during the years ended December 31, 2015 , 2014 and 2013 , respectively. Certain costs associated with the lease-up of development projects, including cost of model units, their furnishings, signs, and “grand openings,” are capitalized and amortized over their respective estimated useful lives. All other costs relating to renting development projects are expensed as incurred.
Acquisition of Real Estate Assets	Acquisition of Real Estate Assets In accordance with accounting standards for business combinations, the fair value of the real estate acquired is allocated to the acquired tangible assets, consisting of land, building, furniture, fixtures and equipment, and identified intangible assets, consisting of the value of in-place leases and other contracts. We allocate the purchase price to the fair value of the tangible assets of an acquired property determined by valuing the building as if it were vacant, based on management’s determination of the relative fair values of these assets. Management determines the as-if-vacant fair value of a building using methods similar to those used by independent appraisers. These methods include using stabilized net operating income, or NOI, and market specific capitalization and discount rates. In allocating the fair value of identified intangible assets of an acquired property, the in-place leases are valued based on current rent rates and time and cost to lease a unit. Management concluded that the residential leases acquired in connection with each of its property acquisitions are approximately at market rates since the residential lease terms generally do not extend beyond one year. For larger, portfolio style acquisitions, like the Merger, management engages a third party valuation specialist to perform the fair value assessment, which includes an allocation of the purchase price. Similar to management's methods, the third party uses cash flow analysis as well as an income approach and a market approach to determine the fair value of assets. The third party uses stabilized NOI and market specific capitalization and discount rates. Management reviews the inputs used by the third party specialist as well as the allocation of the purchase price provided by the third party to ensure reasonableness and that the procedures are performed in accordance with management's policy. The initial allocation of the purchase price is based on management’s preliminary assessment, which may differ when final information becomes available. Subsequent adjustments made to the initial purchase price allocation, if any, are made within the allocation period, which typically does not exceed one year. For residential leases, the fair value of the in-place leases and resident relationships is then amortized over 6 months, the estimated remaining term of the resident leases. For commercial leases, the fair value of in-place leases and resident relationships is amortized over the remaining term of the commercial leases. The amount of lease intangibles included in Other assets totaled $6.1 million , $8.3 million , and $54.0 million as of December 31, 2015 , 2014 , and 2013 , respectively. Accumulated amortization for these leases totaled $2.3 million , $1.8 million , and $21.9 million as of December 31, 2015 , 2014 and 2013 , respectively. The amortization recorded as depreciation and amortization expense was $5.0 million , $24.5 million , and $23.5 million for the years ended December 31, 2015 , 2014 , and 2013 , respectively. The estimated aggregate future amortization expense is approximately $1.4 million , $0.5 million , $0.4 million , $0.3 million , and $0.3 million for the years ended December 31, 2016, 2017, 2018, 2019, and 2020, respectively. The Company's policy is to expense the costs incurred to acquire properties in the period these costs are incurred. Acquisition costs include appraisal fees, title fees, broker fees, and other legal costs to acquire the property. These costs are recorded in our Consolidated Statement of Operations under the line "Acquisition expenses".
Impairment of Long-lived Assets, including Goodwill	Impairment of Long-lived Assets, including Goodwill We account for long-lived assets in accordance with the provisions of accounting standards for the impairment or disposal of long-lived assets and evaluate our goodwill for impairment under accounting standards for goodwill and other intangible assets. We evaluate goodwill for impairment on at least an annual basis, or more frequently if a goodwill impairment indicator is identified. We periodically evaluate long-lived assets, including investments in real estate and goodwill, for indicators that would suggest that the carrying amount of the assets may not be recoverable. The judgments regarding the existence of such indicators are based on factors such as operating performance, market conditions and legal factors. Long-lived assets, such as real estate assets, equipment and purchased intangibles subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized for the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of are separately presented on the Balance Sheet and reported at the lower of the carrying amount or fair value less costs to sell, and are no longer depreciated. The assets and liabilities of a disposed group or a property classified as held for sale are presented separately in the appropriate asset and liability sections of the balance sheet. Goodwill is tested annually for impairment and is tested for impairment more frequently if events and circumstances indicate that the asset might be impaired. An impairment loss for goodwill is recognized to the extent that the carrying amount exceeds the implied fair value of goodwill. This determination is made at the reporting unit level and consists of two steps. First, we determine the fair value of a reporting unit and compare it to its carrying amount. In the apartment industry, the primary method used for determining fair value is to divide annual operating cash flows by an appropriate capitalization rate. We determine the appropriate capitalization rate by reviewing the prevailing rates in a property’s market or submarket. Second, if the carrying amount of a reporting unit exceeds its fair value, an impairment loss is recognized for any excess of the carrying amount of the reporting unit’s goodwill over the implied fair value of that goodwill. The implied fair value of goodwill is determined by allocating the fair value of the reporting unit in a manner similar to a purchase price allocation in accordance with accounting standards for business combinations. The residual fair value after this allocation is the implied fair value of the reporting unit goodwill. There has been no impairment of goodwill in the three year period ended December 31, 2015 .
