Organization Consolidation And Presentation Of Financial Statements [Abstract]
Organization	1. ORGANIZATION Organization . Presidio Property Trust, Inc. (formerly known as NetREIT, Inc.) (the “Company”) is incorporated in the State of Maryland and operates as a self-administered real estate investment trust (“REIT”) under the Internal Revenue Code of 1986, as amended (the “Code”). The Company’s portfolio includes the following properties: • Fifteen office buildings and two industrial properties (“Office/Industrial Properties”) which total approximately 1,464,000 rentable square feet, • Four retail shopping centers and one mixed use property (“Retail Properties”) which total approximately 228,000 rentable square feet, and • One hundred thirty-nine Model Homes owned by four affiliated limited partnerships and one limited liability company (“Residential Properties”). The Company operates in the following partnerships during the periods covered by these condensed consolidated financial statements: • The Company is the sole General Partner in two limited partnerships (NetREIT Palm Self-Storage LP and NetREIT Casa Grande LP), all with ownership in real estate income producing properties. The Company refers to these entities collectively, as the “NetREIT Partnerships”. In June 2016, the Company purchased the 5.99% outside interest in NetREIT Garden Gateway LP. • The Company is the general and limited partner in four partnerships that purchase and lease back Model Homes from developers (“Dubose Model Home Investors #201, LP”, “Dubose Model Homes Investors #202, LP”, “Dubose Model Homes Investors #203, LP” and “NetREIT Dubose Model Home REIT, LP”). The Company refers to these entities collectively, as the “Model Home Partnerships”. The Company has determined that the entities described above, where it owns less than 100%, should be included in the Company’s consolidated financial statements as the Company directs their activities and has control of these limited partnerships. The Company has elected to be taxed as a REIT under Sections 856 through 860 of the Code, for federal income tax purposes. To qualify as a REIT, the Company must distribute annually at least 90% of adjusted taxable income, as defined in the Code, to its stockholders and satisfy certain other organizational and operating requirements. As a REIT, no provision is made for federal income taxes on income resulting from those sales of real estate investments which have or will be distributed to stockholders within the prescribed limits. However, taxes are provided for those gains which are not anticipated to be distributed to stockholders unless such gains are deferred pursuant to Section 1031. In addition, the Company is subject to a federal excise tax which equals 4% of the excess, if any, of 85% of the Company’s ordinary income plus 95% of the Company’s capital gain net income over cash distributions, as defined. The Company believes that it has met all of the REIT distribution and technical requirements for the three and nine months ended September 30, 2017 and 2016. Earnings and profits that determine the taxability of distributions to stockholders differ from net income reported for financial reporting purposes due to differences in estimated useful lives and tax deprecation methods used to compute the carrying value (basis) on the investments in properties for tax purposes, among other things. During the nine months ended September 30, 2017 and 2016, all distributions paid were considered return of capital to the stockholders as we reported a taxable net loss during the period. The Company has concluded that there are no significant uncertain tax positions requiring recognition in its financial statements. Neither the Company nor its subsidiaries have been assessed any significant interest or penalties for tax positions by any major tax jurisdictions.

Accounting Policies [Abstract]
Significant Accounting Policies	2. SIGNIFICANT ACCOUNTING POLICIES There have been no significant changes to the Company’s accounting policies since it filed its audited financial statements in its Annual Report on Form 10-K for the year ended December 31, 2016. For further information about the Company’s accounting policies, refer to the Company’s consolidated financial statements and notes thereto for the year ended December 31, 2016 included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) on March 17, 2017 and amended on April 20, 2017. Basis of Presentation. The accompanying condensed consolidated financial statements have been prepared by the Company's management in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial statement and the instructions to Form 10-Q and Article 8 of Regulation S-X. Certain information and footnote disclosures required for annual consolidated financial statements have been condensed or excluded pursuant to rules and regulations of the SEC. In the opinion of management, the accompanying condensed consolidated financial statements reflect all adjustments of a normal and recurring nature that are considered necessary for a fair presentation of our financial position, results of our operations, and cash flows as of and for the nine months ended September 30, 2017 and 2016, respectively. However, the results of operations for the interim periods are not necessarily indicative of the results that may be expected for the year ending December 31, 2017. These condensed consolidated financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2016. The condensed consolidated balance sheet at year ended December 31, 2016 has been derived from the audited consolidated financial statements included in the Form 10-K filed with the SEC on March 17, 2017 and amended on April 20, 2017. Principles of Consolidation. The accompanying condensed consolidated financial statements include the accounts of the Company and its direct and indirect wholly-owned subsidiaries and entities the Company controls or of which it is the primary beneficiary. All significant intercompany balances and transactions have been eliminated in consolidation. Use of Estimates. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. Significant estimates include the allocation of purchase price paid for property acquisitions between land, building and intangible assets acquired including their useful lives; valuation of long-lived assets, and the allowance for doubtful accounts, which is based on an evaluation of the tenants’ ability to pay. Actual results may differ from those estimates. Real Estate Held for Sale. Real estate held for sale during the current period is classified as “real estate held for sale” for all prior periods presented in the accompanying condensed consolidated financial statements. Mortgage notes payable related to the real estate held for sale during the current period is classified as “notes payable related to real estate held for sale” for all prior periods presented in the accompanying condensed consolidated financial statements. Asset Impairments. We review the carrying value of each of our real estate properties quarterly to determine if circumstances indicate an impairment in the carrying value of these investments exists. During the nine months ended September 30, 2017, management did not believe any impairment reserve was required. Reclassifications. Certain reclassifications have been made to the previously presented consolidated financial statements and condensed consolidated financial statements to conform to the current period presentation. These reclassifications had no effect on previously reported results of consolidated operations or equity. Subsequent Events. We evaluate subsequent events up until the date the consolidated financial statements are issued. Recently Issued Accounting Pronouncements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) (“ASU No. 2016-02”). The amendments in ASU No. 2016 -02 changes the existing accounting standards for lease accounting, including requiring lessees to recognize most leases on their balance sheets and making targeted changes to lessor accounting. ASU No. 2016-02 is effective for annual periods beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption of ASU No. 2016-02 as of its issuance is permitted. The new leases standard requires a modified retrospective transition approach for all leases existing at, or entered into after, the date of initial application, with an option to use certain transition relief. The Company is currently evaluating the impact of adopting the new leases standard on its consolidated financial statements. In November 2016, the FASB issued Accounting Standards Update (“ASU”) 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash”. This update requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. As a result, 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. The new standard is effective for annual reporting periods beginning after December 15, 2017 with early adoption permitted. The amendments should be applied using a retrospective transition method to each period presented. The Company is still evaluating the provisions of ASU 2016-18 and its impact on the consolidated statement of cash flows.

