Cybersecurity Risk Management, Strategy, and Governance [Line Items]
Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	Item 1C. Cybersecurity Risk management and strategy We have an enterprise-wide information security program designed to protect our information systems from cybersecurity threats. We identify and assess risks from cybersecurity threats by monitoring and evaluating our digital assets and our risk profile using various methods. We monitor security events that are internally discovered or externally reported that may affect our systems and have processes and procedures to assess those events for potential cybersecurity impact or risk and consequently improve our security measures and planning. Additionally, we work with third parties from time to time that assist us in refining our cybersecurity risk strategy in order to identify, assess and manage cybersecurity risks, including professional services firms and consulting firms. We seek to detect and investigate unauthorized attempts and attacks against our network and services, and to minimize their occurrence and recurrence through changes or updates to our internal processes and tools and changes or updates to our services; however, we remain potentially vulnerable to known or unknown threats. Our cybersecurity incident response processes are designed to escalate certain cybersecurity events to members of management depending on the circumstances. Key members of management, including representatives from information technology ("IT"), operations, legal, finance, risk management and internal audit, serve on the Company’s senior security incident response team to help the Company mitigate and remediate cybersecurity incidents of which they are notified, and certain cybersecurity incidents are escalated to the Company’s executives. In addition, the Company’s incident response processes include potential reporting to the Audit Committee of our Board of Trustees for certain cybersecurity incidents. We also have a third-party risk management program in place to manage cybersecurity risks associated with third-party service providers . While we do maintain processes and procedures to identify, prioritize and assess risks associated with third-party service providers , we must rely on third parties to augment our security program, and we cannot ensure in all circumstances that their efforts will be successful. While to date we have not experienced a cybersecurity threat or incident that resulted in a material adverse impact to our business or operations, there can be no guarantee that we will not experience such an incident in the future. Any significant disruption to our systems could adversely affect our business and results of operations. Further, a cyber incident impacting our systems or a third-party’s systems could subject us to business, regulatory, litigation and reputational risk, which could have a negative effect on our business, financial condition and results of operations. Notwithstanding the extensive approach we take to cybersecurity, we may not be successful in preventing or mitigating a cybersecurity incident that could have a material adverse effect on us. While we maintain cybersecurity insurance, the costs related to cybersecurity threats or disruptions may not be fully insured. See Item 1A, Risk Factors , for a discussion of cybersecurity risks. Governance Our Information Technology Security Team, under the oversight of our Senior Vice President and Chief Technology Officer and the leadership of our VP of IT Infrastructure and Security, is responsible for our overall information security strategy, policy, security engineering, operations and cyber threat detection and response. The Information Technology Security Team manages and continually enhances a robust enterprise security structure with the ultimate goal of minimizing cybersecurity incidents to the extent feasible , while simultaneously increasing our system resilience in an effort to minimize the business impact should an incident occur. Our Information Technology Security Team possesses decades of experience in navigating cybersecurity threats and mitigating associated risks as a result of holding similar positions at other large companies. Most members of the team hold degrees in cybersecurity and/or related disciplines, have cybersecurity certifications such as Certified Information Systems Security Professional (CISSP) and/or periodically attend various cyber-focused conferences and training programs. Specifically, our Senior Vice President and Chief Technology Officer and our VP of IT Infrastructure and Security combined have over 30 years of technology and cybersecurity experience. T he team provides regular reports to senior management and affected departments on various cybersecurity threats, assessments and findings. The Audit Committee of our Board of Trustees oversees our annual enterprise risk management assessment, where we assess key risks within the Company, including security and technology risks and cybersecurity threats. The Audit Committee oversees our ongoing cybersecurity risk management efforts and regularly receives detailed reports from representatives of our Information Technology Security Team addressing a wide range of related topics. At least annually, our IT leadership (and external cybersecurity experts if applicable) reviews key cybersecurity strategies and policies with the full Board of Trustees, including risk assessments, mitigation strategies, areas of emerging risks, incidents and industry trends and other areas of importance.

