	The Company is the sole general partner of Armada Hoffler, L.P. (the “Operating Partnership”). The operations of the Company are carried on primarily through the Operating Partnership and the wholly owned subsidiaries of the Operating Partnership. Both the Company and the Operating Partnership were formed on October 12, 2012 and commenced operations upon completion of the underwritten initial public offering of shares of the Company’s common stock (the “IPO”) and certain related formation transactions (the “Formation Transactions”) on May 13, 2013.
	Armada Hoffler Properties, Inc. Predecessor (the “Predecessor”) was not a single legal entity, but rather a combination of real estate and construction entities under common ownership by their individual partners, members and stockholders and under common control or significant influence of Daniel A. Hoffler prior to the IPO and the Formation Transactions. The financial position and results of operations of the entities under common control of Mr. Hoffler have been combined in the Predecessor financial statements for the periods prior to the completion of the IPO and the Formation Transactions. The Predecessor accounted for its investments in the entities under significant influence of Mr. Hoffler using the equity method of accounting.
	On May 13, 2013, the Company completed the IPO of 16,525,000 shares of common stock and on May 22, 2013, the underwriters of the IPO exercised their overallotment option in full to purchase an additional 2,478,750 shares. Net proceeds from the IPO to the Company after deducting the underwriting discount and related offering costs were $192.2 million. The Company contributed the net proceeds from the IPO to the Operating Partnership in exchange for common units in the Operating Partnership. With the net proceeds from the IPO, the Operating Partnership repaid $150.0 million of outstanding indebtedness and paid $47.6 million as partial consideration to prior investors in connection with the Formation Transactions.
	Pursuant to the Formation Transactions, the Operating Partnership: (i) acquired 100% of the interests in the entities comprising the Predecessor, (ii) succeeded to the ongoing construction and development businesses of the Predecessor, (iii) assumed asset management of certain of the properties acquired from the Predecessor, (iv) succeeded to the third-party asset management business of the Predecessor, (v) succeeded to the projects under development by the Predecessor, (vi) received options to acquire nine parcels of developable land from the Predecessor and (vii) entered into a contribution agreement to acquire Liberty Apartments upon satisfaction of certain conditions and transferability restrictions including completion of the project’s construction by the Company. The Operating Partnership completed the acquisition of Liberty Apartments on January 17, 2014.
	The Company accounted for the contribution or acquisition of interests in the combined entities of the Predecessor as transactions among entities under common control. As a result, the contribution or acquisition of interests in each of the combined entities was accounted for at the Predecessor’s historical cost. The acquisitions of interests in the equity method investments of the Predecessor were accounted for as purchases at fair value under the acquisition method of accounting.
	References to “Armada Hoffler” in these notes to consolidated and combined financial statements signify the Company for the period after the completion of the IPO and the Formation Transactions on May 13, 2013 and the Predecessor for all prior periods. Because of the timing of the IPO and the Formation Transactions, the results of operations for the year ended December 31, 2012 reflect only those of the Predecessor. The results of operations for the year ended December 31, 2013 reflect those of the Predecessor together with the Company, while the results of operations for the year ended December 31, 2014 as well as the financial condition as of December 31, 2014 and 2013 reflect only those of the Company.

Accounting Policies [Abstract]
Significant Accounting Policies	2	Significant Accounting Policies
	Basis of Presentation
	The accompanying consolidated and combined financial statements were prepared in accordance with accounting principles generally accepted in the United States (“GAAP”).
	The consolidated financial statements include the financial position and results of operations of the Company, the Operating Partnership and its wholly owned subsidiaries. All significant intercompany transactions and balances have been eliminated in consolidation.
	The financial position and results of operations of the entities comprising the Predecessor have been combined because they were under common ownership by their individual partners, members and stockholders and under common control of Mr. Hoffler. All significant intercompany transactions and balances have been eliminated in combination.
	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported and disclosed. Such estimates are based on management’s historical experience and best judgment after considering past, current and expected events and economic conditions. Actual results could differ from management’s estimates.
	Segments
	Segment information is prepared on the same basis that management reviews information for operational decision-making purposes. Management evaluates the performance of each of Armada Hoffler’s properties individually and aggregates such properties into segments based on their economic characteristics and classes of tenants. Armada Hoffler operates in four business segments: (i) office real estate, (ii) retail real estate, (iii) multifamily residential real estate and (iv) general contracting and real estate services. Armada Hoffler’s general contracting and real estate services business develops and builds properties for its own account and also provides construction and development services to both related and third parties.
	Revenue Recognition
	Rental Revenues
	Armada Hoffler leases its properties under operating leases and recognizes base rents when earned on a straight-line basis over the lease term. Armada Hoffler begins recognizing rental revenue when the tenant has the right to take possession of or controls the physical use of the property under lease. The extended collection period for accrued straight-line rental revenue along with Armada Hoffler’s evaluation of tenant credit risk may result in the nonrecognition of all or a portion of straight-line rental revenue until the collection of such revenue is reasonably assured. Armada Hoffler recognizes contingent rental revenue (e.g., percentage rents based on tenant sales) when changes in the factors on which the contingent lease payments are based actually occur. Armada Hoffler recognizes leasing incentives as reductions to rental revenue on a straight-line basis over the lease term. Armada Hoffler recognizes cost reimbursement revenue for real estate taxes, operating expenses and common area maintenance costs on an accrual basis during the periods in which the expenses are incurred. Armada Hoffler recognizes lease termination fees either upon termination or evenly over any remaining lease term.
	General Contracting and Real Estate Services Revenues
	Armada Hoffler recognizes general contracting revenue on construction contracts using the percentage-of-completion method. Under this method, Armada Hoffler recognizes revenue and an estimated profit as construction contract costs are incurred based on the proportion of incurred costs to total estimated construction contract costs at completion. Construction contract costs include all direct material, labor and subcontract costs as well as any indirect costs related to contract performance. Provisions for estimated losses on uncompleted contracts are recognized immediately in the period in which such losses are determined. Changes in job performance, job conditions and estimated profitability, including those arising from contract penalty provisions and final contract settlements, may result in revisions to costs and income and are recognized in the period in which they are determined. Profit incentives are included in revenues when their realization is probable and when they can be reasonably estimated.
