Summary of Significant Accounting Policies [Abstract]	'
Significant Accounting Policies [Text Block]	'
	Summary of Significant Accounting Policies
	Business and Principles of Consolidation.  Stratus Properties Inc. (Stratus), a Delaware corporation, is engaged in the acquisition, development, management, operation and sale of commercial, hotel, entertainment, and multi- and single-family residential real estate properties located primarily in the Austin, Texas area. The real estate development and marketing operations of Stratus are conducted through its wholly owned subsidiaries, two consolidated joint ventures (see Notes 2 and 3) and through unconsolidated joint ventures (see “Investments in Unconsolidated Affiliates” below and Note 6). Stratus consolidates its wholly owned subsidiaries, subsidiaries in which Stratus has a controlling interest and variable interest entities in which Stratus is deemed the primary beneficiary. All significant intercompany transactions have been eliminated in consolidation.
	On February 27, 2012, Stratus sold its two office buildings at 7500 Rialto Boulevard (7500 Rialto). As a result, 7500 Rialto is reported as discontinued operations (see Note 12).
	Concentration of Risks.  Stratus primarily conducts its operations in Austin, Texas. Consequently, any significant economic downturn in the Austin market could potentially have an effect on Stratus’ business, results of operations and financial condition.
	Use of Estimates.  The preparation of financial statements in conformity with accounting principles generally accepted in the United States (U.S.) requires management to make estimates and assumptions that affect the amounts reported in these financial statements and accompanying notes. The more significant estimates include the (1) estimates of future cash flow from development and sale of real estate properties used in the assessment of impairments, (2) valuation allowances for deferred tax assets, (3) allocation of certain indirect costs and (4) useful lives for depreciation. Actual results could differ from those estimates.
	Real Estate and Commercial Leasing Assets.  Real estate held for sale is stated at the lower of cost or fair value less costs to sell. The cost of real estate held for sale includes acquisition, development, construction and carrying costs, and other related costs through the development stage. Real estate under development and land available for development are stated at cost. Real estate held for investment, which includes the hotel and entertainment venue at the W Austin Hotel & Residences project and Stratus' commercial leasing assets, is stated at cost, less accumulated depreciation. Stratus capitalizes interest on funds used in developing properties from the date of initiation of development activities through the date the property is substantially complete and ready for sale or lease. Common costs are allocated based on the relative fair value of individual land parcels. Certain carrying costs are capitalized on properties currently under active development. Stratus capitalizes improvements that increase the value of commercial leasing properties and have useful lives greater than one year. Costs related to repairs and maintenance are charged to expense as incurred.
	Stratus performs an impairment test when events or circumstances indicate that an asset’s carrying amount may not be recoverable. Events or circumstances that Stratus considers indicators of impairment include significant decreases in market values, adverse changes in regulatory requirements (including environmental laws), significant budget overruns for properties under development, and current period or projected operating cash flow losses from rental properties. Impairment tests for properties to be held and used, including properties under development, involve the use of estimated future net undiscounted cash flows expected to be generated from the use of the property and its eventual disposition. If projected undiscounted cash flow from properties to be held and used is less than the related carrying amount, then a reduction of the carrying amount of the long-lived asset to fair value is required. Measurement of the impairment loss is based on the fair value of the asset. Generally, Stratus determines fair value using valuation techniques such as discounted expected future cash flows. Impairment tests for properties held for sale involve management estimates of fair value based on estimated market values for similar properties in similar locations and management estimates of costs to sell. If estimated fair value less costs to sell is less than the related carrying amount, then a reduction of the carrying amount of the asset to fair value less costs to sell is required.
	Stratus recorded no impairment charges for the years ended December 31, 2013 and 2012. Should market conditions deteriorate in the future or other events occur that indicate the carrying amount of Stratus’ real estate assets may not be recoverable, Stratus will reevaluate the expected cash flows from each property to determine whether any impairment exists.
	Depreciation.  Commercial leasing properties are depreciated on a straight-line basis over their estimated life of between 30 and 40 years. The hotel and entertainment venue properties are depreciated on a straight-line basis over their estimated life of 35 years. Furniture, fixtures and equipment are depreciated on a straight-line basis over a three to five-year period. Tenant improvements are depreciated over the related lease terms.
	Investments in Unconsolidated Affiliates.  Stratus has interests in three unconsolidated affiliates, which it accounts for under the equity method (see Note 6).
	Other Assets.  Other assets primarily consist of restricted cash, deferred financing and leasing costs, prepaid insurance, tenant and other accounts receivable, and notes and interest receivable. Deferred financing costs are amortized using the straight-line method over the term of the related debt, which approximates the effective interest method, to interest expense. Deferred leasing costs are amortized to cost of sales using the straight-line method over the related lease terms.
	Accrued Property Taxes.  Stratus estimates its property taxes based on prior year property tax payments and other current events that may impact the amount. Upon receipt of the property tax bill, Stratus adjusts its accrued property tax balance at year-end to the actual amount of taxes due in January. Accrued property taxes totaled $5.1 million at December 31, 2013, and $5.2 million at December 31, 2012.
	Revenue Recognition.  Revenues from property sales are recognized when the risks and rewards of ownership are transferred to the buyer, when the consideration received can be reasonably determined and when Stratus has completed its obligations to perform certain supplementary development activities, if any exist, at the time of the sale. Consideration is reasonably determined and considered likely of collection when Stratus has signed sales agreements and has determined that the buyer has demonstrated a commitment to pay. The buyer’s commitment to pay is supported by the level of their initial investment, Stratus’ assessment of the buyer’s credit standing and Stratus’ assessment of whether the buyer’s stake in the property is sufficient to motivate the buyer to honor their obligation to pay.
	Stratus' revenues from hotel operations are primarily derived from room reservations and food and beverage sales. Revenue is recognized when rooms are occupied and services have been rendered. Taxes collected from customers and submitted to taxing authorities are not recorded in revenue.
	Stratus' revenues from entertainment operations are primarily derived from ticket sales; sponsorships, personal seat licenses and suite sales; and sales of concessions and merchandise. Revenues from ticket sales are recognized after the corresponding performance occurs. Revenues from sponsorships and other revenue not related to a single event are classified as deferred revenue and generally amortized over the operating season or term of the contract. Revenues from concessions and merchandise sales are recognized at the time of sale.
	Stratus recognizes its rental income based on the terms of its signed leases with tenants on a straight-line basis. Recoveries from tenants for taxes, insurance and other commercial property operating expenses are recognized as revenues in the period the related costs are incurred. Stratus recognizes sales commissions and management and development fees when earned, as properties are sold or when the services are performed.
	A summary of Stratus’ revenues follows (in thousands):
		Years Ended December 31,
		2013				2012
	Revenues:
	Developed property sales	$	63,676			$	45,716
	Undeveloped property sales	3,266				15,837
	Hotel	39,234				35,402
	Entertainment	15,481				13,799
	Rental	5,406				4,422
	Commissions and other	647				561
	Total revenues	$	127,710			$	115,737
	Cost of Sales.  Cost of sales includes the cost of real estate sold as well as costs directly attributable to the properties sold such as marketing, maintenance and property taxes. Cost of sales also includes operating costs and depreciation for properties held for investment and municipal utility district reimbursements. A summary of Stratus’ cost of sales follows (in thousands):
		Years Ended December 31,
		2013				2012
	Cost of developed property sales	$	48,732			$	38,364
	Cost of undeveloped property sales	1,122				11,539
	Hotel	29,483				26,883
	Entertainment	12,922				12,086
	Rental	2,670				2,165
	Project expenses and allocation of overhead costs (see below)	5,423				6,477
	Municipal utility district reimbursements (see below)	—				(688		)
	Depreciation	9,053				9,165
	Other, net	(1,148		)	a	433
	Total cost of sales	$	108,257			$	106,424
	a. Includes a credit of $1.1 million related to the recovery of building repair costs associated with damage caused by the June 2011 balcony glass breakage incidents at the W Austin Hotel & Residences project.
	Gross profit on condominium sales from the W Austin Hotel & Residences project is based on estimates of total project sales value and total project costs for the condominiums. When estimates of sales value or project costs are revised, gross profit is adjusted in the period of change so that cumulative project earnings reflect the revised profit estimate. Stratus revised estimates of projected aggregate profit margins on condominium units at the W Austin Hotel & Residences project, resulting in a charge to cost of sales totaling $1.5 million in 2012.
	Allocation of Overhead Costs.  Stratus has historically allocated a portion of its overhead costs to both capitalized real estate costs and cost of sales based on the percentage of time certain of its employees, comprising its indirect overhead pool, worked in the related areas (i.e. construction and development for capital assets and sales and marketing for cost of sales). Stratus capitalizes only direct and certain indirect project costs associated with the acquisition, development and construction of a real estate project. Indirect costs include allocated costs associated with certain pooled resources (such as office supplies, telephone and postage) which are used to support Stratus’ development projects, as well as general and administrative functions. Allocations of pooled resources are based only on those employees directly responsible for development (i.e., project managers and subordinates). Stratus charges to expense indirect costs that do not clearly relate to a real estate project, such as salaries and costs related to its Chief Executive Officer and Chief Financial Officer.
	Municipal Utility District Reimbursements.  Stratus receives Barton Creek Municipal Utility District (MUD) reimbursements for certain infrastructure costs incurred in the Barton Creek area. Prior to 1996, Stratus capitalized infrastructure costs to its properties as those costs were incurred. Subsequently, those costs were charged to cost of sales as properties were sold. In 1996, following the 1995 creation of MUDs, Stratus began capitalizing the infrastructure costs to a separate MUD property category. MUD reimbursements received for infrastructure costs incurred prior to 1996 are reflected as a reduction of cost of sales, while other MUD reimbursements represent a reimbursement of the cost of MUD properties and are recorded as a reduction of the related asset’s carrying amount or cost of sales if the property has been sold. Stratus has long-term agreements with seven independent MUDs in Barton Creek to build the MUDs’ utility systems and to be eligible for future reimbursements for the related costs. The amount and timing of MUD reimbursements depends upon the respective MUD having a sufficient tax base within its district to issue bonds and obtaining the necessary state approval for the sale of the bonds. Because the timing of the issuance and approval of the bonds is subject to considerable uncertainty, coupled with the fact that interest rates on such bonds cannot be fixed until they are approved, the amounts associated with MUD reimbursements are not known until approximately one month before the MUD reimbursements are received. To the extent the reimbursements are less than the costs capitalized, Stratus records a loss when that determination is made. MUD reimbursements represent the actual amounts received.
	Advertising Costs.  Advertising costs are expensed as incurred and are included as a component of cost of sales. Advertising costs totaled $0.9 million in 2013 and $0.6 million in 2012.
	Income Taxes.  Stratus accounts for deferred income taxes utilizing an asset and liability method, whereby deferred tax assets and liabilities are recognized based on the tax effects of temporary differences between the financial statements and the tax basis of assets and liabilities, as measured by current enacted tax rates. The effect on deferred income tax assets and liabilities of a change in tax rates or laws is recognized in income in the period in which such changes are enacted. Stratus periodically evaluates the need for a valuation allowance to reduce deferred tax assets to estimated recoverable amounts. Stratus establishes a valuation allowance to reduce its deferred tax assets and records a corresponding charge to earnings if it is determined, based on available evidence at the time, that it is more likely than not that any portion of the deferred tax assets will not be realized. In evaluating the need for a valuation allowance, Stratus estimates future taxable income based on projections and ongoing tax strategies. This process involves significant management judgment about assumptions that are subject to change based on variances between projected and actual operating performance and changes in Stratus’ business environment or operating or financial plans. See Note 8 for further discussion.
	Earnings Per Share.  Stratus’ basic net income per share of common stock was calculated by dividing the net income (loss) attributable to Stratus common stock by the weighted-average shares of common stock outstanding during the period. A reconciliation of net income (loss) and weighted-average shares of common stock outstanding for purposes of calculating diluted net income (loss) per share (in thousands, except per share amounts) for the years ended December 31 follows:
		2013				2012
	Net income (loss)	$	5,894			$	(4,313	)
	Net (income) loss attributable to noncontrolling interests	(3,309		)		2,727
	Net income (loss) attributable to Stratus common stock	$	2,585			$	(1,586	)
	Weighted-average shares of Stratus common stock outstanding	8,077				7,966
	Add shares issuable upon exercise or vesting of:
	Dilutive stock options	7			a	—
	Restricted stock units	27				—
	Weighted-average shares of Stratus common stock outstanding for purposes of calculating diluted net income (loss) per share	8,111				7,966
	Diluted net income (loss) per share attributable to Stratus common stock	$	0.32			$	(0.20	)
	a. Excludes shares of Stratus common stock associated with outstanding stock options with exercise prices less than the average market price of Stratus' common stock that were anti-dilutive based on the treasury stock method totaling approximately 1,250 shares for the year ended December 31, 2013.
	Outstanding stock options with exercise prices greater than the average market price for Stratus' common stock during the period are excluded from the computation of diluted net income (loss) per share of common stock. Excluded were approximately 63,500 stock options with a weighted average exercise price of $20.85 for 2013. Stock options and restricted stock units representing approximately 134,300 shares for 2012 were excluded from weighted-average common shares outstanding for purposes of calculating diluted net income (loss) per share because they were anti-dilutive, either because inclusion of the options would result in a decrease of Stratus' net loss per share, or the stock options had exercise prices greater than the average market price of Stratus' common stock.
	Stock-Based Compensation.  Compensation costs for share-based payments to employees, including stock options, are measured at fair value and charged to expense over the requisite service period for awards that are expected to vest. The fair value of stock options is determined using the Black-Scholes option valuation model. In addition, for restricted stock units, compensation costs are recognized based on the fair value on the date of grant. Stratus estimates forfeitures at the time of grant and revises those estimates in subsequent periods if actual forfeitures differ from those estimates through the final vesting date of the awards. See Note 9 for further discussion.

