Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	ORGANIZATION Alexander’s, Inc. (NYSE: ALX) is a real estate investment trust (“REIT”), incorporated in Delaware, engaged in leasing, managing, developing and redeveloping its properties. All references to “we,” “us,” “our,” “Company” and “Alexander’s” refer to Alexander’s, Inc. and its consolidated subsidiaries. We are managed by, and our properties are leased and developed by, Vornado Realty Trust (“Vornado”) (NYSE: VNO). We have six properties in New York City consisting of: Operating properties • 731 Lexington Avenue, a 1,079,000 square foot multi-use building, comprising the entire block bounded by Lexington Avenue, East 59 th Street, Third Avenue and East 58 th Street in Manhattan. The building contains 939,000 and 140,000 of net rentable square feet of office and retail space, respectively. Bloomberg L.P. (“Bloomberg”) occupies all of the office space. The Home Depot (83,000 square feet) is the principal retail tenant; • Rego Park I, a 338,000 square foot shopping center, is located on Queens Boulevard and 63 rd Road in Queens. The center is anchored by a 112,000 square foot IKEA, a 50,000 square foot Burlington, a 46,000 square foot Bed Bath & Beyond and a 36,000 square foot Marshalls. On December 3, 2022, IKEA closed its store at the property. IKEA remains obligated under its lease which expires in December 2030. The lease includes a right to terminate effective no earlier than March 2026, subject to payment of rent through the termination date and an additional termination payment equal to the lesser of $10,000,000 or the amount of rent due under the remaining term; • Rego Park II, a 615,000 square foot shopping center, is located adjacent to the Rego Park I shopping center in Queens. The center is anchored by a 145,000 square foot Costco and a 133,000 square foot Kohl’s, which has been subleased; • The Alexander apartment tower, located above our Rego Park II shopping center, contains 312 units aggregating 255,000 square feet; and • Flushing, a 167,000 square foot building, located on Roosevelt Avenue and Main Street in Queens, that is sub-leased to New World Mall LLC. The property is ground leased through January 2027 with one 10-year extension option. Property to be developed • Rego Park III, a 140,000 square foot land parcel adjacent to the Rego Park II shopping center in Queens, at the intersection of Junction Boulevard and the Horace Harding Service Road. We have determined that our properties have similar economic characteristics and meet the criteria that permit the properties to be aggregated into one reportable segment (the leasing, management, development and redeveloping of properties in New York City). Our chief operating decision-maker assesses and measures segment operating results based on a performance measure referred to as net operating income at the individual operating segment. Net operating income for each property represents net rental revenues less operating expenses.

Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation – The accompanying consolidated financial statements include our accounts and those of our consolidated subsidiaries. All intercompany amounts have been eliminated. Our consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”), which requires us 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 consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - continued Recently Issued Accounting Literature - In March 2020, the Financial Accounting Standards Board (“FASB”) issued an update (“ASU 2020-04”) establishing Accounting Standards Codification (“ASC”) Topic 848 (“ASC 848”), Reference Rate Reform . 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. We have 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. In December 2022 the FASB issued accounting standard update 2022-06 that defers the sunset of ASC 848 from December 31, 2022 to December 31, 2024. We continue to evaluate the impact of the guidance and may apply other elections as applicable as additional changes in the market occur. In July 2021, the FASB issued an update ("ASU 2021-05") Lessors - Certain Leases with Variable Lease Payments to ASC Topic 842, Leases ("ASC 842"). ASU 2021-05 provides additional ASC 842 classification guidance as it relates to a lessor's accounting for certain leases with variable lease payments. ASU 2021-05 requires a lessor to classify a lease with variable payments that do not depend on an index or rate as an operating lease if either a sales-type lease or direct financing lease classification would trigger a day-one loss. ASU 2021-05 is effective for reporting periods beginning after December 15, 2021, with early adoption permitted. We adopted this update effective January 1, 2022 which did not have an impact on our consolidated financial statements. Real Estate – Real estate is carried at cost, net of accumulated depreciation and amortization. As of December 31, 2022 and 2021, the carrying amount of our real estate, net of accumulated depreciation and amortization, was $688,330,000 and $698,869,000, respectively. Maintenance and repairs are generally expensed as incurred. Depreciation requires an estimate by management of the useful life of each