The Parent Company engages in the ownership, management, leasing, acquisition, and development of retail shopping centers through the Operating Partnership, and has no other assets or liabilities other than through its investment in the Operating Partnership. The Parent Company currently owns approximately 99.9% of the outstanding common Partnership Units of the Operating Partnership. As of September 30, 2016 , the Parent Company, the Operating Partnership, and their controlled subsidiaries on a consolidated basis (the "Company” or “Regency”) owned 197 retail shopping centers and held partial interests in an additional 110 retail shopping centers 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 a fair statement of the results for the interim periods presented. These adjustments are considered to be of a normal recurring nature. Consolidation The Company consolidates properties that are wholly owned or properties where it owns less than 100%, but which it controls. Control is determined using an evaluation based on accounting standards related to the consolidation of voting interest entities and variable interest entities ("VIEs"). For joint ventures that are determined to be a VIE, the Company consolidates the entity where it is deemed to be the primary beneficiary. Determination of the primary beneficiary is based on whether an entity has (1) the power to direct the activities of the VIE that most significantly impact the entity's economic performance, and (2) the obligation to absorb losses of the entity that could potentially be significant to the VIE or the right to receive benefits from the entity that could potentially be significant to the VIE. The Company's determination of the primary beneficiary considers all relationships between it and the VIE, including management agreements and other contractual arrangements. Ownership of the Operating Partnership The Operating Partnership’s capital includes general and limited common Partnership Units. As of September 30, 2016 , the Parent Company owned approximately 99.9% of the outstanding common Partnership Units of the Operating Partnership with the remaining limited Partnership Units held by third parties (“Exchangeable operating partnership units” or “EOP units”). 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 characteristics of a controlling financial interest. As such, the Operating Partnership is considered a variable interest entity, and the Parent Company is the primary beneficiary which consolidates it. The Parent Company’s only investment is the Operating Partnership. Real Estate Partnerships Regency has an ownership interest in 121 properties through partnerships, of which 11 are consolidated, with institutional investors, other real estate developers and/or operators, and individual parties who help Regency source transactions for development and investment ("the Partners", "limited partners"). Regency has a variable interest in these entities through its equity interests. As managing member, Regency maintains the books and records and typically provides leasing and property management to the partnerships. The partners’ level of involvement varies from protective decisions (debt, bankruptcy, selling primary asset(s) of business) to involvement in approving leases, operating budgets, and capital budgets. • Those partnerships for which the partners only have protective rights are considered VIEs under ASC 810, Consolidation. Regency is the primary beneficiary of these VIEs as Regency has power over these partnerships and they operate primarily for the benefit of Regency. As such, Regency consolidates these entities and reports the limited partners’ interest as noncontrolling interests. The majority of the operations of the VIEs are funded with cash flows generated by the properties, or in the case of developments, with capital contributions or third party construction loans. Regency does not provide financial support to the VIEs. • Those partnerships for which the partners are involved in the day to day decisions and do not have any other aspects that would cause them to be considered VIEs, are evaluated for consolidation using the voting interest model. ◦ Those partnerships in which Regency has a controlling financial interest are consolidated and the limited partners’ ownership interest and share of net income is recorded as noncontrolling interest. ◦ Those partnerships in which Regency does not have a controlling financial interest are accounted for using the equity method and its ownership interest is recognized through single-line presentation as Investments in Real Estate Partnerships, in the Consolidated Balance Sheet, and Equity in Income of Investments in Real Estate Partnerships, in the Consolidated Statements of Operations. Distributions received from these partnerships are accounted for using the look-through method with returns of capital from property sales or debt financing considered investing cash flows and the remaining distributions generally considered operating cash flows. 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 these partnerships can only be settled by the assets of these partnerships. The major classes of assets, liabilities, and non-controlling equity interests held by the Company's VIEs are as follows: (in thousands) September 30, 2016 December 31, 2015 Assets Real estate assets, net $ 84,586 81,424 Cash and cash equivalents 7,822 790 Liabilities Notes payable 8,169 17,948 Equity Limited partners’ interests in consolidated partnerships 17,374 11,058 Reclassifications During the nine months ended September 30, 2016 , the Company reclassified its land held for future development from Properties in development to Land within the accompanying Consolidated Balance Sheets. The Company reclassified prior period amounts of $47.3 million to conform to current period presentation.

