Accounting Policies [Abstract]
Organization	1. ORGANIZATION
	Comstock Holding Companies, Inc. is a multi-faceted real estate development and construction services company focused on the Washington, D.C. metropolitan area (Washington D.C., Northern Virginia and Maryland suburbs of Washington D.C.). The Company has substantial experience with building a diverse range of products including multi-family units, single-family homes, townhouses, mid-rise condominiums, high-rise multi-family condominiums and mixed-use (residential and commercial) developments. References in this Annual Report on Form 10-K to “Comstock,” “Company,” “we,” “our” and “us” refer to Comstock Holding Companies, Inc. together in each case with our subsidiaries and any predecessor entities unless the context suggests otherwise. Our business was founded in 1985 as a residential land developer and home builder focused on the Northern Virginia suburbs of the Washington, D.C metro market.
	Comstock Companies, Inc. was incorporated on May 24, 2004 as a Delaware corporation. On June 30, 2004, the Company changed its name to Comstock Homebuilding Companies, Inc. On December 17, 2004, the Company completed an initial public offering of its Class A common stock. On June 22, 2012, the Company changed its name to Comstock Holding Companies, Inc. which better reflects the Company’s multi-faceted strategy and capabilities.
	The Company’s Class A common stock is traded on the Nasdaq Capital Market (“NASDAQ”) under the symbol “CHCI” and has no public trading history prior to December 17, 2004.
	Liquidity Developments
	We require capital to operate, to post deposits on new deals, to purchase and develop land, to construct homes, to fund related carrying costs and overhead and to fund various advertising and marketing programs to generate sales. These expenditures include payroll, community engineering, entitlement, architecture, advertising, utilities and interest as well as the construction costs of our homes. Our sources of capital include, and should continue to include, private equity and debt placements (which has included significant participation from Company insiders), funds derived from various secured and unsecured borrowings to finance acquisition, development and construction on acquired land, cash flow from operations, which includes the sale and delivery of constructed homes, finished and raw building lots and the potential sale of public debt and equity securities. The Company is involved in ongoing discussions with lenders and equity sources in an effort to provide additional growth capital to fund various new business opportunities. See Note 8 for more details on our credit facilities and Note 3 for details on private placement offerings in 2014.
	As of December 31, 2014, the Company has $28.7 million of its credit facilities and project related loans that mature during 2015. We are in active discussions with our lenders with respect to these maturities and are seeking extensions and modifications to the loans as necessary. The current performance of the projects and our early discussions with our lenders indicates that we will likely be successful in extending or modifying these loans, though no assurances can be made that we will be successful in these efforts. We are anticipating that successful resolution of those discussions with our lenders, the recently completed capital raises from the aforementioned private placements, current available cash on hand and additional cash from settlement proceeds at existing and under development communities, the Company should have sufficient financial resources to sustain its operations through the next 12 months, though no assurances can be made that the Company will be successful in its efforts.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	A summary of the significant accounting policies and practices used in the preparation of the consolidated financial statements is as follows:
	Basis of presentation
	The accompanying consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) and include the accounts of the Company and all of its majority-owned and controlled subsidiaries. All significant intercompany accounts and transactions have been eliminated. Investments in 50% or less owned partnerships and affiliates are accounted for using the equity method unless it is determined that the Company has control of the entity, in which case the entity would be consolidated. The Company had one joint venture investment accounted for using the equity method as of December 31, 2014 and 2013.
	Cash and cash equivalents and restricted cash
	Cash and cash equivalents are comprised of cash and short-term investments with maturities of three months or less when purchased. At times, the Company may have deposits with institutions in excess of federally insured limits. We monitor the cash balances in our bank accounts and adjust the balance as appropriate. To date, we have experienced no loss or lack of access to our invested cash or cash equivalents; however, we can provide no assurance that access to our cash and cash equivalents will not be impacted by adverse conditions in the financial market. At December 31, 2014 and 2013, the Company had restricted cash of $1.8 million and $2.5 million, respectively, which includes $1.0 million and $2.0 million in deposits, respectively, with an insurance provider as security for future claims.
	Real estate inventories
	Real estate inventories include land, land development costs, construction and other costs. Real estate held for development and use is stated at cost, or when circumstances or events indicate that the real estate is impaired, at estimated fair value. Real estate held for sale is carried at the lower of cost or fair value less estimated costs to sell. Land, land development and indirect land development costs are accumulated by specific project and allocated to various units within that project using specific identification and allocation based upon the relative sales value, unit or area methods. Direct construction costs are assigned to units based on specific identification. Construction costs primarily include direct construction costs and capitalized field overhead. Other costs are comprised of fees, capitalized interest and real estate taxes. Costs incurred to sell real estate are capitalized to the extent they are reasonably expected to be recovered from the sale of the project and are tangible assets or services performed to obtain regulatory approval of sales. Other selling costs are expensed as incurred.
	If the project is considered held for sale, it is valued at the lower of cost or fair value less estimated selling costs. The evaluation takes into consideration the current status of the property, carrying costs, costs of disposition, various restrictions and any other circumstances that may affect fair value including management’s plans for the property. For assets held for development and use, a write-down to estimated fair value is recorded when the net carrying value of the property exceeds its estimated undiscounted future cash flows. Estimated fair value is based on comparable sales of real estate in the normal course of business under existing and anticipated market conditions. These evaluations are made on a property-by-property basis whenever events or changes in circumstances indicate that the net book value may not be recoverable.
	Capitalized interest and real estate taxes
	Interest and real estate taxes incurred relating to the development of lots and parcels are capitalized to real estate inventories during the active development period, which generally commences when borrowings are used to acquire real estate assets and ends when the properties are substantially complete or the property becomes inactive. A project becomes inactive when development and construction activities have been suspended indefinitely. Interest is capitalized based on the interest rate applicable to specific borrowings or the weighted average of the rates applicable to other borrowings during the period. Interest and real estate taxes capitalized to real estate inventories are expensed as a component of cost of sales as related units are sold. The following table is a summary of interest and real estate taxes incurred, capitalized and expensed for units settled:
		Twelve Months Ended December 31
		2014			2013
	Total interest incurred and capitalized	$	2,557		$	1,884
	Total real estate taxes incurred and capitalized		234			181
	Total interest and real estate taxes incurred and capitalized	$	2,791		$	2,065
	Interest expensed as a component of cost of sales	$	557		$	2,146
	Real estate taxes expensed as a component of cost of sales		175			311
	Interest and real estate taxes expensed as a component of cost of sales	$	732		$	2,457
	When a project becomes inactive, its interest, real estate taxes and indirect production overhead costs are no longer capitalized but rather expensed in the period in which they are incurred. Following is a breakdown of the interest, real estate taxes and indirect costs expensed related to inactive projects reported in real estate inventories:
		Twelve Months Ended December 31,
		2014			2013
	Total interest incurred and expensed for inactive projects	$	—		$	73
	Total real estate taxes incurred and expensed for inactive projects		26			49
	Total production overhead incurred and expensed for inactive projects		—			286
		$	26		$	408
	Property, plant and equipment
	Property, plant and equipment are carried at cost less accumulated depreciation and are depreciated on the straight-line method over their estimated useful lives as follows:
	Furniture and fixtures		7 years
	Office equipment		5 years
	Computer equipment and capitalized software		3 years
	Leasehold improvements		Life of related lease
	When assets are retired or otherwise disposed of, the cost and accumulated depreciation are removed from their separate accounts and any gain or loss on sale is reflected in operations. Expenditures for maintenance and repairs are charged to expense as incurred.
	Warranty reserve
	Warranty reserves for units settled are established to cover potential costs for materials and labor with regard to warranty-type claims expected to arise during the typical one-year warranty period provided by the Company or within the two-year statutorily mandated structural warranty period for condominiums. Because the Company typically subcontracts its homebuilding work, subcontractors are required to provide the Company with an indemnity and a certificate of insurance prior to receiving payments for their work. Claims relating to workmanship and materials are generally the primary responsibility of the subcontractors and product manufacturers. The warranty reserve is established at the time of closing, and is calculated based upon historical warranty cost experience and current business factors. This reserve is an estimate and actual warranty costs could vary from these estimates. Variables used in the calculation of the reserve, as well as the adequacy of the reserve based on the number of homes still under warranty, are reviewed on a periodic basis. Warranty claims are directly charged to the reserve as they arise.