	Joint Venture with Canyon-Johnson Urban Fund II, L.P.
	Stratus and Canyon-Johnson Urban Fund II, L.P. (Canyon-Johnson) are participants in a joint venture, CJUF II Stratus Block 21, LLC, for a 36-story mixed-use development in downtown Austin, Texas, anchored by a W Hotel & Residences (the W Austin Hotel & Residences project). Stratus is the manager of, and has an approximate 40 percent interest in, the joint venture, and Canyon-Johnson has an approximate 60 percent interest in the joint venture. As of December 31, 2013, cumulative capital contributions totaled $71.9 million for Stratus and $94.0 million for Canyon-Johnson. As of December 31, 2013, cumulative distributions to Stratus totaled $44.7 million, including $34.8 million in 2013, and $50.6 million to Canyon-Johnson, including $40.7 million in 2013.
	Upon formation of the joint venture, Stratus performed an initial evaluation and concluded that the joint venture was a variable interest entity (VIE) and that Stratus was the primary beneficiary. Stratus reevaluated and reaffirmed its previous conclusion as to the VIE status and primary beneficiary of the joint venture with Canyon-Johnson as of September 30, 2013, the date of the Bank of America (BoA) refinancing transaction (see Note 7). Stratus will continue to evaluate which entity is the primary beneficiary of the joint venture in accordance with applicable accounting guidance.
	Stratus’ consolidated balance sheets include the following assets and liabilities of the joint venture (in thousands):
		December 31,		December 31,