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, 2024 and 2023, all acquisitions were considered asset acquisitions. In making estimates of relative fair value 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 and/or market research/comparables, adjusted to an allocation of the relative fair value. • Furniture, Fixtures and Equipment – Based on replacement cost, which approximates the allocation of the relative fair value. 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 or real estate tax 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 . • Site Improvements – Based on replacement cost, which approximates the allocation of the relative fair value. Depreciation is calculated on the straight-line method over an estimated useful life of eight 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 evaluates whether the expected future undiscounted cash flows exceed the carrying amount of the asset. If they do not, the Company estimates the fair value for the asset and records an impairment loss for the difference between the carrying amount and the estimated fair value. • For long-lived non-operating assets (projects under development and land held for development), 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 is probable that the asset will be disposed of. 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. 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, construction-in-progress and/or investments in unconsolidated entities. During the years ended December 31, 2024 and 2023, the Company capitalized $ 16.9 mil lion and $ 15.4 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 9 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 and/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 income 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; and (b) 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 7 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 pandemic and extended eviction moratoriums enacted during the pandemic, the allowance for doubtful accounts and bad debts were elevated in 2022, 2023 and 2024, though they have gradually declined throughout 2023 and 2024. 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 we later determine that these lease payments are probable of collection (based on sustained clean payment history, no deferral plans granted and other currently available evidence), we will no longer fully reserve for the respective current receivable balances, we will reinstate the straight-line balances for the respective leases and we will no longer 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 7 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 11 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 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 Company’s provision for income and other tax expense (benefit) was as follows for the years ended December 31, 2024, 2023 and 2022 (amounts in thousands): December 31, 2024 2023 2022 State and local income, franchise and excise tax (benefit) $ 1,256 $ 1,148 $ 900 Income and other tax expense (benefit) (1) $ 1,256 $ 1,148 $ 900 (1) All provisions for income tax amounts are current and none are deferred. During the years ended December 31, 2024, 2023 and 2022, the tax character of the Company’s dividends and distributions were as follows: December 31, 2024 (1) 2023 (2) 2022 (3) Tax character of dividends and distributions: Ordinary dividends $ 1.53095 $ 1.85676 $ 1.75466 Long-term capital gain 0.70884 0.57857 0.42850 Unrecaptured section 1250 gain 0.44771 0.17717 0.29434 Dividends and distributions per Common Share/Unit outstanding $ 2.68750 $ 2.61250 $ 2.47750 (1) The Company’s fourth quarter 2024 dividends and distributions of $ 0.675 per Common Share/Unit outstanding will be included as taxable income in calendar year 2025. (2) The Company’s fourth quarter 2023 dividends and distributions of $ 0.6625 per Common Share/Unit outstanding was included as taxable income in calendar year 2024. (3) The Company’s fourth quarter 2022 dividends and distributions of $ 0.625 per Common Share/Unit outstanding was included as taxable income in calendar year 2023. 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 2024, the Company reported an Alternative Minimum Tax ("AMT") preference adjustment equal to $( 0.04 ) 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 $ 0.06866 per share and $ 0.05462 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. Issuances and retirements of Common Shares and OP Units changes the ownership interests of both the noncontrolling interests and EQR. Such transactions and the related proceeds/payments 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. Issuances and retirements of Common Shares and OP Units changes the ownership interests of both the Limited Partners and EQR. Such transactions and the related proceeds/payments 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 November 2024, the Financial Accounting Standards Board (“FASB”) issued a new standard on disaggregation of income statement expenses, which requires an entity to disclose, on an annual and interim basis, disaggregated information about certain income statement expense line items in a tabular format in the notes to the financial statements. The standard will be effective for annual reporting periods beginning after December 15, 2026 and for interim reporting periods within annual reporting periods beginning after December 15, 2027, with early adoption permitted, and may be applied either prospectively or retrospectively. The Company is currently evaluating the impact of the new rules on its disclosures. In March 2024, the Securities and Exchange Commission ("SEC") adopted final rules that will require certain climate-related information in registration statements and annual reports. In April 2024, the SEC voluntarily stayed the new rules as a result of pending legal challenges. The new rules include a requirement to disclose material climate-related risks, descriptions of board and management oversight and risk management activities, the material impacts of these risks on a registrant’s strategy, business model and outlook, and any material climate-related targets or goals, as well as material effects and costs of severe weather events and other natural conditions and greenhouse gas emissions. Prior to the stay of the new rules, they would have been effective for annual periods beginning January 1, 2025, except for the greenhouse gas emissions disclosures, which would have been effective for annual periods beginning January 1, 2026. The Company is currently evaluating the impact of the new rules on its disclosures. In December 2023, the FASB issued an amendment to the income tax standards which requires disclosure enhancements and further transparency to certain income tax disclosures, most notably the tax rate reconciliation and income taxes paid. The new standard will be effective for annual periods beginning January 1, 2025 and will be applied on a prospective basis with the option to apply the standard retrospectively. Due to the nature of the Company's operations and its status as a REIT, we expect the adoption of the standard to have no impact on its disclosures. See the Income and Other Taxes section above for additional discussion. In November 2023, the FASB issued an amendment to the segment reporting standards which requires disclosure for each reportable segment, on an interim and annual basis, of the significant expense categories and amounts that are regularly provided to the chief operating decision maker and included in each reported measure of a segment’s profit or loss. Additionally, it requires disclosure of the title and position of the individual or the name of the group or committee identified as the chief operating decision maker. The Company adopted the standard as required in this Annual Report on Form 10-K for the year ended December 31, 2024. See Note 16 for further discussion. In August 2020, the 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. Other The Company is the controlling partner in various consolidated partnerships ow ning 12 properties consisting of 2,656 ap artment units having a noncontrolling interest deficit balance of $ 0.7 million at December 31, 2024 . 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 $ 1.5 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, 2024, the Company estimates the value of Noncontrolling Interest distributions for these two properties would have been approximately $ 51.7 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, 2024 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 th