	During 2008, the Company recorded an additional $241 in warranty reserves to cover costs and claims related to a project in North Carolina. In August 2014, the Company settled the claim for $59, including legal costs, releasing the Company from future claims and costs related to this project and accordingly reduced the warranty reserve by $182. The warranty release was recorded as a reduction to homebuilding cost of sales in the third quarter of 2014.
	In the third quarter of 2013, the Company settled a legal claim related to one of its projects in Virginia for $0.2 million, releasing the Company from future warranty claims related to this project and accordingly reduced the warranty reserve by $0.4 million. The warranty release was recorded as a reduction to homebuilding cost of sales in the third quarter of 2013.
	The following table is a summary of warranty reserve activity which is included in accounts payable and accrued liabilities:
		Years ended
		December 31,
		2014			2013
	Balance at beginning of period	$	510		$	963
	Additions		454			262
	Releases and/or charges incurred		(472	)		(715	)
	Balance at end of period	$	492		$	510
	Revenue recognition
	The Company recognizes revenues and related profits or losses from the sale of residential properties and units, finished lots and land sales when closing has occurred, full payment has been received, title and possession of the property has transferred to the buyer and the Company has no significant continuing involvement in the property. Other revenues include revenue from land sales, rental revenue from leased multi-family units – which is recognized ratably over the terms of the respective leases, revenue from construction services – which is recognized under the percentage-of-completion method, and revenue earned from management and administrative support services provided to related parties – which is recognized as the services are provided.
	Advertising costs
	The total amount of advertising costs charged for the year ended December 31, 2014 was $743, of which $730 was charged to sales and marketing and $13 was charged to general and administrative expenses. The total amount of advertising costs charged for the year ended December 31, 2013 was $614, of which $577 was charged to sales and marketing, $32 was charged to cost of sales and $5 was charged to general and administrative expenses.
	Stock compensation
	As discussed in Note 12, the Company sponsors stock option plans and restricted stock award plans. The Company accounts for its share-based awards pursuant to Accounting Standards Codification (“ASC”) 718, Share Based Payments. ASC 718 requires all share-based payments to employees, including grants of employee stock options, to be recognized in the financial statements over the vesting period based on their fair values at the date of grant. For the year ended December 31, 2014 and 2013, total stock-based compensation cost was $319 and $616, respectively. Of this amount, $271 and $477 was charged to ‘general and administrative’ expenses for the years ended December 31, 2014 and 2013, respectively, and $24 and $6 was charged to ‘cost of sales-other’ for the years ended December 31, 2014 and 2013, respectively. For the years ended December 31, 2014 and 2013, $24 and $133 was capitalized to ‘Real estate inventories’, respectively.
	Income taxes
	Income taxes are accounted for under the asset and liability method in accordance with ASC 740, “Accounting for Income Taxes”. Deferred tax assets and liabilities are recognized for future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on the deferred tax assets and liabilities is recognized in income in the period that includes the enactment date.
	Loss per share
	The weighted average shares and share equivalents used to calculate basic and diluted loss per share for the years ended December 31, 2014 and 2013 are presented on the consolidated statement of operations. Restricted stock awards, stock options and warrants for the years ended December 31, 2014 and 2013 are included in the diluted loss per share calculation using the treasury stock method and average market prices during the periods, unless the restricted stock award, stock options and warrants would be anti-dilutive.
	As a result of net losses for the years ended December 31, 2014 and 2013, the following shares have been excluded from the diluted share computation as their inclusion would be anti-dilutive:
		Twelve Months Ended December 31,
		2014			2013
	Restricted stock awards		158			466
	Stock options		198			466
	Warrants		379			759
			735			1,691
	Comprehensive income
	For the years ended December 31, 2014 and 2013, comprehensive income equaled net income; therefore, a separate statement of comprehensive income is not included in the consolidated financial statements.
Segment reporting
We operate our business through three segments: Homebuilding, Multi-family and Real Estate Services. We are currently focused on the Washington, D.C. market.
In our Homebuilding segment, we develop properties with the intent to sell as fee-simple properties or condominiums to individual buyers or to private or institutional investors. Our for-sale products are designed to attract first-time, early move-up, and secondary move-up buyers. We focus on products that we are able to offer for sale in the middle price points within the markets where we operate, avoiding the very low-end and high-end products.
In our Multi-family segment we focus on projects ranging from approximately 75 to 200 units in locations that are supply constrained with demonstrated demand for stabilized assets. We seek opportunities in the multi-family rental market where our experience and core capabilities can be leveraged. We will either position the assets for sale when completed or operate the asset within our own portfolio. Operating the asset for our own account affords us the flexibility of converting the units to condominiums in the future.
In our Real Estate Services segment we pursue projects in all aspects of real estate management including strategic planning, land development, entitlement, property management, sales and marketing, workout and turnaround strategies, financing and general construction. We are able to provide a wide range of construction management and general contracting services to other property owners.
The following disclosure includes the Company’s three reportable segments of Homebuilding, Multi-family and Real Estate Services. Each of these segments operates within the Company’s single Washington, D.C. reportable geographic segment.

The Company allocates sales, marketing and general and administrative expenses to the individual segments based upon specifically allocable costs and, in the absence of direct allocations, based upon its estimate of time allocable to the segment or based upon overall pro rata revenue generation.
Use of estimates
The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts in the financial statements and accompanying notes. Actual results could differ from those estimates. Material estimates are utilized in the valuation of real estate inventories, valuation of deferred tax assets, capitalization of costs, consolidation of variable interest entities and warranty reserves.
Out of Period Adjustment
During the fourth quarter of 2014 the Company recorded an out-of-period adjustment resulting in a $177 decrease to ‘General and administrative’ expense within the consolidated statements of operations. Because this error was not material to any previously filed consolidated financial statements and the impact of correcting this error in the current period is not material to our 2014 consolidated financial statements, the Company recorded the correction of this error in the fourth quarter of 2014, the period in which the error was identified.

Certain amounts in the prior year financial statements have been reclassified to conform to the current-year presentation. The impact of the reclassifications made to prior year amounts is not material and did not affect net loss.
Recent accounting pronouncements
In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, (“ASU 2014-09”). ASU 2014-09 provides a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. ASU No. 2014-09 will require an entity to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This update creates a five-step model that requires entities to exercise judgment when considering the terms of the contract(s) which include (i) identifying the contract(s) with the customer, (ii) identifying the separate performance obligations in the contract, (iii) determining the transaction price, (iv) allocating the transaction price to the separate performance obligations, and (v) recognizing revenue when each performance obligation is satisfied. ASU 2014-09 will be effective for fiscal year beginning after December 1, 2017 and subsequent interim periods. The Company has the option to apply the provisions of ASU 2014-09 either retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of applying this ASU recognized at the date of initial application. Early adoption is not permitted. The Company is currently evaluating the method and impact the adoption of ASU 2014-09 will have on the Company’s consolidated financial statements.
Other accounting pronouncements issued or effective during the year ended December 31, 2014 are not applicable to us and are not anticipated to have an effect on our consolidated financial statements.

Consolidation of Variable Interest Entities	12 Months Ended
	Dec. 31, 2014
Accounting Policies [Abstract]
Consolidation of Variable Interest Entities	3. CONSOLIDATION OF VARIABLE INTEREST ENTITIES
	GAAP requires a variable interest entity (“VIE”) to be consolidated by the company that is the primary beneficiary. The primary beneficiary of a VIE is the entity that has both of the following characteristics: (a) the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance and (b) the obligation to absorb losses of the VIE that could potentially be significant to the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE. Entities determined to be VIEs, for which we are not the primary beneficiary, are accounted for under the equity method. Comstock’s variable interests in VIEs may be in the form of (1) equity ownership, (2) contracts to purchase assets and/or (3) loans provided and or guaranteed to a VIE. We examine specific criteria and use judgment when determining if Comstock is the primary beneficiary of a VIE. Factors considered in determining whether we are the primary beneficiary include risk and reward sharing, experience and financial condition of other partner(s), voting rights, involvement in day-to-day capital and operating decisions and contracts to purchase assets from VIEs.
	Consolidated Real Estate Inventories
	Included within the Company’s real estate inventories at December 31, 2014 and 2013 are several projects that are determined to be VIEs. These entities have been established to own and operate real estate property and were deemed VIEs primarily based on the fact that the equity investment at risk is not sufficient to permit the entities to finance their activities without additional financial support. The Company determined that it was the primary beneficiary of these VIEs as a result of its majority voting and complete operational control of the entities.