Series B Mandatorily Redeemable Preferred Stock	8. SERIES B MANDATORILY REDEEMABLE PREFERRED STOCK In August 2014, the Company closed on a private placement offering of its mandatorily redeemable Series B Preferred Stock. The financing, was funded in installments and completed on December 24, 2015. As of December 31, 2015, the Company had issued 35,000 shares of its Series B Preferred Stock. The Company has classified the Series B Preferred Stock as a liability in accordance with ASC Topic No. 480, “ Distinguishing Liabilities from Equity The Series B preferred stock has a $0.01 par value and a $1,000 liquidation preference.

Stockholders Equity Note [Abstract]
Stockholders' Equity	9. STOCKHOLDERS' EQUITY Preferred Stock. The Company is authorized to issue up to 8,990,000 shares of preferred stock (the “Preferred Stock”). The Preferred Stock may be issued from time to time in one or more series. The Board of Directors is authorized to fix the number of shares of any series of the Preferred Stock, to determine the designation of any such series, and to determine or alter the rights granted to or imposed upon any wholly unissued series of preferred stock including the dividend rights, dividend rate, conversion rights, voting rights, redemption rights (including sinking fund provisions), redemption price, and liquidation preference. Common Stock. The Company is authorized to issue up to 100,000,000 shares of Series A Common Stock (“Common Stock”) $0.01 par value and 1,000 shares of Series B Common Stock $0.01 par value. The Common Stock and the Series B Common Stock have identical rights, preferences, terms and conditions except that the Series B Common Stockholders are not entitled to receive any portion of Company assets in the event of Company liquidation. There have been no Series B Common Stock shares issued. Each share of Common Stock entitles the holder to one vote. The Common Stock is not subject to redemption and it does not have any preference, conversion, exchange or pre-emptive rights. The articles of incorporation contain a restriction on ownership of the Common Stock that prevents one person from owning more than 9.8% of the outstanding shares of common stock. In October 2006, the Company commenced a private placement offering of its common stock. Through December 31, 2011 when the offering was closed, the Company conducted a self-underwritten private placement offering and sale of 20,000,000 shares of its common stock at a price of $10 per share. This offering was made only to accredited investors (and up to thirty-five non-accredited investors) pursuant to an exemption from registration provided by Section 4(2) and Rule 506 of Regulation D under the Securities Act of 1933, as amended. No public or private market currently exists for the securities sold under this offering. Cash Dividends. In September 2017, we filed a registration statement relating to our proposed initial public offering. In light of the proposed offering, we suspended the payment of dividends corresponding to the three months ended September 30, 2017. During the nine months ended September 30, 2017 and 2016 the Company paid cash dividends, net of reinvested stock dividends, of approximately $3,621,000 and $3,348,000, respectively, or at a rate of $0.10 per share on a quarterly basis. As the Company expects to report net taxable losses for the year ended December 31, 2017, and on a cumulative basis, the cash dividends paid are expected to be a return of capital to the stockholders rather than a distribution of earnings. Dividend Reinvestment Plan. The Company has adopted a distribution reinvestment plan that allows stockholders to have dividends and other distributions otherwise distributable to them invested in additional shares of Company common stock. The Company has registered 3,000,000 shares of common stock pursuant to the dividend reinvestment plan. The dividend reinvestment plan became effective on January 23, 2012. The purchase price per share is 95% of the price the Company was formerly selling its shares or $9.50 per share. No sales commission or dealer manager fee will be paid on shares sold through the dividend reinvestment plan. The Company may amend, suspend or terminate the Plan at any time. Any such amendment, suspension or termination will be effective upon a designated dividend record date and notice of such amendment, suspension or termination will be sent to all Participants at least thirty (30) days prior to such record date. As of September 30, 2017 approximately $17.4 million or approximately 1,834,147 shares of common stock have been issued under the dividend reinvestment plan to date.

