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 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 headquartered in Olympia, Washington and conducts business from its 53 branch offices as of March 31, 2021 located throughout Washington State and the greater Portland, Oregon area. The Bank’s business consists primarily of commercial lending and deposit relationships with small and medium-sized 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. The Bank's deposits are insured by the FDIC. (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 2020 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 months ended March 31, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021. To prepare unaudited Condensed Consolidated Financial Statements in conformity with GAAP, management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided. Management believes that the judgments, estimates, and assumptions used in the preparation of the Condensed Consolidated Financial Statements are appropriate based on the facts and circumstances at the time. Actual results, however, could differ significantly from those estimates. Material estimates that are particularly susceptible to significant change relate to management's estimate of ACL on loans, management's estimate of ACL on unfunded commitments, management's evaluation of goodwill impairment and the fair value of financial instruments. It is reasonably possible that management's estimate of the ACL on loans of $64.2 million at March 31, 2021 as disclosed in Note (4) Allowance for Credit Losses on Loans, management's estimate of the ACL on unfunded commitments of $3.6 million as disclosed in Note (14) Commitments and Contingencies, management's conclusion that the fair value of the reporting unit more likely than not exceeds its carrying value at March 31, 2021 as disclosed in Note (6) Goodwill and Other Intangible Assets and the estimates of fair value of financial instruments as disclosed in Note (12) Fair Value Measurements could materially change. In particular, these estimates have been and will continue to be affected by the ongoing COVID-19 pandemic. The severity, magnitude and duration, as well as the economic consequences of the COVID-19 pandemic, are uncertain, rapidly changing and difficult to predict. As a result, our accounting estimates and assumptions may change over time in response to the COVID-19 pandemic. The accompanying Condensed Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiary, the Bank. All significant intercompany balances and transactions among the Company and the Bank have been eliminated in consolidation. Certain prior year amounts in the Condensed Consolidated Statements of Income and the Condensed Consolidated Statements of Cash Flows have been reclassified to conform to the current year’s presentation. Reclassifications had no effect on the prior years' net income or stockholders’ equity. (c) Significant Accounting Policies The significant accounting policies used in preparation of the Condensed Consolidated Financial Statements are disclosed in greater detail in the 2020 Annual Form 10-K. There have not been any material changes in the Company's significant accounting policies from those contained in the 2020 Annual Form 10-K during the three months ended March 31, 2021. (d) Recently Issued or Adopted Accounting Pronouncements 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, ASU 2019-05, ASU 2019-10, ASU 2019-11, and ASU 2020-02, was originally issued in June 2016. This ASU replaced the incurred loss methodology with an expected loss methodology, which is commonly referred to as the "CECL" methodology. The measurement of expected credit losses under the CECL methodology is applicable to financial assets measured at amortized cost, including loans receivable. It also applies to off-balance sheet credit exposures such as loan commitments, standby letters of credit, financial guarantees, and other similar instruments. In addition, CECL Adoption made changes to the accounting for credit losses on investment securities available for sale. 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 and can be delayed under a provision of the CARES Act until the end of the official health emergency declaration. The Bank adopted ASU 2016-13 using the modified retrospective method for all financial assets measured at amortized cost and unfunded commitments. At adoption, the Bank elected not to measure an ACL on accrued interest receivable on loans receivable or accrued interest receivable on investment securities available for sale as Bank policy is to reverse interest income for uncollectible accrued interest receivable balances in a timely manner. The adoption of ASU 2016-13 included an increase to the ACL on loans of $3.4 million and an increase to the ACL on unfunded commitments of $3.7 million, resulting in a pretax cumulative-effect adjustment of $7.1 million. The impact of this adjustment to beginning retained earnings on January 1, 2020 was $5.6 million, net of tax. FASB ASU 2020-04 , Reference