	Total liabilities	114,799		91,684
	Net assets	$	79,576	$	150,818
	Profits and losses between partners in a real estate venture should be allocated based on how changes in net assets of the venture would affect cash payments to the investors over the life of the venture and on its liquidation. The amount of the ultimate profits earned by the W Austin Hotel & Residences project will affect the ultimate profit sharing ratios because of provisions in the joint venture agreement which would require Stratus to return certain previously received distributions to Canyon-Johnson under certain circumstances. Because of the uncertainty of the ultimate profits and, therefore, profit-sharing ratios, the W Austin Hotel & Residences project's cumulative profits or losses are allocated based on a hypothetical liquidation of the joint venture's net assets as of each balance sheet date. At December 31, 2013, the cumulative income for the W Austin Hotel & Residences project was allocated based on 42 percent for Stratus and 58 percent for Canyon-Johnson.
	On October 3, 2012, the joint venture and Pedernales Entertainment LLC (Pedernales) formed Stageside Productions (Stageside) to promote, market and commercialize the production, sale, distribution and general oversight of audio and video recordings of events or performances occurring at Austin City Limits Live at the Moody Theater (ACL Live). The joint venture's initial capital contributions to Stageside totaled $0.3 million, and the joint venture will contribute additional capital as necessary to fund the working capital needs of Stageside. The joint venture has a 100 percent capital funding interest and has a 40 percent residual and voting interest in Stageside. The joint venture performed an evaluation and concluded Stageside is a VIE and that the joint venture is the primary beneficiary. Accordingly, the results of Stageside are consolidated in the joint venture's financial statements.

	Fair Value Measurements
	Fair value accounting guidance includes a hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 inputs) and the lowest priority to unobservable inputs (Level 3 inputs).
	The carrying value for certain Stratus financial instruments (i.e., cash, restricted cash, accounts and notes receivable, accounts payable and accrued liabilities) approximate fair value because of their short-term nature and generally negligible credit losses. A summary of the carrying amount and fair value of Stratus' other financial instruments follows (in thousands):
		December 31, 2013				December 31, 2012
		Carrying		Fair		Carrying		Fair
		Value		Value		Value		Value

	Interest rate cap agreement	$	351	$	351	$	—	$	—
	Liabilities:
	Interest rate swap	32		32		—		—
	Debt	151,332		151,584		137,035		136,774
	Interest Rate Cap Agreement. On September 30, 2013, the joint venture with Canyon-Johnson paid $0.5 million to enter into an interest rate cap agreement, which caps the one-month London Interbank Offered Rate (LIBOR), the variable rate in the BoA loan agreement, at 1 percent for the first year the BoA loan is outstanding, 1.5 percent for the second year and 2 percent for the third year. Stratus uses an interest rate pricing model that relies on market observable inputs such as LIBOR to measure the fair value of the interest rate cap agreement. Stratus also evaluated the counterparty credit risk associated with the interest rate cap agreement, which is considered a Level 3 input, but did not consider such risk to be significant. Therefore, the interest rate cap agreement is classified within Level 2 of the fair value hierarchy. See Note 7 for more information on the BoA loan.
	Interest Rate Swap Agreement. On December 13, 2013, the joint venture with Moffett Holdings entered into an interest rate swap agreement with Comerica Bank that effectively converts the Parkside Village loan's variable rate from one-month LIBOR to a fixed rate of 2.3 percent. With the swap agreement in place, the joint ventures' interest cost on the Parkside Village loan will be 4.8 percent through the December 31, 2020, maturity date. Stratus also evaluated the counterparty credit risk associated with the interest rate swap agreement, which is considered a Level 3 input, but did not consider such risk to be significant. Therefore, the interest rate swap agreement is classified within Level 2 of the fair value hierarchy. See Note 7 for more information on the Parkside Village loan.
	Debt. Stratus' debt is recorded at cost and is not actively traded. Fair value is estimated based on discounted future expected cash flows at estimated current market interest rates. Accordingly, Stratus' debt is classified within Level 2 of the fair value hierarchy. The fair value of debt does not represent the amounts that will ultimately be paid upon the maturities of the loans.

	Investment in Unconsolidated Affiliates
	Crestview Station. In 2005, Stratus formed a joint venture with Trammell Crow Central Texas Development, Inc. (Trammell Crow) to acquire an approximate 74-acre tract at the intersection of Airport Boulevard and Lamar Boulevard in Austin, Texas, for $7.7 million. The property, known as Crestview Station, is a single- and multi-family, retail and office development, which is located on a commuter rail line. With Trammell Crow, Stratus completed environmental remediation, which the State of Texas certified as complete in September 2007, and permitting of the property. Crestview Station sold substantially all of its multi-family residential and commercial properties in 2007 and one commercial site in 2008.
	During 2012, Crestview Station entered into an agreement to sell the remaining residential land to DR Horton. The contract provides for the sale of 304 lots over four years for a total contract price of $15.8 million. The first closing of 73 lots for $3.8 million occurred in April 2012, and Crestview Station recognized gross profit on the sale of $0.4 million. The second closing of 59 lots for $3.4 million occurred in May 2013, and Crestview Station recognized gross profit on the sale of $0.7 million. At December 31, 2013, Stratus' investment in Crestview Station totaled $3.6 million and Crestview Station had $0.9 million of outstanding debt, for which Stratus and Trammell Crow have executed a joint and several guaranty of $0.2 million, or 25 percent of the outstanding balance. The loan was repaid subsequent to December 31, 2013, in connection with the third closing of 59 lots in March 2014. Stratus accounts for its 50 percent interest in the Crestview Station joint venture under the equity method.
	Stump Fluff. In April 2013, Stratus formed a joint venture, Stump Fluff LLC (Stump Fluff), with Transmission Entertainment, LLC (Transmission) to own, operate, manage and sell live music and entertainment promotion, booking, production, merchandising, venue services and other related products and services. As of December 31, 2013, Stratus' capital contributions to Stump Fluff totaled $0.8 million. Stratus will contribute additional capital to Stump Fluff as necessary to fund its working capital needs. Transmission contributed its existing assets to Stump Fluff. In addition, Stump Fluff assumed specified liabilities of Transmission totaling $0.2 million. Transmission is not required to make any future capital contributions to Stump Fluff. Stratus and Transmission each have a 50 percent voting interest in Stump Fluff. After Stratus is repaid its original capital contributions and a preferred return (10 percent annually) on those contributions, Stratus will receive 33 percent of any distributions from Stump Fluff and Transmission will receive 67 percent.
	Guapo Enterprises. In May 2013, Stratus and Austin Pachanga Partners, LLC (Pachanga Partners) formed a joint venture, Guapo Enterprises LLC (Guapo) to own, operate, manage and sell the products and services of the Pachanga music festival business. As of December 31, 2013, Stratus' capital contributions to Guapo totaled $0.3 million. Stratus will contribute additional capital to Guapo as necessary to fund its working capital needs. Pachanga Partners contributed its existing assets to Guapo and is not required to make any future capital contributions. Stratus and Pachanga Partners each have a 50 percent voting interest in Guapo. After Stratus is repaid its original capital contributions and a preferred return (10 percent annually) on those contributions, Stratus will receive 33 percent of any distributions from Guapo and Pachanga Partners will receive 67 percent.
	Stratus has concluded that both Stump Fluff and Guapo are VIEs and that no partner in either joint venture is the primary beneficiary because decision-making about the activities that most significantly impact the VIEs' economic performance is shared equally by the partners. Stratus accounts for its investments in Stump Fluff and Guapo using the equity method.
	Stratus’ equity in unconsolidated affiliates' losses totaled $76 thousand in 2013 and less than $29 thousand in 2012. Summarized unaudited financial information for Stratus' unconsolidated affiliates follows (in thousands):

