Discontinued Operations and Disposal Groups [Abstract]
Disposal Groups, Including Discontinued Operations, Disclosure [Text Block]	DISPOSITIONS The Oaks at Lakeway. On February 15, 2017, Stratus sold The Oaks at Lakeway to FHF I Oaks at Lakeway, LLC for $114.0 million in cash. Net cash proceeds were $50.8 million after repayment of the Lakeway construction loan. Stratus used a portion of these net cash proceeds to pay indebtedness outstanding under the Comerica Bank credit facility. The parties entered into three master lease agreements at closing: (1) one covering unleased in-line retail space, with a 5 -year term, (2) one covering four unleased pad sites, three of which have 10 -year terms, and one of which has a 15 -year term, and (3) one covering the hotel pad with a 99 -year term. As specified conditions are met, primarily consisting of the tenant executing a lease, commencing payment of rent and taking occupancy, leases will be assigned to the purchaser and the corresponding property will be removed from the master lease, reducing Stratus' master lease payment obligations. Stratus' master lease payment obligation, which currently approximates $180 thousand per month, is expected to decline over time until leasing is complete and all leases are assigned to the purchaser. Stratus agreed to guarantee the obligations of its selling subsidiary under the sales agreement, up to a liability cap of two percent of the purchase price. This cap does not apply to Stratus' obligation to satisfy the selling subsidiary's indemnity obligations for its broker commissions or similar compensation or Stratus' liability in guaranteeing the selling subsidiary's obligations under the master leases. To secure its obligations under the master leases, Stratus has provided a $1.5 million irrevocable letter of credit with a three-year term. At the date of sale, Stratus allocated the purchase price for The Oaks at Lakeway between two performance obligations based on the relative fair values of each. The first performance obligation, to deliver the completed and leased portion of the property, was performed on the date of sale. The second performance obligation was to complete construction of the remaining buildings and leasing of the vacant space. The obligations under master leases were considered variable consideration and are recorded as reductions to the contract liability. The hotel pad was leased to a hotel operator under a ground lease at the date of sale. However, the hotel tenant had not commenced rent payments or construction of the hotel. At the date of the sale, primarily because of the uncertainty related to the hotel tenant’s performance under its ground lease, the probability-weighted estimate of the obligations under the master leases reduced the sale consideration such that no gain was recognized on the sale. Once the hotel tenant began paying rent in May 2017 and obtained construction financing and commenced construction of the hotel in August 2017, the probability-weighted estimate of Stratus’ obligations under the master leases was significantly reduced, and a gain of $24.3 million related to the first performance obligation was recognized in third-quarter 2017. A contract liability of $10.5 million is presented as a deferred gain in the consolidated balance sheets at June 30, 2018 , compared with $11.3 million at December 31, 2017. The reduction in the deferred gain balance primarily reflects master lease payments. The contract liability, as reduced by future master lease payments, will be recognized as additional gain as Stratus fulfills the remaining performance obligation. Upon the sale of The Oaks at Lakeway, HEB earned a profit participation of $2.5 million (of which $2.2 million was paid at closing), which is presented separately in the consolidated statements of comprehensive loss. Barton Creek Village. On February 28, 2017, Stratus completed the sale of its 3,085 -square-foot bank building and an adjacent undeveloped 4.1 acre tract of land in Barton Creek, for $3.1 million and recorded a gain on the sale of $1.1 million . In connection with the sale, a $2.1 million paydown was made on the Barton Creek Village term loan.

Fair Value Disclosures [Abstract]
Fair Value Measurements [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): June 30, 2018 December 31, 2017 Carrying Value Fair Value Carrying Value Fair Value Assets: Interest rate swap agreement $ 123 $ 123 $ — $ — Liabilities: Debt $ 265,872 $ 269,404 $ 221,470 $ 224,632 Interest rate swap agreement — — 134 134 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. Interest Rate Swap Agreement. The interest rate swap does not qualify for hedge accounting and changes in its fair value are recorded in the consolidated statements of comprehensive loss. Stratus 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.

