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 primarily in the 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.
	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 incurred 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, 2014 and 2013. 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 (associated with the joint venture between Stratus and Canyon-Johnson Urban Fund II, L.P. (Canyon-Johnson) (the Block 21 Joint Venture)), 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 for such year. Accrued property taxes included in accrued liabilities on the balance sheets totaled $5.0 million at December 31, 2014, and $5.1 million at December 31, 2013.
	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,
		2014				2013
	Revenues:
	Hotel	$	42,354			$	39,234
	Developed property sales	25,674				63,676
	Undeveloped property sales	—				3,266
	Entertainment	19,048				15,481
	Commercial leasing	6,625				5,406
	Commissions and other	410				647
	Total revenues	$	94,111			$	127,710
	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,
		2014				2013
	Hotel	$	30,746			$	29,483
	Cost of developed property sales	16,466				48,732
	Cost of undeveloped property sales	43				1,122
	Entertainment	14,431				12,922
	Commercial leasing	3,138				2,670
	Project expenses and allocation of overhead costs (see below)	3,543				5,423
	Depreciation	8,977				9,053
	Other, net	598			a	(1,148		)	a
	Total cost of sales	$	77,942			$	108,257
	a. Includes a credit of $0.4 million in 2014 and $1.1 million in 2013 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.
	Allocation of Overhead Costs.  Stratus allocates 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 all 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 obtain 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 $0.8 million in 2014 and $0.9 million in 2013.
	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 attributable to common stock by the weighted-average shares of common stock outstanding during the period. A reconciliation of net income and weighted-average shares of common stock outstanding for purposes of calculating diluted net income per share (in thousands, except per share amounts) for the years ended December 31 follows:
		2014				2013
	Net income	$	18,157			$	5,894
	Net income attributable to noncontrolling interests	(4,754		)		(3,309		)
	Net income attributable to common stock	$	13,403			$	2,585
	Weighted-average shares of common stock outstanding	8,037				8,077
	Add shares issuable upon exercise or vesting of:
	Dilutive stock options	11				7			a
	Restricted stock units	30			b	27
	Weighted-average shares of common stock outstanding for purposes of calculating diluted net income per share	8,078				8,111
	Diluted net income per share attributable to common stock	$	1.66			$	0.32
	a.	Excludes 1,000 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 for the year ended December 31, 2013.
	b.	Excludes 36,000 shares of common stock that were anti-dilutive based on the treasury stock method.
	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 per share of common stock. Excluded were 42,000 stock options with a weighted average exercise price of $23.44 for 2014, and 64,000 stock options with a weighted average exercise price of $20.85 for 2013.
	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. [Abstract]
Joint Venture [Text Block]	Joint Venture with Canyon-Johnson Urban Fund II, L.P.
	Stratus and Canyon-Johnson are participants in the Block 21 Joint Venture 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 Block 21 Joint Venture, and Canyon-Johnson has an approximate 60 percent interest. As of December 31, 2014, cumulative capital contributions totaled $71.9 million for Stratus and $94.0 million for Canyon-Johnson. As of December 31, 2014, the inception-to-date distributions totaled $52.7 million to Stratus, including $8.0 million in 2014, and $61.6 million to Canyon-Johnson, including $11.0 million in 2014.
	Upon formation of the Block 21 Joint Venture, Stratus performed an initial evaluation and concluded that the Block 21 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 Stratus as primary beneficiary of the Block 21 Joint Venture 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 Block 21 Joint Venture in accordance with applicable accounting guidance.

	Profits and losses among partners in a real estate venture are allocated based on how changes in net assets of the venture would affect cash payments to the partners over the life of the venture and on its liquidation. The amount of the ultimate profits earned by the Block 21 Joint Venture 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 Block 21 Joint Venture's cumulative profits or losses are allocated based on a hypothetical liquidation of the Block 21 Joint Venture's net assets as of each balance sheet date. As of December 31, 2014, the cumulative earnings of the Block 21 Joint Venture were 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 Block 21 Joint Venture's initial capital contributions to Stageside totaled $0.3 million, and the Block 21 Joint Venture will contribute additional capital as necessary to fund the working capital needs of Stageside. The Block 21 Joint Venture has a 100 percent capital funding interest and a 40 percent residual and voting interest in Stageside. The joint venture performed an evaluation and concluded Stageside is a VIE and that the Block 21 Joint Venture is the primary beneficiary. Accordingly, the results of Stageside are consolidated in the Block 21 Joint Venture's financial statements.