Loss Contingencies	Loss Contingencies The outcomes of claims, disputes and legal proceedings are subject to significant uncertainty. We record an accrual for loss contingencies when a loss is probable and the amount of the loss can be reasonably estimated. We review these accruals quarterly and make revisions based on changes in facts and circumstances. When a loss contingency is not both probable and reasonably estimable, we do not accrue the loss. However, if the loss (or an additional loss in excess of the accrual) is at least a reasonable possibility and material, then we disclose a reasonable estimate of the possible loss, or range of loss, if such reasonable estimate can be made. If we cannot make a reasonable estimate of the possible loss, or range of loss, then a statement to that effect is disclosed. The assessment of whether a loss is probable or a reasonable possibility, and whether the loss or range of loss is reasonably estimable, often involves a series of complex judgments about future events. Among the factors that we consider in this assessment, are the nature of existing legal proceedings and claims, the asserted or possible damages or loss contingency (if reasonably estimable), the progress of the matter, existing law and precedent, the opinions or views of legal counsel and other advisers, our experience in similar matters, the facts available to us at the time of assessment, and how we intend to respond, or have responded, to the proceeding or claim. Our assessment of these factors may change over time as individual proceedings or claims progress. For matters where we are not currently able to reasonably estimate a range of reasonably possible loss, the factors that have contributed to this determination include the following: (i) the damages sought are indeterminate; (ii) the proceedings are in the early stages; (iii) the matters involve novel or unsettled legal theories or a large or uncertain number of actual or potential cases or parties; and/or (iv) discussions with the parties in matters that are expected ultimately to be resolved through negotiation and settlement have not reached the point where we believe a reasonable estimate of loss, or range of loss, can be made. In such instances, we believe that there is considerable uncertainty regarding the timing or ultimate resolution of such matters, including a possible eventual loss or business impact, if any.
Undeveloped Land	Undeveloped Land Undeveloped land includes sites intended for future multifamily developments, sites for future commercial development and sites intended for residential use, which are carried at the lower of cost or fair value in accordance with GAAP and any costs incurred prior to commencement of pre-development activities are expensed as incurred.
Investment in Real Estate Joint Ventures	Investment in Real Estate Joint Ventures Our investments in our unconsolidated real estate joint ventures are recorded using the equity method as we are able to exert significant influence, but do not have a controlling interest in any of our joint ventures.
Cash and Cash Equivalents	Cash and Cash Equivalents We consider investments in money market accounts and certificates of deposit with original maturities of three months or less to be cash equivalents.
Restricted Cash	Restricted Cash Restricted cash consists of security deposits required to be held separately, escrow deposits held by lenders for property taxes, insurance, debt service, and replacement reserves, and exchanges under Section 1031(b) of the Internal Revenue Code of 1986, as amended, or the Code. Section 1031(b) exchanges are treated as investing activities in the Consolidated Statement of Cash Flows.
