Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business, Basis of Presentation and Significant Accounting Policies and Recently Issued Accounting Pronouncements	Description of Business, Basis of Presentation, Significant Accounting Policies and Recently Issued Accounting Pronouncements (a) Description of Business Heritage Financial Corporation is a bank holding company that was incorporated in the State of Washington in August 1997. The Company is primarily engaged in the business of planning, directing and coordinating the business activities of its wholly-owned subsidiary, Heritage Bank. The Bank is a Washington-chartered commercial bank and its deposits are insured by the FDIC. The Bank is headquartered in Olympia, Washington and conducts business from its 62 branch offices as of September 30, 2019 located throughout Washington State and the greater Portland, Oregon area. The Bank’s business consists primarily of commercial lending and deposit relationships with small businesses and their owners in its market areas and attracting deposits from the general public. The Bank also makes real estate construction and land development loans, consumer loans and originates first mortgage loans on residential properties primarily located in its market areas. Effective January 16, 2018, the Company completed the Puget Sound Merger and on July 2, 2018, the Company completed the Premier Merger, collectively called the "Premier and Puget Mergers." See Note (2) Business Combinations for additional information on the Premier and Puget Mergers. (b) Basis of Presentation The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with GAAP for interim financial information and pursuant to the rules and regulations of the SEC. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. It is recommended that these unaudited Condensed Consolidated Financial Statements and accompanying Notes be read with the audited Consolidated Financial Statements and the accompanying Notes included in the 2018 Annual Form 10-K. In management's opinion, all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair presentation have been included. Operating results for the three and nine months ended September 30, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019 . In preparing the unaudited Condensed Consolidated Financial Statements, management is required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosures. Management believes that the judgments, estimates and assumptions used in the preparation of the financial statements are appropriate based on the facts and circumstances at the time. Actual results, however, could differ significantly from those estimates. (c) Significant Accounting Policies The significant accounting policies used in preparation of the Company's Condensed Consolidated Financial Statements are disclosed in the 2018 Annual Form 10-K. There have not been any material changes in the Company's significant accounting policies from those contained in the 2018 Annual Form 10-K, except for the accounting policy relating to operating leases adopted January 1, 2019, as discussed below. Operating leases During the normal course of business, the Company enters into agreements, and at inception it determines if a particular agreement is a lease. The Company's noncancelable operating lease agreements relate to certain banking offices, back-office operational facilities, office equipment, and sublease agreements. The agreements are recorded as ROU assets and liabilities within prepaid expenses and other assets and accrued expenses and other liabilities, respectively, in the Condensed Consolidated Statements of Financial Condition. Operating lease ROU assets and lease liabilities are recognized at the commencement date based on the present value of lease payments over the lease term, and represent the right to use an underlying asset for the lease term and the obligation to make lease payments arising from the lease. As the Company's leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The operating lease ROU asset also includes any lease pre-payments made and excludes lease incentives. The Company's lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The Company elected an exclusion policy for ROU assets and liabilities for operating leases with a term of twelve months or less and a capitalization threshold policy for total contractual lease payments of $25,000 or more. The Company does not account for any leases at a portfolio level. (d) Recently Issued Accounting Pronouncements FASB ASU 2016-02 , Leases (Topic 842), as amended by ASU 2017-13, 2018-01, 2018-10, ASU 2018-11, and ASU 2019-01 was originally issued in February 2016, to increase transparency and comparability of leases among organizations and to disclose key information about leasing arrangements. The ASU sets out the principles for the recognition, measurement, presentation and disclosure of leases for both lessees and lessors. The Company adopted the ASU on January 1, 2019 and elected the package of practical expedients permitted under the transition guidance within the new standard, which allowed the Company to carry forward the historical determination of contracts as leases, to carry forward lease classifications, and to not reassess initial direct costs for historical lease arrangements. The adoption of this ASU resulted in the initial recognition of operating lease ROU assets and liabilities of approximately $29.2 million and $29.8 million , respectively, in prepaid expenses and other assets and accrued expenses and other liabilities in the Condensed Consolidated Statements of Financial Condition. This change also resulted in a cumulative-effect adjustment to beginning retained earnings of $399,000 , net of tax, under the modified retrospective approach. As a result of electing this transition method, prior periods have not been restated. FASB ASU 2016-13 , Financial Instruments: Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , as amended by ASU 2018-19, ASU 2019-04 and ASU 2019-05, was originally issued in June 2016. Commonly referred to as CECL, this ASU requires financial assets measured at amortized cost basis to be presented at the net amount expected to be collected. For public business entities, this ASU is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years with early adoption permitted for fiscal years after December 15, 2018. The Company is anticipating adopting the Update on January 1, 2020. Upon adoption, the Company expects a change in the processes, internal controls and procedures to calculate the allowance for loan losses, including changes in assumptions and estimates to consider expected credit losses over the life of the loan versus the current accounting practice that utilizes the incurred loss model. In addition, the current accounting policy and procedures for other-than-temporary impairment on investment securities available for sale will be replaced with an allowance approach. The new guidance may result in an increase in the allowance for loan losses which will also reflect the new requirement to include the nonaccretable principal differences on PCI loans; however, the Company is still in the process of determining the magnitude of the increase and its impact on the Condensed Consolidated Financial Statements. During 2017, the Company's management created a CECL steering committee to develop and implement processes and procedures to ensure it is fully compliant with the amendments at the adoption date. In late 2017 the CECL steering committee selected a vendor to assist the Company in the adoption of a model, completed the implementation discovery sessions, and selected an appropriate methodology. During 2019, the Company compiled historical loan data and finalized data queries from the core system for current periods. Management is finalizing assumptions used in the model and running and analyzing CECL ALLL outcomes. The Company anticipates providing an estimated ALLL under the CECL model in January 2020. FASB ASU 2017-04 , Goodwill (Topic 350) , was issued in January 2017 and eliminates Step 2 from the goodwill impairment test. The ASU is effective for annual periods or any interim goodwill impairment tests beginning after December 15, 2019 using a prospective transition method and early adoption is permitted. The Company does not expect the ASU will have a material impact on its Condensed Consolidated Financial Statements. FASB ASU 2018-13 , Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement, was issued in August 2018 and modifies the disclosure requirements on fair value measurements in Topic 820. The amendments in this ASU are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The Company does not expect the ASU will have a material impact on its Condensed Consolidated Financial Statements.

