Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	1. The Company Gyrodyne, LLC (“Gyrodyne”, the “Company” or the “Registrant”) is a limited liability company formed under the laws of the State of New York whose primary business is the management of a geographically diverse portfolio of medical office and industrial properties and the pursuit of entitlement/re-zoning in properties located in Suffolk and Westchester Counties, New York. Substantially all of our developed properties are subject to leases in which the tenant reimburses the Company for a portion, all of or substantially all of the costs and/or cost increases for utilities, insurance, repairs, maintenance and real estate taxes. Certain leases provide that the Company is responsible for certain operating expenses.

Gyrodyne ’s strategy is to enhance the value of Flowerfield and Cortlandt Manor by pursuing possible entitlement and/or zoning opportunities, which the Board believes will improve the chances of obtaining better values for such properties. The value of the real estate reported in the Statements of Net Assets as of December 31, 2017, 2016 not may no may not first The Company is making tenant improvements at Flowerfield to convert certain existing industrial space into office space to meet our expanding relationship with Stony Brook University, which the Company believes will enhance the value of the property as a whole by improving the building space and drawing a high quality long-term tenant. It would also increase the synergy with the University and allow for a portion of the trip generation from this office space to be accommodated using the internal access point between the properties. The Company believes positioning the industrial park buildings to mitigate traffic impact on the local roads will maximize the entitlements and related value it is pursuing on the Flowerfield property. The planned tenant improvements for leases signed in the first $1,000,000 Sales of properties by Gyrodyne could take the form of individual sales of assets, as has been our recent experience in Port Jefferson, sales of groups of assets, a single sale of all or substantially all of the assets or some other form of sale.

Uncertainties as to the precise value of our non-cash assets, which exclude any estimated additional value achievable from the costs incurred to pursue the maximum value on Flowerfield and Cortlandt Manor through certain land entitlement efforts (inclusive of the pursuit of special permits and or zone changes) and the ultimate amount of our liabilities make it impracticable to predict the aggregate net value ultimately distributable to shareholders in a liquidation. Land entitlement costs, claims, liabilities and expenses from operations, including operating costs, salaries, income taxes, payroll and local taxes, legal, accounting and consulting fees and miscellaneous office expenses, will continue to be incurred during our liquidation process, which includes certain enhancement efforts. Excluding the value that may ’s business plan will reduce the amount of assets available for ultimate distribution to shareholders, and, while a precise estimate of those expenses cannot currently be made, management and our Board believe that available cash and amounts received on the sale of assets will be adequate to provide for our obligations, liabilities, expenses and claims (including contingent liabilities) and to make cash distributions to shareholders.

Significant Accounting Policies [Text Block]	3. Summary of Significant Accounting Policies Gyrodyne is pursuing the opportunistic disposition of certain properties and the enhancement of the value of the Flowerfield and Cortlandt Manor properties, by pursuing various zoning/entitlement opportunities, which the Gyrodyne Board believes will improve the chances of obtaining better values for such properties. Gyrodyne intends to dissolve after it completes the disposition of all of its real property assets, applies the proceeds of such dispositions first September 1, 2015 205 30, Gyrodyne’s Amended and Restated Limited Liability Company Agreement the Board has the ability to sell all the Company’s assets without further approval. As a result, liquidation is “imminent” in accordance with the guidance provided in ASC 205 30. Principles of consolidation - The consolidated financial statements include the accounts of Gyrodyne and all subsidiaries. All consolidated subsidiaries are wholly-owned. All inter-company balances and transactions have been eliminated. Basis of Presentation - Liquidation Basis of Accounting – Under the liquidation basis of accounting the consolidated balance sheet, consolidated statement of operations, statement of equity, consolidated statement of comprehensive income and the consolidated statement of cash flows are no Under the liquidation basis of accounting, all the Company ’s assets have been stated at their estimated net realizable value, or liquidation value, (which represents the estimated amount of cash that Gyrodyne will collect on the disposal of assets as it carries out the plan of liquidation), which is based on current contracts, estimates and other indications of sales value (predicated on current values). All liabilities of the Company, including those estimated costs associated with implementing the plan of liquidation, have been stated at their estimated settlement amounts. These amounts are presented in the accompanying statements of net assets. These estimates are periodically reviewed and adjusted as appropriate. There can be no not may may 2019. two not may no The Company is pursuing value associated with the highest and best use for Flowerfield and the Cortlandt Medical Center. The actual costs of achieving such values may The Company ’s assumptions and estimates (including the sales proceeds of all its real estate holdings, selling costs, retention bonus payments, rental revenues, rental expenses, capital expenditures, land entitlement/re-zoning costs, general and administrative fees, director and officer liability and reimbursement, post liquidation insurance tail coverage policy and final liquidation costs) are based on completing the liquidation by the end of 2019. Management Estimates – In preparing the consolidated financial statements in conformity with U.S. Generally Accepted Accounting Principles (“GAAP”) and the liquidation basis of accounting, management is required to make estimates and assumptions that affect the reported amounts of assets, including net assets in liquidation, and liabilities and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amounts of receipts and expenditures for the reporting period. Actual results could differ from those estimates. The most significant estimates are the estimates of the net realizable value of our real estate, the estimated costs/time to pursue entitlements/change of zone and the related timeline to complete the liquidation. Allowance for doubtful accounts – Rent receivable is carried at net realizable value. Management makes estimates of the collectability of rents receivable. Management specifically analyzes receivables and historical bad debts, customer concentrations, customer credit-worthiness, current economic trends and changes in customer payment terms when evaluating the adequacy of the allowance for doubtful accounts. Cash equivalents - The Company considers all certificates of deposits, money market funds, treasury securities and other highly liquid debt instruments purchased with short-term maturities to be cash equivalents. Income taxes - The Company follows the guidance of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification, Accounting for Uncertainty in Income Taxes. This guidance, among other things, creates a two one not two not no not not no 2014, 2015, 2016.

