Accounting Policies [Abstract]
Description of Business	Description of Business First Financial Northwest, Inc. (“First Financial Northwest”), a Washington corporation, was formed on June 1, 2007 for the purpose of becoming the holding company for First Financial Northwest Bank (the “Bank”) in connection with the conversion from a mutual holding company structure to a stock holding company structure completed on October 9, 2007. First Financial Northwest’s business activities generally are limited to passive investment activities and oversight of its investment in First Financial Northwest Bank. Accordingly, the information presented in the consolidated financial statements and accompanying data, relates primarily to First Financial Northwest Bank. First Financial Northwest is a bank holding company, having converted from a savings and loan holding company on March 31, 2015, and as a bank holding company is subject to regulation by the Federal Reserve Bank of San Francisco. First Financial Northwest Bank is regulated by the Federal Deposit Insurance Corporation (“FDIC”) and the Washington State Department of Financial Institutions (“DFI”). At March 31, 2019, First Financial Northwest Bank operated in eleven locations in Washington with the headquarters and six branch locations in King County and five branch locations in Snohomish County. The Bank’s primary market area consists of King, Snohomish, Pierce and Kitsap counties, Washington. The Bank has received FDIC approval to open an additional branch in Kirkland, Washington, which is expected to open later in 2019. The Bank is a portfolio lender, originating and purchasing one-to-four family residential, multifamily, commercial real estate, construction/land development, business, and consumer loans. Loans are primarily funded by deposits from the general public, supplemented by borrowings from the Federal Home Loan Bank of Des Moines (“FHLB”) and deposits raised in the national brokered deposit market. As used throughout this report, the terms “we,” “our,” “us,” or the “Company” refer to First Financial Northwest, Inc. and its consolidated subsidiary First Financial Northwest Bank, unless the context otherwise requires.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited interim consolidated financial statements have been prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission ("SEC"). Accordingly, they do not include all of the information and footnotes required by U.S. Generally Accepted Accounting Principles (“GAAP”) for complete financial statements. These unaudited interim consolidated financial statements should be read in conjunction with the Company's Annual Report on Form 10-K for the year ended December 31, 2018 , as filed with the SEC (“2018 Form 10-K”). In our opinion, all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair presentation of the unaudited interim consolidated financial statements in accordance with GAAP have been included. All significant intercompany balances and transactions between the Company and its subsidiaries have been eliminated in consolidation. Operating results for the three months ended March 31, 2019 , are not necessarily indicative of the results that may be expected for the year ending December 31, 2019 . In preparing the unaudited consolidated financial statements, we are required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change relate to the allowance for loan and lease losses (“ALLL”), the valuation of other real estate owned (“OREO”) and the underlying collateral of impaired loans, deferred tax assets, the right-of-use asset and lease liability on our operating leases, and the fair value of financial instruments. The Company’s activities are considered to be a single industry segment for financial reporting purposes. The Company is engaged in the business of attracting deposits from the general public and originating and purchasing loans for its portfolio. Substantially all income is derived from a diverse base of commercial, multifamily, and residential real estate loans, consumer lending activities, and investments. Certain amounts in the unaudited interim consolidated financial statements for prior periods have been reclassified to conform to the current unaudited financial statement presentation with no effect on consolidated net income or stockholders’ equity.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements Recent Accounting Pronouncements Adopted in 2019 In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842) . ASU No. 2016-02 requires lessees to recognize on the balance sheet the assets and liabilities arising from operating leases. In July 2018, FASB issued ASU No. 2018-11, Leases (Topic 842) to address the comparative reporting requirements when this ASU is adopted. In March 2019, FASB issued ASU 2019-01, Leases (Topic 842), Codification Improvements. Under these ASUs, a lessee should recognize a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term. A lessee should include payments to be made in an optional period only if the lessee is reasonably certain to exercise an option to extend the lease or not to exercise an option to terminate the lease. For a finance lease, interest payments should be recognized separately from amortization of the right-of-use asset in the statement of comprehensive income. For operating leases, the lease cost should be allocated over the lease term on a generally straight-line basis. The Company adopted this ASU on January 1, 2019 and according to ASU 2018-11, elected to recognize the related cumulative-effect adjustment as an adjustment to the opening balance of retained earnings. Adoption of ASU 2016-02 resulted in the addition of a right-of-use asset and lease related to certain banking offices under noncancelable operating lease agreements. The resulting increase did not to have a material impact on the Company’s consolidated financial statements or regulatory capital ratios. For more information see Note 8 ‑ Leases in this report. In March 2017, FASB issued ASU No. 