Deferred Financing Costs	Deferred Financing Costs Deferred financing costs are amortized over the terms of the related debt using a method which approximates the effective interest method. If the terms of renewed or modified debt instruments are deemed to be substantially different, all unamortized financing costs associated with the modified debt are charged to earnings in the current period. If the terms are not substantially different, the costs associated with the renewal are capitalized and amortized over the remaining term of the debt instrument. For modifications affecting a line of credit, fees paid to a creditor and any third party costs will be capitalized and amortized over the remaining term of the new arrangement. Any unamortized deferred financing costs associated with the old arrangement are either deferred and amortized over the life of the new arrangement or written off, depending upon the nature of the modification and cost. The balance of any unamortized financing costs on extinguished debt is expensed upon extinguishment.
Other Assets	Other Assets Other assets consist primarily of deferred rental concessions which are recognized on a straight line basis over the life of the leases, receivables and deposits from residents, the value of derivative contracts and other prepaid expenses including prepaid insurance and prepaid interest. Also included in other assets are the fair market value of in place leases, which totaled $6.1 million and $8.3 million as of December 31, 2015 and 2014 , respectively.
Accrued Expenses and Other Liabilities	Accrued Expenses and Other Liabilities Accrued expenses consist of accrued dividends payable, accrued real estate taxes, accrued interest payable, other accrued expenses payable, and unearned income. Significant accruals include accrued dividends payable of $65.2 million and $61.2 million at December 31, 2015 and 2014 , respectively, accrued real estate taxes of $63.3 million and $56.8 million at December 31, 2015 and 2014 , respectively, and accrued interest payable of $17.2 million and $17.8 million , at December 31, 2015 and 2014 , respectively.
Self Insurance	Self-Insurance We are self-insured for workers' compensation claims up to $500,000 and for general liability claims up to $100,000 . Claims exceeding these amounts are insured by a third party. We accrue for expected liabilities less than $500,000 for workers' compensation based on a third party actuarial estimate of ultimate losses and we also accrue for expected general liability claims less than $100,000 based on a third party actuarial estimate of ultimate losses.
Income Taxes	Income Taxes MAA has elected to be taxed as a REIT under the Code, beginning with the taxable year ended December 31, 1994, and intends to continue to operate in such a manner. The current and continuing qualification as a REIT depends on MAA's ability to meet the various requirements imposed by the Code, which are related to organizational structure, distribution levels, diversity of stock ownership and certain restrictions with regard to owned assets and categories of income. As long as MAA qualifies for taxation as a REIT, it will generally not be subject to United States Federal corporate income tax on its taxable income that is currently distributed to shareholders. This treatment substantially eliminates the “double taxation” (at the corporate and shareholder levels) that generally results from an investment in a corporation. Even if MAA qualifies as a REIT, it may be subject to United States Federal income and excise taxes in certain situations, such as not meeting the income distribution requirements. MAA also will be required to pay a 100% tax on any net income on non-arm’s length transactions between MAA and its Taxable REIT Subsidiaries, or TRS (discussed below). In addition, MAA could also be subject to the alternative minimum tax, or AMT. State and local tax laws may not conform to the United States Federal income tax treatment, and MAA and its shareholders may be subject to state or local taxation in various state or local jurisdictions, including those in which MAA transacts business or its shareholders reside. Any taxes imposed on MAA would reduce its operating cash flow and net income. Certain of our operations or a portion thereof, including asset management and risk management, are conducted through TRSs, which are subsidiaries of the Operating Partnership. A TRS is a C-corporation that has not elected REIT status and as such is subject to United States Federal corporate income tax. The TRS accounts for deferred taxes by recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements or tax returns. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. A valuation allowance is provided when it is more likely than not that some portion or all of the deferred tax assets will not be realized. Based on this evaluation, at December 31, 2015 , net of the valuation allowance, the net deferred tax assets were reduced to zero. The Company recognizes liabilities for uncertain income tax positions based on a two-step process. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step requires the Company to estimate and measure the tax benefit as the largest amount that is more than 50% likely to be realized upon ultimate settlement. The Company classifies interest related to income tax liabilities, and if applicable, penalties, as a component of Income tax expense. As of December 31, 2015 , we did not have any unrecognized tax benefits, and we do not believe that there will be any material changes in our unrecognized tax positions over the next 12 months. The income tax expense line item shown in the Statement of Operations represents the Texas-based margin tax for all Texas properties.