None of the underlying issuers of the municipal securities and corporate obligations had credit ratings that were below investment grade levels at September 30, 2019 or December 31, 2018 .

Loans and Leases Receivable Disclosure [Abstract]
Financing Receivables [Text Block]	Loans Receivable (a) Loan Origination/Risk Management The Company originates loans in the ordinary course of business and has also acquired loans through mergers and acquisitions. Disclosures related to the Company's recorded investment in loans receivable generally exclude accrued interest receivable and net deferred fees or costs as they were deemed insignificant. Loans acquired in a business combination are further classified as “purchased” loans. Loans purchased with evidence of credit deterioration since origination for which it is probable that not all contractually required payments will be collected are accounted for under FASB ASC 310-30, Receivables —Loans and Debt Securities Acquired with Deteriorated Credit Quality . These loans are identified as "PCI" loans. Loans purchased that are not accounted for under FASB ASC 310-30 are accounted for under FASB ASC 310-20, Receivables—Nonrefundable Fees and Other Costs, and are referred to as "non-PCI" loans. There were no PCI loans acquired in the Premier and Puget Mergers. The Company categorizes loans in one of the four segments of the total loan portfolio: commercial business, one-to-four family residential, real estate construction and land development and consumer. Within these segments are classes of loans for which management monitors and assesses credit risk in the loan portfolios. Loans receivable at September 30, 2019 and December 31, 2018 consisted of the following portfolio segments and classes: September 30, 2019 December 31, 2018 (In thousands) Commercial business: Commercial and industrial $ 853,995 $ 853,606 Owner-occupied commercial real estate 787,591 779,814 Non-owner occupied commercial real estate 1,316,992 1,304,463 Total commercial business 2,958,578 2,937,883 One-to-four family residential 121,174 101,763 Real estate construction and land development: One-to-four family residential 98,034 102,730 Five or more family residential and commercial properties 147,686 112,730 Total real estate construction and land development 245,720 215,460 Consumer 403,485 395,545 Gross loans receivable 3,728,957 3,650,651 Net deferred loan costs 2,386 3,509 Loans receivable, net 3,731,343 3,654,160 Allowance for loan losses (36,518 ) (35,042 ) Total loans receivable, net $ 3,694,825 $ 3,619,118 (b) Concentrations of Credit As of September 30, 2019 , and December 31, 2018 , there were no concentrations of loans related to any single industry in excess of 10% of the Company’s total loans. (c) Credit Quality Indicators As part of the on-going monitoring of the credit quality of the Company’s loan portfolio, management tracks certain credit quality indicators including trends related to (i) the risk grade of the loans, (ii) the level of classified loans, (iii) net charge-offs, (iv) nonperforming loans and (v) the general economic conditions of the United States of America, and specifically the states of Washington and Oregon. The Company utilizes a risk grading matrix to assign a risk grade to each loan on a scale of 1 to 10. Risk grades are aggregated to create the risk categories of "Pass" for grades 1 to 6, OAEM for grade 7, "Substandard" for grade 8, "Doubtful" for grade 9 and "Loss" for grade 10. The following tables present the balance of loans receivable by credit quality indicator as of September 30, 2019 and December 31, 2018 : September 30, 2019 Pass OAEM Substandard Doubtful/Loss Total (In thousands) Commercial business: Commercial and industrial $ 777,165 $ 20,310 $ 56,520 $ — $ 853,995 Owner-occupied commercial real estate 753,386 20,498 13,707 — 787,591 Non-owner occupied commercial real estate 1,293,780 9,989 13,223 — 1,316,992 Total commercial business 2,824,331 50,797 83,450 — 2,958,578 One-to-four family residential 119,914 — 1,260 — 121,174 Real estate construction and land development: One-to-four family residential 96,300 — 1,734 — 98,034 Five or more family residential and commercial properties 147,177 509 — — 147,686 Total real estate construction and land development 243,477 509 1,734 — 245,720 Consumer 399,203 — 3,758 524 403,485 Gross loans receivable $ 3,586,925 $ 51,306 $ 90,202 $ 524 $ 3,728,957 December 31, 2018 Pass OAEM Substandard Doubtful/Loss Total (In thousands) Commercial business: Commercial and industrial $ 788,395 $ 16,168 $ 49,043 $ — $ 853,606 Owner-occupied commercial real estate 741,227 27,724 10,863 — 779,814 Non-owner occupied commercial real estate 1,283,077 9,438 11,948 — 1,304,463 Total commercial business 2,812,699 53,330 71,854 — 2,937,883 One-to-four family residential 100,401 — 1,362 — 101,763 Real estate construction and land development: One-to-four family residential 101,519 258 953 — 102,730 Five or more family residential and commercial properties 112,678 52 — — 112,730 Total real estate construction and land development 214,197 310 953 — 215,460 Consumer 390,808 — 4,213 524 395,545 Gross loans receivable $ 3,518,105 $ 53,640 $ 78,382 $ 524 $ 3,650,651 Potential problem loans are loans classified as OAEM or worse that are currently accruing interest and are not considered impaired, but which management is closely monitoring because the financial information of the borrower causes concern as to their ability to meet their loan repayment terms. Potential problem loans may include PCI loans as these loans continue to accrete loan discounts established at acquisition based on the guidance of FASB ASC 310-30. Potential problem loans as of September 30, 2019 and December 31, 2018 were $85.3 million and $101.3 million , respectively.