Rate Reform (Topic 848) , as amended by ASU 2021-01, was issued in March 2020 and provides optional expedients and exceptions for applying GAAP to loan and lease agreements, derivative contracts, and other transactions affected by the anticipated transition away from LIBOR toward new interest rate benchmarks. For transactions that are modified because of reference rate reform and that meet certain scope guidance (i) modifications of loan agreements should be accounted for by prospectively adjusting the effective interest rate and the modification will be considered "minor" so that any existing unamortized origination fees/costs would carry forward and continue to be amortized and (ii) modifications of lease agreements should be accounted for as a continuation of the existing agreement with no reassessments of the lease classification and the discount rate or remeasurements of lease payments that otherwise would be required for modifications not accounted for as separate contracts. ASU 2020-04 also provides numerous optional expedients for derivative accounting and is effective March 12, 2020 through December 31, 2022. An entity may elect to apply the ASU for contract modifications as of January 1, 2020, or prospectively from a date within an interim period that includes or is subsequent to March 12, 2020, up to the date that the financial statements are available to be issued. Once elected for a Topic or an Industry Subtopic within the Codification, the amendments in this ASU must be applied prospectively for all eligible contract modifications for that Topic or Industry Subtopic. The Bank’s swap related transactions are the majority of the Company's LIBOR exposure. Effective January 25, 2021, the Company has agreed to adhere to the Interbank Offered Rate Fallbacks Protocol as published by the International Swaps and Derivatives Association, Inc. and recommended by the Alternative Reference Rates Committee. The Company further anticipates this ASU will simplify any modifications executed between the selected start date (yet to be determined) and December 31, 2022 that are directly related to LIBOR transition by allowing prospective recognition of the continuation of the contract, rather than extinguishment of the old contract resulting in writing off unamortized net deferred fees. The Company does not expect this ASU to have a material impact on its business operations and the Condensed Consolidated Financial Statements.

Management monitors published credit ratings for adverse changes for all rated investment securities and none of these securities had a below investment grade credit rating as of both March 31, 2021 and December 31, 2020. In addition, the Company does not intend to sell these securities nor does the Company consider it more likely than not that it will be required to sell these securities before the recovery of the amortized cost basis, which may be upon maturity. Therefore, no ACL on investment securities available for sale was recorded as of March 31, 2021 and December 31, 2020.

Loans and Leases Receivable Disclosure [Abstract]
Loans Receivable	Loans Receivable (a) Loan Origination/Risk Management The Bank originates loans in the ordinary course of business and has also acquired loans through mergers and acquisitions. Accrued interest receivable was excluded from disclosures presenting the Bank's amortized cost of loans receivable as it was deemed insignificant. The Bank categorizes the individual loans in the total loan portfolio into four segments: commercial business; residential real estate; 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. A detailed description of the portfolio segments and classes is contained in the 2020 Annual Form 10-K. The amortized cost of loans receivable, net of ACL on loans at March 31, 2021 and December 31, 2020 consisted of the following portfolio segments and classes: March 31, December 31, (In thousands) Commercial business: Commercial and industrial $ 693,539 $ 733,098 SBA PPP 886,761 715,121 Owner-occupied CRE 881,168 856,684 Non-owner occupied CRE 1,427,953 1,410,303 Total commercial business 3,889,421 3,715,206 Residential real estate 114,856 122,756 Real estate construction and land development: Residential 79,878 78,259 Commercial and multifamily 217,815 227,454 Total real estate construction and land development 297,693 305,713 Consumer 293,899 324,972 Loans receivable 4,595,869 4,468,647 Allowance for credit losses on loans (64,225) (70,185) Loans receivable, net $ 4,531,644 $ 4,398,462 Balances included in the amortized cost of Loans receivable: Unamortized net discount on acquired loans $ (5,501) $ (6,575) Unamortized net deferred fee $ (24,017) $ (15,458) (b) Concentrations of Credit Most of the Bank’s lending activity occurs within its primary market areas which are concentrated along the I-5 corridor from Whatcom County to Clark County in Washington State and Multnomah County and Washington County in Oregon, as well as other contiguous markets and represents a geographic concentration. Additionally, our