property and improvement as well as an allocation of the costs associated with a property to its various components. We capitalize all property operating expenses directly associated with and attributable to, the development and construction of a project, including interest expense. The capitalization period begins when development activities are underway and ends when it is determined that the asset is substantially complete and ready for its intended use, which is typically evidenced by the receipt of a temporary certificate of occupancy. General and administrative costs are expensed as incurred. Our properties, including properties to be developed in the future, are individually reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. An impairment exists when the carrying amount of an asset exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset, including an estimated terminal value calculated using an appropriate capitalization rate. Estimates of future cash flows are based on our current plans, intended holding periods and available market information at the time the analyses are prepared. For our development properties, estimates of future cash flows also include all future expenditures necessary to develop the asset, including interest payments that will be capitalized as part of the cost of the asset. An impairment loss is recognized only if the carrying amount of the asset is not recoverable and is measured based on the excess of the property’s carrying amount over its estimated fair value. If our estimates of future cash flows, anticipated holding periods, or fair values change, based on market conditions or otherwise, our evaluation of impairment charges may be different and such differences could be material to our consolidated financial statements. Estimates of future cash flows are subjective and are based, in part, on assumptions regarding future occupancy, rental rates and capital requirements that could differ materially from actual results. Plans to hold properties over longer periods decrease the likelihood of recording impairment losses. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - continued Revenue Recognition – Our rental revenues include revenues from the leasing of space to tenants at our properties and revenues from parking and tenant services. We have the following revenue recognition policies: • Lease revenues from the leasing of space to tenants at our properties. Revenues derived from base rent are recognized over the non-cancelable term of the related leases on a straight-line basis which includes the effects of rent steps and rent abatements. We commence rental revenue recognition when the underlying asset is available for use by the lessee. In addition, in circumstances where we provide a tenant improvement allowance for improvements that are owned by the tenant, we recognize the allowance as a reduction of rental revenue on a straight-line basis over the term of the lease. Revenues derived from the reimbursement of real estate taxes, insurance expenses and common area maintenance expenses are generally recognized in the same period as the related expenses are incurred. As lessor, we have elected to combine the lease components (base and variable rent), non-lease components (reimbursements of common area maintenance expenses) and reimbursement of real estate taxes and insurance expenses from our operating lease agreements and account for the components as a single lease component in accordance with ASC 842. • Parking revenue arising from the rental of parking spaces at our properties. This income is recognized as the services are transferred in accordance with ASC Topic 606, Revenue from Contracts with Customers (“ASC 606”). • Tenant services is revenue arising from sub-metered electric, elevator and other services provided to tenants at their request. This revenue is recognized as the services are transferred in accordance with ASC 606. Under ASC 842, we must assess on an individual lease basis whether it is probable that we will collect substantially all of the future lease payments. We consider the tenant’s payment history and current credit status when assessing collectability. When collectability is not deemed probable, we write-off the tenant’s receivables, including straight-line rent receivable, and limit lease income to cash received. We recognize changes in the collectability assessment of our operating leases as adjustments to rental revenues. Cash and Cash Equivalents – Cash and cash equivalents consist of highly liquid investments with original maturities of three months or less when purchased and are carried at cost, which approximates fair value, due to their short-term maturities. The majority of our cash and cash equivalents consist of (i) deposits at major commercial banks, which may at times exceed the Federal Deposit Insurance Corporation limit, (ii) money market funds, which invest in U.S. Treasury bills and (iii) certificates of deposit placed through an account registry service (“CDARS”). To date we have not experienced any losses on our invested cash. Restricted Cash – Restricted cash primarily consists of security deposits and other cash escrowed under loan and interest rate derivative