Consolidation And Basis Of Presentation And Significant Accounting Policies [Abstract]
Organization and Summary of Significant Accounting Policies	1. Organization and Summary of Significant Accounting Policies Unless the context otherwise requires, all references to the “Company” refer collectively to Mid-America Apartment Communities, Inc., together with its consolidated subsidiaries, including Mid-America Apartments, L.P. Unless the context otherwise requires, all references to “MAA” refer only to Mid-America Apartment Communities, Inc., and not any of its consolidated subsidiaries. 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, “preferred stock” refers to the preferred stock of MAA, and “shareholders” refers to the holders of shares of MAA’s common stock or preferred stock, as applicable. The common units of limited partnership interests in the Operating Partnership are referred to as “OP Units,” and the holders of the OP Units are referred to as “common unitholders.” As of December 31, 2023, MAA owned 116,694,124 OP Units (or 97.4 % of the total number of OP Units). MAA conducts substantially all of its business and holds substantially all of its assets, directly or indirectly, 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. Management believes combining the notes to the consolidated financial statements of MAA and the Operating Partnership 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; and • creates time and cost efficiencies through the preparation of one combined set of notes instead of two separate sets. MAA, an S&P 500 company, is a multifamily-focused, self-administered and self-managed real estate investment trust, or REIT. 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. Management believes 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 partnership interests in the Operating Partnership (other than cash held by MAA from time to time); therefore, MAA’s primary function is 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 from time to time. The Operating Partnership holds, directly or indirectly, all of the Company’s real estate assets. Except for net proceeds from public equity issuances by MAA, which are contributed to the Operating Partnership in exchange for limited partnership interests, the Operating Partnership generates the capital required by the business through the Operating Partnership’s operations, direct or indirect incurrence of indebtedness and issuance of OP Units. The presentations 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 interests, treasury shares, accumulated other comprehensive income or loss and redeemable common stock. The Operating Partnership’s capital may include common capital and preferred capital of the general partner (MAA), limited partners’ common capital and preferred capital, noncontrolling interests, accumulated other comprehensive income or loss and redeemable common units. Holders of OP Units (other than MAA) may require the Operating Partnership to redeem their OP Units from time to time, in which case the Operating Partnership may, at its 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, or NYSE, over a specified period prior to the redemption date) or by delivering one share of MAA’s common stock (subject to adjustment under specified circumstances) for each OP Unit so redeemed. Organization of Mid-America Apartment Communities, Inc. The Company owns, operates, acquires and selectively develops apartment communities primarily located in the Southeast, Southwest and Mid-Atlantic regions of the U.S. As of December 31, 2023, the Company owned and operated 290 apartment communities (which does not include development communities under construction) through the Operating Partnership and its subsidiaries and had an ownership interest in one apartment community through an unconsolidated real estate joint venture. As of December 31, 2023, the Company also had five development communities under construction, totaling 1,970 apartment units once complete, and $ 391.6 million had been incurred through December 31, 2023 . The Company expects to complete three of these developments in 2024 and two in 2025. As of December 31, 2023, 34 of the Company’s apartment communities included retail components. The Company’s apartment communities, including development communities under construction, were located across 16 states and the District of Columbia as of December 31, 2023. Basis of Presentation and Principles of Consolidation The accompanying consolidated financial statements have been prepared by the Company’s management in accordance with U.S. 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, directly or indirectly, approximately 80 % to 100 % of all consolidated subsidiaries, including the Operating Partnership. In management’s 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. The Company invests in entities that may qualify as variable interest entities, or VIEs, and MAALP is considered a 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. MAALP is classified as a VIE because the limited partners lack substantive kick-out rights and substantive participating rights, and the Company is its primary beneficiary. The Company consolidates all VIEs for which it is the primary beneficiary and uses the equity method to account for investments that qualify as VIEs but for which it is not the primary beneficiary. In determining whether the Company is the primary beneficiary of a VIE, management considers both 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. The Company uses the equity method of accounting for its investments in entities for which the Company exercises significant influence but does not have the ability to exercise control. The factors considered in determining whether the Company has the ability to exercise significant influence or control include ownership of voting interests and participatory rights of investors (see “Investments in Unconsolidated Affiliates” below). Noncontrolling Interests As of December 31, 2023, the Company had two types of noncontrolling interests with respect to its consolidated subsidiaries: (1) noncontrolling interests related to the common unitholders of its Operating Partnership; and (2) noncontrolling interests related to its consolidated real estate entities. The noncontrolling interests relating to the limited partnership interests in the Operating Partnership are owned by the holders of the Class A OP Units. MAA is the sole general partner of the Operating Partnership and holds all of the outstanding Class B OP Units. Net income (after allocations to preferred ownership interests) is allocated to MAA and the noncontrolling interests based on their respective ownership percentages of the Operating Partnership. Issuance of additional Class A OP Units or Class B OP Units changes the ownership percentage of both the noncontrolling interests and MAA. The issuance of Class B OP Units generally occurs when MAA issues common stock and the issuance proceeds are contributed to the Operating Partnership in exchange for Class B OP Units equal to the number of shares of MAA’s common stock issued. At each reporting period, the allocation between total MAA shareholders’ equity and noncontrolling interests 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 OP Unit that were equivalent to the economic rights in respect to each share of MAA common stock. See Note 9 for additional details. The noncontrolling interests relating to the Company’s consolidated real estate entities are owned by private real estate companies that are generally responsible for the development, construction and lease-up of the apartment communities that are owned through the consolidated real estate entities with a noncontrolling interest. The entities were determined to be VIE’s with the Company designated as the primary beneficiary. As a result, the accounts of the entities are consolidated by the Company. As of December 31, 2023, the consolidated assets of the Company’s consolidated real estate entities with a noncontrolling interest were $ 265.1 million , and consolidated liabilities were $ 12.9 million . As of December 31, 2022, the consolidated assets of the Company’s consolidated real estate entities with a noncontrolling interest were $ 279.6 million , and consolidated liabilities were $ 14.5 million . During the years ended December 31, 2023 and 2022 , the Company paid $ 15.8 million and $ 43.1 million, respectively, to acquire the noncontrolling interest of a consolidated real estate entity. Real Estate Assets and Depreciation and Amortization Real estate assets are carried at depreciated cost and consist of land, buildings and improvements and other, and development and capital improvements in progress (see “Development Costs” below). Repairs and maintenance costs are expensed as incurred, while significant improvements, renovations and recurring capital replacements are capitalized and depreciated over their estimated useful lives. 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, the Company also capitalizes 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 and blinds are typically expensed as incurred. Depreciation is computed on a straight-line basis over the estimated useful lives of the related assets, which range from three to 40 years. The line item “Buildings and improvements and other” in the Consolidated Balance Sheets includes land improvements and buildings, which have a useful life ranging from five to 40 years , as well as furniture, fixtures and equipment, which have a useful life of three to five years. Development Costs Development projects and the related carrying costs, including interest, property taxes, insurance and allocated direct development salary costs 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 or floors within a development, amounts representing the completed portion of total estimated development costs for the project are transferred to “Buildings and improvements and other” 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 capitalized costs (including capitalized interest, property taxes, insurance and salaries) during the years ended December 31, 2023, 2022 and 2021 were $ 20.6 million , $ 14.4 million and $ 16.6 million , respectively. Certain costs associated with the lease-up of development projects, including cost of model units, furnishings and signs, 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 Codification, or ASC, Topic 805, Business Combinations , most acquisitions of operating properties qualify as an asset acquisition. Accordingly, the cost of the real estate acquired, including acquisition costs, is allocated to the acquired tangible assets, consisting of land, buildings and improvements and other, and identified intangible assets, consisting of the value of in-place leases and other contracts, on a relative fair value basis. Acquisition costs include appraisal fees, title fees, broker fees and other legal costs to acquire the property. The purchase price of an acquired property is allocated based on the relative fair value of the individual components as a proportion of the total assets acquired. The Company allocates the cost of the tangible assets of an acquired property 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. The Company allocates the cost of land based on its relative fair value if acquired with a multifamily community or records the value based on the purchase price paid if acquired separately. In allocating the cost 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 approximate at-market rates since the residential lease terms generally do not extend beyond one year. For residential leases, the fair value of the in-place leases and resident relationships is amortized over the remaining term of the resident leases. For retail and commercial leases, the fair value of in-place leases and tenant relationships is amortized over the remaining term of the leases. The net amount of these lease intangibles included in “Other assets” totaled $ 1.6 million and $ 0.8 million as of December 31, 2023 and 2022 , respectively. Impairment of Long-lived Assets The Company accounts for long-lived assets in accordance with the provisions of accounting standards for the impairment or disposal of long-lived assets. Management periodically evaluates long-lived assets, including investments in real estate, 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 future undiscounted 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 in the appropriate asset and liability sections in the Consolidated Balance Sheets, are reported at the lower of the carrying amount or fair value less costs to sell and are no longer depreciated. Undeveloped Land Undeveloped land includes sites intended for future multifamily developments and sites for future commercial development, which are carried at cost and evaluated for impairment when indicators are present. Any costs incurred prior to commencement of pre-development activities are expensed as incurred. Cash and Cash Equivalents Investments in money market accounts and certificates of deposit with original maturities of three months or less are considered 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 cash held for exchanges under Section 1031(b) of the Internal Revenue Code of 1986, as amended, or the Code. Section 1031(b) exchanges are presented within “Cash, cash equivalents and restricted cash” in the accompanying Consolidated Statements of Cash Flows. Investments in Unconsolidated Affiliates The Company uses the equity method to account for its investments in a real estate joint venture and six technology-focused limited partnerships that each qualify as a VIE. Management determined the Company is not the primary beneficiary in any of these investments but does have the ability to exert significant influence over the operations and financial policies of the real estate joint venture and considers its investments in the limited partnerships to be more than minor. The Company’s investment in the real estate joint venture was $ 42.0 million and $ 42.3 million as of December 31, 2023 and 2022, respectively. The Company accounts for its investments in the technology-focused limited partnerships on a three month lag due to the timing the limited partnerships’ financial information is made available to the Company. As of December 31, 2023 and 2022, the Company’s investments in the limited partnerships were $ 46.5 million and $ 36.7 million , respectively, and are included in “Other assets” in the accompanying Consolidated Balance Sheets, with any related earnings, including unrealized gains and losses on the underlying investments of the limited partnerships which are recorded at estimated fair value, recognized in “Other non-operating (income) expense” in the accompanying Consolidated Statements of Operations. During the years ended December 31, 2023, 2022 and 2021 , the Company recognized $ 1.6 million of income, $ 35.4 million of expense and $ 51.7 million of income, respectively, from its investments in the limited partnerships. As of December 31, 2023, the Company was committed to make additional capital contributions totaling $ 33.6 million if and when called by the general partners of the limited partnerships. Other Assets Other assets consist primarily of receivables, the value of derivative contracts, right-of-use lease assets, investments in technology-focused limited partnerships, marketable equity securities, deferred rental concessions, the unamortized value of in-place leases and resident relationships, deferred financing costs relating to the revolving credit facility and commercial paper program and other prepaid expenses. Marketable Equity Securities Two of the technology-focused limited partnerships that are accounted for as investments in unconsolidated affiliates distributed publicly traded marketable equity securities to the Company and the other limited partners. During the years ended December 31, 2023 and 2022 , the Company received marketable equity securities totaling $ 7.7 million and $ 18.0 million, respectively, which are noncash investing activities. The Company’s investment in marketable equity securities is measured at fair value based on the quoted share price of the securities and is included in “Other assets” in the accompanying Consolidated Balance Sheets, with any related gains and losses, including unrealized gains and losses, recognized in “Other non-operating (income) expense” in the accompanying Consolidated Statements of Operations. As of December 31, 2023 and 2022 , the Company’s investment in the marketable equity securities was $ 18.6 million and $ 8.0 million, respectively. During the years ended December 31, 2023 and 2022 , the Company recognized $ 2.9 million of income and $ 10.0 million of expense, respectively, from its investment in marketable equity securities. Accrued Expenses and Other Liabilities Accrued expenses and other liabilities consist of accrued dividends payable, accrued real estate taxes, unearned income, right-of-use lease liabilities, security deposits, accrued payroll, general liability and workers compensation insurance, accrued capital improvements in progress, accrued interest payable, net deferred tax liability (see Note 7), accrued loss contingencies (see Note 11), accounts payable and other accrued expenses. The following table reflects a detail of the Company’s “Accrued expenses and other liabilities” balances as of December 31, 2023 and 2022 (dollars in thousands): December 31, 2023 December 31, 2022 Accrued dividends payable $ 176,162 $ 166,103 Accrued real estate taxes 159,041 135,510 Unearned income 65,180 65,129 Right-of-use lease liabilities 27,344 28,671 Security deposits 27,138 26,533 Accrued payroll 26,145 27,667 General liability and workers compensation insurance 24,399 22,624 Accrued capital improvements in progress 23,345 16,484 Accrued interest payable 21,941 25,132 Accounts payable, accrued expenses and other 94,461 101,990 Total $ 645,156 $ 615,843 Loss Contingencies The outcomes of claims, disputes and legal proceedings are subject to significant uncertainty. The Company records an accrual for loss contingencies when a loss is probable and the amount of the loss can be reasonably estimated. The Company also accrues an estimate of defense costs expected to be incurred in connection with legal matters. Management reviews these accruals quarterly and makes revisions based on changes in facts and circumstances. When a loss contingency is not both probable and reasonably estimable, management does 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 management discloses a reasonable estimate of the possible loss, or range of loss, if such reasonable estimate can be made. If the Company 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 considered 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, management’s experience in similar matters, the facts available to management at the time of assessment, and how the Company intends to respond, or has responded, to the proceeding or claim. Management’s assessment of these factors may change over time as individual proceedings or claims progress. For matters where management is 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 ultimately expected to be resolved through negotiation and settlement have not reached the point where management believes a reasonable estimate of loss, or range of loss, can be made. The Company believes that there is considerable uncertainty regarding the timing or ultimate resolution of such matters, including a possible eventual loss or business impact, if any. See Note 11 for additional disclosures regarding loss contingencies. Equity Forward Sale Agreements In August 2021, MAA entered into, and in the future may enter into, forward sale agreements for the sale and issuance of shares of its common stock, either through an underwritten public offering or through MAA’s at-the-market share offering program, or ATM program. When MAA enters into a forward sale agreement, the contract requires MAA to sell its shares to a counterparty at a predetermined price at a future date, which price is subject to adjustment during the term of the contract for MAA’s anticipated dividends as well as for a daily interest factor that varies with changes in the federal funds rate. MAA generally has the ability to determine the dates and method of settlement (i.e., gross physical settlement, net share settlement or cash settlement), subject to certain conditions and the right of the counterparty to accelerate settlement under certain circumstances. The Company accounts for the shares of MAA’s common stock reserved for issuance upon settlement as equity in accordance with ASC Topic 815-40, Contracts in Entity’s Own Equity , which permits equity classification when a contract is considered indexed to its own stock and the contract requires or permits the issuing entity to settle the contract in shares (either physically or net in shares). The guidance in ASC Topic 815-40 establishes a two-step process for evaluating whether an equity-linked financial instrument is considered indexed to its own stock by evaluating the instrument’s contingent exercise provisions and the instrument’s settlement provisions. In evaluating the forward sale agreements MAA has entered into, management concluded that (i) none of the agreements’ exercise contingencies are based on observable markets or indices besides those related to the market of MAA’s common stock price; and (ii) none of the settlement provisions preclude the agreements from being indexed to MAA’s common stock. Before the issuance of shares of MAA’s common stock upon physical or net share settlement of the forward sale agreements, the shares issuable upon settlement of the forward sale agreements are reflected in MAA’s diluted earnings per share calculations using the treasury stock method. Under this method, the number of shares of common stock used in calculating diluted earnings per share is deemed to be increased by the excess, if any, of the number of shares of common stock that would be issued upon full physical settlement of the forward sale agreements over the number of shares of common stock that could be purchased by MAA in the open market (based on the average market price during the period) using the proceeds to be received upon full physical settlement (based on the adjusted forward sale price at the end of the reporting period). When MAA physically or net share settles a forward sale agreement, the delivery of shares of common stock would result in an increase in the number of weighted average common shares outstanding and dilution to basic earnings per share. See Note 8 for additional disclosures regarding equity forward sale agreements. Revenue Recognition The Company primarily leases multifamily residential apartments to residents under operating leases generally due on a monthly basis with terms of approximately one year or less. Rental revenues are recognized in accordance with ASC Topic 842, Leases , using a method that represents a straight-line basis over the term of the lease. In addition, in circumstances where a lease incentive is provided to residents, the incentive is recognized as a reduction of rental revenues on a straight-line basis over the reasonably assured lease term. Rental revenues represent approximately 94 % of the Company’s total revenues and include gross rents charged less adjustments for concessions and bad debt. Approximately 5 % of the Company’s total revenues represent non-lease reimbursable property revenues from its residents for utility reimbursements, which are generally recognized and due on a monthly basis as residents obtain control of the service over the term of the lease. The remaining 1 % of the Company’s total revenues represents other non-lease property revenues primarily driven by nonrefundable fees and commissions, which are recognized when earned. In accordance with ASC Topic 842, rental revenues and non-lease reimbursable property revenues meet the criteria to be aggregated into a single lease component and are reported on a combined basis in the line item “Rental revenues,” as presented in the disaggregation of the Company’s revenues in Note 13. Other non-lease property revenues are accounted for in accordance with ASC Topic 606, Revenue from Contracts with Customers , which requires revenue recognized outside of the scope of ASC Topic 842 to be recognized when a customer obtains control of promised goods or services in an amount that reflects the consideration the entity expects to receive in exchange for those goods or services. Other non-lease property revenues are reported in the line item “Other property revenues,” as presented in the disaggregation of the Company’s revenues in Note 13. Advertising Costs Costs associated with advertising activities are expensed as incurred and were $ 26.6 million , $ 24.4 million and $ 23.9 million for the years ended December 31, 2023, 2022 and 2021 , respectively. Leases The Company is the lessee under certain ground, office, equipment and other operational leases, all of which are accounted for as operating leases in accordance with ASC Topic 842. The Company recognizes a right-of-use asset for the right to use the underlying asset for all leases where the Company is the lessee with terms of more than twelve months, and a related lease liability for the obligation to make lease payments. Expenses related to leases determined to be operating leases are recognized on a straight-line basis. As of December 31, 2023 and 2022 , r ight-of-use assets recorded within “Other assets” totaled $ 42.5 million and $ 44.6 million , respectively, and related lease liabilities recorded within “Accrued expenses and other liabilities” totaled $ 27.3 million and $ 28.7 million , respectively, in the Consolidated Balance Sheets. Lease expense recognized for the years ended December 31, 2023, 2022 and 2021 was immaterial to the Company. Cash paid for amounts included in the measurement of operating lease liabilities during the years ended December 31, 2023 and 2022 wa