	In 2011, Stratus entered into a joint venture (the Parkside Village Joint Venture) with Moffett Holdings, LLC (Moffett Holdings) for the development of Parkside Village, a retail project in the Circle C community in southwest Austin, Texas. On March 3, 2014, Moffett Holdings redeemed and purchased the membership interest in Moffett Holdings held by LCHM Holdings, LLC (LCHM Holdings). In connection with the redemption, (1) LCHM Holdings received the 625,000 shares of Stratus common stock held by Moffett Holdings and (2) LCHM Holdings entered into an assignment and assumption agreement pursuant to which Moffett Holdings assigned to LCHM Holdings its rights and obligations under the Investor Rights Agreement between Moffett Holdings and Stratus dated as of March 15, 2012.

Fair Value Measurement [Abstract]
Fair Value Disclosures [Text Block]	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 and cash equivalents, restricted cash, accounts payable and accrued liabilities) approximates 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, 2014				December 31, 2013
		Carrying		Fair		Carrying		Fair
		Value		Value		Value		Value
	Assets:
	Interest rate cap agreement	$	79	$	79	$	351	$	351

	Interest rate swap	596		596		32		32
	Debt	196,477		196,856		151,332		151,584
	Interest Rate Cap Agreement. On September 30, 2013, the Block 21 Joint Venture 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 relating to the W Austin Hotel & Residences project (the BoA loan), 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 Parkside Village Joint Venture entered into an interest rate swap agreement with Comerica Bank that effectively converts the variable rate portion of Parkside Village's loan from Comerica Bank (the Parkside Village loan) from one-month LIBOR to a fixed rate of 2.3 percent. With the interest rate swap agreement in place, the Parkside Village Joint Venture's 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.

	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 (the Crestview Station Joint Venture), is a single-family, multi-family, retail and office development located on the site of a commuter line. The Crestview Station Joint Venture sold substantially all of its multi-family and commercial properties in 2007 and one commercial site in 2008. The Crestview Station Joint Venture sold the remaining residential land to DR Horton, as follows (in millions, except lots closed):
	Closing Date		Lots Closed	Sale Price		Gross Profit
	Apr-12		74	$	3.8	$	0.4

			303	$	17.5	$	3.7
	At December 31, 2014, the Crestview Station Joint Venture had one commercial site remaining. 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, 2014, 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, 2014, 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 regarding the activities that most significantly impact the VIEs' economic performance is shared equally between the partners. Stratus accounts for its investments in Stump Fluff and Guapo using the equity method.

	BoA loan. On September 30, 2013, the Block 21 Joint Venture 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 Block 21 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 Block 21 Joint Venture entered into an interest rate cap agreement for the BoA loan (see Note 5). The Block 21 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 Block 21 Joint Venture, including environmental indemnification and other customary carve-out obligations. The BoA loan contains customary financial covenants and other restrictions.
	Comerica credit facility. Stratus has a $48.0 million credit facility with Comerica, 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 in May 2015. Stratus' obligations under the credit facility are secured by substantially all of Stratus' assets, except for properties that are encumbered by separate loan financing. The credit facility 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. Stratus is currently negotiating a new credit facility with Comerica that is expected to be completed in second-quarter 2015.
	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 balance 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 below), 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, 2014, a total of $23.1 million was outstanding under the revolving line of credit, no amounts outstanding under the letters of credit tranche ($2.7 million of letters of credit committed) and no amounts were outstanding under the construction loan ($1.9 million of letters of credit committed).

The Parkside Village loan is secured by a lien on the assets of the Parkside Village project, which had a net book value of $16.9 million at December 31, 2014, and Stratus has provided a limited guaranty. As of December 31, 2014, the amount outstanding was $18.9 million with $0.8 million available.

On November 7, 2014, the Stratus subsidiary and PlainsCapital Bank entered into an amendment to the loan agreement to effect the syndication of a portion of the aggregate principal amount of the Lakeway Construction loan with Southside Bank. Pursuant to the amendment, PlainsCapital Bank has committed $37.9 million and Southside Bank has committed $25.0 million under the Lakeway Construction loan. The loan is secured by the related land, which had a net book value of $32.6 million at December 31, 2014. As of December 31, 2014, Stratus had $16.6 million outstanding under the Lakeway Construction loan, which matures on September 29, 2019.

As of December 31, 2014, the amount outstanding was $6.9 million.
	Barton Creek Village term loan. On June 27, 2014, Stratus entered into a $6.0 million term loan agreement with PlainsCapital Bank (the Barton Creek Village term loan), that matures on June 27, 2024.

	In fourth-quarter 2014, Stratus evaluated the recoverability of its deferred tax assets, considering available positive and negative evidence, including recent earnings history and forecasts of future taxable income. As a result, Stratus concluded that there was sufficient positive evidence that its $11.8 million of deferred tax assets (net of deferred tax liabilities) will be realized. Accordingly, Stratus reversed the valuation allowance on its deferred tax assets as of December 31, 2014. Stratus recorded credits totaling $12.1 million in 2014 and $1.4 million in 2013 to the provision for income taxes to adjust the valuation allowances.
	Stratus’ future results of operations may be negatively impacted by an inability to realize a tax benefit for future tax losses or for items that will generate additional deferred tax assets.

