Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Description of Business	Organization and Description of Business STAG Industrial, Inc. (the “Company”) is an industrial real estate operating company focused on the acquisition, ownership, and operation of single-tenant, industrial properties throughout the United States. The Company was formed as a Maryland corporation and has elected to be treated and intends to continue to qualify as a real estate investment trust (“REIT”) under Sections 856 through 860 of the Internal Revenue Code of 1986, as amended (the “Code”). The Company is structured as an umbrella partnership REIT, commonly called an UPREIT, and owns substantially all of its properties and conducts substantially all of its business through its operating partnership, STAG Industrial Operating Partnership, L.P., a Delaware limited partnership (the “Operating Partnership”). As of December 31, 2020 and 2019, the Company owned a 98.0% and 97.5%, respectively, common equity interest in the Operating Partnership. The Company, through its wholly owned subsidiary, is the sole general partner of the Operating Partnership. As used herein, the “Company” refers to STAG Industrial, Inc. and its consolidated subsidiaries and partnerships, including the Operating Partnership, except where context otherwise requires. As of December 31, 2020, the Company owned 492 buildings in 39 states with approximately 98.2 million rentable square feet (square feet unaudited herein and throughout the Notes), consisting of 410 warehouse/distribution buildings, 74 light manufacturing buildings, and eight flex/office buildings. COVID-19 Pandemic Currently, one of the most significant risks and uncertainties facing the Company and the real estate industry generally is the adverse effect of the ongoing public health crisis of the novel coronavirus disease (“COVID-19”) pandemic. The Company closely monitors the effect of the COVID-19 pandemic on all aspects of its business, including how the pandemic will affect its tenants and business partners. While the Company did not incur significant disruptions from the COVID-19 pandemic during the year ended December 31, 2020, a number of the Company’s tenants requested rent deferral or rent abatement as a result of the pandemic and other tenants may make requests in the future. In response to such requests, the Company entered into rent deferral agreement with certain tenants which resulted in approximately $2.1 million of rent deferrals during the year ended December 31, 2020. The Company will continue to evaluate tenant rent relief requests on an individual basis, considering a number of factors. Not all tenant requests will ultimately result in modified agreements, nor is the Company foregoing its contractual rights under its lease agreements. The Company remains unable to predict the ultimate impact that the pandemic will have on its financial condition, results of operations and cash flows due to numerous uncertainties. The extent to which the COVID-19 pandemic affects the Company’s operations and those of its tenants will depend on future developments, which are highly uncertain and cannot be predicted with confidence, including the scope, severity and duration of the pandemic, the actions taken to contain the pandemic or mitigate its impact, and the direct and indirect economic effects of the pandemic and containment measures, among others.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The Company’s consolidated financial statements include the accounts of the Company, the Operating Partnership and their subsidiaries. Interests in the Operating Partnership not owned by the Company are referred to as “Noncontrolling Common Units.” These Noncontrolling Common Units are held by other limited partners in the form of common units (“Other Common Units”) and long term incentive plan units (“LTIP units”) issued pursuant to the STAG Industrial, Inc. 2011 Equity Incentive Plan, as amended (the “2011 Plan”). All significant intercompany balances and transactions have been eliminated in the consolidation of entities. The financial statements of the Company are presented on a consolidated basis for all periods presented. New Accounting Standards New Accounting Standards Adopted In March 2020, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) 2020-04, Reference Rate Reform (Topic 848) . ASU 2020-04 contains practical expedients for reference rate reform related activities that impact debt, leases, derivatives and other contracts. The guidance in ASU 2020-04 is optional and may be elected over time as reference rate reform activities occur. During the quarter ended March 31, 2020, the Company elected to apply the hedge accounting expedients related to probability and the assessments of effectiveness for future LIBOR-indexed cash flows to assume that the index upon which future hedged transactions will be based matches the index on the corresponding derivatives. Application of these expedients preserves the presentation of derivatives consistent with past presentation. The Company continues to evaluate the impact of the guidance and may apply other elections as applicable as additional changes in the market occur. Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Rental Property and Deferred Leasing Intangibles Rental property is carried at cost less accumulated depreciation and amortization. Expenditures for maintenance and repairs are expensed as incurred. Significant renovations and betterments that extend the economic useful lives of assets are capitalized. The Company capitalizes costs directly and indirectly related to the development, pre-development, redevelopment, or improvement of rental property. Real estate taxes, compensation costs of development personnel, insurance, interest, and other directly related costs during construction periods are capitalized as incurred, with depreciation commencing with the date the property is substantially completed. Such costs begin to be capitalized to the development projects from the point the Company is undergoing the necessary activities to get the development project ready for its intended use and cease when the development projects are substantially completed and held available for occupancy. Interest is capitalized based on actual capital expenditures from the period when development or redevelopment commences until the asset is ready for its intended use, at the weighted average borrowing rate of the Company’s unsecured indebtedness during the period. For properties classified as held for sale, the Company ceases depreciating and amortizing the rental property and values the rental property at the lower of depreciated and amortized cost or fair value less costs to dispose. The Company presents those properties classified as held for sale with any qualifying assets and liabilities associated with those properties as held for sale in the accompanying Consolidated Balance Sheets. Using information available at the time of acquisition, the Company allocates the purchase price of properties acquired based upon the fair value of the assets acquired and liabilities assumed, which generally consist of land, buildings, tenant improvements, mortgage debt assumed, and deferred leasing intangibles, which includes in-place leases, above market and below market leases, and tenant relationships. The process for determining the allocation to these components requires estimates and assumptions, including rental rates, discount rates and exit capitalization rates, and land value per square foot, as well as available market information. The fair value of the tangible assets of an acquired property considers the value of the property as if it were vacant. The portion of the purchase price that is allocated to above and below market leases is valued based on the present value of the difference between prevailing market rates and the in-place rates measured over a period equal to the remaining term of the lease term plus the term of any bargain renewal options. The purchase price is further allocated to in-place lease values and tenant relationships based on the Company’s evaluation of the specific characteristics of each tenant’s lease and its overall relationship with the respective tenant. The above and below market lease values are amortized into rental income over the remaining lease term. The value of in-place lease intangibles and tenant relationships are amortized over the remaining lease term (and expected renewal period of the respective lease for tenant relationships) as increases to depreciation and amortization expense. The remaining lease terms are adjusted for bargain renewal options or assumed exercises of early termination options, as applicable. If a tenant subsequently terminates its lease, any unamortized portion of above and below market leases is accelerated into rental income and the in-place lease value and tenant relationships are accelerated into depreciation and amortization expense over the shortened lease term. The purchase price allocated to deferred leasing intangible assets are included in rental property, net on the accompanying Consolidated Balance Sheets and the purchase price allocated to deferred leasing intangible liabilities are included in deferred leasing intangibles, net on the accompanying Consolidated Balance Sheets under the liabilities section. In determining the fair value of the debt assumed, the Company discounts the spread between the future contractual interest payments and hypothetical future interest payments on mortgage debt based on a current market rate. The associated fair market value debt adjustment is amortized through interest expense over the life of the debt on a basis which approximates the effective interest method. The Company evaluates the carrying value of all tangible and intangible rental property assets and deferred leasing intangible liabilities (collectively, the “property”) held for use for possible impairment when an event or change in circumstance has occurred that indicates their carrying value may not be recoverable. The evaluation includes estimating and reviewing anticipated future undiscounted cash flows to be derived from the property. If such cash flows are less than the property’s carrying value, an impairment charge is recognized to the extent by which the property’s carrying value exceeds the estimated fair value. Estimating future cash flows is highly subjective and is based in part on assumptions regarding anticipated hold period, future occupancy, rental rates, capital requirements, and exit capitalization rates that could differ from actual results. The discount rate used to present value the cash flows for determining fair value is also subjective. Depreciation expense is computed using the straight-line method based on the following estimated useful lives. Description Estimated Useful Life Building 40 Years Building and land improvements (maximum) 20 Years Tenant improvements Shorter of useful life or terms of related lease Fully depreciated or amortized assets or liabilities and the associated accumulated depreciation or amortization are written-off. The Company wrote-off fully depreciated or amortized tenant improvements, deferred leasing intangible assets, and deferred leasing intangible liabilities of approximately $5.0 million, $62.0 million, $2.3 million, respectively, for the year ended December 31, 2020 and approximately $22.8 million, $87.7 million, $5.5 million, respectively, for the year ended December 31, 2019. Leases For leases in which the Company is the lessee, the Company recognizes a right-of-use asset and corresponding lease liability on the accompanying Consolidated Balance Sheets equal to the present value of the fixed lease payments. In determining the operating right-of-use asset and lease liability for the Company’s operating leases, the Company estimates an appropriate incremental borrowing rate on a fully-collateralized basis for the terms of the leases. The Company utilizes a market-based approach to estimate the incremental borrowing rate for each individual lease. Additionally, since the terms of our ground leases are significantly longer than the terms of borrowings available to the Company on a fully-collateralized basis, the estimate of this rate required significant judgment, and considered factors such as yields on outstanding public debt and other market based pricing on longer duration financing instruments. Cash and Cash Equivalents Cash and cash equivalents consist of cash and highly liquid short-term investments with original maturities of three months or less. The Company maintains cash and cash equivalents in United States banking institutions that may exceed amounts insured by the Federal Deposit Insurance Corporation. While the Company monitors the cash balances in its operating accounts, these cash balances could be impacted if the underlying financial institutions fail or are subject to other adverse conditions in the financial markets. To date, the Company has experienced no loss or lack of access to cash in its operating accounts, and mitigates this risk by using nationally recognized banking institutions. Restricted Cash Restricted cash may include tenant security deposits, cash held in escrow for real estate taxes and capital improvements as required in various mortgage note agreements, and cash held by the Company’s transfer agent for preferred stock dividends that are distributed subsequent to period end. Restricted cash may also include cash held by qualified intermediaries to facilitate a like-kind exchange of real estate under Section 1031 of the Code. The following table presents a reconciliation of cash and cash equivalents and restricted cash reported on the accompanying Consolidated Balance Sheets to amounts reported on the accompanying Consolidated Statements of Cash Flows. Reconciliation of cash and cash equivalents and restricted cash (in thousands) December 31, 2020 December 31, 2019 Cash and cash equivalents $ 15,666 $ 9,041 Restricted cash 4,673 2,823 Total cash and cash equivalents and restricted cash $ 20,339 $ 11,864 Deferred Costs Deferred financing fees and debt issuance costs include costs incurred in obtaining debt that are capitalized and are presented as a direct deduction from the carrying amount of the associated debt liability that is not a line-of-credit arrangement on the accompanying Consolidated Balance Sheets. Deferred financing fees and debt issuance costs related to line-of-credit arrangements are presented as an asset in prepaid expenses and other assets on the accompanying Consolidated Balance Sheets. The deferred financing fees and debt issuance costs are amortized through interest expense over the life of the respective loans on a basis which approximates the effective interest method. Any unamortized amounts upon early repayment of debt are written off in the period of repayment as a loss on extinguishment of debt. Fully amortized deferred financing fees and debt issuance costs are written off upon maturity of the underlying debt. Leasing commissions include commissions and other direct and incremental costs incurred to obtain new tenant leases as well as to renew existing tenant leases, and are presented in prepaid expenses and other assets on the accompanying Consolidated Balance Sheets. Leasing commissions are capitalized and amortized