Summary Of Significant Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Basis of Presentation Due to the Company’s ability as general partner to control either through ownership or by contract the Operating Partnership and its subsidiaries, the Operating Partnership and each such subsidiary has been consolidated with the Company for financial reporting purposes, except for any unconsolidated properties/entities. Real Estate Assets and Depreciation of Investment in Real Estate The Company expects that substantially all of its acquisitions will be accounted for as asset acquisitions. In an asset acquisition, the Company is required to capitalize transaction costs and allocate the purchase price on a relative fair value basis (including any identified intangible assets). For the years ended December 31, 2022 and 2021, all acquisitions were considered asset acquisitions. In making estimates of relative fair values for purposes of allocating purchase price, the Company utilizes a number of sources, including independent appraisals that may be obtained in connection with the acquisition or financing of the respective property, our own analysis of recently acquired or developed and existing comparable properties in our portfolio and other market data. The Company also considers information obtained about each property as a result of its pre-acquisition due diligence, marketing and leasing activities in estimating the relative fair value of the tangible and intangible assets/liabilities acquired. The Company allocates the purchase price of acquired real estate to various components as follows: • Land – Based on actual purchase price adjusted to an allocation of the relative fair value (as necessary) if acquired separately or market research/comparables if acquired with an operating property. • Furniture, Fixtures and Equipment – Based on an estimate of the allocation of the relative fair value of the appliances and fixtures inside an apartment unit. The per-apartment unit amount applied depends on the economic age of the apartment units acquired. Depreciation is calculated on the straight-line method over an estimated useful life of five to ten years . • Lease Intangibles – The Company considers the value of acquired in-place leases and above/below market leases and the amortization period is the average remaining term of each respective acquired lease. • Other Intangible Assets – The Company considers whether it has acquired other intangible assets, including any customer relationship intangibles and the amortization period is the estimated useful life of the acquired intangible asset. • Building – Based on the allocation of the relative fair value determined on an “as-if vacant” basis. Depreciation is calculated on the straight-line method over an estimated useful life of thirty years . • Long-Term Debt – The Company calculates the allocation of the relative fair value by discounting the remaining contractual cash flows on each instrument at the current market rate for those borrowings. Replacements inside an apartment unit such as appliances and carpeting are depreciated over an estimated useful life of five to ten years . Expenditures for ordinary maintenance and repairs are expensed to operations as incurred and significant renovations and building improvements that improve and/or extend the useful life of the asset are capitalized over their estimated useful life, generally five to fifteen years . Initial direct leasing costs are expensed as incurred as such expense approximates the deferral and amortization of initial direct leasing costs over the lease terms. The Company classifies real estate assets as real estate held for sale when it is probable a property will be disposed of. The Company classifies properties under development and/or expansion and properties in the lease-up phase (including land) as construction-in-progress until construction has been completed and certificates of occupancy permits have been obtained. Impairment of Long-Lived Assets At least quarterly, the Company evaluates its long-lived assets, including its investment in real estate, for indicators of impairment. The judgments regarding the existence of impairment indicators are based on factors such as operational performance, market conditions, legal, regulatory and environmental concerns, the Company’s intent and ability to hold the related asset, as well as any significant cost overruns on development properties. Future events could occur which would cause the Company to conclude that impairment indicators exist and an impairment loss is warranted. If an impairment indicator exists, the Company performs the following: • For long-lived operating assets to be held and used, the Company compares the expected future undiscounted cash flows for the long-lived asset against the carrying amount of that asset. If the sum of the estimated undiscounted cash flows is less than the carrying amount of the asset, the Company would make an estimate of the fair value for the particular asset and would record an impairment loss for the difference between the estimated fair value and the carrying amount of the asset. In determining the future undiscounted cash flows or the estimated fair value of an asset there is judgment in estimating the expected future rental revenues, operating expenses and discount and capitalization rates. • For long-lived non-operating assets (projects under development and land held for development), management evaluates major cost overruns, market conditions that could affect lease-up projections, intent and ability to hold the asset, and any other indicators of impairment. If any of the indicators were to suggest impairment was present, a recoverability analysis would be performed and the carrying value of the asset would be adjusted accordingly to fair value. • For long-lived assets to be disposed of, an impairment loss is recognized when the estimated fair value of the asset, less the estimated cost to sell, is less than the carrying amount of the asset measured at the time that the Company has determined it will sell the asset. Long-lived assets held for sale and the related liabilities are separately reported, with the long-lived assets reported at the lower of their carrying amounts or their estimated fair values, less their costs to sell, and are not depreciated after reclassification to real estate held for sale. See Note 4 for further discussion of the Company’s impairment charge on a land parcel in 2021. Impairment of Investments in Unconsolidated Entities and Other Investments At least quarterly, the Company evaluates its investments in unconsolidated entities and other investments for indicators of other than temporary impairment, considering whether there has been a change to events or circumstances that would impact recoverability of the Company’s investment as well as any changes with regards to the Company's intent and ability to hold the investment to recover its carrying value. Cost Capitalization See the Real Estate Assets and Depreciation of Investment in Real Estate section for a discussion of the Company’s policy with respect to capitalization vs. expensing of fixed asset/repair and maintenance costs. For all development, capital and renovation projects, the Company uses its professional judgment in determining whether such costs meet the criteria for capitalization or must be expensed as incurred. The Company capitalizes interest, real estate taxes and insurance, as well as payroll for those individuals directly responsible for and who spend their time on the execution and supervision of development activities. Additionally, the Company capitalizes payroll for those individuals directly responsible for and who spend their time on the execution and supervision of major capital and/or renovation projects. Capitalization ends when the asset, or a portion of the asset, is substantially completed and ready for its intended use. These costs are reflected on the balance sheets as increases to depreciable property and/or construction-in-progress. During the years ended December 31, 2022 and 2021, the Company capitalized $ 15.6 mil lion and $ 13.9 million, respectively, of payroll and associated costs of employees directly responsible for and who spend their time on the execution and supervision of development activities as well as major capital and/or renovation projects. Cash and Cash Equivalents The Company considers all demand deposits, money market accounts and investments in certificates of deposit with a maturity of three months or less at the date of purchase to be cash equivalents. The Company maintains its cash and cash equivalents at financial institutions. The combined account balances at one or more institutions typically exceed the Federal Deposit Insurance Corporation (“FDIC”) insurance coverage, and, as a result, there is a concentration of credit risk related to amounts on deposit in excess of FDIC insurance coverage. The Company believes that the risk is not significant, as the Company does not anticipate the financial institutions’ non-performance. Fair Value of Financial Instruments The valuation of financial instruments requires the Company to make estimates and judgments that affect the fair value of the instruments. The Company, where possible, bases the fair values of its financial instruments on listed market prices and third-party quotes. Where these are not available, the Company bases its estimates on current instruments with similar terms and maturities or on other factors relevant to the financial instruments. In the normal course of business, the Company is exposed to the effect of interest rate changes. The Company may seek to manage these risks by following established risk management policies and procedures, including the use of derivatives to hedge interest rate risk on debt instruments. The Company may also use derivatives to manage commodity prices in the daily operations of the business. The Company has a policy of only entering into derivative contracts with major financial institutions based upon their credit ratings and other factors. When viewed in conjunction with the underlying and offsetting exposure that the derivatives are designed to hedge, the Company has not sustained a material loss from these instruments nor does it anticipate any material adverse effect on its net income or financial position in the future. The Company recognizes all derivatives as either assets or liabilities in the consolidated balance sheets and measures those instruments at fair value. In addition, fair value adjustments will affect either shareholders’ equity/partners’ capital or net income depending on whether the derivative instruments qualify as a hedge for accounting purposes and, if so, the nature of the hedging activity. When the terms of an underlying transaction are modified, or when the underlying transaction is terminated or completed, all changes in the fair value of the instrument are marked-to-market with changes in value included in net income each period until the instrument matures. Any derivative instrument used for risk management that does not meet the hedging criteria is marked-to-market each period. The Company does not use derivatives for trading or speculative purposes. See Note 10 for additional derivatives discussion. Leases and Revenue Recognition Rental income attributable to residential leases is recorded on a straight-line basis over the term of the lease when reasonably assured they are collectible, which is not materially different than if it were recorded when due from residents and recognized monthly as it was earned. Residential apartment leases may include lease income related to such items as utility recoveries, parking rent, storage rent and pet rent that the Company treats as a single lease component because the amenities cannot be leased on their own and the timing and pattern of revenue recognition are the same. Leases entered into between a resident and a property for the rental of an apartment unit are generally year-to-year, renewable upon consent of both parties on an annual or monthly basis. Rental income attributable to non-residential leases is also recorded on a straight-line basis over the term of the lease when reasonably assured they are collectible. Non-residential leases may include lease income related to such items as utility recoveries, parking rent and storage rent that the Company treats as a single lease component because the amenities cannot be leased on their own and the timing and pattern of revenue recognition are the same. Non-residential leases generally have five to ten year lease terms with market-based renewal options and consist of ground floor retail spaces and master-leased parking garages that serve as additional amenities for our residents. The majority of the Company’s revenue is derived from residential, non-residential and other lease income. Our revenue streams have the same timing and pattern of revenue recognition across our reportable segments, with consistent allocations between the lease and revenue recognition standards. The Company elected an accounting policy to account for both its lease and non-lease components (specifically common area maintenance charges) as a single lease component under the lease standard. The Company is a lessor for its residential and non-residential leases and is a lessee for its corporate headquarters and regional offices and ground leases for land underlying current operating properties or projects under development. If applicable, lease agreements must be evaluated to determine the accounting treatment as a finance or operating lease in accordance with the lease standard. The lease standard also requires lessees to recognize on the balance sheet: (a) a liability for the lease obligation (initially measured at the present value of the future lease payments not yet paid over the lease term); and (b) an asset for its right to use the underlying asset (initially equal to the lease liability). The Company uses estimates and judgments on the discount rate used to calculate the present value of the future lease payments. The Company uses its incremental borrowing rate as the discount rate because the Company typically cannot readily determine the rate implicit in the lease. Since the Company’s credit backs the corporate office lease obligations and the lease terms are generally ten years or less, the discount rate range was estimated by using the Company’s borrowing rates for actual pricing data. The discount rate range for ground leases takes into account various factors, including the longer life of the ground leases, and was estimated by using the Company’s borrowing rates for actual pricing data through 30 years and other long-term market rates. The Company’s revenue streams that are not accounted for under the lease standard include: • Parking revenue – The Company’s parking revenue, not related to leasing, is derived primarily from monthly and transient daily parking and is accounted for at the point in time when control of the goods or services transfers to the customer and our performance obligation is satisfied. • Other rental and non-rental related revenue – The Company receives other income, including, but not limited to: (a) ancillary income, such as laundry, renters insurance and cable income; (b) net settlement income; and (c) miscellaneous fee income. • Fee and asset management revenue and interest income – The Company’s fee and asset management revenue and interest income are recorded on an accrual basis. • Gains or losses on sales of real estate properties – The Company accounts for the sale of real estate properties and any related gain recognition in accordance with the accounting guidance applicable to sales of real estate, which establishes standards for recognition of profit on all real estate sales transactions. The Company recognizes the sale and associated gain or loss from the disposition when control transfers to unrelated third parties, contingencies have been removed and sufficient cash consideration has been received by the Company. See Note 8 for the Company’s rental income detail allocated between the lease and revenue recognition standards. The Company’s allowance for doubtful accounts (which offsets accounts receivable and is included within other assets on the consolidated balance sheets) and bad debts (which reduce rental income on the consolidated statements of operations and comprehensive income) have historically been very modest, particularly in our residential business, given the quality of our resident base and asset class. However, due to the impact of the novel coronavirus (“COVID-19”) pandemic and extended eviction moratoriums enacted during the pandemic, the allowance for doubtful accounts and bad debts became elevated during 2020 and remained elevated in 2021 and 2022. In accordance with the lease standard, if we determine the lease payments are not probable of collection (based on known troubled accounts, rent deferral plans granted, historical experience and other currently available evidence), we fully reserve for any unpaid amounts, deferred rent receivable, variable lease payments and straight-line receivable balances and recognize rental income only if cash is received. If the Company’s estimates of collectibility differ from the cash received, then the timing and amount of the Company’s reported revenue could be impacted. See Note 8 for additional details. Share-Based Compensation The Company expenses share-based compensation for employee and trustee grants of restricted shares, restricted units and share options. Any common share of beneficial interest, $ 0.01 par value per share (the “Common Shares”), issued pursuant to EQR’s incentive equity compensation and employee share purchase plans will result in ERPOP issuing units of partnership interest (“OP Units”) to EQR on a one-for-one basis, with ERPOP receiving the net cash proceeds of such issuances. See Note 12 for further discussion. Income and Other Taxes EQR has elected to be taxed as a REIT. This, along with the nature of the operations of its operating properties, resulted in no provision for federal income taxes at the EQR level. In addition, ERPOP generally is not liable for federal income taxes as the partners should recognize their allocable share of income or loss in their tax returns; therefore no provision for federal income taxes has been made at the ERPOP level. Historically, the Company has generally only incurred certain state and local income, excise and franchise taxes. The Company has elected taxable REIT subsidiary status for certain of its corporate subsidiaries and, as a result, these entities will incur both federal and state income taxes on any taxable income of such entities after consideration of any net operating losses. The Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) included tax provisions which increased allowable interest expense deductions for 2020 (no increases for 2021 and 2022) and increased the ability for taxpayers to use net operating losses. These provisions did not result in a material impact to the Company’s taxable income or tax liabilities. The CARES Act also allowed corporations to request accelerated refunds of their alternative minimum tax (“AMT”) credit. Prior to enactment of this provision, the remaining credits would have been refunded in installments in 2020, 2021 and 2022. We received a refund of our remaining $ 1.6 million in AMT credits during the year ended December 31, 2020. The Company’s provision for income and other tax expense (benefit) was as follows for the years ended December 31, 2022, 2021 and 2020 (amounts in thousands): Year Ended December 31, 2022 2021 2020 State and local income, franchise and excise tax (benefit) $ 900 $ 915 $ 852 Income and other tax expense (benefit) (1) $ 900 $ 915 $ 852 (1) All provisions for income tax amounts are current and none are deferred. During the years ended December 31, 2022, 2021 and 2020, the tax character of the Company’s dividends and distributions were as follows: Year Ended December 31, 2022 (1) 2021 (2) 2020 (3) Tax character of dividends and distributions: Ordinary dividends $ 1.75466 $ 1.40791 $ 1.34739 Long-term capital gain 0.42850 0.73687 0.77923 Unrecaptured section 1250 gain 0.29434 0.26522 0.24838 Dividends and distributions per Common Share/Unit outstanding $ 2.47750 $ 2.41000 $ 2.37500 (1) The Company’s fourth quarter 2022 dividends and distributions of $ 0.625 per Common Share/Unit outstanding will be included as taxable income in calendar year 2023. (2) The Company’s fourth quarter 2021 dividends and distributions of $ 0.6025 per Common Share/Unit outstanding was included as taxable income in calendar year 2022. (3) The Company’s fourth quarter 2020 dividends and distributions of $ 0.6025 per Common Share/Unit outstanding was included as taxable income in calendar year 2021. The Company issued Internal Revenue Service (“IRS”) Form 1099-DIV to shareholders to report the tax character of Company distributions consistent with these amounts. The Company provides additional information to assist shareholders in the preparation of their tax returns. For 2022, the Company reported an AMT preference adjustment equal to $( 0.01 ) per share a nd disclosed amounts defined under Treasury Regulation §1.1061-6(c) as “One Year Amounts Disclosure” and “Three Year Amounts Disclosure” equal to $ 0.00979 per share and $ 0.00000 per share, resp ectively. Principles of Consolidation The Company may hold an interest in subsidiaries, partnerships, joint ventures and other similar entities and accounts for these interests in accordance with the consolidation guidance. The Company first determines whether to consolidate the entity as a variable interest entity (“VIE”) or voting interest entity, or to account for the interest under the equity method of accounting as an unconsolidated entity. In situations in which we have concluded that an entity qualifies as a VIE, it is generally because the equity investors of VIEs do not have sufficient equity at risk to finance their activities without additional subordinated financial support or do not have substantive voting rights. The Company consolidates an entity when it is considered to be the primary beneficiary of the VIE or when it controls the entity through ownership of a majority voting interest. A primary beneficiary has the power to direct the activities that most significantly impact the VIE’s performance and has the obligation to absorb the expected losses or the right to receive the expected residual returns that could potentially be significant to the VIE. In evaluating whether the entity is a VIE and/or the Company is the primary beneficiary of the entity, the Company considers several factors, including, but not limited to, proportionate share or ownership of the VIE, funding and financing sources, the business purpose of the entity, related parties, developer and property management fees and agreement terms regarding major decisions, participating and voting rights, contributions and distributions. Investments in Unconsolidated Entities The Company accounts for investments in unconsolidated entities under the equity method of accounting and measures the investments initially at cost. The Company subsequently adjusts the carrying amount by additional cash and non-cash contributions and distributions and its proportionate share of the earnings and losses of such entities. The proportionate share of the earnings and losses are also recognized in the consolidated statements of operations and comprehensive income. In addition, we may earn fees for providing property management services or construction oversight. Noncontrolling Interests A noncontrolling interest in a subsidiary (minority interest) is an ownership interest in the consolidated entity that should be reported as equity in the consolidated financial statements and separate from the parent company’s equity. In addition, consolidated net income is required to be reported at amounts that include the amounts attributable to both the parent and the noncontrolling interest and the amount of consolidated net income attributable to the parent and the noncontrolling interest are required to be disclosed on the face of the consolidated statements of operations and comprehensive income. See Note 3 for further discussion. Operating Partnership: Net income is allocated to noncontrolling interests based on their respective ownership percentage of the Operating Partnership. The ownership percentage is calculated by dividing the number of OP Units held by the noncontrolling interests by the total OP Units held by the noncontrolling interests and EQR. Issuance of additional Common Shares and OP Units changes the ownership interests of both the noncontrolling interests and EQR. Such transactions and the related proceeds are treated as capital transactions. Partially Owned Properties: The Company reflects noncontrolling interests in partially owned properties on the balance sheet for the portion of properties consolidated by the Company that are not wholly owned by the Company. The earnings or losses from those properties attributable to the noncontrolling interests are generally based on ownership percentage and are reflected as noncontrolling interests in partially owned properties in the consolidated statements of operations and comprehensive income. Partners’ Capital The “Limited Partners” of ERPOP include various individuals and entities that contributed their properties to ERPOP in exchange for OP Units. The “General Partner” of ERPOP is EQR. Net income is allocated to the Limited Partners based on their respective ownership percentage of ERPOP. The ownership percentage is calculated by dividing the number of OP Units held by the Limited Partners by the total OP Units held by the Limited Partners and the General Partner. Issuance of additional Common Shares and OP Units changes the ownership interests of both the Limited Partners and EQR. Such transactions and the related proceeds are treated as capital transactions. Redeemable Noncontrolling Interests – Operating Partnership / Redeemable Limited Partners The Company classifies Redeemable Noncontrolling Interests – Operating Partnership / Redeemable Limited Partners in the mezzanine section of the consolidated balance sheets for the portion of OP Units that EQR is required, either by contract or securities law, to deliver registered Common Shares to the exchanging OP Unit holder. The redeemable noncontrolling interest units / redeemable limited partner units are adjusted to the greater of carrying value or fair market value based on the Common Share price of EQR at the end of each respective reporting period. See Note 3 for further discussion. Use of Estimates In preparation of the Company’s financial statements in conformity with accounting principles generally accepted in the United States, management makes 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 as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. Recent Accounting Pronouncements In August 2020, the Financial Accounting Standards Board (“FASB”) issued an amendment to the debt and equity financial instruments standards which simplifies the accounting for convertible instruments and accounting for contracts in an entity’s own equity. The Company adopted the standard when effective on January 1, 2022 and it had no impact on its consolidated results of operations and financial position. In March 2020, the FASB issued an amendment to the reference rate reform standard which provides the option for a limited period of time to ease the potential burden in accounting for, or recognizing the effects of, reference rate reform on contract modifications and hedge accounting. The new standard was effective for the Company upon issuance and elections could be made through December 31, 2024. The Company elected to apply the hedge accounting expedients and 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. In April 2020, a FASB staff question and answer document was issued which intended to reduce the challenges of evaluating the enforceable rights and obligations of leases for concessions granted to lessees in response to the COVID-19 pandemic. We elected not to evaluate whether qualifying concessions provided by the Company in response to the COVID-19 pandemic are a lease modification, subject to the criteria that the total payments under the amended lease cannot result in a substantial increase in the rights of the lessor or obligations of the lessee. We also elected to treat the concessions as though they were contemplated as part of the existing contracts and therefore will not apply lease modification rules to the qualifying lease concession amendments. As such, deferrals deemed collectible are recorded as rental receivables with no change to timing of rental revenues and deferrals deemed non-collectible and abatements reduce rental revenues in the deferral/abatement period and cause rental revenues to effectively follow a cash basis related to the changes. The accounting elections provided by the FASB mainly apply to the Company’s non-residential leases and the majority of the amendments will not require a straight-line adjustment. See Note 8 for additional discussion. In June 2016, the FASB issued a standard which requires companies to adopt a new approach for estimating credit losses on certain types of financial instruments, such as trade and other receivables and loans. The standard requires entities to estimate a lifetime expected credit loss for most financial instruments, including trade receivables. In November 2018, the FASB issued an amendment excluding operating lease receivables accounted for under the lease standard from the scope of the credit losses standard. The Company adopted this standard as required effective January 1, 2020, and it did not have a material effect on its consolidated results of operations and financial position. Other The Company is the controlling partner in various consolidated partnerships ow ning 15 properties consisting of 3,114 ap artment units having a noncontrolling interest deficit balance of $ 0.7 million at December 31, 2022 . The Company is required to make certain disclosures regarding noncontrolling interests in consolidated limited-life subsidiaries. Of the consolidated entities described above, the Company is the controlling partner in limited-life partnerships owning two properties having a noncontrolling interest deficit balance of $ 4.9 million. These two partnership agreements contain provisions that require the partnerships to be liquidated through the sale of their assets upon reaching a date specified in each respective partnership agreement. The Company, as controlling partner, has an obligation to cause the property owning partnerships to distribute the proceeds of liquidation to the Noncontrolling Interests in these Partially Owned Properties only to the extent that the net proceeds received by the partnerships from the sale of their assets warrant a distribution based on the partnership agreements. As of December 31, 2022, the Company estimates the value of Noncontrolling Interest distributions for these two properties would have been approximately $ 55.4 million (“Settlement Value”) had the partnerships been liquidated. This Settlement Value is based on estimated third-party consideration realized by the partnerships upon disposition of the two Partially Owned Properties and is net of all other assets and liabilities, including yield maintenance on the mortgages encumbering the properties, that would have been due on December 31, 2022 had those mortgages been prepaid. Due to, among other things, the inherent uncertainty in the sale of real estate assets, the amount of any potential distribution to the Noncontrolling Interests in the Company’s Partially Owned Properties is subject to change. To the extent that the partnerships’ underlying assets are worth less than the underlying liabilities, the Company has no obligation to remit any consideration to the Noncontrolling Interests in these Partially Owned Properties.