Stratus' deferred tax assets related to the U.S. net operating loss carry forwards at December 31, 2014, did not include an additional $5.2 million of net operating losses in relation to excess tax benefits on stock option exercises and restricted stock units vested because these benefits have not yet been realized. At December 31, 2014, excluding these losses, Stratus had operating loss carryforwards totaling $0.1 million that expire between 2029 and 2031.
	During 2014 and 2013, 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,
		2014			2013
	Balance at January 1	$	854		$	562
	Additions for tax positions related to the current year	221			274
	Additions for tax positions related to prior years	85			18
	Balance at December 31	$	1,160		$	854
	As of December 31, 2014, there was $1.2 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, 2014, 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 2010.

Stockholders' Equity Note [Abstract]
Shareholders' Equity and Share-based Payments [Text Block]	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' stockholders 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 139,000 shares under the 2013 Stock Incentive Plan, 1,875 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, 2014.
	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,
		2014			2013
	Stock options awarded to directors	$	6		$	14
	Restricted stock units awarded to employees and directors	474			324
	Impact on net income before income taxes	$	480		$	338
	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). Stratus has not granted stock options since 2011. A summary of stock options outstanding as of December 31, 2014, and changes during the year ended December 31, 2014, follow:
		Number of		Weighted			Weighted	Aggregate
		Options		Average			Average	Intrinsic
				Option Price			Remaining	Value
							Contractual	$0
							Term (years)
	Balance at January 1	76,875		$	18.42
	Exercised	(5,000	)	13.06
	Expired	(28,750	)	16.02
	Balance at December 31	43,125		20.65			3.1	$	81
	Vested and exercisable at December 31	41,875		20.97			2.9	$	77
	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. Our current ability to pay dividends is restricted by terms of our credit facility. There were no stock options granted during 2014 or 2013.
	The intrinsic value of options exercised during 2014 and 2013 was less than $0.1 million. A total of 2,500 stock options vested during 2014 and 3,750 vested during 2013, with weighted-average grant-date fair values of $6.63 per option and $5.91 per option, respectively. As of December 31, 2014, there were 1,250 stock options unvested with a weighted-average grant-date fair value of $6.91 per option. As of December 31, 2014, Stratus had no unrecognized compensation cost related to unvested stock options.
	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, 2014, and activity during the year ended December 31, 2014, is presented below:
		Number of		Aggregate
		Restricted		Intrinsic
		Stock Units		Value
				$0
	Balance at January 1	100,875
	Granted	48,000
	Vested	(35,375	)
	Balance at December 31	113,500		$	1,566
	The total grant date fair value of restricted stock units granted during the year ended December 31, 2014, was $0.8 million. The total intrinsic value of restricted stock units vesting during the year ended December 31, 2014, was $0.6 million. As of December 31, 2014, Stratus had $1.1 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.
	The following table includes amounts related to exercises of stock options and vesting of restricted stock units for the years ended December 31, 2014, and 2013 (in thousands, except shares of Stratus common stock tendered):
		2014			2013
	Stratus shares tendered to pay the exercise
	price and/or the minimum required taxesa	10,917			8,132
	Cash received from stock option exercises	$	65		$	91
	Amounts Stratus paid for employee taxes	$	125		$	9
	a.	Under terms of the related plans and agreements, 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.
	Share Purchase Program.  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. 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. Purchases under this program during 2014 included 39,960 shares for $0.7 million (an average of $17.00 per share), which Stratus purchased in private transactions. As of December 31, 2014, 991,695 shares remain available under this program.
	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 both 2014 and 2013.