(e) Past due loans The Company performs an aging analysis of past due loans using policies consistent with regulatory reporting requirements with categories of 30-89 days past due and 90 or more days past due. PCI loans are included in the past due loans table below solely to reconcile to total Gross Loans Receivable. The balances of past due loans, segregated by segments and classes of loans, as of September 30, 2019 and December 31, 2018 were as follows: September 30, 2019 30-89 Days 90 Days or Greater Total Past Due Current Total (In thousands) Commercial business: Commercial and industrial $ 832 $ 3,562 $ 4,394 $ 847,202 $ 851,596 Owner-occupied commercial real estate 158 757 915 779,880 780,795 Non-owner occupied commercial real estate 2,971 2,029 5,000 1,305,725 1,310,725 Total commercial business 3,961 6,348 10,309 2,932,807 2,943,116 One-to-four family residential — — — 117,669 117,669 Real estate construction and land development: One-to-four family residential — 560 560 97,474 98,034 Five or more family residential and commercial properties — — — 147,686 147,686 Total real estate construction and land development — 560 560 245,160 245,720 Consumer 1,667 — 1,667 399,717 401,384 Past due gross loans receivable, excluding PCI loans 5,628 6,908 12,536 3,695,353 3,707,889 PCI loans 934 155 1,089 19,979 21,068 Gross loans receivable $ 6,562 $ 7,063 $ 13,625 $ 3,715,332 $ 3,728,957 December 31, 2018 30-89 Days 90 Days or Greater Total Past Due Current Total (In thousands) Commercial business: Commercial and industrial $ 2,711 $ 2,281 $ 4,992 $ 845,181 $ 850,173 Owner-occupied commercial real estate 513 408 921 771,677 772,598 Non-owner occupied commercial real estate 3,412 1,103 4,515 1,292,888 1,297,403 Total commercial business 6,636 3,792 10,428 2,909,746 2,920,174 One-to-four family residential 227 — 227 98,221 98,448 Real estate construction and land development: One-to-four family residential 665 234 899 101,451 102,350 Five or more family residential and commercial properties — — — 112,688 112,688 Total real estate construction and land development 665 234 899 214,139 215,038 Consumer 2,559 — 2,559 389,525 392,084 Past due gross loans receivable, excluding PCI loans 10,087 4,026 14,113 3,611,631 3,625,744 PCI loans 2,271 550 2,821 22,086 24,907 Gross loans receivable $ 12,358 $ 4,576 $ 16,934 $ 3,633,717 $ 3,650,651 There were no loans 90 days or more past due that were still accruing interest as of September 30, 2019 or December 31, 2018 , excluding PCI loans.

Loans that were modified as TDR loans during the three and nine months ended September 30, 2019 and 2018 are set forth in the following tables: Three Months Ended September 30, 2019 2018 Number of Recorded Investment (1) Number of Recorded Investment (1) (Dollars in thousands) Commercial business: Commercial and industrial 15 $ 5,266 11 $ 2,352 Owner-occupied commercial real estate 2 1,214 2 1,081 Non-owner occupied commercial real estate 3 2,597 2 2,776 Total commercial business 20 9,077 15 6,209 Consumer 3 26 1 25 Total loans modified as TDR loans 23 $ 9,103 16 $ 6,234 Nine Months Ended September 30, 2019 2018 Number of (2) Recorded Investment (1,2) Number of Contracts (2) Recorded Investment (1,2) (Dollars in thousands) Commercial business: Commercial and industrial 33 $ 22,414 22 $ 4,445 Owner-occupied commercial real estate 3 1,612 3 1,639 Non-owner occupied commercial real estate 4 5,568 3 2,976 Total commercial business 40 29,594 28 9,060 Real estate construction and land development: One-to-four family residential 1 560 2 767 Consumer 10 155 8 133 Total TDR loans 51 $ 30,309 38 $ 9,960 (1) Includes subsequent payments after modifications and reflects the balance as of period end. As the Bank did not forgive any principal or interest balance as part of the loan modification, the Bank’s recorded investment in each loan at the date of modification (pre-modification) did not change as a result of the modification (post-modification), except when the modification was the initial advance on a one-to-four family residential real estate construction and land development loan under a master guidance line. There were no advances on these types of loans during the three and nine months ended September 30, 2019 and 2018 . (2) Number of contracts and outstanding principal balance represent loans which have balances as of period end as certain loans may have been paid-down or charged-off during the nine months ended September 30, 2019 and 2018 . The tables above include seven and 17 loans, respectively, for the three and nine months ended September 30, 2019 and nine and 15 loans, respectively, for the three and nine months ended September 30, 2018 that were previously reported as TDR loans. The Bank typically grants shorter extension periods to continually monitor these TDR loans despite the fact that the extended date might not be the date the Bank expects sufficient cash flow from these borrowers. The Bank does not consider these modifications a subsequent default of a TDR as new loan terms, specifically new maturity dates, were granted. Of the remaining first-reported TDR loans, the concessions granted largely consisted of maturity extensions, interest rate modifications or a combination of both. The potential losses related to TDR loans are considered in the period the loan was first reported as a TDR loan and are adjusted, as necessary, in the current period based on more recent information. The related specific valuation allowance at September 30, 2019 for loans that were modified as TDR loans during the nine months ended September 30, 2019 was $1.8 million . Loans that were modified during the previous twelve months that subsequently defaulted during the three and nine months ended September 30, 2019 and 2018 are set forth in the following tables: Three Months Ended September 30, 2019 2018 Number of Contracts Recorded Investments Number of Recorded Investments (Dollars in thousands) Commercial