	Bank of America Loan. On September 30, 2013, the joint venture with Canyon-Johnson entered into a term loan agreement for a $100 million non-recourse loan.
	The initial maturity date of the BoA loan is September 29, 2016, but the joint venture has the option to extend the maturity date for up to three additional one-year terms. The BoA loan accrues interest at the LIBOR daily floating rate plus 2.5 percent. The joint venture entered into an interest rate cap agreement for the BOA loan (see Note 5). The joint venture’s obligations under the BoA loan are secured by certain property and assets related to the W Austin Hotel & Residences project, excluding the remaining unsold condominium residences. Additionally, Stratus and Canyon-Johnson guarantee certain obligations of the joint venture, including environmental indemnification and other customary carve-out obligations. The BoA loan contains customary financial covenants and other restrictions. As required by the BoA loan, $67.3 million of the proceeds were used to fully repay the joint venture’s existing obligations to Beal Bank USA (Beal Bank). Stratus also used a portion of its distribution from the BOA loan to repay the $11.7 million balance outstanding under its revolving line of credit with Comerica Bank.
	Unsecured Term Loans. Stratus has $23.0 million outstanding under five unsecured term loans with American Strategic Income Portfolio Inc. (ASIP, formerly First American Asset Management, or FAAM), including two $3.5 million loans, an $8.0 million loan, a $5.0 million loan and a $3.0 million loan.
	In September 2012, Stratus extended and modified the ASIP loans effective as of September 1, 2012, and paid in full the outstanding balance of $2.0 million on one of the unsecured term loans that was scheduled to mature on December 31, 2012, and the $7.0 million unsecured term loans that were scheduled to mature on June 30, 2013. The ASIP loan modifications reduced the interest rate from 8.75 percent to 7.25 percent, and extended the maturity dates as follows:
	Lender		Principal Balance		Former		Modified Maturity Date
					Maturity Date
	American Strategic Income Portfolio Inc.-II		$	3,000,000	12/31/12		12/31/15

	American Strategic Income Portfolio Inc.			3,500,000	12/31/14		3/31/15
	All other terms and conditions under each of the unsecured term loans remained unchanged, including the debt service coverage ratio covenant and the alternative covenant that requires Stratus to maintain total stockholders' equity of no less than $120.0 million. On May 9, 2013, Stratus entered into a modification agreement with ASIP that reduced the amount of total stockholders' equity required to be maintained by Stratus from $120.0 million to $110.0 million. Concurrently with this modification, the minimum stockholders' equity covenant of the Comerica credit facility was also reduced to $110.0 million. See below for more information on the Comerica credit facility.
	Parkside Village Loan. On May 17, 2011, the joint venture entered into a construction loan agreement and promissory note with Comerica Bank to finance the development of Parkside Village. In December 2013, the joint venture between Stratus and Moffett Holdings extended and modified the Parkside Village loan, effective as of December 12, 2013. The Parkside Village loan modifications extended the maturity date from December 31, 2013, to December 31, 2020, increased the principal amount available to a total of $19.7 million, replaced the debt coverage provision by providing for a minimum debt yield, as defined in the agreement, of 9.1 percent, and amended certain other provisions of the agreement. As of December 31, 2013, the amount outstanding was $17.7 million with $2.0 million available.
	The loan is secured by a lien on the assets of the Parkside Village project, which had a net book value of $15.8 million at December 31, 2013, and Stratus has provided a limited guaranty.
	Slaughter Term Loan. Stratus has $5.1 million outstanding under a $5.4 million term loan, which will mature on January 31, 2015. The loan is secured by 5700 Slaughter, which had a net book value of $4.7 million at December 31, 2013. The interest rate is 6.95 percent, and payments of principal and interest are due monthly.
	Barton Creek Village Term Loan. Stratus has $4.3 million outstanding under a term loan, which will mature on April 1, 2014. The loan is secured by Barton Creek Village, which had a net book value of $5.0 million at December 31, 2013. The interest rate is 6.25 percent, and payments of interest and principal are due monthly.
	Lakeway Land Term Loan. On May 15, 2013, Stratus entered into a loan agreement and promissory note with D.N. Kahn to finance the purchase of a tract of land for future development in Lakeway, Texas (the Lakeway land term loan). Stratus has $1.6 million outstanding under the loan, which will mature on May 15, 2015. The loan is secured by the related land, which had a net book value of $2.3 million at December 31, 2013. The interest rate is 5 percent, with payments due quarterly.
	Beal Bank Loan.  On October 21, 2009, the joint venture with Canyon-Johnson obtained construction financing from Beal Bank for up to an aggregate of $120.0 million to fund the construction, development and marketing costs of the W Austin Hotel & Residences project. In third-quarter 2013, the joint venture fully repaid the Beal Bank loan. In connection with the repayment of the loan, the joint venture paid a prepayment premium equal to 1 percent of the outstanding principal balance, which was recorded as a loss on early extinguishment of debt in the Statements of Operations.
	Comerica Credit Facility. Effective December 31, 2012, Stratus amended its credit facility, such that the existing $45.0 million facility was replaced with a $48.0 million credit facility, divided into three tranches as follows: (1) a $35.0 million revolving line of credit, (2) $3.0 million for letters of credit and (3) a $10.0 million construction loan. The interest rate applicable to amounts borrowed under each loan is an annual rate of LIBOR plus 4.0 percent, with a minimum interest rate of 6.0 percent. The credit facility will mature on November 30, 2014. Stratus' obligations under the credit facility are secured by substantially all of Stratus' assets, except for properties that are encumbered by separate non-recourse permanent loan financing, and sets limitations on liens and transactions with affiliates and requires that certain financial ratios be maintained, including a requirement that Stratus maintain a minimum total stockholders' equity balance of $110.0 million.
	Under the terms of the credit facility, (1) any distributions received by Stratus from its investment in the W Austin Hotel & Residences project shall be paid to Comerica and applied against the $35.0 million revolving loan to the extent of any outstanding debt and (2) MUD reimbursements and land sales proceeds directly related to Section N of Barton Creek shall be used to first repay the Barton Creek Village term loan (discussed above), with any excess used to pay down the $35.0 million revolving loan. Any amounts borrowed and repaid under the $10.0 million construction loan will not be available for future advance to Stratus. At December 31, 2013, no amounts were outstanding under the revolving line of credit, letters of credit tranche or the construction loan.
	Maturities. The following table summarizes Stratus' debt maturities as of December 31, 2013 (in thousands):