As a result, the Company follows the guidance of FASB Accounting Standards Codification, Fair Value Measurements and Disclosures to determine the fair value of financial and non-financial instruments. The guidance defines fair value, establishes a hierarchy framework for measuring fair value and expands disclosures related to the fair value. The guidance establishes a hierarchy breaking down observable and unobservable inputs into three 1 2 not 3 no New accounting pronouncements - Management has evaluated the impact of newly issued accounting pronouncements, whether effective or not December 31, 2017, not

Fair Value Disclosures [Text Block]	17. Fair Value of Financial Instruments Assets and Liabilities Measured at Fair-Value – The Company believes the concepts for determining net realizable value are consistent with the guidance for measuring fair value. As a result, the Company follows authoritative guidance on fair value measurements, which defines fair-value, establishes a framework for measuring fair-value, and expands disclosures about fair-value measurements. The guidance applies to reported balances that are required or permitted to be measured at fair-value under existing accounting pronouncements. The Company follows authoritative guidance on the fair value option for financial assets, which permits companies to choose to measure certain financial instruments and other items at fair-value in order to mitigate volatility in reported earnings caused by measuring related assets and liabilities differently. However, the Company adopted the liquidation basis of accounting, and therefore reports all assets and liabilities at net realizable value. The guidance emphasizes that fair-value is a market-based measurement, not 1 2 ’s own assumptions about market participant assumptions (unobservable inputs classified within Level 3 The following table represents the carrying value at net realizable value of the Company ’s financial assets and liabilities as of December 31, 2016.

The net realizable values of mortgage backed securities originated by US government agencies are based on a pricing model that incorporates coupon type, prepayment speeds and the type of collateral backing the securities. A discount rate is applied to the cash flows in the model to arrive at the net realizable value. Market quotes, current yields, and their spreads to benchmark indices are obtained for each type of security. With this data, a yield curve is derived for each category of mortgage backed securities. Each security is priced by discounting the cash flow stream by the appropriate yield found on the yield curve. As the significant inputs used to derive the value of the mortgage-backed securities are observable market inputs, the net realizable value of these securities is included in the Level 2 February 2017, 100% Fair Value Measurements - The Company adopted the liquidation basis of accounting effective September 1, 2015; The Company estimates the net realizable value of its real estate assets by using income and market valuation techniques.

[1]	In April 2017, the Company extended the term of a master lease with the not-for-profit originally entered into in August 2016. The Company understood that the tenants’ main intent was to sublease the space to artists, on a short-term basis, after which they would transition into their own space leased directly from the Company. Under the master lease, the tenant has the right to sublease the space to one or more artists, on a short-term basis. Under the terms of the master lease, rent is payable by the tenant only to the extent the space is sublet, at the rent amount per square foot payable by the subtenant up to a maximum of $10 per square foot per month. The lease term of 29 months covers 2,130 square feet with a maximum annual and total lease commitment of up to $21,300 and $51,475, respectively. Approximately $3,500 in improvements were provided. Any space not subleased may be used by the tenant rent-free for certain stated art uses, although the tenant is responsible for certain passthrough expenses such as electric and heat. Since rent is only due if the space is sublet, the Company believes the fair value of the space to the extent not sublet reflects a below market lease over the term ending December 31, 2018 of up to $ 51,475 and total commitments including both two-year renewal options of $136,675. The Company believes the lease is in the best interest of the Company as it supports the Company vision to achieve the highest and best use value for Flowerfield. The Company believes establishing an art community at Flowerfield compliments the interests identified in the subdivision application all of which supports maximizing the value of the real estate.

The Company believes establishing an art community at Flowerfield compliments the interests identified in the subdivision application all of which supports maximizing the value of the real estate.