business: Commercial and industrial 4 $ 2,056 2 $ 1,742 Non-owner occupied commercial real estate 1 2,971 — — Total commercial business 5 5,027 2 1,742 Total 5 $ 5,027 2 $ 1,742 Nine Months Ended September 30, 2019 2018 Number of Contracts (1) Recorded Investments (1) Number of (1) Recorded Investments (1) (Dollars in thousands) Commercial business: Commercial and industrial 9 $ 3,230 3 $ 2,020 Owner-occupied commercial real estate 2 1,101 1 69 Non-owner occupied commercial real estate 2 3,541 — — Total commercial business 13 7,872 4 2,089 Real estate construction and land development: One-to-four family residential 1 560 2 767 Total 14 $ 8,432 6 $ 2,856 (1) Number of contracts and outstanding principal balance represent loans which have balances as of period end as certain loans may have been paid-down or charged-off during the nine months ended September 30, 2019 and 2018 . During the three and nine months ended September 30, 2019 , three and 12 TDR loans, respectively, defaulted because each was past its modified maturity date, and the borrower has not subsequently repaid the credits. The Bank has chosen not to extend further the maturity date on these loans. In addition, during both the three and nine months ended September 30, 2019 , two TDR loans defaulted because the borrowers were more than 90 days delinquent on their scheduled loan payments. The Bank had a specific valuation allowance of $412,000 at September 30, 2019 related to these TDR loans which defaulted during the nine months ended September 30, 2019 . During the three and nine months ended September 30, 2018 , two and three TDR loans, respectively, defaulted because each was past its modified maturity date, and the borrower has not subsequently repaid the credits.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets (a) Goodwill The Company’s goodwill represents the excess of the purchase price over the fair value of net assets acquired in the following mergers and acquisitions: Premier Commercial Bancorp on July 2, 2018; Puget Sound Bancorp on January 16, 2018; Washington Banking Company on May 1, 2014; Valley Community Bancshares on July 15, 2013; Western Washington Bancorp in 2006 and North Pacific Bank in 1998. The Company’s goodwill is assigned to the Bank and is evaluated for impairment at the Bank level (reporting unit). The following table presents the change in goodwill for the periods indicated: Three Months Ended September 30, Nine Months Ended 2019 2018 2019 2018 (In thousands) Balance at the beginning of the period $ 240,939 $ 187,549 $ 240,939 $ 119,029 Additions as a result of acquisitions (1) — 53,288 — 121,808 Balance at the end of the period $ 240,939 $ 240,837 $ 240,939 $ 240,837 (1) See Note (2) Business Combinations The Company performed its annual goodwill impairment test during the fourth quarter of 2018 and determined based on its Step 1 analysis that the fair value of the reporting unit exceeded the carrying value, such that the Company's goodwill was not considered impaired. Changes in the economic environment, operations of the reporting unit or other adverse events could result in future impairment charges which could have a material impact on the Company’s operating results. No events or circumstances since the annual impairment test were noted that would indicate it was more likely than not a goodwill impairment existed during the nine months ended September 30, 2019. (b) Other Intangible Assets Other intangible assets represent CDI acquired in business combinations. The useful life of the CDI was estimated to be ten years for the acquisitions of Premier Commercial Bancorp, Puget Sound Bancorp, Washington Banking Company, and Valley Community Bancshares, and was estimated to be five years for the acquisition of Northwest Commercial Bank. The following table presents the change in other intangible assets for the periods indicated: Three Months Ended September 30, Nine Months Ended 2019 2018 2019 2018 (In thousands) Balance at the beginning of the period $ 18,563 $ 15,767 $ 20,614 $ 6,088 Additions as a result of acquisitions (1) — 7,075 — 18,345 Amortization (975 ) (1,114 ) (3,026 ) (2,705 ) Balance at the end of the period $ 17,588 $ 21,728 $ 17,588 $ 21,728 (1) See Note (2) Business Combinations

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments The Company has entered into certain interest rate swap contracts that are not designated as hedging instruments. The purpose of these derivative contracts is primarily to provide commercial business loan customers the ability to convert their loans from variable to fixed interest rates. Upon the origination of a derivative contract with a customer, the Company simultaneously enters into an offsetting derivative contract with a third party in order to offset its exposure on the variable and fixed rate components of the customer agreement. The Company recognizes immediate income based upon the difference in the bid/ask spread of the underlying transactions with its customers and the third party, which is recorded in interest rate swap fees on the Condensed Consolidated Statements of Income. Because the Company acts only as an intermediary for its customer, subsequent changes in the fair value of the underlying derivative contracts offset each other and do not significantly impact the Company’s results of operations. The following table presents the notional amounts and estimated fair values of interest rate derivative contracts outstanding at September 30, 2019 and December 31, 2018 : September 30, 2019 December 31, 2018 Notional Amounts Estimated Fair Value Notional Amounts Estimated Fair Value (In thousands) Non-hedging interest rate derivatives Interest rate swap asset (1) $ 181,360 $ 12,026 $ 171,798 $ 5,095 Interest rate swap liability (1) 181,360 (12,026 ) 171,798 (5,095 ) (1) The estimated fair value of derivatives with customers was $12,026 and $(1,643) as of September 30, 2019 and December 31, 2018 , respectively.