	Armada Hoffler recognizes real estate services revenues from property development and management when realized and earned, generally as such services are provided.
	Real Estate Investments
	Income producing property primarily includes land, buildings and tenant improvements and is stated at cost. Real estate investments held for development include land and capitalized development costs. Armada Hoffler reclassifies real estate investments held for development to construction in progress upon commencement of construction. Construction in progress is stated at cost. Direct and certain indirect costs clearly associated with the development, redevelopment, construction, leasing or expansion of real estate assets are capitalized as a cost of the property. Repairs and maintenance costs are expensed as incurred.
	Armada Hoffler capitalizes direct and indirect project costs associated with the initial construction of a property until the property is substantially complete and ready for its intended use. Capitalized project costs include preacquisition development and preconstruction costs including overhead, salaries and related costs of personnel directly involved, real estate taxes, insurance, utilities, ground rent and interest. Interest capitalized during the years ended December 31, 2014 and 2013 was $3.1 million and $0.6 million, respectively. Interest capitalized during the year ended December 31, 2012 was not significant. Overhead, salaries and related personnel costs capitalized during each of the three years ended December 31, 2014 were $2.4 million, $1.6 million and $0.4 million, respectively.
	Armada Hoffler capitalizes preacquisition development costs directly identifiable with specific properties when the acquisition of such properties is probable. Capitalized preacquisition development costs are presented within other assets in the consolidated balance sheets. Capitalized preacquisition development costs as of December 31, 2014 and 2013 were $4.6 million and $2.0 million, respectively. Capitalized preacquisition development costs attributable to the Johns Hopkins Village project were $2.1 million and $0.5 million as of December 31, 2014 and 2013, respectively. Costs attributable to unsuccessful projects are expensed.
	Armada Hoffler recognizes real estate development grants from state and local governments as reductions to the carrying amounts of the related real estate investments when any attached conditions are satisfied and when there is reasonable assurance that the grant will be received.
	Income producing property is depreciated on a straight-line basis over the following estimated useful lives:
	Buildings		39 years
	Capital improvements		15—20 years
	Equipment		5—15 years
	Tenant improvements		Term of the related lease
			(or estimated useful life, if shorter)
	Real Estate Investments Held for Sale
	Real estate assets classified as held for sale are reported at the lower of their carrying value or their fair value, less estimated costs to sell. Once a property is classified as held for sale, it is no longer depreciated. A property is classified as held for sale when: (i) senior management commits to a plan to sell the property, (ii) the property is available for immediate sale in its present condition, subject only to conditions usual and customary for such sales, (iii) an active program to locate a buyer and other actions required to complete the plan to sell have been initiated, (iv) the sale is expected to be completed within one year, (v) the property is being actively marketed for sale at a price that is reasonable in relation to its current fair value and (vi) actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn.
	The Company classified the Sentara Williamsburg office property as held for sale as of December 31, 2014.
	Impairment of Long Lived Assets
	Armada Hoffler evaluates its real estate assets for impairment on a property by property basis whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. If such an evaluation is necessary, Armada Hoffler compares the carrying amount of any such real estate asset with the undiscounted expected future cash flows that are directly associated with, and that are expected to arise as a direct result of, its use and eventual disposition. If the carrying amount of a real estate asset exceeds the associated estimate of undiscounted expected future cash flows, an impairment loss is recognized to reduce the real estate asset’s carrying value to its fair value.
	Cash and Cash Equivalents
	Cash and cash equivalents include demand deposits, investments in money market funds and investments with an original maturity of three months or less.
	Restricted Cash
	Restricted cash represents amounts held by lenders for real estate taxes, insurance and reserves for capital improvements. Armada Hoffler presents changes in cash restricted for real estate taxes and insurance as operating activities in the consolidated and combined statements of cash flows. Armada Hoffler presents changes in cash restricted for capital improvements as investing activities in the consolidated and combined statements of cash flows.
	Accounts Receivable, net
	Accounts receivable include amounts from tenants for base rents, contingent rents and cost reimbursements as well as accrued straight-line rental revenue. As of December 31, 2014 and 2013, accrued straight-line rental revenue presented within accounts receivable in the consolidated balance sheets was $19.4 million and $17.5 million, respectively.
	Armada Hoffler’s evaluation of the collectability of accounts receivable and the adequacy of the allowance for doubtful accounts is based primarily upon evaluations of individual receivables, current economic conditions, historical experience and other relevant factors. Armada Hoffler establishes reserves for tenant receivables outstanding over 90 days. For all such tenants, Armada Hoffler also reserves any related accrued straight-line rental revenue. Additional reserves are recorded for more current amounts, as applicable, when Armada Hoffler has determined collectability to be doubtful. As of December 31, 2014 and 2013, the allowance for doubtful accounts was not significant. Armada Hoffler presents bad debt expense within rental expenses in the consolidated and combined statements of income.
	Leasing Costs
	Commissions paid by Armada Hoffler to third parties to originate a lease are deferred and amortized as depreciation and amortization expense on a straight-line basis over the term of the related lease. Leasing costs are presented within other assets in the consolidated balance sheets.
	Leasing Incentives
	Incentives paid by Armada Hoffler to tenants are deferred and amortized as reductions to rental revenues on a straight-line basis over the term of the related lease. Leasing incentives are presented within other assets in the consolidated balance sheets.