loan portfolio is concentrated in commercial-type loans, including commercial business loans and commercial and multifamily real estate construction and land development loans. (c) Credit Quality Indicators As part of the on-going monitoring of the credit quality of the Bank’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, (v) past due status and (vi) the general economic conditions of the United States of America, and specifically the states of Washington and Oregon. The Bank utilizes a risk grading matrix to assign a risk grade to each of its loans. Loans are graded on a scale of 1 to 10. Risk grades are aggregated to create the risk categories of Pass for grades 1 to 6, Special Mention or "SM" for grade 7, Substandard or "SS" for grade 8, Doubtful for grade 9 and Loss for grade 10. Descriptions of the general characteristics of the risk grades, including qualitative information on how the risk grades relate to the risk of loss, are contained in the 2020 Annual Form 10-K. Numerical loan grades for loans are established at the origination of the loan. Changes to loan grades are considered at the time new information about the performance of a loan becomes available, including the receipt of updated financial information from the borrower, results of annual term loan reviews performed by the Bank's Credit department and scheduled loan reviews performed by the Bank’s Loan Review department. For consumer loans, the Bank follows the FDIC’s Uniform Retail Credit Classification and Account Management Policy for subsequent classification in the event of payment delinquencies or default. Typically, an individual loan grade will not be changed from the prior period unless there is a specific indication of credit deterioration or improvement. Credit deterioration is evidenced by delinquency, direct communications with the borrower, or other borrower information that becomes known to management. Credit improvements are evidenced by known facts regarding the borrower or the collateral property. Loan grades relate to the likelihood of losses in that the higher the grade, the greater the loss potential. Loans with a pass grade may have some estimated inherent losses, but to a lesser extent than the other loan grades. The SM loan grade is transitory in that the Bank is waiting on additional information to determine the likelihood and extent of the potential loss. The likelihood of loss for SM graded loans, however, is greater than Watch graded loans because there has been measurable credit deterioration. Loans with a SS grade are generally loans with higher risk of loss if the deficiencies are not corrected. For Doubtful and Loss graded loans, the Bank is almost certain of the losses and the outstanding principal balances are generally charged off to the realizable value. Regulatory agencies provided guidance regarding credit risk ratings, delinquency reporting and nonaccrual status for loans adversely impacted by COVID-19. The Bank has and will continue to exercise judgment in determining the risk rating for impacted borrowers and will not automatically adversely classify credits that are affected by COVID-19. The Bank also will not designate loans with payment deferrals granted due to COVID-19 as past due because of the deferral. Due to the short-term nature of the forbearance and other relief programs we are offering as a result of the COVID-19 pandemic, we expect that borrowers granted relief under these programs will generally not be reported as nonaccrual during the deferral period.

There have been no significant changes to the collateral securing individually evaluated loans for credit losses and for which repayment was expected to be provided substantially through the operation or sale of the collateral during the three months ended March 31, 2021, except changes due to payoffs and additions of loans to this classification. (g) Troubled Debt Restructured Loans The majority of the Bank’s TDR loans are a result of granting extensions of maturity on troubled credits which have already been adversely classified. The Bank grants such extensions to reassess the borrower’s financial status and to develop a plan for repayment. The second most prevalent concession was the result of COVID Modifications, including payment deferrals and maturity extensions. The Bank has also accommodated re-amortizing loans over a longer period of time. Each of these modifications were a concession for a borrower that could not obtain similar financing terms from another source other than from the Bank. The financial effects of each modification will vary based on the specific restructure. The Bank has a policy that it does not forgive principal or accrued interest as modified terms. The Bank’s TDR loans are primarily fully amortizing term loans. If the interest rate is not adjusted and the modified terms are consistent with other similar credits being offered, the Bank may not experience any loss associated with the restructure. If, however, the restructure involves interest rate modifications, the Bank