over the terms of the related leases (and bargain renewal terms or assumed exercise of early termination options) using the straight-line method. If a lease terminates prior to the expiration of its initial term, any unamortized costs related to the lease are accelerated into amortization expense. Changes in leasing commissions are presented in the cash flows from operating activities section of the accompanying Consolidated Statements of Cash Flows. Goodwill The excess of the cost of an acquired business over the net of the amounts assigned to assets acquired (including identified intangible assets) and liabilities assumed is recorded as goodwill. Goodwill of the Company of approximately $4.9 million represents amounts allocated to the assembled workforce from the acquired management company, and is presented in prepaid expenses and other assets on the accompanying Consolidated Balance Sheets. The Company’s goodwill has an indeterminate life and is not amortized, but is tested for impairment on an annual basis at December 31, or more frequently if events or changes in circumstances indicate that the asset might be impaired. The Company takes a qualitative approach to consider whether an impairment of goodwill exists prior to quantitatively determining the fair value of the reporting unit in step one of the impairment test. The Company has recorded no impairments to goodwill through December 31, 2020. Use of Derivative Financial Instruments The Company records all derivatives on the accompanying Consolidated Balance Sheets at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting, and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. The Company may enter into derivative contracts that are intended to economically hedge certain of its risks, even though hedge accounting does not apply or the Company elects not to apply hedge accounting. In accordance with fair value measurement guidance, the Company made an accounting policy election to measure the credit risk of its derivative financial instruments that are subject to master netting arrangements on a net basis by counterparty portfolio. Credit risk is the risk of failure of the counterparty to perform under the terms of the contract. The Company minimizes the credit risk in its derivative financial instruments by entering into transactions with various high-quality counterparties. The Company’s exposure to credit risk at any point is generally limited to amounts recorded as assets on the accompanying Consolidated Balance Sheets. Fair Value of Financial Instruments Financial instruments include cash and cash equivalents, restricted cash, tenant accounts receivable, interest rate swaps, accounts payable, accrued expenses, unsecured credit facility, unsecured term loans, unsecured notes, and mortgage notes. See Note 4 for the fair value of the Company’s indebtedness. See Note 5 for the fair value of the Company’s interest rate swaps. The Company adopted fair value measurement provisions for its financial instruments recorded at fair value. The guidance establishes a three-tier value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. Offering Costs Underwriting commissions and direct offering costs have been reflected as a reduction of additional paid-in capital on the accompanying Consolidated Balance Sheets and Consolidated Statements of Equity. Indirect costs associated with equity offerings are expensed as incurred and included in general and administrative expenses on the accompanying Consolidated Statements of Operations. Dividends Earnings and profits, which determine the taxability of dividends to stockholders, will differ from income reported for financial reporting purposes due to the differences for federal income tax purposes in the treatment of gains on the sale of real property, revenue and expense recognition, and in the estimated useful lives and basis used to compute depreciation. In addition, the Company’s distributions may include a return of capital. To the extent that the Company makes distributions in excess of its current and accumulated earnings and profits, such distributions would generally be considered a return of capital for federal income tax purposes to the extent of the holder’s adjusted tax basis in its shares. A return of capital may not be taxable. A return of capital has the effect of reducing the holder’s adjusted tax basis in its investment, which may or may not be taxable to the holder. The Company paid approximately $2.4 million ($0.87413 per share) of the 6.625% Series B Cumulative Redeemable Preferred Stock ("Series B Preferred Stock") dividends, of which $0.71493 per share was treated as ordinary income for tax purposes, $0.07521 per share was treated as unrecaptured section 1250 capital gain for tax purposes, and $0.08399 per share was treated as other capital gain for income tax purposes for the year ended December 31, 2018. The Company paid approximately $5.2 million ($1.71875 per share) of the 6.875% Series C Cumulative Redeemable Preferred Stock (“Series C Preferred Stock”) dividends for the year ended December 31, 2020, of which $1.349944 that were treated as ordinary income for tax purposes, $0.100392 per share was treated as unrecaptured section 1250 capital gain for tax purposes, and $0.268414 per share was treated as other capital gain for income tax purposes for the year ended December 31, 2020. The Company paid approximately $5.2 million ($1.71875 per share) of the Series C Preferred Stock dividends for the year ended December 31, 2019, of which $1.71441 that were treated as ordinary income for tax purposes and $0.00434 that were treated as qualified dividends for tax purposes. The Company paid approximately $5.2 million ($1.71875 per share) of the Series C Preferred Stock dividends, of which $1.40573 per share was treated as ordinary income for tax purposes, $0.14789 per share was treated as unrecaptured section 1250 capital gain for tax purposes, and $0.16513 per share was treated as other capital gain for income tax purposes for the year ended December 31, 2018. The following table summarizes the tax treatment of dividends per common share for federal income tax purposes. Year ended December 31, 2020 2019 2018 Federal Income Tax Treatment of Dividends per Common Share Per Share % Per Share % Per Share % Ordinary income $ 1.186648 78.5 % $ 0.888657 62.2 % $ 1.051783 74.1 % Return of capital — — % 0.538270 37.7 % 0.133170 9.4 % Unrecaptured section 1250 capital gain 0.088246 5.9 % — — % 0.110647 7.8 % Other capital gain 0.235943 15.6 % — — % 0.123563 8.7 % Qualified dividend — — % 0.002243 0.1 % — — % Total (1) $ 1.510837 100.0 % $ 1.429170 100.0 % $ 1.419163 100.0 % (1) The December 2018 monthly common stock dividend of $0.118333 per share was included in the stockholder’s 2019 tax year. The December 2019 monthly common stock dividend of $0.119167 per share was included in the stockholder’s 2020 tax year. The December 2020 monthly common stock dividend of $0.12 per share will partially be included in the stockholder's 2020 tax year in the amount of $0.07167 per share, and the remainder will be included in the stockholder's 2021 tax year. Revenue Recognition All current leases are classified as operating leases and rental income is recognized on a straight-line basis over the term of the lease (and expected bargain renewal terms or assumed exercise of early termination options) when collectability is reasonably assured. Differences between rental income earned and amounts due under the lease are charged or credited, as applicable, to accrued rental income. The Company determined that for all leases where the Company is the lessor, that the timing and pattern of transfer of the non-lease components and associated lease components are the same, and that the lease components, if accounted for separately, would be classified as an operating lease. Accordingly, the Company has made an accounting policy election to recognize the combined component in accordance with Topic 842 as rental income on the accompanying Consolidated Statements of Operations. Rental income recognition commences when the tenant takes possession of or controls the physical use of the leased space and the leased space is substantially complete and ready for its intended use. In order to determine whether the leased space is substantially complete and ready for its intended use, the Company determines whether the Company or the tenant own the tenant improvements. When it is determined that the Company is the owner of the tenant improvements, rental income recognition begins when the tenant takes possession of or controls the physical use of the finished space, which is generally when the Company owned tenant improvements are completed. In instances when it is determined that the tenant is the owner of tenant improvements, rental income recognition begins when the tenant takes possession of or controls the physical use of the leased space. When the Company is the owner of tenant improvements or other capital items, the cost to construct the tenant improvements or other capital items, including costs paid for or reimbursed by the tenants, is recorded as capital assets. For these tenant improvements or other capital items, the amount funded by or reimbursed by the tenants are recorded as deferred revenue, which is amortized on a straight-line basis as income over the shorter of the useful life of the capital asset or the term of the related lease. Early lease termination fees are recorded in rental income on a straight-line basis from the notification date of such termination to the then remaining (not the original) lease term, if any, or upon collection if collection is not reasonably assured. The Company evaluates cash basis versus accrual basis of rental income recognition based on the collectability of future lease payments. Gain on the Sales of Rental Property, net The timing of the derecognition of a rental property and the corresponding recognition of gain on the sales of rental property, net is measured by various criteria related to the terms of the sale transaction, and if the Company has lost control of the property and the acquirer has gained control of the property after the transaction. If the derecognition criteria is met, the full gain is recognized. Incentive and Equity-Based Employee Compensation Plans The Company grants equity-based compensation awards to its employees and directors in the form of restricted shares of common stock, LTIP units, and outperformance programs and performance units ( outperformance programs and performance units are collectively, “Performance-based Compensation Plans”) . See Notes 6, 7 and 8 for further discussion of restricted shares of common stock, LTIP units, and Performance-based Compensation Plans , respectively. The Company measures equity-based compensation expense based on the fair value of the awards on the grant date and recognizes the expense ratably over the vesting period, and forfeitures are recognized in the period in which they occur. Related-Party Transactions The Company did not have any related-party transactions during the years ended December 31, 2020, 2019 and 2018. Taxes Federal Income Taxes The Company elected to be taxed as a REIT under the Code commencing with its taxable year ended December 31, 2011 and intends to continue to qualify as a REIT. As a REIT, the Company is generally not subject to corporate level federal income tax on the earnings distributed currently to its stockholders that it derives from its REIT qualifying activities. As a REIT, the Company is required to distribute at least 90% of its REIT taxable income to its stockholders and meet the various other requirements imposed by the Code relating to such matters as operating results, asset holdings, distribution levels and diversity of stock ownership. The Company will not be required to make distributions with respect to income derived from the activities conducted through subsidiaries that the Company elects to treat as taxable REIT subsidiaries (“TRS”) for federal income tax purposes, nor will it have to comply with income, assets, or ownership restrictions inside of the TRS. Certain activities that the Company undertakes must or should be conducted by a TRS, such as performing non-customary services for its tenants and holding assets that it cannot hold directly. A TRS is subject to federal and state income taxes. The Company’s TRS recognized a net income (loss) of approximately $0, $0.3 million and $(0.1) million, for the years ended December 31, 2020, 2019 and 2018, respectively, which has been included on the accompanying Consolidated Statements of Operations. State and Local Income, Excise, and Franchise Tax The Company and certain of its subsidiaries are subject to certain state and local income, excise and franchise taxes. Taxes in the amount of approximately $1.7 million, $1.2 million and $0.9 million have been recorded in other expenses on the accompanying Consolidated Statements of Operations for the years ended December 31, 2020, 2019 and 2018, respectively. Uncertain Tax Positions Tax benefits of uncertain tax positions are recognized only if it is more likely than not that the tax position will be sustained based solely on its technical merits, with the taxing authority having full knowledge of all relevant information. The measurement of a tax benefit for an uncertain tax position that meets the “more likely than not” threshold is based on a cumulative probability model under which the largest amount of tax benefit recognized is the amount with a greater than 50% likelihood of being realized upon ultimate settlement with the taxing authority having full knowledge of all the relevant information. As of December 31, 2020, 2019 and 2018, there were no liabilities for uncertain tax positions. Earnings Per Share The Company uses the two-class method of computing earnings per common share, which is an earnings allocation formula that determines earnings per share for common stock and any participating securities according to dividends declared (whether paid or unpaid) and participation rights in undistributed earnings. Basic net income per common share is computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted net income per common share is computed by dividing net income available to common stockholders by the sum of the weighted average number of common shares outstanding and any dilutive securities for the period. Segment Reporting The Company manages its operations on an aggregated, single segment basis for purposes of assessing performance and making operating decisions and, accordingly, has only one reporting and operating segment. Concentrations of Credit Risk Concentrations of credit risk relevant to the Company may arise when a number of financing arrangements, including revolving credit facilities or derivatives, are entered into with the same lenders or counterparties, and have similar economic features that would cause their inability to meet contractual obligations. The Company mitigates the concentration of credit risk as it relates to financing arrangements by entering into loan syndications with multiple, reputable financial institutions and diversifying its debt counterparties. The Company also reduces exposure by diversifying its derivatives across multiple counterparties who meet established credit and capital guidelines.