Equity Capital And Other Interests [Abstract]
Equity, Capital and Other Interests	3. Equity, Capital and Other Interests The Company refers to “Common Shares” and “Units” (which refer to both OP Units and restricted units) as equity securities for EQR and “General Partner Units” and “Limited Partner Units” as equity securities for ERPOP. To provide a streamlined and more readable presentation of the disclosures for the Company and the Operating Partnership, several sections below refer to the respective terminology for each with the same financial information and separate sections are provided, where needed, to further distinguish any differences in financial information and terminology. The following table presents the changes in the Company’s issued and outstanding Common Shares and Units for the years ended December 31, 2022, 2021 and 2020: 2022 2021 2020 Common Shares Common Shares outstanding at January 1, 375,527,195 372,302,000 371,670,884 Common Shares Issued: Conversion of OP Units 452,532 1,354,208 122,505 Issuance of Common Shares 1,740,550 — — Exercise of share options 468,021 1,710,692 239,695 Employee Share Purchase Plan (ESPP) 66,835 70,702 90,196 Restricted share grants, net 174,575 89,593 178,720 Common Shares outstanding at December 31, 378,429,708 375,527,195 372,302,000 Units Units outstanding at January 1, 12,659,027 13,858,073 13,731,315 Restricted unit grants, net 223,242 155,162 249,263 Conversion of OP Units to Common Shares ( 452,532 ) ( 1,354,208 ) ( 122,505 ) Units outstanding at December 31, 12,429,737 12,659,027 13,858,073 Total Common Shares and Units outstanding at December 31, 390,859,445 388,186,222 386,160,073 Units Ownership Interest in Operating Partnership 3.2 % 3.3 % 3.6 % The following table presents the changes in the Operating Partnership’s issued and outstanding General Partner Units and Limited Partner Units for the years ended December 31, 2022, 2021 and 2020: 2022 2021 2020 General and Limited Partner Units General and Limited Partner Units outstanding at January 1, 388,186,222 386,160,073 385,402,199 Issued to General Partner: Issuance of OP Units 1,740,550 — — Exercise of EQR share options 468,021 1,710,692 239,695 EQR’s Employee Share Purchase Plan (ESPP) 66,835 70,702 90,196 EQR’s restricted share grants, net 174,575 89,593 178,720 Issued to Limited Partners: Restricted unit grants, net 223,242 155,162 249,263 General and Limited Partner Units outstanding at December 31, 390,859,445 388,186,222 386,160,073 Limited Partner Units Limited Partner Units outstanding at January 1, 12,659,027 13,858,073 13,731,315 Limited Partner restricted unit grants, net 223,242 155,162 249,263 Conversion of Limited Partner OP Units to EQR Common Shares ( 452,532 ) ( 1,354,208 ) ( 122,505 ) Limited Partner Units outstanding at December 31, 12,429,737 12,659,027 13,858,073 Limited Partner Units Ownership Interest in Operating Partnership 3.2 % 3.3 % 3.6 % The equity positions of various individuals and entities that contributed their properties to the Operating Partnership in exchange for OP Units, as well as the equity positions of the holders of restricted units, are collectively referred to as the “Noncontrolling Interests – Operating Partnership” and “Limited Partners Capital,” respectively, for the Company and the Operating Partnership. Subject to certain exceptions (including the “book-up” requirements of restricted units), the Noncontrolling Interests – Operating Partnership/Limited Partners Capital may exchange their Units with EQR for Common Shares on a one-for-one basis. The carrying value of the Noncontrolling Interests – Operating Partnership/Limited Partners Capital (including redeemable interests) is allocated based on the number of Noncontrolling Interests – Operating Partnership/Limited Partners Capital in total in proportion to the number of Noncontrolling Interests – Operating Partnership/Limited Partners Capital in total plus the total number of Common Shares/General Partner Units. Net income is allocated to the Noncontrolling Interests – Operating Partnership/Limited Partners Capital based on the weighted average ownership percentage during the period. The Operating Partnership has the right but not the obligation to make a cash payment instead of issuing Common Shares to any and all holders of Noncontrolling Interests – Operating Partnership/Limited Partners Capital requesting an exchange of their Noncontrolling Interests – Operating Partnership/Limited Partners Capital with EQR. Once the Operating Partnership elects not to redeem the Noncontrolling Interests – Operating Partnership/Limited Partners Capital for cash, EQR is obligated to deliver Common Shares to the exchanging holder of the Noncontrolling Interests – Operating Partnership/Limited Partners Capital. The Noncontrolling Interests – Operating Partnership/Limited Partners Capital are classified as either mezzanine equity or permanent equity. If EQR is required, either by contract or securities law, to deliver registered Common Shares, such Noncontrolling Interests – Operating Partnership/Limited Partners Capital are differentiated and referred to as “Redeemable Noncontrolling Interests – Operating Partnership” and “Redeemable Limited Partners,” respectively. Instruments that require settlement in registered shares cannot be classified in permanent equity as it is not always completely within an issuer’s control to deliver registered shares. Therefore, settlement in cash is assumed and that responsibility for settlement in cash is deemed to fall to the Operating Partnership as the primary source of cash for EQR, resulting in presentation in the mezzanine section of the balance sheet. The Redeemable Noncontrolling Interests – Operating Partnership/Redeemable Limited Partners are adjusted to the greater of carrying value or fair market value based on the Common Share price of EQR at the end of each respective reporting period. EQR has the ability to deliver unregistered Common Shares for the remaining portion of the Noncontrolling Interests – Operating Partnership/Limited Partners Capital that are classified in permanent equity at December 31, 2022 and 2021. The carrying value of the Redeemable Noncontrolling Interests – Operating Partnership/Redeemable Limited Partners is allocated based on the number of Redeemable Noncontrolling Interests – Operating Partnership/Redeemable Limited Partners in proportion to the number of Noncontrolling Interests – Operating Partnership/Limited Partners Capital in total. Such percentage of the total carrying value of Units/Limited Partner Units which is ascribed to the Redeemable Noncontrolling Interests – Operating Partnership/Redeemable Limited Partners is then adjusted to the greater of carrying value or fair market value as described above. As of December 31, 2022 and 2021, the Redeemable Noncontrolling Interests – Operating Partnership/Redeemable Limited Partners have a redemption value of approximately $ 318.3 million and $ 499.0 million, respectively, which represents the value of Common Shares that would be issued in exchange for the Redeemable Noncontrolling Interests – Operating Partnership/Redeemable Limited Partners. T he following table presents the changes in the redemption value of the Redeemable Noncontrolling Interests – Operating Partnership/Redeemable Limited Partners for the years ended December 31, 2022, 2021 and 2020, respectively (amounts in thousands): 2022 2021 2020 Balance at January 1, $ 498,977 $ 338,951 $ 463,400 Change in market value ( 176,490 ) 158,598 ( 125,224 ) Change in carrying value ( 4,214 ) 1,428 775 Balance at December 31, $ 318,273 $ 498,977 $ 338,951 Net proceeds from EQR Common Share and Preferred Share (see definition below) offerings and proceeds from exercise of options for Common Shares are contributed by EQR to ERPOP. In return for those contributions, EQR receives a number of OP Units in ERPOP equal to the number of Common Shares it has issued in the equity offering (or in the case of a preferred equity offering, a number of preference units in ERPOP equal in number and having the same terms as the Preferred Shares issued in the equity offering). As a result, the net proceeds from Common Shares and Preferred Shares are allocated for the Company between shareholders’ equity and Noncontrolling Interests – Operating Partnership and for the Operating Partnership between General Partner’s Capital and Limited Partners Capital to account for the change in their respective percentage ownership of the underlying equity. The Company’s declaration of trust authorizes it to issue up to 100,000,000 preferred shares of beneficial interest, $ 0.01 par value per share (the “Preferred Shares”), with specific rights, preferences and other attributes as the Board of Trustees may determine, which may include preferences, powers and rights that are senior to the rights of holders of the Company’s Common Shares. The following table presents the Company’s issued and outstanding Preferred Shares/Preference Units as of December 31, 2022 and 2021: Amounts in thousands Annual Call Dividend Per December 31, December 31, Date (1) Share/Unit (2) 2022 2021 Preferred Shares/Preference Units of beneficial interest, $ 0.01 par value; 100,000,000 shares authorized: 8.29 % Series K Cumulative Redeemable Preferred Shares/Preference 50 per share/unit; 745,600 shares/units issued 12/10/26 $ 4.145 $ 37,280 $ 37,280 $ 37,280 $ 37,280 (1) On or after the call date, redeemable Preferred Shares/Preference Units may be redeemed for cash at the option of the Company or the Operating Partnership, respectively, in whole or in part, at a redemption price equal to the liquidation price per share/unit, plus accrued and unpaid distributions, if any. (2) Dividends on Preferred Shares/Preference Units are payable quarterly. Other EQR and ERPOP currently have an active universal shelf registration statement for the issuance of equity and debt securities that automatically became effective upon filing with the SEC in May 2022 and expires in May 2025. Per the terms of ERPOP’s partnership agreement, EQR contributes the net proceeds of all equity offerings to the capital of ERPOP in exchange for additional OP Units (on a one-for-one Common Share per OP Unit basis) or preference units (on a one-for-one preferred share per preference unit basis). The Company has an At-The-Market (“ATM”) share offering program which allows EQR to issue Common Shares from time to time into the existing trading market at current market prices or through negotiated transactions, including under forward sale arrangements. In May 2022, the Company replaced the prior program with a new program which extended the maturity to May 2025 and gives us the authority to issue up to 13.0 million shares, all of which remain available for issuance as of December 31, 2022. Forward sale agreements under the ATM program allow the Company, at its election, to settle the agreements by issuing Common Shares in exchange for net proceeds at the then-applicable forward sale price specified by the agreement or, alternatively, to settle the agreements in whole or in part through the delivery or receipt of Common Shares or cash. Issuances of shares under these forward sale agreements are classified as equity transactions. Accordingly, no amounts relating to the forward sale agreements are recorded in the consolidated financial statements until settlement occurs. Prior to any settlements, the only impact to the consolidated financial statements is the inclusion of incremental shares, if any, within the calculation of diluted net income per share using the treasury stock method (see Note 11 for additional discussion). The actual forward price per share to be received by the Company upon settlement will be determined on the applicable settlement date based on adjustments made to the initial forward price to reflect the then-current overnight federal funds rate and the amount of dividends paid to holders of the Company’s Common Shares over the term of the forward sale agreement. During the quarter ended September 30, 2021, the Company entered into forward sale agreements under the prior program for a total of approximately 1.7 million Common Shares at a weighted average initial forward price per share of $ 83.25 . During the quarter ended December 31, 2022, the Company settled all of the outstanding forward sale agreements, at a weighted average forward price per share of $ 80.22 , which is inclusive of adjustments made to reflect the then-current federal funds rate and the amount of dividends paid to holders of the Company's Common Shares, for net proceeds of approximately $ 139.6 million. Concurrent with this transaction, ERPOP issued the same amount of OP Units to EQR in exchange for the net proceeds. The Company may repurchase up to 13.0 million Common Shares under its share repurchase program. No open market repurchases have occurred since 2008. As of December 31, 2022 , EQR has remaining authorization to repurchase up to 13.0 million of its shares.