	Acquired Lease Intangibles
	Acquired lease intangibles are presented within other assets and other liabilities in the consolidated balance sheets. The Company amortizes in-place lease assets as depreciation and amortization expense on a straight-line basis over the remaining term of the related leases. The Company amortizes above-market lease assets as reductions to rental revenues on a straight-line basis over the remaining term of the related leases. The Company amortizes below-market lease liabilities as increases to rental revenues on a straight-line basis over the remaining term of the related leases. The Company amortizes below-market ground lease assets as increases to rental expenses on a straight-line basis over the remaining term of the related leases.
	Debt Issuance Costs
	Financing costs are deferred and amortized as interest expense using the effective interest method over the term of the related debt. Debt issuance costs are presented within other assets in the consolidated balance sheets.
	Derivative Financial Instruments
	Armada Hoffler may enter into interest rate derivatives to manage exposure to interest rate risks. Armada Hoffler does not use derivative financial instruments for trading or speculative purposes. Armada Hoffler recognizes derivative financial instruments at fair value and presents them within other assets and liabilities in the consolidated balance sheets. Presentation of gains (losses) resulting from changes in the fair value of derivatives depend on their designation and qualification for hedge accounting. As of December 31, 2014, Armada Hoffler had not designated any of its derivative instruments as hedges for accounting purposes. As a result, changes in the fair value of derivatives have been recognized within other income (expense) in the consolidated and combined statements of income.
	Stock-Based Compensation
	The Company measures the compensation cost of restricted stock awards based on the grant date fair value. The Company recognizes compensation cost for the vesting of restricted stock awards using the accelerated attribution method. Compensation cost associated with the vesting of restricted stock awards is presented within either general and administrative expenses or general contracting and real estate services expenses in the consolidated and combined statements of income. Total stock-based compensation expense recognized during the years ended December 31, 2014 and 2013 was $0.9 million and $1.2 million, respectively. Stock-based compensation for personnel directly involved in the development and initial construction of a property is capitalized. During the year ended December 31, 2014, the Company capitalized $0.4 million of stock-based compensation. Stock-based compensation capitalized during the year ended December 31, 2013 was not significant.
	Income Taxes
	The Company has elected to be taxed as a real estate investment trust (“REIT”) for U.S. federal income tax purposes. For continued qualification as a REIT for federal income tax purposes, the Company must meet certain organizational and operational requirements, including a requirement to pay distributions to stockholders of at least 90% of annual taxable income, excluding net capital gains. As a REIT, the Company generally is not subject to income tax on net income distributed as dividends to stockholders. The Company is subject to state and local income taxes in some jurisdictions and, in certain circumstances, may also be subject to federal excise taxes on undistributed income. In addition, certain of the Company’s activities must be conducted by subsidiaries that have elected to be treated as a taxable REIT subsidiary (“TRS”) subject to both federal and state income taxes. The Operating Partnership conducts its development and construction businesses through the TRS. The related income tax provision or benefit attributable to the profits or losses of the TRS and any taxable income of the Company is reflected in the consolidated and combined financial statements.
	The Company uses the liability method of accounting for deferred income tax in accordance with GAAP. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the carrying value of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using the statutory rates expected to be applied in the periods in which those temporary differences are settled. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in the period of the change. A valuation allowance is recorded on the Company’s deferred tax assets when it is more likely than not that such assets will not be realized. When evaluating the realizability of the Company’s deferred tax assets, all evidence, both positive and negative is evaluated. Items considered in this analysis include the ability to carryback losses, the reversal of temporary differences, tax planning strategies and expectations of future earnings.
	Under GAAP, the amount of tax benefit to be recognized is the amount of benefit that is more likely than not to be sustained upon examination. Management analyzes its tax filing positions in the U.S. federal, state and local jurisdictions where it is required to file income tax returns for all open tax years. If, based on this analysis, management determines that uncertainties in tax positions exist, a liability is established. The Company recognizes accrued interest and penalties related to unrecognized tax positions in the provision for income taxes. If recognized, the entire amount of unrecognized tax positions would be recorded as a reduction to the provision for income taxes.
	The Predecessor was comprised primarily of limited partnerships, limited liability companies and S-corporations. Under applicable federal and state income tax rules, the allocated share of net income or loss from limited partnerships, limited liability companies and S-corporations flows through to the respective partners, members and shareholders. For periods prior to the completion of the IPO and the Formation Transactions on May 13, 2013, no provision was made for U.S. federal, state or local income taxes because profits and losses of the Predecessor flowed through to its respective partners, members and shareholders that were individually responsible for reporting such amounts.
	Discontinued Operations
	For periods prior to January 1, 2014, Armada Hoffler presented properties held for sale as discontinued operations only when it would not have any significant continuing involvement in the properties’ operations after their disposition and when the properties’ operations and cash flows: (i) could be clearly distinguished and (ii) would be eliminated from Armada Hoffler’s ongoing operations upon disposition.
	Beginning January 1, 2014, only disposals representing a strategic shift that has or will have a major effect on the Company’s operations and financial results are reported as discontinued operations.
	Net Income Per Share and Unit
	The Company calculates net income per share and unit based upon the weighted average shares and units outstanding for periods after the completion of the IPO and Formation Transactions on May 13, 2013. Diluted net income per share and unit is calculated after giving effect to all significant potential dilutive shares outstanding during the period. There were no significant potential dilutive shares or units outstanding during the period May 13, 2013 through December 31, 2013 or for the year ended December 31, 2014. As a result, basic and diluted outstanding shares and units were the same.
	Other Comprehensive Income
	Armada Hoffler had no items of other comprehensive income during any of the three years ended December 31, 2014.
	Emerging Growth Company Status
	The Company qualifies as an emerging growth company (“EGC”) pursuant to the Jumpstart Our Business Startups Act. An EGC may choose to take advantage of the extended private company transition period provided for complying with new or revised accounting standards that may be issued by the Financial Accounting Standards Board (the “FASB”) or the U.S. Securities and Exchange Commission (the “SEC”). The Company has elected to opt out of such extended transition period. This election is irrevocable.