The following table summarizes the costs included in interest expense related to the Company’s debt arrangements on the accompanying Consolidated Statement of Operations for the years ended December 31, 2020, 2019 and 2018. Year ended December 31, Costs Included in Interest Expense (in thousands) 2020 2019 2018 Amortization of deferred financing fees and debt issuance costs and fair market value premiums $ 2,922 $ 2,583 $ 2,316 Facility, unused, and other fees $ 1,311 $ 1,513 $ 1,246 2020 Debt Activity On April 29, 2020, the mortgage note associated with the Wells Fargo Bank, National Association CMBS Loan was partially defeased in the amount of approximately $1.0 million in connection with the sale of the Johnstown, NY property, which had served as partial collateral for the mortgage note. The associated defeasance fees and unamortized deferred financing fees and debt issuance costs of approximately $0.1 million were written off to loss on extinguishment of debt in the accompanying Consolidated Statement of Operations during the year ended December 31, 2020. On April 17, 2020, the Company entered into the $300.0 million Unsecured Term Loan G with Wells Fargo Bank, National Association, as administrative agent on behalf of the various lenders under the agreement. In connection with execution of the Unsecured Term Loan G, the Unsecured Term Loan B and Unsecured Term Loan C were paid in full. As of December 31, 2020, the Unsecured Term Loan G bore an interest rate of LIBOR plus a spread of 1.5% based on the Company’s debt rating, as defined in the loan agreement, and subject to a minimum rate for LIBOR of 0.25%. The Unsecured Term Loan G matures on April 16, 2021, subject to two one year extension options at the Company's discretion, and subject to certain conditions (other than lender discretion) such as the absence of default and the payment of an extension fee. At execution, the Company intended to exercise both extension options. To exercise the extension options the Company is required pay a fee equal to (i) 0.15% of the outstanding amount on the effective day of the first extension period and (ii) 0.20% of the outstanding amount on the effective day of the second extension period. In connection with the refinancing, the Company incurred approximately $2.1 million in deferred financing fees, including approximately $1.1 million of accrued extension fees, which are being amortized through the extended maturity date of April 18, 2023. In connection with the refinancing, the Company also recognized a loss on extinguishment of debt of approximately $0.7 million related to associated unamortized deferred financing fees and debt issuance costs related to the Unsecured Term Loan B and the Unsecured Term Loan C and other third-party costs. The Company is required to pay an annual fee of $35,000. The Unsecured Term Loan G has an accordion feature that allows the Company to increase its borrowing capacity to $600.0 million, subject to the satisfaction of certain conditions and lender consents. The Company and certain wholly owned subsidiaries of the Operating Partnership are guarantors of the Unsecured Term Loan G. The agreement also contains financial and other covenants substantially similar to the covenants in the Company's unsecured credit facility. On March 25, 2020, the Company drew the remaining $100.0 million of the $200.0 million Unsecured Term Loan F that was entered into on July 12, 2019. 2019 Debt Activity On July 25, 2019, the Company drew $175.0 million of the $175.0 million Unsecured Term Loan E that was entered into on July 26, 2018.

