Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies Basis of Presentation The accompanying consolidated 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, its wholly owned subsidiaries, and any interests in variable interest entities ("VIEs") where the Company has been determined to be the primary beneficiary. All significant intercompany transactions and balances have been eliminated in consolidation. 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 the Company’s properties individually and aggregates such properties into segments based on their economic characteristics and classes of tenants. The Company 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. The Company’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. Reclassifications Certain amounts previously reported in the consolidated financial statements have been reclassified in the accompanying consolidated financial statements to conform to the current period's presentation. The Company has included gain on real estate dispositions as a component of operating income to present gain on real estate dispositions in accordance with ASC 360-10-45-5. The change was made for the prior periods as the Securities and Exchange Commission has eliminated Rule 3-15(a) of Regulation S-X, which had required REIT's to present gains and losses on sale of properties outside of continuing operations in the income statement. The rule change is effective for all filings made on or after November 5, 2018. During the second quarter of 2018, the Company identified certain immaterial classification errors on the Company's Consolidated Statements of Cash Flows and determined that, in the Quarterly Report on Form 10-Q for the quarter ended June 30, 2018 and future periodic reports, the Company would correct these classification errors. One classification error was corrected by including within the changes in operating assets and liabilities in the operating activities section a new line item for "Interest receivable." A corresponding adjustment was recorded to reduce the amount of "Notes receivable issuances" within investing activities on the consolidated statement of cash flows. These reclassifications totaled $7.1 million and $3.2 million during the years ended December 31, 2017 and 2016, respectively. These reclassifications decreased "Net cash provided by operating activities" and "Net cash used for investing activities" by an equal and offsetting amount. These reclassifications did not have any impact on the Consolidated Balance Sheets, Consolidated Statements of Comprehensive Income, Consolidated Statement of Equity, or any other operating measure for the periods affected. These amounts were previously presented as "Notes receivable issuances," a component of net cash used for investing activities on the Consolidated Statements of Cash Flows, resulting in overstatements in cash provided by operating activities and overstatements of cash used in investing activities. These amounts represent interest earned on mezzanine loans that were funded by additional borrowings as provided for in the mezzanine loan agreements. These amounts are now classified as changes in interest receivable, a non-cash adjustment to calculate net cash provided by operating activities. The second classification error was corrected by including within financing activities on the Consolidated Statements of Cash Flows a new line item for “Common shares tendered for tax withholding.” A corresponding adjustment was recorded to the "Changes in operating assets and liabilities: Property liabilities" within operating activities on the Consolidated Statements of Cash Flows. This reclassification totaled $0.3 million and $0.2 million during the years ended December 31, 2017 and 2016, respectively. These reclassifications increased “Net cash provided by operating activities” and decreased “Net cash provided by financing activities” by an equal and offsetting amount. Revenue Recognition Rental Revenues The Company leases its properties under operating leases and recognizes base rents when earned on a straight-line basis over the lease term. Rental revenues include $2.7 million , $1.2 million and $1.1 million of straight-line rent adjustments for the years ended December 31, 2018 , 2017 , and 2016 , respectively. The Company 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 the Company’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 probable. The Company recognizes contingent rental revenue (e.g., percentage rents based on tenant sales thresholds) when the sales thresholds are met. Contingent rents included in rental revenues were $0.3 million , $0.4 million , and $0.4 million for the years ended December 31, 2018 , 2017 , and 2016 , respectively. The Company recognizes leasing incentives as reductions to rental revenue on a straight-line basis over the lease term. Leasing incentive amortization was $0.7 million , $0.8 million , and $0.8 million for the years ended December 31, 2018 , 2017 , and 2016 , respectively. The Company recognizes fair value adjustments recorded at the time of lease assumption in rental income on a straight line basis as a reduction to revenue over the remaining life of the lease or any renewal periods for which the Company determines have value at the time of acquisition. The Company 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. The Company recognizes lease termination fees either upon termination or amortizes them over any remaining lease term. General Contracting and Real Estate Services Revenues On May 28, 2014, the Financial Accounting Standards Board ("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 changes the way the Company recognizes revenue from construction and development contracts with third party customers. The Company adopted this standard on January 1, 2018 using the modified retrospective method, applying this standard to all contracts not yet completed as of that date. In applying the standard to the Company’s future construction contracts, certain pre-contract costs incurred by the Company are now deferred and amortized over the period during which construction obligations are fulfilled. Previously, these costs were immediately recorded as general contracting expenses upon commencement of construction, with the corresponding general contracting revenue also recorded. Applying the standard to the Company’s uncompleted contracts as of January 1, 2018 did not result in material differences to these contracts in aggregate, and no cumulative adjustment to distributions in excess of earnings was recorded as of January 1, 2018. The Company recognizes general contracting revenues as a customer obtains control of promised goods or services in an amount that reflects the consideration the Company expects to receive in exchange for those goods or services. For each construction contract, the Company identifies the performance obligations, which typically include the delivery of a single building constructed according to the specifications of the contract. The Company estimates the total transaction price, which generally includes a fixed contract price and may also include variable components such as early completion bonuses, liquidated damages, or cost savings to be shared with the customer. Variable components of the contract price are included in the transaction price to the extent that it is probable that a significant reversal of revenue will not occur. The Company recognizes the estimated transaction price as revenue as it satisfies its performance obligations; the Company estimates its progress in satisfying performance obligations for each contract using the input method, based on the proportion of incurred costs relative to total estimated construction costs at completion. Construction contract costs include all direct material, direct labor, subcontract costs, and overhead costs directly related to contract performance. Changes in job performance, job conditions, and estimated profitability, including those arising from contract penalty provisions and final contract settlements, are all significant judgments that may result in revisions to costs and income and are recognized in the period in which they are determined. Provisions for estimated losses on uncompleted contracts are recognized immediately in the period in which such losses are determined. The Company defers precontract costs when such costs are directly associated with specific anticipated contracts and their recovery is probable. The Company recognizes real estate services revenues from property development and management as it satisfies its performance obligations under these service arrangements. The Company assesses whether multiple contracts with a single counterparty may be combined into a single contract for the revenue recognition purposes based on factors such as the timing of the negotiation and execution of the contracts and whether the economic substance of the contracts was contemplated separately or in tandem. 