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities . The ASU shortens the amortization period for certain callable debt securities held at a premium. The Company adopted this ASU during the quarter ended March 31, 2019 with no material impact on the Company's consolidated financial statements. Recent Accounting Pronouncements In June 2016, FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326). This ASU replaces the existing incurred loss impairment methodology that recognizes credit losses when a probable loss has been incurred with new methodology where loss estimates are based upon lifetime expected credit losses. The amendments in this ASU require a financial asset that is measured at amortized cost to be presented at the net amount expected to be collected. The income statement would then reflect the measurement of credit losses for newly recognized financial assets as well as changes to the expected credit losses that have taken place during the reporting period. The measurement of expected credit losses will be based on historical information, current conditions, and reasonable and supportable forecasts that impact the collectability of the reported amount. Available‑for‑sale securities will bifurcate the fair value mark and establish an allowance for credit losses through the income statement for the credit portion of that mark. The interest portion will continue to be recognized through accumulated other comprehensive income or loss. The change in allowance recognized as a result of adoption will occur through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the ASU is adopted. The amendments in this ASU are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, with early adoption permitted for fiscal years beginning after December 15, 2018. The Company is evaluating our current expected loss methodology of our loan and investment portfolios to identify the necessary modifications in accordance with this standard and expects a change in the processes and procedures to calculate the ALLL, 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. A valuation adjustment to our ALLL or investment portfolio that is identified in this process will be reflected as a one-time adjustment in equity rather than earnings. We are in the process of compiling historical and industry data that will be used to calculate expected credit losses on our loan portfolio to ensure we are fully compliant with the ASU at the adoption date and are evaluating the potential impact adoption of this ASU will have on our consolidated financial statements. The Company intends to adopt ASU 2016-13 in the first quarter of 2020, and as a result, we expect our allowance for loan losses to increase. Until our evaluation is complete, however, the magnitude of the increase will not be known. In August 2018, FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820) - Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. The amendments in this ASU remove certain disclosure requirements regarding transfers between Level 1 and Level 2 of the fair value hierarchy and changes in unrealized gains and losses for recurring Level 3 fair value measurements. In addition, the amendments modified and added certain disclosure requirements for Level 3 fair value measurements. This ASU is effective for fiscal years beginning after December 15, 2019, and early adoption is permitted. Entities are permitted to early adopt any removed or modified disclosures and adopt the additional disclosures at the effective date. Adoption of ASU 2018-13 is not expected to have a material impact on the Company’s consolidated financial statements.

The Company considers many factors including the severity and duration of the impairment, recent events specific to the issuer or industry, and for debt securities, external credit ratings and recent downgrades. Securities on which there is an unrealized loss that is deemed to be an other-than-temporary impairment (“OTTI”) are written down to fair value. If the Company intends to sell a debt security, or it is likely that the Company will be required to sell the debt security before recovering its cost basis, the entire impairment loss would be recognized in earnings as an OTTI. If the Company does not intend to sell the debt security and it is not likely that it will be required to sell the debt security but does not expect to recover the entire amortized cost basis of the debt security, only the portion of the impairment loss representing credit losses would be recognized in earnings. The credit loss on a debt security is measured as the difference between the amortized cost basis and the present value of the cash flows expected to be collected. Projected cash flows are discounted by the original or current effective interest rate depending on the nature of the debt security being measured for potential OTTI. The remaining impairment related to all other factors, the difference between the present value of the cash flows expected to be collected and fair value, is recognized as a charge to other comprehensive income (“OCI”). Impairment losses related to all other factors are presented as separate categories within OCI. At March 31, 2019 , and December 31, 2018 , the Company had 37 securities and 51 securities in an unrealized loss position, respectively, with 31 of these securities in an unrealized loss position for 12 months or more at both dates. Management does not believe that any individual unrealized loss as of March 31, 2019 , or December 31, 2018 , represented OTTI. The decline in fair market value of these securities was generally due to changes in interest rates and changes in market-desired spreads subsequent to their purchase. Management also reviewed the financial condition of the entities issuing municipal or corporate bonds at March 31, 2019, and December 31, 2018, and determined that an OTTI charge was not warranted. The amortized cost and estimated fair value of investments available-for-sale at March 31, 2019 , by contractual maturity, are shown below. Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. Investments not due at a single maturity date, primarily mortgage-backed investments, are shown separately.