may not collect all interest based on the original contractual terms. The CARES Act, CA Act and regulatory agencies provided guidance around the modification of loans as a result of the COVID-19 pandemic, and outlined, among other criteria, that short-term modifications made on a good faith basis to borrowers who were current as defined by the guidance are not TDRs. This includes short-term (e.g. six months) modifications such as payment deferrals, fee waivers, extensions of repayment terms, or other delays in payment that are insignificant. Borrowers were considered current if they were less than 30 days past due on the contractual payments as of December 31, 2019 under the CARES Act and at the time a modification program is implemented under related regulatory guidance. The CA Act extended relief offered under the CARES Act through January 1, 2022 or 60 days after the end of the national emergency declared by the President, whichever is earlier. The Bank elected to apply the temporary relief under the applicable guidance to certain eligible short-term modifications and did not classify the modifications as TDRs for accounting or disclosure purposes. However, COVID Modifications whose payment deferral exceeded 180 days following the loans' initial modification were classified as TDRs based on the Bank's internal policy. The unfunded commitment to borrowers related to TDR loans was $5.0 million and $2.6 million at March 31, 2021 and December 31, 2020, respectively. For the three months ended March 31, 2021 and March 31, 2020 , the Bank recorded $1.8 million and $608,000 , respectively, of interest income related to performing TDR loans. Loans that were modified as TDR loans are set forth in the following table for the periods indicated: Three Months Ended March 31, 2021 2020 Number of Amortized Cost (1) (2) Number of Amortized Cost (1) (2) (Dollars in thousands) Commercial business: Commercial and industrial 24 $ 12,102 13 $ 3,688 Owner-occupied CRE 2 4,660 4 2,183 Non-owner occupied CRE 1 1,979 3 2,210 Total commercial business 27 18,741 20 8,081 Residential real estate 1 180 — — Real estate construction and land development: Residential — — 4 1,516 Commercial and multifamily 1 450 — — Total real estate construction and land development 1 450 4 1,516 Consumer 15 379 5 93 Total 44 $ 19,750 29 $ 9,690 (1) Number of contracts and amortized cost represent loans which have balances as of period end, net of subsequent payments after modifications. Certain modified loans may have been paid-down or charged-off during the three months ended March 31, 2021 and March 31, 2020. (2) As the Bank did not forgive any principal or interest balance as part of the loan modifications, the Bank’s amortized cost in each loan at the date of modification (pre-modification) did not change as a result of the modification (post-modification). The table above includes 19 and 11 loans for th e three months ended March 31, 2021 and 2020, respectively, 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. The Bank had a related ACL on loans that were modified as TDR lo ans of $2.4 million an d $644,000 at March 31, 2021 and March 31, 2020, respectively. The following table presents loans that were modified in a troubled debt restructure and subsequently defaulted within twelve months from the modification date during the periods indicated: Three Months Ended March 31, 2021 2020 Number of Contracts (1) Amortized Cost (1) Number of Contracts (1) Amortized Cost (1) (Dollars in thousands) Commercial business: Commercial and industrial 2 $ 2,792 2 $ 1,873 Non-owner occupied CRE — — 3 590 Total commercial business 2 2,792 5 2,463 Total 2 $ 2,792 5 $ 2,463 (1) Number of contracts and amortized cost represent loans which have balances as of period end, net of subsequent payments after modifications. Certain modified loans may have been paid-down or charged-off during the three months ended March 31, 2021 and March 31, 2020. During the three months ended March 31, 2021 and March 31, 2020 these TDR loans defaulted because each was past its modified maturity date and the borrower had not subsequently repaid the credits. The Bank chose not to extend further the maturity date on these loans. The Bank had an ACL on loans of $94,000 and $334,000 at March 31, 2021 and March 31, 2020, respectively, related to these TDR loans which defaulted during the three months ended March 31, 2021. (h) Accrued interest receivable on loans receivable Accrued interest receivable on loans receivable totaled $16.0 million and $15.8 million at March 31, 2021 and December 31, 2020, respectively. It is excluded from the calculation of the ACL on loans as interest accrued, but not received, is reversed timely. However, management completed an analysis for an ACL on accrued interest receivable on loans receivable based on the significance of loan modifications in accordance with the CARES Act, CA Act and regulatory guidance and concluded no ACL on accrued interest receivable on loans should be recorded at March 31, 2021 and December 31, 2020.