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. The Company 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. The Company capitalizes direct and indirect project costs associated with the initial development 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, 2018 , 2017 , and 2016 was $5.0 million , $1.3 million and $1.0 million , respectively. Overhead, salaries and related personnel costs capitalized during the years ended December 31, 2018 , 2017 , and 2016 were $3.1 million , $2.4 million and $1.7 million , respectively. The Company 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, 2018 and 2017 were $1.2 million and $1.4 million , respectively. Costs attributable to unsuccessful projects are expensed. Income producing property is depreciated on a straight-line basis over the following estimated useful lives: Buildings 39 years Capital improvements 5—20 years Equipment 3—7 years Tenant improvements Term of the related lease (or estimated useful life, if shorter) Operating Property Acquisitions In connection with operating property acquisitions, the Company identifies and recognizes all assets acquired and liabilities assumed at their estimated fair values or relative fair values subsequent to the adoption of the new accounting guidance discussed below, as of the acquisition date. The purchase price allocations to tangible assets, such as land, site improvements, and buildings and improvements are presented within income producing property in the consolidated balance sheets and depreciated over their estimated useful lives. Acquired lease intangibles are presented within other assets and other liabilities in the consolidated balance sheets and amortized over their respective lease terms. 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. Prior to October 1, 2016, the Company expensed all costs incurred related to operating property acquisitions. On October 1, 2016, the Company adopted newly issued accounting guidance that allows capitalization of costs related to operating property acquisitions that do not meet the definition of a business under the new guidance discussed below under "Recent Accounting Pronouncements". The Company values land based on a market approach, looking to recent sales of similar properties, adjusting for differences due to location, the state of entitlement, as well as the shape and size of the parcel. Improvements to land are valued using a replacement cost approach. The approach applies industry standard replacement costs adjusted for geographic specific considerations and reduced by estimated depreciation. The value of buildings acquired is estimated using the replacement cost approach, assuming the buildings were vacant at acquisition. The replacement cost approach considers the composition of the structures acquired, adjusted for an estimate of depreciation. The estimate of depreciation is made considering industry standard information and depreciation curves for the identified asset classes. The value of acquired lease intangibles considers the estimated cost of leasing the properties as if the acquired buildings were vacant, as well as the value of the current leases relative to market-rate leases. The in-place lease value is determined using an estimated total lease-up time and lost rental revenues during such time. The value of current leases relative to market-rate leases is based on market rents obtained for market comparables. Given the significance of unobservable inputs used in the valuation of acquired real estate assets, the Company classifies them as Level 3 inputs in the fair value hierarchy. The Company values debt assumed in connection with operating property acquisitions based on a discounted cash flow analysis of the expected cash flows of the debt. Such analysis considers the contractual terms of the debt, including the period to maturity, credit characteristics, and other terms of the arrangements, which are Level 3 inputs in the fair value hierarchy. Real Estate Sales The Company accounts for the sale of real estate assets and any related gain in accordance with the accounting guidance applicable to sales of real estate, which establishes standards for recognition of profit on all real estate sales transactions other than retail land sales. The Company recognizes the sale and associated gain or loss once it transfers control of the real estate asset and the Company does not have significant continuing involvement. 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. As of December 31, 2018 , the Waynesboro Commons shopping center was classified as held for sale. No properties were held for sale as of December 31, 2017 . Impairment of Long Lived Assets The Company 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, the Company 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. The impairment charges recognized during the year ended December 31, 2018 primarily relate to the $1.5 million impairment of Waynesboro Commons, which was classified as of held for sale as of December 31, 2018 . Impairment charges recognized during the years ended December 31, 2017 and 2016 represent unamortized leasing or acquired intangible assets related to vacated tenants. Interest Income Interest income on notes receivable is accrued based on the contractual terms of the loans and when it is deemed collectible. Many loans provide for accrual of interest that will not be paid until maturity of the loan. Interest is recognized on these loans at the accrual rate subject to the determination that accrued interest is ultimately collectible, based on the underlying collateral and the status of development activities, as applicable. If this determination cannot be made, recognition of interest income may be fully or partially deferred until it is ultimately paid. 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. 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, 2018 and 2017 , accrued straight-line rental revenue presented within accounts receivable in the consolidated balance sheets was $15.2 million and $12.8 million , respectively. The Company’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. The Company establishes reserves for tenant receivables outstanding over 90 days. For all such tenants, the Company also reserves any related accrued straight-line rental revenue. Additional reserves are recorded for more current amounts, as applicable, when the Company has determined collectability to be doubtful. As of December 31, 2018 and 2017 , the allowance for doubtful accounts was $0.6 million and $0.5 million , respectively. The Company presents bad debt expense within rental expenses in the consolidated statements of comprehensive income. Notes Receivable Notes receivable represent financing to third parties in the form of mortgage or mezzanine loans for the development of new real estate. The Company's mezzanine loans are typically made to borrowers who have little or no equity in the underlying development projects. Mezzanine loans are secured, in part, by pledges of ownership interests of the entities that own the underlying real estate. The loans generally have junior liens on the respective real estate projects. The Company evaluates the collectability of both the interest on and principal of each of its notes receivable based primarily upon the financial condition of the individual borrowers. The Company considers factors such as the progress of development activities, including leasing activities, projected development costs, and current and projected loan balances. A loan is determined to be impaired when, based upon then-current information, it is no longer probable that the Company will be able to collect all contractual amounts due from the borrower. The amount of impairment loss recognized is measured as the difference between the carrying amount of the loan and its estimated realizable value. Guarantees The Company measures and records a liability for the fair value of its guarantees on a nonrecurring basis upon issuance using Level 3 internally-developed inputs. These guarantees typically relate to payments that could be required of the Company to senior lenders on its mezzanine loan investments. The Company bases its estimated fair value on the market approach, which compares the guarantee terms and credit characteristics of the underlying development project to other projects for which guarantee pricing terms are available. The offsetting entry for the guarantee liability is a premium on the related loan receivable. The liability is amortized on a straight-line basis over the remaining term of the guarantee. On a quarterly basis, the Company assesses the likelihood of a contingent liability in connection with these guarantees and will record an additional guarantee liability if the unamortized guarantee liability is insufficient. Leasing Costs Commissions paid by the Company 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 the Company 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. 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 as a direct deduction from the carrying value of the associated debt liability in the consolidated balance sheets. Derivative Financial Instruments The Company may enter into interest rate derivatives to manage exposure to interest rate risks. The Company does not use derivative financial instruments for trading or speculative purposes. The Company recognizes derivative financial instruments at fair value and presents them within other assets and liabilities in the consolidated balance sheets. Gains and losses resulting from changes in the fair value of derivatives that are neither designated nor qualify as hedging instruments are recognized within the change in fair value of interest rate derivatives caption in the consolidated statements of comprehensive income. For derivatives that qualify as cash flow hedges, the gain or loss is reported as a component of other comprehensive income (loss) and reclassified into earnings in the periods during which the hedged forecasted transaction affects earnings. 