During the year ended December 31, 2021, the Company disposed of the following to unaffiliated parties (sales price in thousands): Properties Apartment Units Sales Price Rental Properties – Consolidated 14 3,053 $ 1,716,775 Total 14 3,053 $ 1,716,775 The Company recognized a net gain on sales of real estate properties of approximately $ 1.1 billion on the above sales. Impairment During the year ended December 31, 2021, the Company recorded an approximate $ 16.8 million non-cash asset impairment charge on a land parcel which is included in land held for development on the consolidated balance sheets and included in the non-same store/other segment discussed in Note 17. The charge was the result of an analysis of the parcel’s estimated fair value (determined using internally developed models based on market assumptions and potential sales data from the marketing process) compared to its current capitalized carrying value after reassessment of our expected hold period for the parcel.

Investments In Partially Owned Entities [Abstract]
Investments in Partially Owned Entities	6. Investments in Partially Owned Entities The Company has invested in various entities with unrelated third parties which are either consolidated or accounted for under the equity method of accounting (unconsolidated). Consolidated VIEs In accordance with accounting standards for consolidation of VIEs, the Company consolidates ERPOP on EQR’s financial statements. As the sole general partner of ERPOP, EQR has exclusive control of ERPOP’s day-to-day management. The limited partners are not able to exercise substantive kick-out or participating rights. As a result, ERPOP qualifies as a VIE. EQR has a controlling financial interest in ERPOP and, thus, is ERPOP’s primary beneficiary. EQR has the power to direct the activities of ERPOP that most significantly impact ERPOP’s economic performance as well as the obligation to absorb losses or the right to receive benefits from ERPOP that could potentially be significant to ERPOP. The Company has various equity interests in certain joint ventures that have been deemed to be VIEs, and the Company is the VIEs’ primary beneficiary. As a result, the joint ventures are required to be consolidated on the Company’s financial statements. The following table summarizes the Company’s consolidated joint ventures as of December 31, 2022 and 2021: Operating Properties (1) Project Under Development (2) Properties Apartment Units Project Apartment Units 2022 Consolidated Joint Ventures (VIE) 15 3,114 1 312 2021 Consolidated Joint Ventures (VIE) 16 3,546 1 312 (1) In 2022, the Company acquired its joint venture partner’s 25 % interest in a 432 -unit apartment property for $ 32.2 million, and the property is now wholly owned.

(2) The land under this project is subject to a long-term ground lease. The following table provides consolidated assets and liabilities related to the VIEs discussed above as of December 31, 2022 and 2021 (amounts in thousands): December 31, 2022 December 31, 2021 Consolidated Assets $ 691,880 $ 912,955 Consolidated Liabilities $ 158,932 $ 251,424 Certain consolidated joint ventures in which we have investments obtained mortgage debt to finance a portion of their activities. The following table and information summarizes the variable rate construction mortgage debt that is non-recourse to the Company at December 31, 2022 and 2021 (aggregate and amounts borrowed under loan commitments in thousands): December 31, 2022 December 31, 2021 Recently Completed Operating Property (1) Project Under Development Recently Completed Operating Property (1) Number of joint ventures with debt financing 1 1 1 Aggregate loan commitments $ 67,589 $ 73,344 $ 67,589 Amounts borrowed under loan commitments (2) $ 64,776 $ 44,980 $ 61,783 Maturity dates 2023 2025 2022 (1) The maturity date of the construction loan was extended to June 25, 2023. (2) See Note 9 for the proceeds of secured conventional floating rate debt under Mortgage Notes Payable . Investments in Unconsolidated Entities The Company has various equity interests in certain joint ventures that are unconsolidated and accounted for using the equity method of accounting. Most of these have been deemed to be VIEs and the Company is not the VIEs' primary beneficiary. The remaining have been deemed not to be VIEs and the Company does not have a controlling voting interest. The following table and information summarizes the Company’s investments in unconsolidated entities as of December 31, 2022 and 2021 (amounts in thousands except for ownership percentage): December 31, 2022 December 31, 2021 Ownership Percentage Investments in Unconsolidated Entities: Various Real Estate Holdings (VIE) $ 35,974 $ 36,024 Varies Projects Under Development and Land Held for Development (VIE) 218,043 72,488 62 % - 95 % (1) Real Estate Technology Funds/Companies (VIE) 25,249 19,347 Varies Other ( 242 ) ( 411 ) Varies Investments in Unconsolidated Entities $ 279,024 $ 127,448 (1) In certain instances, the joint venture agreements contain provisions for promoted interests in favor of our joint venture partner. If the terms of the promoted interest are attained, then our share of the proceeds from a sale or other capital event of the unconsolidated entity may be less than the indicated ownership percentage. The following table summarizes the Company’s unconsolidated joint ventures that were deemed to be VIEs as of December 31, 2022 and 2021: Real Estate Holdings (1) Projects Under Development (2), (5) Projects Held for Development (2), (3) Entities Projects Apartment Units (4) Projects Apartment Units (4) 2022 Unconsolidated Joint Ventures (VIE) 2 6 1,982 3 966 2021 Unconsolidated Joint Ventures (VIE) 1 3 929 3 1,005 (1) Represents entities that hold various real estate investments.

Therefore, the entities are unconsolidated and recorded using the equity method of accounting. See Note 2 for additional discussion. (2) Represents the intended number of apartment units to be developed. In 2021, the Company entered into a strategic partnership with Toll Brothers, Inc. (“Toll”) to develop apartment communities in key markets. The Company and Toll have and expect to continue to enter into separate joint venture agreements for each property, and the Company has and expects to continue to account for these unconsolidated joint ventures under the equity method of accounting. Toll has and will continue to act as the managing member of each project and receive developer fees. The Company, in certain circumstances, may act as the property manager, receive property management fees and have the right, but not the obligation, to acquire each property at fair market value upon stabilization. As of December 31, 2022, the Company and Toll entered into four separate joint venture agreements under the strategic partnership.

Fair Value Measurements

Fair Value Measurements	12 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	10. Fair Value Measurements The valuation of financial instruments requires the Company to make estimates and judgments that affect the fair value of the instruments. The Company, where possible, bases the fair values of its financial instruments on listed market prices and third-party quotes. Where these are not available, the Company bases its estimates on current instruments with similar terms and maturities or on other factors relevant to the financial instruments. In the normal course of business, the Company is exposed to the effect of interest rate changes. The Company may seek to manage these risks by following established risk management policies and procedures including the use of derivatives to hedge interest rate risk on debt instruments. The Company may also use derivatives to manage commodity prices in the daily operations of the business. During the year ended December 31, 2021, the Company purchased and sold investment securities and recognized a net gain on sale of $ 23.4 million, which is included in interest and other income in the consolidated statements of operations. The Company did no t own any of these investment securities at December 31, 2021. A three-level valuation hierarchy exists for disclosure of fair value measurements. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The three levels are defined as follows: • Level 1 – Inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets. • Level 2 – Inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. • Level 3 – Inputs to the valuation methodology are unobservable and significant to the fair value measurement. The Company’s derivative positions are valued using models developed by the respective counterparty as well as models applied internally by the Company that use as their inputs readily observable market parameters (such as forward yield curves and credit default swap data). The following table summarizes the inputs to the valuations for each type of fair value measurement: Fair Value Measurement Type Valuation Inputs Employee holdings (other than Common Shares) within the supplemental executive retirement plan (the “SERP”) Quoted market prices for identical assets. These holdings are included in other assets and other liabilities on the consolidated balance sheets. Redeemable Noncontrolling Interests – Operating Partnership/Redeemable Limited Partners Quoted market price of Common Shares. Mortgage notes payable and private unsecured debt (including its commercial paper and line of credit, if applicable) Indicative rates provided by lenders of similar loans. Public unsecured notes Quoted market prices for each underlying issuance. The fair values of the Company’s financial instruments (other than mortgage notes payable, unsecured notes, commercial paper, line of credit and derivative instruments), including cash and cash equivalents and other financial instruments, approximate their carrying or contract value. The following table provides a summary of the carrying and fair values for the Company’s mortgage notes payable and unsecured debt (including its commercial paper and line of credit, if applicable) at December 31, 2022 and 2021, respectively (amounts in thousands): December 31, 2022 December 31, 2021 Carrying Value Estimated Fair Carrying Value Estimated Fair Mortgage notes payable, net $ 1,953,438 $ 1,803,525 $ 2,191,201 $ 2,193,689 Unsecured debt, net 5,472,284 4,874,490 6,150,252 6,798,309 Total debt, net $ 7,425,722 $ 6,678,015 $ 8,341,453 $ 8,991,998 The following table summarizes the Company’s consolidated derivative instruments at December 31, 2022 (dollar amounts are in thousands): Forward Starting Current Notional Balance $ 450,000 Lowest Interest Rate 2.4470 % Highest Interest Rate 3.6995 % Maturity Date 2033 (1) Forward Starting Swaps – Designed to partially fix interest rates in advance of planned future debt issuances.

In April 2020, the Company paid approximately $ 1.2 million to settle two forward starting swaps in conjunction with the issuance of $ 495.0 million of ten-year secured conventional mortgage notes. The entire $ 1.2 million was initially deferred as a component of accumulated other comprehensive income (loss) and will be recognized as an increase to interest expense over the first five years of the mortgage notes.