Earnings Per Common Share Of M A A [Abstract]
Earnings per Common Share of MAA	2. Earnings per Common Share of MAA Basic earnings per share is computed using the two-class method by dividing net income available to MAA common shareholders by the weighted average number of common 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 diluted earnings per share being the more dilutive of the treasury stock or two-class methods. OP Units are included in dilutive earnings per share calculations when the units are dilutive to earnings per share. For the years ended December 31, 2023, 2022 and 2021, MAA’s diluted earnings per share was computed using the treasury stock method as presented below (dollars and shares in thousands, except per share amounts): Calculation of Earnings per common share - basic 2023 2022 2021 Net income $ 567,831 $ 654,776 $ 550,702 Net income attributable to noncontrolling interests ( 15,025 ) ( 17,340 ) ( 16,911 ) Unvested restricted shares (allocation of earnings) ( 224 ) ( 438 ) ( 539 ) Dividends to MAA Series I preferred shareholders ( 3,688 ) ( 3,688 ) ( 3,688 ) Net income available for MAA common shareholders, adjusted $ 548,894 $ 633,310 $ 529,564 Weighted average common shares - basic 116,521 115,344 114,717 Earnings per common share - basic $ 4.71 $ 5.49 $ 4.62 Calculation of Earnings per common share - diluted Net income $ 567,831 $ 654,776 $ 550,702 Net income attributable to noncontrolling interests (1) ( 15,025 ) ( 17,340 ) ( 16,911 ) Dividends to MAA Series I preferred shareholders ( 3,688 ) ( 3,688 ) ( 3,688 ) Net income available for MAA common shareholders, adjusted $ 549,118 $ 633,748 $ 530,103 Weighted average common shares - basic 116,521 115,344 114,717 Effect of dilutive securities 124 239 322 Weighted average common shares - diluted 116,645 115,583 115,039 Earnings per common share - diluted $ 4.71 $ 5.48 $ 4.61 (1) For the years ended December 31, 2023, 2022 and 2021 , 3.1 million, 3.2 million and 3.7 million OP Units and their related income are not included in the diluted earnings per share calculations as they are not dilutive.