The Company has the option to terminate and settle at any date prior to this. (2) 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. (3) In 2014, the Company entered into $220 million of forward starting interest rate swaps to hedge the interest rate on new fixed rate ten year debt that the Company expected to issue in June 2017 for the specific purpose of repaying at maturity the $300 million notes. These interest rate swaps locked in a weighted average fixed rate of 3.48% , before the Company's credit spread. These swaps were settled during the during the third quarter of 2016, as further described below. 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 September 30, 2016 , does not have any derivatives that are not designated as hedges. The Company has master netting agreements; however, the Company does not have multiple derivatives subject to a single master netting agreement with the same counterparties. Therefore, none are offset in the accompanying Consolidated Balance Sheets. The effective portion of 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 ineffective portion of the change in fair value of the derivatives is recognized directly in earnings within Interest expense, in the accompanying Consolidated Statements of Operations. The following table represents the effect of the derivative financial instruments on the accompanying consolidated financial statements: Derivatives in FASB Amount of Gain (Loss) Location and Amount of Gain Location and Amount of Gain or Three months ended September 30, Three months ended September 30, Three months ended September 30, (in thousands) 2016 2015 2016 2015 2016 2015 Interest rate swaps $ 1,294 (15,768 ) Interest $ (2,525 ) (2,155 ) Loss on derivative instruments $ (40,586 ) — Derivatives in FASB Amount of Gain (Loss) Location and Amount of Gain Location and Amount of Gain or Nine months ended September 30, Nine months ended September 30, Nine months ended September 30, (in thousands) 2016 2015 2016 2015 2016 2015 Interest rate swaps $ (25,338 ) (11,274 ) Interest $ (7,477 ) (6,654 ) Loss on derivative instruments $ (40,586 ) — As of September 30, 2016 , the Company expects $10.7 million of net deferred losses on derivative instruments accumulated in Other comprehensive income, including the Company's share from its Investments in real estate partnerships, to be reclassified into earnings during the next 12 months. Included in the reclass is $8.4 million which is related to previously settled swaps on the Company's ten year fixed rate unsecured loans. Hedge Settlement During the third quarter of 2016, the Company initiated and completed a $400.1 million equity offering, as further described in note 7, for the primary purpose of funding the early redemption of its $300 million notes. The Company also used $40.6 million from the net offering proceeds to settle $220 million of forward starting swaps related to new debt previously expected to be issued in 2017 to repay the notes at maturity. As a result of the equity offering, the Company believed that the issuance of new fixed rate debt within the remaining period of the forward starting swaps was probable not to occur. Accordingly, the Company ceased hedge accounting and reclassified the $40.6 million paid to settle the forward starting swaps from Accumulated other comprehensive loss to earnings during the third quarter of 2016.