Unless otherwise terminated pursuant to the loan agreement, the Unsecured Term Loan F will mature on January 12, 2025. The Unsecured Term Loan F has a feature that allows the Company to request an increase in the aggregate size of the unsecured term loan of up to $400.0 million, subject to the satisfaction of certain conditions and lender consents. The agreement includes a delayed draw feature that allows the Company to draw up to six advances of at least $25.0 million each until July 12, 2020. To the extent that the Company did not request advances of the $200.0 million of aggregate commitments by July 12, 2020, the unadvanced commitments would terminate. The Unsecured Term Loan F has an unused commitment fee equal to 0.15% of its unused commitments, which began to accrue on October 10, 2019 and is due and payable monthly until the earlier of (i) the date that aggregate commitments of $200.0 million have been fully advanced, (ii) July 12, 2020, and (iii) the date that aggregate commitments have been reduced to zero pursuant to the terms of the agreement. The Company is required to pay an annual administrative agent fee of $35,000. The Company and certain wholly owned subsidiaries of the Operating Partnership are guarantors of the Unsecured Term Loan F. The agreement also contains financial and other covenants substantially similar to the covenants in the Company’s unsecured credit facility. On December 18, 2019, the Company drew $100.0 million of the $200.0 million Unsecured Term Loan F. Financial Covenant Considerations The Company’s ability to borrow under the unsecured credit facility, unsecured term loans, and unsecured notes are subject to its ongoing compliance with a number of customary financial covenants, including: • a maximum consolidated leverage ratio of not greater than 0.60:1.00; • a maximum secured leverage ratio of not greater than 0.40:1.00; • a maximum unencumbered leverage ratio of not greater than 0.60:1.00; • a minimum fixed charge ratio of not less than or equal to 1.50:1.00; and • a minimum unsecured interest coverage ratio of not less than or equal to 1.75:1.00.