Earnings per OP Unit of MAALP	3. Earnings per OP Unit of MAALP Basic earnings per common unit is computed using the two-class method by dividing net income available for common unitholders by the weighted average number of OP 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 common unit. Diluted earnings per common unit reflects the potential dilution that could occur if securities or other contracts to issue OP Units were exercised or converted into OP Units. Both the unvested restricted unit awards and other potentially dilutive common units, and the related impact to earnings, are considered when calculating earnings per common unit on a diluted basis with diluted earnings per common unit being the more dilutive of the treasury stock or two-class methods. For the years ended December 31, 2023, 2022 and 2021, MAALP’s diluted earnings per common unit was computed using the treasury stock method as presented below (dollars and units in thousands, except per unit amounts): Calculation of Earnings per common unit - basic 2023 2022 2021 Net income $ 567,831 $ 654,776 $ 550,702 Net (income) loss attributable to noncontrolling interests ( 62 ) 293 — Unvested restricted units (allocation of earnings) ( 224 ) ( 438 ) ( 539 ) Distributions to MAALP Series I preferred unitholders ( 3,688 ) ( 3,688 ) ( 3,688 ) Net income available for MAALP common unitholders, adjusted $ 563,857 $ 650,943 $ 546,475 Weighted average common units - basic 119,674 118,538 118,400 Earnings per common unit - basic $ 4.71 $ 5.49 $ 4.62 Calculation of Earnings per common unit - diluted Net income $ 567,831 $ 654,776 $ 550,702 Net (income) loss attributable to noncontrolling interests ( 62 ) 293 — Distributions to MAALP Series I preferred unitholders ( 3,688 ) ( 3,688 ) ( 3,688 ) Net income available for MAALP common unitholders, adjusted $ 564,081 $ 651,381 $ 547,014 Weighted average common units - basic 119,674 118,538 118,400 Effect of dilutive securities 124 239 322 Weighted average common units - diluted 119,798 118,777 118,722 Earnings per common unit - diluted $ 4.71 $ 5.48 $ 4.61

Stock Based Compensation [Abstract]
Stock-Based Compensation	4. 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 a number of incentives provided to attract and retain independent directors, executive officers and key employees. Incentives are currently granted under the 2023 Omnibus Incentive Plan, or the Omnibus Plan, which was approved at the 2023 annual meeting of MAA shareholders. The Omnibus Plan allows for the grant of awards, including restricted stock and stock options, with respect to up to 1,000,000 shares. Prior to the Omnibus Plan, incentives were awarded under the Amended and Restated 2013 Stock Incentive Plan, or the Stock Incentive Plan, which was approved at the 2018 annual meeting of MAA shareholders. The Stock Incentive Plan allowed for the grant of awards, including restricted stock and stock options, with respect to up to 2,000,000 shares. MAA believes that such awards better align the interests of its employees with those of its shareholders. The Omnibus Plan and the Stock Incentive Plan are collectively referred to as the Stock Plans. 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, compensation expense is adjusted for actual forfeitures for all awards in the period that the award was forfeited. 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 in “General and administrative expenses.” Total compensation expense under the Stock Plans was $ 18.3 million, $ 20.1 million and $ 18.2 million for the years ended December 31, 2023, 2022 and 2021 , respectively. Of these amounts, total compensation expense capitalized was $ 2.5 million, $ 1.3 million and $ 1.5 million for the years ended December 31, 2023, 2022 and 2021, respectively. As of December 31, 2023 , the total unrecognized compensation expense was $ 13.1 million. This cost is expected to be recognized over the remaining weighted average period of 0.8 years. Total cash paid for the settlement of plan shares totaled $ 7.9 million, $ 14.0 million and $ 9.0 million for the years ended December 31, 2023, 2022 and 2021, respectively. Information concerning grants under the Stock Plans is provided below. Restricted Stock In general, restricted stock is earned based on either a service condition, market condition, performance condition or a combination thereof and generally vests ratably over a period from the grant date up to 3 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 funds available for distribution 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, 2023, 2022 and 2021 , was $ 102.55 , $ 144.77 and $ 88.22 , 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, 2023, 2022 and 2021: 2023 2022 2021 Risk free rate 4.096 % 1.010 % 0.161 % Dividend yield 3.550 % 2.024 % 3.341 % Volatility 28.99 % 25.84 % 28.04 % Requisite service period 3 years 3 years 3 years The risk free rate was based on a zero coupon risk-free rate. 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 requisite service period is based on the criteria for the separate restricted stock awards according to the related vesting schedule. A summary of the status of the nonvested restricted shares as of December 31, 2023, and the changes for the year ended December 31, 2023, is presented below: Nonvested Shares Shares Weighted Average Grant-Date Fair Value Nonvested as of January 1, 2023 125,765 $ 136.60 Issued 131,090 128.71 Vested ( 159,590 ) 108.41 Forfeited ( 835 ) 176.55 Nonvested as of December 31, 2023 96,430 $ 172.18 The total fair value of shares vested during the years ended December 31, 2023, 2022 and 2021 was $ 17.3 million, $ 16.0 million and $ 15.8 million, respectively. Stock Options Options to purchase 463 shares of MAA's common stock were outstanding as of December 31, 2023 . No stock options were granted or expired during the years ended December 31, 2023, 2022 and 2021 . There were no options, 350 options and 19,032 options exercised during the years ended December 31, 2023, 2022 and 2021, respectively. These exercises resulted in net proceeds that were negligible during the year ended December 31, 2022 and $ 1.5 million for the year ended December 31, 2021 .