Fair Value Disclosures [Abstract]
Fair Value Measurements	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: September 30, 2016 December 31, 2015 (in thousands) Carrying Amount Fair Value Carrying Amount Fair Value Financial assets: Notes receivable $ 10,480 10,460 $ 10,480 10,620 Financial liabilities: Notes payable $ 1,364,200 1,478,100 $ 1,699,771 1,793,200 Unsecured credit facilities $ 263,421 264,800 $ 164,514 165,300 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 September 30, 2016 and December 31, 2015 . These fair value measurements maximize the use of observable inputs. 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, appropriately 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. The following methods and assumptions were used to estimate the fair value of these financial instruments: Notes Receivable The fair value of the Company's Notes receivable is estimated by calculating the present value of future contractual cash flows discounted at interest rates available for notes of the same terms and maturities, adjusted for counter-party specific credit risk. The fair value of Notes receivable was determined primarily using Level 3 inputs of the fair value hierarchy, which considered counter-party credit risk and collateral risk of the underlying property securing the note receivable. Notes Payable The fair value of the Company's unsecured debt is estimated based on the quoted market prices for the same or similar issues or on the current rates offered to the Company for debt of the same remaining maturities. The fair value of the unsecured debt was determined using Level 2 inputs of the fair value hierarchy. The fair value of the Company's mortgage notes payable is estimated by discounting future cash flows of each instrument at rates that reflect the current market rates available to the Company for debt of the same terms and maturities. Fixed rate loans assumed in connection with real estate acquisitions are recorded in the accompanying consolidated financial statements at fair value at the time the property is acquired. The fair value of the mortgage notes payable was determined using Level 2 inputs of the fair value hierarchy. Unsecured Credit Facilities The fair value of the Company's Unsecured credit facilities is estimated based on the interest rates currently offered to the Company by financial institutions. The fair value of the credit facilities was determined using Level 2 inputs of the fair value hierarchy. The following interest rate ranges were used by the Company to estimate the fair value of its financial instruments: September 30, 2016 December 31, 2015 Low High Low High Notes receivable 6.8% 6.8% 6.3% 6.3% Notes payable 2.7% 3.8% 2.8% 4.2% Unsecured credit facilities 1.5% 1.5% 1.1% 1.1% (b) Fair Value Measurements The following financial instruments are measured at fair value on a recurring basis: Trading Securities Held in Trust The Company has investments in marketable securities, which are assets of the non-qualified deferred compensation plan ("NQDCP"), that are classified as trading securities held in trust on the accompanying Consolidated Balance Sheets. The fair value of the Trading securities held in trust was determined using quoted prices in active markets, which are considered Level 1 inputs of the fair value hierarchy. Changes in the value of trading securities are recorded within net investment (income) loss from deferred compensation plan in the accompanying Consolidated Statements of Operations. Available-for-Sale Securities Available-for-sale 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 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 September 30, 2016 (in thousands) Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs Assets: Balance (Level 1) (Level 2) (Level 3) Trading securities held in trust $ 29,280 29,280 — — Available-for-sale securities 8,017 — 8,017 — Interest rate derivatives 476 — 476 — Total $ 37,773 29,280 8,493 — Liabilities: Interest rate derivatives $ (1,637 ) — (1,637 ) — Fair Value Measurements as of December 31, 2015 (in thousands) Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs Assets: Balance (Level 1) (Level 2) (Level 3) Trading securities held in trust $ 29,093 29,093 — — Available-for-sale securities 7,922 — 7,922 — Total $ 37,015 29,093 7,922 — Liabilities: Interest rate derivatives $ (20,539 ) — (20,539 ) — There were no assets measured at fair value on a nonrecurring basis as of September 30, 2016 or December 31, 2015 .

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies 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. Legal fees are expensed as incurred. The Company is also subject to numerous environmental laws and regulations as they apply to real estate pertaining to chemicals used by the dry cleaning industry, the existence of asbestos in older shopping centers, and 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 the shopping centers have revealed all potential environmental liabilities, that any previous owner, occupant or tenant did not create any material environmental condition not known to it, 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, or that changes in applicable environmental laws and regulations or their interpretation will not result in additional environmental liability to the Company. 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 September 30, 2016 and December 31, 2015 , the Company had $5.8 million and $5.9 million , respectively, in letters of credit outstanding.