Share Incentive Plans

Share Incentive Plans	12 Months Ended
	Dec. 31, 2022
Share-Based Payment Arrangement, Noncash Expense [Abstract]
Share Incentive Plans	12. Share Incentive Plans Any Common Shares issued pursuant to EQR’s incentive equity compensation and employee share purchase plans will result in ERPOP issuing OP Units to EQR on a one-for-one basis with ERPOP receiving the net cash proceeds of such issuances. Overview of Share Incentive Plans The 2019 Share Incentive Plan (the “2019 Plan”), as approved by the Company’s shareholders on June 27, 2019, expires on June 27, 2029 and reserves 11,331,958 Common Shares for issuance. All future awards will be granted under the 2019 Plan. As of December 31, 2022, 8,920,638 shares were available for future issuance. Pursuant to the 2019 Plan and the 2011 Share Incentive Plan (the “2011 Plan”) (collectively the “Share Incentive Plans”), officers, trustees, key employees and consultants of the Company and its subsidiaries may be granted share options to acquire Common Shares (“Options”), including non-qualified share options (“NQSOs”), incentive share options (“ISOs”) and share appreciation rights (“SARs”), or may be granted restricted or non-restricted shares/units (including long-term incentive plan awards), subject to conditions and restrictions. Options, SARs, restricted shares and restricted units are sometimes collectively referred to herein as “Awards.” The 2011 Plan will terminate when all outstanding Awards have expired or have been exercised/vested. The Board of Trustees may at any time amend or terminate the Share Incentive Plans, but termination will not affect Awards previously granted, absent immediate vesting and cash settlement. Any Options which had vested prior to such a termination would remain exercisable by the holder. Employee Long-Term Compensation Awards The following table summarizes the terms of Awards generally granted to employees: Options Restricted Shares Restricted Units Overview Options exercised after vesting result in issuance of new Common Shares. Restricted shareholders generally have the same voting rights and receive quarterly dividend payments on their shares at the same rate and on the same date as any other Common Share holder (1). When certain conditions are met, restricted units convert into an equal number of OP Units, which the holder may exchange for Common Shares on a one-for-one basis or at the option of the Company the cash value of such shares. Restricted unitholders receive quarterly distribution payments on their restricted units at the same rate and on the same date as any other OP Unit holder (1). Grant/Exercise Granted at the fair market value of Common Shares as of the grant date using the Black-Scholes model as described below. Granted at the fair market value of Common Shares as of the grant date. Granted at varying discount rates to the fair market value of Common Shares as of the grant date (2). Vesting Period In three equal installments over a three-year period from the grant date. Three years from the grant date. Three years from the grant date. Expiration Ten years from the grant date. Not applicable. Ten years from the grant date (2). Upon Employee Unvested options are canceled. Unvested restricted shares are canceled. Unvested restricted units are canceled. (1) Dividends/distributions paid on unvested restricted shares and units are included as a component of retained earnings and Noncontrolling Interest – Operating Partnership/Limited Partners Capital, respectively, and have not been considered in reducing net income available to Common Shares/Units in a manner similar to the Company’s preferred share/preference unit dividends for the earnings per share/Unit calculation. (2) A restricted unit will automatically convert to an OP Unit when the capital account of each restricted unit increases (“books-up”) to a specified target. The probability of a book-up occurring within the ten-year contractual life along with the liquidity risk associated with various hold period restrictions are both reflected in the discount. If the capital target is not attained within ten years following the date of issuance, the restricted unit will automatically be canceled and no compensation will be payable to the holder of such canceled restricted unit. If the capital target is attained and the restricted unit is converted to an OP Unit, it will not expire. Valuation Method of Share Options The fair value of the Option grants is recognized over the requisite service/vesting period of the Options. The fair value for the Company’s Options was estimated at the time the Options were granted using the Black-Scholes option pricing model with the primary grant in each year having the following weighted average assumptions: 2022 2021 2020 Expected volatility (1) 21.7 % 21.3 % 15.2 % Expected life (2) 5 years 5 years 5 years Expected dividend yield (3) 3.26 % 3.23 % 3.04 % Risk-free interest rate (4) 1.66 % 0.50 % 1.32 % Exercise price per share (5) $ 91.59 $ 67.48 $ 83.08 Option valuation per share $ 12.57 $ 7.96 $ 7.23 (1) Expected volatility – Estimated based on the historical five-year volatility (the period matching the expected life) of EQR’s share price measured on a monthly basis. (2) Expected life – Approximates the actual weighted average life of all Options granted since the Company went public in 1993. (3) Expected dividend yield – Calculated by averaging the historical annual yield on EQR shares for a period matching the expected life of each grant, with the annual yield calculated by dividing actual regular dividends (excluding any special dividends) by the average price of EQR’s shares in a given year. (4) Risk-free interest rate – The most current U.S. Treasury rate available at the grant date for a period matching the expected life of each grant. (5) Exercise price per share – The closing share price of the Common Shares on the grant date. The valuation method and assumptions are the same as those the Company used in accounting for Option expense in its consolidated financial statements. The Black-Scholes option valuation model was developed for use in estimating the fair value of traded options that have no vesting restrictions and are fully transferable. This model is only one method of valuing options. Because the Company’s Options have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair value estimate, the actual value of the Options to the recipient may be significantly different. Long-Term Incentive Plan The Company’s executive compensation program allows the Chairman, Chief Executive Officer and certain other executive officers to earn from 0 % to 200 % of the target number of long-term incentive (“LTI”) awards, payable in the form of restricted shares and/or restricted units. No payout would be made for any result below 50 % of the target performance metric. The Company’s Total Shareholder Return (“TSR”), Normalized Funds from Operations (“FFO”) and Net Debt to Normalized EBITDAre (Earnings Before Interest, Taxes, Depreciation and Amortization for Real Estate) results over a forward-looking three-year performance period determine the restricted shares and/or restricted units awarded and are compared to pre-established quantitative performance metrics. The grant date fair value of the awards is estimated using a Monte Carlo model for the TSR portion of the awards, and the resulting expense is recorded over the service period regardless of whether the TSR performance measures are achieved, while the Normalized FFO and Net Debt to Normalized EBITDAre portions of the awards are adjusted based on the final achievement obtained. If the executive is retirement-eligible, the grant date fair value is amortized into expense over the first year. All other awards are amortized into expense over the three-year performance and vesting period. If employment is terminated prior to vesting, the restricted shares and restricted units are generally canceled. The LTI participants receive distributions only on restricted units awarded equal to 10 % of the quarterly distributions paid on OP Units during the performance period. At the end of the performance period, LTI participants receive dividends/distributions actually earned on restricted shares or restricted units awarded during the performance period, less any distributions already paid on the restricted units. The grant date fair value of the TSR portion of the LTI awards is estimated using a multifactor Monte Carlo model to determine share prices for a set of relative awards for which the payout of the award depends on the spread of EQR’s TSR to the TSR of two indices: (a) the FTSE Nareit Apartment Index; and (b) the FTSE Nareit Equity Index. The absolute Company TSR metric previously included in the TSR portion of the LTI awards for which the payout of the award only depended on EQR’s TSR was replaced with a Net Debt to Normalized EBITDAre metric for the 2022 LTI plan, covering the three-year performance period from January 1, 2022 through December 31, 2024. The grant date fair value of the Normalized FFO and Net Debt to Normalized EBITDAre portions of the LTI awards are estimated using the closing price of EQR Common Shares on the grant date for the restricted shares and a discounted closing price of EQR Common Shares on the grant date for the restricted units to reflect the “book-up” and liquidity risk inherent in the units. The individual prices determined above are then weighted to arrive at the final values for each restricted share/unit as follows: 2022 2021 2020 Weighted average fair value per restricted share $ 96.84 $ 61.73 $ 75.89 Weighted average fair value per restricted unit $ 93.32 $ 59.82 $ 72.69 The valuation method and assumptions are the same as those the Company used in accounting for the LTI award expense in its consolidated financial statements. The Monte Carlo valuation model is only one method of valuing awards. Because the Company’s restricted shares/units have characteristics significantly different from those of traded shares/units, and because changes in the subjective input assumptions can materially affect the fair value estimate, the actual value of the restricted shares/units to the recipient may be significantly different. Trustees All non-employee Trustees, with the exception of the Company’s Chairman, are granted Options, restricted shares and/or restricted units that vest one year from the grant date that corresponds to the term for which he or she has been elected to serve. Since 2016, the Chairman has only received awards under the LTI plan (see further discussion above). Retirement Benefits The Company’s Share Incentive Plans provide for certain benefits upon retirement. The following table summarizes the terms of each retirement eligibility category. Age 62 for Employees Rule of 70 for Employees Age 72 for Trustees Eligibility For employees hired prior to January 1, 2009 and who were age 59 or older as of February 1, 2019. All employees (1). All non-employee Trustees. Effect on unvested restricted shares, Awards immediately vest, Options continue to be exercisable for the balance of the applicable ten-year option period and restricted units are still subject to the book-up provisions. Awards continue to vest per the original vesting schedule, subject to certain conditions, Options continue to be exercisable for the balance of the applicable ten-year option period and restricted units are still subject to the book-up provisions. Awards immediately vest, Options continue to be exercisable for the balance of the applicable ten-year option period and restricted units are still subject to the book-up provisions. Effect on LTI Plan Awards are prorated in proportion to the number of days worked in the first year of the three-year performance period and the individual does not receive any payout of shares or units until the final payout is determined at the end of the three-year performance period. (1) The Rule of 70 is met when an employee’s years of service with the Company (which must be at least 15 years) plus his or her age (which must be at least 55 years) on the date of termination equals or exceeds 70 years. In addition, the employee must give the Company at least six months’ advance written notice of his or her intention to retire along with agreeing to certain other conditions. Under the Company’s definitions of retirement, some of its executive officers, including its Chief Executive Officer, and its Chairman are retirement eligible. Compensation Expense and Award Activity The following tables summarize compensation information regarding the restricted shares, restricted units, Options and Employee Share Purchase Plan (“ESPP”) for the three years ended December 31, 2022, 2021 and 2020. Year Ended December 31, 2022 Compensation Compensation Restricted Units/Options Compensation Dividends Restricted shares (2) $ 10,419 $ 1,176 $ — $ 11,595 $ 1,120 Restricted units (2) 16,487 87 2,530 19,104 1,039 Options 1,889 169 263 2,321 — ESPP discount 718 78 — 796 — Total $ 29,513 $ 1,510 $ 2,793 $ 33,816 $ 2,159 Year Ended December 31, 2021 Compensation Compensation Restricted Units/Options Compensation Dividends Restricted shares (2) $ 7,258 $ 1,131 $ — $ 8,389 $ 761 Restricted units (2) 16,689 70 1,038 17,797 1,254 Options 2,980 121 — 3,101 — ESPP discount 883 108 — 991 — Total $ 27,810 $ 1,430 $ 1,038 $ 30,278 $ 2,015 Year Ended December 31, 2020 Compensation Compensation Restricted Units/Options Compensation Dividends Restricted shares (2) $ 10,053 $ 1,172 $ — $ 11,225 $ 1,172 Restricted units (2) 10,103 80 1,743 11,926 1,855 Options 2,156 193 — 2,349 — ESPP discount 862 82 — 944 — Total $ 23,174 $ 1,527 $ 1,743 $ 26,444 $ 3,027 (1) The Company allows eligible officers the ability to receive immediately vested restricted units (subject to the book-up provisions described above and a two-year hold restriction) or immediately vested Options in-lieu of any percentage of their annual cash bonus. (2) Includes LTI plan awards granted under the executive compensation program. Compensation expense is generally recognized for Awards as follows: • Restricted shares, restricted units and Options – Straight-line method over the vesting period of the Options, shares or units regardless of cliff or ratable vesting distinctions. • LTI plan awards – Target amount is recognized under the straight-line method over the vesting period of the shares or units. • ESPP discount – Immediately upon the purchase of Common Shares each quarter. The Company accelerates the recognition of compensation expense for all Awards for those individuals approaching or meeting the retirement age criteria discussed above. The total compensation expense related to Awards not yet vested at December 31, 2022 is $ 9.5 million (including the accelerated expenses for individuals approaching or meeting the retirement age criteria discussed above), which is expected to be recognized over a weighted average term of 1.38 yea rs.

Employee Plans	13. Employee Plans The Company established an Employee Share Purchase Plan to provide each employee and trustee the ability to annually acquire up to $ 100,000 of Common Shares of EQR. The Company registered 7,000,000 Common Shares under the ESPP, of which 2,486,599 Common Shares remained available for purchase at December 31, 2022 . The Common Shares may be purchased quarterly at a price equal to 85 % of the lesser of: (a) the closing price for a share on the last day of such quarter; and (b) the greater of: (i) the closing price for a share on the first day of such quarter, and (ii) the average closing price for a share for all the business days in the quarter. The following table summarizes information regarding the Common Shares issued under the ESPP with the net proceeds noted below being contributed to ERPOP in exchange for OP Units (amounts in thousands except share and per share amounts): Year Ended December 31, 2022 2021 2020 Shares issued 66,835 70,702 90,196 Issuance price ranges $ 52.33 – $ 72.51 $ 53.13 – $ 71.04 $ 46.23 – $ 63.84 Issuance proceeds $ 4,178 $ 4,265 $ 4,508 The Company established a defined contribution plan (the “401(k) Plan”) to provide retirement benefits for employees that meet minimum employment criteria. The Company matches dollar for dollar up to the first 4 % of eligible compensation that a participant contributes to the 401(k) Plan for all employees except those defined as highly compensated employees, whose match is 3 %. Participants are vested in the Company’s contributions over five years . The Company recognized an expense in the amount of $ 4.8 million, $ 4.9 million and $ 5.2 million for the years ended December 31, 2022, 2021 and 2020, respectively. The Company established the SERP to provide certain officers and trustees an opportunity to defer a portion of their eligible compensation in order to save for retirement. The SERP is restricted to investments in Common Shares, certain marketable securities that have been specifically approved and cash equivalents. The deferred compensation liability represented in the SERP and the securities issued to fund such deferred compensation liability are consolidated by the Company and carried on the Company’s balance sheets, and the Company’s Common Shares held in the SERP are accounted for as a reduction to paid in capital (included in general partner’s capital in the Operating Partnership’s financial statements).