The Company uses interest rate swaps to fix the rate of its long term variable rate debt. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. For derivatives designated and that qualify as cash flow hedges of interest rate risk, the gain or loss on the derivative is recorded in accumulated other comprehensive income and subsequently reclassified into interest expense in the same period during which the hedged transaction affects earnings. Amounts reported in accumulated other comprehensive income (loss) related to derivatives designated as qualifying cash flow hedges will be reclassified to interest expense as interest payments are made on the Company’s variable rate debt. The Company estimates that approximately $16.0 million will be reclassified from accumulated other comprehensive loss as an increase to interest expense over the next 12 months. The following table summarizes the effect of cash flow hedge accounting and the location in the consolidated financial statements for the years ended December 31, 2020, 2019 and 2018. Year ended December 31, Effect of Cash Flow Hedge Accounting (in thousands) 2020 2019 2018 Income (loss) recognized in accumulated other comprehensive loss on interest rate swaps $ (35,548) $ (21,248) $ 1,687 Income (loss) reclassified from accumulated other comprehensive loss into income as interest expense $ (13,439) $ 2,377 $ 1,377 Total interest expense presented in the Consolidated Statements of Operations in which the effects of cash flow hedges are recorded $ 62,343 $ 54,647 $ 48,817 Credit-risk-related Contingent Features The Company has agreements with each of its derivative counterparties that contain a provision where the Company could be declared in default on its derivative obligations if repayment of the underlying indebtedness is accelerated by the lender due to the Company’s default on the indebtedness. As of December 31, 2020, the Company had not breached the provisions of these agreements and has not posted any collateral related to these agreements. If the Company had breached any of its provisions at December 31, 2020, it could have been required to settle its obligations under the agreement of the interest rate swaps in a net liability position by counterparty plus accrued interest for approximately $41.6 million. Fair Value of Interest Rate Swaps The Company’s valuation of the interest rate swaps is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs including interest rate curves. The fair values of interest rate swaps are determined by using the market standard methodology of netting the discounted future fixed cash payments and the discounted expected variable cash receipts. The variable cash receipts are based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves. The Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Company has considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees. Although the Company has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by itself and its counterparties. However, as of December 31, 2020 and 2019, the Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuation of its derivatives. As a result, the Company has determined that its derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy. The following tables summarize the Company’s financial instruments that are accounted for at fair value on a recurring basis as of December 31, 2020 and 2019.

Restricted Stock-Based Compensation Pursuant to the 2011 Plan, the Company grants restricted shares of common stock to certain employees of the Company. The restricted shares of common stock are subject to time-based vesting. Restricted shares of common stock granted in 2020, 2019, and 2018, subject to the recipient’s continued employment, will vest over four years in equal installments on January 1 of each year beginning in 2021, 2020, and 2019, respectively. Refer to Note 8 for details on restricted shares of common stock granted on January 7, 2021. Holders of restricted shares of common stock have voting rights and rights to receive dividends. Restricted shares of common stock may not be sold, assigned, transferred, pledged or otherwise disposed of and are subject to a risk of forfeiture prior to the expiration of the applicable vesting period. The following table summarizes activity related to the Company’s unvested restricted shares of common stock for the years ended December 31, 2020, 2019 and 2018.

Noncontrolling Interest [Abstract]
Noncontrolling Interest	Noncontrolling Interest The following table summarizes the activity for noncontrolling interest in the Company for the years ended December 31, 2020, 2019 and 2018. Noncontrolling Interest LTIP Units Other Total Noncontrolling Interest Percentage Balance at December 31, 2017 1,457,070 2,639,617 4,096,687 4.1 % Granted/Issued 324,802 — 324,802 N/A Forfeited — — — N/A Conversions from LTIP units to Other Common Units (165,672) 165,672 — N/A Redemptions from Other Common Units to common stock — (352,055) (352,055) N/A Balance at December 31, 2018 1,616,200 2,453,234 4,069,434 3.5 % Granted/Issued 364,173 — 364,173 N/A Forfeited (16,618) — (16,618) N/A Conversions from LTIP units to Other Common Units (266,397) 266,397 — N/A Redemptions from Other Common Units to common stock — (680,137) (680,137) N/A Balance at December 31, 2019 1,697,358 2,039,494 3,736,852 2.5 % Granted/Issued 278,806 — 278,806 N/A Forfeited — — — N/A Conversions from LTIP units to Other Common Units (283,741) 283,741 — N/A Redemptions from Other Common Units to common stock — (730,420) (730,420) N/A Balance at December 31, 2020 1,692,423 1,592,815 3,285,238 2.0 % The weighted average grant date fair value of outstanding LTIP units was $21.64 per unit at January 1, 2020, $29.47 per unit for LTIP units granted during the year ended December 31, 2020, $18.27 per unit for LTIP units that were converted during the year ended December 31, 2020, and $23.49 per unit at December 31, 2020. The Company adjusts the carrying value of noncontrolling interest to reflect its share of the book value of the Operating Partnership when there has been a change in the Company’s ownership of the Operating Partnership. Such adjustments are recorded to additional paid-in capital as a rebalancing of noncontrolling interest on the accompanying Consolidated Statements of Equity. LTIP Units LTIP units are granted to certain executive officers and senior employees of the Company as part of their compensation, and to independent directors for their service. LTIP units are valued by reference to the value of the Company’s common stock and are subject to such conditions and restrictions as the compensation committee of the board of directors may determine, including continued employment or service. Vested LTIP units can be converted to Other Common Units on a one-for-one basis once a material equity transaction has occurred that results in the accretion of the member’s capital account to the economic equivalent of an Other Common Unit. All LTIP units, whether vested or not, will receive the same monthly per unit distributions as Other Common Units, which equal per share dividends on common stock. LTIP units granted in January 2020, 2019, and 2018 to certain senior executive officers and senior employees, subject to the recipient’s continued employment, will vest quarterly over four years, with the first vesting date having been March 31, 2020, 2019, and 2018, respectively. LTIP units granted in January 2020, 2019, and 2018 to independent directors, subject to the recipient’s continued service, will vest on January 1, 2021, 2020, and 2019, respectively. On March 12, 2018, the Company’s board of directors appointed Michelle Dilley to serve as director of the Company. On March 12, 2018, Ms. Dilley was granted 3,930 LTIP units which vested on January 1, 2019. Refer to Note 8 for a discussion of the LTIP units granted in January 2021, 2020, 2019, and 2018, pursuant to the January 2018, 2017, 2016 performance units, and the 2015 Outperformance Program (the “2015 OPP”), respectively. The fair value of the LTIP units at the date of grant was determined by a lattice-binomial option-pricing model based on a Monte Carlo simulation. The fair value of the LTIP units is based on Level 3 inputs and is a non-recurring fair value measurement. The following table summarizes the assumptions used in valuing such LTIP units granted during years ended December 31, 2020, 2019 and 2018 (excluding those LTIP units granted pursuant to the 2017 and 2016 performance units and those LTIP units granted pursuant to the 2015 OPP; refer to Note 8 for details).