	On August 23, 2012, the Company formed New Hampshire Ave. Ventures, LLC, a joint venture of its subsidiary, Comstock Ventures XVI, L.C, and 6000 New Hampshire Avenue, LLC, for the purpose of acquiring, developing and constructing a 111-unit project (the “NHA Project”) in Washington, D.C. The Company evaluated the joint venture and determined that the equity investment at risk is not sufficient to permit the entity to finance its activities without additional financial support. The Company determined that it was the primary beneficiary of the VIE as a result of its complete operational control of the activities that most significantly impact the economic performance and obligation to absorb losses, or receive benefits. The Company contributed its ownership interest in Comstock Ventures XVI, L.C. to Comstock Investors VII, L.C. (“Comstock VII”) on March 13, 2013. During 2014 and 2013, New Hampshire Ave. Ventures, LLC distributed $3.2 million and $0.1 million to its non-controlling interest member, 6000 New Hampshire Avenue, LLC, respectively.
	On September 27, 2012, the Company formed Comstock Eastgate, L.C., a joint venture of the Company and BridgeCom Development II, LLC, for the purpose of acquiring, developing and constructing 66 condominium units in Loudoun County, Virginia (the “Eastgate Project”). The Company evaluated the joint venture and determined that the equity investment at risk is not sufficient to permit the entity to finance its activities without additional financial support. The Company determined that it was the primary beneficiary as a result of its complete operational control of the activities that most significantly impact the economic performance and obligation to absorb losses, or receive benefits. During 2013, the Company and BridgeCom Development I, LLC, each contributed additional equity of $0.6 million. The contributions were used to accelerate construction of the remaining units at the Eastgate Project. During 2014 and 2013, Comstock Eastgate, L.C. distributed $1.9 million and $1.5 million, respectively, to its non-controlling interest member. No additional contributions were made in 2014 and the Company exited the Eastgate Project in the second quarter of 2014 after closing on all 66 units.
	On March 14, 2013, Comstock VII entered into subscription agreements with certain accredited investors (“Comstock VII Class B Members”), pursuant to which the Comstock VII Class B Members purchased membership interests in Comstock VII for an aggregate amount of $7.3 million (the “Comstock VII Private Placement”). The Comstock VII Private Placement was exempt from registration under Section 4(a)(2) of the Securities Act and Rule 506 of Regulation D promulgated under the Securities Act. In connection with the Comstock VII Private Placement, the Company issued 112 warrants for the purchase of shares of the Company’s Class A common stock to the non-affiliated accredited investors, having an aggregate fair value of $146. Comstock VII Class B Members included unrelated third-party accredited investors along with members of the Company’s board of directors and the Chief Financial Officer, the General Counsel and the former Chief Operating Officer, of the Company. The Subscription Agreement provides that the Comstock VII Class B Members are entitled to a cumulative, preferred return of 20% per annum, compounded annually on their capital account balances. After six months, the Company has the right to repurchase the interests of the Comstock VII Class B Members, provided that (i) all of the Comstock VII Class B Members’ interests are acquired, (ii) the purchase is made in cash and (iii) the purchase price equals the Comstock VII Class B Members’ capital account plus an amount necessary to cause the preferred return to equal a cumulative cash on cash return equal to 20% per annum. The Comstock VII Private Placement provides capital related to the current and planned construction of the Company’s following projects: Townes at Shady Grove Metro in Rockville, Maryland consisting of 36 townhomes, Momentum | Shady Grove consisting of 117 condominium units, City Homes at the Hampshires in Washington D.C. consisting of 38 single family residences, Townes at the Hampshires in Washington, D.C. consisting of 73 townhomes, Single Family Homes at the Falls Grove project in Prince William County, Virginia consisting of 19 single family homes and Townes at the Falls Grove project in Prince William County, Virginia consisting of 110 townhomes (collectively, the “Projects”). Proceeds of the Comstock VII Private Placement are to be utilized (A) to provide capital needed to complete the Projects in conjunction with project financing for the Projects, (B) to reimburse the Company for prior expenditures incurred on behalf of the Projects, and (C) for general corporate purposes of the Company. The Company evaluated Comstock VII and determined that the equity investment at risk is not sufficient to permit the entity to finance its activities without additional financial support and the Company was the primary beneficiary as a result of its complete operational control of the activities that most significantly impact the economic performance and its obligation to absorb losses, or receive benefits. Accordingly, the Company consolidates this entity. In 2014, the Company paid total distributions of $8.6 million of which $5.4 million was used to fully redeem the remaining equity interest of the Comstock VII Class B Members. During 2013, the Company paid distributions in the amount of $0.7 million to the Comstock VII Class B Members.
	In December 2013, Comstock Investors VIII, L.C. (“Comstock VIII”) entered into subscription agreements with certain accredited investors (“Comstock VIII Class B Members”), pursuant to which Comstock VIII Class B Members purchased membership interests in Comstock VIII for an aggregate amount of $4.0 million (the “Comstock VIII Private Placement”). The Comstock VIII Private Placement was exempt from registration under Section 4(a)(2) of the Securities Act and Rule 506 of Regulation D promulgated under the Securities Act. In connection with the Comstock VIII Private Placement, the Company issued 102 warrants for the purchase of shares of the Company’s Class A common stock to the non-affiliated accredited investors, having an aggregate fair value of $131. Comstock VIII Class B Members included unrelated third-party accredited investors along with members of the Company’s board of directors and the Company’s former Chief Operating Officer and the Chief Financial Officer. The Comstock VIII Class B Members are entitled to a cumulative, preferred return of 20% per annum, compounded annually on their capital account balances. The Company has the right to repurchase the interests of the Comstock VIII Class B Members at any time, provided that (i) all of the Comstock VIII Class B Members’ interests are acquired, (ii) the purchase is made in cash and (iii) the purchase price equals the Comstock VIII Class B Members’ capital accounts plus an amount necessary to cause the preferred return to equal a cumulative cash on cash return equal to 20% per annum. The proceeds from the Comstock VIII Private Placement will be used for the current and planned construction of the following projects: The Townes at HallCrest in Sterling, Virginia consisting of 42 townhome units, and Townes at Maxwell Square Condominium in Frederick, Maryland consisting of 45 townhome condominium units (collectively, the “Investor VIII Projects”). Proceeds of the Comstock VIII Private Placement are to be utilized (A) to provide capital needed to complete the Investor VIII Projects in conjunction with project financing for the Investor VIII Projects, (B) to reimburse the Company for prior expenditures incurred on behalf of the Investor VIII Projects, and (C) for general corporate purposes of the Company. The Company evaluated Comstock VIII and determined that the equity investment at risk is not sufficient to permit the entity to finance its activities without additional financial support and the Company was the primary beneficiary as a result of its complete operational control of the activities that most significantly impact the economic performance and its obligation to absorb losses, or receive benefits accordingly, the Company consolidates this entity. During 2014, the Company paid distributions in the amount of $0.9 million to the Comstock VIII Class B Members. No distribution was made in 2013.
	At December 31, 2014 and December 31, 2013, the distributions and contributions for the VIE’s discussed above are included within the ‘non-controlling interest’ classification in the consolidated statement of changes in stockholder’s equity.
	At December 31, 2014 and December 31, 2013, total assets of these VIEs were approximately $19.5 million and $46.3 million, respectively, and total liabilities were approximately $13.5 million and $27.4 million, respectively. The classification of these assets is primarily within ‘real estate inventories’ and the classification of liabilities are primarily within ‘notes payable – secured by real estate inventories’ and ‘accounts payable and accrued liabilities’ in the consolidated balance sheets.
	Land purchase options
	The Company typically acquires land for development at market prices under fixed price purchase agreements. The purchase agreements require deposits that may be forfeited if the Company fails to perform under the agreements. The deposits required under the purchase agreements are in the form of cash or letters of credit in varying amounts. The Company may, at its option, choose for any reason and at any time not to perform under these purchase agreements by delivering notice of its intent not to acquire the land under contract. The Company’s sole legal obligation and economic loss for failure to perform under these purchase agreements is typically limited to the amount of the deposit pursuant to the liquidated damages provision contained within the purchase agreement. As a result, none of the creditors of any of the entities with which the Company enters into forward fixed price purchase agreements have recourse to the general credit of the Company.
