Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Significant Accounting Policies	1. O rganization 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, 2022, the Parent Company, the Operating Partnership, and their controlled subsidiaries on a consolidated basis owne d 303 properties and held partial interests in an additional 103 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. Risks and Uncertainties The success of the Company's tenants in operating their businesses and their ability to pay rent continue to be significantly influenced by many challenges including the impact of inflation, labor shortages, and supply chain constraints on their cost of doing business. Additionally, macroeconomic and geopolitical risks create challenges that may exacerbate current market conditions in the United States. The policies utilized to address these issues, including raising interest rates, could result in adverse impacts on the U.S. economy, including a slowing of growth or potentially a recession, thereby impacting tenants' businesses and/or decreasing future demand for space in shopping centers. The potential impact of current economic challenges on the Company’s financial condition, results of operations, and cash flows is subject to change and continues to depend on the extent and duration of these risks and uncertainties. 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, 2022, 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 as it relates to exchangeable operating partnership units outstanding and concluded that it has the right to satisfy the redemption requirements of the units by delivering shares of unregistered common stock. Accordingly, the Parent Company classifies EOP units as permanent equity in the accompanying Consolidated Balance Sheets and Consolidated Statements of Equity and Comprehensive Income. The Parent Company serves as general partner of the Operating Partnership. The EOP unit holders have limited rights over the Operating Partnership such that they do not have the power to direct the activities of the Operating Partnership. As such, the Operating Partnership is considered a VIE, and the Parent Company, which consolidates it, is the primary beneficiary. The Parent Company’s only investment is the Operating Partnership. Net income and distributions of the Operating Partnership are allocable to the general and limited common Partnership Units in accordance with their ownership percentages. Real Estate Partnerships As of March 31, 2022, Regency had a partial ownership interest in 113 prop erties through partnerships, of which 10 are consolidated into the Company's financial statements. 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 into its financial statements 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. 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, 2022 December 31, 2021 Assets Net real estate investments $ 216,131 379,075 Cash, cash equivalents and restricted cash 2,868 5,202 Liabilities Notes payable 4,918 5,000 Equity Limited partners’ interests in consolidated partnerships 27,714 27,950 Revenues and Other Receivables Other property income includes parking fees and other 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 are as follows: Three months ended March 31, (in thousands) Timing of satisfaction of performance obligations 2022 2021 Management, transaction and other fees: Property management services Over time $ 3,618 3,771 Asset management services Over time 1,755 1,715 Leasing services Point in time 996 851 Other transaction fees Point in time 315 56 Total management, transaction, and other fees $ 6,684 6,393 The accounts receivable for management services, which are included within Tenant and other receivables in the accompanying Consolidated Balance Sheets, are $ 13.8 million and $ 13.2 million , as of March 31, 2022 and December 31, 2021 , respectively. Recent Accounting Pronouncements The following table provides a brief description of recently adopted accounting pronouncements and impact on our financial statements: Standard Description Date of adoption Effect on the financial statements or other significant matters Recently adopted : ASU 2021-05, Leases (Topic 842): Lessors - Certain Leases with Variable Lease Payments The amendments in this update affect lessor lease classification. Lessors should classify and account for a lease as an operating lease if both of the following criteria are met: (1) have variable lease payments that do not depend on a reference index or a rate and (2) would have resulted in the recognition of a selling loss at lease commencement if classified as sales-type or direct financing. This update results in similar treatment under the current Topic 842 as under the previous Topic 840. January 2022 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 as the Company’s customary lease terms do not result in sales-type or direct financing classification, although future leases may.

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.

Derivative Financial Instrument

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 Maturity Notional Receive Pay March 31, 2022 December 31, 2021 4/7/16 4/1/23 $ 18,932 1 Month LIBOR 1.303 % $ 90 ( 175 ) 12/1/16 11/1/23 31,607 1 Month LIBOR 1.490 % 357 ( 412 ) 9/17/19 3/17/25 24,000 1 Month LIBOR 1.542 % 633 ( 364 ) 6/2/17 6/2/27 35,876 1 Month LIBOR with Floor 2.366 % 162 ( 1,907 ) $ 1,242 ( 2,858 ) (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 . 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, 2022, 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 Income (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) 2022 2021 2022 2021 2022 2021 Interest rate swaps $ 8,968 5,810 Interest expense $ 1,010 1,035 Interest expense, net $ 36,738 36,936 As of March 31, 2022, the Company expects approximately $ 456,000 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 (“Recoverable Costs”). 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 the tenants’ contractual obligations to reimburse the Company for their portion of 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, 2022 2021 Operating lease income Fixed and in-substance fixed lease income $ 207,502 196,054 Variable lease income 72,026 64,067 Other lease related income, net: Above/below market rent and tenant rent inducement amortization, net 5,689 5,996 Uncollectible straight-line rent 2,282 ( 2,035 ) Uncollectible amounts billable in lease income 6,146 2,275 Total lease income $ 293,645 266,357 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 in which collectibility is considered probable. At lease commencement, the Company generally expects that collectibility of substantially all payments due under the lease is probable due to the Company’s credit checks on tenants and other credit 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 no longer to be probable of collection. Should collectibility of Lease income become probable again, through evaluation of qualitative and quantitative measures on a tenant by tenant basis, accrual basis accounting resumes and all commencement-to-date straight-line rent is recognized in that period. In addition to the lease-specific collectibility assessment performed under Topic 842, the Company may also recognize 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. The following table represents the components of Tenant and other receivables in the accompanying Consolidated Balance Sheets: (in thousands) March 31, 2022 December 31, 2021 Tenant receivables $ 17,756 $ 27,354 Straight-line rent receivables 109,953 103,942 Other receivables (1) 24,143 21,795 Total tenant and other receivables $ 151,852 $ 153,091 (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, 2022 December 31, 2021 (in thousands) Carrying Fair Value Carrying Fair Value Financial liabilities: Notes payable $ 3,716,717 3,782,877 3,718,944 4,103,533 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, 2022, and December 31, 2021 , 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 loss (income) in the accompanying Consolidated Statements of Operations, and include unrealized losses of $ 3.0 million and unrealized gains of $ 417,462 during the three months ended March 31, 2022 and 2021, 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, 2022 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 $ 46,358 46,358 — — Available-for-sale debt securities 14,974 — 14,974 — Interest rate derivatives 1,242 — 1,242 — Total $ 62,574 46,358 16,216 — Fair Value Measurements as of December 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 $ 49,513 49,513 — — Available-for-sale debt securities 15,599 — 15,599 — Interest rate derivatives — — - — Total $ 65,112 49,513 15,599 — Liabilities: Interest rate derivatives $ ( 2,858 ) — ( 2,858 ) — The following table presents the placement in the fair value hierarchy of assets and liabilities that are measured at fair value on a nonrecurring basis: Fair Value Measurements as of December 31, 2021 Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs Total Gains (in thousands) Balance (Level 1) (Level 2) (Level 3) (Losses) Operating properties $ 140,500 — — 140,500 ( 84,277 ) During the year ended December 31, 2021 , the Company revalued two shopping centers to estimated fair value due to a change in expected hold period using a discounted cash flow model with a discount rate of 7.2 % and a terminal capitalization rate of 5.25 %.