Investment securities with market values of $15.7 million and $15.6 million were pledged as collateral for public deposits at March 31, 2019 , and December 31, 2018 , respectively, both of which exceeded the collateral requirements established by the Washington Public Deposit Protection Commission. For the three months ended March 31, 2019 , we had calls and sales on investment securities of $3.0 million , generating a net loss of $8,000 . For the three months ended March 31, 2018 , we had a maturity on one investment security of $2.0 million generating no gain or loss.

At March 31, 2019 , loans totaling $480.7 million were pledged to secure borrowings from the FHLB of Des Moines compared to $471.4 million at December 31, 2018 . Credit Quality Indicators . The Company assigns a risk rating to all credit exposures based on a risk rating system designed to define the basic characteristics and identified risk elements of each credit extension. The Company utilizes a nine‑point risk rating system. A description of the general characteristics of the risk grades is as follows: • Grades 1 through 5: These grades are considered to be “pass” credits. These include assets where there is virtually no credit risk, such as cash secured loans with funds on deposit with the Bank. Pass credits also include credits that are on the Company’s watch list, where the borrower exhibits potential weaknesses, which may, if not checked or corrected, negatively affect the borrower’s financial capacity and threaten their ability to fulfill debt obligations in the future. • Grade 6: These credits, classified as “special mention”, possess weaknesses that deserve management’s close attention. Special mention assets do not expose the Company to sufficient risk to warrant adverse classification in the substandard, doubtful or loss categories. If left uncorrected, these potential weaknesses may result in deterioration in the Company’s credit position at a future date. • Grade 7: These credits, classified as “substandard”, present a distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. These credits have well defined weaknesses which jeopardize the orderly liquidation of the debt and are inadequately protected by the current net worth and payment capacity of the borrower or of any collateral pledged. • Grade 8: These credits are classified as “doubtful” and possess well defined weaknesses which make the full collection or liquidation of the loan highly questionable and improbable. This classification is used where significant risk exposures are perceived but the exact amount of the loss cannot yet be determined due to pending events. • Grade 9: Assets classified as “loss” are considered uncollectible and cannot be justified as a viable asset for the Company. There is little or no prospect of near term recovery and no realistic strengthening action of significance is pending. As of March 31, 2019, and December 31, 2018, the Company had no loans rated as doubtful or loss. The following tables represent a summary of loans at March 31, 2019, and December 31, 2018 by type and risk category: March 31, 2019 One-to-Four Multifamily Commercial Construction/ Business Consumer Total (1) (In thousands) Risk Rating: Pass $ 349,894 $ 167,843 $ 384,149 $ 112,380 $ 33,513 $ 14,292 $ 1,062,071 Special mention 795 — 537 2,130 — — 3,462 Substandard 643 — — — — 44 687 Total loans $ 351,332 $ 167,843 $ 384,686 $ 114,510 $ 33,513 $ 14,336 $ 1,066,220 _______________ (1) Net of LIP.