Fair Value Disclosures [Abstract]
Financial Instruments and Derivatives	6. Financial Instruments and Derivatives Financial Instruments Not Carried at Fair Value Cash and cash equivalents, restricted cash and accrued expenses and other liabilities are carried at amounts that reasonably approximate their fair value due to their short term nature. Fixed rate notes payable as of December 31, 2023 and 2022 totaled $ 4.0 billion and $ 4.4 billion, respectively, and had estimated fair values of $ 3.7 billion and $ 3.9 billion (excluding prepayment penalties) as of December 31, 2023 and 2022, respectively. The fair values of fixed rate debt are determined by using the present value of future cash outflows discounted with the applicable current market rate plus a credit spread. The carrying values of variable rate debt as of December 31, 2023 and 2022 totaled $ 495.0 million and $ 20.0 million , respectively, and the variable rate debt had estimated fair values of $ 495.0 million and $ 20.0 million as of December 31, 2023 and 2022 , respectively. The fair values of variable rate debt is determined using the stated variable rate plus the current market credit spread. The variable rates reset at various maturities typically less than 30 days , and management concluded these rates reasonably estimate current market rates. Financial Instruments Measured at Fair Value on a Recurring Basis As of December 31, 2023 , the Company had one outstanding series of cumulative redeemable preferred stock, which is referred to as the MAA Series I preferred stock (see Note 8). The Company has recognized a derivative asset related to the redemption feature embedded in the MAA Series I preferred stock. The derivative asset is valued using widely accepted valuation techniques, including a discounted cash flow analysis in which the perpetual value of the preferred shares is compared to the value of the preferred shares assuming the call option is exercised, with the value of the bifurcated call option as the difference between the two values. The analysis reflects the contractual terms of the redeemable preferred shares, which are redeemable at the Company’s option beginning on October 1, 2026 at the redemption price of $ 50.00 per share. The Company uses various inputs in the analysis, including trading data available on the preferred shares, estimated coupon yields on preferred stock instruments from REITs with similar credit ratings as MAA and treasury rates to estimate the fair value of the bifurcated call option. The redemption feature embedded in the MAA Series I preferred stock is reported as a derivative asset in “Other assets” in the accompanying Consolidated Balance Sheets and is adjusted to its fair value at each reporting date, with a corresponding non-cash adjustment to “Other non-operating (income) expense” in the accompanying Consolidated Statements of Operations. As of December 31, 2023 and 2022, the fair value of the embedded derivative was $ 31.9 million and $ 13.4 million , respectively. The Company has determined the majority of the inputs used to value its outstanding debt and its embedded derivative fall within Level 2 of the fair value hierarchy, and as a result, the fair value valuations of its debt and embedded derivative held as of December 31, 2023 and 2022 were classified as Level 2 in the fair value hierarchy. The fair value of the Company’s marketable equity securities discussed in Note 1 is based on quoted market prices and are classified as Level 1 in the fair value hierarchy. Terminated Cash Flow Hedges of Interest As of December 31, 2023, the Company had $ 8.8 million recorded in “Accumulated other comprehensive loss,” or AOCL, related to realized losses associated with terminated interest rate swaps that were designated as cash flow hedging instruments prior to their termination. The realized losses associated with the terminated interest rate swaps are reclassified to interest expense as interest payments are made on the Company’s debt and will continue to be reclassified to interest expense until the debt’s maturity. During the next 12 months, the Company estimates an additional $ 1.9 million will be reclassified to earnings as an increase to “Interest expense.” Tabular Disclosure of the Effect of Derivative Instruments on the Consolidated Statements of Operations The tables below present the effect of the Company’s derivative financial instruments on the Consolidated Statements of Operations for the years ended December 31, 2023, 2022 and 2021, respectively (dollars in thousands): Derivatives in Cash Flow Location of Loss Reclassified Net Loss Reclassified from AOCL into Interest Expense Hedging Relationships from AOCL into Income 2023 2022 2021 Terminated interest rate swaps Interest expense $ ( 1,326 ) $ ( 1,114 ) $ ( 1,114 ) Derivatives Not Designated Location of Gain (Loss) Recognized Gain (Loss) Recognized in Earnings on Derivative as Hedging Instruments in Earnings on Derivative 2023 2022 2021 Preferred stock embedded derivative Other non-operating (income) expense $ 18,528 $ ( 21,107 ) $ ( 4,560 )

Income Taxes

Income Taxes [Abstract]
Income Taxes	7. Income Taxes Due to the structure of MAA as a REIT and the nature of the operations of its operating properties, no provision for federal income taxes has been made at the MAA level. In addition, as MAALP is structured as a limited partnership, and its partners recognize their proportionate share of income or loss in their tax returns, no provision for federal income taxes has been made at the MAALP level. Historically, the Company has incurred certain state and local income, excise and franchise taxes. Taxable REIT Subsidiaries A TRS is an entity that is subject to federal , state and any applicable local corporate income tax without the benefit of the dividends paid deduction applicable to REITs. The Company’s TRS generated taxable income of $ 4.6 million for the year ended December 31, 2023 , taxable loss of $ 45.2 million for the year ended December 31, 2022 and taxable income of $ 51.8 million for the year ended December 31, 2021 . The Company’s TRS recognized income tax expense of $ 1.0 million for the year ended December 31, 2023 , income tax benefit of $ 9.5 million for the year ended December 31, 2022 and income tax expense of $ 10.9 million for the year ended December 31, 2021. One of the Company’s TRS generally provides the Company with services (property management services to a real estate joint venture and other services) for which the Company reimburses the TRS. In addition, one of the Company’s TRS owns the investments in the technology-focused limited partnerships and marketable securities that generate investment income and losses. The investment income or loss is recognized for tax purposes at the time of sale or exchange of the investment. In addition to the TRS income tax provision, income tax expense primarily relates to the Texas-based margin tax for all Texas apartment communities. Income tax expense for the Company for the year ended December 31, 2023 was $ 4.7 million, income tax benefit for the year ended December 31, 2022 was $ 6.2 million and income tax expense for the year ended December 31, 2021 was $ 13.6 million, as presented in “Income tax (expense) benefit” in the accompanying Consolidated Statements of Operations. As of December 31, 2023 and 2022, the components of the Company’s TRS deferred income tax assets and liabilities were as follows (dollars in thousands): December 31, 2023 December 31, 2022 Deferred tax liability: Unrealized gain from limited partnerships $ 300 $ 1,122 Unrealized gain from marketable securities & other 3,575 1,700 Total deferred tax liability $ 3,875 $ 2,822 Net deferred tax liability $ 3,875 $ 2,822 The net deferred tax liability balances are reflected in “Accrued expenses and other liabilities” in the accompanying Consolidated Balance Sheets. The TRS have no reserve for uncertain tax positions for the years ended December 31, 2023 and 2022, and management does not believe there will be any material changes in the TRS unrecognized tax positions over the next 12 months. If necessary, the TRS accrue interest and penalties on unrecognized tax benefits as a component of income tax expense. Net Operating Loss Carryforwards As of December 31, 2023 , the Company held federal net operating loss, or NOL, carryforwards of $ 46.2 million for income tax purposes that expire in the years 2024 to 2032. Utilization of any 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 prior to utilization. The Company may use these NOL to offset all or a portion of the taxable income generated at the REIT level. Tax years 2020 through 2023 are subject to examination by the Internal Revenue Service. No tax examination is currently in process. Taxable Composition of Distributions For income tax purposes, dividends paid to holders of common stock generally 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, 2023, 2022 and 2021, dividends per share held for the entire year were estimated to be taxable as follows: 2023 2022 2021 Amount Percentage Amount Percentage Amount Percentage Ordinary income $ 5.60 100.00 % $ 4.44 95.03 % $ 2.43 59.18 % Capital gains — — 0.23 4.78 % 1.36 33.15 % Un-recaptured Section 1250 gains — — 0.01 0.19 % 0.31 7.67 % Total $ 5.60 100 % $ 4.68 100 % $ 4.10 100 % The Company 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 taxable gains on sold properties.