Recent Accounting Pronouncements
In April 2014, the FASB revised the reporting and disclosure guidance for discontinued operations. Under the revised guidance, only disposals representing a strategic shift that has or will have a major effect on the Company’s operations and financial results will be reported as discontinued operations. The revised guidance also expands the disclosure requirements for discontinued operations and other disposals of significant business components. The revised guidance is not effective for the Company until January 1, 2015; however, early adoption is permitted. The Company early adopted the revised guidance effective January 1, 2014.
In May 2014, the FASB issued a new standard that provides a single, comprehensive model for recognizing revenue from contracts with customers. While the new standard does not supersede the guidance on accounting for leases, it could change the way the Company recognizes revenue from construction and development contracts with third-party customers. The new standard will be effective for the Company beginning on January 1, 2017. Early adoption is not permitted. Management is currently evaluating the potential impact of the new revenue recognition standard on the Company’s consolidated financial statements.

Segment Reporting [Abstract]
Segments	3	Segments
	Net operating income (segment revenues minus segment expenses) is the measure used by Armada Hoffler’s chief operating decision-maker to assess segment performance. Net operating income is not a measure of operating income or cash flows from operating activities as measured by GAAP and is not indicative of cash available to fund cash needs. As a result, net operating income should not be considered an alternative to cash flows as a measure of liquidity. Not all companies calculate net operating income in the same manner. Armada Hoffler considers net operating income to be an appropriate supplemental measure to net income because it assists both investors and management in understanding the core operations of Armada Hoffler’s real estate and construction businesses.
	Net operating income of Armada Hoffler’s reportable segments for each of the three years ended December 31, 2014 was as follows (in thousands):

	Construction contract costs and estimated earnings in excess of billings represent reimbursable costs and amounts earned under contracts in progress as of the balance sheet date. Such amounts become billable according to contract terms, which usually consider the passage of time, achievement of certain milestones or completion of the project. Billings of $39.8 million and $16.2 million are netted against construction contract costs and estimated earnings as of December 31, 2014 and 2013, respectively. The Company expects to bill and collect substantially all construction contract costs incurred as of December 31, 2014 during the year ending December 31, 2015.

Credit Facility
On May 13, 2013, the Operating Partnership, as borrower, and the Company, as parent guarantor, entered into a $100.0 million senior secured revolving credit facility. On October 10, 2013, the Operating Partnership increased the aggregate capacity under the credit facility to $155.0 million. As of December 31, 2013, the Operating Partnership had $70.0 million outstanding under the credit facility. During the year ended December 31, 2014, the Operating Partnership borrowed $38.0 million under the credit facility. On September 15, 2014, the Operating Partnership used the proceeds from the Company’s underwritten public offering of common stock to repay $49.0 million of the outstanding balance under the credit facility that had been used to fund the Company’s development activities. As of December 31, 2014, the Operating Partnership had $59.0 million outstanding on the credit facility.
As of December 31, 2014, the following properties served as the borrowing base collateral for the credit facility: (i) Armada Hoffler Tower, (ii) Richmond Tower, (iii) One Columbus, (iv) Two Columbus, (v) Sentara Williamsburg, (vi) Bermuda Crossroads, (vii) a portion of North Point Center, (viii) Gainsborough Square, (ix) Parkway Marketplace and (x) Courthouse 7-Eleven.
The credit facility required the Operating Partnership to comply with various financial covenants, including:
	•		Maximum leverage ratio (as amended on April 22, 2014) of 65% as of the last day of each fiscal quarter through maturity;
	•		Minimum fixed charge coverage ratio of 1.75 to 1.0;
	•		Minimum tangible net worth equal to at least the sum of 80% of tangible net worth on the closing date of the credit facility plus 75% of the net proceeds of any additional equity issuances;
	•		Maximum amount of variable rate indebtedness not exceeding 30% of total asset value; and
	•		Maximum amount of secured recourse indebtedness of 35% of total asset value.
The credit facility permitted investments in the following types of assets: (i) unimproved land holdings in an aggregate amount not exceeding 5% of total asset value, (ii) construction in progress in an aggregate amount not exceeding 25% of total asset value and (iii) unconsolidated affiliates in aggregate amount not exceeding 5% of total asset value. Investments in these types of assets collectively could not exceed 30% of total asset value. In addition to these financial covenants, the credit facility required the Operating Partnership to comply with various customary affirmative and negative covenants that restricted the ability to, among other things, incur debt and liens, make investments, dispose of properties and make distributions. As of December 31, 2014, the Operating Partnership was in compliance with all covenants under the credit facility.
The credit facility bore interest between LIBOR plus 1.60% and LIBOR plus 2.20%. The interest rate on the credit facility as of December 31, 2014 was 1.92%.
Subsequent to December 31, 2014
On January 23, 2015, the Operating Partnership borrowed an additional $5.0 million under the credit facility. The credit facility was scheduled to mature on May 13, 2016; however, the Operating Partnership repaid all amounts due under the credit facility with proceeds from a new credit facility and terminated the existing credit facility on February 20, 2015, as discussed below.
New Credit Facility
On February 20, 2015, the Operating Partnership, as borrower, and the Company as parent guarantor, agreed to a new $200.0 million senior unsecured credit facility that includes a $150.0 million senior unsecured revolving credit facility and a $50.0 million senior unsecured term loan facility. The new credit facility replaced the existing $155.0 million senior secured revolving credit facility that was scheduled to mature on May 13, 2016. On February 20, 2015, the Operating Partnership borrowed $54.0 million under the revolving credit facility and $50.0 million under the term loan facility to repay in full all outstanding amounts due under the prior credit facility and to repay approximately $39.0 million of other indebtedness secured by properties in the Company’s portfolio for the purpose of unencumbering those properties.
The new credit facility includes an accordion feature that allows the total commitments to be increased to $350.0 million, subject to certain conditions. The amount permitted to be borrowed under the new credit facility, together with all of the Operating Partnership’s other unsecured indebtedness is generally limited to the lesser of: (i) 60% of the value of the unencumbered borrowing base properties, (ii) the maximum amount of principal that would result in a debt service coverage ratio of 1.50 to 1.0, and (iii) the maximum aggregate loan commitment, which currently is $200.0 million.