Allowance for Loan Losses

Allowance for Loan Losses	3 Months Ended

Receivables [Abstract]
Allowance for Loan Losses	Allowance for Credit Losses on Loans Effective January 1, 2020, the Bank adopted ASU 2016-13. Risk characteristics by segment considered in the CECL model are the same as those disclosed in the 2020 Annual Form 10-K. The baseline loss rates used to calculate the ACL on loans at March 31, 2021 utilized the Bank's average quarterly historical loss information from December 31, 2012 through the balance sheet date. There were no changes to this assumption during the three months ended March 31, 2021. The Bank believes the historic loss rates are viable inputs to the current CECL model as the Bank's lending practice and business has remained relatively stable throughout the periods. While the Bank's assets have grown, the credit culture has stayed relatively consistent. Prepayments included in the CECL model at March 31, 2021 were based on the 48-month rolling historical averages for each segment, which management believes is an accurate representation of future prepayment activity. There were no changes to this assumption during the three months ended March 31, 2021. The reasonable and supportable period used in the CECL model as of March 31, 2021 was five quarters. There were no changes to this assumption during the three months ended March 31, 2021. Management believes that forecasts beyond this five quarter time period tend to diverge in economic assumptions and may be less comparable to actual future events. As the length of the reasonable and supportable period increases, the degree of judgment involved in estimating the allowance will likely increase. The Bank used a two-quarter reversion period in calculating the ACL on loans as of March 31, 2021 as it believes the historical loss information is relevant to the expected credit losses and recognizes the declining precision and increasing uncertainty of estimating credit losses in those periods beyond which it can make reasonable and supportable forecasts. There were no changes to this assumption during the three months ended March 31, 2021. During the three months ended March 31, 2021, the ACL on loans decreased $6.0 million, or 8.5%, due primarily to a reversal of provision for credit losses on loans of $6.1 million following improvements in the economic forecast at March 31, 2021 as compared to the forecast for the three months ended December 31, 2020 and secondarily due to a decrease in total loans receivable, excluding SBA PPP which are fully guaranteed by the SBA and not provisioned for in the ACL on loans. A summary of the changes in the ACL on loans during the three months ended March 31, 2021 and 2020 is as follows: Three Months Ended March 31, 2021 2020 (In thousands) Balance at the beginning of the year $ 70,185 $ 36,171 Impact of CECL Adoption — 1,822 Balance at the beginning of the year, as adjusted 70,185 37,993 Charge-offs (187) (1,597) Recoveries of loans previously charged-off 362 1,180 (Reversal of) provision for loan losses (6,135) 9,964 Balance at the end of the year $ 64,225 $ 47,540 The following tables detail the activity in the ACL on loans disaggregated by segment and class for the three months ended March 31, 2021 and 2020: Three Months Ended March 31, 2021 Beginning Balance Charge-offs Recoveries (Reversal of) Provision for Credit Losses Ending Balance (In thousands) Commercial business: Commercial and industrial $ 30,010 $ (1) $ 205 $ (8,444) $ 21,770 SBA PPP — — — — — Owner-occupied CRE 9,486 — 2 976 10,464 Non-owner occupied CRE 10,112 — — 2,858 12,970 Total commercial business 49,608 (1) 207 (4,610) 45,204 Residential real estate 1,591 — — (189) 1,402 Real estate construction and land development: Residential 1,951 — 16 81 2,048 Commercial and multifamily 11,141 (1) — 83 11,223 Total real estate construction and land development 13,092 (1) 16 164 13,271 Consumer 5,894 (185) 139 (1,500) 4,348 Total $ 70,185 $ (187) $ 362 $ (6,135) $ 64,225 Three Months Ended March 31, 2020 Beginning Balance Impact of CECL Adoption Beginning