New Accounting Pronouncements and Changes in Accounting Principles [Text Block]	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 2015-02, February 2015 , Consolidation (Topic 810): Amendments to the Consolidation Analysis ASU 2015-02 affects reporting entities that are required to evaluate whether they should consolidate certain legal entities. ASU 2015-02 modifies the evaluation of whether limited partnerships and similar legal entities are VIEs or voting interest entities, eliminates the presumption that a general partner should consolidate a limited partnership, and affects the consolidation analysis of reporting entities that are involved with VIEs. January 2016 The adoption of this standard resulted in five additional investment partnerships being considered variable interest entities due to the limited partners' lack of substantive participation in the partnerships. This did not result in any impact to the Company's Consolidated Balance Sheets, Statements of Operations, or Cash Flows, but did result in additional disclosures about its relationships with and exposure to variable interest entities. ASU 2015-03, April 2015, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs ASU 2015-03 simplifies the presentation of debt issuance costs by requiring that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. January 2016 The adoption and implementation of this standard has resulted in the retrospective presentation of debt issuance costs associated with the Company's notes payable and term loans as a direct deduction from the carrying amount of the related debt instruments (previously, included in deferred costs in the consolidated balance sheets). Unamortized debt issuance costs of $8.2 million has been reclassified to offset the related debt as of December 31, 2015. ASU 2015-15, August 2015, Interest—Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements ASU 2015-15 clarifies that debt issuance costs related to line-of-credit arrangements may be deferred and presented as an asset, amortized over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings. January 2016 The adoption of this standard resulted in debt issuance costs related to the Line of credit ("Line") to continue being presented as an asset in the Consolidated Balance Sheets, previously within deferred costs, and now presented within other assets. Standard Description Date of adoption Effect on the financial statements or other significant matters Not yet adopted: ASU 2014-15, August 2014, Presentation of Financial Statements—Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern The standard requires management to evaluate whether there are conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern, and to provide certain disclosures when it is probable that the entity will be unable to meet its obligations as they become due within one year after the date that the financial statements are issued. December 2016 The Company does not expect the adoption of this standard to have an impact on its Consolidated Balance Sheets, Statements of Operations, or Cash Flows but will result in more disclosure surrounding the Company's plans for addressing significant upcoming debt maturities. ASU 2016-09, March 2016, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting This ASU affects entities that issue share-based payment awards to their employees. The ASU is designed to simplify several aspects of accounting for share-based payment award transactions including income tax consequences, classification of awards as either equity or liabilities, an option to recognize stock compensation forfeitures as they occur, and changes to classification on the statement of cash flows. January 2017 The Company does not expect the adoption of this standard to have an impact on its financial statements and related disclosures. Revenue from Contracts with Customers (Topic 606): ASU 2014-09, May 2014, Revenue from Contracts with Customers (Topic 606) ASU 2016-08, March 2016, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations ASU 2016-10, April 2016, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing ASU 2016-12, May 2016, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients The standard will replace existing revenue recognition standards and significantly expand the disclosure requirements for revenue arrangements. It may be adopted either retrospectively or on a modified retrospective basis to new contracts and existing contracts with remaining performance obligations as of the effective date. January 2018 The Company is currently evaluating the alternative methods of adoption and the impact it may have on its financial statements and related disclosures. Standard Description Date of adoption Effect on the financial statements or other significant matters ASU 2016-01, January 2016, Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities The standard amends the guidance to classify equity securities with readily-determinable fair values into different categories and requires equity securities to be measured at fair value with changes in the fair value recognized through net income. Equity investments accounted for under the equity method are not included in the scope of this amendment. Early adoption of this amendment is not permitted. January 2018 The Company does not expect the adoption and implementation of this standard to have a material impact on its results of operations, financial condition or cash flows. ASU 2016-15, August 2016, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments The standard will make eight targeted changes to how cash receipts and cash payments are presented and classified in the statement of cash flows. Early adoption is permitted on a retrospective basis. January 2018 The ASU is consistent with the Company's current treatment and the Company does not expect the adoption and implementation of this standard to have an impact on its cash flow statement. ASU 2016-02, February 2016, Leases (Topic 842) The standard amends the existing accounting standards for lease accounting, including requiring lessees to recognize most leases on their balance sheets. It also makes targeted changes to lessor accounting, including a change to the treatment of initial direct leasing costs, which no longer considers fixed internal leasing salaries as capitalizable costs. Early adoption of this standard is permitted to coincide with adoption of ASU 2014-09. The standard requires a modified retrospective transition approach for all leases existing at, or entered into after, the date of initial application, with an option to use certain transition relief. January 2019 The Company is currently evaluating the alternative methods of adoption and the impact it will have on its financial statements and related disclosures. ASU 2016-13, June 2016 , Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments The amendments in this update replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. January 2020 The Company is currently evaluating the alternative methods of adoption and the impact it will have on its financial statements and related disclosures.
