Organization Consolidation And Presentation Of Financial Statements [Abstract]
Organization and Significant Accounting Policies	1. Organization and Significant Accounting Policies General Regency Centers Corporation (the “Parent Company”) began its operations as a Real Estate Investment Trust (“REIT”) in 1993 and is the general partner of Regency Centers, L.P. (the “Operating Partnership”). The Parent Company primarily engages in the ownership, management, leasing, acquisition, and development and redevelopment of shopping centers through the Operating Partnership, and has no other assets other than through its investment in the Operating Partnership, and its only liabilities are $200 million of unsecured private placement notes, which are co-issued and guaranteed by the Operating Partnership. The Parent Company guarantees all of the unsecured debt of the Operating Partnership. As of March 31, 2021, the Parent Company, the Operating Partnership, and their controlled subsidiaries on a consolidated basis owned 293 properties and held partial interests in an additional 113 properties through unconsolidated Investments in real estate partnerships (also referred to as “joint ventures” or “investment partnerships”). The consolidated financial statements reflect all adjustments which are, in the opinion of management, necessary to fairly state the results for the interim periods presented. These adjustments are considered to be of a normal recurring nature. COVID-19 Update The COVID-19 pandemic continues to create volatility and uncertainty in the Company’s business performance with particular impact to cash collections, tenant move outs, and new and renewal leasing volumes. The speed of the continued vaccine deployment and the timing of states and localities lifting mandated closures or capacity restrictions, has and will continue to influence the success of tenants. The Company actively monitors its cash collections amid the continuing pandemic. Collection experience since the pandemic began has been lower than historical pre-pandemic averages, but has increased since its low point in the second quarter of 2020 as businesses reopened in states that have lifted or reduced capacity restrictions. Collection rates are expected to remain lower than historical pre-pandemic averages for the foreseeable future until restrictions are significantly lifted and consumers return to in-store experiences. Although continuing to improve, tenants at centers in downtown business districts heavily reliant on employees returning to in-office work are trailing in recovery. Please also refer to the Company’s Annual Report on Form 10-K for the year ended December 31, 2020 for additional discussion of the impact of the COVID-19 pandemic on the Company’s business including, without limitation, the Risk Factors discussed in Item 1A of Part I thereof. Consolidation The Company consolidates properties that are wholly-owned and properties where it owns less than 100%, but which it has control over the activities most important to the overall success of the partnership. Control is determined using an evaluation based on accounting standards related to the consolidation of Variable Interest Entities ("VIEs") and voting interest entities. Ownership of the Operating Partnership The Operating Partnership’s capital includes general and limited common Partnership Units. As of March 31, 2021, the Parent Company owned approximately 99.6% of the outstanding common Partnership Units of the Operating Partnership, with the remaining limited common Partnership Units held by third parties (“Exchangeable operating partnership units” or “EOP units”). Each EOP unit is exchangeable for cash or one share of common stock of the Parent Company, at the discretion of the Parent Company, and the unit holder cannot require redemption in cash or other assets. The Parent Company has evaluated the conditions as specified under Accounting Standards Codification (“ASC”) Topic 480, Distinguishing Liabilities from Equity Real Estate Partnerships As of March 31, 2021, Regency had a partial ownership interest in 123 properties through partnerships, of which 10 are consolidated. Regency's partners include institutional investors and other real estate developers and/or operators (the “Partners” or “limited partners”). Regency has a variable interest in these entities through its equity interests, with Regency the primary beneficiary in certain of these real estate partnerships. As such, Regency consolidates the partnerships for which it is the primary beneficiary and reports the limited partners’ interests as Noncontrolling interests. For those partnerships which Regency is not the primary beneficiary and does not control, but has significant influence, Regency recognizes its investment in them using the equity method of accounting. The assets of these partnerships are restricted to the use of the partnerships and cannot be used by general creditors of the Company. And similarly, the obligations of the partnerships can only be settled by the assets of these partnerships or additional contributions by the partners. The major classes of assets, liabilities, and non-controlling equity interests held by the Company's consolidated VIEs, exclusive of the Operating Partnership, are as follows: (in thousands) March 31, 2021 December 31, 2020 Assets Net real estate investments $ 127,513 127,240 Cash, cash equivalents and restricted cash 4,793 4,496 Liabilities Notes payable 6,349 6,340 Equity Limited partners’ interests in consolidated partnerships 28,534 28,685 Revenues and Other Receivables Other property income includes incidental income from the properties and is generally recognized at the point in time that the performance obligation is met. All income from contracts with the Company's real estate partnerships is included within Management, transaction and other fees on the Consolidated Statements of Operations. The primary components of these revenue streams, the timing of satisfying the performance obligations, and amounts recognized