The new revolving credit facility has a scheduled maturity date of February 20, 2019, with a one-year extension option. The term loan facility has a scheduled maturity date of February 20, 2020. The Operating Partnership may, at any time, voluntarily prepay any loan under the new credit facility in whole or in part without premium or penalty.
The new revolving credit facility bears interest at LIBOR plus 1.40% to 2.00%, depending on the Operating Partnership’s total leverage. The term loan facility bears interest at LIBOR plus 1.35% to 1.95%, depending on the Operating Partnership’s total leverage. The Operating Partnership is also obligated to pay an unused commitment fee of 15 or 25 basis points on the unused portions of the commitments under the new credit facility, depending on the amount of borrowings under the new credit facility. If the Company attains investment grade credit ratings from S&P and Moody’s, the Operating Partnership may elect to have borrowings become subject to interest rates based on such credit ratings.
The new credit facility requires the Operating Partnership to comply with various financial covenants, affirmative covenants and other restrictions, including the following:
	•		Total leverage ratio of the Company of not more than 60%;
	•		Ratio of adjusted EBITDA to fixed charges of the Company of not less than 1.50 to 1.0;
	•		Tangible net worth of not less than the sum of $220.0 million and 75% of the net equity proceeds received after December 31, 2014;
	•		Ratio of variable rate indebtedness to total asset value of not more than 30%;
	•		Ratio of secured indebtedness to total asset value of not more than 45%; and
	•		Ratio of secured recourse debt to total asset value of not more than 25%.
The new credit facility limits the Company’s ability to pay cash dividends. However, so long as no default or event of default exists, the credit agreement allows the Company to pay cash dividends with respect to any 12-month period in an amount not to exceed the greater of: (i) 95% of adjusted funds from operations (as defined in the credit agreement) or (ii) the amount required for the Company (a) to maintain its status as a REIT and (b) to avoid income or excise tax. If certain defaults or events of default exist, the Company may pay cash dividends with respect to any 12-month period to the extent necessary to maintain its status as a REIT. The new credit facility also restricts the amount of capital that the Operating Partnership can invest in specific categories of assets, such as unimproved land holdings, development properties, notes receivable, mortgages, mezzanine loans and unconsolidated affiliates.
Other Financing Activity
On January 17, 2014, the Company assumed $17.0 million of debt at fair value in connection with the acquisition of Liberty Apartments. The fair value adjustment to the assumed debt of Liberty Apartments was a $1.5 million discount. The outstanding principal balance of the assumed debt of Liberty Apartments at the acquisition date was $18.5 million. On June 13, 2014, the Company borrowed the remaining $2.4 million available under the Liberty Apartments loan. The loan amortizes over 30 years, bears interest at 5.66% and matures on November 1, 2043.
On February 28, 2014, the Company closed on a $19.5 million loan to fund the development and construction of the Oceaneering International facility. The construction loan bears interest at LIBOR plus 1.75% and matures on February 28, 2018.
On August 15, 2014, the Company defeased the loan secured by Dimmock Square for $10.1 million.
On August 28, 2014, the Company closed on a $5.4 million loan to fund the development and construction of a new administrative building for the Commonwealth of Virginia. The construction loan bears interest at LIBOR plus 1.90% and matures on August 28, 2017.

On November 14, 2014, the Company closed on a $15.0 million loan to fund the development and construction of Lightfoot Marketplace. The construction loan bears interest at LIBOR plus 1.90% and matures on November 14, 2017.
Subsequent to December 31, 2014
On February 20, 2015, the Company repaid the following loans with borrowings under the Operating Partnership’s new credit facility: (i) Studio 56 Retail, (ii) Commerce Street Retail, (iii) Dick’s at Town Center, (iv) Broad Creek Shopping Center Note 1, (v) Broad Creek Shopping Center Note 2, (vi) Broad Creek Shopping Center Note 3, (vii) Hanbury Village Note 2 and (viii) Tyre Neck Harris Teeter.

	Noncontrolling Interests
	As of December 31, 2014 and 2013, the Company held a 62.9% and 59.5% interest in the Operating Partnership, respectively.

On March 31, 2014, the Operating Partnership issued 30,000 OP Units in exchange for all noncontrolling interests in Sandbridge Commons.

On August 15, 2014, the Operating Partnership issued 990,952 OP Units as partial consideration for the acquisition of Dimmock Square.
	Holders of OP Units may not transfer their units without the Company’s prior consent as general partner of the Operating Partnership.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	11	Fair Value of Financial Instruments
	Fair value measurements are based on assumptions that market participants would use in pricing an asset or a liability. The hierarchy for inputs used in measuring fair value is as follows:
	Level 1 Inputs—quoted prices in active markets for identical assets or liabilities
	Level 2 Inputs—observable inputs other than quoted prices in active markets for identical assets and liabilities
	Level 3 Inputs—unobservable inputs
	Except as disclosed below, the carrying amounts of the Company’s financial instruments approximate their fair value. Financial assets and liabilities whose fair values are measured on a recurring basis using Level 2 inputs consist of interest rate swaps and interest rate caps. The Company measures the fair values of these assets and liabilities based on prices provided by independent market participants that are based on observable inputs using market-based valuation techniques.
	In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. For disclosure purposes, the level within which the fair value measurement is categorized is based on the lowest level input that is significant to the fair value measurement.
	The fair value of the Company’s secured debt is sensitive to fluctuations in interest rates. Discounted cash flow analysis based on Level 2 inputs is generally used to estimate the fair value of the Company’s secured debt.

	Legal Proceedings
	The Company is from time to time involved in various disputes, lawsuits, warranty claims, environmental and other matters arising in the ordinary course of its business. Management makes assumptions and estimates concerning the likelihood and amount of any potential loss relating to these matters.