	Stratus’ deferred tax assets (net of deferred tax liabilities) before any valuation allowances totaled $12.4 million at December 31, 2013, and $13.8 million at December 31, 2012. In evaluating the recoverability of these deferred tax assets, Stratus considered available positive and negative evidence, giving greater weight to the recent losses, the absence of taxable income in the carry back period and uncertainty regarding projected future financial results. As a result, Stratus concluded that there was not sufficient positive evidence supporting the realizability of its deferred tax assets beyond an amount totaling $0.3 million at each of December 31, 2013, and December 31, 2012, and Stratus recorded credits totaling $1.4 million in 2013 and charges totaling $0.5 million in 2012 to the provision for income taxes to adjust the valuation allowances.
	Stratus’ future results of operations may be negatively impacted by its inability to realize a tax benefit for future tax losses or for items that will generate additional deferred tax assets that are not more likely than not to be realized. Stratus’ future results of operations may be favorably impacted by reversals of valuation allowances if Stratus is able to demonstrate sufficient positive evidence that its deferred tax assets will be realized.
	Stratus’ income tax provision consists of the following (in thousands):
		Years Ended December 31,
		2013			2012
	Current	$	(899	)	$	(778	)
	Deferred	(30		)	142
	Provision for income taxes	$	(929	)	$	(636	)
	Excess tax benefits related to option exercises and vesting of restricted stock units cannot be recognized until realized through a reduction of current taxes payable. Stratus' deferred tax asset related to the U.S. net operating loss carry forwards at December 31, 2013, did not include an additional $5.0 million of net operating losses in relation to excess tax benefits on stock option exercises and restricted stock units vested beginning in 2007 because these benefits have not yet been realized. At December 31, 2013, excluding these losses, Stratus had net operating loss carryforwards of approximately $1.9 million that expire between 2028 and 2031.
	During 2013 and 2012, Stratus recorded unrecognized tax benefits related to state income tax filing positions. A summary of the changes in unrecognized tax benefits follows (in thousands):
		December 31,
		2013			2012
	Balance at January 1	$	562		$	—
	Additions for tax positions related to the current year	274			252
	Additions for tax positions related to prior years	18			310
	Balance at December 31	$	854		$	562
	As of December 31, 2013, there was $0.9 million of unrecognized tax benefits that if recognized would affect Stratus' annual effective tax rate. Stratus does not expect its unrecognized tax benefits to change significantly over the next 12 months.
	Stratus records liabilities offsetting the tax provision benefits of uncertain tax positions to the extent it estimates that a tax position is not more likely than not to be sustained upon examination by the taxing authorities. Stratus has elected to classify any interest expense and penalties related to income taxes within income tax expense in its consolidated statements of operations. As of December 31, 2013, less than $0.1 million of interest costs have been accrued.
	Stratus files income tax returns in the U.S. federal jurisdiction and state jurisdictions. With few exceptions, Stratus is no longer subject to U.S. federal income tax examinations by tax authorities for the years prior to 2009, and state income tax examinations for the years prior to 2008.

	Stock-Based Compensation, Equity Transactions and Employee Benefits
	Stock-Based Compensation Plans.  Stratus currently has three stock-based compensation plans, all of which have awards available for grant. In May 2013, Stratus' shareholders approved the 2013 Stock Incentive Plan, which provides for the issuance of stock-based compensation awards, including stock options and restricted stock units, relating to 180,000 shares of Stratus common stock that are issuable to Stratus employees and non-employee directors. Stratus’ 2010 Stock Incentive Plan provides for the issuance of stock options and restricted stock units relating to 140,000 shares of Stratus common stock that are issuable to Stratus employees and non-employee directors. Stratus’ 1996 Stock Option Plan for Non-Employee Directors provides for the issuance of stock options only. Stratus common stock issued upon option exercises or restricted stock unit vestings represent newly issued shares of common stock. Awards with respect to 180,000 shares under the 2013 Stock Incentive Plan, 8,875 shares under the 2010 Stock Incentive Plan and 2,500 shares under the 1996 Stock Option Plan for Non-Employee Directors were available for new grants as of December 31, 2013.
	Stock-Based Compensation Costs.  Compensation costs charged against earnings for stock-based awards are shown below (in thousands). Stock-based compensation costs are capitalized when appropriate. Stratus’ estimated forfeiture rate used in estimating stock-based compensation costs for stock options was 2.8 percent and for restricted stock units was zero percent for the years presented below.
		Years Ended December 31,
		2013			2012
	Stock options awarded to employees (including directors)	$	14		$	28
	Restricted stock units awarded to employees	324			241
	Impact on net income (loss) before income taxes	$	338		$	269
	Options.  Stock options granted under the plans generally expire 10 years after the date of grant and vest in 25 percent annual increments beginning one year from the date of grant. The plans and award agreements provide that participants will receive the following year’s vesting after retirement and provide for accelerated vesting if there is a change of control (as defined in the plans). A summary of stock options outstanding as of December 31, 2013, and changes during the year ended December 31, 2013, follows:
		Number of		Weighted			Weighted	Aggregate

	Forfeited	(3,750	)	9
	Balance at December 31	92,000		17.45
	The fair value of each option award is estimated on the date of grant using a Black-Scholes option valuation model. Expected volatility is based on the historical volatility of Stratus’ common stock. Stratus estimates its expected life of options using historical data to estimate option exercises and forfeitures. When appropriate, employees who have similar historical exercise behavior are grouped for valuation purposes. The risk-free interest rate is based on Federal Reserve rates in effect for bonds with maturity dates equal to the expected term of the option at the date of grant. Stratus has not paid, and has no current plan to pay, cash dividends on its common stock. There were no stock options granted during 2013 or 2012.
	The intrinsic value of options exercised during 2013 and 2012 was less than $0.1 million. Vested stock options totaled 3,750 during 2013 and 7,500 during 2012 with weighted-average grant-date fair values of $5.91 per option and $8.30 per option, respectively. As of December 31, 2013, there were 3,750 stock options unvested with a weighted-average grant-date fair value of $6.72 per option. As of December 31, 2013, Stratus had less than $10,000 of total unrecognized compensation cost related to unvested stock options expected to be recognized over a weighted average period of less than one year.
	The following table includes amounts related to exercises of stock options and vesting of restricted stock units for the years ended December 31, 2013, and 2012 (in thousands, except shares of Stratus common stock tendered):
		2013			2012

	Cash received from stock option exercises	$	91		$	43
	Amounts Stratus paid for employee taxes	$	9		$	2
	a.	Under terms of the related plans, upon exercise of stock options and vesting of restricted stock units, employees may tender shares of Stratus common stock to Stratus to pay the exercise price and/or the minimum required taxes.
	Restricted Stock Units.  Restricted stock units granted under the plans provide for the issuance of common stock to the non-employee directors and certain officers of Stratus at no cost to the directors and officers. The restricted stock units are converted into shares of Stratus common stock ratably and generally vest in one-quarter increments over the four years following the grant date. For officers, the awards will fully vest upon retirement, death and disability, and upon a change of control. For directors, the awards will fully vest upon a change of control and there will be a partial acceleration of vesting due to retirement, death and disability.
	A summary of outstanding unvested restricted stock units as of December 31, 2013, and activity during the year ended December 31, 2013, is presented below:
		Number of		Aggregate
		Restricted		Intrinsic
		Stock Units		Value
				$0