agreements, including for debt service, real estate taxes, property insurance and capital improvements. Investments in U.S. Treasury Bills – Treasury bills are short-term debt obligations with maturities of one year or less backed by the U.S. Treasury Department. Treasury bills yield no interest, but are issued at a discount on their redemption prices. We classify our investments in U.S. Treasury bills as available-for-sale debt investments, recorded at fair value with any changes in fair value during the period recorded in other comprehensive income. These investments are considered Level 1 within the fair value hierarchy as they are highly liquid and are traded in an active secondary market. We use quoted market prices to determine the fair value of our investments in U.S. Treasury bills. Deferred Charges – Direct financing costs are deferred and amortized over the terms of the related agreements as a component of interest and debt expense. Direct and incremental costs related to successful leasing activities are capitalized and amortized on a straight-line basis over the lives of the related leases. All other deferred charges are amortized on a straight-line basis, which approximates the effective interest rate method, in accordance with the terms of the agreements to which they relate. Income Taxes – We operate in a manner intended to enable us to continue to qualify as a REIT under Sections 856 – 860 of the Internal Revenue Code of 1986, as amended (the “Code”). In order to maintain our qualification as a REIT under the Code, we must distribute at least 90% of our taxable income to stockholders each year. We distribute to our stockholders 100% of our taxable income and therefore, no provision for Federal income taxes is required. Dividends distributed for the year ended December 31, 2022 were characterized, for federal income tax purpos es, as 100.0% ordi nary income. Dividends distributed for the year ended December 31, 2021 were characterized, for federal income tax purposes, as 58.3% ordinary income and 41.7% of long-term capital gain income. Dividends distributed for the year ended December 31, 2020 were characterized, for federal income tax purposes, as 100.0% ordinary income. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - continued The estimated taxable income attributable to our common stockholders (unaudited) for the years ended December 31, 2022, 2021 and 2020 was approximately $64,960,000, $101,184,000, and $81,375,000, respectively. The book to tax differences between net income and estimated taxable income primarily result from differences in the income recognition or deductibility of depreciation and amortization, gains or losses from the sale of real estate and other capital transactions, straight-line rent adjustments, the change in fair value of marketable securities and income from discontinued operations. As of December 31, 2022, the net basis of our assets and liabilities for tax reporting purposes was approximately $137,734,000 lower than the amount reported for financial statement purposes.

Fair Value Disclosures [Abstract]
Fair Value Measurements	FAIR VALUE MEASUREMENTS ASC Topic 820, Fair Value Measurement (“ASC 820”) defines fair value and establishes a framework for measuring fair value. ASC 820 establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three levels: Level 1 – quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities as well as certain U.S. Treasury securities that are highly liquid and are actively traded in secondary markets; Level 2 – observable prices that are based on inputs not quoted in active markets, but corroborated by market data; and Level 3 – unobservable inputs that are used when little or no market data is available. The fair value hierarchy gives the highest priority to Level 1 inputs and the lowest priority to Level 3 inputs. In determining fair value, we utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible as well as consider counterparty credit risk in our assessment of fair value. 9. FAIR VALUE MEASUREMENTS - continued Financial Assets and Liabilities Measured at Fair Value Financial assets measured at fair value on our consolidated balance sheets as of December 31, 2022 consist of U.S. Treasury bills (classified as available for-sale) and interest rate derivatives which are presented in the table below based on their level in the fair value hierarchy.

As of December 31, 2022 our investments in U.S. Treasury bills have an aggregate accreted value of $267,809 prior to being marked to fair value and have remaining maturities of less than one year. Financial assets measured at fair value on our consolidated balance sheet as of December 31, 2021 consist of interest rate derivatives which are presented in the table below based on their level in the fair value hierarchy.

Cash equivalents are carried at cost, which approximates fair value due to their short-term maturities and are classified as Level 1. The fair value of our mortgages payable is calculated by discounting the future contractual cash flows of these instruments using current risk-adjusted rates available to borrowers with similar credit ratings, which are provided by a third-party specialist, and is classified as Level 2.

Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES Insurance We maintain general liability insurance with limits of $300,000,000 per occurrence and per property, of which the first $30,000,000 includes communicable disease coverage, and all-risk property and rental value insurance coverage with limits of $1.7 billion per occurrence, including coverage for acts of terrorism, with sub-limits for certain perils such as floods and earthquakes on each of our properties and excluding communicable disease coverage. Fifty Ninth Street Insurance Company, LLC (“FNSIC”), our wholly owned consolidated subsidiary, acts as a direct insurer for coverage for acts of terrorism, including nuclear, biological, chemical and radiological (“NBCR”) acts, as defined by the Terrorism Risk Insurance Act of 2002, as amended to date and which has been extended through December 2027. Coverage for acts of terrorism (including NBCR acts) is up to $1.7 billion per occurrence and in the aggregate. Coverage for acts of terrorism (excluding NBCR acts) is fully reinsured by third party insurance companies and the Federal government with no exposure to FNSIC. For NBCR acts, FNSIC is responsible for a $298,000 deductible and 20% of the balance of a covered loss, and the Federal government is responsible for the remaining 80% of a covered loss. We are ultimately responsible for any loss incurred by FNSIC. We continue to monitor the state of the insurance market and the scope and costs of coverage for acts of terrorism or other events. However, we cannot anticipate what coverage will be available on commercially reasonable terms in the future. We are responsible for uninsured losses and for deductibles and losses in excess of our insurance coverage, which could be material. The principal amounts of our mortgage loans are non-recourse to us and the loans contain customary covenants requiring us to maintain insurance. Although we believe that we have adequate insurance coverage for purposes of these agreements, we may not be able to obtain an equivalent amount of coverage at reasonable costs in the future. If lenders insist on greater coverage than we are able to obtain, it could adversely affect our ability to finance or refinance our properties.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2022
Accounting Policies [Abstract]
Basis of Presentation	The accompanying consolidated financial statements include our accounts and those of our consolidated subsidiaries.  All intercompany amounts have been eliminated. Our consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”), which requires us 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 consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods.  Actual results could differ from those estimates.
Recently Issued Accounting Literature	In March 2020, the Financial Accounting Standards Board (“FASB”) issued an update (“ASU 2020-04”) establishing Accounting Standards Codification (“ASC”) Topic 848 (“ASC 848”), Reference Rate Reform . 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. We have 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. In December 2022 the FASB issued accounting standard update 2022-06 that defers the sunset of ASC 848 from December 31, 2022 to December 31, 2024. We continue to evaluate the impact of the guidance and may apply other elections as applicable as additional changes in the market occur. In July 2021, the FASB issued an update ("ASU 2021-05") Lessors - Certain Leases with Variable Lease Payments to ASC Topic 842, Leases ("ASC 842"). ASU 2021-05 provides additional ASC 842 classification guidance as it relates to a lessor's accounting for certain leases with variable lease payments. ASU 2021-05 requires a lessor to classify a lease with variable payments that do not depend on an index or rate as an operating lease if either a sales-type lease or direct financing lease classification would trigger a day-one loss. ASU 2021-05 is effective for reporting periods beginning after December 15, 2021, with early adoption permitted. We adopted this update effective January 1, 2022 which did not have an impact on our consolidated financial statements.
Real Estate	Real estate is carried at cost, net of accumulated depreciation and amortization. As of December 31, 2022 and 2021, the carrying amount of our real estate, net of accumulated depreciation and amortization, was $688,330,000 and $698,869,000, respectively. Maintenance and repairs are generally expensed as incurred. Depreciation requires an estimate by management of the useful life of each property and improvement as well as an allocation of the costs associated with a property to its various components. We capitalize all property operating expenses directly associated with and attributable to, the development and construction of a project, including interest expense. The capitalization period begins when development activities are underway and ends when it is determined that the asset is substantially complete and ready for its intended use, which is typically evidenced by the receipt of a temporary certificate of occupancy. General and administrative costs are expensed as incurred. Our properties, including properties to be developed in the future, are individually reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. An impairment exists when the carrying amount of an asset exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset, including an estimated terminal value calculated using an appropriate capitalization rate. Estimates of future cash flows are based on our current plans, intended holding periods and available market information at the time the analyses are prepared. For our development properties, estimates of future cash flows also include all future expenditures necessary to develop the asset, including interest payments that will be capitalized as part of the cost of the asset. An impairment loss is recognized only if the carrying amount of the asset is not recoverable and is measured based on the excess of the property’s carrying amount over its estimated fair value. If our estimates of future cash flows, anticipated holding periods, or fair values change, based on market conditions or otherwise, our evaluation of impairment charges may be different and such differences could be material to our consolidated financial statements. Estimates of future cash flows are subjective and are based, in part, on assumptions regarding future occupancy, rental rates and capital requirements that could differ materially from actual results. Plans to hold properties over longer periods decrease the likelihood of recording impairment losses.