	The Company currently is a party to various legal proceedings, none of which management expects will have a material adverse effect on the Company’s financial position, results of operations or liquidity. Management accrues a liability for litigation if an unfavorable outcome is determined to be probable and the amount of loss can be reasonably estimated. If an unfavorable outcome is determined by management to be probable and a range of loss can be reasonably estimated, management accrues the best estimate within the range; however, if no amount within the range is a better estimate than any other, the minimum amount within the range is accrued. Legal fees related to litigation are expensed as incurred. Management does not believe that the ultimate outcome of these matters, either individually or in the aggregate, could have a material adverse effect on the Company’s financial position or results of operations; however, litigation is subject to inherent uncertainties.
	Under the Company’s leases, tenants are typically obligated to indemnify the Company from and against all liabilities, costs and expenses imposed upon or asserted against it as owner of the properties due to certain matters relating to the operation of the properties by the tenant.
	Commitments

Such bonds collectively totaled $192.2 million and $35.8 million as of December 31, 2014 and 2013, respectively.
	The Operating Partnership has entered into standby letters of credit using the available capacity under the credit facility. The letters of credit relate to the guarantee of future performance on certain of the Company’s construction contracts. Letters of credit generally are available for draw down in the event the Company does not perform. As of December 31, 2014 and 2013, the Operating Partnership had total outstanding letters of credit of $8.5 million and $3.0 million, respectively.
	The Company has four ground leases on three properties with initial terms that range from twenty to fifty years and options to extend up to an additional 40 years in certain cases. The Company also leases automobiles and equipment.

For each of the three years ended December 31, 2014, rental revenues from Hampton Roads properties represented 69%, 70% and 75%, respectively, of Armada Hoffler’s rental revenues. Many of Armada Hoffler’s Hampton Roads properties are located in the Town Center of Virginia Beach. For each of the three years ended December 31, 2014, rental revenues from Town Center properties represented 47%, 48% and 51%, respectively, of Armada Hoffler’s rental revenues.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation
	The accompanying consolidated and combined financial statements were prepared in accordance with accounting principles generally accepted in the United States (“GAAP”).
	The consolidated financial statements include the financial position and results of operations of the Company, the Operating Partnership and its wholly owned subsidiaries. All significant intercompany transactions and balances have been eliminated in consolidation.
	The financial position and results of operations of the entities comprising the Predecessor have been combined because they were under common ownership by their individual partners, members and stockholders and under common control of Mr. Hoffler. All significant intercompany transactions and balances have been eliminated in combination.
Use of Estimates	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported and disclosed. Such estimates are based on management’s historical experience and best judgment after considering past, current and expected events and economic conditions. Actual results could differ from management’s estimates.
Segments	Segments
	Segment information is prepared on the same basis that management reviews information for operational decision-making purposes. Management evaluates the performance of each of Armada Hoffler’s properties individually and aggregates such properties into segments based on their economic characteristics and classes of tenants. Armada Hoffler operates in four business segments: (i) office real estate, (ii) retail real estate, (iii) multifamily residential real estate and (iv) general contracting and real estate services. Armada Hoffler’s general contracting and real estate services business develops and builds properties for its own account and also provides construction and development services to both related and third parties.
Revenue Recognition	Revenue Recognition
	Rental Revenues
	Armada Hoffler leases its properties under operating leases and recognizes base rents when earned on a straight-line basis over the lease term. Armada Hoffler begins recognizing rental revenue when the tenant has the right to take possession of or controls the physical use of the property under lease. The extended collection period for accrued straight-line rental revenue along with Armada Hoffler’s evaluation of tenant credit risk may result in the nonrecognition of all or a portion of straight-line rental revenue until the collection of such revenue is reasonably assured. Armada Hoffler recognizes contingent rental revenue (e.g., percentage rents based on tenant sales) when changes in the factors on which the contingent lease payments are based actually occur. Armada Hoffler recognizes leasing incentives as reductions to rental revenue on a straight-line basis over the lease term. Armada Hoffler recognizes cost reimbursement revenue for real estate taxes, operating expenses and common area maintenance costs on an accrual basis during the periods in which the expenses are incurred. Armada Hoffler recognizes lease termination fees either upon termination or evenly over any remaining lease term.
	General Contracting and Real Estate Services Revenues
	Armada Hoffler recognizes general contracting revenue on construction contracts using the percentage-of-completion method. Under this method, Armada Hoffler recognizes revenue and an estimated profit as construction contract costs are incurred based on the proportion of incurred costs to total estimated construction contract costs at completion. Construction contract costs include all direct material, labor and subcontract costs as well as any indirect costs related to contract performance. Provisions for estimated losses on uncompleted contracts are recognized immediately in the period in which such losses are determined. Changes in job performance, job conditions and estimated profitability, including those arising from contract penalty provisions and final contract settlements, may result in revisions to costs and income and are recognized in the period in which they are determined. Profit incentives are included in revenues when their realization is probable and when they can be reasonably estimated.
	Armada Hoffler recognizes real estate services revenues from property development and management when realized and earned, generally as such services are provided.
Real Estate Investments	Real Estate Investments
	Income producing property primarily includes land, buildings and tenant improvements and is stated at cost. Real estate investments held for development include land and capitalized development costs. Armada Hoffler reclassifies real estate investments held for development to construction in progress upon commencement of construction. Construction in progress is stated at cost. Direct and certain indirect costs clearly associated with the development, redevelopment, construction, leasing or expansion of real estate assets are capitalized as a cost of the property. Repairs and maintenance costs are expensed as incurred.
	Armada Hoffler capitalizes direct and indirect project costs associated with the initial construction of a property until the property is substantially complete and ready for its intended use. Capitalized project costs include preacquisition development and preconstruction costs including overhead, salaries and related costs of personnel directly involved, real estate taxes, insurance, utilities, ground rent and interest. Interest capitalized during the years ended December 31, 2014 and 2013 was $3.1 million and $0.6 million, respectively. Interest capitalized during the year ended December 31, 2012 was not significant. Overhead, salaries and related personnel costs capitalized during each of the three years ended December 31, 2014 were $2.4 million, $1.6 million and $0.4 million, respectively.