Commitments and Contingencies	16. Commitments and Contingencies Commitments Real Estate Development Commitments As of December 31, 2022 , the Company has both consolidated and unconsolidated real estate projects under development. The following table summarizes the gross remaining total project costs for the Company’s projects under development at December 31, 2022 (total project costs remaining in thousands): Projects Apartment Units Total Project Costs Remaining (1) Projects Under Development Consolidated 2 537 $ 147,708 Unconsolidated 6 1,982 358,277 Total Projects Under Development 8 2,519 $ 505,985 (1) The Company's share of the $ 506.0 million in total project costs remaining approximate s $ 146.4 million, with the balance funded by the Company's joint venture partners (approximately $ 11.2 million) and/or applicable construction loans (approximately $ 348.4 million). We have entered into, and may continue in the future to enter into, joint venture agreements with third-party partners for the development of multifamily rental properties. The joint venture agreements with each development partner include buy-sell provisions that provide the right, but not the obligation, for the Company to acquire each respective partner’s interests or sell its interests at any time following the occurrence of certain pre-defined events described in the joint venture agreements. See Note 6 for additional discussion. In 2021, the Company entered into a commitment agreement (the “Commitment Agreement”) with Toll to pursue the joint development of multifamily rental properties with an initial term of three years . The Company intends to invest 75 % of the equity for each selected project and Toll intends to invest 25 %. It is expected that each project will also be financed with approximately 60 % non-recourse construction debt. The parties have targeted an initial minimum co-investment of approximately $ 750.0 million in combined equity. The Company and Toll have and expect to continue to enter into separate joint venture agreements for each property, and the Company has and expects to continue to account for these unconsolidated joint ventures under the equity method of accounting. As of December 31, 2022, the Company and Toll have entered into four separate joint venture agreements under the Commitment Agreement, with three projects currently under development. Other Commitments We have entered into, and may continue in the future to enter into, real estate technology and other real estate fund investments. At December 31, 2022 , the Company has invested in eight real estate technology funds and one other real estate investment fund with aggregate remaining commitments of approximately $ 19.9 million . Employment Agreements The Company has entered into a retirement benefits agreement with its Chairman and a deferred compensation agreement with one former executive officer. During the years ended December 31, 2022, 2021 and 2020 , the Company recognized compensation expense of $( 0.2 ) million, $ 0.1 million and $ 0.5 million, respectively, related to these agreements. The following table summarizes the Company’s contractual obligations for deferred compensation for the next five years and thereafter as of December 31, 2022: (Payments) Due by Year (in thousands) 2023 2024 2025 2026 2027 Thereafter Total Other Long-Term Liabilities: Deferred Compensation (1) $ ( 666 ) $ ( 767 ) $ ( 767 ) $ ( 767 ) $ ( 767 ) $ ( 4,220 ) $ ( 7,954 ) (1) Estimated payments to the Company’s Chairman and one former executive officer based on actual and estimated retirement dates. Contingencies Litigation and Legal Matters The Company, as an owner of real estate, is subject to various federal, state and local laws. Compliance by the Company with existing laws has not had a material adverse effect on the Company. However, the Company cannot predict the impact of new or changed laws or regulations on its current properties or on properties that it may acquire in the future. The Company does not believe there is any litigation pending or threatened against it that, individually or in the aggregate, may reasonably be expected to have a material adverse effect on the Company.

Segment Reporting [Abstract]
Reportable Segments	17. Reportable Segments Operating segments are defined as components of an enterprise that engage in business activities from which they may earn revenues and incur expenses and about which discrete financial information is available that is evaluated regularly by the chief operating decision maker. The chief operating decision maker decides how resources are allocated and assesses performance on a recurring basis at least quarterly. The Company’s primary business is the acquisition, development and management of multifamily residential properties, which includes the generation of rental and other related income through the leasing of apartment units to residents. The chief operating decision maker evaluates the Company’s operating performance geographically by market and both on a same store and non-same store basis. While the Company does maintain a non-residential presence, it accounts for approximately 3.7 % of total revenues for the year ended December 31, 2022 and is designed as an amenity for our residential residents. The chief operating decision maker evaluates the performance of each property on a consolidated residential and non-residential basis. The Company’s geographic consolidated same store operating segments represent its reportable segments. The Company’s development activities are other business activities that do not constitute an operating segment and as such, have been aggregated in the “Other” category in the tables presented below. All revenues are from external customers and there is no customer who contributed 10% or more of the Company’s total revenues during the three years ended December 31, 2022, 2021 and 2020, respectively. The primary financial measure for the Company’s rental real estate segment is net operating income (“NOI”), which represents rental income less: 1) property and maintenance expense and 2) real estate taxes and insurance expense (all as reflected in the accompanying consolidated statements of operations and comprehensive income). The Company believes that NOI is helpful to investors as a supplemental measure of its operating performance because it is a direct measure of the actual operating results of the Company’s apartment properties. Revenues for all leases are reflected on a straight-line basis in accordance with GAAP for the current and comparable periods. The following table presents a reconciliation of NOI from our rental real estate for the years ended December 31, 2022, 2021 and 2020, respectively (amounts in thousands): Year Ended December 31, 2022 2021 2020 Rental income $ 2,735,180 $ 2,463,997 $ 2,571,705 Property and maintenance expense ( 483,865 ) ( 453,532 ) ( 440,998 ) Real estate taxes and insurance expense ( 388,412 ) ( 397,105 ) ( 381,562 ) Total operating expenses ( 872,277 ) ( 850,637 ) ( 822,560 ) Net operating income $ 1,862,903 $ 1,613,360 $ 1,749,145 The following tables present NOI from our rental real estate for each segment for the years ended December 31, 2022, 2021 and 2020, respectively, as well as total assets and capital expenditures at December 31, 2022 and 2021, respectively (amounts in thousands): Year Ended December 31, 2022 Year Ended December 31, 2021 Year Ended December 31, 2020 Rental Operating NOI Rental Operating NOI Rental Operating NOI Same store (1) Los Angeles $ 469,180 $ 137,078 $ 332,102 $ 431,954 $ 132,274 $ 299,680 $ 444,129 $ 140,469 $ 303,660 Orange County 122,660 26,338 96,322 109,427 24,986 84,441 105,236 24,545 80,691 San Diego 86,728 19,395 67,333 78,709 18,395 60,314 74,737 18,176 56,561 Subtotal - Southern California 678,568 182,811 495,757 620,090 175,655 444,435 624,102 183,190 440,912 San Francisco 418,941 124,952 293,989 383,817 118,795 265,022 435,371 117,085 318,286 Washington, D.C. 411,975 136,130 275,845 389,205 129,065 260,140 405,571 125,353 280,218 New York 434,820 186,896 247,924 367,370 182,631 184,739 424,534 197,740 226,794 Seattle 282,902 79,101 203,801 256,988 80,775 176,213 257,372 74,362 183,010 Boston 262,604 79,979 182,625 235,050 76,374 158,676 240,158 71,611 168,547 Denver 43,767 12,422 31,345 39,084 11,209 27,875 37,917 11,040 26,877 Total same store 2,533,577 802,291 1,731,286 2,291,604 774,504 1,517,100 2,425,025 780,381 1,644,644 Non-same store/other Non-same store (2) 179,707 70,654 109,053 59,629 27,691 31,938 11,791 2,706 9,085 Other (3) 21,896 ( 668 ) 22,564 112,764 48,442 64,322 134,889 39,473 95,416 Total non-same store/other 201,603 69,986 131,617 172,393 76,133 96,260 146,680 42,179 104,501 Totals $ 2,735,180 $ 872,277 $ 1,862,903 $ 2,463,997 $ 850,637 $ 1,613,360 $ 2,571,705 $ 822,560 $ 1,749,145 (1) For the years ended December 31, 2022 and 2021 , same store primarily includes all properties acquired or completed that were stabilized prior to January 1, 2021, less properties subsequently sold, which represented 72,872 apartment units.