	The Company does not share in an allocation of either the profit earned or loss incurred by any of these entities with which the Company has fixed price purchase agreements. The Company has concluded that whenever it options land or lots from an entity and pays a significant non-refundable deposit as described above, a variable interest entity is created under the provisions of ASC 810-10, Consolidation. This is because the Company has been deemed to have provided subordinated financial support, which creates a variable interest which limits the equity holder’s returns and may absorb some or all of an entity’s expected theoretical losses if they occur. The Company, therefore, examines the entities with which it has fixed price purchase agreements for possible consolidation by the Company under the provision of ASC 810-10. The Company does not have any contractual or ownership interests in the entities with which it contracts to buy the land. The Company concluded that it does not have the power to direct the activities that most significantly impact the economic performance of the VIEs, including the power to site plan and engineer the developments, finance the parcels under option contract, and develop the raw parcels under option contract into finished lots. The third party retains these rights under the fixed purchase price agreements until title is transferred to the Company upon settlement of the transaction, or a portion of the transactions as defined. Therefore, the Company has not consolidated these VIEs in the consolidated balance sheets.

Real Estate Inventories	12 Months Ended

Real Estate [Abstract]
Real Estate Inventories	4. REAL ESTATE INVENTORIES
	Real estate inventories include land, land development costs, construction and other costs. Real estate held for development and use is stated at cost, or when circumstances or events indicate that the real estate is impaired, at estimated fair value. Real estate held for sale is carried at the lower of cost or fair value less estimated costs to sell. Land, land development and indirect land development costs are accumulated by specific project and allocated to various units within that project using specific identification and allocation based upon the relative sales value, unit or area methods. Direct construction costs are assigned to units based on specific identification. Construction costs primarily include direct construction costs and capitalized field overhead. Other costs are comprised of fees, capitalized interest and real estate taxes. Costs incurred to sell real estate are capitalized to the extent they are reasonably expected to be recovered from the sale of the project and are tangible assets or services performed to obtain regulatory approval of sales. Other selling costs are expensed as incurred.
	For assets held for development and use, a write-down to estimated fair value is recorded when the net carrying value of the property exceeds its estimated undiscounted future cash flows. Estimated fair value is based on comparable sales of real estate in the normal course of business under existing and anticipated market conditions. These evaluations are made on a property-by-property basis whenever events or changes in circumstances indicate that the net book value may not be recoverable.
	If the project is considered held for sale, it is valued at the lower of cost or fair value less estimated selling costs. The evaluation takes into consideration the current status of the property, carrying costs, costs of disposition, various restrictions and any other circumstances that may affect fair value including management’s plans for the property. At December 31, 2013 and 2014, the Company had no projects classified as held for sale.
	In 2012, management evaluated its strategic alternatives with respect to its real estate projects classified as held for sale, Eclipse and Penderbrook, with the objective of creating additional near term liquidity. As a result, a decision was made to market the Potomac Yard project in a bulk sale transaction, rather than by selling directly to prospective home buyers, significantly accelerating absorption. During the first quarter of 2013, in the absence of a prospective bulk sale buyer and as a result of the increased sales activity, the Company revised its previous disposition strategy and reversed a previously recorded impairment charge of $0.7 million to properly reflect the for sale project at far market value less costs to sell, consistent with the provisions of the ASC 360. During the first half of 2013, the Company sold all remaining units at the Eclipse and Penderbrook projects.
	During 2014, we wrote-off $2.7 million in land and land development costs related to the Momentum | Shady Grove project. The write-off occurred in December 2014 due to a revision in our previous disposition strategy. The impairment charge was calculated using a discounted cash flow analysis model, which is dependent upon several subjective factors, including the selection of an appropriate discount rate, estimated average sales price and estimated sales rates. In performing our impairment modeling, we must select what we believe is an appropriate discount rate based on current market cost of capital and return expectations. During 2013, we wrote-off $1.1 million of due diligence and entitlement pursuit costs related to the BLVD Newell project, which was controlled under a land purchase option contract. The write-off occurred due to the Company’s unsuccessful attempt to obtain entitlement approvals and as a result, such accumulated costs were determined to be unrecoverable.
	After impairments and write-offs, real estate held for development and sale consists of the following:
		December 31,		December 31,
		2014		2013
	Land and land development costs	$	22,487	$	26,805

	We are in active discussions with our lenders with respect to the 2015 maturities and are seeking extensions and modifications to the loans as necessary. The current performance of the projects and our early discussions with our lenders indicates that we will likely be successful in extending or modifying these loans, though no assurances can be made that we will be successful in these efforts.
	Construction, development and mezzanine debt - secured
	The Company enters into secured acquisition and development loan agreements to purchase and develop land parcels. In addition, the Company enters into secured construction loan agreements for the construction of its real estate inventories. The loans are repaid with proceeds from home closings based upon a specific release price, as defined in each respective loan agreement.
	As of December 31, 2014 and 2013, the Company had secured construction revolving credit facilities with a maximum loan commitment of $33.4 million and $21.9 million, respectively. The Company may borrow under these facilities to fund its home building activities. The amount the Company may borrow is subject to applicable borrowing base provisions and the number of units under construction, which may also limit the amount available or outstanding under the facilities. The facilities are secured by deeds of trust on the real property and improvements thereon, and the borrowings are repaid with the net proceeds from the closings of homes sold, subject to a minimum release price. As of December 31, 2014 and 2013, the Company had approximately $26.9 million and $14.7 million, respectively, of unused loan commitments. The Company had $6.5 million and $4.1 million of outstanding construction borrowings as of December 31, 2014 and 2013, respectively. On March 22, 2015, $2.6 million of the outstanding construction revolving credit facilities related to the Townes at Shady Grove Metro project with Eagle Bank matured, and was extended on April 8, 2015. The extensions provide for a new maturity date of June 22, 2015. All other credit facilities have maturity dates ranging from May 2015 to July 2016, including extensions subject to certain conditions. Interest rates charged under these facilities include the London Interbank Offered Rate (“LIBOR”) and prime rate pricing options, subject to minimum interest rate floors. At December 31, 2014 and 2013, the weighted average interest rate on the Company’s outstanding construction revolving facility was 5.1% and 5.3%, respectively.
	As of December 31, 2014 and 2013, the Company had approximately $28.0 million and $26.1 million, respectively, of aggregate acquisition and development maximum loan commitments of which $13.7 million and $12.3 million, respectively, was outstanding. On March 22, 2015, $4.5 million of the outstanding acquisition and development loans related to the Townes at Shady Grove Metro and Momentum | Shady Grove projects with Eagle Bank matured, and was extended on April 8, 2015. The extensions provide for a new maturity date of June 22, 2015. All other loans have maturity dates ranging from May 2015 to July 2016, including auto extension subject to certain conditions and bears interest at a rate based on LIBOR and Prime Rate pricing options, with interest rate floors ranging from 4.5% to 5.75%. As of December 31, 2014 and 2013, the weighted average interest rates were 4.8% per annum and 4.9% per annum, respectively.
	As of December 31, 2014, the Company had three secured mezzanine loans. The first mezzanine loan has a maximum loan commitment and outstanding balance of $3.0 million at December 31, 2014 and December 31, 2013. This mezzanine financing was utilized to acquire land for the development of the City Homes at the Hampshires and the Townes at the Hampshires projects and is secured by the second deed of trust. This first mezzanine loan bears a fixed interest rate of 13.5% per annum paid on a monthly basis, with the full principal balance due at maturity, September 22, 2015.
	The second and third mezzanine loans are being used to finance the development of the Townes at Shady Grove Metro and Momentum | Shady Grove projects. The maximum principal commitment amount of these loans was $3.2 million of which $2.8 million of principal and accrued interest was outstanding as of December 31, 2014. These financings carry an interest rate of 12% of which 6% is paid on a monthly basis with the remaining 6% being accrued and paid at maturity. These financings matured in March 2015, and were extended on April 8, 2015. The extensions provide for a new maturity date of June 22, 2015. All other terms of the original agreements remain in full force and effect. These financings are guaranteed by the Company and our CEO.