	Armada Hoffler capitalizes preacquisition development costs directly identifiable with specific properties when the acquisition of such properties is probable. Capitalized preacquisition development costs are presented within other assets in the consolidated balance sheets. Capitalized preacquisition development costs as of December 31, 2014 and 2013 were $4.6 million and $2.0 million, respectively. Capitalized preacquisition development costs attributable to the Johns Hopkins Village project were $2.1 million and $0.5 million as of December 31, 2014 and 2013, respectively. Costs attributable to unsuccessful projects are expensed.
	Armada Hoffler recognizes real estate development grants from state and local governments as reductions to the carrying amounts of the related real estate investments when any attached conditions are satisfied and when there is reasonable assurance that the grant will be received.
	Income producing property is depreciated on a straight-line basis over the following estimated useful lives:
	Buildings	39 years
	Capital improvements	15—20 years
	Equipment	5—15 years
	Tenant improvements	Term of the related lease
		(or estimated useful life, if shorter)
Real Estate Investments Held for Sale	Real Estate Investments Held for Sale
	Real estate assets classified as held for sale are reported at the lower of their carrying value or their fair value, less estimated costs to sell. Once a property is classified as held for sale, it is no longer depreciated. A property is classified as held for sale when: (i) senior management commits to a plan to sell the property, (ii) the property is available for immediate sale in its present condition, subject only to conditions usual and customary for such sales, (iii) an active program to locate a buyer and other actions required to complete the plan to sell have been initiated, (iv) the sale is expected to be completed within one year, (v) the property is being actively marketed for sale at a price that is reasonable in relation to its current fair value and (vi) actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn.
	The Company classified the Sentara Williamsburg office property as held for sale as of December 31, 2014.
Impairment of Long Lived Assets	Impairment of Long Lived Assets
	Armada Hoffler evaluates its real estate assets for impairment on a property by property basis whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. If such an evaluation is necessary, Armada Hoffler compares the carrying amount of any such real estate asset with the undiscounted expected future cash flows that are directly associated with, and that are expected to arise as a direct result of, its use and eventual disposition. If the carrying amount of a real estate asset exceeds the associated estimate of undiscounted expected future cash flows, an impairment loss is recognized to reduce the real estate asset’s carrying value to its fair value.
Cash and Cash Equivalents	Cash and Cash Equivalents
	Cash and cash equivalents include demand deposits, investments in money market funds and investments with an original maturity of three months or less.
Restricted Cash	Restricted Cash
	Restricted cash represents amounts held by lenders for real estate taxes, insurance and reserves for capital improvements. Armada Hoffler presents changes in cash restricted for real estate taxes and insurance as operating activities in the consolidated and combined statements of cash flows. Armada Hoffler presents changes in cash restricted for capital improvements as investing activities in the consolidated and combined statements of cash flows.
Accounts Receivable, net	Accounts Receivable, net
	Accounts receivable include amounts from tenants for base rents, contingent rents and cost reimbursements as well as accrued straight-line rental revenue. As of December 31, 2014 and 2013, accrued straight-line rental revenue presented within accounts receivable in the consolidated balance sheets was $19.4 million and $17.5 million, respectively.
	Armada Hoffler’s evaluation of the collectability of accounts receivable and the adequacy of the allowance for doubtful accounts is based primarily upon evaluations of individual receivables, current economic conditions, historical experience and other relevant factors. Armada Hoffler establishes reserves for tenant receivables outstanding over 90 days. For all such tenants, Armada Hoffler also reserves any related accrued straight-line rental revenue. Additional reserves are recorded for more current amounts, as applicable, when Armada Hoffler has determined collectability to be doubtful. As of December 31, 2014 and 2013, the allowance for doubtful accounts was not significant. Armada Hoffler presents bad debt expense within rental expenses in the consolidated and combined statements of income.
Leasing Costs	Leasing Costs
	Commissions paid by Armada Hoffler to third parties to originate a lease are deferred and amortized as depreciation and amortization expense on a straight-line basis over the term of the related lease. Leasing costs are presented within other assets in the consolidated balance sheets.
Leasing Incentives	Leasing Incentives
	Incentives paid by Armada Hoffler to tenants are deferred and amortized as reductions to rental revenues on a straight-line basis over the term of the related lease. Leasing incentives are presented within other assets in the consolidated balance sheets.
Acquired Lease Intangibles	Acquired Lease Intangibles
	Acquired lease intangibles are presented within other assets and other liabilities in the consolidated balance sheets. The Company amortizes in-place lease assets as depreciation and amortization expense on a straight-line basis over the remaining term of the related leases. The Company amortizes above-market lease assets as reductions to rental revenues on a straight-line basis over the remaining term of the related leases. The Company amortizes below-market lease liabilities as increases to rental revenues on a straight-line basis over the remaining term of the related leases. The Company amortizes below-market ground lease assets as increases to rental expenses on a straight-line basis over the remaining term of the related leases.
Debt Issuance Costs	Debt Issuance Costs
	Financing costs are deferred and amortized as interest expense using the effective interest method over the term of the related debt. Debt issuance costs are presented within other assets in the consolidated balance sheets.
Derivative Financial Instruments	Derivative Financial Instruments
	Armada Hoffler may enter into interest rate derivatives to manage exposure to interest rate risks. Armada Hoffler does not use derivative financial instruments for trading or speculative purposes. Armada Hoffler recognizes derivative financial instruments at fair value and presents them within other assets and liabilities in the consolidated balance sheets. Presentation of gains (losses) resulting from changes in the fair value of derivatives depend on their designation and qualification for hedge accounting. As of December 31, 2014, Armada Hoffler had not designated any of its derivative instruments as hedges for accounting purposes. As a result, changes in the fair value of derivatives have been recognized within other income (expense) in the consolidated and combined statements of income.