Shareholders Equity Of M A A [Abstract]
Shareholders' Equity of MAA	8. Shareholders’ Equity of MAA As of December 31, 2023, 116,694,124 shares of common stock of MAA and 3,143,972 OP Units (excluding the OP Units held by MAA) were issued and outstanding, representing a total of 119,838,096 common shares and units. As of December 31, 2022, 115,480,336 shares of common stock of MAA and 3,164,933 OP Units (excluding the OP Units held by MAA) were issued and outstanding, representing a total of 118,645,269 common shares and units. Preferred Stock As of December 31, 2023, MAA had one outstanding series of cumulative redeemable preferred stock, which has the following characteristics: Description Outstanding Shares Liquidation Preference (1) Optional Redemption Date Redemption Price (2) Stated Dividend Yield Approximate Dividend Rate MAA Series I 867,846 $ 50.00 10/1/2026 $ 50.00 8.50 % $ 4.25 (1) The total liquidation preference for the outstanding preferred stock is $ 43.4 million . (2) The redemption price is the price at which the preferred stock is redeemable, at MAA’s option, for cash. See Note 6 for details of the valuation of the derivative asset related to the redemption feature embedded in the MAA Series I preferred stock. 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 common shareholders have the ability to reinvest all or part of their distributions from MAA into shares of MAA’s common stock and holders of Class A OP Units have the ability to reinvest all or part of their distributions from the Operating Partnership 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. 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 currently has registered with the SEC the offer and sale of up to 1,906,762 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 MAA’s common stock totaling 9,787 in 2023, 6,547 in 2022 and 6,301 in 2021 were acquired by participants under the DRSPP. MAA did not offer a discount for optional cash purchases in 2023, 2022 or 2021. Equity Forward Sale Agreements In August 2021, MAA entered into two 18-month forward sale agreements with respect to a total of 1.1 million shares of its common stock at an initial forward sale price of $ 190.56 per share, which is net of issuance costs. Under the forward sale agreements, the forward sale price was subject to adjustment on a daily basis based on a floating interest rate factor equal to a specified daily rate less a spread and was decreased based on amounts related to dividends on MAA’s common stock during the term of the forward sale agreements. In January 2023, MAA settled its two forward sale agreements with respect to a total of 1.1 million shares at a forward price per share of $ 185.23 , which is inclusive of adjustments made to reflect the then-current federal funds rate, the amount of dividends paid to holders of MAA common stock and commissions paid to sales agents, for net proceeds of $ 203.7 million. The impact of the forward sale agreements was no t dilutive to the Company’s diluted earnings per share for the years ended December 31, 2023 and 2022. At-the-Market Share Offering Program In November 2021, the Company entered into an equity distribution agreement to establish a new ATM program, replacing MAA’ s previous ATM program and allowing MAA to sell shares of its common stock from time to time to or through its sales agents into the existing market at current market prices, and to enter into separate forward sales agreements to or through its forward purchasers. Under its current ATM program, MAA has the authority to issue up to an aggregate of 4.0 million shares of its common stock, at such times to be determined by MAA. MAA has no obligation to issue shares through the ATM program. During the years ended December 31, 2023, 2022 and 2021 MAA did no t sell any shares of common stock under its ATM program. As of December 31, 2023, 4.0 million shares remained issuable under the current ATM program.

Partners' Capital of MAALP

Partners' Capital of MAALP	12 Months Ended
	Dec. 31, 2023
Partners' Capital Notes [Abstract]
Partners' Capital of MAALP	9. Partners’ Capital of MAALP Common units of limited partnership interests in MAALP are represented by OP Units. As of December 31, 2023, there were 119,838,096 OP Units outstanding, 116,694,124 , or 97.4 % , of which represent Class B OP Units (common units issued to or held by MAALP’s general partner or any of its subsidiaries), which were owned by MAA, MAALP’s general partner. The remaining 3,143,972 OP Units were Class A OP Units owned by Class A limited partners. As of December 31, 2022, there were 118,645,269 OP Units outstanding, 115,480,336 , or 97.3 % , of which were owned by MAA and 3,164,933 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 MAALP subject to the restrictions specifically contained within MAALP’s agreement of limited partnership, or the Partnership Agreement. Unless otherwise stated in the Partnership Agreement, 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 MAALP’s assets; and distribution of MAALP’s 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 to it if the general partner remains in supervision of the designee. Under the Partnership Agreement, MAALP may issue Class A OP Units and Class B OP Units. Class A OP Units are any OP Units other than Class B OP Units, while Class B OP Units are those issued to or held by MAALP’s general partner or any of its subsidiaries. In general, the limited partners do not have the power to participate in the management or control of MAALP’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 OP Units is also limited by the Partnership Agreement. Net income of MAALP (after allocations to preferred ownership interests) is allocated to the general partner and limited partners based on their respective ownership percentages of MAALP. Issuance or redemption of additional Class A OP Units or Class B OP Units changes the relative ownership percentage of the partners. The issuance of Class B OP Units generally occurs when MAA issues common stock and the proceeds from that issuance are contributed to MAALP 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, MAALP generally redeems an equal number of Class B OP 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 MAALP. Holders of the Class A OP Units may require MAA to redeem their Class A OP Units, in which case MAA may, at its option, pay the redemption price either in cash (in an amount per Class A OP Unit equal, in general, to the average closing price of MAA’s common stock on the NYSE 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 OP Unit so redeemed. As of December 31, 2023, a total of 3,143,972 Class A OP Units were outstanding and redeemable for 3,143,972 shares of MAA common stock, with an approximate value of $ 422.7 million , based on the closing price of MAA’s common stock on December 31, 2023 of $ 134.46 per share. As of December 31, 2022, a total of 3,164,933 Class A OP Units were outstanding and redeemable for 3,164,933 shares of MAA common stock, with an approximate value of $ 496.9 million , based on the closing price of MAA’s common stock on December 31, 2022 of $ 156.99 per share. MAALP pays the same per unit distributions in respect to the OP Units as the per share dividends MAA pays in respect to its common stock. As of December 31, 2023, MAALP had one outstanding series of cumulative redeemable preferred units, or the MAALP Series I preferred units. The MAALP Series I preferred units have the same characteristics as the MAA Series I preferred stock described in Note 8. As of December 31, 2023, 867,846 units of the MAALP Series I preferred units were outstanding and owned by MAA. See Note 6 for details of the valuation of the derivative asset related to the redemption feature embedded in the MAALP Series I preferred units.

Employee Benefit Plans

Employee Benefit Plans [Abstract]
Employee Benefit Plans	10. Employee Benefit Plans The following provides details of the employee benefit plans not previously discussed in Note 4. 401(k) Savings Plans 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 to the 401(k) Plan. MAA recognized expense from the 401(k) Plan of $ 4.7 million , $ 4.4 million and $ 4.1 million for the years ended December 31, 2023, 2022 and 2021, respectively. Non-Qualified Executive Deferred Compensation Retirement Plan MAA has adopted the MAA Non-Qualified Executive Deferred Compensation Retirement Plan Amended and Restated effective January 1, 2016, or the Deferred Compensation Plan, for certain executive employees. Under the terms of the Deferred Compensation Plan, employees may elect to defer a percentage of their compensation and bonus, and MAA may, but is not obligated to, match a portion of the employees’ salary deferral. MAA recognized expense on its match to the Deferred Compensation Plan for the years ended December 31, 2023, 2022 and 2021 of $ 0.4 million , $ 0.5 million and $ 0.1 million , respectively. Non-Qualified Deferred Compensation Plan for Outside Company Directors MAA has adopted the Non-Qualified Deferred Compensation Plan for Outside Company Directors as Amended effective November 30, 2010, 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, 2023, 2022 and 2021, directors deferred 9,459 shares, 6,122 shares and 6,944 shares of common stock, respectively, with weighted-average grant date fair values of $ 145.96 , $ 174.76 and $ 164.23 , 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 the 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. As of December 31, 2023, there was no liability related to mandatorily redeemable shares. As of December 31, 2022 , $ 0.7 million of mandatorily redeemable shares were recorded as a liability and classified in “Accrued expenses and other liabilities” in the Consolidated Balance Sheets. 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. On December 31, 2010, the ESOP was frozen by amendment, whereby effective January 1, 2011, no additional employees became eligible for the plan, no additional contributions were made to the ESOP, and all participants with an account balance under the ESOP became 100% vested. The Company did not contribute to the ESOP during 2023, 2022 or 2021. As of December 31, 2023, the ESOP held 123,762 shares with a fair value of $ 16.6 million .

