| Accounting Policies [Abstract] | |
| Basis of Accounting, Policy [Policy Text Block] |
Basis of presentation. Our consolidated financial statements and accompanying notes are prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”).
As required under U.S. GAAP, we deconsolidated our Pillarstone OP, Whitestone CP Woodland Ph. 2, LLC, Whitestone Industrial-Office, LLC and Whitestone Offices, LLC subsidiaries from our consolidated financial statements effective with their bankruptcy filings on March 4, 2024. We previously deconsolidated Whitestone Uptown Tower, LLC effective with its bankruptcy filing on December 1, 2023.
The financial condition and results of operations of the bankrupt subsidiaries are no longer presented in our consolidated financial statements after the effective date of their filings. For periods before the deconsolidation, the Company’s consolidated financial condition and results of operations include those of the deconsolidated subsidiaries as discontinued operations.
Noncontrolling interest in the accompanying consolidated financial statements represents the share of equity and earnings of Pillarstone OP allocable to holders of partnership interests other than us.

| Use of Estimates, Policy [Policy Text Block] |
Use of estimates. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates include the estimated fair value of receivable from Pillarstone OP, and deferred taxes and the related valuation allowance for deferred taxes.
|
| Cash and Cash Equivalents, Policy [Policy Text Block] |
Cash and cash equivalents. We consider all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents.
|
| Property, Plant and Equipment, Impairment [Policy Text Block] |
Impairment. We review long-lived assets for impairment at least annually or whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable through operations. We determine whether an impairment in value has occurred by comparing the estimated future cash flows (undiscounted and without interest charges), including the estimated residual value of the asset, with the carrying cost of the asset. If impairment is indicated, a loss will be recorded for the amount by which the carrying value of the property exceeds its fair value. There was no impairment of our long-lived assets during the periods presented.
|
| Share-Based Payment Arrangement [Policy Text Block] |
Stock-based compensation. We account for employee stock-based compensation using the fair value method. Compensation cost for equity incentive awards is based on the fair value of the equity instrument generally on the date of grant and is recognized over the requisite service period. Forfeitures are recognized as they occur. The Company uses the Black-Scholes option pricing model to estimate the fair value of option awards. The Black-Scholes option pricing model requires the input of highly subjective assumptions including the expected stock price volatility of the Company’s common stock, the risk-free interest rate at the date of grant, the expected vesting term of the grant, expected dividends, and an assumption related to forfeitures of such grants. Changes in these subjective input assumptions can materially affect the estimated fair value of the option awards.
|
| Income Tax, Policy [Policy Text Block] |
Income taxes. We have not elected to be taxed as a REIT for federal income tax purposes. As such, we account for income taxes using the asset and liability method under which deferred tax assets and liabilities are determined based on differences between the financial reporting and tax bases of assets and liabilities using enacted tax rates in effect for the period in which the differences are expected to affect taxable income. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. We are also subject to certain state and local income, excise and franchise taxes. The provision for state and local taxes has been reflected in the provision for income taxes in the consolidated statements of operations and has not been separately stated due to its insignificance.
We file tax returns federally and in the state of Texas. Our returns for periods prior to are no longer subject to examination by tax authorities in these jurisdictions. We recognize the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit. If a tax position meets the “more likely than not” recognition criteria, accounting guidance requires the tax position be measured at the largest amount of benefit greater than 50% likely of being realized upon ultimate settlement. We record income tax related interest and penalties, if any, as a component in the provision for income tax expense.
|
| Earnings Per Share, Policy [Policy Text Block] |
Earnings (loss) per share – Basic earnings (loss) per share amounts are calculated by dividing income (loss) available to common shareholders by the weighted average number of common shares outstanding. Diluted earnings (loss) per share amounts are calculated by dividing income (loss) available to common shareholders by the weighted average number of common shares and common stock equivalents outstanding which are not antidilutive. Common stock equivalents represent shares issuable upon the assumed conversion of outstanding convertible notes and preferred shares and the assumed exercise of outstanding options.