	Line of credit – secured
	At December 31, 2014, the Company had a secured revolving line of credit amounting to $5.0 million of which $2.4 million was outstanding. This line of credit is secured by the first priority security interest in the Company’s wholly owned subsidiaries’ in the Washington D.C, metropolitan area and is used to finance the predevelopment related expenses and deposits for current and future projects. This line of credit bears a variable interest rate tied to a one-month LIBOR plus 3.25% per annum, with an interest rate floor of 5.0% and matures on July 15, 2015 with an extension option for an additional twelve months provided that the Company meets certain conditions. This line of credit also calls for the Company to adhere to financial covenants such as, minimum EBITDA, minimum net worth and minimum liquidity, all measured quarterly on a trailing twelve month basis. As of December 31, 2014, the Company was in compliance with all financial covenants dictated by the line of credit agreement. This line of credit is guaranteed by our CEO.
	Unsecured note
	At December 31, 2014 and December 31, 2013, the Company had $2.1 million and $2.6 million, respectively, outstanding to a major bank under a 10-year unsecured note. Interest is charged on this financing at LIBOR plus 2.2%. At December 31, 2014 and 2013, the interest rate was 2.4%. The maturity date of this financing is December 28, 2018. The Company is required to make monthly principal and interest payments through maturity.
	Notes payable to affiliate—unsecured
	On March 14, 2013, Stonehenge Funding, LC (“Stonehenge”), an entity wholly-owned by our Chief Executive Officer, entered into an Extension Agreement of the Amended and Restated Senior Note with the Company to extend the maturity date of the financing arrangement to January 1, 2016. Beginning on April 1, 2013, the Company is required to pay $50 monthly to Stonehenge, to be allocated first to accrued interest and then to the outstanding principal. Interest is charged to the loan based on LIBOR plus 3% per annum. As of December 31, 2014 and 2013, the interest rate was 3.6% per annum. The Company had approximately $4.2 million and $4.7 million of outstanding borrowings as of December 31, 2014 and December 31, 2013, respectively.
	On October 17, 2014, Comstock Growth Fund, L.C. (CGF), an administrative entity managed by the Company, was created for purposes of raising capital through a private placement offering. CGF entered into a subscription agreement with Comstock Development Services, LC (“CDS”), an entity wholly-owned by our Chief Executive Officer, pursuant to which CDS purchased membership interests in CGF for an initial aggregate principal amount of $10 million and received additional commitments from members of the Company’s management and board of directors (the “CGF Private Placement”). CGF is offering additional interests for sale to third party accredited investors, which if fully subscribed would increase the total capital raised by CGF up to $20 million. Purchasers other than CDS who purchase an amount of interests may receive warrants that represent the right to purchase an aggregate amount of between 500,000 to 1,000,000 shares of the Company’s Class A common stock, depending upon the investment amount. As of December 31, 2014, we issued 241 warrants representing the right to purchase shares of the Company’s Class A common stock to CGF having an aggregate fair value of $162 that was considered as a debt discount. In calculating the fair value of the warrants the Company used the Black-Scholes pricing model based upon the date the funds were contributed to CGF. The Company amortizes the debt discount over the three year term of the loan to interest expense.
	Simultaneously, on October 17, 2014, the Company entered into a unsecured promissory note with CGF whereby CGF made a loan to the Company in the initial principal amount of $10 million and a maximum amount available for borrowing of up to $20 million with a three year term (the “Original Promissory Note”. The loan bears interest at a floating rate based on the 30 day LIBOR plus 9.75% per annum with a 10% floor per annum. Interest payments will be made monthly in arrears. There is a principal curtailment requirement of 10% annually based on the average outstanding balance for the prior year. The loan will be used by the Company (i) to finance the Company’s current and future development pipeline, (ii) to repay all or a portion of the Company’s prior private placements; (iii) to repay all or a portion of the Company’s project mezzanine loans, and (iv) for general corporate purposes. The Company is the administrative manager of CGF but does not own any membership interests. The Company had approximately $11.3 million of outstanding borrowings, net of discounts, as of December 31, 2014. As of December 31, 2014, the interest rate was 10.0% per annum.
	On December 18, 2014, CGF entered into amended and restated subscription agreements with CDS, management and members of the Company’s board of directors who participated in the CGF Private Placement (the “Amended Private Placement”). Under the Amended Private Placement, in addition to the warrants as described above, purchasers of the interests will receive a certain amount shares of our Class A common stock that CGF acquired, depending upon the investment amount. As of December 31, 2014, the Company entered into a commitment to grant 1,028 shares of the Company’s Class A common stock in connection with the CGF Private Placement. The commitment was treated and recognized as a derivative liability that is marked to market at the end of each quarter. The Company determined the fair value of the stock based on the closing price of our stock on the dates the funds were received by CGF. As of December 31, 2014, the fair value of the stocks, $1,091, was included within ‘Accounts payable and accrued liabilities’ with a corresponding offset to ‘Notes payable - due to affiliates’ in the form of debt discount on the consolidated balance sheets. The mark to market gain on the derivative liability, $32, was included within ‘Other income’ on the consolidated statement of operations with a corresponding offset to the derivative liability within ‘Accounts payable and accrued liabilities’ on the consolidated balance sheets as of December 31, 2014. The Company amortizes the debt discount over the three year term of the loan to interest expense.
	Simultaneously, on December 18, 2014, the Company entered into an amended and restated Original Promissory Note pursuant to which the maximum amount for borrowing was increased from $20 million to $25 million. All of the other terms of the Original Promissory Note remained the same.

Restricted Stock, Stock Options and Other Stock Plans	12. RESTRICTED STOCK, STOCK OPTIONS AND OTHER STOCK PLANS
	On December 14, 2004, the Company adopted the 2004 Long-Term Compensation Plan (the “Plan”). The Plan provides for the issuance of stock options, stock appreciation rights, or SARs, restricted stock, deferred stock, dividend equivalents, bonus stock and awards in lieu of cash compensation, other stock-based awards and performance awards. Any shares issued under the Plan typically vest over service periods that range from one to five years. Stock options issued under the plan expire 10 years from the date they are granted.
	The Plan provided an initial authorization of 2.5 million shares of Class A common stock for issuance and allows an automatic annual increase equal to the lesser of (i) 3% of the Class A common stock outstanding (ii) 750 shares or (iii) such lesser amount as may be determined by the Company’s board of directors. On April 27, 2012, the Company authorized an increase in the number of shares of our Class A common stock reserve to 7.1 million. On June 22, 2012, the Company’s stockholders approved the Amended and Restated 2004 Long-Term Incentive Compensation Plan, including an increase in the reserve, with an automatic annual increase on January 1 of each successive year of the lesser of (i) 3% of the Class A common stock outstanding or (ii) 750 shares. As of December 31, 2014, there were 2.2 million shares available for issuance under the Plan (as amended).
	The fair value of each option award is calculated on the date of grant using the Black-Scholes option pricing model and certain subjective assumptions. Expected volatilities are calculated based on our historical trading activities. We estimate forfeitures using a weighted average historical forfeiture rate. Our estimates of forfeitures will be adjusted over the requisite service period based on the extent to which actual forfeitures differ, or are expected to differ, from their estimate. The risk-free rate for the periods is based on the U.S. Treasury rates in effect at the time of grant. The expected term of options is based on the simplified method which assumes that the option will be exercised midway between the vesting date and the contractual term of the option. The Company is able to use the simplified method as the options qualify as “plain vanilla” options as defined by ASC 718 – Stock Compensation.
	The following table summarizes the assumptions used to calculate the fair value of options during 2014 and 2013:
		2014			2013

	As of December 31, 2014 and 2013, there was $0.5 million and $0.8 million, respectively, of unrecognized compensation cost related to stock options and restricted stock issuances granted under the Plan. The Company intends to issue new shares of its common stock upon vesting of restricted stock grants or the exercise of stock options.
	In November 2014, our board of directors approved a new share repurchase program authorizing the Company to repurchase up to three million shares of its Class A common stock in one or more open market or privately negotiated transactions depending on market price and other factors. We expect to use available cash on hand and cash generated from operating activities to fund the common share repurchase program.
	For the year ended December 31, 2014, we purchased 95,400 shares of our Class A common stock under the repurchase program for approximately $103 (including commissions of $2). At December 31, 2014, 2.9 million shares of our Class A common stock authorized for repurchase remain available for repurchase. See Item 5 for further discussion on our common stock repurchase program.