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, 2024, 2023 and 2022: 2024 2023 2022 Common Shares Common Shares outstanding at January 1, 379,291,417 378,429,708 375,527,195 Common Shares Issued: Conversion of OP Units 210,200 1,013,795 452,532 Issuance of Common Shares — — 1,740,550 Exercise of share options 375,436 495,690 468,021 Employee Share Purchase Plan (ESPP) 65,198 68,136 66,835 Restricted share grants, net 185,584 148,474 174,575 Common Shares Other: Repurchased and retired ( 652,452 ) ( 864,386 ) — Common Shares outstanding at December 31, 379,475,383 379,291,417 378,429,708 Units Units outstanding at January 1, 11,581,306 12,429,737 12,659,027 Restricted unit grants, net 172,667 165,364 223,242 Conversion of OP Units to Common Shares ( 210,200 ) ( 1,013,795 ) ( 452,532 ) Units outstanding at December 31, 11,543,773 11,581,306 12,429,737 Total Common Shares and Units outstanding at December 31, 391,019,156 390,872,723 390,859,445 Units Ownership Interest in Operating Partnership 3.0 % 3.0 % 3.2 % 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, 2024, 2023 and 2022: 2024 2023 2022 General and Limited Partner Units General and Limited Partner Units outstanding at January 1, 390,872,723 390,859,445 388,186,222 Issued to General Partner: Issuance of OP Units — — 1,740,550 Exercise of EQR share options 375,436 495,690 468,021 EQR’s Employee Share Purchase Plan (ESPP) 65,198 68,136 66,835 EQR’s restricted share grants, net 185,584 148,474 174,575 Issued to Limited Partners: Restricted unit grants, net 172,667 165,364 223,242 General Partner Other: OP Units repurchased and retired ( 652,452 ) ( 864,386 ) — General and Limited Partner Units outstanding at December 31, 391,019,156 390,872,723 390,859,445 Limited Partner Units Limited Partner Units outstanding at January 1, 11,581,306 12,429,737 12,659,027 Limited Partner restricted unit grants, net 172,667 165,364 223,242 Conversion of Limited Partner OP Units to EQR Common Shares ( 210,200 ) ( 1,013,795 ) ( 452,532 ) Limited Partner Units outstanding at December 31, 11,543,773 11,581,306 12,429,737 Limited Partner Units Ownership Interest in Operating Partnership 3.0 % 3.0 % 3.2 % 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, 2024 and 2023. 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, 2024 and 2023, the Redeemable Noncontrolling Interests – Operating Partnership/Redeemable Limited Partners have a redemption value of approximately $ 338.6 million and $ 289.2 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. The 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, 2024, 2023 and 2022, respectively (amounts in thousands): 2024 2023 2022 Balance at January 1, $ 289,248 $ 318,273 $ 498,977 Change in market value 49,366 ( 7,667 ) ( 176,490 ) Change in carrying value ( 51 ) ( 21,358 ) ( 4,214 ) Balance at December 31, $ 338,563 $ 289,248 $ 318,273 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, 2024 and 2023: Amounts in thousands Annual Call Dividend Per December 31, December 31, Date (1) Share/Unit (2) 2024 2023 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; 343,100 shares/units issued 745,600 shares/units issued 12/10/2026 $ 4.145 $ 17,155 $ 37,280 $ 17,155 $ 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. (3) During the year ended December 31, 2024 , the Company repurchased and retired 402,500 Series K Preferred Shares/Preference Units with a liquidation value of approximately $ 20.1 million for total cash consideration of approximately $ 21.8 million, inclusive of premiums and accrued dividends through the redemption date. As a result of this partial redemption, the Company incurred a cash charge of approximately $ 1.4 million which was recorded as a premium on the redemption of Preferred Shares/Preference Units. 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. The current program matures in 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, 2024. 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 10). 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 part of the year ended December 31, 2022, the Company had forward sale agreements outstanding for 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. During the year ended December 31, 2024 , the Company repurchased and subsequently retired approximately $ 38.5 million ( 652,452 shares at a weighted average price per share of $ 58.95 ) of its Common Shares in the open market under its share repurchase program. Concurrent with these transactions, ERPOP repurchased and retired the same amount of OP Units previously issued to EQR. Prior to the share repurchase activity during the year ended December 31, 2024 , the Company had the authority to repurchase up to 13.0 million Common Shares under its share repurchase program, of which 12,347,548 shares remain authorized to repurchase as of December 31, 2024. During the year ended December 31, 2023 , the Company repurchased and subsequently retired approximately $ 49.1 million ( 864,386 shares at a weighted average price per share of $ 56.79 ) of its Common Shares in the open market under its share repurchase program. Concurrent with these transactions, ERPOP repurchased and retired the same amount of OP Units previously issued to EQR. As of December 31, 2023 , EQR had remaining authorization to repurchase up to 12,135,614 of its shares. Following this share repurchase activity, in early 2024 the Company's Board of Trustees approved replenishing the Company's share repurchase program authorization back to its original 13.0 million shares. During the year ended December 31, 2023 , ERPOP issued $ 0.9 million of 3.00 % Series Q Cumulative Redeemable Preference Units (the "Series Q Preference Units") in connection with the buyout of the noncontrolling interest in a consolidated operating property. The 933,454 Series Q Preference Units have a liquidation value of $ 1.00 per unit and pay distributions quarterly at the annual rate of $ 0.03 per unit. The Series Q Preference Units can be redeemed for, at EQR's/ERPOP's option, Common Shares, OP Units and/or cash upon the occurrence of specific events laid out in the agreement. If redeemed for Common Shares or OP Units, the number of shares/units issued is based on the Common Share price. The Series Q Preference Units increased the balance of Noncontrolling Interests - Partially Owned Properties in the consolidated balance sheets.