	Granted	48,000
	Vested	(30,125	)
	Balance at December 31	100,875		$	1,728
	The total grant date fair value of restricted stock units granted during the year ended December 31, 2013, was $0.6 million. The total intrinsic value of restricted stock units vesting during the year ended December 31, 2013, was $0.4 million. As of December 31, 2013, Stratus had $0.8 million of total unrecognized compensation cost related to unvested restricted stock units expected to be recognized over a weighted-average period of 1.8 years.
	Share Purchase Program.  In 2001, Stratus’ Board of Directors authorized an open market stock purchase program for up to 0.7 million shares of Stratus’ common stock. The purchases may occur over time depending on many factors, including the market price of Stratus common stock; Stratus’ operating results, cash flow and financial position; and general economic and market conditions. In November 2013, Stratus' Board of Directors approved an increase in the open market share purchase program from 0.7 million shares to 1.7 million shares of Stratus common stock. Stratus' Comerica credit facility and its ASIP unsecured term loans, as modified, allowed for common stock purchases up to $1.0 million during 2013. Purchases under this program during 2013 included 81,990 shares for $1.0 million (an average of $11.68 per share), which Stratus purchased in private transactions. As of December 31, 2013, 31,655 shares remain available under this program. See Note 13 for purchases made subsequent to December 31, 2013.
	Employee Benefits.  Stratus maintains 401(k) defined contribution plans subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA). The 401(k) plans provide for an employer matching contribution equal to 100 percent of the participant’s contribution, subject to a limit of 5 percent of the participant’s annual salary. Stratus’ policy is to make an additional safe harbor contribution equal to 3 percent of each participant’s total compensation for corporate employees and 4 percent for ACL Live employees. The 401(k) plans also provide for discretionary contributions. Stratus’ contributions to the 401(k) plans totaled $0.4 million in 2013 and $0.3 million in 2012.

Commitments and Contingencies [Abstract]	'
Commitments and Contingencies Disclosure [Text Block]	'
	Commitments and Contingencies
	Construction Contracts.  Stratus had commitments under noncancelable construction contracts totaling $21.2 million at December 31, 2013. These commitments primarily included contracts for infrastructure work in connection with Amarra Drive Phase III and Section N at Barton Creek.
	Guarantees. At December 31, 2013, Stratus guarantees $0.2 million of the $0.9 million of outstanding debt at Crestview Station (see Note 6). Stratus also had guarantees related to the W Austin Hotel & Residences project (see Note 2).
	Letters of Credit.  As of December 31, 2013, Stratus had letters of credit committed totaling $4.1 million under its credit facility with Comerica.
	Rental Income.  As of December 31, 2013, Stratus’ minimum rental income, which includes scheduled rent increases under noncancelable long-term leases which extend through 2025, totaled $4.1 million in 2014, $4.0 million in 2015, $3.9 million in 2016, $3.7 million in 2017, $3.4 million in 2018 and $15.2 million thereafter.
	Operating Lease.  As of December 31, 2013, Stratus’ minimum annual contractual payments under its noncancelable long-term operating leases totaled $0.1 million in 2014 and 2015 and less than $0.1 million in 2016 and 2017. Total expense under Stratus’ operating leases amounted to $0.1 million in 2013 and 2012.
	Circle C Settlement.  On August 1, 2002, the City of Austin (the City) granted final approval of a development agreement (the Circle C settlement) and permanent zoning for Stratus’ real estate located within the Circle C community in southwest Austin. The Circle C settlement firmly established all essential municipal development regulations applicable to Stratus’ Circle C properties for thirty years. The City also provided Stratus $15 million of development fee credits, which are in the form of credit bank capacity, in connection with its future development of its Circle C and other Austin-area properties for waivers of fees and reimbursement for certain infrastructure costs. In addition, Stratus can elect to sell up to $1.5 million of the incentives per year to other developers for their use in paying City fees related to their projects as long as the projects are within the desired development zone, as defined within the Circle C settlement. To the extent Stratus sells the incentives to other developers, Stratus recognizes the income from the sale when title is transferred and compensation is received. As of December 31, 2013, Stratus has permanently used $11.4 million of its City-based development fee credits, including cumulative amounts sold to third parties totaling $5.1 million. Fee credits used for the development of Stratus’ properties effectively reduce the basis of the related properties and defer recognition of any gain associated with the use of the fees until the affected properties are sold. Stratus also has $1.4 million in credit bank capacity in use as temporary fiscal deposits as of December 31, 2013. Available credit bank capacity was $2.2 million at December 31, 2013.
	Environmental Regulations.  Stratus has made, and will continue to make, expenditures for protection of the environment. Increasing emphasis on environmental matters can be expected to result in additional costs, which will be charged against Stratus’ operations in future periods. Present and future environmental laws and regulations applicable to Stratus’ operations may require substantial capital expenditures that could adversely affect the development of its real estate interests or may affect its operations in other ways that cannot be accurately predicted at this time.
	Litigation.  Stratus may from time to time be involved in various legal proceedings of a character normally incident to the ordinary course of its business. Stratus believes that potential liability from any of these pending
	or threatened proceedings will not have a material adverse effect on Stratus’ financial condition or results of operations.

Business Segments [Abstract]	'
Segment Reporting Disclosure [Text Block]	'
	Business Segments
	Stratus currently has four operating segments: Real Estate Operations, Hotel, Entertainment and Commercial Leasing.
	The Real Estate Operations segment is comprised of Stratus’ real estate assets (developed, under development and undeveloped), which consist of its properties in the Barton Creek community, the Circle C community and Lantana, and the condominium units at the W Austin Hotel & Residences project.
	The Hotel segment includes the W Austin Hotel located at the W Austin Hotel & Residences project.
	The Entertainment segment includes ACL Live, a live music and entertainment venue and production studio at the W Austin Hotel & Residences project. In addition to hosting concerts and private events, this venue is the home of Austin City Limits, a television program showcasing popular music legends. The Entertainment segment also includes revenues and costs associated with events hosted at other venues, and the results of the Stageside Productions joint venture (see Note 2 for further discussion).
	The Commercial Leasing segment includes the office and retail space at the W Austin Hotel & Residences project, a retail building and a bank building in Barton Creek Village and 5700 Slaughter and the Parkside Village project in the Circle C community. In February 2012, Stratus sold the two office buildings at 7500 Rialto Boulevard (7500 Rialto). Accordingly, the operating results for 7500 Rialto are reported as discontinued operations in the table below (see Note 12).
	Stratus uses operating income or loss to measure the performance of each segment. Stratus allocates parent company general and administrative expenses that do not directly relate to an operating segment between the Real Estate Operations and Commercial Leasing segments based on projected annual revenues for each segment. General and administrative expenses related to the W Austin Hotel & Residences project are allocated to the Real Estate Operations, Hotel, Entertainment and Commercial Leasing segments based on projected annual revenues for the W Austin Hotel & Residences project. The following segment information reflects management's determinations that may not be indicative of what actual financial performance of each segment would be if it were an independent entity.
	Segment data presented below were prepared on the same basis as Stratus’ consolidated financial statements (in thousands).

	Discontinued Operations
	On February 27, 2012, Stratus sold 7500 Rialto to Lincoln Properties and Greenfield Partners (Lincoln Properties) for $27.0 million. Lincoln Properties paid Stratus $6.7 million ($5.7 million net to Stratus after closing and other costs) in cash and assumed Stratus' outstanding nonrecourse debt (the Lantana Promissory Note) of $20.3 million secured by the property. Stratus is providing a limited guaranty of debt service and other obligations on the Lantana Promissory Note up to $5.0 million, which will be reduced by $2.5 million on May 1, 2016, until January 1, 2018 (the maturity date for the Lantana Promissory Note). Stratus recognized $5.1 million of its $10.1 million gain on the sale in 2012 and expects the balance to be recorded as its obligations under the limited guaranty are relieved.
	The operating results and assets and liabilities for 7500 Rialto are presented in the financial statements as discontinued operations. The operations of 7500 Rialto previously represented a component of the Commercial Leasing segment (see Note 11).