Fair value of derivative financial instruments	Fair value of derivative financial instruments We utilize certain derivative financial instruments, primarily interest rate swaps and interest rate caps, during the normal course of business to manage, or hedge, the interest rate risk associated with our variable rate debt or as hedges in anticipation of future debt transactions to manage well-defined interest rate risk associated with the transaction. In order for a derivative contract to be designated as a hedging instrument, changes in the hedging instrument must be highly effective at offsetting changes in the hedged item. The historical correlation of the hedging instruments and the underlying hedged items are assessed before entering into the hedging relationship and on a quarterly basis thereafter, and have been found to be highly effective. We measure ineffectiveness using the change in the variable cash flows method or the hypothetical derivative method for interest rate swaps and the hypothetical derivative method for interest rate caps for each reporting period through the term of the hedging instruments. Any amounts determined to be ineffective are recorded in earnings if in an overhedged position. The change in fair value of the interest rate swaps and the intrinsic value or fair value of interest rate caps designated as cash flow hedges are recorded to accumulated other comprehensive income in the Statement of Equity. The valuation of our derivative financial instruments is determined using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each derivative. The fair values of interest rate swaps are determined using the market standard methodology of netting the discounted future fixed cash payments and the discounted expected variable cash receipts. The variable cash receipts are based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves. The fair values of interest rate caps are determined using the market standard methodology of discounting the future expected cash receipts that would occur if variable interest rates rise above the strike rate of the interest rate caps. The variable interest rates used in the calculation of projected receipts on the interest rate cap are based on an expectation of future interest rates derived from observable market interest rate curves and volatilities. Additionally, we incorporate credit valuation adjustments to appropriately reflect both our own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. Changes in the fair values of our derivatives are primarily the result of fluctuations in interest rates. See Note 7 (Derivative and Hedging Activities) and Note 8 (Fair Value Disclosure of Financial Information) for further discussion.
Recent Accounting Pronouncements	Recent Accounting Pronouncements The following table provides a brief description of recent accounting pronouncements that could have a material effect on our financial statements: Standard Description Date of Adoption Effect on the Financial Statements or Other Significant Matters Accounting Standards Update (ASU) 2015-03 and ASU 2015-15, Interest -Imputation of Interest ASU 2015-03, requires that debt issuance costs be presented in the balance sheet as a direct deduction from the carrying amount of debt liability, consistent with debt discounts or premiums. ASU 2015-15 provides additional guidance to ASU 2015-03, which did not address presentation or subsequent measurement of debt issuance costs related to line-of-credit arrangements. ASU 2015-15 noted that the SEC staff would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. This ASU is effective for annual periods ending after December 15, 2015; however, early adoption is permitted. We adopted this ASU on December 31, 2015. The adoption of this ASU resulted in the reclassification of $13.3 million and $11.8 million of unamortized debt issuance costs related to the company’s secured property mortgages, senior unsecured notes, and unsecured term loans from Deferred financing costs, net to a reduction in Unsecured and Secured notes payable within its Consolidated Balance Sheets as of December 31, 2015 and 2014, respectively. ASU 2014-15, Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern This ASU requires an entity's management to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity's ability to continue as a going concern within one year after the date that the financial statements are issued. If substantial doubt exists, the entity must disclose the principal conditions or events that raised the substantial doubt, management's evaluation of the significance of these conditions, and management's plan for alleviating the substantial doubt about the entity's ability to continue as a going concern. This ASU is effective for annual periods ending after December 15, 2016; however, early adoption is permitted. We are currently in the process of evaluating the impact of this ASU, but we do not expect the adoption of this ASU to have a material impact on our consolidated financial position or results of operations taken as a whole. ASU 2014-09, Revenue from Contracts with Customers This ASU establishes principles for recognizing revenue upon the transfer of promised goods or services to customers, in an amount that reflects the expected consideration received in exchange for those goods or services. This ASU is effective for annual reporting periods beginning after December 15, 2017, as a result of a deferral of the effective date arising from the issuance of ASU 2015-14, Revenue from Contracts with Customers - Deferral of the Effective Date. Early adoption is permitted. The amendments may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of initial application. We are currently in the process of evaluating the impact of adoption of this ASU on our consolidated financial condition and results of operations taken as a whole and plan on completing this assessment in the fourth quarter of 2016, but we do not expect the impact to be material. We have not yet determined which method will be used for initial application. ASU 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity This ASU raises the threshold for disposals to qualify as discontinued operations. It also requires additional disclosures for discontinued operations and new disclosures for individually material disposal transactions that do not meet the definition of a discontinued operation. This ASU is effective for fiscal years beginning after December 15, 2014, and interim periods within those years; however, early adoption is permitted beginning in the first quarter of 2014. We adopted this ASU on January 1, 2014. The adoption of this ASU required us to not classify certain disposals occurring during 2014 as discontinued operations. The 2014 dispositions did not qualify for discontinued operations treatment and therefore the gains on these properties are presented as a component of continuing operations for 2014.