Revenue Recognition	Our rental revenues include revenues from the leasing of space to tenants at our properties and revenues from parking and tenant services. We have the following revenue recognition policies: • Lease revenues from the leasing of space to tenants at our properties. Revenues derived from base rent are recognized over the non-cancelable term of the related leases on a straight-line basis which includes the effects of rent steps and rent abatements. We commence rental revenue recognition when the underlying asset is available for use by the lessee. In addition, in circumstances where we provide a tenant improvement allowance for improvements that are owned by the tenant, we recognize the allowance as a reduction of rental revenue on a straight-line basis over the term of the lease. Revenues derived from the reimbursement of real estate taxes, insurance expenses and common area maintenance expenses are generally recognized in the same period as the related expenses are incurred. As lessor, we have elected to combine the lease components (base and variable rent), non-lease components (reimbursements of common area maintenance expenses) and reimbursement of real estate taxes and insurance expenses from our operating lease agreements and account for the components as a single lease component in accordance with ASC 842. • Parking revenue arising from the rental of parking spaces at our properties. This income is recognized as the services are transferred in accordance with ASC Topic 606, Revenue from Contracts with Customers (“ASC 606”). • Tenant services is revenue arising from sub-metered electric, elevator and other services provided to tenants at their request. This revenue is recognized as the services are transferred in accordance with ASC 606.
Cash and Cash Equivalents	Cash and cash equivalents consist of highly liquid investments with original maturities of three months or less when purchased and are carried at cost, which approximates fair value, due to their short-term maturities.  The majority of our cash and cash equivalents consist of (i) deposits at major commercial banks, which may at times exceed the Federal Deposit Insurance Corporation limit, (ii) money market funds, which invest in U.S. Treasury bills and (iii) certificates of deposit placed through an account registry service (“CDARS”). To date we have not experienced any losses on our invested cash.
Restricted Cash	Restricted cash primarily consists of security deposits and other cash escrowed under loan and interest rate derivative agreements, including for debt service, real estate taxes, property insurance and capital improvements.
Investments in U.S Treasury Bills	Treasury bills are short-term debt obligations with maturities of one year or less backed by the U.S. Treasury Department. Treasury bills yield no interest, but are issued at a discount on their redemption prices. We classify our investments in U.S. Treasury bills as available-for-sale debt investments, recorded at fair value with any changes in fair value during the period recorded in other comprehensive income. These investments are considered Level 1 within the fair value hierarchy as they are highly liquid and are traded in an active secondary market. We use quoted market prices to determine the fair value of our investments in U.S. Treasury bills.
Deferred Charges	Direct financing costs are deferred and amortized over the terms of the related agreements as a component of interest and debt expense.  Direct and incremental costs related to successful leasing activities are capitalized and amortized on a straight-line basis over the lives of the related leases.  All other deferred charges are amortized on a straight-line basis, which approximates the effective interest rate method, in accordance with the terms of the agreements to which they relate.
Income Taxes	We operate in a manner intended to enable us to continue to qualify as a REIT under Sections 856 – 860 of the Internal Revenue Code of 1986, as amended (the “Code”).  In order to maintain our qualification as a REIT under the Code, we must distribute at least 90% of our taxable income to stockholders each year. We distribute to our stockholders 100% of our taxable income and therefore, no provision for Federal income taxes is required. Dividends distributed for the year ended December 31, 2022 were characterized, for federal income tax purposes, as 100.0% ordinary income. Dividends distributed for the year ended December 31, 2021 were characterized, for federal income tax purposes, as 58.3% ordinary income and 41.7% of long-term capital gain income. Dividends distributed for the year ended December 31, 2020 were characterized, for federal income tax purposes, as 100.0% ordinary income.
Fair Value Measurements	ASC Topic 820, Fair Value Measurement (“ASC 820”) defines fair value and establishes a framework for measuring fair value.
Property, Plant and Equipment	As the results related to Kings Plaza were previously classified as discontinued operations, we have classified the gain as “income from discontinued operations” on our consolidated statement of income for the year ended December 31, 2021 in accordance with the provisions of ASC Topic 360, Property, Plant and Equipment .
Stock-based Compensation	We account for stock-based compensation in accordance with ASC Topic 718, Compensation – Stock Compensation (“ASC 718”). Our 2016 Omnibus Stock Plan (the “Plan”) provides for grants of incentive and non-qualified stock options, restricted stock, stock appreciation rights, deferred stock units (“DSUs”) and performance shares, as defined, to the directors, officers and employees of the Company and Vornado.