The components of Stratus' debt are as follows (in thousands): June 30, 2018 December 31, 2017 Goldman Sachs loan $ 144,226 $ 145,195 Comerica Bank credit facility 43,877 25,765 Santal Phase I construction loan 32,572 31,864 Barton Creek Village term loan 3,330 3,375 Amarra Villas credit facility 4,490 5,247 West Killeen Market construction loan 5,936 5,378 Jones Crossing construction loan 10,170 4,646 Lantana Place construction loan 14,080 — Santal Phase II construction loan 7,191 — Total debt a $ 265,872 $ 221,470 a. Includes net reductions for unamortized debt issuance costs of $2.5 million at June 30, 2018 , and $2.1 million at December 31, 2017. On June 29, 2018, Stratus entered into a loan agreement with Comerica Bank to modify, increase and extend Stratus’ Comerica Bank credit facility, which was scheduled to mature on November 30, 2018. The new loan agreement provides for (1) an increase in the revolving credit facility from $45.0 million to $60.0 million , (2) a $7.5 million sublimit for letters of credit issuance and (3) an extension of the maturity date from November 30, 2018, to June 29, 2020. Advances under the credit facility bear interest at the annual London Interbank Offered Rate (LIBOR) plus 4.0 percent . The Comerica Bank credit facility is secured by substantially all of Stratus' assets, except for properties that are encumbered by separate debt financing. The loan agreement contains financial covenants usual and customary for loan agreements of this nature, including a requirement that Stratus maintains a net asset value of $125 million and an aggregate promissory note debt-to-gross asset value of less than 50 percent. As of June 30, 2018 , Stratus had $12.0 million available under its $60.0 million Comerica Bank revolving credit facility, with $4.1 million of letters of credit committed against the available balance. As discussed in Note 3, on June 19, 2018, Stratus entered into a $26 million construction loan with Texas Capital Bank (The Saint Mary construction loan) to finance the initial phase of The Saint Mary. Stratus will fully guaranty The Saint Mary construction loan. The repayment guaranty will be reduced to 50 percent upon issuance of a certificate of occupancy for The Saint Mary and will be eliminated when the project debt service coverage ratio equals or exceeds 1.25:1.0. Interest is variable at the one-month LIBOR plus 3.0 percent . Payments of interest only will be due and payable monthly, and outstanding principal is payable at maturity of June 19, 2021. Outstanding amounts will be secured by The Saint Mary and all subsequent improvements. The construction loan agreement and related document contain affirmative and negative covenants usual and customary for loan agreements of this nature. Stratus may extend the maturity of this loan for up to two additional 12 -month periods if certain conditions are met, including debt service coverage ratio thresholds. As of June 30, 2018 , no amounts were drawn on The Saint Mary construction loan. For a description of Stratus' other debt, refer to Note 6 in the Stratus 2017 Form 10-K. Interest Expense and Capitalization. Interest costs (before capitalized interest) totaled $3.8 million in second-quarter 2018 , $2.9 million in second-quarter 2017 , $7.2 million for the first six months of 2018 and $6.3 million for the first six months of 2017 . Stratus' capitalized interest costs totaled $2.0 million in second-quarter 2018 , $1.4 million in second-quarter 2017 , $3.9 million for the first six months of 2018 and $2.8 million for the first six months of 2017 , primarily related to development activities at Barton Creek. Equity. Stratus' Comerica Bank credit facility requires the bank's prior written consent to pay a dividend on Stratus' common stock. On March 15, 2017 , Stratus' Board of Directors (the Board), after receiving written consent from Comerica Bank, declared a special cash dividend of $1.00 per share ( $8.1 million ), which was paid on April 18, 2017 , to stockholders of record on March 31, 2017 . The special cash dividend was declared after the Board’s consideration of the results of the sale of The Oaks at Lakeway.

Income Tax Disclosure [Abstract]
Income Taxes [Text Block]	INCOME TAXES Stratus’ accounting policy for and other information regarding its income taxes is further described in Notes 1 and 7 in the Stratus 2017 Form 10-K. Stratus had deferred tax assets (net of deferred tax liabilities) totaling $12.1 million at June 30, 2018 , and $11.5 million at December 31, 2017 . Stratus’ income tax benefit for the first six months of 2018 includes a deferred tax benefit of $0.7 million , partly offset by income tax expense of $0.2 million . 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. The difference between Stratus' consolidated effective income tax rate for the first six months of 2018 and the first six months of 2017 , and the U.S. Federal statutory income tax rate of 21 percent for 2018 and 35 percent for 2017, was primarily attributable to the Texas state margin tax.