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 statements of comprehensive income. Total stock-based compensation expense recognized during the years ended December 31, 2018 , 2017 , and 2016 was $1.3 million , $1.3 million and $1.1 million , respectively. Stock-based compensation for personnel directly involved in the construction and development of a property is capitalized. During the years ended December 31, 2018 , 2017 , and 2016 , the Company capitalized $0.7 million , $0.4 million , and $0.3 million , respectively, of stock-based compensation. The effect of forfeitures of awards is recorded as they occur. Income Taxes The Company has elected to be taxed as a 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 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 carry back 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. Discontinued Operations 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. Diluted net income per share and unit is calculated after giving effect to all significant potential dilutive shares outstanding during the period. Potential dilutive shares outstanding during the period include nonvested restricted stock awards. However, there were no significant potential dilutive shares or units outstanding for each of the three years ended December 31, 2018 . As a result, basic and diluted outstanding shares and units were the same for all periods presented. See Note 11 for the changes in the Company’s nonvested restricted awards during the year ended December 31, 2018 . Recent Accounting Pronouncements On February 25, 2016, the FASB issued a new lease standard that requires lessees to recognize most leases in their balance sheets as lease liabilities with corresponding right-of-use assets. The new standard also makes targeted changes to lessor accounting. The new standard will be effective for the Company on January 1, 2019 and requires a modified retrospective transition approach for all leases existing at, or entered into after, the beginning of the earliest comparative period presented, with an option to use certain transition relief. Management is currently evaluating the potential impact of the new standard on the Company’s consolidated financial statements. The Company is the lessee on certain long-term ground leases, which represents a majority of the Company's current operating lease payments, and expects to record lease liabilities and corresponding right-of-use assets totaling between $30.0 million and $45.0 million for these leases under the new standard. The Company anticipates utilizing certain transition relief under the new standard that will allow the Company not to reassess the classification of any expired or existing leases, the treatment of initial direct costs relating to these leases, and any lease components of existing service contracts. Additionally, the Company, as lessor, anticipates utilizing a practical expedient allowing the Company to not allocate the consideration in a lease to a separate lease component and a nonlease component (relating to certain common area maintenance activities). On January 5, 2017, the FASB issued new guidance that modifies the definition of a business. Under this new guidance, many real estate acquisitions will now be considered asset acquisitions, allowing costs associated with these acquisitions to be capitalized. The Company adopted this guidance on October 1, 2016, resulting in the capitalization of approximately $0.7 million of acquisition costs related to two acquisitions in the fourth quarter of 2016. If the Company had adopted this guidance on January 1, 2016, approximately $1.4 million in acquisition costs would have been capitalized. On February 22, 2017, the FASB issued new guidance that clarifies the scope and application of guidance on sales or transfers of nonfinancial assets and in substance nonfinancial assets to customers, including partial sales. The new guidance applies to all nonfinancial assets, including real estate, and defines an in substance nonfinancial asset. The Company adopted the new guidance on January 1, 2018, and it did not have a material impact on the Company's consolidated financial statements. On August 28, 2017, the FASB issued new guidance that simplifies some of the requirements relating to accounting for derivatives and hedging. The new guidance

Segment Reporting [Abstract]
Segments	Segments Net operating income (segment revenues minus segment expenses) is the measure used by the Company’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. The Company 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 the Company’s real estate and construction businesses. Net operating income of the Company’s reportable segments for the years ended December 31, 2018 , 2017 , and 2016 was as follows (in thousands): Years Ended December 31, 2018 2017 2016 Office real estate Rental revenues $ 20,701 $ 19,207 $ 20,929 Rental expenses 5,858 5,483 5,560 Real estate taxes 2,034 1,859 2,000 Segment net operating income 12,809 11,865 13,369 Retail real estate Rental revenues 67,959 63,109 56,511 Rental expenses 10,903 10,234 9,116 Real estate taxes 6,801 6,175 5,395 Segment net operating income 50,255 46,700 42,000 Multifamily residential real estate Rental revenues 28,298 26,421 21,915 Rental expenses 10,461 9,705 7,228 Real estate taxes 2,548 2,494 2,234 Segment net operating income 15,289 14,222 12,453 General contracting and real estate services Segment revenues 76,359 194,034 159,030 Segment expenses 73,628 186,590 153,375 Segment gross profit 2,731 7,444 5,655 Net operating income $ 81,084 $ 80,231 $ 73,477 Rental expenses represent costs directly associated with the operation and management of the Company’s real estate properties. Rental expenses include asset management fees, property management fees, repairs and maintenance, insurance, and utilities. General contracting and real estate services revenues for the years ended December 31, 2018 , 2017 , and 2016 exclude revenue related to intercompany construction contracts of $134.4 million , $51.5 million and $43.3 million , respectively, as it is eliminated in consolidation.

The partnership, Market at Mill Creek Partners, LLC, acquired undeveloped land on February 16, 2018 for a contract price of $2.9 million plus capitalized acquisition costs of $0.1 million . The Company is responsible for funding the equity requirements of this development. As of December 31, 2018 , the book value of the Company's investment in the project totaled $21.1 million . Management has concluded that this entity is a VIE as it lacks sufficient equity to fund its operations without additional financial support. The Company is the developer of the shopping center and has the power to direct the activities of the project that most significantly impact its performance and is the party most closely associated with the project. Therefore, the Company is the project's primary beneficiary and consolidates the project in its consolidated financial statements. On April 2, 2018, the Company acquired undeveloped land in Newport News, Virginia for less than $0.1 million . This land parcel is being used in the development of the Brooks Crossing Office property.

The gain on the disposition of the land was less than $0.1 million . Equity Method Investments City Center On February 25, 2016, the Company acquired a 37% interest in Durham City Center II, LLC (“City Center”) for purposes of developing a 22 -story mixed-use tower in Durham, North Carolina. The Company is a minority partner in the joint venture and serves as the project's general contractor, with full ownership of the office and retail portions of the project. During the years ended December 31, 2018 and 2017 , the Company invested $7.3 million and $11.2 million , respectively, in the City Center project. As of December 31, 2018 and 2017 , the Company had invested $21.3 million and $10.9 million , respectively, in City Center, and the carrying value of the Company's investment was $22.2 million and $11.4 million , respectively. The Company has agreed to guarantee the commercial component of the construction loan for City Center; however, the loan is collateralized by 100% of the assets of City Center. As of December 31, 2018 and 2017 , $48.9 million and $29.2 million , respectively, had been drawn against the construction loan, of which $18.5 million and $11.2 million , respectively, was attributable to the Company's portion of the loan. For the year ended December 31, 2018 , City Center had operating income of $0.4 million allocated to the Company. For the years ended December 31, 2017 and 2016 , City Center had no operating activity, and therefore the Company received no allocated income. Based on the terms of City Center’s operating agreement, the Company has concluded that City Center is a VIE, and that the Company holds a variable interest. The Company does not have the power to direct the activities of the project that most significantly impact its performance. Accordingly, the Company is not the project’s primary beneficiary and, therefore, does not consolidate City Center in its consolidated financial statements.