Severance and Restructuring	14. SEVERANCE AND RESTRUCTURING
	In connection with the departure of Gregory V. Benson, the Company’s former President and Chief Operating Officer, in May 2014, the Company entered into a Separation Agreement with Mr. Benson. The Separation Agreement provides for cash severance payment and incremental healthcare insurance through COBRA. The severance cost was $597, paid in 36 semi-monthly installments effective May 1, 2014. The total healthcare cost was $14 for 12 months beginning May 1, 2014. Additionally, the Company recorded $131 against stock based compensation during the year to account for the forfeiture of the stock options and restricted stock awards previously granted to Mr. Benson. The severance and restructuring charge was included in ‘General and administrative’ expenses in the accompanying consolidated statements of operations. The remainder of the accrual of the severance cost, $336, as of December 31, 2014 is included in the ‘Accounts payable and accrued liabilities’ in the accompanying consolidated balance sheets. There were no severance and restructuring charges in 2013.
	In addition, per the Separation Agreement, the Company has a call option, but not an obligation, to purchase all or a portion of Mr. Benson’s shares of Class A and Class B common stock of the Company at $1.09 per share by June 30, 2015. If the Company exercises the option and elects to repurchase less than all of his shares of Class A and Class B common stock in a single transaction, then the following applies to each transaction: i) each transaction should include the purchase of a pro-rata portion of the Class A and Class B common stock; ii) the first purchase must include a minimum of 1,000,000 of Mr. Benson’s Class A and Class B common stock (cumulative number of Mr. Benson’s Class A and Class B common stock); and (iii) each subsequent purchase must include a minimum of 100,000 Class A and Class B Common stock (cumulative number of Mr. Benson’s Class A and Class B common stock) until all shares of Class A and Class B common stock have been purchased. Mr. Benson also forfeited all unvested stock options and restricted stock awards outstanding as of the date of his departure. The Company recorded the fair value of the call option, which was considered to be a freestanding equity linked financial instrument, and the corresponding contribution of the call option to the Company by Mr. Benson as offsetting entries within “Additional paid-in-capital” within the consolidated balance sheets. The impact of the call option resulted in a net impact of $0, in the consolidated statement of changes in stockholders’ Equity. As of December 31, 2014, the Company has not exercised any portion of its option under the agreement

	Litigation
	Currently, we are not subject to any material legal proceedings. From time to time, however, we are named as a defendant in legal actions arising from our normal business activities. Although we cannot accurately predict the amount of our liability, if any, that could arise with respect to legal actions pending against us, we do not expect that any such liability will have a material adverse effect on our financial position, operating results or cash flows. We believe that we have obtained adequate insurance coverage, rights to indemnification, or where appropriate, have established reserves in connection with these legal proceedings.
	Letters of credit, performance bonds and compensating balances
	The Company has commitments as a result of contracts entered into with certain third parties, primarily local governmental authorities, to meet certain performance criteria as outlined in such contracts. The Company is required to issue letters of credit and performance bonds to these third parties as a way of ensuring that the commitments entered into are met. These letters of credit and performance bonds issued in favor of the Company and/or its subsidiaries mature on a revolving basis, and if called into default, would be deemed material if assessed against the Company and/or its subsidiaries for the full amounts claimed. In some circumstances, we have negotiated with our lenders in connection with foreclosure agreements for the lender to assume certain liabilities with respect to the letters of credit and performance bonds. We cannot accurately predict the amount of any liability that could be imposed upon the Company with respect to maturing or defaulted letters of credit or performance bonds. At December 31, 2014 and 2013, the Company had issued $4.3 million in letters of credit. At December 31, 2014, the Company had $4.4 million and $2.1 million in performance and payment bonds, respectively, outstanding to third parties. No amounts have been drawn against these letters of credit or performance bonds.
	We are required to maintain compensating balances in escrow accounts as collateral for certain letters of credit, which are funded upon settlement and release of units. The cash contained within these escrow accounts is subject to withdrawal and usage restrictions.

Fair Value Disclosures [Abstract]
Fair Value Disclosures	16. FAIR VALUE DISCLOSURES
	ASC 820 establishes a framework for measuring fair value, expands disclosures regarding fair value measurements and defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC 820 specifies a hierarchy of valuation techniques based on whether the inputs to a fair value measurement are considered to be observable or unobservable in a marketplace. The three measurement input levels for determining fair value are as follows
		•		Fair values determined by Level 1 inputs utilize quoted prices in active markets for identical assets or liabilities that the Company has the ability to access.
		•		Fair values determined by Level 2 inputs utilize inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include quoted prices for similar assets and liabilities in active markets, and inputs other than quoted prices that are observable for the asset or liability, such as interest rates and yield curves that are observable at commonly quoted intervals.
		•		Level 3 inputs are unobservable inputs for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability. An asset’s or liability’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement.
	The carrying amounts reported in the consolidated balance sheets for cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities are reasonable estimates of their fair values based on their short maturities.
	The fair value of fixed and floating rate debt is based on unobservable inputs (Level 3 inputs). The following table summarizes the fair value of fixed and floating rate debt and the corresponding carrying value of fixed and floating rate debt as of:
			December 31,		December 31,
			2014		2013
	Carrying amount		$	45,931	$	29,968
	Fair value		$	44,854	$	27,943
	Fair value estimates are made at a specific point in time, based on relevant market information about the financial instruments. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore, cannot be determined with precision. Changes in assumptions could significantly affect the estimates.
	The Company may also value its non-financial assets and liabilities, including items such as real estate inventories and long lived assets, at fair value on a non recurring basis if it is determined that impairment has occurred. Such fair value measurements use significant unobservable inputs and are classified as Level 3. See Notes 2 and 4 for further discussion of the valuation techniques and inputs used.
	In 2014, we wrote-off $2.7 million in land and land development costs related to the Momentum | Shady Grove project. The write-off occurred in December 2014 due to a revision in our previous disposition strategy. The impairment charge was calculated using a discounted cash flow analysis model, which is dependent upon several subjective factors, including the selection of an appropriate discount rate, estimated average sales price and estimated sales rates. In performing our impairment modeling, we must select what we believe is an appropriate discount rate based on current market cost of capital and return expectations. During 2013, we wrote-off $1.1 million in due diligence and entitlement pursuit costs related to the BLVD Newell project, which was controlled under a land purchase option contract. The write-off occurred in December 2013 due to the Company’s unsuccessful attempt to obtain entitlement approvals.
	Due to a change to an individual unit retail sale strategy from our previous bulk sale disposition strategy, we reversed a previously recorded impairment charge of $0.7 million during the year ended December 31, 2013. See real estate inventories in Note 4 in the accompanying consolidated financial statements for further discussion and the basis for determining the impairment charges and reversals.

Income Tax Disclosure [Abstract]
Income Taxes	18. INCOME TAXES
	The effective tax rate for the years ended December 31, 2014 and 2013 was 4.5% and 17.1%, respectively after adjustment for non-includable partnership income arising from non-controlling interests. This resulted in $0.4 million and $0.3 million in tax expense for the twelve month periods ended December 31, 2014 and 2013, respectively. This tax arises from taxable income generated in the District of Columbia against which the Company has no tax net operating losses to offset.
	Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. The Company recorded valuation allowances for certain tax attributes and other deferred tax assets. At this time, sufficient uncertainty exists regarding the future realization of these deferred tax assets through future taxable income. If, in the future, the Company believes that it is more likely than not that these deferred tax benefits will be realized, the valuation allowances will be reversed. With a full valuation allowance, any change in the deferred tax asset or liability is fully offset by a corresponding change in the valuation allowance.
	The Company currently has approximately $123 million in federal and state NOLs, which based on current statutory tax rates, have potential fair value of approximately $48 million in tax savings. If unused, these NOLs will begin expiring in 2028. Under Code Section 382 (“Section 382”) rules, if a change of ownership is triggered, the Company’s NOL assets and possibly certain other deferred tax assets may be impaired. We estimate that as of December 31, 2014, the cumulative shift in ownership of the Company’s stock would not cause an impairment of our NOL asset. However, if an ownership change were to occur, the Section 382 limitation would not be expected to materially impact the Company’s financial position or results of operations as of December 31, 2014, because of the Company’s full valuation allowance on its net deferred tax assets.