are as follows: Three months ended March 31, (in thousands) Timing of satisfaction of performance obligations 2021 2020 Management, transaction and other fees: Property management services Over time 3,771 3,879 Asset management services Over time 1,715 1,838 Leasing services Point in time 851 710 Other transaction fees Point in time 56 389 Total management, transaction, and other fees $ 6,393 6,816 The accounts receivable for management services, which are included within Tenant and other receivables in the accompanying Consolidated Balance Sheets, are $10.5 million and $9.9 million, as of March 31, 2021 and December 31, 2020, respectively. Recent Accounting Pronouncements The following table provides a brief description of recent accounting pronouncements and expected impact on our financial statements: Standard Description Date of adoption Effect on the financial statements or other significant matters Recently adopted: ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes The amendments in this update simplify the accounting for income taxes by removing certain exceptions to the general principles in Topic 740, Income Taxes Notable changes and clarifications of potential impact include income-based franchise taxes being considered income tax, of which the Company has none, and interim period recognition of enacted changes in tax laws or rates, which is consistent with the Company’s existing practice. January 2021 The adoption of this standard did not have a material impact to the Company’s financial condition, results of operations, cash flows or related footnote disclosures.

A decision to sell a reporting unit results in the need to evaluate its goodwill for recoverability and may result in impairment. Additionally, other changes impacting a reporting unit may be considered a triggering event. If events occur that trigger an impairment evaluation at multiple reporting units, a goodwill impairment may be significant. During 2020, the Company recognized $132.2 million of Goodwill impairment following the market disruptions of the COVID-19 pandemic, which was considered a triggering event requiring evaluation of reporting unit fair values for Goodwill impairment. Of the 269 reporting units with Goodwill, 87 were determined to have fair values lower than carrying value, resulting in $132.2 million of Goodwill impairment.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	6. Derivative Financial Instruments The Company may use derivative financial instruments, including interest rate swaps, caps, options, floors, and other interest rate derivative contracts, to hedge all or a portion of the interest rate risk associated with its borrowings. The principal objective of such arrangements is to minimize the risks and/or costs associated with the Company’s operating and financial structure as well as to hedge specific anticipated transactions. The Company does not intend to utilize derivatives for speculative transactions or purposes other than interest rate risk management. The use of derivative financial instruments carries certain risks, including the risk that the counterparties to these contractual arrangements are not able to perform under the agreements. To mitigate this risk, the Company only enters into derivative financial instruments with counterparties with high credit ratings and with major financial institutions with which the Company and its affiliates may also have other financial relationships. The Company does not anticipate that any of the counterparties will fail to meet their obligations. The Company’s objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company primarily uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. The following table summarizes the terms and fair values of the Company's derivative financial instruments, as well as their classification on the Consolidated Balance Sheets: Fair Value (in thousands) Assets (Liabilities) (1) Effective Date Maturity Date Notional Amount Receive Variable Rate of Pay Fixed Rate of March 31, 2021 December 31, 2020 8/1/16 1/5/22 (2) $ 265,000 1 Month LIBOR with Floor 1.053% $ — (2,472 ) 4/7/16 4/1/23 19,312 1 Month LIBOR 1.303% (413 ) (494 ) 12/1/16 11/1/23 32,220 1 Month LIBOR 1.490% (955 ) (1,181 ) 9/17/19 3/17/25 24,000 1 Month LIBOR 1.542% (834 ) (1,288 ) 6/2/17 6/2/27 36,449 1 Month LIBOR with Floor 2.366% (2,414 ) (3,856 ) $ (4,616 ) (9,291 ) (1) Derivatives in an asset position are included within Other assets in the accompanying Consolidated Balance Sheets, while those in a liability position are included within Accounts payable and other liabilities. (2 ) In January 2021, the Company These derivative financial instruments are all interest rate swaps, which are designated and qualify as cash flow hedges. The Company does not use derivatives for trading or speculative purposes and, as of March 31, 2021, does not have any derivatives that are not designated as hedges. The changes in the fair value of derivatives designated and qualifying as cash flow hedges is recorded in Accumulated Other Comprehensive Loss (“AOCI”) and subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. The following table represents the effect of the derivative financial instruments on the accompanying consolidated financial statements: Location and Amount of Gain (Loss) Recognized in OCI on Derivative Location and Amount of Gain (Loss) Reclassified from AOCI into Income Total amounts presented in the Consolidated Statements of Operations in which the effects of cash flow hedges are recorded Three months ended March 31, Three months ended March 31, Three months ended March 31, (in thousands) 2021 2020 2021 2020 2021 2020 Interest rate swaps $ 5,810 (16,079 ) Interest expense $ 1,035 1,425 Interest expense, net $ 36,936 37,436 As of March 31, 2021, the Company expects approximately $3.7 million of accumulated comprehensive losses on derivative instruments in AOCI, including the Company's share from its Investments in real estate partnerships, to be reclassified into earnings during the next 12 months.