Balance, Charge-offs Recoveries (Reversal of) Provision for Credit Losses Ending Balance (In thousands) Commercial business: Commercial and industrial $ 11,739 $ (1,348) $ 10,391 $ (1,087) $ 1,057 $ 3,539 $ 13,900 SBA PPP — — — — — — — Owner-occupied CRE 4,512 452 4,964 (135) 12 1,375 6,216 Non-owner occupied CRE 7,682 (2,039) 5,643 — — 2,107 7,750 Total commercial business 23,933 (2,935) 20,998 (1,222) 1,069 7,021 27,866 Residential real estate 1,458 1,471 2,929 — 3 94 3,026 Three Months Ended March 31, 2020 Beginning Balance Impact of CECL Adoption Beginning Balance, Charge-offs Recoveries (Reversal of) Provision for Credit Losses Ending Balance (In thousands) Real estate construction and land development: Residential 1,455 (571) 884 — 14 (34) 864 Commercial and multifamily 1,605 7,240 8,845 — — 2,599 11,444 Total real estate construction and land development 3,060 6,669 9,729 — 14 2,565 12,308 Consumer 6,821 (2,484) 4,337 (375) 94 284 4,340 Unallocated 899 (899) — — — — — Total $ 36,171 $ 1,822 $ 37,993 $ (1,597) $ 1,180 $ 9,964 $ 47,540

Stockholders' Equity	Stockholders’ Equity (a) Earnings Per Common Share The following table illustrates the calculation of weighted average shares used for earnings per common share computations at March 31, 2021 and March 31, 2020: Three Months Ended 2021 2020 (In thousands, except shares) Net income: Net income $ 25,344 $ 12,191 Dividends and undistributed earnings allocated to participating securities (1) — (6) Net income allocated to common shareholders $ 25,344 $ 12,185 Basic: Weighted average common shares outstanding 35,926,950 36,357,812 Restricted stock awards — (15,722) Total basic weighted average common shares outstanding 35,926,950 36,342,090 Diluted: Basic weighted average common shares outstanding 35,926,950 36,342,090 Effect of potentially dilutive common shares (2) 305,254 254,551 Total diluted weighted average common shares outstanding 36,232,204 36,596,641 Potentially dilutive shares that were excluded from the computation of diluted earnings per share because to do so would be anti-dilutive (3) 15,538 21,475 (1) Represents dividends paid and undistributed earnings allocated to unvested restricted stock awards. (2) Represents the effect of the assumed exercise of stock options and vesting of restricted stock awards and units. (3) 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. (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 during the three months ended March 31, 2021 and the calendar year 2020: Declared Cash Dividend per Share Record Date Paid Date January 22, 2020 $0.20 February 6, 2020 February 20, 2020 April 29, 2020 $0.20 May 13, 2020 May 27, 2020 July 22, 2020 $0.20 August 5, 2020 August 19, 2020 October 21, 2020 $0.20 November 4, 2020 November 18, 2020 January 27, 2021 $0.20 February 10, 2021 February 24, 2021 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. On March 12, 2020 the Company's Board of Directors additionally authorized the repurchase of up to 5% of the Company's outstanding common shares, or 1,799,054 shares, under the twelfth stock repurchase plan after all shares under the eleventh stock repurchase plan had been repurchased. The number, timing and price of shares repurchased under the twelfth stock repurchase plan will depend on business and market conditions and other factors, including opportunities to deploy the Company's capital. The following table provides total repurchased shares and average share prices under the applicable plans for the periods indicated: Three Months Ended 2021 2020 Plan Total (1) Eleventh Stock Repurchase Plan Repurchased shares — 639,922 1,512,600 Stock repurchase average share price $ — $ 23.95 $ 21.69 Twelfth Stock Repurchase Plan Repurchased shares — 155,778 155,778 Stock repurchase average share price $ — $ 20.34 $ 20.34 (1) Represents shares repurchased and average price per share paid during the duration of each plan. In addition to the stock repurchases under a stock repurchase plan, the Company repurchases shares to pay withholding taxes on the vesting of restricted stock awards and units.