The Company recognized interest income for the years ended December 31, 2018 , 2017 , and 2016 as follows (in thousands): Years Ended December 31, Development Project 2018 2017 2016 1405 Point $ 2,080 $ 1,741 $ 1,204 The Residences at Annapolis Junction 4,939 (a) 4,132 2,018 North Decatur Square 2,212 1,035 — Delray Plaza 928 163 — Nexton Square 235 — — Interlock Commercial 202 — — Solis Apartments at Interlock 55 — — Total mezzanine 10,651 7,071 3,222 Other interest income 78 6 6 Total interest income $ 10,729 $ 7,077 $ 3,228 ________________________________________ (a) Includes amortization of the $5.0 million option purchase fee paid by the borrower in November 2018. As of December 31, 2018 and 2017 , there was no allowance for loan losses. During the years ended December 31, 2018 , 2017 , and 2016 , there was no provision for loan losses recorded for any of the Company's notes receivable. 1405 Point On October 15, 2015, the Company entered into a note receivable with a maximum principal balance of $28.2 million for the 1405 Point project in the Harbor Point area of Baltimore, Maryland (also known as Point Street Apartments). On November 11, 2018, this loan was modified to increase the maximum amount of the loan to $31.0 million . 1405 Point is a 17 -story building comprising 289 residential units and 18,000 square feet of street-level retail space. Beatty Development Group (“BDG”) is the developer of the project and has engaged the Company to serve as construction general contractor. 1405 Point opened during the first quarter of 2018 and is subject to a ground lease from an affiliate of BDG. BDG secured a senior construction loan of up to $67.0 million to fund the development and construction of 1405 Point on November 10, 2016. The Company agreed to guarantee $25.0 million of the senior construction loan in exchange for the option to purchase up to an 88% controlling interest in 1405 Point upon completion of the project as follows: (i) an option to purchase a 79% indirect interest in 1405 Point for $27.6 million , exercisable within one year from the project’s completion (the “First Option”) and (ii) provided that the Company has exercised the First Option, an option to purchase an additional 9% indirect interest in 1405 Point for $3.1 million , exercisable within 27 months from the project’s completion (the “Second Option”). On December 31, 2018, the Second Option was modified to allow the Company to purchase the remaining 21% of the project prior to July 31, 2020 in exchange for increased payments under the ground lease. The Company currently has a $2.1 million letter of credit for the guarantee of the senior construction loan. Interest on the BDG mezzanine loan accrues at 8.0% per annum. The BDG mezzanine loan matures on the earliest of: (i) November 1, 2020, (ii) the maturity date or earlier termination of the senior construction loan, or (iii) the date the Company exercises the First Option as described above. In the event the Company exercises the First Option, BDG is required to pay down the outstanding BDG mezzanine loan in full, with the difference between the BDG loan and $28.2 million applied to the senior construction loan. In the event the Company does not exercise either the First Option or the Second Option, the interest rate on the BDG loan will automatically be reduced to the interest rate on the senior construction loan for the remaining term of the BDG loan. Management has concluded that this entity is a VIE. Because BDG is the developer and operator of 1405 Point, the Company does not have the power to direct the activities of the project that most significantly impact its performance. Therefore, the Company is not the project's primary beneficiary and does not consolidate the project in its consolidated financial statements. The Residences at Annapolis Junction On April 21, 2016, the Company entered into a note receivable with a maximum principal balance of $48.1 million in the Annapolis Junction residential component of the Annapolis Junction Town Center project in Maryland (“Annapolis Junction”). Annapolis Junction is an apartment development project with 416 residential units. It is part of a mixed-use development project that is also planned to have 17,000 square feet of retail space and a 150 -room hotel. Annapolis Junction Apartments Owner, LLC (“AJAO”) is the developer of the residential component and engaged the Company to serve as construction general contractor for the residential component. Annapolis Junction opened during 2017 and 2018 and is currently in lease-up. AJAO secured a senior construction loan of up to $60.0 million to fund the development and construction of Annapolis Junction's residential component on September 30, 2016. The Company agreed to guarantee up to $25.0 million of the senior construction loan in exchange for the option to purchase up to an 88% controlling interest in Annapolis Junction upon completion of the project as follows: (i) an option to purchase an 80% indirect interest in Annapolis Junction's residential component for 91% of the lesser of the seller’s budgeted or actual cost, exercisable within one year from the project’s completion (the “First Option”) and (ii) provided that the Company exercised the First Option, an option to purchase an additional 8% indirect interest in Annapolis Junction for 9% of the lesser of the seller’s actual or budgeted cost, exercisable within 27 months from the project’s completion (the “Second Option”). Interest on the AJAO loan accrues at 10.0% per annum. On November 16, 2018, AJAO refinanced the senior construction loan with a one year senior loan of $83.0 million . This senior loan may be extended for one additional year if certain minimum debt yields and minimum debt service coverage ratios are met by AJAO. The Company has agreed to guarantee $8.3 million of the senior loan, and the AJAO loan will mature concurrent with the new senior loan. In conjunction with this refinancing, the Company sold the First Option and Second Option to AJAO for a price of $5.0 million . Additionally, AJAO repaid $11.1 million of the outstanding mezzanine loan balance, which comprises a $9.9 million payment of accrued interest and a $1.2 million payment of principal. The Option sale proceeds of $5.0 million is being accounted for as a loan discount that will be recognized as interest income over the one year term of the loan using the effective interest method. Management has concluded that this entity is a VIE. Because AJAO is the developer of Annapolis Junction, the Company does not have the power to direct the activities of the project that most significantly impact its performance. Therefore, the Company is not the project's primary beneficiary and does not consolidate the project in its consolidated financial statements. North Decatur Square On May 15, 2017, the Company invested in the development of an estimated $34.0 million Whole Foods-anchored center located in Decatur, Georgia. The Company's investment is in the form of a mezzanine loan of up to $21.8 million to the developer, North Decatur Square Holdings, LLC ("NDSH"). Interest on the loan bears interest at a rate of 15.0% per annum. The note matures on the earliest of (i) May 15, 2022, (ii) the maturity of the senior construction loan, (iii) the