Investments In Partially Owned Entities [Abstract]
Investments in Partially Owned Entities	5. 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, 2024 and 2023: Operating Properties (1) Projects Under Development (2) Projects Held for Development (2), (3) Properties Apartment Units Projects Apartment Units (4) Projects Apartment Units (4) 2024 Consolidated Joint Ventures (VIE) 12 2,656 1 440 — — 2023 Consolidated Joint Ventures (VIE) 14 3,060 — — 1 440 (1) The land parcel under one of the properties in 2023 is subject to a long-term ground lease. (2) Represents separate consolidated joint ventures for the purpose of developing multifamily rental properties. (3) Represents separate consolidated joint ventures that have not yet started. (4) Represents the intended number of apartment units to be developed. The following table provides consolidated assets and liabilities related to the Company's VIEs as of December 31, 2024 and 2023 (amounts in thousands): December 31, 2024 December 31, 2023 Consolidated Assets $ 528,076 $ 599,788 Consolidated Liabilities $ 47,137 $ 41,153 During the years ended December 31, 2024 and 2023, the Company completed the following transactions: 2024 • Acqu ired its joint venture partner’s 8.0 % interest in a 312 -unit apartment property for $ 3.1 million in cash (the Company had previously repaid the $ 67.9 million construction mortgage during 2023; see further discussion below). The property is now wholly owned. In connection with the buyout, the carrying amount of the Noncontrolling Interests – Partially Owned Properties totaling $ 4.2 million was reduced to zero and the remaining $ 1.1 million was recorded to paid in capital/General Partner's Capital; and • Sold one partially owned property consisting of 92 apartment units for approximately $ 29.5 million. 2023 • Acquired its joint venture partner's 10.0 % interest in a 200 -unit apartment property for $ 4.6 million, of which the Company paid $ 3.7 million in cash and ERPOP issued $ 0.9 million of 3.00 % Series Q Preference Units (see Note 3 for additional discussion). The property is now wholly owned. In connection with the buyout, the carrying amount of the Noncontrolling Interests – Partially Owned Properties totaling $ 3.7 million was reduced to zero and the remaining $ 0.9 million was recorded to paid in capital/General Partner's Capital. The Company also repaid $ 64.7 million of mortgage debt at par prior to maturity in conjunction with the buyout; • Repaid the $ 67.9 million outstanding principal balance of the variable rate construction mortgage for one of its consolidated development joint ventures; • Sold one partially owned property consisting of 166 apartment units for approximately $ 60.1 million; and • Entered into an amended joint venture agreement for one of the unconsolidated projects held for development for the purpose of making the Company the joint venture manager and responsible for funding any further budgeted project costs up to a $ 139.0 million commitment as preferred and mezzanine contributions. The project is now consolidated. There was no funding at the closing of the amended joint venture. See the supplemental information in the consolidated statements of cash flows for disclosure of the consolidated amounts. 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, 2024 and 2023 (amounts in thousands except for ownership percentage): December 31, 2024 December 31, 2023 Ownership Percentage Investments in Unconsolidated Entities: Various Real Estate Holdings (VIE) $ 34,510 $ 35,421 Varies Projects Under Development and Land Held for Development (VIE) 323,998 220,192 62 % - 95 % (1) Real Estate Technology Funds/Companies (VIE) 28,276 26,691 Varies Other ( 253 ) ( 255 ) Varies Investments in Unconsolidated Entities $ 386,531 $ 282,049 (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, 2024 and 2023: Operating Properties (1) Real Estate Holdings (2) Projects Under Development (3), (4) Projects Held for Development (3), (5) Properties Apartment Units Entities Projects Apartment Units (6) Projects Apartment Units (6) 2024 Unconsolidated Joint Ventures (VIE) 4 1,262 3 4 1,359 2 526 2023 Unconsolidated Joint Ventures (VIE) — — 3 6 1,982 4 1,164 (1) The land parcel under one of these properties is subject to a long-term ground lease.