Summary Of Significant Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation Due to the Company’s ability as general partner to control either through ownership or by contract the Operating Partnership and its subsidiaries, the Operating Partnership and each such subsidiary has been consolidated with the Company for financial reporting purposes, except for any unconsolidated properties/entities.
Real Estate Assets And Depreciation Of Investment In Real Estate	Real Estate Assets and Depreciation of Investment in Real Estate The Company expects that substantially all of its acquisitions will be accounted for as asset acquisitions. In an asset acquisition, the Company is required to capitalize transaction costs and allocate the purchase price on a relative fair value basis (including any identified intangible assets). For the years ended December 31, 2022 and 2021, all acquisitions were considered asset acquisitions. In making estimates of relative fair values for purposes of allocating purchase price, the Company utilizes a number of sources, including independent appraisals that may be obtained in connection with the acquisition or financing of the respective property, our own analysis of recently acquired or developed and existing comparable properties in our portfolio and other market data. The Company also considers information obtained about each property as a result of its pre-acquisition due diligence, marketing and leasing activities in estimating the relative fair value of the tangible and intangible assets/liabilities acquired. The Company allocates the purchase price of acquired real estate to various components as follows: • Land – Based on actual purchase price adjusted to an allocation of the relative fair value (as necessary) if acquired separately or market research/comparables if acquired with an operating property. • Furniture, Fixtures and Equipment – Based on an estimate of the allocation of the relative fair value of the appliances and fixtures inside an apartment unit. The per-apartment unit amount applied depends on the economic age of the apartment units acquired. Depreciation is calculated on the straight-line method over an estimated useful life of five to ten years . • Lease Intangibles – The Company considers the value of acquired in-place leases and above/below market leases and the amortization period is the average remaining term of each respective acquired lease. • Other Intangible Assets – The Company considers whether it has acquired other intangible assets, including any customer relationship intangibles and the amortization period is the estimated useful life of the acquired intangible asset. • Building – Based on the allocation of the relative fair value determined on an “as-if vacant” basis. Depreciation is calculated on the straight-line method over an estimated useful life of thirty years . • Long-Term Debt – The Company calculates the allocation of the relative fair value by discounting the remaining contractual cash flows on each instrument at the current market rate for those borrowings. Replacements inside an apartment unit such as appliances and carpeting are depreciated over an estimated useful life of five to ten years . Expenditures for ordinary maintenance and repairs are expensed to operations as incurred and significant renovations and building improvements that improve and/or extend the useful life of the asset are capitalized over their estimated useful life, generally five to fifteen years . Initial direct leasing costs are expensed as incurred as such expense approximates the deferral and amortization of initial direct leasing costs over the lease terms. The Company classifies real estate assets as real estate held for sale when it is probable a property will be disposed of. The Company classifies properties under development and/or expansion and properties in the lease-up phase (including land) as construction-in-progress until construction has been completed and certificates of occupancy permits have been obtained.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets At least quarterly, the Company evaluates its long-lived assets, including its investment in real estate, for indicators of impairment. The judgments regarding the existence of impairment indicators are based on factors such as operational performance, market conditions, legal, regulatory and environmental concerns, the Company’s intent and ability to hold the related asset, as well as any significant cost overruns on development properties. Future events could occur which would cause the Company to conclude that impairment indicators exist and an impairment loss is warranted. If an impairment indicator exists, the Company performs the following: • For long-lived operating assets to be held and used, the Company compares the expected future undiscounted cash flows for the long-lived asset against the carrying amount of that asset. If the sum of the estimated undiscounted cash flows is less than the carrying amount of the asset, the Company would make an estimate of the fair value for the particular asset and would record an impairment loss for the difference between the estimated fair value and the carrying amount of the asset. In determining the future undiscounted cash flows or the estimated fair value of an asset there is judgment in estimating the expected future rental revenues, operating expenses and discount and capitalization rates. • For long-lived non-operating assets (projects under development and land held for development), management evaluates major cost overruns, market conditions that could affect lease-up projections, intent and ability to hold the asset, and any other indicators of impairment. If any of the indicators were to suggest impairment was present, a recoverability analysis would be performed and the carrying value of the asset would be adjusted accordingly to fair value. • For long-lived assets to be disposed of, an impairment loss is recognized when the estimated fair value of the asset, less the estimated cost to sell, is less than the carrying amount of the asset measured at the time that the Company has determined it will sell the asset. Long-lived assets held for sale and the related liabilities are separately reported, with the long-lived assets reported at the lower of their carrying amounts or their estimated fair values, less their costs to sell, and are not depreciated after reclassification to real estate held for sale. See Note 4 for further discussion of the Company’s impairment charge on a land parcel in 2021.
Impairment of Investments in Unconsolidated Entities and Other Investments	Impairment of Investments in Unconsolidated Entities and Other Investments At least quarterly, the Company evaluates its investments in unconsolidated entities and other investments for indicators of other than temporary impairment, considering whether there has been a change to events or circumstances that would impact recoverability of the Company’s investment as well as any changes with regards to the Company's intent and ability to hold the investment to recover its carrying value.
Cost Capitalization	Cost Capitalization See the Real Estate Assets and Depreciation of Investment in Real Estate section for a discussion of the Company’s policy with respect to capitalization vs. expensing of fixed asset/repair and maintenance costs. For all development, capital and renovation projects, the Company uses its professional judgment in determining whether such costs meet the criteria for capitalization or must be expensed as incurred. The Company capitalizes interest, real estate taxes and insurance, as well as payroll for those individuals directly responsible for and who spend their time on the execution and supervision of development activities. Additionally, the Company capitalizes payroll for those individuals directly responsible for and who spend their time on the execution and supervision of major capital and/or renovation projects. Capitalization ends when the asset, or a portion of the asset, is substantially completed and ready for its intended use. These costs are reflected on the balance sheets as increases to depreciable property and/or construction-in-progress. During the years ended December 31, 2022 and 2021, the Company capitalized $ 15.6 mil lion and $ 13.9 million, respectively, of payroll and associated costs of employees directly responsible for and who spend their time on the execution and supervision of development activities as well as major capital and/or renovation projects.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all demand deposits, money market accounts and investments in certificates of deposit with a maturity of three months or less at the date of purchase to be cash equivalents. The Company maintains its cash and cash equivalents at financial institutions. The combined account balances at one or more institutions typically exceed the Federal Deposit Insurance Corporation (“FDIC”) insurance coverage, and, as a result, there is a concentration of credit risk related to amounts on deposit in excess of FDIC insurance coverage. The Company believes that the risk is not significant, as the Company does not anticipate the financial institutions’ non-performance.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The valuation of financial instruments requires the Company to make estimates and judgments that affect the fair value of the instruments. The Company, where possible, bases the fair values of its financial instruments on listed market prices and third-party quotes. Where these are not available, the Company bases its estimates on current instruments with similar terms and maturities or on other factors relevant to the financial instruments. In the normal course of business, the Company is exposed to the effect of interest rate changes. The Company may seek to manage these risks by following established risk management policies and procedures, including the use of derivatives to hedge interest rate risk on debt instruments. The Company may also use derivatives to manage commodity prices in the daily operations of the business. The Company has a policy of only entering into derivative contracts with major financial institutions based upon their credit ratings and other factors. When viewed in conjunction with the underlying and offsetting exposure that the derivatives are designed to hedge, the Company has not sustained a material loss from these instruments nor does it anticipate any material adverse effect on its net income or financial position in the future. The Company recognizes all derivatives as either assets or liabilities in the consolidated balance sheets and measures those instruments at fair value. In addition, fair value adjustments will affect either shareholders’ equity/partners’ capital or net income depending on whether the derivative instruments qualify as a hedge for accounting purposes and, if so, the nature of the hedging activity. When the terms of an underlying transaction are modified, or when the underlying transaction is terminated or completed, all changes in the fair value of the instrument are marked-to-market with changes in value included in net income each period until the instrument matures. Any derivative instrument used for risk management that does not meet the hedging criteria is marked-to-market each period. The Company does not use derivatives for trading or speculative purposes. See Note 10 for additional derivatives discussion.
Leases and Revenue Recognition	Leases and Revenue Recognition Rental income attributable to residential leases is recorded on a straight-line basis over the term of the lease when reasonably assured they are collectible, which is not materially different than if it were recorded when due from residents and recognized monthly as it was earned. Residential apartment leases may include lease income related to such items as utility recoveries, parking rent, storage rent and pet rent that the Company treats as a single lease component because the amenities cannot be leased on their own and the timing and pattern of revenue recognition are the same. Leases entered into between a resident and a property for the rental of an apartment unit are generally year-to-year, renewable upon consent of both parties on an annual or monthly basis. Rental income attributable to non-residential leases is also recorded on a straight-line basis over the term of the lease when reasonably assured they are collectible. Non-residential leases may include lease income related to such items as utility recoveries, parking rent and storage rent that the Company treats as a single lease component because the amenities cannot be leased on their own and the timing and pattern of revenue recognition are the same. Non-residential leases generally have five to ten year lease terms with market-based renewal options and consist of ground floor retail spaces and master-leased parking garages that serve as additional amenities for our residents. The majority of the Company’s revenue is derived from residential, non-residential and other lease income. Our revenue streams have the same timing and pattern of revenue recognition across our reportable segments, with consistent allocations between the lease and revenue recognition standards. The Company elected an accounting policy to account for both its lease and non-lease components (specifically common area maintenance charges) as a single lease component under the lease standard. The Company is a lessor for its residential and non-residential leases and is a lessee for its corporate headquarters and regional offices and ground leases for land underlying current operating properties or projects under development. If applicable, lease agreements must be evaluated to determine the accounting treatment as a finance or operating lease in accordance with the lease standard. The lease standard also requires lessees to recognize on the balance sheet: (a) a liability for the lease obligation (initially measured at the present value of the future lease payments not yet paid over the lease term); and (b) an asset for its right to use the underlying asset (initially equal to the lease liability). The Company uses estimates and judgments on the discount rate used to calculate the present value of the future lease payments. The Company uses its incremental borrowing rate as the discount rate because the Company typically cannot readily determine the rate implicit in the lease. Since the Company’s credit backs the corporate office lease obligations and the lease terms are generally ten years or less, the discount rate range was estimated by using the Company’s borrowing rates for actual pricing data. The discount rate range for ground leases takes into account various factors, including the longer life of the ground leases, and was estimated by using the Company’s borrowing rates for actual pricing data through 30 years and other long-term market rates. The Company’s revenue streams that are not accounted for under the lease standard include: • Parking revenue – The Company’s parking revenue, not related to leasing, is derived primarily from monthly and transient daily parking and is accounted for at the point in time when control of the goods or services transfers to the customer and our performance obligation is satisfied. • Other rental and non-rental related revenue – The Company receives other income, including, but not limited to: (a) ancillary income, such as laundry, renters insurance and cable income; (b) net settlement income; and (c) miscellaneous fee income. • Fee and asset management revenue and interest income – The Company’s fee and asset management revenue and interest income are recorded on an accrual basis. • Gains or losses on sales of real estate properties – The Company accounts for the sale of real estate properties and any related gain recognition in accordance with the accounting guidance applicable to sales of real estate, which establishes standards for recognition of profit on all real estate sales transactions. The Company recognizes the sale and associated gain or loss from the disposition when control transfers to unrelated third parties, contingencies have been removed and sufficient cash consideration has been received by the Company. See Note 8 for the Company’s rental income detail allocated between the lease and revenue recognition standards. The Company’s allowance for doubtful accounts (which offsets accounts receivable and is included within other assets on the consolidated balance sheets) and bad debts (which reduce rental income on the consolidated statements of operations and comprehensive income) have historically been very modest, particularly in our residential business, given the quality of our resident base and asset class. However, due to the impact of the novel coronavirus (“COVID-19”) pandemic and extended eviction moratoriums enacted during the pandemic, the allowance for doubtful accounts and bad debts became elevated during 2020 and remained elevated in 2021 and 2022. In accordance with the lease standard, if we determine the lease payments are not probable of collection (based on known troubled accounts, rent deferral plans granted, historical experience and other currently available evidence), we fully reserve for any unpaid amounts, deferred rent receivable, variable lease payments and straight-line receivable balances and recognize rental income only if cash is received. If the Company’s estimates of collectibility differ from the cash received, then the timing and amount of the Company’s reported revenue could be impacted. See Note 8 for additional details.