sale of NDSH, or (iv) the sale of the center. NDSH is current on this loan. During 2018, this loan was modified to increase the maximum amount of the loan to $29.7 million due to an increase in the square footage of the Whole Foods store. Management has concluded that this entity is a VIE. Because NDSH is the developer of North Decatur Square, the Company does not have the power to direct the activities of the project that most significantly impact its performance. Therefore, the Company is not the project's primary beneficiary and does not consolidate the project in its consolidated financial statements. Delray Plaza On October 27, 2017, the Company invested in the development of an estimated $20.0 million Whole Foods-anchored center located in Delray Beach, Florida. The Company's investment was in the form of a mezzanine loan of up to $13.1 million to the developer, Delray Plaza Holdings, LLC ("DPH"). The Company has agreed to guarantee payment of up to $4.8 million of the senior construction loan. On January 8, 2019, this loan was modified to increase the maximum amount of the loan to $15.0 million and the payment guarantee amount increased to $5.2 million . The mezzanine loan bears interest at a rate of 15.0% per annum. The note matures on the earliest of (i) October 27, 2020, (ii) the date of any sale or refinance of the development project, or (iii) the disposition or change in control of the development project. Management has concluded that this entity is a VIE. Because DPH is the developer of Delray Plaza, the Company does not have the power to direct the activities of the project that most significantly impact its performance. Therefore, the Company is not the project's primary beneficiary and does not consolidate the project in its consolidated financial statements. Nexton Square On August 31, 2018, the Company financed a $2.2 million bridge loan to SC Summerville Brighton, LLC ("Brighton"), the developer of Nexton Square, a shopping center development project located in Summerville, South Carolina. The shopping center may comprise as many as 16 buildings. On November 7, 2018, the Company increased the maximum loan amount to $4.9 million . This loan was subsequently modified as described below. On December 4, 2018, the Company entered into a mezzanine loan agreement with Brighton, which provides for a maximum capacity of $21.0 million . The previous loan was repaid from proceeds of the mezzanine loan. This note bears interest at a rate of 15.0% per annum (which will decrease to 10.0% upon completion of certain portions of the project). The modified note matures on the earliest of (i) December 4, 2020, (ii) the maturity date of the senior construction loan, including any extension options available and exercised under that loan, or (iii) the date of any sale, transfer, or refinancing of the project. The Company agreed to guarantee 50% of the senior construction loan in exchange for the option to purchase the property upon completion according to a predetermined formula, which is primarily dependent upon Brighton's leasing activities and the extent to which Brighton elects to complete all or a portion of the total planned space, if applicable, in response to leasing activities. On February 8, 2019, Brighton closed on a senior construction loan with a maximum borrowing capacity of $25.2 million . Brighton used proceeds from its original draw in part to repay $2.1 million of the mezzanine loan. Management has concluded that this entity is a VIE. Because Brighton is the developer of Nexton Square, the Company does not have the power to direct the activities of the project that most significantly impact its performance. Therefore, the Company is not the project's primary beneficiary and does not consolidate the project in its consolidated financial statements. Interlock Commercial In October 2018, the Company financed a bridge loan with a maximum commitment of $4.0 million to The Interlock, LLC ("Interlock"), the developer of the office and retail components of The Interlock, a new mixed-use public-private partnership with Georgia Tech in West Midtown Atlanta. This loan was subsequently modified as described below. On December 21, 2018, the Company entered into a mezzanine loan agreement with Interlock for a maximum principal amount of $67.0 million and a total maximum commitment, including accrued interest reserves, of $95.0 million . The previous loan was repaid from proceeds of the mezzanine loan. The mezzanine loan bears interest at a rate of 15.0% per annum and matures at the earlier of (i) 24 months after the original maturity date or earlier termination date of the senior construction loan or (ii) any sale, transfer, or refinancing of the project. In the event that the maturity date is established as being 24 months after the original maturity date or earlier termination date of the senior construction loan, Interlock will have the right to extend the maturity date for 5 years . The Company has agreed to guarantee payment of 35% of the senior construction loan. Interlock had not yet obtained a senior construction loan as of December 31, 2018 . See Note 18 for additional discussion. Management has concluded that this entity is a VIE. Because Interlock is the developer of The Interlock, the Company does not have the power to direct the activities of the project that most significantly impact its performance. Therefore, the Company is not the project's primary beneficiary and does not consolidate the project in its consolidated financial statements. Solis Apartments at Interlock On December 21, 2018, the Company entered into a mezzanine loan agreement with Interlock Mezz Borrower, LLC ("Solis Interlock"), the developer of Solis Apartments at Interlock, which is the apartment component of The Interlock. The mezzanine loan has a maximum principal commitment of $25.2 million and a total maximum commitment, including accrued interest reserves, of $41.1 million . The mezzanine loan bears interest at a rate of 13.0% per annum and matures on the earlier of (a) the later of (i) December 21, 2021 or (ii) the maturity date or earlier termination date of the senior construction loan, including any extensions of the senior construction loan, or (b) the date of any sale of the project or refinance of the loan. Management has concluded that this entity is a VIE. Because Solis Interlock is the developer of Solis Apartments at Interlock, the Company does not have the power to direct the activities of the project that most significantly impact its performance. Therefore, the Company is not the project's primary beneficiary and does not consolidate the project in its consolidated financial statements. Guarantee liabilities As of December 31, 2018 , the Company had outstanding payment guarantees for the senior loans on Residences at Annapolis Junction, Delray Plaza, and 1405 Point, as described above. As of December 31, 2018 , the Company has recorded a guarantee liability of $2.8 million , representing their unamortized fair value. These guarantees are classified as other liabilities on the Company's consolidated balance sheets, with a corresponding adjustment to the notes receivable balance on the consolidated balance sheets. See Note 18 for additional information on the Company's outstanding guarantees.