	The Company’s ability to use its NOLs (and in certain circumstances, future built-in losses and depreciation deductions) can be negatively affected if there is an “ownership change” as defined under Section 382. In general, an ownership change occurs whenever there is a shift in ownership by more than 50 percentage points by one or more 5% stockholders over a specified time period (generally three years). Given Section 382’s broad definition, an ownership change could be the unintended consequence of otherwise normal market trading in the Company’s stock that is outside of the Company’s control. In an effort to preserve the availability of these NOLs, Comstock adopted a Section 382 stockholder rights plan. This plan expired in May 2014. On March 27, 2015, Comstock adopted a new Internal Revenue Code Section 382 stockholder rights plan (the “Rights Plan”) that will be submitted to a vote of the Company’s stockholders at the 2015 Annual Meeting of Stockholders. The Rights Plan was adopted to reduce the likelihood of such an unintended “ownership change” and thus assist in preserving the value of these tax benefits. Similar plans have been adopted by a number of companies holding similar significant tax assets over the past several years.
	The Company has not recorded any accruals related to uncertain tax positions as of December 31, 2014 and 2013, respectively. We file U.S. and state income tax returns in jurisdictions with varying statutes of limitations. The 2011 through 2013 tax years remain subject to examination by federal and most state tax authorities.

Subsequent Events	20. SUBSEQUENT EVENTS
	On February 20, 2015, the Company entered into an acquisition, development and construction loan agreement with a local bank for $7.3 million in connection with its Stone Ridge single-family home project in Loudoun County, Virginia. The loan provides for a variable interest rate of Prime plus 0.5% per annum with an interest rate floor of 4.5% per annum. This loan matures on February 20, 2017, and has an automatic extension date through February 20, 2018 as long as certain conditions are met. This loan is collateralized by the first deed of trust on the project and guaranteed by the Company’s Chief Executive Officer.
	On March 17, 2015, the Company entered into a development and construction loan agreement with Cardinal Bank for $6.7 million in connection with the Two Rivers I project. The loan provides for a variable interest rate of LIBOR plus 3.5% per annum with an interest rate floor of 4.625% per annum. This loan matures on March 17, 2018. This loan is collateralized by the first deed of trust on the project and guaranteed by the Company’s Chief Executive Officer.
	On March 18, 2015, the board of directors approved the adoption and execution of a Section 382 Rights Agreement and authorized and declared a dividend distribution of one preferred stock purchase right (a “Right”) for each share of our Class A common stock or Class B common stock of the Company outstanding to stockholders of record at the close of business on May 16, 2015. The description and terms of the Rights are set forth in the Section 382 Rights Agreement (the “Rights Agreement”) dated March 27, 2015 by and between the Company and American Stock Transfer & Trust Company, LLC. Each Right entitles the registered holder to purchase from the Company a unit consisting of one one-thousandth of a share of Series A Junior Participating Preferred Stock, par value $0.01 per share, at a purchase price of $12.80 per Unit, subject to adjustment. The Rights Agreement was adopted to preserve the Company’s tax assets associated with net operating loss carryforwards under Section 382 of the Internal Revenue Code. The Rights Agreement will be submitted to a vote of the Company’s stockholders at the 2015 Annual Meeting of Stockholders.
	On April 8, 2015, the Company extended its revolving construction, acquisition, development loans with Eagle Bank. Simultaneously, the Company also extended its mezzanine financing with Eagle Commercial Ventures. The extensions provide for a new maturity date of June 22, 2015. All other terms of the original agreements remain in full force and effect.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2014
Accounting Policies [Abstract]
Basis of presentation	Basis of presentation
	The accompanying consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) and include the accounts of the Company and all of its majority-owned and controlled subsidiaries. All significant intercompany accounts and transactions have been eliminated. Investments in 50% or less owned partnerships and affiliates are accounted for using the equity method unless it is determined that the Company has control of the entity, in which case the entity would be consolidated. The Company had one joint venture investment accounted for using the equity method as of December 31, 2014 and 2013.
Cash and cash equivalents and restricted cash	Cash and cash equivalents and restricted cash
	Cash and cash equivalents are comprised of cash and short-term investments with maturities of three months or less when purchased. At times, the Company may have deposits with institutions in excess of federally insured limits. We monitor the cash balances in our bank accounts and adjust the balance as appropriate. To date, we have experienced no loss or lack of access to our invested cash or cash equivalents; however, we can provide no assurance that access to our cash and cash equivalents will not be impacted by adverse conditions in the financial market. At December 31, 2014 and 2013, the Company had restricted cash of $1.8 million and $2.5 million, respectively, which includes $1.0 million and $2.0 million in deposits, respectively, with an insurance provider as security for future claims.
Real estate inventories	Real estate inventories
	Real estate inventories include land, land development costs, construction and other costs. Real estate held for development and use is stated at cost, or when circumstances or events indicate that the real estate is impaired, at estimated fair value. Real estate held for sale is carried at the lower of cost or fair value less estimated costs to sell. Land, land development and indirect land development costs are accumulated by specific project and allocated to various units within that project using specific identification and allocation based upon the relative sales value, unit or area methods. Direct construction costs are assigned to units based on specific identification. Construction costs primarily include direct construction costs and capitalized field overhead. Other costs are comprised of fees, capitalized interest and real estate taxes. Costs incurred to sell real estate are capitalized to the extent they are reasonably expected to be recovered from the sale of the project and are tangible assets or services performed to obtain regulatory approval of sales. Other selling costs are expensed as incurred.
	If the project is considered held for sale, it is valued at the lower of cost or fair value less estimated selling costs. The evaluation takes into consideration the current status of the property, carrying costs, costs of disposition, various restrictions and any other circumstances that may affect fair value including management’s plans for the property. For assets held for development and use, a write-down to estimated fair value is recorded when the net carrying value of the property exceeds its estimated undiscounted future cash flows. Estimated fair value is based on comparable sales of real estate in the normal course of business under existing and anticipated market conditions. These evaluations are made on a property-by-property basis whenever events or changes in circumstances indicate that the net book value may not be recoverable.
Capitalized interest and real estate taxes	Capitalized interest and real estate taxes
	Interest and real estate taxes incurred relating to the development of lots and parcels are capitalized to real estate inventories during the active development period, which generally commences when borrowings are used to acquire real estate assets and ends when the properties are substantially complete or the property becomes inactive. A project becomes inactive when development and construction activities have been suspended indefinitely. Interest is capitalized based on the interest rate applicable to specific borrowings or the weighted average of the rates applicable to other borrowings during the period. Interest and real estate taxes capitalized to real estate inventories are expensed as a component of cost of sales as related units are sold. The following table is a summary of interest and real estate taxes incurred, capitalized and expensed for units settled:
		Twelve Months Ended December 31
		2014			2013
	Total interest incurred and capitalized	$	2,557		$	1,884
	Total real estate taxes incurred and capitalized		234			181
	Total interest and real estate taxes incurred and capitalized	$	2,791		$	2,065
	Interest expensed as a component of cost of sales	$	557		$	2,146
	Real estate taxes expensed as a component of cost of sales		175			311
	Interest and real estate taxes expensed as a component of cost of sales	$	732		$	2,457
	When a project becomes inactive, its interest, real estate taxes and indirect production overhead costs are no longer capitalized but rather expensed in the period in which they are incurred. Following is a breakdown of the interest, real estate taxes and indirect costs expensed related to inactive projects reported in real estate inventories:
		Twelve Months Ended December 31,
		2014			2013
	Total interest incurred and expensed for inactive projects	$	—		$	73
	Total real estate taxes incurred and expensed for inactive projects		26			49
	Total production overhead incurred and expensed for inactive projects		—			286
		$	26		$	408
Property, plant and equipment	Property, plant and equipment
	Property, plant and equipment are carried at cost less accumulated depreciation and are depreciated on the straight-line method over their estimated useful lives as follows:
	Furniture and fixtures		7 years
	Office equipment		5 years
	Computer equipment and capitalized software		3 years
	Leasehold improvements		Life of related lease
	When assets are retired or otherwise disposed of, the cost and accumulated depreciation are removed from their separate accounts and any gain or loss on sale is reflected in operations. Expenditures for maintenance and repairs are charged to expense as incurred.
Warranty reserve	Warranty reserve
	Warranty reserves for units settled are established to cover potential costs for materials and labor with regard to warranty-type claims expected to arise during the typical one-year warranty period provided by the Company or within the two-year statutorily mandated structural warranty period for condominiums. Because the Company typically subcontracts its homebuilding work, subcontractors are required to provide the Company with an indemnity and a certificate of insurance prior to receiving payments for their work. Claims relating to workmanship and materials are generally the primary responsibility of the subcontractors and product manufacturers. The warranty reserve is established at the time of closing, and is calculated based upon historical warranty cost experience and current business factors. This reserve is an estimate and actual warranty costs could vary from these estimates. Variables used in the calculation of the reserve, as well as the adequacy of the reserve based on the number of homes still under warranty, are reviewed on a periodic basis. Warranty claims are directly charged to the reserve as they arise.