The unrecognized compensation expense associated with the Company’s LTIP units at December 31, 2020 was approximately $4.6 million and is expected to be recognized over a weighted average period of approximately 2.3 years. The following table summarizes the aggregate fair value (at the vesting date) for the LTIP units that vested during years ended December 31, 2020, 2019 and 2018.

Subject to certain restrictions, investors who own Other Common Units have the right to cause the Operating Partnership to redeem any or all of their Other Common Units for cash equal to the then-current value of one share of the Company’s common stock, or, at the Company’s election, shares of common stock on a one-for-one basis. When redeeming the Other Common Unit for cash, the value of a share of common stock is calculated as the average common stock closing price on the NYSE for the 10 days immediately preceding the redemption notice date. Each Other Common Unit receives the same monthly distribution as a share of common stock.

Equity Incentive Plan

Equity Incentive Plan	12 Months Ended

Share-based Payment Arrangement [Abstract]
Equity Incentive Plan	Equity Incentive Plan The 2011 Plan provides for the issuance of equity-based awards, including stock options, stock appreciation rights, restricted stock, restricted stock units, unrestricted stock awards and other awards based on shares of the Company’s common stock, such as LTIP units in the Operating Partnership, that may be made by the Company directly to the executive officers, directors, employees, and other individuals providing bona fide services to or for the Company. Subject to certain adjustments identified within the 2011 Plan, the aggregate number of shares of the Company’s common stock that may be awarded under the 2011 Plan is 6,642,461 shares. Under the 2011 Plan, each LTIP unit awarded will be equivalent to an award of one share of common stock reserved under the 2011 Plan, thereby reducing the number of shares of common stock available for other equity awards on a one-for-one basis. The 2011 Plan may be terminated, amended, modified or suspended at any time by the board of directors, subject to stockholder approval as required by law or stock exchange rules. The 2011 Plan expires on March 31, 2021. Under the 2011 Plan, the Company grants performance units to certain key employees of the Company. The ultimate value of the performance units depends on the Company’s total stockholder return (“TSR”) over a three-year period (the “measuring period”). At the end of the measuring period, the performance units convert into shares of common stock, or, at the Company’s election and with the award recipient’s consent, LTIP units or other securities (“Award Shares”), at a rate depending on the Company’s TSR over the measuring period as compared to three different benchmarks and on the absolute amount of the Company’s TSR. A recipient of performance units may receive as few as zero shares or as many as 250% of the number of target units, plus deemed dividends. The target amount of the performance units is nominally allocated as: (i) 25% to the Company’s TSR compared to the TSR of an industry peer group; (ii) 25% to the Company’s TSR compared to the TSR of a size-based peer group; and (iii) 50% to the Company’s TSR compared to the TSR of the companies in the MSCI US REIT index. No dividends are paid to the recipient during the measuring period. At the end of the measuring period, if the Company’s TSR is such that the recipient earns Award Shares, the recipient will receive additional Award Shares relating to dividends deemed to have been paid and reinvested on the Award Shares. The Company, in the discretion of the compensation committee of the board of directors, may pay the cash value of the deemed dividends instead of issuing additional Award Shares. In January 2020, 2019, and 2018, the Company granted performance units approved by the compensation committee of the board of directors, under the 2011 Plan to certain key employees of the Company. The measuring periods commenced on January 1, 2020, 2019, and 2018, respectively, and end on December 31, 2022, 2021, and 2020, respectively. For the 2020 and 2019 performance units, the Award Shares are immediately vested at the end of the measuring period. For the 2018 performance units, one-half of the Award Shares and all dividend shares vest immediately. The other one-half of the Award Shares will be restricted (subject to forfeiture) and vest one year after the end of the measuring period. The fair value of the performance units at the date of grant was determined by a lattice-binomial option-pricing model based on a Monte Carlo simulation. The fair value of the performance units is based on Level 3 inputs and is a non-recurring fair value measurement. The performance unit equity compensation expense is recognized into earnings ratably from the grant date over the respective vesting periods. The following table summarizes the assumptions used in valuing the performance units granted during the years ended December 31, 2020, 2019 and 2018. Performance Units Assumptions Grant date January 8, 2020 January 7, 2019 January 5, 2018 Expected volatility 17.4 % 20.7 % 22.0 % Expected dividend yield 5.75 % 6.0 % 6.0 % Risk-free interest rate 1.59 % 2.56 % 2.09 % Fair value of performance units grant (in thousands) $ 5,389 $ 5,620 $ 5,456 On December 31, 2020, the measuring period pursuant to the 2018 performance units concluded and it was determined that the Company’s total stockholder return exceeded the threshold percentage and return hurdle. The compensation committee of the board of directors approved the issuance of 127,671 vested LTIP units and 44,591 vested shares of common stock to the participants (of which 17,731 shares of common stock were repurchased and retired), which were issued on January 7, 2021. The compensation committee of the board of directors also approved the issuance of 124,743 LTIP units and 6,352 restricted shares of common stock that will vest in one year on December 31, 2021, which were issued on January 7, 2021. On December 31, 2019, the measuring period pursuant to the 2017 performance units concluded and it was determined that the Company’s total stockholder return exceeded the threshold percentage and return hurdle. The compensation committee of the board of directors approved the issuance of 76,096 vested LTIP units and 46,376 vested shares of common stock to the participants (of which 18,241 shares of common stock were repurchased and retired), which were issued on January 8, 2020. The compensation committee of the board of directors also approved the issuance of 65,969 LTIP units and 3,398 restricted shares of common stock that vested in one year on December 31, 2020, which were issued on January 8, 2020. On December 31, 2018, the measuring period pursuant to the 2016 performance units concluded and it was determined that the Company’s total stockholder return exceeded the threshold percentage and return hurdle. The compensation committee of the board of directors approved the issuance of 102,216 vested LTIP units and 74,032 vested shares of common stock (of which 30,193 shares of common stock were repurchased and retired) to the participants, which were issued on January 7, 2019. The compensation committee of the board of directors also approved the issuance of 107,308 LTIP units and 22,678 restricted shares of common stock that vested in one year on December 31, 2019, which were issued on January 7, 2019. On January 1, 2018, the measuring period pursuant to the 2015 OPP concluded and it was determined that the Company’s total stockholder return exceeded the threshold percentage and return hurdle and a pool of approximately $6.2 million was awarded to the participants. The compensation committee of the board of directors approved the issuance of 183,256 vested LTIP units and 53,722 vested shares of common stock (of which 15,183 shares of common stock were repurchased and retired) to the participants, all of which were issued on January 5, 2018. The unrecognized compensation expense associated with the Company’s performance units at December 31, 2020 was approximately $5.9 million and is expected to be recognized over a weighted average period of approximately 1.6 years. At December 31, 2020 and 2019, the number of shares available for issuance under the 2011 Plan were 2,325,389 and 2,851,304, respectively. The number of shares available for issuance under the 2011 Plan as of December 31, 2020 do not include an allocation for the 2020 and 2019 performance units as the awards were not determinable as of December 31, 2020. The number of shares available for issuance under the 2011 Plan as December 31, 2019 do not include an allocation for the 2019 and 2018 performance units as the awards were not determinable as of December 31, 2019. Non-cash Compensation Expense The following table summarizes the amounts recorded in general and administrative expenses in the accompanying Consolidated Statements of Operations for the amortization of restricted shares of common stock, LTIP units, performance units, and the Company’s director compensation for the years ended December 31, 2020, 2019 and 2018.