Such amounts become billable according to contract terms, which usually consider the passage of time, achievement of certain milestones, or completion of the project. The Company expects to bill and collect substantially all construction contract costs and estimated earnings in excess of billings as of December 31, 2018 during the year ending December 31, 2019. Billings in excess of construction contract costs and estimated earnings represent billings or collections on contracts made in advance of revenue recognized. The following table summarizes the changes to the balances in the Company’s construction contract costs and estimated earnings in excess of billings account and the billings in excess of construction contract costs and estimated earnings account for the year ended December 31, 2018 (in thousands): Construction contract costs and estimated earnings in excess of billings Billings in excess of construction contract costs and estimated earnings Balance as of January 1, 2018 $ 245 $ 3,591 Revenue recognized that was included in the balance at the beginning of the period — (3,591 ) Increases due to new billings, excluding amounts recognized as revenue during the period — 4,243 Transferred to receivables (245 ) — Construction contract costs and estimated earnings not billed during the period 352 — Changes due to cumulative catch-up adjustment arising from changes in the estimate of the stage of completion 1,006 (1,206 ) Balance as of December 31, 2018 $ 1,358 $ 3,037 The Company defers pre-contract costs when such costs are directly associated with specific anticipated contracts and their recovery is probable. Pre-contract costs of $1.4 million and $0.6 million were deferred as of December 31, 2018 and 2017 , respectively. Amortization of pre-contract costs for the year ended December 31, 2018 totaled less than $0.1 million . Construction receivables and payables include retentions—amounts that are generally withheld until the completion of the contract or the satisfaction of certain restrictive conditions such as fulfillment guarantees. As of December 31, 2018 and 2017 , construction receivables included retentions of $8.5 million and $9.9 million , respectively.

Credit Facility On October 26, 2017, the Operating Partnership entered into an amended and restated credit agreement (the “credit agreement”), which provides for a $300.0 million credit facility comprised of a $150.0 million senior unsecured revolving credit facility (the "revolving credit facility") and a $150.0 million senior unsecured term loan facility (the “term loan facility” and, together with the revolving credit facility, the “credit facility”), with a syndicate of banks. The amended credit facility replaces the prior $150.0 million revolving credit facility, which was scheduled to mature on February 20, 2019, and the prior $125.0 million term loan facility, which was scheduled to mature on February 20, 2021. The credit facility includes an accordion feature that allows the total commitments to be increased to $450.0 million , subject to certain conditions, including obtaining commitments from any one or more lenders. The revolving credit facility has a scheduled maturity date of October 26, 2021, with two six -month extension options, subject to certain conditions, including payment of a 0.075% extension fee at each extension. The term loan facility has a scheduled maturity date of October 26, 2022.

The Company may, at any time, voluntarily prepay any loan under the credit facility in whole or in part without premium or penalty. The Operating Partnership is the borrower under the credit facility, and its obligations under the credit facility are guaranteed by the Company and certain of its subsidiaries that are not otherwise prohibited from providing such guaranty. The credit agreement contains customary representations and warranties and financial and other affirmative and negative covenants. The Company's ability to borrow under the credit facility is subject to ongoing compliance with a number of financial covenants, affirmative covenants, and other restrictions. The credit agreement includes customary events of default, in certain cases subject to customary cure periods. The occurrence of an event of default, if not cured within the applicable cure period, would permit the lenders to, among other things, declare the unpaid principal, accrued and unpaid interest, and all other amounts payable under the credit facility to be immediately due and payable. The Company is currently in compliance with all covenants under the credit facility. Other 2018 Financing Activity On January 22, 2018, the Company extended and modified the Sandbridge Commons note.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	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 values. Financial assets and liabilities whose fair values are measured on a recurring basis using Level 2 inputs consist of interest rate swaps and 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. Financial assets and liabilities whose fair values are not measured at fair value but for which the fair value is disclosed include the Company's notes receivable and indebtedness. The fair value is estimated by discounting the future cash flows of each instrument at estimated market rates consistent with the maturity, credit characteristics, and other terms of the arrangements, which are Level 3 inputs under the fair value hierarchy. 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. Considerable judgment is used to estimate the fair value of financial instruments. The estimates of fair value presented herein are not necessarily indicative of the amounts that could be realized upon disposition of the financial instruments. The carrying amounts and fair values of the Company’s financial instruments as of December 31, 2018 and 2017 were as follows (in thousands): December 31, 2018 2017 Carrying Value Fair Value Carrying Value Fair Value Indebtedness, net $ 694,239 $ 688,437 $ 517,272 $ 518,417 Notes receivable 138,683 138,683 83,058 83,058 Interest rate swap liabilities 2,474 2,474 69 69 Interest rate swap and cap assets 2,093 2,093 1,525 1,525

The Tax Act reduced the U.S. federal corporate tax rate from 35% to 21% (including with respect to taxable REIT subsidiaries), resulting in the Company's remeasuring its existing deferred tax balances. In addition, generally beginning in 2018, the Tax Act alters the deductibility of certain items (e.g., interest expense) and allows the cost of certain qualifying capital asset investments to be deducted fully in the year they were purchased, subject to a phase-down of the deduction percentage over time. The provisional amounts recorded in the year ended December 31, 2017 related to the remeasurement of the deferred tax balance was approximately $0.2 million of tax expense. The Company's accounting for the income tax effects of the Tax Act has been completed, and no further changes to the accounting were made. As of December 31, 2018 and 2017 , the Company had $0.4 million and $0.3 million , respectively, of net deferred tax assets representing basis differences in the assets of the TRS and stock-based compensation attributable to the TRS.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies 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.

Significant Accounting Polici_2

Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2018
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying consolidated 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, its wholly owned subsidiaries, and any interests in variable interest entities ("VIEs") where the Company has been determined to be the primary beneficiary. All significant intercompany transactions and balances have been eliminated in consolidation.
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 the Company’s properties individually and aggregates such properties into segments based on their economic characteristics and classes of tenants. The Company 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. The Company’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.
Reclassifications	Reclassifications Certain amounts previously reported in the consolidated financial statements have been reclassified in the accompanying consolidated financial statements to conform to the current period's presentation.