Leases

Leases [Abstract]
Leases	7. Leases All of the Company’s leases are classified as operating leases. The Company's Lease income is comprised of both fixed and variable income. Fixed and in-substance fixed lease income includes stated amounts per the lease contract, which are primarily related to base rent, and in some cases stated amounts for common area maintenance (“CAM”), real estate taxes, and insurance. Income for these amounts is recognized on a straight-line basis. Variable lease income includes the following two main items in the lease contracts: (i) Recoveries from tenants represents amounts tenants are contractually obligated to reimburse the Company for the tenants’ portion of actual Recoverable Costs incurred. Generally the Company’s leases provide for the tenants to reimburse the Company based on the tenants’ share of the actual costs incurred in proportion to the tenants’ share of leased space in the property. (ii) Percentage rent represents amounts billable to tenants based on the tenants' actual sales volume in excess of levels specified in the lease contract. The following table provides a disaggregation of lease income recognized as either fixed or variable lease income based on the criteria specified in ASC Topic 842: (in thousands) Three months ended March 31, 2021 2020 Operating lease income Fixed and in-substance fixed lease income $ 196,054 204,943 Variable lease income 64,067 64,668 Other lease related income, net: Above/below market rent and tenant rent inducement amortization, net 5,996 12,880 Uncollectible straight line rent (2,035 ) (3,902 ) Uncollectible amounts billable in lease income 2,275 (4,052 ) Total lease income $ 266,357 274,537 Lease income for operating leases with fixed payment terms is recognized on a straight-line basis over the expected term of the lease for all leases for which collectibility is considered probable at the commencement date. At lease commencement, the Company generally expects that collectibility is probable due to the Company’s credit checks on tenants and other creditworthiness analysis undertaken before entering into a new lease; therefore, income from most operating leases is initially recognized on a straight-line basis. For operating leases in which collectibility of Lease income is not considered probable, Lease income is recognized on a cash basis and all previously recognized straight-line rent receivables are reversed in the period in which the Lease income is determined not to be probable of collection. In additio n to the lease-specific collecti bility assessment performed under Topic 842, the Company also recognizes a general reserve, as a reduction to Lease income, for its portfolio of operating lease receivables which are not expected to be fully collectible based on the Company’s historical collection experience. COVID-19 Pandemic and Rent Concessions During 2020, in response to the pandemic and the resulting entry into agreements for rent concessions between tenants and landlords, the FASB issued interpretive guidance relating to the accounting for lease concessions provided as a result of COVID-19. In this guidance, entities could elect not to apply lease modification accounting with respect to such lease concessions, and instead, treat the concession as if it was a part of the existing contract and therefore continue to recognize the deferred rents in the period originally billed subject to separate collectibility assessments under Topic 842. This guidance is only applicable to COVID-19 related lease concessions that do not result in a substantial increase in the right of the lessor or the obligations of the lessee. The Company has elected to treat concessions that satisfy this criteria as though the concession was part of the existing contract and therefore not treated like a lease modification. During the three months ended March 31, 2021, the Company experienced higher uncollectible lease income on current period billings compared to the three months ended March 31, 2020 when the Company was only seeing the first indications of the pandemic’s impact on tenants. However, this higher uncollectible lease income was offset by collections of prior period billings from our cash basis tenants resulting in a net positive impact of $2.3 million. The Company continues to negotiate with certain remaining tenants, which may result in further rent concessions as determined necessary and appropriate. Collectibility of these concessions generally includes consideration of the tenants’ business performance, ability to sustain their business in the current environment, as well as an assessment of their credit worthiness and ability to repay such amounts in the future. The following table represents the components of Tenant and other receivables in the accompanying Consolidated Balance Sheets: (in thousands) March 31, 2021 December 31, 2020 Tenant receivables $ 21,630 $ 39,658 Straight-line rent receivables 87,180 86,615 Other receivables (1) 18,645 17,360 Total tenant and other receivables $ 127,455 $ 143,633 (1) Other receivables include construction receivables, insurance receivables, and amounts due from real estate partnerships for Management, transaction and other fee income.