Fair Value Measurements

Fair Value Measurements	3 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Fair value is the price that would be received to sell 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 at 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. Collateral-Dependent Loans : Collateral-dependent loans are identified as part of the calculation of the ACL on loans. The fair value used to measure credit loss for this type of loan is commonly based on recent real estate appraisals which are generally obtained at least every 18 months or earlier if there are changes to risk characteristics of the underlying loan. 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. The Bank also incorporates an estimate of cost to sell the collateral when the sale is probable. Such adjustments may be significant and 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 customer and customer’s business (Level 3). Individually evaluated loans are analyzed for credit loss on a quarterly basis and the ACL on loans is adjusted as required based on the results. Appraisals on collateral-dependent loans 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 Bank. Once received, the Bank 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. Derivative Financial Instruments: The Bank 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), and incorporates credit valuation adjustments to reflect nonperformance risk in the measurement of fair value (Level 3). Although the Bank has determined that the majority of the inputs used to value its interest rate swap derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as borrower risk ratings, to evaluate the likelihood of default by itself and its counterparties. As of March 31, 2021 and December 31, 2020, the Bank assessed the significance of the impact of the credit valuation adjustment on the overall valuation of its interest rate swap derivatives and determined that the credit valuation adjustment was not significant to the overall valuation of its interest rate swap derivatives. As a result, the Bank has classified its interest rate swap derivative valuations in Level 2 of the fair value hierarchy. Branches held for sale : Branches held for sale are recorded at fair value less costs to sell when transferred from Premises and equipment, net to Prepaid expenses and other assets on the Consolidated Statements of Financial Condition with any valuation adjustment recorded within Other noninterest expense on the Consolidated Statements of Income. The fair value of branches held for sale is determined based on a real estate appraisal or broker price opinion. Adjustments are routinely made in the appraisal and broker price opinion process by independent appraisers and commercial real estate brokers, respectively, 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.

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.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies In the ordinary course of business, the Bank may enter into various types of transactions that include commitments to extend credit that are not included in its Condensed Consolidated Financial Statements. The Bank applies the same credit standards to these commitments as it uses in all its lending activities and has included these commitments in its lending risk evaluations. The majority of the commitments presented below are variable rate. Loan commitments can be either revolving or non-revolving. The Bank’s exposure to credit and market risk under commitments to extend credit is represented by the amount of these commitments. The following table presents outstanding commitments to extend credit, including letters of credit, at the dates indicated: March 31, 2021 December 31, 2020 (In thousands) Commercial business: Commercial and industrial $ 627,702 $ 640,018 Owner-occupied CRE 4,494 3,488 Non-owner occupied CRE 14,523 18,396 Total commercial business 646,719 661,902 Real estate construction and land development: Residential 60,099 52,453 Commercial and multifamily 142,432 127,821 Total real estate construction and land development 202,531 180,274 Consumer 269,516 263,249 Total outstanding commitments $ 1,118,766 $ 1,105,425 Upon CECL adoption, as described in Note (1) Description of Business, Basis of Presentation, Significant Accounting Policies and Recently Issued Accounting Pronouncements, the Bank recorded an increase in the beginning ACL on unfunded commitments of $3.7 million as of January 1, 2020, representing the change in methodology from an estimate of incurred losses at the balance sheet date, with an estimated probability of funding, to an estimate of credit losses on future utilization over the entire contractual period.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business	Description of BusinessThe 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 headquartered in Olympia, Washington and conducts business from its 53 branch offices as of March 31, 2021 located throughout Washington State and the greater Portland, Oregon area. The Bank’s business consists primarily of commercial lending and deposit relationships with small and medium-sized 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. The Bank's deposits are insured by the FDIC.
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 2020 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 months ended March 31, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021. To prepare unaudited Condensed Consolidated Financial Statements in conformity with GAAP, management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided. Management believes that the judgments, estimates, and assumptions used in the preparation of the Condensed Consolidated Financial Statements are appropriate based on the facts and circumstances at the time. Actual results, however, could differ significantly from those estimates. Material estimates that are particularly susceptible to significant change relate to management's estimate of ACL on loans, management's estimate of ACL on unfunded commitments, management's evaluation of goodwill impairment and the fair value of financial instruments. It is reasonably possible that management's estimate of the ACL on loans of $64.2 million at March 31, 2021 as disclosed in Note (4) Allowance for Credit Losses on Loans, management's estimate of the ACL on unfunded commitments of $3.6 million as disclosed in Note (14) Commitments and Contingencies, management's conclusion that the fair value of the reporting unit more likely than not exceeds its carrying value at March 31, 2021 as disclosed in Note (6) Goodwill and Other Intangible Assets and the estimates of fair value of financial instruments as disclosed in Note (12) Fair Value Measurements could materially change. In particular, these estimates have been and will continue to be affected by the ongoing COVID-19 pandemic. The severity, magnitude and duration, as well as the economic consequences of the COVID-19 pandemic, are uncertain, rapidly changing and difficult to predict. As a result, our accounting estimates and assumptions may change over time in response to the COVID-19 pandemic. The accompanying Condensed Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiary, the Bank. All significant intercompany balances and transactions among the Company and the Bank have been eliminated in consolidation. Certain prior year amounts in the Condensed Consolidated Statements of Income and the Condensed Consolidated Statements of Cash Flows have been reclassified to conform to the current year’s presentation. Reclassifications had no effect on the prior years' net income or stockholders’ equity.