Segment Reporting [Abstract]
Business Segments [Text Block]	BUSINESS SEGMENTS Stratus currently has four operating segments: Real Estate Operations, Leasing Operations, Hotel and Entertainment. The Real Estate Operations segment is comprised of Stratus’ real estate assets (developed, under development and available for development), which consists of its properties in Austin, Texas (the Barton Creek community, including Santal Phase II; the Circle C community, including The Saint Mary; the Lantana community, including Lantana Place; and the condominium units at the W Austin Hotel & Residences); in Lakeway, Texas, located in the greater Austin area (Lakeway); in College Station, Texas (Jones Crossing); and in Magnolia, Texas, located in the greater Houston area (Magnolia). The Leasing Operations segment includes the office and retail space at the W Austin Hotel & Residences, a retail building in Barton Creek Village, Santal Phase I, the West Killeen Market in Killeen, Texas, and portions of the Lantana Place and Jones Crossing projects. The Hotel segment includes the W Austin Hotel located at the W Austin Hotel & Residences in downtown Austin, Texas. The Entertainment segment includes ACL Live, a live music and entertainment venue and production studio at the W Austin Hotel & Residences. 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, including 3TEN ACL Live, which opened in March 2016 on the site of the W Austin Hotel & Residences. Stratus uses operating income or loss to measure the performance of each segment. General and administrative expenses, which primarily consist of employee salaries, wages and other costs, are managed on a consolidated basis and are not allocated to Stratus' operating segments. The following segment information reflects management determinations that may not be indicative of what the actual financial performance of each segment would be if it were an independent entity.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements and Changes in Accounting Principles [Text Block]	NEW ACCOUNTING STANDARDS Revenue Recognition. In May 2014, the Financial Accounting Standards Board (FASB) issued a new Accounting Standards Update (ASU) related to revenue recognition. Stratus adopted this standard effective January 1, 2018, under the modified retrospective approach applied to contracts that remain in force at the adoption date. The adoption of this standard did not result in any changes to Stratus' revenue recognition policies or processes (refer to Note 1 of Stratus' 2017 Form 10-K for disclosure of Stratus' revenue recognition policy) except as follows: Revenue or gains on sales of real estate are recognized when control of the asset has been transferred to the buyer if collection of substantially all of the consideration to which Stratus will be entitled is probable and Stratus has satisfied all other performance obligations under the contract. Consideration is allocated among multiple performance obligations or distinct nonfinancial assets to be transferred to the buyer based on relative fair value. Financial Instruments. In January 2016, FASB issued an ASU that amends the guidance on the classification and measurement of financial instruments. This ASU makes limited changes to prior guidance and amends certain disclosure requirements. Stratus adopted this ASU effective January 1, 2018, and the adoption did not have a material impact on its financial statements. Leases. In February 2016, FASB issued an ASU that will require lessees to recognize most leases on the balance sheet. This ASU allows lessees to make an accounting policy election to not recognize a lease asset and liability for leases with a term of 12 months or less and do not have a purchase option that is expected to be exercised. For public entities, this ASU is effective for interim and annual reporting periods beginning after December 15, 2018, with early adoption permitted. In July 2018, FASB issued a practical expedient allowing for entities to apply the provisions of the updated lease guidance at the January 1, 2019, effective date, without adjusting the comparative periods presented. Stratus continues to review the impact of the new guidance on its financial reporting and disclosures, including the impact of the College Station ground lease. Statement of Cash Flows: Restricted Cash. In November 2016, FASB issued an ASU that changes the classification and presentation of restricted cash and restricted cash equivalents on the statement of cash flows. The ASU requires that a statement of cash flows include the change during the period in the total of cash, cash equivalents and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. Stratus adopted this ASU effective January 1, 2018, and adjusted its consolidated statement of cash flows for the six months ended June 30, 2017 , to include restricted cash (Stratus has no restricted cash equivalents) with cash and cash equivalents. The impact of adopting this ASU for the six months ended June 30, 2017 , follows (in millions): Previously Reported Impact of Adoption Current Presentation Net increase (decrease) in cash, cash equivalents and restricted cash $ 1,208 $ (1,295 ) $ (87 ) Cash, cash equivalents and restricted cash at beginning of year 13,597 11,892 25,489 Cash, cash equivalents and restricted cash at end of period $ 14,805 $ 10,597 $ 25,402

Subsequent Events [Abstract]
Subsequent Events [Text Block]	SUBSEQUENT EVENTS On July 11, 2018, Stratus' Compensation Committee (the Committee) of the Board unanimously adopted the Stratus Profit Participation Incentive Plan to enable Stratus to attract and retain highly qualified employees who will contribute to Stratus’ long-term success by providing award opportunities that align the interests of Stratus’ executives, other employees and consultants designated by the Committee with those of Stratus’ stockholders. On August 6, 2018, Stratus purchased a 54-acre tract of land in Kingwood, Texas to be developed as Kingwood Place. See Note 3 for further discussion. Stratus evaluated events after June 30, 2018 , 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.