Revenue Recognition	Revenue Recognition Rental Revenues The Company leases its properties under operating leases and recognizes base rents when earned on a straight-line basis over the lease term. Rental revenues include $2.7 million , $1.2 million and $1.1 million of straight-line rent adjustments for the years ended December 31, 2018 , 2017 , and 2016 , respectively. The Company 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 the Company’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 probable. The Company recognizes contingent rental revenue (e.g., percentage rents based on tenant sales thresholds) when the sales thresholds are met. Contingent rents included in rental revenues were $0.3 million , $0.4 million , and $0.4 million for the years ended December 31, 2018 , 2017 , and 2016 , respectively. The Company recognizes leasing incentives as reductions to rental revenue on a straight-line basis over the lease term. Leasing incentive amortization was $0.7 million , $0.8 million , and $0.8 million for the years ended December 31, 2018 , 2017 , and 2016 , respectively. The Company recognizes fair value adjustments recorded at the time of lease assumption in rental income on a straight line basis as a reduction to revenue over the remaining life of the lease or any renewal periods for which the Company determines have value at the time of acquisition. The Company 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. The Company recognizes lease termination fees either upon termination or amortizes them over any remaining lease term. General Contracting and Real Estate Services Revenues On May 28, 2014, the Financial Accounting Standards Board ("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 changes the way the Company recognizes revenue from construction and development contracts with third party customers. The Company adopted this standard on January 1, 2018 using the modified retrospective method, applying this standard to all contracts not yet completed as of that date. In applying the standard to the Company’s future construction contracts, certain pre-contract costs incurred by the Company are now deferred and amortized over the period during which construction obligations are fulfilled. Previously, these costs were immediately recorded as general contracting expenses upon commencement of construction, with the corresponding general contracting revenue also recorded. Applying the standard to the Company’s uncompleted contracts as of January 1, 2018 did not result in material differences to these contracts in aggregate, and no cumulative adjustment to distributions in excess of earnings was recorded as of January 1, 2018. The Company recognizes general contracting revenues as a customer obtains control of promised goods or services in an amount that reflects the consideration the Company expects to receive in exchange for those goods or services. For each construction contract, the Company identifies the performance obligations, which typically include the delivery of a single building constructed according to the specifications of the contract. The Company estimates the total transaction price, which generally includes a fixed contract price and may also include variable components such as early completion bonuses, liquidated damages, or cost savings to be shared with the customer. Variable components of the contract price are included in the transaction price to the extent that it is probable that a significant reversal of revenue will not occur. The Company recognizes the estimated transaction price as revenue as it satisfies its performance obligations; the Company estimates its progress in satisfying performance obligations for each contract using the input method, based on the proportion of incurred costs relative to total estimated construction costs at completion. Construction contract costs include all direct material, direct labor, subcontract costs, and overhead costs directly related to contract performance. Changes in job performance, job conditions, and estimated profitability, including those arising from contract penalty provisions and final contract settlements, are all significant judgments that may result in revisions to costs and income and are recognized in the period in which they are determined. Provisions for estimated losses on uncompleted contracts are recognized immediately in the period in which such losses are determined. The Company defers precontract costs when such costs are directly associated with specific anticipated contracts and their recovery is probable. The Company recognizes real estate services revenues from property development and management as it satisfies its performance obligations under these service arrangements. The Company assesses whether multiple contracts with a single counterparty may be combined into a single contract for the revenue recognition purposes based on factors such as the timing of the negotiation and execution of the contracts and whether the economic substance of the contracts was contemplated separately or in tandem.
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. The Company 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. The Company capitalizes direct and indirect project costs associated with the initial development 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, 2018 , 2017 , and 2016 was $5.0 million , $1.3 million and $1.0 million , respectively. Overhead, salaries and related personnel costs capitalized during the years ended December 31, 2018 , 2017 , and 2016 were $3.1 million , $2.4 million and $1.7 million , respectively. The Company 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, 2018 and 2017 were $1.2 million and $1.4 million , respectively. Costs attributable to unsuccessful projects are expensed. Income producing property is depreciated on a straight-line basis over the following estimated useful lives: Buildings 39 years Capital improvements 5—20 years Equipment 3—7 years Tenant improvements Term of the related lease (or estimated useful life, if shorter)
Operating Property Acquisitions	Operating Property Acquisitions In connection with operating property acquisitions, the Company identifies and recognizes all assets acquired and liabilities assumed at their estimated fair values or relative fair values subsequent to the adoption of the new accounting guidance discussed below, as of the acquisition date. The purchase price allocations to tangible assets, such as land, site improvements, and buildings and improvements are presented within income producing property in the consolidated balance sheets and depreciated over their estimated useful lives. Acquired lease intangibles are presented within other assets and other liabilities in the consolidated balance sheets and amortized over their respective lease terms. 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. Prior to October 1, 2016, the Company expensed all costs incurred related to operating property acquisitions. On October 1, 2016, the Company adopted newly issued accounting guidance that allows capitalization of costs related to operating property acquisitions that do not meet the definition of a business under the new guidance discussed below under "Recent Accounting Pronouncements". The Company values land based on a market approach, looking to recent sales of similar properties, adjusting for differences due to location, the state of entitlement, as well as the shape and size of the parcel. Improvements to land are valued using a replacement cost approach. The approach applies industry standard replacement costs adjusted for geographic specific considerations and reduced by estimated depreciation. The value of buildings acquired is estimated using the replacement cost approach, assuming the buildings were vacant at acquisition. The replacement cost approach considers the composition of the structures acquired, adjusted for an estimate of depreciation. The estimate of depreciation is made considering industry standard information and depreciation curves for the identified asset classes. The value of acquired lease intangibles considers the estimated cost of leasing the properties as if the acquired buildings were vacant, as well as the value of the current leases relative to market-rate leases. The in-place lease value is determined using an estimated total lease-up time and lost rental revenues during such time. The value of current leases relative to market-rate leases is based on market rents obtained for market comparables. Given the significance of unobservable inputs used in the valuation of acquired real estate assets, the Company classifies them as Level 3 inputs in the fair value hierarchy. The Company values debt assumed in connection with operating property acquisitions based on a discounted cash flow analysis of the expected cash flows of the debt. Such analysis considers the contractual terms of the debt, including the period to maturity, credit characteristics, and other terms of the arrangements, which are Level 3 inputs in the fair value hierarchy.
Real Estate Sales and Real Estate Investments Held for Sale	Real Estate Sales The Company accounts for the sale of real estate assets and any related gain in accordance with the accounting guidance applicable to sales of real estate, which establishes standards for recognition of profit on all real estate sales transactions other than retail land sales. The Company recognizes the sale and associated gain or loss once it transfers control of the real estate asset and the Company does not have significant continuing involvement. 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.
Impairment of Long Lived Assets	Impairment of Long Lived Assets The Company 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, the Company 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. The impairment charges recognized during the year ended December 31, 2018 primarily relate to the $1.5 million impairment of Waynesboro Commons, which was classified as of held for sale as of December 31, 2018 . Impairment charges recognized during the years ended December 31, 2017 and 2016 represent unamortized leasing or acquired intangible assets related to vacated tenants.