Fair Value Disclosures [Abstract]
Fair Value Measurements	8. Fair Value Measurements (a) Disclosure of Fair Value of Financial Instruments All financial instruments of the Company are reflected in the accompanying Consolidated Balance Sheets at amounts which, in management's estimation, reasonably approximate their fair values, except for the following: March 31, 2021 December 31, 2020 (in thousands) Carrying Amount Fair Value Carrying Amount Fair Value Financial liabilities: Notes payable $ 3,652,242 3,943,126 3,658,405 4,102,382 Unsecured credit facilities $ — — 264,679 265,226 The above fair values represent management's estimate of the amounts that would be received from selling those assets or that would be paid to transfer those liabilities in an orderly transaction between market participants as of March 31, 2021 and December 31, 2020, respectively. These fair value measurements maximize the use of observable inputs which are classified within level 2 of the fair value hierarchy. However, in situations where there is little, if any, market activity for the asset or liability at the measurement date, the fair value measurement reflects the Company's own judgments about the assumptions that market participants would use in pricing the asset or liability. The Company develops its judgments based on the best information available at the measurement date, including expected cash flows, appropriate risk-adjusted discount rates, and available observable and unobservable inputs. Service providers involved in fair value measurements are evaluated for competency and qualifications on an ongoing basis. As considerable judgment is often necessary to estimate the fair value of these financial instruments, the fair values presented above are not necessarily indicative of amounts that will be realized upon disposition of the financial instruments. (b) Fair Value Measurements The following financial instruments are measured at fair value on a recurring basis: Securities The Company has investments in marketable securities that are included within Other assets on the accompanying Consolidated Balance Sheets. The fair value of the securities was determined using quoted prices in active markets, which are considered Level 1 inputs of the fair value hierarchy. Changes in the value of securities are recorded within Net investment (income) loss in the accompanying Consolidated Statements of Operations, and include unrealized gains of $0.4 million and unrealized losses of $5.4 million during the three months ended March 31, 2021 and 2020, respectively. Available-for-Sale Debt Securities Available-for-sale debt securities consist of investments in certificates of deposit and corporate bonds, and are recorded at fair value using matrix pricing methods to estimate fair value, which are considered Level 2 inputs of the fair value hierarchy. Unrealized gains or losses on these debt securities are recognized through other comprehensive income. Interest Rate Derivatives The fair value of the Company's interest rate derivatives is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. The Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty's nonperformance risk in the fair value measurements. Although the Company has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads, to evaluate the likelihood of default by the Company and its counterparties. The Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuation of its interest rate swaps. As a result, the Company determined that its interest rate swaps valuation in its entirety is classified in Level 2 of the fair value hierarchy. The following tables present the placement in the fair value hierarchy of assets and liabilities that are measured at fair value on a recurring basis: Fair Value Measurements as of March 31, 2021 Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs (in thousands) Balance (Level 1) (Level 2) (Level 3) Assets: Securities $ 45,337 45,337 — — Available-for-sale debt securities 15,656 — 15,656 — Total $ 60,993 45,337 15,656 — Liabilities: Interest rate derivatives $ (4,616 ) — (4,616 ) — Fair Value Measurements as of December 31, 2020 Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs (in thousands) Balance (Level 1) (Level 2) (Level 3) Assets: Securities $ 44,986 44,986 — — Available-for-sale debt securities 15,706 — 15,706 — Total $ 60,692 44,986 15,706 — Liabilities: Interest rate derivatives $ (9,291 ) — (9,291 ) — There were no assets measured at fair value on a nonrecurring basis as of March 31, 2021.