ALLL . When the Company classifies problem assets as either substandard or doubtful, pursuant to Federal regulations, it may establish a specific reserve in an amount deemed prudent to address the risk specifically or may allow the loss to be addressed in the general allowance. General allowances represent loss allowances which have been established to recognize the inherent risk associated with lending activities, but which, unlike specific allowances, have not been specifically allocated to the particular problem assets. When an insured institution classifies problem assets as a loss, pursuant to Federal regulations, it is required to charge-off such assets in the period in which they are deemed uncollectible. The determination as to the classification of the Company’s assets and the amount of valuation allowances is subject to review by bank regulators, who can require the establishment of additional loss allowances. Loan grades are used by the Company to identify and track potential problem loans which do not rise to the levels described for substandard, doubtful, or loss. The grades for watch and special mention are assigned to loans which have been criticized based upon known characteristics such as periodic payment delinquency or stale financial information from the borrower and/or guarantors. Loans identified as criticized (watch and special mention) or classified (substandard, doubtful or loss) are subject to problem loan reporting every three months.

Fair Value Disclosures [Abstract]
Fair Value	Fair Value The Company determines the fair values of its financial instruments based on the fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair values. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect its estimate for market assumptions. Valuation inputs refer to the assumptions market participants would use in pricing a given asset or liability using one of the three valuation techniques. Inputs can be observable or unobservable. Observable inputs are those assumptions that market participants would use in pricing the particular asset or liability. These inputs are based on market data and are obtained from an independent source. Unobservable inputs are assumptions based on the Company’s own information or estimate of assumptions used by market participants in pricing the asset or liability. Unobservable inputs are based on the best and most current information available on the measurement date. All inputs, whether observable or unobservable, are ranked in accordance with a prescribed fair value hierarchy: • Level 1 - Quoted prices for identical instruments in active markets. • Level 2 - Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable. • Level 3 - Instruments whose significant value drivers are unobservable. The Company used the following methods to measure fair value on a recurring or nonrecurring basis: • Financial instruments with book value equal to fair value: The fair value of financial instruments that are short-term or reprice frequently and that have little or no risk are considered to have a fair value equal to book value. These instruments include cash on hand and in banks, interest-earning deposits with banks, FHLB stock, accrued interest receivable and accrued interest payable. FHLB stock is not publicly-traded, however it may be redeemed on a dollar-for-dollar basis, for any amount the Bank is not required to hold, subject to the FHLB’s discretion. The fair value is therefore equal to the book value. • Investments available-for-sale: The fair value of all investments, excluding FHLB stock, was based upon quoted market prices for similar investments in active markets, identical or similar investments in markets that are not active and model-derived valuations whose inputs are observable. • Loans receivable: The fair value of loans receivable are based on the exit price notion, and are calculated from inputs reflective of current market pricing for similar instruments, to include current origination spreads, liquidity premiums, and credit adjustments. The fair value of nonperforming loans is estimated using the fair value of the underlying collateral. • Derivatives: The fair value of derivatives is based on dealer quotes, pricing models, discounted cash flow methodologies or similar techniques for which the determination of fair value may require significant management judgment or estimation. • Liabilities: The fair value of deposits with no stated maturity, such as statement savings, interest-bearing checking and money market accounts, is equal to the amount payable on demand. The fair value of certificates of deposit is based on the discounted value of contractual cash flows using current interest rates for certificates of deposit with similar remaining maturities. The fair value of FHLB advances is estimated based on discounting the future cash flows using current interest rates for debt with similar remaining maturities. • Off balance sheet commitments: No fair value adjustment is necessary for commitments made to extend credit, which represents commitments for loan originations or for outstanding commitments to purchase loans. These commitments are at variable rates, are for loans with terms of less than