Potential dilutive shares are excluded from the computation of earnings per share if their effect is anti-dilutive. Anti-dilution occurs when the exercise price of a stock option or the unrecognized compensation cost per share of a restricted stock award exceeds the market price of the Company’s stock. For the three and nine months ended September 30, 2019 , there were 108,501 and 70,372 anti-dilutive shares outstanding, respectively. There were no anti-dilutive shares outstanding for the three and nine months ended September 30, 2018 . (b) Dividends The timing and amount of cash dividends paid on the Company's common stock depends on the Company’s earnings, capital requirements, financial condition and other relevant factors. Dividends on common stock from the Company depend substantially upon receipt of dividends from the Bank, which is the Company’s predominant source of income. The following table summarizes the dividend activity for the nine months ended September 30, 2019 and calendar year 2018 : Declared Cash Dividend per Share Record Date Paid Date January 24, 2018 $0.15 February 7, 2018 February 21, 2018 April 25, 2018 $0.15 May 10, 2018 May 24, 2018 July 24, 2018 $0.15 August 9, 2018 August 23, 2018 October 24, 2018 $0.17 November 7, 2018 November 21, 2018 October 24, 2018 $0.10 November 7, 2018 November 21, 2018 * January 23, 2019 $0.18 February 7, 2019 February 21, 2019 April 24, 2019 $0.18 May 8, 2019 May 22, 2019 July 24, 2019 $0.19 August 8, 2019 August 22, 2019 * Denotes a special dividend. The FDIC and the Washington State Department of Financial Institutions, Division of Banks have the authority under their supervisory powers to prohibit the payment of dividends by the Bank to the Company. Additionally, current guidance from the Federal Reserve provides, among other things, that dividends per share on the Company’s common stock generally should not exceed earnings per share, measured over the previous four fiscal quarters. Current regulations allow the Company and the Bank to pay dividends on their common stock if the Company’s or the Bank’s regulatory capital would not be reduced below the statutory capital requirements set by the Federal Reserve and the FDIC. (c) Stock Repurchase Program The Company has had various stock repurchase programs since March 1999. On October 23, 2014, the Company's Board of Directors authorized the repurchase of up to 5% of the Company's outstanding common shares, or approximately 1,513,000 shares, under the eleventh stock repurchase plan. The number, timing and price of shares repurchased will depend on business and market conditions and other factors, including opportunities to deploy the Company's capital. Since the inception of the eleventh plan, the Company has repurchased 872,678 shares at an average share price of $20.03 , including 264,712 and 292,712 shares repurchased at an average share price of $26.23 and $26.50 during the three and nine months ended September 30, 2019 , respectively. No shares were repurchased under this plan during the three and nine months ended September 30, 2018 . In addition to the stock repurchases under a plan, the Company repurchases shares to pay withholding taxes on the vesting of restricted stock awards and units. The following table provides total repurchased shares for the periods indicated: Three Months Ended September 30, Nine Months Ended 2019 2018 2019 2018 Repurchased shares to pay withholding taxes (1) 405 368 28,434 53,188 Stock repurchase to pay withholding taxes average share price $ 27.67 $ 36.34 $ 30.83 $ 31.99 (1) During the nine months ended September 30, 2018 , the Company repurchased 26,741 shares related to the withholding taxes due on the accelerated vesting of the restricted stock units of Puget Sound which were converted to Heritage common stock shares with an average share price of $31.80 under the terms of the Puget Sound Merger.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair values: Level 1 : Valuations for assets and liabilities traded in active exchange markets, or interest in open-end mutual funds that allow the Company to sell its ownership interest back to the fund at net asset value on a daily basis. Valuations are obtained from readily available pricing sources for market transactions involving identical assets, liabilities, or funds. Level 2 : Valuations for assets and liabilities traded in less active dealer or broker markets, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or valuations using methodologies with observable inputs. Level 3 : Valuations for assets and liabilities that are derived from other valuation methodologies, such as option pricing models, discounted cash flow models and similar techniques using unobservable inputs, and not based on market exchange, dealer, or broker traded transactions. Level 3 valuations incorporate certain assumptions and projections in determining the fair value assigned to such assets or liabilities. (a) Recurring and Nonrecurring Basis The Company used the following methods and significant assumptions to measure the fair value of certain assets on a recurring and nonrecurring basis: Investment Securities Available for Sale : The fair values of all investment securities are based upon the assumptions that market participants would use in pricing the security. If available, fair values of investment securities are determined by quoted market prices (Level 1). For investment securities where quoted market prices are not available, fair values are calculated based on market prices on similar securities (Level 2). For investment securities where quoted prices or market prices of similar securities are not available, fair values are calculated by using observable and unobservable inputs such as discounted cash flows or other market indicators (Level 3). Security valuations are obtained from third party pricing services for comparable assets or liabilities. Impaired Loans : At the time a loan is considered impaired, its impairment is measured based on either the present value of expected future cash flows discounted at the loan’s effective interest rate, the observable market price, or the fair market value of the collateral (less costs to sell) if the loan is collateral-dependent. Impaired loans for which impairment is measured using the discounted cash flow approach are not considered to be measured at fair value because the loan’s effective interest rate is generally not a fair value input, and for the purposes of fair value disclosures, the fair value of these loans are measured commensurate with non-impaired loans. If the Company utilizes the fair market value of the collateral method, the fair value used to measure impairment is commonly based on recent real estate appraisals. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by independent appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are usually significant and typically result in a Level 3 classification of the inputs for determining fair value. Non-real estate collateral may be valued using an appraisal, net book value based on the borrower’s financial statements, or aging reports, adjusted or discounted based on management’s historical knowledge, changes in market conditions from the time of the valuation and management’s expertise and knowledge of the client and client’s business (Level 3). Impaired loans are evaluated on a quarterly basis and impairment is adjusted accordingly. Other Real Estate Owned : Assets acquired through or instead of loan foreclosure are initially recorded at fair value less costs to sell when acquired, establishing a new cost basis. These assets are subsequently accounted for at lower of cost or fair value less costs to sell. Fair value is commonly based on recent real estate appraisals. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by independent appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are usually significant and typically result in Level 3 classification of the inputs for determining fair value. Appraisals for both collateral-dependent impaired loans and other real estate owned are performed by certified general appraisers for commercial properties or certified residential appraisers for residential properties whose qualifications and licenses have been reviewed and verified by the Company. Once received, the Company reviews the assumptions and approaches utilized in the appraisal as well as the resulting fair value in comparison with independent data sources such as recent market data or industry-wide statistics. On a quarterly basis, the Company compares the actual selling price of collateral that has been liquidated to the most recent appraised value to determine what additional adjustment should be made to the appraisal value to arrive at fair value. Derivative Financial Instruments: The Company obtains broker or dealer quotes to value its interest rate derivative contracts, which use valuation models using observable market data as of the measurement date (Level 2). The following tables summarize the balances of assets and liabilities measured at fair value on a recurring basis as of September 30, 2019 and December 31, 2018 : September 30, 2019 Total Level 1 Level 2 Level 3 (In thousands) Assets Investment securities available for sale: U.S. Treasury and U.S. Government-sponsored agencies $ 112,851 $ 16,090 $ 96,761 $ — Municipal securities 127,315 — 127,315 — Mortgage-backed securities and collateralized mortgage obligations: Residential 346,677 — 346,677 — Commercial 331,330 — 331,330 — Corporate obligations 24,156 — 24,156 — Other asset-backed securities 23,773 — 23,773 — Total investment securities available for sale 966,102 16,090 950,012 — Equity Security 147 147 — — Derivative assets - interest rate swaps 12,026 — 12,026 — Liabilities Derivative liabilities - interest rate swaps $ 12,026 $ — $ 12,026 $ — December 31, 2018 Total Level 1 Level 2 Level 3 (In thousands) Assets Investment securities available for sale: U.S. Treasury and U.S. Government-sponsored agencies $ 101,603 $ 15,936 $ 85,667 $ — Municipal securities 158,864 — 158,864 — Mortgage-backed securities and collateralized mortgage obligations: Residential 331,602 — 331,602 — Commercial 333,761 — 333,761 — Corporate obligations 25,563 — 25,563 — Other asset-backed securities 24,702 — 24,702 — Total investment securities available for sale 976,095 15,936 960,159 — Equity Security 114 114 — — Derivative assets - interest rate swaps 5,095 — 5,095 — Liabilities Derivative liabilities - interest rate swaps $ 5,095 $ — $ 5,095 $ — There were no transfers between Level 1 and Level 2 during the three and nine months ended September 30, 2019 and 2018 . Nonrecurring Basis The Company may be required to measure certain financial assets and liabilities at fair value on a nonrecurring basis. These adjustments to fair value usually result from application of lower-of-cost-or-market accounting or write-downs of individual assets. The following tables below represent assets measured at fair value on a nonrecurring basis at September 30, 2019 and December 31, 2018 and the net losses recorded in earnings during three and nine months ended September 30, 2019 and 2018 : Basis (1) Fair Value at September 30, 2019 Total Level 1 Level 2 Level 3 Net Losses Net Losses (In thousands) Impaired loans: Commercial and industrial $ 2,503 $ 1,872 $ — $ — $ 1,872 $ 48 $ 134 Total assets measured at fair value on a nonrecurring basis $ 2,503 $ 1,872 $ — $ — $ 1,872 $ 48 $ 134 (1) Basis represents the unpaid principal balance of impaired loans.

These determinations are subjective in nature, involve uncertainties and matters of significant judgment and do not include tax ramifications; therefore, the results cannot be determined with precision, substantiated by comparison to independent markets and may not be realized in an actual sale or immediate settlement of the instruments. There may be inherent weaknesses in any calculation technique, and changes in the underlying assumptions used, including discount rates and estimates of future cash flows, could significantly affect the results. For all of these reasons, the aggregation of the fair value calculations presented herein do not represent, and should not be construed to represent, the underlying value of the Company.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business	Description of Business Heritage Financial Corporation is a bank holding company that was incorporated in the State of Washington in August 1997. The Company is primarily engaged in the business of planning, directing and coordinating the business activities of its wholly-owned subsidiary, Heritage Bank. The Bank is a Washington-chartered commercial bank and its deposits are insured by the FDIC. The Bank is headquartered in Olympia, Washington and conducts business from its 62 branch offices as of September 30, 2019 located throughout Washington State and the greater Portland, Oregon area. The Bank’s business consists primarily of commercial lending and deposit relationships with small businesses and their owners in its market areas and attracting deposits from the general public. The Bank also makes real estate construction and land development loans, consumer loans and originates first mortgage loans on residential properties primarily located in its market areas. Effective January 16, 2018, the Company completed the Puget Sound Merger and on July 2, 2018, the Company completed the Premier Merger, collectively called the "Premier and Puget Mergers." See Note (2) Business Combinations for additional information on the Premier and Puget Mergers.