Fair Value Disclosures [Abstract]
Fair Value Measurements	9. 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. 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 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. Derivatives Readily observable market parameters such as forward yield curves and credit default swap data. The fair values of the Company’s financial instruments (other than the items listed above and the investments disclosed below) 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, 2024 and 2023, respectively (amounts in thousands): December 31, 2024 December 31, 2023 Carrying Value Estimated Fair Carrying Value Estimated Fair Mortgage notes payable, net $ 1,630,690 $ 1,506,955 $ 1,632,902 $ 1,509,706 Unsecured debt, net 6,491,055 6,036,591 5,757,548 5,346,488 Total debt, net $ 8,121,745 $ 7,543,546 $ 7,390,450 $ 6,856,194 The following tables provide a summary of the fair value measurements for each major category of assets and liabilities measured at fair value on a recurring basis and the location within the accompanying consolidated balance sheets at December 31, 2024 and 2023, respectively (amounts in thousands): Fair Value Measurements at Reporting Date Using Description Balance Sheet 12/31/2024 Quoted Prices in Significant Other Significant Assets Supplemental Executive Retirement Plan Other Assets $ 109,935 $ 109,935 $ — $ — Liabilities Supplemental Executive Retirement Plan Other Liabilities $ 109,935 $ 109,935 $ — $ — Redeemable Noncontrolling Interests – Operating Partnership/Redeemable Limited Partners Mezzanine $ 338,563 $ — $ 338,563 $ — Fair Value Measurements at Reporting Date Using Description Balance Sheet 12/31/2023 Quoted Prices in Significant Other Significant Assets Supplemental Executive Retirement Plan Other Assets $ 108,478 $ 108,478 $ — $ — Liabilities Supplemental Executive Retirement Plan Other Liabilities $ 108,478 $ 108,478 $ — $ — Redeemable Noncontrolling Interests – Operating Partnership/Redeemable Limited Partners Mezzanine $ 289,248 $ — $ 289,248 $ — The following tables provide a summary of the effect of cash flow hedges on the Company’s accompanying consolidated statements of operations and comprehensive income for the years ended December 31, 2024, 2023 and 2022, respectively (amounts in thousands): December 31, 2024 Amount of Location of Amount of Derivatives designated as hedging instruments: Interest Rate Contracts: Forward Starting Swaps $ ( 3,989 ) Interest expense $ ( 2,499 ) Total $ ( 3,989 ) $ ( 2,499 ) December 31, 2023 Amount of Location of Amount of Derivatives designated as hedging instruments: Interest Rate Contracts: Forward Starting Swaps $ 4,514 Interest expense $ ( 3,737 ) Total $ 4,514 $ ( 3,737 ) December 31, 2022 Amount of Location of Amount of Derivatives designated as hedging instruments: Interest Rate Contracts: Forward Starting Swaps $ 20,654 Interest expense $ ( 11,071 ) Total $ 20,654 $ ( 11,071 ) As of December 31, 2024 and 2023, there were approximate ly $ 4.2 million and $ 5.7 mil lion in deferred gains, net, included in accumulated other comprehensive income (loss), respectively, related to previously settled and/or unsettled derivative instruments, of which an estimated $ 1.2 million may be recognized as additional interest expense during the twelve months ending December 31, 2025. During the year ended December 31, 2024 , the Company paid approximately $ 4.0 million to settle four forward starting swaps in conjunction with the issuance of $ 600.0 million of ten-year unsecured public notes. The entire $ 4.0 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 ten-year term of the notes. During the year ended December 31, 2023 , the Company received a net $ 27.1 million to settle nine forward starting swaps in conjunction with the interest rate lock on $ 530.0 million of ten-year secured conventional mortgage notes. The Company ultimately closed on $ 550.0 million of secured notes. The accrued interest of approximately $ 1.9 million was recorded as a decrease to interest expense. The remaining $ 25.2 million was initially deferred as a component of accumulated other comprehensive income (loss) and will be recognized as a decrease to interest expense over the first nine years and eight months of the mortgage notes. Other The Company has invested in various equity securities without readily determinable fair values and has elected to measure them using the measurement alternative in accordance with the applicable accounting standards for equity securities. These investments are carried at cost less any impairment and adjusted to fair value if there are observable price changes for an identical or similar investment of the same issuer.

Share Incentive Plans

Share Incentive Plans	12 Months Ended

Share-Based Payment Arrangement, Noncash Expense [Abstract]
Share Incentive Plans	11. 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 until its expiration. As of December 31, 2024, 7,554,970 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 unexpired 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: 2024 2023 2022 Expected volatility (1) 23.6 % 23.8 % 21.7 % Expected life (2) 5 years 5 years 5 years Expected dividend yield (3) 3.48 % 3.30 % 3.26 % Risk-free interest rate (4) 3.80 % 4.04 % 1.66 % Exercise price per share (5) $ 60.96 $ 66.59 $ 91.59 Option valuation per share $ 11.01 $ 12.67 $ 12.57 (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 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”) per share 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 per share 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, subject to the retirement benefit provisions discussed below as well as the death and disability provisions of the plan. 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 grant date fair value of the Normalized FFO per share 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: 2024 2023 2022 Weighted average fair value per restricted share $ 62.64 $ 61.18 $ 96.84 Weighted average fair value per restricted unit $ 59.70 $ 58.78 $ 93.32 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 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. 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).

Employee Plans	12. 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 2,353,265 C ommon Shares remained available for purchase at December 31, 2024 . 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, 2024 2023 2022 Shares issued 65,198 68,136 66,835 Issuance price ranges $ 50.60 – $ 62.11 $ 47.97 – $ 55.11 $ 52.33 – $ 72.51 Issuance proceeds $ 3,522 $ 3,517 $ 4,178 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 $ 5.1 million, $ 5.2 million and $ 4.8 million for the years ended December 31, 2024, 2023 and 2022, 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).

Distribution Reinvestment And Share Purchase Plan [Abstract]
Distribution Reinvestment Plan	13. Distribution Reinvestment Plan On September 30, 2014, the Company filed with the SEC a Form S-3 Registration Statement to register 4,790,000 Common Shares pursuant to a Distribution Reinvestment Plan (the “2014 DRIP”), which included the remaining shares available for issuance under a previous registration. The registration was automatically declared effective the same day and will expire when all 4,790,000 shares have been issued. The Company ha s 4,608,156 Common Shares available for issuance under the 2014 DRIP at December 31, 2024. The 2014 DRIP provides holders of record and beneficial owners of Common Shares and Preferred Shares with a simple and convenient method of reinvesting cash dividends/distributions in additional Common Shares. Common Shares purchased under the 2014 DRIP may, at the option of EQR, be directly issued by EQR or purchased by EQR’s transfer agent in the open market using participants’ funds. The net proceeds from any Common Share issuances are contributed to ERPOP in exchange for OP Units.