Loss Contingency [Abstract]
Commitments and Contingencies	11. Commitments and Contingencies Leases The Company’s operating leases include a ground lease expiring in 2074 related to one of its apartment communities and an office lease expiring in 2028 related to its corporate headquarters. Both leases contain stated rent increases that are generally intended to compensate for the impact of inflation. The Company also has other commitments related to negligible office and equipment operating leases. As of December 31, 2023, the Company’s operating leases had a weighted average remaining lease term of approximately 34 years and a weighted average discount rate of approximately 4.5 %. The table below reconciles undiscounted cash flows for each of the first five years and total of the remaining years to the right-of-use lease liabilities recorded on the Consolidated Balance Sheets as of December 31, 2023 (in thousands): Operating Leases 2024 $ 2,951 2025 2,919 2026 2,968 2027 3,002 2028 1,583 Thereafter 55,605 Total minimum lease payments 69,028 Net present value adjustments ( 41,684 ) Right-of-use lease liabilities $ 27,344 Legal Proceedings In late 2022 and early 2023, 28 putative class action lawsuits were filed against RealPage, Inc., along with over 50 of the largest owners and operators of apartment communities in the country, including the Company (the “RealPage Litigation”), alleging that RealPage and lessors of multifamily residential real estate conspired to artificially inflate the prices of multifamily residential real estate above competitive levels through the use of RealPage’s revenue management software. The plaintiffs are seeking monetary damages and attorneys’ fees and costs and injunctive relief. The Company believes the RealPage Litigation is without merit as it pertains to the Company and plans to vigorously defend the RealPage Litigation. On April 10, 2023, the Joint Panel on Multidistrict Litigation issued an order centralizing the cases in the Middle District of Tennessee for coordinated or consolidated pretrial proceedings. The Company is unable to predict the outcome of the RealPage Litigation given its early stage. While the Company does not believe that the RealPage Litigation will have a material adverse effect on its financial condition, the Company cannot give assurance that the RealPage Litigation will not have a material effect on its results of operations. The Company is subject to various other legal proceedings and claims that arise in the ordinary course of its business operations. While the resolution of these matters cannot be predicted with certainty, management does not currently believe that these matters, either individually or in the aggregate, will have a material adverse effect on the Company’s financial condition, results of operations or cash flows in the event of a negative outcome. Matters that arise out of allegations of bodily injury, property damage and employment practices are generally covered by insurance. As of December 31, 2023 and 2022, the Company’s accrual for loss contingencies relating to unresolved legal matters, including the cost to defend, was $ 7.6 million and $ 10.0 million in the aggregate, respectively. The loss contingencies are presented in “Accrued expenses and other liabilities” in the accompanying Consolidated Balance Sheets.

Related Party Transactions [Abstract]
Related Party Transactions	12. Related Party Transactions The 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 negligible payable to MAA, its general partner, as of December 31, 2023 and 2022 that is eliminated in the preparation of MAA’s consolidated financial statements. The Partnership Agreement does not require the due to/due from balance to be settled in cash until liquidation of the Operating Partnership, and therefore, there is no regular settlement schedule for such amounts.

Segment Information

Segment Information	12 Months Ended

Notes To Financial Statements [Abstract]
Segment Information	13. Segment Information As of December 31, 2023, the Company owned and operated 290 multifamily apartment communities (which does not include development communities under construction) in 15 different states from which it derived all significant sources of earnings and operating cash flows. The Company views each consolidated apartment community as an operating segment. The Company’s chief operating decision maker, which is the Company’s Chief Executive Officer, evaluates performance and determines resource allocations of each of the apartment communities on a Same Store and Non-Same Store and Other basis, as well as an individual apartment community basis. The Company has aggregated its operating segments into two reportable segments as management believes the apartment communities in each reportable segment generally have similar economic characteristics, facilities, services and residents. The following reflects the two reportable segments for the Company: • Same Store includes communities that the Company has owned and have been stabilized for at least a full 12 months as of the first day of the calendar year. • Non-Same Store and Other includes recently acquired communities, communities being developed or in lease-up, communities that have been disposed of or identified for disposition, communities that have experienced a significant casualty loss and stabilized communities that do not meet the requirements to be Same Store communities. Also included in Non-Same Store and Other are non-multifamily activities and storm related expenses related to hurricanes. On the first day of each calendar year, the Company determines the composition of its Same Store and Non-Same Store and Other reportable segments for that year as well as adjusts the previous year, which allows the Company to evaluate full period-over-period operating comparisons. Communities previously in development or lease-up are added to the Same Store segment on the first day of the calendar year after the community has been owned and stabilized for at least a full 12 month s. Communities are considered stabilized when achieving 90 % average physical occupancy for 90 days . The chief operating decision maker utilizes NOI in evaluating the performance of the operating 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. Management believes that NOI is a helpful tool in evaluating the operating performance of the segments because it measures the core operations of property performance by excluding corporate level expenses and other items not directly related to property operating performance. Revenues and NOI for each reportable segment for the years ended December 31, 2023, 2022 and 2021 were as follows (in thousands): 2023 2022 2021 Revenues: Same Store Rental revenues $ 2,013,283 $ 1,895,071 $ 1,683,380 Other property revenues 11,468 11,932 11,854 Total Same Store revenues 2,024,751 1,907,003 1,695,234 Non-Same Store and Other Rental revenues 122,935 111,067 81,822 Other property revenues 782 1,796 1,026 Total Non-Same Store and Other revenues 123,717 112,863 82,848 Total rental and other property revenues $ 2,148,468 $ 2,019,866 $ 1,778,082 Net Operating Income: Same Store NOI $ 1,306,939 $ 1,232,893 $ 1,061,572 Non-Same Store and Other NOI 73,388 63,279 45,345 Total NOI 1,380,327 1,296,172 1,106,917 Depreciation and amortization ( 565,063 ) ( 542,998 ) ( 533,433 ) Property management expenses ( 67,784 ) ( 65,463 ) ( 55,732 ) General and administrative expenses ( 58,578 ) ( 58,833 ) ( 52,884 ) Interest expense ( 149,234 ) ( 154,747 ) ( 156,881 ) (Loss) gain on sale of depreciable real estate assets ( 62 ) 214,762 220,428 Gain on sale of non-depreciable real estate assets 54 809 811 Other non-operating income (expense) 31,185 ( 42,713 ) 33,902 Income tax (expense) benefit ( 4,744 ) 6,208 ( 13,637 ) Income from real estate joint venture 1,730 1,579 1,211 Net income attributable to noncontrolling interests ( 15,025 ) ( 17,340 ) ( 16,911 ) Dividends to MAA Series I preferred shareholders ( 3,688 ) ( 3,688 ) ( 3,688 ) Net income available for MAA common shareholders $ 549,118 $ 633,748 $ 530,103 Assets for each reportable segment as of December 31, 2023 and 2022 were as follows (in thousands): December 31, 2023 December 31, 2022 Assets: Same Store $ 9,509,470 $ 9,697,889 Non-Same Store and Other 1,776,165 1,370,721 Corporate 198,868 172,555 Total assets $ 11,484,503 $ 11,241,165

Real Estate [Abstract]
Real Estate Acquisitions and Dispositions	14. Real Estate Acquisitions and Dispositions During the year ended December 31, 2023 , the Company closed on the acquisition of a 323 -unit multifamily apartment community located in the Phoenix, Arizona market for approximately $ 103 million and a 352 -unit multifamily apartment community located in the Charlotte, North Carolina market for approximately $ 107 million. During the year ended December 31, 2022, the Company acquired a 196 -unit multifamily apartment community located in the Tampa, Florida market for approximately $ 73 million and a 344 -unit multifamily apartment community located in the Charlotte, North Carolina market for approximately $ 140 million. During the year ended December 31, 2023, the Company did not dispose of any multifamily apartment communities. During the year ended December 31, 2022, the Company closed on the dispositions of two multifamily communities in the Fort Worth, Texas market, one multifamily community in Maryland and one multifamily community in the Austin, Texas market. The Company received combined gross proceeds of approximately $ 325 million and recognized a combined gain on the sale of depreciable real estate assets of approximately $ 215 million.

Organization and Summary of Significant Accounting Policies (Policies)	12 Months Ended