Basis of Presentation	Basis of Presentation The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with GAAP for interim financial information and pursuant to the rules and regulations of the SEC. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. It is recommended that these unaudited Condensed Consolidated Financial Statements and accompanying Notes be read with the audited Consolidated Financial Statements and the accompanying Notes included in the 2018 Annual Form 10-K. In management's opinion, all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair presentation have been included. Operating results for the three and nine months ended September 30, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019 . In preparing the unaudited Condensed Consolidated Financial Statements, management is required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosures. Management believes that the judgments, estimates and assumptions used in the preparation of the financial statements are appropriate based on the facts and circumstances at the time. Actual results, however, could differ significantly from those estimates.
Operating Leases Policy	Operating leases During the normal course of business, the Company enters into agreements, and at inception it determines if a particular agreement is a lease. The Company's noncancelable operating lease agreements relate to certain banking offices, back-office operational facilities, office equipment, and sublease agreements. The agreements are recorded as ROU assets and liabilities within prepaid expenses and other assets and accrued expenses and other liabilities, respectively, in the Condensed Consolidated Statements of Financial Condition. Operating lease ROU assets and lease liabilities are recognized at the commencement date based on the present value of lease payments over the lease term, and represent the right to use an underlying asset for the lease term and the obligation to make lease payments arising from the lease. As the Company's leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The operating lease ROU asset also includes any lease pre-payments made and excludes lease incentives. The Company's lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The Company elected an exclusion policy for ROU assets and liabilities for operating leases with a term of twelve months or less and a capitalization threshold policy for total contractual lease payments of $25,000 or more. The Company does not account for any leases at a portfolio level.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements FASB ASU 2016-02 , Leases (Topic 842), as amended by ASU 2017-13, 2018-01, 2018-10, ASU 2018-11, and ASU 2019-01 was originally issued in February 2016, to increase transparency and comparability of leases among organizations and to disclose key information about leasing arrangements. The ASU sets out the principles for the recognition, measurement, presentation and disclosure of leases for both lessees and lessors. The Company adopted the ASU on January 1, 2019 and elected the package of practical expedients permitted under the transition guidance within the new standard, which allowed the Company to carry forward the historical determination of contracts as leases, to carry forward lease classifications, and to not reassess initial direct costs for historical lease arrangements. The adoption of this ASU resulted in the initial recognition of operating lease ROU assets and liabilities of approximately $29.2 million and $29.8 million , respectively, in prepaid expenses and other assets and accrued expenses and other liabilities in the Condensed Consolidated Statements of Financial Condition. This change also resulted in a cumulative-effect adjustment to beginning retained earnings of $399,000 , net of tax, under the modified retrospective approach. As a result of electing this transition method, prior periods have not been restated. FASB ASU 2016-13 , Financial Instruments: Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , as amended by ASU 2018-19, ASU 2019-04 and ASU 2019-05, was originally issued in June 2016. Commonly referred to as CECL, this ASU requires financial assets measured at amortized cost basis to be presented at the net amount expected to be collected. For public business entities, this ASU is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years with early adoption permitted for fiscal years after December 15, 2018. The Company is anticipating adopting the Update on January 1, 2020. Upon adoption, the Company expects a change in the processes, internal controls and procedures to calculate the allowance for loan losses, including changes in assumptions and estimates to consider expected credit losses over the life of the loan versus the current accounting practice that utilizes the incurred loss model. In addition, the current accounting policy and procedures for other-than-temporary impairment on investment securities available for sale will be replaced with an allowance approach. The new guidance may result in an increase in the allowance for loan losses which will also reflect the new requirement to include the nonaccretable principal differences on PCI loans; however, the Company is still in the process of determining the magnitude of the increase and its impact on the Condensed Consolidated Financial Statements. During 2017, the Company's management created a CECL steering committee to develop and implement processes and procedures to ensure it is fully compliant with the amendments at the adoption date. In late 2017 the CECL steering committee selected a vendor to assist the Company in the adoption of a model, completed the implementation discovery sessions, and selected an appropriate methodology. During 2019, the Company compiled historical loan data and finalized data queries from the core system for current periods. Management is finalizing assumptions used in the model and running and analyzing CECL ALLL outcomes. The Company anticipates providing an estimated ALLL under the CECL model in January 2020. FASB ASU 2017-04 , Goodwill (Topic 350) , was issued in January 2017 and eliminates Step 2 from the goodwill impairment test. The ASU is effective for annual periods or any interim goodwill impairment tests beginning after December 15, 2019 using a prospective transition method and early adoption is permitted. The Company does not expect the ASU will have a material impact on its Condensed Consolidated Financial Statements. FASB ASU 2018-13 , Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement, was issued in August 2018 and modifies the disclosure requirements on fair value measurements in Topic 820. The amendments in this ASU are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The Company does not expect the ASU will have a material impact on its Condensed Consolidated Financial Statements.