Related Party Transactions [Abstract]
Transactions with Related Parties	14. Transactions with Related Parties The Company leases its corporate headquarters from an entity affiliated with Samuel Zell, who was EQR's Chairman of the Board of Trustees until his death in May 2023. This lease is no longer a related party lease as of December 31, 2024 and 2023. The lease term expires on November 30, 2032 and contains two five-year extension options. The amount incurred for such office space for the years ended December 31, 2024, 2023 and 2022 were approximately $ 1.9 million , $ 1.9 million and $ 1.7 million, respectively. The Company believes these amounts approximate market rates for such rental space.

Commitments and Contingencies	15. Commitments and Contingencies Commitments Real Estate Development Commitments As of December 31, 2024 , 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, 2024 (total project costs remaining in thousands): Projects Apartment Units Total Project Costs Remaining (1) Projects Under Development Consolidated 2 665 $ 123,087 Unconsolidated 4 1,359 206,583 Total Projects Under Development 6 2,024 $ 329,670 (1) The Company's share of the $ 329.7 million in total project costs remaining approximates $ 172.1 million, with the balance funded by the Company's joint venture partners (approximately $ 2.6 million) and/or applicable construction loans (approximately $ 155.0 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 5 for additional discussion. Other Commitments We have entered into, and may continue in the future to enter into, real estate technology and other real estate fund investments. As of December 31, 2024 , the Company has invested in ten separate such investments totaling $ 42.7 million with aggregate remaining commitments of approximately $ 15.3 million. Employment Agreements The Company entered into a retirement benefits agreement with its former Chairman and a deferred compensation agreement with one former executive officer. During the years ended December 31, 2024, 2023 and 2022 , the Company recognized compensation expense of $ 0.2 million, $ 0.6 million and $( 0.2 ) 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, 2024: (Payments) Due by Year (in thousands) 2025 2026 2027 2028 2029 Thereafter Total Other Long-Term Liabilities: Deferred Compensation (1) $ ( 840 ) $ ( 840 ) $ ( 840 ) $ ( 840 ) $ ( 840 ) $ ( 2,939 ) $ ( 7,139 ) (1) Includes payments due to the estate of the Company’s former Chairman. As of December 31, 2024 and 2023, no payments remain due to the Company's former executive officer. 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 is involved in various pending and threatened legal proceedings which arise in the ordinary course of business. The Company evaluates these litigation matters on an ongoing basis, but in no event less than quarterly, in assessing the adequacy of its accruals and disclosures. For legal proceedings in which it has been determined that a loss is both probable and reasonably estimable, the Company records new accruals and/or adjusts existing accruals that represent its best estimate of the loss incurred based on the facts and circumstances known at that time. As of December 31, 2024 and December 31, 2023, the Company’s litigation accruals approximat ed $ 42.4 million and $ 17.1 million, respectively, and are included in other liabilities in the consolidated balance sheets. Actual losses may differ materially from the amounts noted above and the ultimate outcome of these legal proceedings is generally not yet determinable. As of December 31, 2024 and December 31, 2023, the Company does not believe there is any litigation pending or threatened against it that, either individually or in the aggregate and inclusive of the matters accrued for as noted above, may reasonably be expected to have a material adverse effect on the Company and its financial condition. The Company has been named as a defendant in a number of cases filed in late 2022 and 2023 alleging antitrust violations by RealPage, Inc., a seller of revenue management software products, and various owners and/or operators of multifamily housing, including us, that have utilized these products. The complaints allege collusion among the defendants to illegally fix and inflate the pricing of multifamily rents and seek monetary damages, injunctive relief, fees and costs. All of the cases except for one have been consolidated into a single putative class action in the United States District Court for the Middle District of Tennessee. On December 28, 2023, motions to dismiss this consolidated action, filed by RealPage, Inc. as well as us and our multifamily co-defendants, were denied by the Court and the case is proceeding. Another case with similar allegations has been filed by the District of Columbia against RealPage, Inc. and a number of multifamily owners and/or operators, including us, and no assurance can be given that similar additional cases will not be filed in the future. We believe these various lawsuits are without merit and we intend to vigorously defend against them. As these proceedings are in the early stages, it is not possible for the Company to predict the outcome nor is it possible to estimate the amount of loss, if any, which may be associated with an adverse decision in any of these cases. The Company is named as a defendant in a class action in the United States District Court for the Northern District of California filed in 2016 which alleges that the amount of late fees charged by the Company were improperly determined under California law. The plaintiffs are seeking monetary damages and other relief. On April 8, 2024, the Court issued certain findings of facts and conclusions of law that are adverse to the Company’s legal position. At this time, the Company is continuing to defend the action. While the resolution of this matter cannot be predicted with certainty, the Company does not believe that the eventual outcome will have a material adverse effect on the Company and its financial condition.