Leases [Abstract]
Lessee, Operating Leases [Text Block]	Leases Lessor Leases The Company has operating leases in which it is the lessor for its rental property. Certain leases contain variable lease payments based upon changes in the Consumer Price Index (“CPI”). Certain leases contain options to renew or terminate the lease, and options for the lessee to purchase the rental property, all of which are predominately at the sole discretion of the lessee. The following table summarizes the components of rental income recognized during the years ended December 31, 2020 and 2019 included in the accompanying Consolidated Statements of Operations. Year ended December 31, Rental Income (in thousands) 2020 2019 Fixed lease payments $ 371,088 $ 313,426 Variable lease payments 103,389 84,927 Straight-line rental income 12,711 11,881 Net decrease to rental income related to above and below market lease amortization (4,363) (4,884) Total rental income $ 482,825 $ 405,350 During the years ended December 31, 2020 and 2019, the Company evaluated its operating leases and determined that the future collectability for certain leases was not reasonably assured. As a result the Company converted to the cash basis of accounting for these leases which resulted in a reduction of rental income of approximately $1.7 million and $0 for years ended December 31, 2020 and 2019, respectively, due to the reversal of accrued rent. Additionally, there was $2.2 million and $0 of contractual rental income that was not recognized for payments that were not received from the tenants for the years ended December 31, 2020 and 2019, respectively. As of December 31, 2020 and December 31, 2019, the Company had accrued rental income of approximately $60.0 million and $44.3 million, respectively, included in tenant accounts receivable on the accompanying Consolidated Balance Sheets. As of December 31, 2020 and December 31, 2019, the Company had approximately $30.1 million and $22.6 million, respectively, of total lease security deposits available in the form of existing letters of credit, which are not reflected on the accompanying Consolidated Balance Sheets. As of December 31, 2020 and December 31, 2019, the Company had approximately $0.7 million and $0.7 million, respectively, of lease security deposits available in cash, which are included in restricted cash on the accompanying Consolidated Balance Sheets. The Company’s remaining lease security deposits are commingled in cash and cash equivalents. These funds may be used to settle tenant accounts receivables in the event of a default under the related lease. As of December 31, 2020 and December 31, 2019, the Company’s total liability associated with these lease security deposits was approximately $11.0 million and $9.8 million, respectively, and is included in tenant prepaid rent and security deposits on the accompanying Consolidated Balance Sheets. The Company estimates that billings for real estate taxes, which are the responsibility of certain tenants under the terms of their leases and are not reflected on the Company’s consolidated financial statements, was approximately $21.1 million, $19.1 million and $15.0 million for the years ended December 31, 2020, 2019 and 2018, respectively. These amounts would have been the maximum real estate tax expense of the Company, excluding any penalties or interest, had the tenants not met their contractual obligations for these periods. The following table summarizes the maturity of fixed lease payments under the Company’s leases as of December 31, 2020. Year Maturity of Fixed Lease Payments (in thousands) 2021 $ 399,881 2022 $ 369,168 2023 $ 325,435 2024 $ 277,924 2025 $ 231,246 Thereafter $ 836,734 Lessee Leases The Company has operating leases in which it is the lessee for ground leases and its corporate office lease. These leases have remaining lease terms of approximately 5.5 years to 48.9 years. Certain ground leases contain options to extend the leases for ten years to 20 years, all of which are reasonably certain to be exercised, and are included in the computation of the Company’s right-of-use assets and operating lease liabilities.

Lessor, Operating Leases [Text Block]	Leases Lessor Leases The Company has operating leases in which it is the lessor for its rental property. Certain leases contain variable lease payments based upon changes in the Consumer Price Index (“CPI”). Certain leases contain options to renew or terminate the lease, and options for the lessee to purchase the rental property, all of which are predominately at the sole discretion of the lessee. The following table summarizes the components of rental income recognized during the years ended December 31, 2020 and 2019 included in the accompanying Consolidated Statements of Operations.

As a result the Company converted to the cash basis of accounting for these leases which resulted in a reduction of rental income of approximately $1.7 million and $0 for years ended December 31, 2020 and 2019, respectively, due to the reversal of accrued rent. Additionally, there was $2.2 million and $0 of contractual rental income that was not recognized for payments that were not received from the tenants for the years ended December 31, 2020 and 2019, respectively. As of December 31, 2020 and December 31, 2019, the Company had accrued rental income of approximately $60.0 million and $44.3 million, respectively, included in tenant accounts receivable on the accompanying Consolidated Balance Sheets. As of December 31, 2020 and December 31, 2019, the Company had approximately $30.1 million and $22.6 million, respectively, of total lease security deposits available in the form of existing letters of credit, which are not reflected on the accompanying Consolidated Balance Sheets. As of December 31, 2020 and December 31, 2019, the Company had approximately $0.7 million and $0.7 million, respectively, of lease security deposits available in cash, which are included in restricted cash on the accompanying Consolidated Balance Sheets. The Company’s remaining lease security deposits are commingled in cash and cash equivalents. These funds may be used to settle tenant accounts receivables in the event of a default under the related lease. As of December 31, 2020 and December 31, 2019, the Company’s total liability associated with these lease security deposits was approximately $11.0 million and $9.8 million, respectively, and is included in tenant prepaid rent and security deposits on the accompanying Consolidated Balance Sheets. The Company estimates that billings for real estate taxes, which are the responsibility of certain tenants under the terms of their leases and are not reflected on the Company’s consolidated financial statements, was approximately $21.1 million, $19.1 million and $15.0 million for the years ended December 31, 2020, 2019 and 2018, respectively. These amounts would have been the maximum real estate tax expense of the Company, excluding any penalties or interest, had the tenants not met their contractual obligations for these periods.

Earnings Per Share

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share The Company uses the two-class method of computing earnings per common share, which is an earnings allocation formula that determines earnings per share for common stock and any participating securities according to dividends declared (whether paid or unpaid) and participation rights in undistributed earnings. Basic net income per common share is computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted net income per common share is computed by dividing net income available to common stockholders by the sum of the weighted average number of common shares outstanding and any dilutive securities for the period. Restricted shares of common stock are considered participating securities as these stock-based awards contain non-forfeitable rights to dividends, unless and until a forfeiture occurs, and these awards must be included in the computation of earnings per share pursuant to the two-class method. During the years ended December 31, 2020, 2019 and 2018, there were 187,283, 217,623 and 195,281, respectively, unvested shares of restricted stock on a weighted average basis that were considered participating securities. Participating securities are included in the computation of diluted EPS using the treasury stock method if the impact is dilutive. Other potentially dilutive common shares from the Company’s performance units and forward sales agreements are considered when calculating diluted EPS. The following table reconciles the numerators and denominators in the computation of basic and diluted earnings per common share for the years ended December 31, 2020, 2019 and 2018.