Financing Receivables [Text Block]	Loans Receivable (a) Loan Origination/Risk Management The Company originates loans in the ordinary course of business and has also acquired loans through mergers and acquisitions. Disclosures related to the Company's recorded investment in loans receivable generally exclude accrued interest receivable and net deferred fees or costs as they were deemed insignificant. Loans acquired in a business combination are further classified as “purchased” loans. Loans purchased with evidence of credit deterioration since origination for which it is probable that not all contractually required payments will be collected are accounted for under FASB ASC 310-30, Receivables —Loans and Debt Securities Acquired with Deteriorated Credit Quality . These loans are identified as "PCI" loans. Loans purchased that are not accounted for under FASB ASC 310-30 are accounted for under FASB ASC 310-20, Receivables—Nonrefundable Fees and Other Costs, and are referred to as "non-PCI" loans. There were no PCI loans acquired in the Premier and Puget Mergers. The Company categorizes loans in one of the four segments of the total loan portfolio: commercial business, one-to-four family residential, real estate construction and land development and consumer. Within these segments are classes of loans for which management monitors and assesses credit risk in the loan portfolios. Loans receivable at September 30, 2019 and December 31, 2018 consisted of the following portfolio segments and classes: September 30, 2019 December 31, 2018 (In thousands) Commercial business: Commercial and industrial $ 853,995 $ 853,606 Owner-occupied commercial real estate 787,591 779,814 Non-owner occupied commercial real estate 1,316,992 1,304,463 Total commercial business 2,958,578 2,937,883 One-to-four family residential 121,174 101,763 Real estate construction and land development: One-to-four family residential 98,034 102,730 Five or more family residential and commercial properties 147,686 112,730 Total real estate construction and land development 245,720 215,460 Consumer 403,485 395,545 Gross loans receivable 3,728,957 3,650,651 Net deferred loan costs 2,386 3,509 Loans receivable, net 3,731,343 3,654,160 Allowance for loan losses (36,518 ) (35,042 ) Total loans receivable, net $ 3,694,825 $ 3,619,118 (b) Concentrations of Credit As of September 30, 2019 , and December 31, 2018 , there were no concentrations of loans related to any single industry in excess of 10% of the Company’s total loans. (c) Credit Quality Indicators As part of the on-going monitoring of the credit quality of the Company’s loan portfolio, management tracks certain credit quality indicators including trends related to (i) the risk grade of the loans, (ii) the level of classified loans, (iii) net charge-offs, (iv) nonperforming loans and (v) the general economic conditions of the United States of America, and specifically the states of Washington and Oregon. The Company utilizes a risk grading matrix to assign a risk grade to each loan on a scale of 1 to 10. Risk grades are aggregated to create the risk categories of "Pass" for grades 1 to 6, OAEM for grade 7, "Substandard" for grade 8, "Doubtful" for grade 9 and "Loss" for grade 10.

Potential problem loans may include PCI loans as these loans continue to accrete loan discounts established at acquisition based on the guidance of FASB ASC 310-30. Potential problem loans as of September 30, 2019 and December 31, 2018 were $85.3 million and $101.3 million , respectively.

Loans that were modified as TDR loans during the three and nine months ended September 30, 2019 and 2018 are set forth in the following tables: Three Months Ended September 30, 2019 2018 Number of Recorded Investment (1) Number of Recorded Investment (1) (Dollars in thousands) Commercial business: Commercial and industrial 15 $ 5,266 11 $ 2,352 Owner-occupied commercial real estate 2 1,214 2 1,081 Non-owner occupied commercial real estate 3 2,597 2 2,776 Total commercial business 20 9,077 15 6,209 Consumer 3 26 1 25 Total loans modified as TDR loans 23 $ 9,103 16 $ 6,234 Nine Months Ended September 30, 2019 2018 Number of (2) Recorded Investment (1,2) Number of Contracts (2) Recorded Investment (1,2) (Dollars in thousands) Commercial business: Commercial and industrial 33 $ 22,414 22 $ 4,445 Owner-occupied commercial real estate 3 1,612 3 1,639 Non-owner occupied commercial real estate 4 5,568 3 2,976 Total commercial business 40 29,594 28 9,060 Real estate construction and land development: One-to-four family residential 1 560 2 767 Consumer 10 155 8 133 Total TDR loans 51 $ 30,309 38 $ 9,960 (1) Includes subsequent payments after modifications and reflects the balance as of period end. As the Bank did not forgive any principal or interest balance as part of the loan modification, the Bank’s recorded investment in each loan at the date of modification (pre-modification) did not change as a result of the modification (post-modification), except when the modification was the initial advance on a one-to-four family residential real estate construction and land development loan under a master guidance line. There were no advances on these types of loans during the three and nine months ended September 30, 2019 and 2018 . (2) Number of contracts and outstanding principal balance represent loans which have balances as of period end as certain loans may have been paid-down or charged-off during the nine months ended September 30, 2019 and 2018 . The tables above include seven and 17 loans, respectively, for the three and nine months ended September 30, 2019 and nine and 15 loans, respectively, for the three and nine months ended September 30, 2018 that were previously reported as TDR loans. The Bank typically grants shorter extension periods to continually monitor these TDR loans despite the fact that the extended date might not be the date the Bank expects sufficient cash flow from these borrowers. The Bank does not consider these modifications a subsequent default of a TDR as new loan terms, specifically new maturity dates, were granted. Of the remaining first-reported TDR loans, the concessions granted largely consisted of maturity extensions, interest rate modifications or a combination of both. The potential losses related to TDR loans are considered in the period the loan was first reported as a TDR loan and are adjusted, as necessary, in the current period based on more recent information. The related specific valuation allowance at September 30, 2019 for loans that were modified as TDR loans during the nine months ended September 30, 2019 was $1.8 million .

The Bank has chosen not to extend further the maturity date on these loans. In addition, during both the three and nine months ended September 30, 2019 , two TDR loans defaulted because the borrowers were more than 90 days delinquent on their scheduled loan payments. The Bank had a specific valuation allowance of $412,000 at September 30, 2019 related to these TDR loans which defaulted during the nine months ended September 30, 2019 . During the three and nine months ended September 30, 2018 , two and three TDR loans, respectively, defaulted because each was past its modified maturity date, and the borrower has not subsequently repaid the credits.