Reportable Segments

Segment Reporting [Abstract]
Reportable Segments	16. 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, who is the Company’s chief executive officer, 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 of our apartment communities geographically by market on a same store basis and in total on a non-same store basis, which represent our operating segments. The Company has aggregated its geographic same store operating segments into one reportable segment called same store. Management believes the properties in the same store reportable segment have similar economic characteristics, facilities, services and residents, which is in alignment with the required aggregation criteria. The following reflects the two reportable segments for the Company: • Same store primarily includes all properties acquired or completed that were stabilized (defined as having achieved 90 % physical occupancy for three consecutive months) for all of the current and comparable periods presented. • Non-same store primarily includes all properties acquired during the current and prior year, any properties in lease-up and not stabilized for all of the current and comparable periods presented and any properties undergoing major renovations. The Company has non-residential activities included in each of its reportable segments, which account for less than 4.0 % of total revenues for the year ended December 31, 2024 and serve as an amenity for our residential residents. All revenues are from external customers and there is no customer who contributed 10% or more of the Company’s total revenues during the years ended December 31, 2024, 2023 and 2022, respectively. The primary financial measure for the Company’s reportable segments 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 net income per the consolidated statements of operations to NOI for the years ended December 31, 2024, 2023 and 2022, respectively (amounts in thousands): December 31, 2024 December 31, 2023 December 31, 2022 Net income $ 1,070,975 $ 868,488 $ 806,995 Adjustments: Property management 132,739 119,804 110,304 General and administrative 61,653 60,716 58,710 Depreciation 952,191 888,709 882,168 Net (gain) loss on sales of real estate properties ( 546,797 ) ( 282,539 ) ( 304,325 ) Interest and other income ( 30,329 ) ( 22,345 ) ( 2,193 ) Other expenses 74,051 29,419 13,664 Interest: Expense incurred, net 285,735 269,556 282,920 Amortization of deferred financing costs 7,834 8,941 8,729 Income and other tax expense (benefit) 1,256 1,148 900 (Income) loss from investments in 8,974 5,378 5,031 Total NOI $ 2,018,282 $ 1,947,275 $ 1,862,903 The following table presents NOI from our rental real estate for the years ended December 31, 2024, 2023 and 2022, respectively (amounts in thousands): December 31, 2024 December 31, 2023 December 31, 2022 Rental Operating NOI Rental Operating NOI Rental Operating NOI Same store (1) Los Angeles $ 479,711 $ 148,030 $ 331,681 $ 466,980 $ 143,983 $ 322,997 $ 450,635 $ 132,858 $ 317,777 Orange County 125,214 28,208 97,006 121,113 26,759 94,354 122,660 26,511 96,149 San Diego 96,969 21,127 75,842 92,847 20,794 72,053 86,728 19,506 67,222 Subtotal - Southern California 701,894 197,365 504,529 680,940 191,536 489,404 660,023 178,875 481,148 San Francisco 431,323 129,084 302,239 424,547 128,742 295,805 415,173 124,192 290,981 Washington, D.C. 438,914 137,786 301,128 419,628 132,610 287,018 417,210 138,570 278,640 New York 494,060 201,857 292,203 476,319 193,311 283,008 434,820 187,218 247,602 Boston 327,134 94,576 232,558 314,929 91,977 222,952 270,899 82,523 188,376 Seattle 285,539 81,843 203,696 278,170 78,418 199,752 281,959 79,037 202,922 Denver 71,061 21,600 49,461 71,067 21,328 49,739 67,785 19,569 48,216 Other Expansion Markets 73,493 30,366 43,127 74,593 31,713 42,880 61,897 27,618 34,279 Total same store 2,823,418 894,477 1,928,941 2,740,193 869,635 1,870,558 2,609,766 837,602 1,772,164 Non-same store 100,419 36,350 64,069 35,474 15,117 20,357 74,379 29,758 44,621 Total reportable segments 2,923,837 930,827 1,993,010 2,775,667 884,752 1,890,915 2,684,145 867,360 1,816,785 Other (2) 56,271 30,999 25,272 98,297 41,937 56,360 51,035 4,917 46,118 Totals $ 2,980,108 $ 961,826 $ 2,018,282 $ 2,873,964 $ 926,689 $ 1,947,275 $ 2,735,180 $ 872,277 $ 1,862,903 (1) For the years ended December 31, 2024 and 2023, same store represented 75,299 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, 2024 and 2023, all acquisitions were considered asset acquisitions. In making estimates of relative fair value 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 and/or market research/comparables, adjusted to an allocation of the relative fair value. • Furniture, Fixtures and Equipment – Based on replacement cost, which approximates the allocation of the relative fair value. 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 or real estate tax 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 . • Site Improvements – Based on replacement cost, which approximates the allocation of the relative fair value. Depreciation is calculated on the straight-line method over an estimated useful life of eight 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 evaluates whether the expected future undiscounted cash flows exceed the carrying amount of the asset. If they do not, the Company estimates the fair value for the asset and records an impairment loss for the difference between the carrying amount and the estimated fair value. • For long-lived non-operating assets (projects under development and land held for development), 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 is probable that the asset will be disposed of. 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.