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 the Company’s management in accordance with U.S. 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, directly or indirectly, approximately 80 % to 100 % of all consolidated subsidiaries, including the Operating Partnership. In management’s 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. The Company invests in entities that may qualify as variable interest entities, or VIEs, and MAALP is considered a 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. MAALP is classified as a VIE because the limited partners lack substantive kick-out rights and substantive participating rights, and the Company is its primary beneficiary. The Company consolidates all VIEs for which it is the primary beneficiary and uses the equity method to account for investments that qualify as VIEs but for which it is not the primary beneficiary. In determining whether the Company is the primary beneficiary of a VIE, management considers both 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. The Company uses the equity method of accounting for its investments in entities for which the Company exercises significant influence but does not have the ability to exercise control. The factors considered in determining whether the Company has the ability to exercise significant influence or control include ownership of voting interests and participatory rights of investors (see “Investments in Unconsolidated Affiliates” below).
Noncontrolling Interests	Noncontrolling Interests As of December 31, 2023, the Company had two types of noncontrolling interests with respect to its consolidated subsidiaries: (1) noncontrolling interests related to the common unitholders of its Operating Partnership; and (2) noncontrolling interests related to its consolidated real estate entities. The noncontrolling interests relating to the limited partnership interests in the Operating Partnership are owned by the holders of the Class A OP Units. MAA is the sole general partner of the Operating Partnership and holds all of the outstanding Class B OP Units. Net income (after allocations to preferred ownership interests) is allocated to MAA and the noncontrolling interests based on their respective ownership percentages of the Operating Partnership. Issuance of additional Class A OP Units or Class B OP Units changes the ownership percentage of both the noncontrolling interests and MAA. The issuance of Class B OP Units generally occurs when MAA issues common stock and the issuance proceeds are contributed to the Operating Partnership in exchange for Class B OP Units equal to the number of shares of MAA’s common stock issued. At each reporting period, the allocation between total MAA shareholders’ equity and noncontrolling interests 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 OP Unit that were equivalent to the economic rights in respect to each share of MAA common stock. See Note 9 for additional details. The noncontrolling interests relating to the Company’s consolidated real estate entities are owned by private real estate companies that are generally responsible for the development, construction and lease-up of the apartment communities that are owned through the consolidated real estate entities with a noncontrolling interest. The entities were determined to be VIE’s with the Company designated as the primary beneficiary. As a result, the accounts of the entities are consolidated by the Company. As of December 31, 2023, the consolidated assets of the Company’s consolidated real estate entities with a noncontrolling interest were $ 265.1 million , and consolidated liabilities were $ 12.9 million . As of December 31, 2022, the consolidated assets of the Company’s consolidated real estate entities with a noncontrolling interest were $ 279.6 million , and consolidated liabilities were $ 14.5 million . During the years ended December 31, 2023 and 2022 , the Company paid $ 15.8 million and $ 43.1 million, respectively, to acquire the noncontrolling interest of a consolidated real estate entity.
Real Estate Assets and Depreciation and Amortization	Real Estate Assets and Depreciation and Amortization Real estate assets are carried at depreciated cost and consist of land, buildings and improvements and other, and development and capital improvements in progress (see “Development Costs” below). Repairs and maintenance costs are expensed as incurred, while significant improvements, renovations and recurring capital replacements are capitalized and depreciated over their estimated useful lives. 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, the Company also capitalizes 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 and blinds are typically expensed as incurred. Depreciation is computed on a straight-line basis over the estimated useful lives of the related assets, which range from three to 40 years. The line item “Buildings and improvements and other” in the Consolidated Balance Sheets includes land improvements and buildings, which have a useful life ranging from five to 40 years , as well as furniture, fixtures and equipment, which have a useful life of three to five years.
Development Costs	Development Costs Development projects and the related carrying costs, including interest, property taxes, insurance and allocated direct development salary costs 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 or floors within a development, amounts representing the completed portion of total estimated development costs for the project are transferred to “Buildings and improvements and other” 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 capitalized costs (including capitalized interest, property taxes, insurance and salaries) during the years ended December 31, 2023, 2022 and 2021 were $ 20.6 million , $ 14.4 million and $ 16.6 million , respectively. Certain costs associated with the lease-up of development projects, including cost of model units, furnishings and signs, 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 Codification, or ASC, Topic 805, Business Combinations , most acquisitions of operating properties qualify as an asset acquisition. Accordingly, the cost of the real estate acquired, including acquisition costs, is allocated to the acquired tangible assets, consisting of land, buildings and improvements and other, and identified intangible assets, consisting of the value of in-place leases and other contracts, on a relative fair value basis. Acquisition costs include appraisal fees, title fees, broker fees and other legal costs to acquire the property. The purchase price of an acquired property is allocated based on the relative fair value of the individual components as a proportion of the total assets acquired. The Company allocates the cost of the tangible assets of an acquired property 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. The Company allocates the cost of land based on its relative fair value if acquired with a multifamily community or records the value based on the purchase price paid if acquired separately. In allocating the cost 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 approximate at-market rates since the residential lease terms generally do not extend beyond one year. For residential leases, the fair value of the in-place leases and resident relationships is amortized over the remaining term of the resident leases. For retail and commercial leases, the fair value of in-place leases and tenant relationships is amortized over the remaining term of the leases. The net amount of these lease intangibles included in “Other assets” totaled $ 1.6 million and $ 0.8 million as of December 31, 2023 and 2022 , respectively.
Impairment of Long-lived Assets	Impairment of Long-lived Assets The Company accounts for long-lived assets in accordance with the provisions of accounting standards for the impairment or disposal of long-lived assets. Management periodically evaluates long-lived assets, including investments in real estate, 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 future undiscounted 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 in the appropriate asset and liability sections in the Consolidated Balance Sheets, are reported at the lower of the carrying amount or fair value less costs to sell and are no longer depreciated.
Undeveloped Land	Undeveloped Land Undeveloped land includes sites intended for future multifamily developments and sites for future commercial development, which are carried at cost and evaluated for impairment when indicators are present. Any costs incurred prior to commencement of pre-development activities are expensed as incurred.
Cash and Cash Equivalents	Cash and Cash Equivalents Investments in money market accounts and certificates of deposit with original maturities of three months or less are considered 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 cash held for exchanges under Section 1031(b) of the Internal Revenue Code of 1986, as amended, or the Code. Section 1031(b) exchanges are presented within “Cash, cash equivalents and restricted cash” in the accompanying Consolidated Statements of Cash Flows.
Investments in Unconsolidated Affiliates	Investments in Unconsolidated Affiliates The Company uses the equity method to account for its investments in a real estate joint venture and six technology-focused limited partnerships that each qualify as a VIE. Management determined the Company is not the primary beneficiary in any of these investments but does have the ability to exert significant influence over the operations and financial policies of the real estate joint venture and considers its investments in the limited partnerships to be more than minor. The Company’s investment in the real estate joint venture was $ 42.0 million and $ 42.3 million as of December 31, 2023 and 2022, respectively. The Company accounts for its investments in the technology-focused limited partnerships on a three month lag due to the timing the limited partnerships’ financial information is made available to the Company. As of December 31, 2023 and 2022, the Company’s investments in the limited partnerships were $ 46.5 million and $ 36.7 million , respectively, and are included in “Other assets” in the accompanying Consolidated Balance Sheets, with any related earnings, including unrealized gains and losses on the underlying investments of the limited partnerships which are recorded at estimated fair value, recognized in “Other non-operating (income) expense” in the accompanying Consolidated Statements of Operations. During the years ended December 31, 2023, 2022 and 2021 , the Company recognized $ 1.6 million of income, $ 35.4 million of expense and $ 51.7 million of income, respectively, from its investments in the limited partnerships. As of December 31, 2023, the Company was committed to make additional capital contributions totaling $ 33.6 million if and when called by the general partners of the limited partnerships.
Other Assets	Other Assets Other assets consist primarily of receivables, the value of derivative contracts, right-of-use lease assets, investments in technology-focused limited partnerships, marketable equity securities, deferred rental concessions, the unamortized value of in-place leases and resident relationships, deferred financing costs relating to the revolving credit facility and commercial paper program and other prepaid expenses.
Marketable Equity Securities	Marketable Equity Securities Two of the technology-focused limited partnerships that are accounted for as investments in unconsolidated affiliates distributed publicly traded marketable equity securities to the Company and the other limited partners. During the years ended December 31, 2023 and 2022 , the Company received marketable equity securities totaling $ 7.7 million and $ 18.0 million, respectively, which are noncash investing activities. The Company’s investment in marketable equity securities is measured at fair value based on the quoted share price of the securities and is included in “Other assets” in the accompanying Consolidated Balance Sheets, with any related gains and losses, including unrealized gains and losses, recognized in “Other non-operating (income) expense” in the accompanying Consolidated Statements of Operations. As of December 31, 2023 and 2022 , the Company’s investment in the marketable equity securities was $ 18.6 million and $ 8.0 million, respectively. During the years ended December 31, 2023 and 2022 , the Company recognized $ 2.9 million of income and $ 10.0 million of expense, respectively, from its investment in marketable equity securities.