Under the current authorization, the program is set to expire on February 3, 2023 , but may be modified or terminated at any time at the discretion of the Board. The timing and actual number of shares purchased under the program depend upon marketplace conditions, liquidity needs, and other factors.

Commitments and Contingencies	12. Commitments and Contingencies Litigation The Company is involved in litigation on a number of matters, and is subject to other disputes that arise in the ordinary course of business. While the outcome of any particular lawsuit or dispute cannot be predicted with certainty, in the opinion of management, the Company's currently pending litigation and disputes are not expected to have a material adverse effect on the Company's consolidated financial position, results of operations, or liquidity. 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, older underground petroleum storage tanks and other historic land use. 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, 2022 and December 31, 2021, the Company had $ 9.4 million in letters of credit outstanding.

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, 2022, 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 as it relates to exchangeable operating partnership units outstanding and concluded that it has the right to satisfy the redemption requirements of the units by delivering shares of unregistered common stock. Accordingly, the Parent Company classifies EOP units as permanent equity in the accompanying Consolidated Balance Sheets and Consolidated Statements of Equity and Comprehensive Income. The Parent Company serves as general partner of the Operating Partnership. The EOP unit holders have limited rights over the Operating Partnership such that they do not have the power to direct the activities of the Operating Partnership. As such, the Operating Partnership is considered a VIE, and the Parent Company, which consolidates it, is the primary beneficiary. The Parent Company’s only investment is the Operating Partnership. Net income and distributions of the Operating Partnership are allocable to the general and limited common Partnership Units in accordance with their ownership percentages.
Risks and Uncertainties	Risks and Uncertainties The success of the Company's tenants in operating their businesses and their ability to pay rent continue to be significantly influenced by many challenges including the impact of inflation, labor shortages, and supply chain constraints on their cost of doing business. Additionally, macroeconomic and geopolitical risks create challenges that may exacerbate current market conditions in the United States. The policies utilized to address these issues, including raising interest rates, could result in adverse impacts on the U.S. economy, including a slowing of growth or potentially a recession, thereby impacting tenants' businesses and/or decreasing future demand for space in shopping centers. The potential impact of current economic challenges on the Company’s financial condition, results of operations, and cash flows is subject to change and continues to depend on the extent and duration of these risks and uncertainties.
Real Estate Partnerships	Real Estate Partnerships As of March 31, 2022, Regency had a partial ownership interest in 113 prop erties through partnerships, of which 10 are consolidated into the Company's financial statements. 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 into its financial statements 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. 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, 2022 December 31, 2021 Assets Net real estate investments $ 216,131 379,075 Cash, cash equivalents and restricted cash 2,868 5,202 Liabilities Notes payable 4,918 5,000 Equity Limited partners’ interests in consolidated partnerships 27,714 27,950
Revenues and Other Receivables	Revenues and Other Receivables Other property income includes parking fees and other 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 are as follows: Three months ended March 31, (in thousands) Timing of satisfaction of performance obligations 2022 2021 Management, transaction and other fees: Property management services Over time $ 3,618 3,771 Asset management services Over time 1,755 1,715 Leasing services Point in time 996 851 Other transaction fees Point in time 315 56 Total management, transaction, and other fees $ 6,684 6,393 The accounts receivable for management services, which are included within Tenant and other receivables in the accompanying Consolidated Balance Sheets, are $ 13.8 million and $ 13.2 million , as of March 31, 2022 and December 31, 2021 , respectively.

Lessors should classify and account for a lease as an operating lease if both of the following criteria are met: (1) have variable lease payments that do not depend on a reference index or a rate and (2) would have resulted in the recognition of a selling loss at lease commencement if classified as sales-type or direct financing. This update results in similar treatment under the current Topic 842 as under the previous Topic 840. January 2022 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 as the Company’s customary lease terms do not result in sales-type or direct financing classification, although future leases may.