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2013
Summary of Significant Accounting Policies [Abstract]	'
Consolidation, Policy [Policy Text Block]	'
	Business and Principles of Consolidation.  Stratus Properties Inc. (Stratus), a Delaware corporation, is engaged in the acquisition, development, management, operation and sale of commercial, hotel, entertainment, and multi- and single-family residential real estate properties located primarily in the Austin, Texas area. The real estate development and marketing operations of Stratus are conducted through its wholly owned subsidiaries, two consolidated joint ventures (see Notes 2 and 3) and through unconsolidated joint ventures (see “Investments in Unconsolidated Affiliates” below and Note 6). Stratus consolidates its wholly owned subsidiaries, subsidiaries in which Stratus has a controlling interest and variable interest entities in which Stratus is deemed the primary beneficiary. All significant intercompany transactions have been eliminated in consolidation.
	On February 27, 2012, Stratus sold its two office buildings at 7500 Rialto Boulevard (7500 Rialto). As a result, 7500 Rialto is reported as discontinued operations (see Note 12).
Concentration Risk Disclosure [Text Block]	'
	Concentration of Risks.  Stratus primarily conducts its operations in Austin, Texas. Consequently, any significant economic downturn in the Austin market could potentially have an effect on Stratus’ business, results of operations and financial condition.
Use of Estimates, Policy [Policy Text Block]	'
	Use of Estimates.  The preparation of financial statements in conformity with accounting principles generally accepted in the United States (U.S.) requires management to make estimates and assumptions that affect the amounts reported in these financial statements and accompanying notes. The more significant estimates include the (1) estimates of future cash flow from development and sale of real estate properties used in the assessment of impairments, (2) valuation allowances for deferred tax assets, (3) allocation of certain indirect costs and (4) useful lives for depreciation. Actual results could differ from those estimates.
Real Estate, Policy [Policy Text Block]	'
	Real Estate and Commercial Leasing Assets.  Real estate held for sale is stated at the lower of cost or fair value less costs to sell. The cost of real estate held for sale includes acquisition, development, construction and carrying costs, and other related costs through the development stage. Real estate under development and land available for development are stated at cost. Real estate held for investment, which includes the hotel and entertainment venue at the W Austin Hotel & Residences project and Stratus' commercial leasing assets, is stated at cost, less accumulated depreciation. Stratus capitalizes interest on funds used in developing properties from the date of initiation of development activities through the date the property is substantially complete and ready for sale or lease. Common costs are allocated based on the relative fair value of individual land parcels. Certain carrying costs are capitalized on properties currently under active development. Stratus capitalizes improvements that increase the value of commercial leasing properties and have useful lives greater than one year. Costs related to repairs and maintenance are charged to expense as incurred.
	Stratus performs an impairment test when events or circumstances indicate that an asset’s carrying amount may not be recoverable. Events or circumstances that Stratus considers indicators of impairment include significant decreases in market values, adverse changes in regulatory requirements (including environmental laws), significant budget overruns for properties under development, and current period or projected operating cash flow losses from rental properties. Impairment tests for properties to be held and used, including properties under development, involve the use of estimated future net undiscounted cash flows expected to be generated from the use of the property and its eventual disposition. If projected undiscounted cash flow from properties to be held and used is less than the related carrying amount, then a reduction of the carrying amount of the long-lived asset to fair value is required. Measurement of the impairment loss is based on the fair value of the asset. Generally, Stratus determines fair value using valuation techniques such as discounted expected future cash flows. Impairment tests for properties held for sale involve management estimates of fair value based on estimated market values for similar properties in similar locations and management estimates of costs to sell. If estimated fair value less costs to sell is less than the related carrying amount, then a reduction of the carrying amount of the asset to fair value less costs to sell is required.
	Stratus recorded no impairment charges for the years ended December 31, 2013 and 2012. Should market conditions deteriorate in the future or other events occur that indicate the carrying amount of Stratus’ real estate assets may not be recoverable, Stratus will reevaluate the expected cash flows from each property to determine whether any impairment exists.
Depreciation, Depletion, and Amortization [Policy Text Block]	'
	Depreciation.  Commercial leasing properties are depreciated on a straight-line basis over their estimated life of between 30 and 40 years. The hotel and entertainment venue properties are depreciated on a straight-line basis over their estimated life of 35 years. Furniture, fixtures and equipment are depreciated on a straight-line basis over a three to five-year period. Tenant improvements are depreciated over the related lease terms.
Equity Method Investments, Policy [Policy Text Block]	'
	Investments in Unconsolidated Affiliates.  Stratus has interests in three unconsolidated affiliates, which it accounts for under the equity method (see Note 6)
Other Assets Disclosure [Text Block]	'
	Other Assets.  Other assets primarily consist of restricted cash, deferred financing and leasing costs, prepaid insurance, tenant and other accounts receivable, and notes and interest receivable. Deferred financing costs are amortized using the straight-line method over the term of the related debt, which approximates the effective interest method, to interest expense. Deferred leasing costs are amortized to cost of sales using the straight-line method over the related lease terms.
Accrued Property Taxes [Policy Text Block]	'
	Accrued Property Taxes.  Stratus estimates its property taxes based on prior year property tax payments and other current events that may impact the amount. Upon receipt of the property tax bill, Stratus adjusts its accrued property tax balance at year-end to the actual amount of taxes due in January. Accrued property taxes totaled $5.1 million at December 31, 2013, and $5.2 million at December 31, 2012.
Revenue Recognition, Policy [Policy Text Block]	'
	Revenue Recognition.  Revenues from property sales are recognized when the risks and rewards of ownership are transferred to the buyer, when the consideration received can be reasonably determined and when Stratus has completed its obligations to perform certain supplementary development activities, if any exist, at the time of the sale. Consideration is reasonably determined and considered likely of collection when Stratus has signed sales agreements and has determined that the buyer has demonstrated a commitment to pay. The buyer’s commitment to pay is supported by the level of their initial investment, Stratus’ assessment of the buyer’s credit standing and Stratus’ assessment of whether the buyer’s stake in the property is sufficient to motivate the buyer to honor their obligation to pay.
	Stratus' revenues from hotel operations are primarily derived from room reservations and food and beverage sales. Revenue is recognized when rooms are occupied and services have been rendered. Taxes collected from customers and submitted to taxing authorities are not recorded in revenue.
	Stratus' revenues from entertainment operations are primarily derived from ticket sales; sponsorships, personal seat licenses and suite sales; and sales of concessions and merchandise. Revenues from ticket sales are recognized after the corresponding performance occurs. Revenues from sponsorships and other revenue not related to a single event are classified as deferred revenue and generally amortized over the operating season or term of the contract. Revenues from concessions and merchandise sales are recognized at the time of sale.
	Stratus recognizes its rental income based on the terms of its signed leases with tenants on a straight-line basis. Recoveries from tenants for taxes, insurance and other commercial property operating expenses are recognized as revenues in the period the related costs are incurred. Stratus recognizes sales commissions and management and development fees when earned, as properties are sold or when the services are performed.
	A summary of Stratus’ revenues follows (in thousands):
		Years Ended December 31,
		2013				2012
	Revenues:
	Developed property sales	$	63,676			$	45,716
	Undeveloped property sales	3,266				15,837
	Hotel	39,234				35,402
	Entertainment	15,481				13,799
	Rental	5,406				4,422
	Commissions and other	647				561
	Total revenues	$	127,710			$	115,737
Cost of Sales, Policy [Policy Text Block]	'
	Cost of Sales.  Cost of sales includes the cost of real estate sold as well as costs directly attributable to the properties sold such as marketing, maintenance and property taxes. Cost of sales also includes operating costs and depreciation for properties held for investment and municipal utility district reimbursements. A summary of Stratus’ cost of sales follows (in thousands):
		Years Ended December 31,
		2013				2012
	Cost of developed property sales	$	48,732			$	38,364