Segments

Segment Reporting [Abstract]
Segments	11. SEGMENTS The Company’s reportable segments consist of three types of commercial real estate properties for which the Company’s decision-makers internally evaluate operating performance and financial results: Office/Industrial Properties, Residential Properties and Retail Properties. The Company also has certain corporate level activities including accounting, finance, legal administration and management information systems which are not considered separate operating segments. The accounting policies of the reportable segments are the same as those described in Note 2. There is no inter segment activity. The Company evaluates the performance of its segments based upon net operating income (“NOI”), which is a non-GAAP supplemental financial measure. The Company defines NOI for its segments as operating revenues (rental income, tenant reimbursements and other operating income) less property and related expenses (property operating expenses, real estate taxes, insurance, asset management fees, impairments and provision for bad debt). NOI excludes certain items that are not considered to be controllable in connection with the management of an asset such as non-property income and expenses, depreciation and amortization, real estate acquisition fees and expenses and corporate general and administrative expenses. The Company uses NOI to evaluate the operating performance of the Company’s real estate investments and to make decisions about resource allocations. The following tables reconcile the Company’s segment activity to its results of operations and financial position as of and for the three and nine months ended September 30, 2017 and 2016.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation. The accompanying condensed consolidated financial statements have been prepared by the Company's management in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial statement and the instructions to Form 10-Q and Article 8 of Regulation S-X. Certain information and footnote disclosures required for annual consolidated financial statements have been condensed or excluded pursuant to rules and regulations of the SEC. In the opinion of management, the accompanying condensed consolidated financial statements reflect all adjustments of a normal and recurring nature that are considered necessary for a fair presentation of our financial position, results of our operations, and cash flows as of and for the nine months ended September 30, 2017 and 2016, respectively. However, the results of operations for the interim periods are not necessarily indicative of the results that may be expected for the year ending December 31, 2017. These condensed consolidated financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2016. The condensed consolidated balance sheet at year ended December 31, 2016 has been derived from the audited consolidated financial statements included in the Form 10-K filed with the SEC on March 17, 2017 and amended on April 20, 2017.
Principles of Consolidation	Principles of Consolidation. The accompanying condensed consolidated financial statements include the accounts of the Company and its direct and indirect wholly-owned subsidiaries and entities the Company controls or of which it is the primary beneficiary. All significant intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. Significant estimates include the allocation of purchase price paid for property acquisitions between land, building and intangible assets acquired including their useful lives; valuation of long-lived assets, and the allowance for doubtful accounts, which is based on an evaluation of the tenants’ ability to pay. Actual results may differ from those estimates.
Real Estate Held for Sale	Real Estate Held for Sale. Real estate held for sale during the current period is classified as “real estate held for sale” for all prior periods presented in the accompanying condensed consolidated financial statements. Mortgage notes payable related to the real estate held for sale during the current period is classified as “notes payable related to real estate held for sale” for all prior periods presented in the accompanying condensed consolidated financial statements.
Asset Impairments	Asset Impairments. We review the carrying value of each of our real estate properties quarterly to determine if circumstances indicate an impairment in the carrying value of these investments exists. During the nine months ended September 30, 2017, management did not believe any impairment reserve was required.
Reclassifications	Reclassifications. Certain reclassifications have been made to the previously presented consolidated financial statements and condensed consolidated financial statements to conform to the current period presentation. These reclassifications had no effect on previously reported results of consolidated operations or equity.
Subsequent Events	Subsequent Events. We evaluate subsequent events up until the date the consolidated financial statements are issued.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) (“ASU No. 2016-02”). The amendments in ASU No. 2016 -02 changes the existing accounting standards for lease accounting, including requiring lessees to recognize most leases on their balance sheets and making targeted changes to lessor accounting. ASU No. 2016-02 is effective for annual periods beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption of ASU No. 2016-02 as of its issuance is permitted. The new leases standard requires a modified retrospective transition approach for all leases existing at, or entered into after, the date of initial application, with an option to use certain transition relief. The Company is currently evaluating the impact of adopting the new leases standard on its consolidated financial statements. In November 2016, the FASB issued Accounting Standards Update (“ASU”) 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash”. This update requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. As a result, 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. The new standard is effective for annual reporting periods beginning after December 15, 2017 with early adoption permitted. The amendments should be applied using a retrospective transition method to each period presented. The Company is still evaluating the provisions of ASU 2016-18 and its impact on the consolidated statement of cash flows.