Accrued Expenses and Other Liabilities	Accrued Expenses and Other Liabilities Accrued expenses and other liabilities consist of accrued dividends payable, accrued real estate taxes, unearned income, right-of-use lease liabilities, security deposits, accrued payroll, general liability and workers compensation insurance, accrued capital improvements in progress, accrued interest payable, net deferred tax liability (see Note 7), accrued loss contingencies (see Note 11), accounts payable and other accrued expenses. The following table reflects a detail of the Company’s “Accrued expenses and other liabilities” balances as of December 31, 2023 and 2022 (dollars in thousands): December 31, 2023 December 31, 2022 Accrued dividends payable $ 176,162 $ 166,103 Accrued real estate taxes 159,041 135,510 Unearned income 65,180 65,129 Right-of-use lease liabilities 27,344 28,671 Security deposits 27,138 26,533 Accrued payroll 26,145 27,667 General liability and workers compensation insurance 24,399 22,624 Accrued capital improvements in progress 23,345 16,484 Accrued interest payable 21,941 25,132 Accounts payable, accrued expenses and other 94,461 101,990 Total $ 645,156 $ 615,843 Loss Contingencies The outcomes of claims, disputes and legal proceedings are subject to significant uncertainty. The Company records an accrual for loss contingencies when a loss is probable and the amount of the loss can be reasonably estimated. The Company also accrues an estimate of defense costs expected to be incurred in connection with legal matters. Management reviews these accruals quarterly and makes revisions based on changes in facts and circumstances. When a loss contingency is not both probable and reasonably estimable, management does 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 management discloses a reasonable estimate of the possible loss, or range of loss, if such reasonable estimate can be made. If the Company 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 considered 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, management’s experience in similar matters, the facts available to management at the time of assessment, and how the Company intends to respond, or has responded, to the proceeding or claim. Management’s assessment of these factors may change over time as individual proceedings or claims progress. For matters where management is 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 ultimately expected to be resolved through negotiation and settlement have not reached the point where management believes a reasonable estimate of loss, or range of loss, can be made. The Company believes that there is considerable uncertainty regarding the timing or ultimate resolution of such matters, including a possible eventual loss or business impact, if any. See Note 11 for additional disclosures regarding loss contingencies.
Equity Forward Sale Agreements	Equity Forward Sale Agreements In August 2021, MAA entered into, and in the future may enter into, forward sale agreements for the sale and issuance of shares of its common stock, either through an underwritten public offering or through MAA’s at-the-market share offering program, or ATM program. When MAA enters into a forward sale agreement, the contract requires MAA to sell its shares to a counterparty at a predetermined price at a future date, which price is subject to adjustment during the term of the contract for MAA’s anticipated dividends as well as for a daily interest factor that varies with changes in the federal funds rate. MAA generally has the ability to determine the dates and method of settlement (i.e., gross physical settlement, net share settlement or cash settlement), subject to certain conditions and the right of the counterparty to accelerate settlement under certain circumstances. The Company accounts for the shares of MAA’s common stock reserved for issuance upon settlement as equity in accordance with ASC Topic 815-40, Contracts in Entity’s Own Equity , which permits equity classification when a contract is considered indexed to its own stock and the contract requires or permits the issuing entity to settle the contract in shares (either physically or net in shares). The guidance in ASC Topic 815-40 establishes a two-step process for evaluating whether an equity-linked financial instrument is considered indexed to its own stock by evaluating the instrument’s contingent exercise provisions and the instrument’s settlement provisions. In evaluating the forward sale agreements MAA has entered into, management concluded that (i) none of the agreements’ exercise contingencies are based on observable markets or indices besides those related to the market of MAA’s common stock price; and (ii) none of the settlement provisions preclude the agreements from being indexed to MAA’s common stock. Before the issuance of shares of MAA’s common stock upon physical or net share settlement of the forward sale agreements, the shares issuable upon settlement of the forward sale agreements are reflected in MAA’s diluted earnings per share calculations using the treasury stock method. Under this method, the number of shares of common stock used in calculating diluted earnings per share is deemed to be increased by the excess, if any, of the number of shares of common stock that would be issued upon full physical settlement of the forward sale agreements over the number of shares of common stock that could be purchased by MAA in the open market (based on the average market price during the period) using the proceeds to be received upon full physical settlement (based on the adjusted forward sale price at the end of the reporting period). When MAA physically or net share settles a forward sale agreement, the delivery of shares of common stock would result in an increase in the number of weighted average common shares outstanding and dilution to basic earnings per share. See Note 8 for additional disclosures regarding equity forward sale agreements.
Revenue Recognition	Revenue Recognition The Company primarily leases multifamily residential apartments to residents under operating leases generally due on a monthly basis with terms of approximately one year or less. Rental revenues are recognized in accordance with ASC Topic 842, Leases , using a method that represents a straight-line basis over the term of the lease. In addition, in circumstances where a lease incentive is provided to residents, the incentive is recognized as a reduction of rental revenues on a straight-line basis over the reasonably assured lease term. Rental revenues represent approximately 94 % of the Company’s total revenues and include gross rents charged less adjustments for concessions and bad debt. Approximately 5 % of the Company’s total revenues represent non-lease reimbursable property revenues from its residents for utility reimbursements, which are generally recognized and due on a monthly basis as residents obtain control of the service over the term of the lease. The remaining 1 % of the Company’s total revenues represents other non-lease property revenues primarily driven by nonrefundable fees and commissions, which are recognized when earned. In accordance with ASC Topic 842, rental revenues and non-lease reimbursable property revenues meet the criteria to be aggregated into a single lease component and are reported on a combined basis in the line item “Rental revenues,” as presented in the disaggregation of the Company’s revenues in Note 13. Other non-lease property revenues are accounted for in accordance with ASC Topic 606, Revenue from Contracts with Customers , which requires revenue recognized outside of the scope of ASC Topic 842 to be recognized when a customer obtains control of promised goods or services in an amount that reflects the consideration the entity expects to receive in exchange for those goods or services. Other non-lease property revenues are reported in the line item “Other property revenues,” as presented in the disaggregation of the Company’s revenues in Note 13.
Advertising Costs	Advertising Costs Costs associated with advertising activities are expensed as incurred and were $ 26.6 million , $ 24.4 million and $ 23.9 million for the years ended December 31, 2023, 2022 and 2021 , respectively.
Leases	Leases The Company is the lessee under certain ground, office, equipment and other operational leases, all of which are accounted for as operating leases in accordance with ASC Topic 842. The Company recognizes a right-of-use asset for the right to use the underlying asset for all leases where the Company is the lessee with terms of more than twelve months, and a related lease liability for the obligation to make lease payments. Expenses related to leases determined to be operating leases are recognized on a straight-line basis. As of December 31, 2023 and 2022 , r ight-of-use assets recorded within “Other assets” totaled $ 42.5 million and $ 44.6 million , respectively, and related lease liabilities recorded within “Accrued expenses and other liabilities” totaled $ 27.3 million and $ 28.7 million , respectively, in the Consolidated Balance Sheets. Lease expense recognized for the years ended December 31, 2023, 2022 and 2021 was immaterial to the Company. Cash paid for amounts included in the measurement of operating lease liabilities during the years ended December 31, 2023 and 2022 was also immaterial. See Note 11 for additional disclosures regarding leases.
Income Taxes	Income Taxes MAA has elected to be taxed as a REIT under the Code 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 requirements with respect to the nature and diversity of MAA’s assets and sources of MAA’s gross income. As long as MAA qualifies for taxation as a REIT, it will generally not be subject to U.S. federal corporate income tax on its taxable income that is currently distributed to shareholders. This treatment substantially eliminates the “double taxation” (i.e., income taxation at both the corporate and shareholder levels) that generally results from an investment in a corporation. Even if MAA qualifies as a REIT, MAA may be subject to U.S. federal income and excise taxes in certain situations, such as if MAA fails to distribute timely all of its taxable income with respect to a taxable year. MAA also will be required to pay a 100% tax on any net income on non-arm’s length transactions between MAA and one of its taxable REIT subsidiaries, or TRS. Furthermore, 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, and the applicable state and local tax laws may not conform to the U.S. federal income tax treatment. Any taxes imposed on MAA would reduce its operating cash flows and net income. The Company has elected TRS status for certain of its corporate subsidiaries. As a result, the TRS incur both federal and state income taxes on any taxable income after consideration of any net operating losses. The TRS use the liability method of accounting for income taxes. Deferred income tax assets and liabilities are recognized for future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities from a change in tax rate is recognized in earnings in the period of the enactment date. A valuation allowance is provided when it is more likely than not that all or some portion of the deferred tax assets will not be realized. 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 likely than not to be realized upon ultimate settlement. See Note 7 for additional disclosures regarding income taxes.
Fair Value Measurements	Fair Value Measurements The Company applies the guidance in ASC Topic 820, Fair Value Measurements and Disclosures , to the valuation of acquired real estate assets recorded at fair value, to its impairment valuation analysis of real estate assets and to its valuation and disclosure of the fair value of financial instruments, which primarily consists of marketable equity securities, indebtedness and derivative instruments. Fair value disclosures required under ASC Topic 820 as well as the Company’s derivative accounting policies are summarized in Note 6 utilizing the following hierarchy: Level 1 - Quoted prices in active markets for identical assets or liabilities that are accessible at the measurement date. Level 2 - Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. Level 3 - Unobservable inputs for the assets or liability.
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.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In 2023, the Financial Accounting Standards Board, or FASB, issued Accounting Standard Update, or ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures , which amends existing accounting standards and establishes new expanded disclosure requirements about a public entity’s reportable segments. Under the new standard, more information will be required regarding a reportable segment’s expenses, interim segment profit or loss, and how a public entity’s chief operating decision maker uses reported segment profit or loss information in assessing segment performance and allocating resources. This ASU is effective for annual periods beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. Management is currently evaluating the impact this standard may have on the consolidated financial statements and related disclosures upon adoption. In 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures , which expands disclosures about federal, state and foreign income taxes in an entity’s income tax rate reconciliation table and regarding cash taxes paid. This ASU is effective for annual periods beginning after December 15, 2024. Management is currently evaluating the impact this standard may have on the consolidated financial statements and related disclosures upon adoption.