Subsequent Events	Subsequent Events The Company identified the following events subsequent to December 31, 2020 that are not recognized in the financial statements. On January 7, 2021, the Company granted 83,952 restricted shares of common stock to certain employees of the Company pursuant to the 2011 Plan. The restricted shares of common stock granted will vest over four years in equal installments on January 1 of each year beginning January 1, 2022. The fair value of the restricted shares of common stock at the date of grant was $29.77 per share. On January 7, 2021, the Company granted 28,440 LTIP units to non-employee, independent directors, and 124,990 LTIP units to certain executive officers and senior employees pursuant to the 2011 Plan. The LTIP units granted to non-employee, independent directors will vest on January 1, 2022. The LTIP units granted to certain executive officers and senior employees will vest in equal quarterly installments over four years, with the first vesting date being March 31, 2021. The aggregate fair value of the LTIP units at the date of grant was approximately $4.3 million, as determined by a lattice-binomial option-pricing model based on a Monte Carlo simulation using an expected term of ten years, a weighted average volatility factor of 34.0%, a weighted average expected dividend yield of 5.0%, and a weighted average risk-free interest rate of 0.229%. The fair value of the LTIP units is based on Level 3 inputs and is a non-recurring fair value measurement. On January 7, 2021, the Company granted performance units to certain executive officers and senior employees pursuant to the 2011 Plan. The terms of the January 7, 2021 performance units are substantially the same as the performance units discussed in Note 8, except that the measuring period commences on January 1, 2021 and ends on December 31, 2023, and the Award Shares are immediately vested at the end of the measuring period. The aggregate fair value of the performance units at the date of grant was approximately $5.5 million, as determined by a lattice-binomial option-pricing model based on a Monte Carlo simulation using a weighted average volatility factor of 34.4%, a weighted average expected dividend yield of 5.0%, and a weighted average risk-free interest rate of 0.2271%. The fair value of the performance units is based on Level 3 inputs and is a non-recurring fair value measurement. On January 7, 2021, the Company adopted the STAG Industrial, Inc. Employee Retirement Vesting Program (the “Vesting Program”) to provide supplemental retirement benefits for eligible employees. The Company estimates that adoption of the Vesting Program will result in an increase of general and administrative expenses of approximately $2.3 million for the year ending December 31, 2021 due to the acceleration of non-cash compensation expense for certain eligible employees.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2020
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The Company’s consolidated financial statements include the accounts of the Company, the Operating Partnership and their subsidiaries. Interests in the Operating Partnership not owned by the Company are referred to as “Noncontrolling Common Units.” These Noncontrolling Common Units are held by other limited partners in the form of common units (“Other Common Units”) and long term incentive plan units (“LTIP units”) issued pursuant to the STAG Industrial, Inc. 2011 Equity Incentive Plan, as amended (the “2011 Plan”). All significant intercompany balances and transactions have been eliminated in the consolidation of entities. The financial statements of the Company are presented on a consolidated basis for all periods presented.
Adoption of New Accounting Pronouncements	New Accounting Standards New Accounting Standards Adopted In March 2020, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) 2020-04, Reference Rate Reform (Topic 848) . ASU 2020-04 contains practical expedients for reference rate reform related activities that impact debt, leases, derivatives and other contracts. The guidance in ASU 2020-04 is optional and may be elected over time as
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.
Rental Property	Rental Property and Deferred Leasing Intangibles Rental property is carried at cost less accumulated depreciation and amortization. Expenditures for maintenance and repairs are expensed as incurred. Significant renovations and betterments that extend the economic useful lives of assets are capitalized.
Rental Property Held for Sale	For properties classified as held for sale, the Company ceases depreciating and amortizing the rental property and values the rental property at the lower of depreciated and amortized cost or fair value less costs to dispose. The Company presents those properties classified as held for sale with any qualifying assets and liabilities associated with those properties as held for sale in the accompanying Consolidated Balance Sheets.
Business Combinations	Using information available at the time of acquisition, the Company allocates the purchase price of properties acquired based upon the fair value of the assets acquired and liabilities assumed, which generally consist of land, buildings, tenant improvements, mortgage debt assumed, and deferred leasing intangibles, which includes in-place leases, above market and below market leases, and tenant relationships. The process for determining the allocation to these components requires estimates and assumptions, including rental rates, discount rates and exit capitalization rates, and land value per square foot, as well as available market information. The fair value of the tangible assets of an acquired property considers the value of the property as if it were vacant. The portion of the purchase price that is allocated to above and below market leases is valued based on the present value of the difference between prevailing market rates and the in-place rates measured over a period equal to the remaining term of the lease term plus the term of any bargain renewal options. The purchase price is further allocated to in-place lease values and tenant relationships based on the Company’s evaluation of the specific characteristics of each tenant’s lease and its overall relationship with the respective tenant. The above and below market lease values are amortized into rental income over the remaining lease term. The value of in-place lease intangibles and tenant relationships are amortized over the remaining lease term (and expected renewal period of the respective lease for tenant relationships) as increases to depreciation and amortization expense. The remaining lease terms are adjusted for bargain renewal options or assumed exercises of early termination options, as applicable. If a tenant subsequently terminates its lease, any unamortized portion of above and below market leases is accelerated into rental income and the in-place lease value and tenant relationships are accelerated into depreciation and amortization expense over the shortened lease term. The purchase price allocated to deferred leasing intangible assets are included in rental property, net on the accompanying Consolidated Balance Sheets and the purchase price allocated to deferred leasing intangible liabilities are included in deferred leasing intangibles, net on the accompanying Consolidated Balance Sheets under the liabilities section.
Impairment or Disposal of Long-Lived Assets, Including Intangible Assets	The Company evaluates the carrying value of all tangible and intangible rental property assets and deferred leasing intangible liabilities (collectively, the “property”) held for use for possible impairment when an event or change in circumstance has occurred that indicates their carrying value may not be recoverable. The evaluation includes estimating and reviewing anticipated future undiscounted cash flows to be derived from the property. If such cash flows are less than the property’s carrying value, an impairment charge is recognized to the extent by which the property’s carrying value exceeds the estimated fair value. Estimating future cash flows is highly subjective and is based in part on assumptions regarding anticipated hold period, future occupancy, rental rates, capital requirements, and exit capitalization rates that could differ from actual results. The discount rate used to present value the cash flows for determining fair value is also subjective.
Depreciation and Amortization	Depreciation expense is computed using the straight-line method based on the following estimated useful lives. Description Estimated Useful Life Building 40 Years Building and land improvements (maximum) 20 Years Tenant improvements Shorter of useful life or terms of related lease
Lessee, Leases	LeasesFor leases in which the Company is the lessee, the Company recognizes a right-of-use asset and corresponding lease liability on the accompanying Consolidated Balance Sheets equal to the present value of the fixed lease payments. In determining the operating right-of-use asset and lease liability for the Company’s operating leases, the Company estimates an appropriate incremental borrowing rate on a fully-collateralized basis for the terms of the leases. The Company utilizes a market-based approach to estimate the incremental borrowing rate for each individual lease. Additionally, since the terms of our ground leases are significantly longer than the terms of borrowings available to the Company on a fully-collateralized basis, the estimate of this rate required significant judgment, and considered factors such as yields on outstanding public debt and other market based pricing on longer duration financing instruments.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents consist of cash and highly liquid short-term investments with original maturities of three months or less. The Company maintains cash and cash equivalents in United States banking institutions that may exceed amounts insured by the Federal Deposit Insurance Corporation. While the Company monitors the cash balances in its operating accounts, these cash balances could be impacted if the underlying financial institutions fail or are subject to other adverse conditions in the financial markets. To date, the Company has experienced no loss or lack of access to cash in its operating accounts, and mitigates this risk by using nationally recognized banking institutions.
Cash and Cash Equivalents, Restricted Cash and Cash Equivalents	Restricted Cash Restricted cash may include tenant security deposits, cash held in escrow for real estate taxes and capital improvements as required in various mortgage note agreements, and cash held by the Company’s transfer agent for preferred stock dividends that are distributed subsequent to period end. Restricted cash may also include cash held by qualified intermediaries to facilitate a like-kind exchange of real estate under Section 1031 of the Code. The following table presents a reconciliation of cash and cash equivalents and restricted cash reported on the accompanying Consolidated Balance Sheets to amounts reported on the accompanying Consolidated Statements of Cash Flows. Reconciliation of cash and cash equivalents and restricted cash (in thousands) December 31, 2020 December 31, 2019 Cash and cash equivalents $ 15,666 $ 9,041 Restricted cash 4,673 2,823 Total cash and cash equivalents and restricted cash $ 20,339 $ 11,864
Deferred Costs	Deferred Costs Deferred financing fees and debt issuance costs include costs incurred in obtaining debt that are capitalized and are presented as a direct deduction from the carrying amount of the associated debt liability that is not a line-of-credit arrangement on the accompanying Consolidated Balance Sheets. Deferred financing fees and debt issuance costs related to line-of-credit arrangements are presented as an asset in prepaid expenses and other assets on the accompanying Consolidated Balance Sheets. The deferred financing fees and debt issuance costs are amortized through interest expense over the life of the respective loans on a basis which approximates the effective interest method. Any unamortized amounts upon early repayment of debt are written off in the period of repayment as a loss on extinguishment of debt. Fully amortized deferred financing fees and debt issuance costs are written off upon maturity of the underlying debt. Leasing commissions include commissions and other direct and incremental costs incurred to obtain new tenant leases as well as to renew existing tenant leases, and are presented in prepaid expenses and other assets on the accompanying Consolidated Balance Sheets. Leasing commissions are capitalized and amortized over the terms of the related leases (and bargain renewal terms or assumed exercise of early termination options) using the straight-line method. If a lease terminates prior to the expiration of its initial term, any unamortized costs related to the lease are accelerated into amortization expense. Changes in leasing commissions are presented in the cash flows from operating activities section of the accompanying Consolidated Statements of Cash Flows.
Goodwill	Goodwill The excess of the cost of an acquired business over the net of the amounts assigned to assets acquired (including identified intangible assets) and liabilities assumed is recorded as goodwill. Goodwill of the Company of approximately $4.9 million represents amounts allocated to the assembled workforce from the acquired management company, and is presented in prepaid expenses and other assets on the accompanying Consolidated Balance Sheets. The Company’s goodwill has an indeterminate life and is not amortized, but is tested for impairment on an annual basis at December 31, or more frequently if events or changes in circumstances indicate that the asset might be impaired. The Company takes a qualitative approach to consider whether an impairment of goodwill exists prior to quantitatively determining the fair value of the reporting unit in step one of the impairment test. The Company has recorded no impairments to goodwill through December 31, 2020.
Use of Derivative Financial Instruments	Use of Derivative Financial Instruments The Company records all derivatives on the accompanying Consolidated Balance Sheets at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting, and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. The Company may enter into derivative contracts that are intended to
Fair Value of Financial Instruments	Fair Value of Financial Instruments Financial instruments include cash and cash equivalents, restricted cash, tenant accounts receivable, interest rate swaps, accounts payable, accrued expenses, unsecured credit facility, unsecured term loans, unsecured notes, and mortgage notes. See Note 4 for the fair value of the Company’s indebtedness. See Note 5 for the fair value of the Company’s interest rate swaps.
Commissions, Policy	Offering Costs Underwriting commissions and direct offering costs have been reflected as a reduction of additional paid-in capital on the accompanying Consolidated Balance Sheets and Consolidated Statements of Equity. Indirect costs associated with equity offerings are expensed as incurred and included in general and administrative expenses on the accompanying Consolidated Statements of Operations.
Dividends	DividendsEarnings and profits, which determine the taxability of dividends to stockholders, will differ from income reported for financial reporting purposes due to the differences for federal income tax purposes in the treatment of gains on the sale of real property, revenue and expense recognition, and in the estimated useful lives and basis used to compute depreciation. In addition, the Company’s distributions may include a return of capital. To the extent that the Company makes distributions in excess of its current and accumulated earnings and profits, such distributions would generally be considered a return of capital for federal income tax purposes to the extent of the holder’s adjusted tax basis in its shares. A return of capital may not be taxable. A return of capital has the effect of reducing the holder’s adjusted tax basis in its investment, which may or may not be taxable to the holder.
Revenue Recognition	Revenue Recognition All current leases are classified as operating leases and rental income is recognized on a straight-line basis over the term of the lease (and expected bargain renewal terms or assumed exercise of early termination options) when collectability is reasonably assured. Differences between rental income earned and amounts due under the lease are charged or credited, as applicable, to accrued rental income. The Company determined that for all leases where the Company is the lessor, that the timing and pattern of transfer of the non-lease components and associated lease components are the same, and that the lease components, if accounted for separately, would be classified as an operating lease. Accordingly, the Company has made an accounting policy election to recognize the combined component in accordance with Topic 842 as rental income on the accompanying Consolidated Statements of Operations. Rental income recognition commences when the tenant takes possession of or controls the physical use of the leased space and the leased space is substantially complete and ready for its intended use. In order to determine whether the leased space is substantially complete and ready for its intended use, the Company determines whether the Company or the tenant own the tenant improvements. When it is determined that the Company is the owner of the tenant improvements, rental income recognition begins when the tenant takes possession of or controls the physical use of the finished space, which is generally when the Company owned tenant improvements are completed. In instances when it is determined that the tenant is the owner of tenant improvements, rental income recognition begins when the tenant takes possession of or controls the physical use of the leased space. When the Company is the owner of tenant improvements or other capital items, the cost to construct the tenant improvements or other capital items, including costs paid for or reimbursed by the tenants, is recorded as capital assets. For these tenant improvements or other capital items, the amount funded by or reimbursed by the tenants are recorded as deferred revenue, which is amortized on a straight-line basis as income over the shorter of the useful life of the capital asset or the term of the related lease. Early lease termination fees are recorded in rental income on a straight-line basis from the notification date of such termination to the then remaining (not the original) lease term, if any, or upon collection if collection is not reasonably assured.
Gain on Sales of Rental Property	Gain on the Sales of Rental Property, netThe timing of the derecognition of a rental property and the corresponding recognition of gain on the sales of rental property, net is measured by various criteria related to the terms of the sale transaction, and if the Company has lost control of the property and the acquirer has gained control of the property after the transaction. If the derecognition criteria is met, the full gain is recognized.
Incentive and Equity-Based Employee Compensation Plans	Incentive and Equity-Based Employee Compensation Plans The Company grants equity-based compensation awards to its employees and directors in the form of restricted shares of common stock, LTIP units, and outperformance programs and performance units ( outperformance programs and performance units are collectively, “Performance-based Compensation Plans”) . See Notes 6, 7 and 8 for further discussion of restricted shares of common stock, LTIP units, and Performance-based Compensation Plans
Taxes	Taxes Federal Income Taxes The Company elected to be taxed as a REIT under the Code commencing with its taxable year ended December 31, 2011 and intends to continue to qualify as a REIT. As a REIT, the Company is generally not subject to corporate level federal income tax on the earnings distributed currently to its stockholders that it derives from its REIT qualifying activities. As a REIT, the Company is required to distribute at least 90% of its REIT taxable income to its stockholders and meet the various other requirements imposed by the Code relating to such matters as operating results, asset holdings, distribution levels and diversity of stock ownership. The Company will not be required to make distributions with respect to income derived from the activities conducted through subsidiaries that the Company elects to treat as taxable REIT subsidiaries (“TRS”) for federal income tax purposes, nor will it have to comply with income, assets, or ownership restrictions inside of the TRS. Certain activities that the Company undertakes must or should be conducted by a TRS, such as performing non-customary services for its tenants and holding assets that it cannot hold directly. A TRS is subject to federal and state income taxes. The Company’s TRS recognized a net income (loss) of approximately $0, $0.3 million and $(0.1) million, for the years ended December 31, 2020, 2019 and 2018, respectively, which has been included on the accompanying Consolidated Statements of Operations. State and Local Income, Excise, and Franchise Tax The Company and certain of its subsidiaries are subject to certain state and local income, excise and franchise taxes. Taxes in the amount of approximately $1.7 million, $1.2 million and $0.9 million have been recorded in other expenses on the accompanying Consolidated Statements of Operations for the years ended December 31, 2020, 2019 and 2018, respectively. Uncertain Tax Positions Tax benefits of uncertain tax positions are recognized only if it is more likely than not that the tax position will be sustained based solely on its technical merits, with the taxing authority having full knowledge of all relevant information. The measurement of a tax benefit for an uncertain tax position that meets the “more likely than not” threshold is based on a cumulative probability model under which the largest amount of tax benefit recognized is the amount with a greater than 50% likelihood of being realized upon ultimate settlement with the taxing authority having full knowledge of all the relevant information. As of December 31, 2020, 2019 and 2018, there were no liabilities for uncertain tax positions.
Earnings Per Share	Earnings Per ShareThe Company uses the two-class method of computing earnings per common share, which is an earnings allocation formula that determines earnings per share for common stock and any participating securities according to dividends declared (whether paid or unpaid) and participation rights in undistributed earnings. Basic net income per common share is computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted net income per common share is computed by dividing net income available to common stockholders by the sum of the weighted average number of common shares outstanding and any dilutive securities for the period.
Segment Reporting	Segment Reporting The Company manages its operations on an aggregated, single segment basis for purposes of assessing performance and making operating decisions and, accordingly, has only one reporting and operating segment.
Concentrations of Credit Risk	Concentrations of Credit Risk Concentrations of credit risk relevant to the Company may arise when a number of financing arrangements, including revolving credit facilities or derivatives, are entered into with the same lenders or counterparties, and have similar economic features that would cause their inability to meet contractual obligations. The Company mitigates the concentration of credit risk as it relates to financing arrangements by entering into loan syndications with multiple, reputable financial institutions and diversifying its debt counterparties. The Company also reduces exposure by diversifying its derivatives across multiple counterparties who meet established credit and capital guidelines.