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, construction-in-progress and/or investments in unconsolidated entities. During the years ended December 31, 2024 and 2023, the Company capitalized $ 16.9 mil lion and $ 15.4 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 9 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 and/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 income 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; and (b) 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 7 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 pandemic and extended eviction moratoriums enacted during the pandemic, the allowance for doubtful accounts and bad debts were elevated in 2022, 2023 and 2024, though they have gradually declined throughout 2023 and 2024. 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 we later determine that these lease payments are probable of collection (based on sustained clean payment history, no deferral plans granted and other currently available evidence), we will no longer fully reserve for the respective current receivable balances, we will reinstate the straight-line balances for the respective leases and we will no longer 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 7 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 11 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 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 Company’s provision for income and other tax expense (benefit) was as follows for the years ended December 31, 2024, 2023 and 2022 (amounts in thousands): December 31, 2024 2023 2022 State and local income, franchise and excise tax (benefit) $ 1,256 $ 1,148 $ 900 Income and other tax expense (benefit) (1) $ 1,256 $ 1,148 $ 900 (1) All provisions for income tax amounts are current and none are deferred. During the years ended December 31, 2024, 2023 and 2022, the tax character of the Company’s dividends and distributions were as follows: December 31, 2024 (1) 2023 (2) 2022 (3) Tax character of dividends and distributions: Ordinary dividends $ 1.53095 $ 1.85676 $ 1.75466 Long-term capital gain 0.70884 0.57857 0.42850 Unrecaptured section 1250 gain 0.44771 0.17717 0.29434 Dividends and distributions per Common Share/Unit outstanding $ 2.68750 $ 2.61250 $ 2.47750 (1) The Company’s fourth quarter 2024 dividends and distributions of $ 0.675 per Common Share/Unit outstanding will be included as taxable income in calendar year 2025. (2) The Company’s fourth quarter 2023 dividends and distributions of $ 0.6625 per Common Share/Unit outstanding was included as taxable income in calendar year 2024. (3) The Company’s fourth quarter 2022 dividends and distributions of $ 0.625 per Common Share/Unit outstanding was included as taxable income in calendar year 2023. 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 2024, the Company reported an Alternative Minimum Tax ("AMT") preference adjustment equal to $( 0.04 ) 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 $ 0.06866 per share and $ 0.05462 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. Issuances and retirements of Common Shares and OP Units changes the ownership interests of both the noncontrolling interests and EQR. Such transactions and the related proceeds/payments 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. Issuances and retirements of Common Shares and OP Units changes the ownership interests of both the Limited Partners and EQR. Such transactions and the related proceeds/payments 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 November 2024, the Financial Accounting Standards Board (“FASB”) issued a new standard on disaggregation of income statement expenses, which requires an entity to disclose, on an annual and interim basis, disaggregated information about certain income statement expense line items in a tabular format in the notes to the financial statements. The standard will be effective for annual reporting periods beginning after December 15, 2026 and for interim reporting periods within annual reporting periods beginning after December 15, 2027, with early adoption permitted, and may be applied either prospectively or retrospectively. The Company is currently evaluating the impact of the new rules on its disclosures. In March 2024, the Securities and Exchange Commission ("SEC") adopted final rules that will require certain climate-related information in registration statements and annual reports. In April 2024, the SEC voluntarily stayed the new rules as a result of pending legal challenges. The new rules include a requirement to disclose material climate-related risks, descriptions of board and management oversight and risk management activities, the material impacts of these risks on a registrant’s strategy, business model and outlook, and any material climate-related targets or goals, as well as material effects and costs of severe weather events and other natural conditions and greenhouse gas emissions. Prior to the stay of the new rules, they would have been effective for annual periods beginning January 1, 2025, except for the greenhouse gas emissions disclosures, which would have been effective for annual periods beginning January 1, 2026. The Company is currently evaluating the impact of the new rules on its disclosures. In December 2023, the FASB issued an amendment to the income tax standards which requires disclosure enhancements and further transparency to certain income tax disclosures, most notably the tax rate reconciliation and income taxes paid. The new standard will be effective for annual periods beginning January 1, 2025 and will be applied on a prospective basis with the option to apply the standard retrospectively. Due to the nature of the Company's operations and its status as a REIT, we expect the adoption of the standard to have no impact on its disclosures. See the Income and Other Taxes section above for additional discussion. In November 2023, the FASB issued an amendment to the segment reporting standards which requires disclosure for each reportable segment, on an interim and annual basis, of the significant expense categories and amounts that are regularly provided to the chief operating decision maker and included in each reported measure of a segment’s profit or loss. Additionally, it requires disclosure of the title and position of the individual or the name of the group or committee identified as the chief operating decision maker. The Company adopted the standard as required in this Annual Report on Form 10-K for the year ended December 31, 2024. See Note 16 for further discussion. In August 2020, the 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.
Other	Other The Company is the controlling partner in various consolidated partnerships ow ning 12 properties consisting of 2,656 ap artment units having a noncontrolling interest deficit balance of $ 0.7 million at December 31, 2024 . 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 $ 1.5 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, 2024, the Company estimates the value of Noncontrolling Interest distributions for these two properties would have been approximately $ 51.7 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, 2024 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: 2024 2023 2022 Expected volatility (1) 23.6 % 23.8 % 21.7 % Expected life (2) 5 years 5 years 5 years Expected dividend yield (3) 3.48 % 3.30 % 3.26 % Risk-free interest rate (4) 3.80 % 4.04 % 1.66 % Exercise price per share (5) $ 60.96 $ 66.59 $ 91.59 Option valuation per share $ 11.01 $ 12.67 $ 12.57 (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: 2024 2023 2022 Weighted average fair value per restricted share $ 62.64 $ 61.18 $ 96.84 Weighted average fair value per restricted unit $ 59.70 $ 58.78 $ 93.32