Consolidation, Variable Interest Entity, Policy [Policy Text Block]	Real Estate Partnerships Regency has an ownership interest in 121 properties through partnerships, of which 11 are consolidated, with institutional investors, other real estate developers and/or operators, and individual parties who help Regency source transactions for development and investment ("the Partners", "limited partners"). Regency has a variable interest in these entities through its equity interests. As managing member, Regency maintains the books and records and typically provides leasing and property management to the partnerships. The partners’ level of involvement varies from protective decisions (debt, bankruptcy, selling primary asset(s) of business) to involvement in approving leases, operating budgets, and capital budgets. • Those partnerships for which the partners only have protective rights are considered VIEs under ASC 810, Consolidation. Regency is the primary beneficiary of these VIEs as Regency has power over these partnerships and they operate primarily for the benefit of Regency. As such, Regency consolidates these entities and reports the limited partners’ interest as noncontrolling interests. The majority of the operations of the VIEs are funded with cash flows generated by the properties, or in the case of developments, with capital contributions or third party construction loans. Regency does not provide financial support to the VIEs. • Those partnerships for which the partners are involved in the day to day decisions and do not have any other aspects that would cause them to be considered VIEs, are evaluated for consolidation using the voting interest model. ◦ Those partnerships in which Regency has a controlling financial interest are consolidated and the limited partners’ ownership interest and share of net income is recorded as noncontrolling interest. ◦ Those partnerships in which Regency does not have a controlling financial interest are accounted for using the equity method and its ownership interest is recognized through single-line presentation as Investments in Real Estate Partnerships, in the Consolidated Balance Sheet, and Equity in Income of Investments in Real Estate Partnerships, in the Consolidated Statements of Operations. Distributions received from these partnerships are accounted for using the look-through method with returns of capital from property sales or debt financing considered investing cash flows and the remaining distributions generally considered operating cash flows. 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 these partnerships can only be settled by the assets of these partnerships.
Consolidation, Policy [Policy Text Block]	Consolidation The Company consolidates properties that are wholly owned or properties where it owns less than 100%, but which it controls. Control is determined using an evaluation based on accounting standards related to the consolidation of voting interest entities and variable interest entities ("VIEs"). For joint ventures that are determined to be a VIE, the Company consolidates the entity where it is deemed to be the primary beneficiary. Determination of the primary beneficiary is based on whether an entity has (1) the power to direct the activities of the VIE that most significantly impact the entity's economic performance, and (2) the obligation to absorb losses of the entity that could potentially be significant to the VIE or the right to receive benefits from the entity that could potentially be significant to the VIE. The Company's determination of the primary beneficiary considers all relationships between it and the VIE, including management agreements and other contractual arrangements. Ownership of the Operating Partnership The Operating Partnership’s capital includes general and limited common Partnership Units. As of September 30, 2016 , the Parent Company owned approximately 99.9% of the outstanding common Partnership Units of the Operating Partnership with the remaining limited Partnership Units held by third parties (“Exchangeable operating partnership units” or “EOP units”). 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 characteristics of a controlling financial interest. As such, the Operating Partnership is considered a variable interest entity, and the Parent Company is the primary beneficiary which consolidates it. The Parent Company’s only investment is the Operating Partnership.