Commitments_and_Contingencies

Commitments and Contingencies	12 Months Ended
	Dec. 31, 2014
Commitments and Contingencies [Abstract]
Commitments and Contingencies Disclosure [Text Block]	Commitments and Contingencies
	Construction Contracts.  Stratus had commitments under noncancelable construction contracts totaling $55.3 million at December 31, 2014. These commitments primarily included contracts for construction of improvements for the Tecoma apartments at Barton Creek and The Oaks and Lakeway.
	Guarantees. At December 31, 2014, Stratus had guarantees related to the W Austin Hotel & Residences project (see Note 2).
	Letters of Credit.  As of December 31, 2014, Stratus had letters of credit committed totaling $4.6 million under its credit facility with Comerica (see Note 7).
	Rental Income.  As of December 31, 2014, Stratus’ minimum rental income, including scheduled rent increases under noncancelable long-term leases which extend through 2025, totaled $4.8 million in 2015, $4.8 million in 2016, $4.8 million in 2017, $4.5 million in 2018, $3.8 million in 2019 and $15.3 million thereafter.
	Operating Lease.  As of December 31, 2014, Stratus’ minimum annual contractual payments under its noncancelable long-term operating leases totaled $0.1 million for each of 2015 and 2016 and less than $0.1 million in 2017. Total expense under Stratus’ operating leases amounted to $0.1 million in 2014 and 2013.
	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, 2014, Stratus had 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 had $1.4 million in credit bank capacity in use as temporary fiscal deposits as of December 31, 2014. Available credit bank capacity was $2.2 million at December 31, 2014.
	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.

Subsequent Events [Abstract]
Subsequent Events [Text Block]	Subsequent Events
	On January 8, 2015, a Stratus subsidiary entered into a $34.1 million construction loan agreement with Comerica Bank (the Tecoma Construction loan), to fund the development and construction of the first phase of a multi-family development in Section N of Barton Creek, which is referred to as the Tecoma Barton Creek multi-family project. The interest rate is a LIBOR-based rate (as defined in the loan agreement) plus 2.5 percent. The Tecoma Construction loan matures on January 8, 2018, and Stratus has the option to extend the maturity date for two additional twelve-month periods, subject to certain debt service coverage conditions. The Tecoma Construction loan is fully guaranteed by Stratus until certain operational milestones (as defined in the loan agreement) are met.
	In 2012, Stratus sold 7500 Rialto, an office building in Lantana, and recognized a gain of $5.1 million and deferred a gain of $5 million related to a guaranty provided to the lender in connection with the buyer's assumption of the loan. The guaranty was released in January 2015, and Stratus will recognize the $5 million deferred gain in first-quarter 2015.
	Stratus evaluated events after December 31, 2014, and through the date the financial statements were issued, and determined any events or transactions occurring during this period that would require recognition or disclosure are appropriately addressed in these financial statements.

Consolidation, Policy [Policy Text Block]	Business and Principles of Consolidation.  Stratus Properties Inc. (Stratus), a Delaware corporation, is engaged primarily in the 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.
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 incurred 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, 2014 and 2013. 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 (associated with the joint venture between Stratus and Canyon-Johnson Urban Fund II, L.P. (Canyon-Johnson) (the Block 21 Joint Venture)), 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 for such year. Accrued property taxes included in accrued liabilities on the balance sheets totaled $5.0 million at December 31, 2014, and $5.1 million at December 31, 2013.
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,
		2014				2013
	Revenues:
	Hotel	$	42,354			$	39,234

	Commissions and other	410				647
	Total revenues	$	94,111			$	127,710
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,
		2014				2013
	Hotel	$	30,746			$	29,483
	Cost of developed property sales	16,466				48,732
	Cost of undeveloped property sales	43				1,122
	Entertainment	14,431				12,922
	Commercial leasing	3,138				2,670
	Project expenses and allocation of overhead costs (see below)	3,543				5,423
	Depreciation	8,977				9,053
	Other, net	598			a	(1,148		)	a
	Total cost of sales	$	77,942			$	108,257
	a. Includes a credit of $0.4 million in 2014 and $1.1 million in 2013 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.
Allocation of Overhead Costs [Policy Text Block]	Allocation of Overhead Costs.  Stratus allocates 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 all 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 obtain 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 $0.8 million in 2014 and $0.9 million in 2013.
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 attributable to common stock by the weighted-average shares of common stock outstanding during the period. A reconciliation of net income and weighted-average shares of common stock outstanding for purposes of calculating diluted net income per share (in thousands, except per share amounts) for the years ended December 31 follows:
		2014				2013
	Net income	$	18,157			$	5,894
	Net income attributable to noncontrolling interests	(4,754		)		(3,309		)
	Net income attributable to common stock	$	13,403			$	2,585
	Weighted-average shares of common stock outstanding	8,037				8,077
	Add shares issuable upon exercise or vesting of:
	Dilutive stock options	11				7			a
	Restricted stock units	30			b	27
	Weighted-average shares of common stock outstanding for purposes of calculating diluted net income per share	8,078				8,111
	Diluted net income per share attributable to common stock	$	1.66			$	0.32
	a.	Excludes 1,000 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 for the year ended December 31, 2013.
	b.	Excludes 36,000 shares of common stock that were anti-dilutive based on the treasury stock method.
	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 per share of common stock. Excluded were 42,000 stock options with a weighted average exercise price of $23.44 for 2014, and 64,000 stock options with a weighted average exercise price of $20.85 for 2013.
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.