Share-Based Compensation	Share-Based Compensation The Company expenses share-based compensation for employee and trustee grants of restricted shares, restricted units and share options. Any common share of beneficial interest, $ 0.01 par value per share (the “Common Shares”), issued pursuant to EQR’s incentive equity compensation and employee share purchase plans will result in ERPOP issuing units of partnership interest (“OP Units”) to EQR on a one-for-one basis, with ERPOP receiving the net cash proceeds of such issuances. See Note 12 for further discussion.
Income and Other Taxes	Income and Other Taxes EQR has elected to be taxed as a REIT. This, along with the nature of the operations of its operating properties, resulted in no provision for federal income taxes at the EQR level. In addition, ERPOP generally is not liable for federal income taxes as the partners should recognize their allocable share of income or loss in their tax returns; therefore no provision for federal income taxes has been made at the ERPOP level. Historically, the Company has generally only incurred certain state and local income, excise and franchise taxes. The Company has elected taxable REIT subsidiary status for certain of its corporate subsidiaries and, as a result, these entities will incur both federal and state income taxes on any taxable income of such entities after consideration of any net operating losses. The Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) included tax provisions which increased allowable interest expense deductions for 2020 (no increases for 2021 and 2022) and increased the ability for taxpayers to use net operating losses. These provisions did not result in a material impact to the Company’s taxable income or tax liabilities. The CARES Act also allowed corporations to request accelerated refunds of their alternative minimum tax (“AMT”) credit. Prior to enactment of this provision, the remaining credits would have been refunded in installments in 2020, 2021 and 2022. We received a refund of our remaining $ 1.6 million in AMT credits during the year ended December 31, 2020. The Company’s provision for income and other tax expense (benefit) was as follows for the years ended December 31, 2022, 2021 and 2020 (amounts in thousands): Year Ended December 31, 2022 2021 2020 State and local income, franchise and excise tax (benefit) $ 900 $ 915 $ 852 Income and other tax expense (benefit) (1) $ 900 $ 915 $ 852 (1) All provisions for income tax amounts are current and none are deferred. During the years ended December 31, 2022, 2021 and 2020, the tax character of the Company’s dividends and distributions were as follows: Year Ended December 31, 2022 (1) 2021 (2) 2020 (3) Tax character of dividends and distributions: Ordinary dividends $ 1.75466 $ 1.40791 $ 1.34739 Long-term capital gain 0.42850 0.73687 0.77923 Unrecaptured section 1250 gain 0.29434 0.26522 0.24838 Dividends and distributions per Common Share/Unit outstanding $ 2.47750 $ 2.41000 $ 2.37500 (1) The Company’s fourth quarter 2022 dividends and distributions of $ 0.625 per Common Share/Unit outstanding will be included as taxable income in calendar year 2023. (2) The Company’s fourth quarter 2021 dividends and distributions of $ 0.6025 per Common Share/Unit outstanding was included as taxable income in calendar year 2022. (3) The Company’s fourth quarter 2020 dividends and distributions of $ 0.6025 per Common Share/Unit outstanding was included as taxable income in calendar year 2021. The Company issued Internal Revenue Service (“IRS”) Form 1099-DIV to shareholders to report the tax character of Company distributions consistent with these amounts. The Company provides additional information to assist shareholders in the preparation of their tax returns. For 2022, the Company reported an AMT preference adjustment equal to $( 0.01 ) per share a nd disclosed amounts defined under Treasury Regulation §1.1061-6(c) as “One Year Amounts Disclosure” and “Three Year Amounts Disclosure” equal to $ 0.00979 per share and $ 0.00000 per share, resp ectively.
Principals of Consolidation	Principles of Consolidation The Company may hold an interest in subsidiaries, partnerships, joint ventures and other similar entities and accounts for these interests in accordance with the consolidation guidance. The Company first determines whether to consolidate the entity as a variable interest entity (“VIE”) or voting interest entity, or to account for the interest under the equity method of accounting as an unconsolidated entity. In situations in which we have concluded that an entity qualifies as a VIE, it is generally because the equity investors of VIEs do not have sufficient equity at risk to finance their activities without additional subordinated financial support or do not have substantive voting rights. The Company consolidates an entity when it is considered to be the primary beneficiary of the VIE or when it controls the entity through ownership of a majority voting interest. A primary beneficiary has the power to direct the activities that most significantly impact the VIE’s performance and has the obligation to absorb the expected losses or the right to receive the expected residual returns that could potentially be significant to the VIE. In evaluating whether the entity is a VIE and/or the Company is the primary beneficiary of the entity, the Company considers several factors, including, but not limited to, proportionate share or ownership of the VIE, funding and financing sources, the business purpose of the entity, related parties, developer and property management fees and agreement terms regarding major decisions, participating and voting rights, contributions and distributions.
Investments in Unconsolidated Entities	Investments in Unconsolidated Entities The Company accounts for investments in unconsolidated entities under the equity method of accounting and measures the investments initially at cost. The Company subsequently adjusts the carrying amount by additional cash and non-cash contributions and distributions and its proportionate share of the earnings and losses of such entities. The proportionate share of the earnings and losses are also recognized in the consolidated statements of operations and comprehensive income. In addition, we may earn fees for providing property management services or construction oversight.
Noncontrolling Interests	Noncontrolling Interests A noncontrolling interest in a subsidiary (minority interest) is an ownership interest in the consolidated entity that should be reported as equity in the consolidated financial statements and separate from the parent company’s equity. In addition, consolidated net income is required to be reported at amounts that include the amounts attributable to both the parent and the noncontrolling interest and the amount of consolidated net income attributable to the parent and the noncontrolling interest are required to be disclosed on the face of the consolidated statements of operations and comprehensive income. See Note 3 for further discussion. Operating Partnership: Net income is allocated to noncontrolling interests based on their respective ownership percentage of the Operating Partnership. The ownership percentage is calculated by dividing the number of OP Units held by the noncontrolling interests by the total OP Units held by the noncontrolling interests and EQR. Issuance of additional Common Shares and OP Units changes the ownership interests of both the noncontrolling interests and EQR. Such transactions and the related proceeds are treated as capital transactions. Partially Owned Properties: The Company reflects noncontrolling interests in partially owned properties on the balance sheet for the portion of properties consolidated by the Company that are not wholly owned by the Company. The earnings or losses from those properties attributable to the noncontrolling interests are generally based on ownership percentage and are reflected as noncontrolling interests in partially owned properties in the consolidated statements of operations and comprehensive income. Partners’ Capital The “Limited Partners” of ERPOP include various individuals and entities that contributed their properties to ERPOP in exchange for OP Units. The “General Partner” of ERPOP is EQR. Net income is allocated to the Limited Partners based on their respective ownership percentage of ERPOP. The ownership percentage is calculated by dividing the number of OP Units held by the Limited Partners by the total OP Units held by the Limited Partners and the General Partner. Issuance of additional Common Shares and OP Units changes the ownership interests of both the Limited Partners and EQR. Such transactions and the related proceeds are treated as capital transactions. Redeemable Noncontrolling Interests – Operating Partnership / Redeemable Limited Partners The Company classifies Redeemable Noncontrolling Interests – Operating Partnership / Redeemable Limited Partners in the mezzanine section of the consolidated balance sheets for the portion of OP Units that EQR is required, either by contract or securities law, to deliver registered Common Shares to the exchanging OP Unit holder. The redeemable noncontrolling interest units / redeemable limited partner units are adjusted to the greater of carrying value or fair market value based on the Common Share price of EQR at the end of each respective reporting period. See Note 3 for further discussion.
Use of Estimates	Use of Estimates In preparation of the Company’s financial statements in conformity with accounting principles generally accepted in the United States, management makes 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 as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In August 2020, the Financial Accounting Standards Board (“FASB”) issued an amendment to the debt and equity financial instruments standards which simplifies the accounting for convertible instruments and accounting for contracts in an entity’s own equity. The Company adopted the standard when effective on January 1, 2022 and it had no impact on its consolidated results of operations and financial position. In March 2020, the FASB issued an amendment to the reference rate reform standard which provides the option for a limited period of time to ease the potential burden in accounting for, or recognizing the effects of, reference rate reform on contract modifications and hedge accounting. The new standard was effective for the Company upon issuance and elections could be made through December 31, 2024. The Company elected to apply the hedge accounting expedients and 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. In April 2020, a FASB staff question and answer document was issued which intended to reduce the challenges of evaluating the enforceable rights and obligations of leases for concessions granted to lessees in response to the COVID-19 pandemic. We elected not to evaluate whether qualifying concessions provided by the Company in response to the COVID-19 pandemic are a lease modification, subject to the criteria that the total payments under the amended lease cannot result in a substantial increase in the rights of the lessor or obligations of the lessee. We also elected to treat the concessions as though they were contemplated as part of the existing contracts and therefore will not apply lease modification rules to the qualifying lease concession amendments. As such, deferrals deemed collectible are recorded as rental receivables with no change to timing of rental revenues and deferrals deemed non-collectible and abatements reduce rental revenues in the deferral/abatement period and cause rental revenues to effectively follow a cash basis related to the changes. The accounting elections provided by the FASB mainly apply to the Company’s non-residential leases and the majority of the amendments will not require a straight-line adjustment. See Note 8 for additional discussion. In June 2016, the FASB issued a standard which requires companies to adopt a new approach for estimating credit losses on certain types of financial instruments, such as trade and other receivables and loans. The standard requires entities to estimate a lifetime expected credit loss for most financial instruments, including trade receivables. In November 2018, the FASB issued an amendment excluding operating lease receivables accounted for under the lease standard from the scope of the credit losses standard. The Company adopted this standard as required effective January 1, 2020, and it did not have a material effect on its consolidated results of operations and financial position.
Other	Other The Company is the controlling partner in various consolidated partnerships ow ning 15 properties consisting of 3,114 ap artment units having a noncontrolling interest deficit balance of $ 0.7 million at December 31, 2022 . The Company is required to make certain disclosures regarding noncontrolling interests in consolidated limited-life subsidiaries. Of the consolidated entities described above, the Company is the controlling partner in limited-life partnerships owning two properties having a noncontrolling interest deficit balance of $ 4.9 million. These two partnership agreements contain provisions that require the partnerships to be liquidated through the sale of their assets upon reaching a date specified in each respective partnership agreement. The Company, as controlling partner, has an obligation to cause the property owning partnerships to distribute the proceeds of liquidation to the Noncontrolling Interests in these Partially Owned Properties only to the extent that the net proceeds received by the partnerships from the sale of their assets warrant a distribution based on the partnership agreements. As of December 31, 2022, the Company estimates the value of Noncontrolling Interest distributions for these two properties would have been approximately $ 55.4 million (“Settlement Value”) had the partnerships been liquidated. This Settlement Value is based on estimated third-party consideration realized by the partnerships upon disposition of the two Partially Owned Properties and is net of all other assets and liabilities, including yield maintenance on the mortgages encumbering the properties, that would have been due on December 31, 2022 had those mortgages been prepaid. Due to, among other things, the inherent uncertainty in the sale of real estate assets, the amount of any potential distribution to the Noncontrolling Interests in the Company’s Partially Owned Properties is subject to change. To the extent that the partnerships’ underlying assets are worth less than the underlying liabilities, the Company has no obligation to remit any consideration to the Noncontrolling Interests in these Partially Owned Properties.