Interest Income	Interest Income Interest income on notes receivable is accrued based on the contractual terms of the loans and when it is deemed collectible. Many loans provide for accrual of interest that will not be paid until maturity of the loan. Interest is recognized on these loans at the accrual rate subject to the determination that accrued interest is ultimately collectible, based on the underlying collateral and the status of development activities, as applicable. If this determination cannot be made, recognition of interest income may be fully or partially deferred until it is ultimately paid.
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.
Accounts Receivable, net	The Company’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. The Company establishes reserves for tenant receivables outstanding over 90 days. For all such tenants, the Company also reserves any related accrued straight-line rental revenue. Additional reserves are recorded for more current amounts, as applicable, when the Company has determined collectability to be doubtful. 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.
Notes Receivable	Notes Receivable Notes receivable represent financing to third parties in the form of mortgage or mezzanine loans for the development of new real estate. The Company's mezzanine loans are typically made to borrowers who have little or no equity in the underlying development projects. Mezzanine loans are secured, in part, by pledges of ownership interests of the entities that own the underlying real estate. The loans generally have junior liens on the respective real estate projects. The Company evaluates the collectability of both the interest on and principal of each of its notes receivable based primarily upon the financial condition of the individual borrowers. The Company considers factors such as the progress of development activities, including leasing activities, projected development costs, and current and projected loan balances. A loan is determined to be impaired when, based upon then-current information, it is no longer probable that the Company will be able to collect all contractual amounts due from the borrower. The amount of impairment loss recognized is measured as the difference between the carrying amount of the loan and its estimated realizable value.
Guarantees	Guarantees The Company measures and records a liability for the fair value of its guarantees on a nonrecurring basis upon issuance using Level 3 internally-developed inputs. These guarantees typically relate to payments that could be required of the Company to senior lenders on its mezzanine loan investments. The Company bases its estimated fair value on the market approach, which compares the guarantee terms and credit characteristics of the underlying development project to other projects for which guarantee pricing terms are available. The offsetting entry for the guarantee liability is a premium on the related loan receivable. The liability is amortized on a straight-line basis over the remaining term of the guarantee. On a quarterly basis, the Company assesses the likelihood of a contingent liability in connection with these guarantees and will record an additional guarantee liability if the unamortized guarantee liability is insufficient.
Leasing Costs	Leasing Costs Commissions paid by the Company 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 the Company 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.
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 as a direct deduction from the carrying value of the associated debt liability in the consolidated balance sheets.
Derivative Financial Instruments	Derivative Financial Instruments The Company may enter into interest rate derivatives to manage exposure to interest rate risks. The Company does not use derivative financial instruments for trading or speculative purposes. The Company recognizes derivative financial instruments at fair value and presents them within other assets and liabilities in the consolidated balance sheets. Gains and losses resulting from changes in the fair value of derivatives that are neither designated nor qualify as hedging instruments are recognized within the change in fair value of interest rate derivatives caption in the consolidated statements of comprehensive income. For derivatives that qualify as cash flow hedges, the gain or loss is reported as a component of other comprehensive income (loss) and reclassified into earnings in the periods during which the hedged forecasted transaction affects earnings.
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 statements of comprehensive income.
Income Taxes	Income Taxes The Company has elected to be taxed as a 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 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 carry back 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.
Discontinued Operations	Discontinued Operations 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. Diluted net income per share and unit is calculated after giving effect to all significant potential dilutive shares outstanding during the period. Potential dilutive shares outstanding during the period include nonvested restricted stock awards.
Recent Accounting Pronouncements	Recent Accounting Pronouncements On February 25, 2016, the FASB issued a new lease standard that requires lessees to recognize most leases in their balance sheets as lease liabilities with corresponding right-of-use assets. The new standard also makes targeted changes to lessor accounting. The new standard will be effective for the Company on January 1, 2019 and requires a modified retrospective transition approach for all leases existing at, or entered into after, the beginning of the earliest comparative period presented, with an option to use certain transition relief. Management is currently evaluating the potential impact of the new standard on the Company’s consolidated financial statements. The Company is the lessee on certain long-term ground leases, which represents a majority of the Company's current operating lease payments, and expects to record lease liabilities and corresponding right-of-use assets totaling between $30.0 million and $45.0 million for these leases under the new standard. The Company anticipates utilizing certain transition relief under the new standard that will allow the Company not to reassess the classification of any expired or existing leases, the treatment of initial direct costs relating to these leases, and any lease components of existing service contracts. Additionally, the Company, as lessor, anticipates utilizing a practical expedient allowing the Company to not allocate the consideration in a lease to a separate lease component and a nonlease component (relating to certain common area maintenance activities). On January 5, 2017, the FASB issued new guidance that modifies the definition of a business. Under this new guidance, many real estate acquisitions will now be considered asset acquisitions, allowing costs associated with these acquisitions to be capitalized. The Company adopted this guidance on October 1, 2016, resulting in the capitalization of approximately $0.7 million of acquisition costs related to two acquisitions in the fourth quarter of 2016. If the Company had adopted this guidance on January 1, 2016, approximately $1.4 million in acquisition costs would have been capitalized. On February 22, 2017, the FASB issued new guidance that clarifies the scope and application of guidance on sales or transfers of nonfinancial assets and in substance nonfinancial assets to customers, including partial sales. The new guidance applies to all nonfinancial assets, including real estate, and defines an in substance nonfinancial asset. The Company adopted the new guidance on January 1, 2018, and it did not have a material impact on the Company's consolidated financial statements. On August 28, 2017, the FASB issued new guidance that simplifies some of the requirements relating to accounting for derivatives and hedging. The new guidance eliminates the requirement to separately measure and report hedge ineffectiveness for a highly effective hedge and also simplifies certain documentation and assessment requirements relating to the determination of hedge effectiveness. The Company adopted this guidance effective July 1, 2018. The application of this guidance to hedging relationships generally eliminates the gains and losses that would otherwise be recorded for these derivative instruments.
Fair Value of Financial Instruments	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 values. Financial assets and liabilities whose fair values are measured on a recurring basis using Level 2 inputs consist of interest rate swaps and 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. Financial assets and liabilities whose fair values are not measured at fair value but for which the fair value is disclosed include the Company's notes receivable and indebtedness. The fair value is estimated by discounting the future cash flows of each instrument at estimated market rates consistent with the maturity, credit characteristics, and other terms of the arrangements, which are Level 3 inputs under the fair value hierarchy. 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. Considerable judgment is used to estimate the fair value of financial instruments. The estimates of fair value presented herein are not necessarily indicative of the amounts that could be realized upon disposition of the financial instruments.
Legal Proceedings	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.