Recently Issued Accounting Pronouncements	Recently Issued or Adopted Accounting Pronouncements 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, ASU 2019-05, ASU 2019-10, ASU 2019-11, and ASU 2020-02, was originally issued in June 2016. This ASU replaced the incurred loss methodology with an expected loss methodology, which is commonly referred to as the "CECL" methodology. The measurement of expected credit losses under the CECL methodology is applicable to financial assets measured at amortized cost, including loans receivable. It also applies to off-balance sheet credit exposures such as loan commitments, standby letters of credit, financial guarantees, and other similar instruments. In addition, CECL Adoption made changes to the accounting for credit losses on investment securities available for sale. 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 and can be delayed under a provision of the CARES Act until the end of the official health emergency declaration. The Bank adopted ASU 2016-13 using the modified retrospective method for all financial assets measured at amortized cost and unfunded commitments. At adoption, the Bank elected not to measure an ACL on accrued interest receivable on loans receivable or accrued interest receivable on investment securities available for sale as Bank policy is to reverse interest income for uncollectible accrued interest receivable balances in a timely manner. The adoption of ASU 2016-13 included an increase to the ACL on loans of $3.4 million and an increase to the ACL on unfunded commitments of $3.7 million, resulting in a pretax cumulative-effect adjustment of $7.1 million. The impact of this adjustment to beginning retained earnings on January 1, 2020 was $5.6 million, net of tax. FASB ASU 2020-04 , Reference Rate Reform (Topic 848) , as amended by ASU 2021-01, was issued in March 2020 and provides optional expedients and exceptions for applying GAAP to loan and lease agreements, derivative contracts, and other transactions affected by the anticipated transition away from LIBOR toward new interest rate benchmarks. For transactions that are modified because of reference rate reform and that meet certain scope guidance (i) modifications of loan agreements should be accounted for by prospectively adjusting the effective interest rate and the modification will be considered "minor" so that any existing unamortized origination fees/costs would carry forward and continue to be amortized and (ii) modifications of lease agreements should be accounted for as a continuation of the existing agreement with no reassessments of the lease classification and the discount rate or remeasurements of lease payments that otherwise would be required for modifications not accounted for as separate contracts. ASU 2020-04 also provides numerous optional expedients for derivative accounting and is effective March 12, 2020 through December 31, 2022. An entity may elect to apply the ASU for contract modifications as of January 1, 2020, or prospectively from a date within an interim period that includes or is subsequent to March 12, 2020, up to the date that the financial statements are available to be issued. Once elected for a Topic or an Industry Subtopic within the Codification, the amendments in this ASU must be applied prospectively for all eligible contract modifications for that Topic or Industry Subtopic. The Bank’s swap related transactions are the majority of the Company's LIBOR exposure. Effective January 25, 2021, the Company has agreed to adhere to the Interbank Offered Rate Fallbacks Protocol as published by the International Swaps and Derivatives Association, Inc. and recommended by the Alternative Reference Rates Committee. The Company further anticipates this ASU will simplify any modifications executed between the selected start date (yet to be determined) and December 31, 2022 that are directly related to LIBOR transition by allowing prospective recognition of the continuation of the contract, rather than extinguishment of the old contract resulting in writing off unamortized net deferred fees. The Company does not expect this ASU to have a material impact on its business operations and the Condensed Consolidated Financial Statements.