	During 2008, the Company recorded an additional $241 in warranty reserves to cover costs and claims related to a project in North Carolina. In August 2014, the Company settled the claim for $59, including legal costs, releasing the Company from future claims and costs related to this project and accordingly reduced the warranty reserve by $182. The warranty release was recorded as a reduction to homebuilding cost of sales in the third quarter of 2014.
	In the third quarter of 2013, the Company settled a legal claim related to one of its projects in Virginia for $0.2 million, releasing the Company from future warranty claims related to this project and accordingly reduced the warranty reserve by $0.4 million. The warranty release was recorded as a reduction to homebuilding cost of sales in the third quarter of 2013.
	The following table is a summary of warranty reserve activity which is included in accounts payable and accrued liabilities:
		Years ended
		December 31,
		2014			2013
	Balance at beginning of period	$	510		$	963
	Additions		454			262
	Releases and/or charges incurred		(472	)		(715	)
	Balance at end of period	$	492		$	510
Revenue recognition	Revenue recognition
	The Company recognizes revenues and related profits or losses from the sale of residential properties and units, finished lots and land sales when closing has occurred, full payment has been received, title and possession of the property has transferred to the buyer and the Company has no significant continuing involvement in the property. Other revenues include revenue from land sales, rental revenue from leased multi-family units – which is recognized ratably over the terms of the respective leases, revenue from construction services – which is recognized under the percentage-of-completion method, and revenue earned from management and administrative support services provided to related parties – which is recognized as the services are provided.
Advertising costs	Advertising costs
	The total amount of advertising costs charged for the year ended December 31, 2014 was $743, of which $730 was charged to sales and marketing and $13 was charged to general and administrative expenses. The total amount of advertising costs charged for the year ended December 31, 2013 was $614, of which $577 was charged to sales and marketing, $32 was charged to cost of sales and $5 was charged to general and administrative expenses.
Stock compensation	Stock compensation
	As discussed in Note 12, the Company sponsors stock option plans and restricted stock award plans. The Company accounts for its share-based awards pursuant to Accounting Standards Codification (“ASC”) 718, Share Based Payments. ASC 718 requires all share-based payments to employees, including grants of employee stock options, to be recognized in the financial statements over the vesting period based on their fair values at the date of grant. For the year ended December 31, 2014 and 2013, total stock-based compensation cost was $319 and $616, respectively. Of this amount, $271 and $477 was charged to ‘general and administrative’ expenses for the years ended December 31, 2014 and 2013, respectively, and $24 and $6 was charged to ‘cost of sales-other’ for the years ended December 31, 2014 and 2013, respectively. For the years ended December 31, 2014 and 2013, $24 and $133 was capitalized to ‘Real estate inventories’, respectively.
Income taxes	Income taxes
	Income taxes are accounted for under the asset and liability method in accordance with ASC 740, “Accounting for Income Taxes”. Deferred tax assets and liabilities are recognized for future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on the deferred tax assets and liabilities is recognized in income in the period that includes the enactment date.
Loss per share	Loss per share
	The weighted average shares and share equivalents used to calculate basic and diluted loss per share for the years ended December 31, 2014 and 2013 are presented on the consolidated statement of operations. Restricted stock awards, stock options and warrants for the years ended December 31, 2014 and 2013 are included in the diluted loss per share calculation using the treasury stock method and average market prices during the periods, unless the restricted stock award, stock options and warrants would be anti-dilutive.
	As a result of net losses for the years ended December 31, 2014 and 2013, the following shares have been excluded from the diluted share computation as their inclusion would be anti-dilutive:
		Twelve Months Ended December 31,
		2014			2013
	Restricted stock awards		158			466
	Stock options		198			466
	Warrants		379			759
			735			1,691
Comprehensive income	Comprehensive income
	For the years ended December 31, 2014 and 2013, comprehensive income equaled net income; therefore, a separate statement of comprehensive income is not included in the consolidated financial statements.
Segment reporting	Segment reporting
	We operate our business through three segments: Homebuilding, Multi-family and Real Estate Services. We are currently focused on the Washington, D.C. market.
	In our Homebuilding segment, we develop properties with the intent to sell as fee-simple properties or condominiums to individual buyers or to private or institutional investors. Our for-sale products are designed to attract first-time, early move-up, and secondary move-up buyers. We focus on products that we are able to offer for sale in the middle price points within the markets where we operate, avoiding the very low-end and high-end products.
	In our Multi-family segment we focus on projects ranging from approximately 75 to 200 units in locations that are supply constrained with demonstrated demand for stabilized assets. We seek opportunities in the multi-family rental market where our experience and core capabilities can be leveraged. We will either position the assets for sale when completed or operate the asset within our own portfolio. Operating the asset for our own account affords us the flexibility of converting the units to condominiums in the future.
	In our Real Estate Services segment we pursue projects in all aspects of real estate management including strategic planning, land development, entitlement, property management, sales and marketing, workout and turnaround strategies, financing and general construction. We are able to provide a wide range of construction management and general contracting services to other property owners.
	The following disclosure includes the Company’s three reportable segments of Homebuilding, Multi-family and Real Estate Services. Each of these segments operates within the Company’s single Washington, D.C. reportable geographic segment.

	Depreciation and amortization		686			—			—		686
	Interest expense		73			—			—		73
	The Company allocates sales, marketing and general and administrative expenses to the individual segments based upon specifically allocable costs and, in the absence of direct allocations, based upon its estimate of time allocable to the segment or based upon overall pro rata revenue generation.
Use of estimates	Use of estimates
	The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts in the financial statements and accompanying notes. Actual results could differ from those estimates. Material estimates are utilized in the valuation of real estate inventories, valuation of deferred tax assets, capitalization of costs, consolidation of variable interest entities and warranty reserves.
Out of Period Adjustment	Out of Period Adjustment
	During the fourth quarter of 2014 the Company recorded an out-of-period adjustment resulting in a $177 decrease to ‘General and administrative’ expense within the consolidated statements of operations. Because this error was not material to any previously filed consolidated financial statements and the impact of correcting this error in the current period is not material to our 2014 consolidated financial statements, the Company recorded the correction of this error in the fourth quarter of 2014, the period in which the error was identified.
Reclassifications	Reclassifications
	Certain amounts in the prior year financial statements have been reclassified to conform to the current-year presentation. The impact of the reclassifications made to prior year amounts is not material and did not affect net loss.
Recent accounting pronouncements	Recent accounting pronouncements
	In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, (“ASU 2014-09”). ASU 2014-09 provides a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. ASU No. 2014-09 will require an entity to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This update creates a five-step model that requires entities to exercise judgment when considering the terms of the contract(s) which include (i) identifying the contract(s) with the customer, (ii) identifying the separate performance obligations in the contract, (iii) determining the transaction price, (iv) allocating the transaction price to the separate performance obligations, and (v) recognizing revenue when each performance obligation is satisfied. ASU 2014-09 will be effective for fiscal year beginning after December 1, 2017 and subsequent interim periods. The Company has the option to apply the provisions of ASU 2014-09 either retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of applying this ASU recognized at the date of initial application. Early adoption is not permitted. The Company is currently evaluating the method and impact the adoption of ASU 2014-09 will have on the Company’s consolidated financial statements.
	Other accounting pronouncements issued or effective during the year ended December 31, 2014 are not applicable to us and are not anticipated to have an effect on our consolidated financial statements.
Consolidation Of Entities	The Company does not share in an allocation of either the profit earned or loss incurred by any of these entities with which the Company has fixed price purchase agreements. The Company has concluded that whenever it options land or lots from an entity and pays a significant non-refundable deposit as described above, a variable interest entity is created under the provisions of ASC 810-10, Consolidation. This is because the Company has been deemed to have provided subordinated financial support, which creates a variable interest which limits the equity holder’s returns and may absorb some or all of an entity’s expected theoretical losses if they occur. The Company, therefore, examines the entities with which it has fixed price purchase agreements for possible consolidation by the Company under the provision of ASC 810-10.
Fair Value Measurements	ASC 820 establishes a framework for measuring fair value, expands disclosures regarding fair value measurements and defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC 820 specifies a hierarchy of valuation techniques based on whether the inputs to a fair value measurement are considered to be observable or unobservable in a marketplace.