Share Based Compensation Arrangement By Share Based Payment Award [Line Items]
Summary of Terms of Awards Generally Granted to Employees	The following table summarizes the terms of Awards generally granted to employees: Options Restricted Shares Restricted Units Overview Options exercised after vesting result in issuance of new Common Shares. Restricted shareholders generally have the same voting rights and receive quarterly dividend payments on their shares at the same rate and on the same date as any other Common Share holder (1). When certain conditions are met, restricted units convert into an equal number of OP Units, which the holder may exchange for Common Shares on a one-for-one basis or at the option of the Company the cash value of such shares. Restricted unitholders receive quarterly distribution payments on their restricted units at the same rate and on the same date as any other OP Unit holder (1). Grant/Exercise Granted at the fair market value of Common Shares as of the grant date using the Black-Scholes model as described below. Granted at the fair market value of Common Shares as of the grant date. Granted at varying discount rates to the fair market value of Common Shares as of the grant date (2). Vesting Period In three equal installments over a three-year period from the grant date. Three years from the grant date. Three years from the grant date. Expiration Ten years from the grant date. Not applicable. Ten years from the grant date (2). Upon Employee Unvested options are canceled. Unvested restricted shares are canceled. Unvested restricted units are canceled. (1) Dividends/distributions paid on unvested restricted shares and units are included as a component of retained earnings and Noncontrolling Interest – Operating Partnership/Limited Partners Capital, respectively, and have not been considered in reducing net income available to Common Shares/Units in a manner similar to the Company’s preferred share/preference unit dividends for the earnings per share/Unit calculation. (2) A restricted unit will automatically convert to an OP Unit when the capital account of each restricted unit increases (“books-up”) to a specified target. The probability of a book-up occurring within the ten-year contractual life along with the liquidity risk associated with various hold period restrictions are both reflected in the discount. If the capital target is not attained within ten years following the date of issuance, the restricted unit will automatically be canceled and no compensation will be payable to the holder of such canceled restricted unit. If the capital target is attained and the restricted unit is converted to an OP Unit, it will not expire.
Summary of Valuation Method of Share Options	The fair value of the Option grants is recognized over the requisite service/vesting period of the Options. The fair value for the Company’s Options was estimated at the time the Options were granted using the Black-Scholes option pricing model with the primary grant in each year having the following weighted average assumptions: 2022 2021 2020 Expected volatility (1) 21.7 % 21.3 % 15.2 % Expected life (2) 5 years 5 years 5 years Expected dividend yield (3) 3.26 % 3.23 % 3.04 % Risk-free interest rate (4) 1.66 % 0.50 % 1.32 % Exercise price per share (5) $ 91.59 $ 67.48 $ 83.08 Option valuation per share $ 12.57 $ 7.96 $ 7.23 (1) Expected volatility – Estimated based on the historical five-year volatility (the period matching the expected life) of EQR’s share price measured on a monthly basis. (2) Expected life – Approximates the actual weighted average life of all Options granted since the Company went public in 1993. (3) Expected dividend yield – Calculated by averaging the historical annual yield on EQR shares for a period matching the expected life of each grant, with the annual yield calculated by dividing actual regular dividends (excluding any special dividends) by the average price of EQR’s shares in a given year. (4) Risk-free interest rate – The most current U.S. Treasury rate available at the grant date for a period matching the expected life of each grant. (5) Exercise price per share – The closing share price of the Common Shares on the grant date.
Summary of Weighted Average Fair Value for Each Restricted Share/Unit	The individual prices determined above are then weighted to arrive at the final values for each restricted share/unit as follows: 2022 2021 2020 Weighted average fair value per restricted share $ 96.84 $ 61.73 $ 75.89 Weighted average fair value per restricted unit $ 93.32 $ 59.82 $ 72.69
Summary of Terms of Each Retirement Eligibility Category	The following table summarizes the terms of each retirement eligibility category.