Stock Based Compensation	Stock-Based Compensation
	The Company measures the compensation cost of restricted stock awards based on the grant date fair value. The Company recognizes compensation cost for the vesting of restricted stock awards using the accelerated attribution method. Compensation cost associated with the vesting of restricted stock awards is presented within either general and administrative expenses or general contracting and real estate services expenses in the consolidated and combined statements of income. Total stock-based compensation expense recognized during the years ended December 31, 2014 and 2013 was $0.9 million and $1.2 million, respectively. Stock-based compensation for personnel directly involved in the development and initial construction of a property is capitalized. During the year ended December 31, 2014, the Company capitalized $0.4 million of stock-based compensation. Stock-based compensation capitalized during the year ended December 31, 2013 was not significant.
Income Taxes	Income Taxes
	The Company has elected to be taxed as a real estate investment trust (“REIT”) for U.S. federal income tax purposes. For continued qualification as a REIT for federal income tax purposes, the Company must meet certain organizational and operational requirements, including a requirement to pay distributions to stockholders of at least 90% of annual taxable income, excluding net capital gains. As a REIT, the Company generally is not subject to income tax on net income distributed as dividends to stockholders. The Company is subject to state and local income taxes in some jurisdictions and, in certain circumstances, may also be subject to federal excise taxes on undistributed income. In addition, certain of the Company’s activities must be conducted by subsidiaries that have elected to be treated as a taxable REIT subsidiary (“TRS”) subject to both federal and state income taxes. The Operating Partnership conducts its development and construction businesses through the TRS. The related income tax provision or benefit attributable to the profits or losses of the TRS and any taxable income of the Company is reflected in the consolidated and combined financial statements.
	The Company uses the liability method of accounting for deferred income tax in accordance with GAAP. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the carrying value of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using the statutory rates expected to be applied in the periods in which those temporary differences are settled. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in the period of the change. A valuation allowance is recorded on the Company’s deferred tax assets when it is more likely than not that such assets will not be realized. When evaluating the realizability of the Company’s deferred tax assets, all evidence, both positive and negative is evaluated. Items considered in this analysis include the ability to carryback losses, the reversal of temporary differences, tax planning strategies and expectations of future earnings.
	Under GAAP, the amount of tax benefit to be recognized is the amount of benefit that is more likely than not to be sustained upon examination. Management analyzes its tax filing positions in the U.S. federal, state and local jurisdictions where it is required to file income tax returns for all open tax years. If, based on this analysis, management determines that uncertainties in tax positions exist, a liability is established. The Company recognizes accrued interest and penalties related to unrecognized tax positions in the provision for income taxes. If recognized, the entire amount of unrecognized tax positions would be recorded as a reduction to the provision for income taxes.
	The Predecessor was comprised primarily of limited partnerships, limited liability companies and S-corporations. Under applicable federal and state income tax rules, the allocated share of net income or loss from limited partnerships, limited liability companies and S-corporations flows through to the respective partners, members and shareholders. For periods prior to the completion of the IPO and the Formation Transactions on May 13, 2013, no provision was made for U.S. federal, state or local income taxes because profits and losses of the Predecessor flowed through to its respective partners, members and shareholders that were individually responsible for reporting such amounts.
Discontinued Operations	Discontinued Operations
	For periods prior to January 1, 2014, Armada Hoffler presented properties held for sale as discontinued operations only when it would not have any significant continuing involvement in the properties’ operations after their disposition and when the properties’ operations and cash flows: (i) could be clearly distinguished and (ii) would be eliminated from Armada Hoffler’s ongoing operations upon disposition.
	Beginning January 1, 2014, only disposals representing a strategic shift that has or will have a major effect on the Company’s operations and financial results are reported as discontinued operations.
Net Income Per Share and Unit	Net Income Per Share and Unit
	The Company calculates net income per share and unit based upon the weighted average shares and units outstanding for periods after the completion of the IPO and Formation Transactions on May 13, 2013. Diluted net income per share and unit is calculated after giving effect to all significant potential dilutive shares outstanding during the period. There were no significant potential dilutive shares or units outstanding during the period May 13, 2013 through December 31, 2013 or for the year ended December 31, 2014. As a result, basic and diluted outstanding shares and units were the same.
Other Comprehensive Income	Other Comprehensive Income
	Armada Hoffler had no items of other comprehensive income during any of the three years ended December 31, 2014.
Emerging Growth Company Status	Emerging Growth Company Status
	The Company qualifies as an emerging growth company (“EGC”) pursuant to the Jumpstart Our Business Startups Act. An EGC may choose to take advantage of the extended private company transition period provided for complying with new or revised accounting standards that may be issued by the Financial Accounting Standards Board (the “FASB”) or the U.S. Securities and Exchange Commission (the “SEC”). The Company has elected to opt out of such extended transition period. This election is irrevocable.
Recent Accounting Pronouncements	Recent Accounting Pronouncements
	In April 2014, the FASB revised the reporting and disclosure guidance for discontinued operations. Under the revised guidance, only disposals representing a strategic shift that has or will have a major effect on the Company’s operations and financial results will be reported as discontinued operations. The revised guidance also expands the disclosure requirements for discontinued operations and other disposals of significant business components. The revised guidance is not effective for the Company until January 1, 2015; however, early adoption is permitted. The Company early adopted the revised guidance effective January 1, 2014.
	In May 2014, the FASB issued a new standard that provides a single, comprehensive model for recognizing revenue from contracts with customers. While the new standard does not supersede the guidance on accounting for leases, it could change the way the Company recognizes revenue from construction and development contracts with third-party customers. The new standard will be effective for the Company beginning on January 1, 2017. Early adoption is not permitted. Management is currently evaluating the potential impact of the new revenue recognition standard on the Company’s consolidated financial statements.