Earnings per share of the trust [Abstract]
Schedule of Calculation of Numerator and Denominator in Earnings Per Share [Table Text Block]	Basic earnings per share is computed by dividing net income available to MAA common shareholders by the weighted average number of shares outstanding during the period. All outstanding unvested restricted share awards contain rights to non-forfeitable dividends and participate in undistributed earnings with common shareholders and, accordingly, are considered participating securities that are included in the two-class method of computing basic earnings per share. Both the unvested restricted shares and other potentially dilutive common shares, and the related impact to earnings, are considered when calculating earnings per share on a diluted basis with our diluted earnings per share being the more dilutive of the treasury stock or two-class methods. Operating partnership units are included in dilutive earnings per share calculations when they are dilutive to earnings per share. For the years ended December 31, 2015 , 2014 , and 2013 , MAA's basic earnings per share is computed using the two-class method, and our diluted earnings per share is computed using the more dilutive of the treasury stock method or two-class method: (dollars and shares in thousands, except per share amounts) Years ended December 31, 2015 2014 2013 Shares Outstanding Weighted average common shares - basic 75,176 74,982 50,677 Weighted average partnership units outstanding — (1) — (1) 2,351 Effect of dilutive securities — (2) — (2) 88 Weighted average common shares - diluted 75,176 74,982 53,116 Calculation of Earnings per Share - basic Income from continuing operations $ 350,745 $ 150,946 $ 37,692 Income from continuing operations attributable to noncontrolling interests (18,458 ) (8,013 ) (1,154 ) Income from continuing operations allocated to unvested restricted shares (772 ) (278 ) (34 ) Income from continuing operations available for common shareholders, adjusted $ 331,515 $ 142,655 $ 36,504 Income from discontinued operations $ — $ 5,331 $ 81,587 Income from discontinued operations attributable to noncontrolling interest — (284 ) (2,845 ) Income from discontinued operations allocated to unvested restricted shares — (10 ) (73 ) Income from discontinued operations available for common shareholders, adjusted $ — $ 5,037 $ 78,669 Weighted average common shares - basic 75,176 74,982 50,677 Earnings per share - basic $ 4.41 $ 1.97 $ 2.27 Calculation of Earnings per Share - diluted Income from continuing operations $ 350,745 $ 150,946 $ 37,692 Income from continuing operations attributable to noncontrolling interests (18,458 ) (1) (8,013 ) (1) — Income from continuing operations allocated to unvested restricted shares (772 ) (2) (278 ) (2) — Income from continuing operations available for common shareholders, adjusted $ 331,515 $ 142,655 $ 37,692 Income from discontinued operations $ — $ 5,331 $ 81,587 Income from discontinued operations attributable to noncontrolling interest — (1) (284 ) (1) — Income from discontinued operations allocated to unvested restricted shares — (2) (10 ) (2) — Income from discontinued operations available for common shareholders, adjusted $ — $ 5,037 $ 81,587 Weighted average common shares - diluted 75,176 74,982 53,116 Earnings per share - diluted $ 4.41 $ 1.97 $ 2.25 (1) For both the years ended December 31, 2015 and 2014, 4.2 million OP units and their related income are not included in the diluted earnings per share calculations as they are not dilutive.