|
| Fair Value Measurement, Policy [Policy Text Block] |
Fair Value Measurements. We measure the fair value of financial instruments based on assumptions that market participants would use in pricing the asset or liability. As a basis for considering market participant assumptions in fair value measurements, a fair value hierarchy distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity and the reporting entity’s own assumptions about market participant assumptions. In accordance with the fair value hierarchy, Level 1 assets/liabilities are valued based on quoted prices for identical instruments in active markets, Level 2 assets/liabilities are valued based on quoted prices in active markets for similar instruments, on quoted prices in less active or inactive markets or on other “observable” market inputs, and Level 3 assets/liabilities are valued based significantly on “unobservable” market inputs.
Our financial instruments consist primarily of cash, cash equivalents, accounts receivable, accounts and notes payable. The carrying value of cash, cash equivalents, accounts receivable and accounts payable are representative of their respective fair values due to their short-term nature. The fair value of our convertible debt instrument, which consisted of a fixed rate secured note, approximated its carrying amounts due to the near-term maturity of the instrument.
|
| Concentration Risk, Credit Risk, Policy [Policy Text Block] |
Concentration of Risk. We maintain cash accounts in major U.S. financial institutions. The terms of these deposits are on demand to minimize risk. The balances of these accounts sometimes exceed the federally insured limits, although no losses have been incurred in connection with these deposits.

| New Accounting Pronouncements, Policy [Policy Text Block] |
Recent accounting pronouncements. In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”). The amendments in ASU 2023-07 require incremental disclosures related to a public entity’s reportable segments and increase the frequency with which most segment disclosures are made. Incremental disclosures required by the ASU include significant segment expenses regularly provided to the chief operating decision maker (“CODM”) and included within the segment’s measure of profit or loss, the title and position of the CODM and an explanation how the CODM uses the reported measure of a segment’s profit or loss to assess performance and allocate resources, and the amount and composition of other segment items necessary to reconcile segment revenue, significant expenses, and the reported measure of profit or loss. The ASU also expands interim disclosure requirements such that nearly all annual quantitative segment disclosures will be made on an interim basis. Lastly, ASU 2023-07 requires that entities with a single reportable segment provide all segment disclosures that are not evident from the primary financial statements, including significant segment expenses, consistent with the approach used by management to evaluate performance, which affects the Company’s disclosures. We implemented ASU 2023-07 effective with the Company’s 2024 annual report, and included required disclosures herein.
In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”). The amendments in ASU 2023-09 require reporting entities to disclose annual income taxes paid, net of refunds, disaggregated by federal, state, and foreign taxes and to provide additional disaggregated information for individual jurisdictions that equal or exceed 5% of total income taxes paid, net of refunds. ASU 2023-09 also requires public business entities to disclose additional categories of information about federal, state, and foreign income taxes in their annual rate reconciliation table and provide more information about some categories if the quantitative threshold is met. The ASU will also require disclosure of amounts and percentages in the annual rate reconciliation table, rather than amounts or percentages, and will eliminate certain existing disclosure requirements related to uncertain tax positions and unrecognized deferred tax liabilities. ASU 2023-09 is effective starting with the Company’s 2025 annual financial statements and may be applied prospectively to only the income tax disclosures provided for 2025 or retrospectively by providing revised disclosures for all periods presented. Early adoption is permitted. The Company is currently evaluating the impact of the ASU; however, incremental disclosures will likely be provided on a prospective basis in the Company’s 2025 annual financial statements upon adoption.
In November 2024, the FASB issued ASU 2024-03, Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses (“ASU 2024-03”). The amendments in ASU 2024-03 require public business entities to disclose in the notes to the financial statements, among other things, specific information about certain costs and expenses including purchases of inventory, employee compensation, and depreciation, amortization, and depletion expenses for each caption on the income statement where such expenses are included. ASU 2024-03 is effective starting with the Company’s 2027 annual financial statements and on a quarterly basis thereafter. Early adoption is permitted, and the amendments may be applied prospectively to reporting periods after the effective date or retrospectively to all periods presented in the financial statements. The Company is currently evaluating the extent to which its disclosures will be affected by the ASU.