Commitments and Contingencies	13. Commitments and Contingencies Litigation The Company is involved in litigation on a number of matters and is subject to certain claims, which arise in the normal course of business, none of which, in the opinion of management, is expected to have a material adverse effect on the Company's consolidated financial position, results of operations, or liquidity. However, no assurances can be given as to the outcome of any threatened or pending legal proceedings. Legal fees are expensed as incurred. Environmental The Company is subject to numerous environmental laws and regulations pertaining primarily to chemicals historically used by certain current and former dry cleaning tenants, the existence of asbestos in older shopping centers, and older underground petroleum storage tanks. The Company believes that the ultimate disposition of currently known environmental matters will not have a material effect on its financial position, liquidity, or operations. The Company can give no assurance that existing environmental studies with respect to its shopping centers have revealed all potential environmental contaminants; that its estimate of liabilities will not change as more information becomes available; that any previous owner, occupant or tenant did not create any material environmental condition not known to the Company; that the current environmental condition of the shopping centers will not be affected by tenants and occupants, by the condition of nearby properties, or by unrelated third parties; and that changes in applicable environmental laws and regulations or their interpretation will not result in additional environmental liability to the Company. Letters of Credit The Company has the right to issue letters of credit under the Line up to an amount not to exceed $50.0 million, which reduces the credit availability under the Line. These letters of credit are primarily issued as collateral on behalf of its captive insurance program and to facilitate the construction of development projects. As of March 31, 2021 and December 31, 2020, the Company had $9.7 million

Organization Consolidation And Presentation Of Financial Statements [Abstract]
Consolidation	Consolidation The Company consolidates properties that are wholly-owned and properties where it owns less than 100%, but which it has control over the activities most important to the overall success of the partnership. Control is determined using an evaluation based on accounting standards related to the consolidation of Variable Interest Entities ("VIEs") and voting interest entities. Ownership of the Operating Partnership The Operating Partnership’s capital includes general and limited common Partnership Units. As of March 31, 2021, the Parent Company owned approximately 99.6% of the outstanding common Partnership Units of the Operating Partnership, with the remaining limited common Partnership Units held by third parties (“Exchangeable operating partnership units” or “EOP units”). Each EOP unit is exchangeable for cash or one share of common stock of the Parent Company, at the discretion of the Parent Company, and the unit holder cannot require redemption in cash or other assets. The Parent Company has evaluated the conditions as specified under Accounting Standards Codification (“ASC”) Topic 480, Distinguishing Liabilities from Equity
Real Estate Partnerships	Real Estate Partnerships As of March 31, 2021, Regency had a partial ownership interest in 123 properties through partnerships, of which 10 are consolidated. Regency's partners include institutional investors and other real estate developers and/or operators (the “Partners” or “limited partners”). Regency has a variable interest in these entities through its equity interests, with Regency the primary beneficiary in certain of these real estate partnerships. As such, Regency consolidates the partnerships for which it is the primary beneficiary and reports the limited partners’ interests as Noncontrolling interests. For those partnerships which Regency is not the primary beneficiary and does not control, but has significant influence, Regency recognizes its investment in them using the equity method of accounting. The assets of these partnerships are restricted to the use of the partnerships and cannot be used by general creditors of the Company. And similarly, the obligations of the partnerships can only be settled by the assets of these partnerships or additional contributions by the partners. The major classes of assets, liabilities, and non-controlling equity interests held by the Company's consolidated VIEs, exclusive of the Operating Partnership, are as follows: (in thousands) March 31, 2021 December 31, 2020 Assets Net real estate investments $ 127,513 127,240 Cash, cash equivalents and restricted cash 4,793 4,496 Liabilities Notes payable 6,349 6,340 Equity Limited partners’ interests in consolidated partnerships 28,534 28,685