	Municipal utility district reimbursements (see below)	—				(688		)
	Depreciation	9,053				9,165
	Other, net	(1,148		)	a	433
	Total cost of sales	$	108,257			$	106,424
	a. Includes a credit of $1.1 million related to the recovery of building repair costs associated with damage caused by the June 2011 balcony glass breakage incidents at the W Austin Hotel & Residences project.
	Gross profit on condominium sales from the W Austin Hotel & Residences project is based on estimates of total project sales value and total project costs for the condominiums. When estimates of sales value or project costs are revised, gross profit is adjusted in the period of change so that cumulative project earnings reflect the revised profit estimate. Stratus revised estimates of projected aggregate profit margins on condominium units at the W Austin Hotel & Residences project, resulting in a charge to cost of sales totaling $1.5 million in 2012.
Allocation of Overhead Costs [Policy Text Block]	'
	Allocation of Overhead Costs.  Stratus has historically allocated a portion of its overhead costs to both capitalized real estate costs and cost of sales based on the percentage of time certain of its employees, comprising its indirect overhead pool, worked in the related areas (i.e. construction and development for capital assets and sales and marketing for cost of sales). Stratus capitalizes only direct and certain indirect project costs associated with the acquisition, development and construction of a real estate project. Indirect costs include allocated costs associated with certain pooled resources (such as office supplies, telephone and postage) which are used to support Stratus’ development projects, as well as general and administrative functions. Allocations of pooled resources are based only on those employees directly responsible for development (i.e., project managers and subordinates). Stratus charges to expense indirect costs that do not clearly relate to a real estate project, such as salaries and costs related to its Chief Executive Officer and Chief Financial Officer.
Municipal Utility District Reimbursements [Policy Text Block]	'
	Municipal Utility District Reimbursements.  Stratus receives Barton Creek Municipal Utility District (MUD) reimbursements for certain infrastructure costs incurred in the Barton Creek area. Prior to 1996, Stratus capitalized infrastructure costs to its properties as those costs were incurred. Subsequently, those costs were charged to cost of sales as properties were sold. In 1996, following the 1995 creation of MUDs, Stratus began capitalizing the infrastructure costs to a separate MUD property category. MUD reimbursements received for infrastructure costs incurred prior to 1996 are reflected as a reduction of cost of sales, while other MUD reimbursements represent a reimbursement of the cost of MUD properties and are recorded as a reduction of the related asset’s carrying amount or cost of sales if the property has been sold. Stratus has long-term agreements with seven independent MUDs in Barton Creek to build the MUDs’ utility systems and to be eligible for future reimbursements for the related costs. The amount and timing of MUD reimbursements depends upon the respective MUD having a sufficient tax base within its district to issue bonds and obtaining the necessary state approval for the sale of the bonds. Because the timing of the issuance and approval of the bonds is subject to considerable uncertainty, coupled with the fact that interest rates on such bonds cannot be fixed until they are approved, the amounts associated with MUD reimbursements are not known until approximately one month before the MUD reimbursements are received. To the extent the reimbursements are less than the costs capitalized, Stratus records a loss when that determination is made. MUD reimbursements represent the actual amounts received.
Advertising Costs, Policy [Policy Text Block]	'
	Advertising Costs.  Advertising costs are expensed as incurred and are included as a component of cost of sales. Advertising costs totaled $0.9 million in 2013 and $0.6 million in 2012.
Income Tax, Policy [Policy Text Block]	'
	Income Taxes.  Stratus accounts for deferred income taxes utilizing an asset and liability method, whereby deferred tax assets and liabilities are recognized based on the tax effects of temporary differences between the financial statements and the tax basis of assets and liabilities, as measured by current enacted tax rates. The effect on deferred income tax assets and liabilities of a change in tax rates or laws is recognized in income in the period in which such changes are enacted. Stratus periodically evaluates the need for a valuation allowance to reduce deferred tax assets to estimated recoverable amounts. Stratus establishes a valuation allowance to reduce its deferred tax assets and records a corresponding charge to earnings if it is determined, based on available evidence at the time, that it is more likely than not that any portion of the deferred tax assets will not be realized. In evaluating the need for a valuation allowance, Stratus estimates future taxable income based on projections and ongoing tax strategies. This process involves significant management judgment about assumptions that are subject to change based on variances between projected and actual operating performance and changes in Stratus’ business environment or operating or financial plans. See Note 8 for further discussion.
Earnings Per Share, Policy [Policy Text Block]	'
	Earnings Per Share.  Stratus’ basic net income per share of common stock was calculated by dividing the net income (loss) attributable to Stratus common stock by the weighted-average shares of common stock outstanding during the period. A reconciliation of net income (loss) and weighted-average shares of common stock outstanding for purposes of calculating diluted net income (loss) per share (in thousands, except per share amounts) for the years ended December 31 follows:
		2013				2012
	Net income (loss)	$	5,894			$	(4,313	)
	Net (income) loss attributable to noncontrolling interests	(3,309		)		2,727
	Net income (loss) attributable to Stratus common stock	$	2,585			$	(1,586	)
	Weighted-average shares of Stratus common stock outstanding	8,077				7,966
	Add shares issuable upon exercise or vesting of:
	Dilutive stock options	7			a	—
	Restricted stock units	27				—
	Weighted-average shares of Stratus common stock outstanding for purposes of calculating diluted net income (loss) per share	8,111				7,966
	Diluted net income (loss) per share attributable to Stratus common stock	$	0.32			$	(0.20	)
	a. Excludes shares of Stratus common stock associated with outstanding stock options with exercise prices less than the average market price of Stratus' common stock that were anti-dilutive based on the treasury stock method totaling approximately 1,250 shares for the year ended December 31, 2013.
	Outstanding stock options with exercise prices greater than the average market price for Stratus' common stock during the period are excluded from the computation of diluted net income (loss) per share of common stock. Excluded were approximately 63,500 stock options with a weighted average exercise price of $20.85 for 2013. Stock options and restricted stock units representing approximately 134,300 shares for 2012 were excluded from weighted-average common shares outstanding for purposes of calculating diluted net income (loss) per share because they were anti-dilutive, either because inclusion of the options would result in a decrease of Stratus' net loss per share, or the stock options had exercise prices greater than the average market price of Stratus' common stock.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	'
	Stock-Based Compensation.  Compensation costs for share-based payments to employees, including stock options, are measured at fair value and charged to expense over the requisite service period for awards that are expected to vest. The fair value of stock options is determined using the Black-Scholes option valuation model. In addition, for restricted stock units, compensation costs are recognized based on the fair value on the date of grant. Stratus estimates forfeitures at the time of grant and revises those estimates in subsequent periods if actual forfeitures differ from those estimates through the final vesting date of the awards. See Note 9 for further discussion.