one year and have interest rates which approximate prevailing market rates, or are set at the time of loan closing. Fair value estimates are based on existing balance sheet financial instruments without attempting to estimate the value of anticipated future business. The fair value has not been estimated for assets and liabilities that are not considered financial instruments. The tables below present the balances of assets measured at fair value on a recurring basis (there were no transfers between Level 1, Level 2 and Level 3 recurring measurements) at March 31, 2019 and December 31, 2018 : Fair Value Measurements at March 31, 2019 Fair Value Measurements Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) (In thousands) Investments available-for-sale: Mortgage-backed investments: Fannie Mae $ 23,686 $ — $ 23,686 $ — Freddie Mac 6,319 — 6,319 — Ginnie Mae 22,013 — 22,013 — Other 8,953 — 8,953 — Municipal bonds 7,767 — 7,767 — U.S. Government agencies 46,607 — 46,607 — Corporate bonds 23,313 — 23,313 — Total available-for-sale 138,658 — 138,658 — Derivative fair value asset 1,203 — 1,203 — Total $ 139,861 $ — $ 139,861 $ — Fair Value Measurements at December 31, 2018 Fair Value Measurements Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) (In thousands) Investments available-for-sale: Mortgage-backed investments: Fannie Mae $ 23,643 $ — $ 23,643 $ — Freddie Mac 6,287 — 6,287 — Ginnie Mae 22,061 — 22,061 — Other 8,979 — 8,979 — Municipal bonds 10,544 — 10,544 — U.S. Government agencies 47,438 — 47,438 — Corporate bonds 23,218 — 23,218 — Total available-for-sale 142,170 — 142,170 — Derivative fair value asset 1,662 — 1,662 — Total $ 143,832 $ — $ 143,832 $ — The estimated fair value of Level 2 investments is based on quoted prices for similar investments in active markets, identical or similar investments in markets that are not active and model-derived valuations whose inputs are observable.

The fair value of impaired loans reflects the exit price and is calculated using the collateral value method or on a discounted cash flow basis. Inputs used in the collateral value method include appraised values, less estimated costs to sell. Some of these inputs may not be observable in the marketplace. Appraised values may be discounted based on management’s knowledge of the marketplace, subsequent changes in market conditions, or management’s knowledge of the borrower. OREO properties are measured at the lower of their carrying amount or fair value, less estimated costs to sell. Fair values are generally based on third party appraisals of the property, resulting in a Level 3 classification. In cases where the carrying amount exceeds the fair value, less estimated costs to sell, an impairment loss is recognized.

Leases [Abstract]
Leases	Leases The Company adopted ASU 2016-02 and ASU 2018-11 using the modified retrospective approach with an effective date of January 1, 2019, and recognized on the consolidated balance sheets a right-of-use asset (“ROU”) included in prepaid expenses and other assets and lease liabilities included in other liabilities. As such, prior year financial statements were not restated under the new standard. At March 31, 2019, the Company had ten operating leases for retail branch locations. The remaining lease terms range from 1.4 to 6.3 years, with most leases carrying optional extensions of 3-5 years. The Company will include optional lease term extensions in the ROU assets and lease liabilities when management believes it is reasonably certain that the term extension will be exercised, and will be determined based on indicators that the Company would have an economic incentive to extend the lease. The Company has elected to not apply ASU 2016-02 to short term leases, which are those that have a term of one year or less. To calculate the present value of lease payments not yet paid, the Company uses the incremental borrowing rate, which is equal to the FHLB advance rate for the term of the lease that was in place at each lease inception. The minimum monthly lease payments are generally based on square footage of the leased premises, with escalating minimum rent over the lease term. At March 31, 2019, the Company was committed to paying $51,000 per month in minimum monthly lease payments. The minimum monthly lease payment over the initial lease term, including any free rent period, was used to calculate the ROU and lease liability. The Company’s current leases do not include any non-lease components. Total lease expense included in the Company’s Consolidated Income Statement for the three months ended March 31, 2019, was $175,000 . This included the amortized lease expense under ASU 2016-02 combined with variable lease expenses for maintenance or other expenses as defined in the individual lease agreements. The right-of-use asset and lease liability both had a balance of $1.7 million on the Company’s consolidated balance sheet at March 31, 2019, and are amortizing over a weighted-average remaining term of 4.2 years . The weighted-average discount rate used to calculate the present value of future minimum lease payments was 2.96% at March 31, 2019. The following table provides a reconciliation between the undiscounted minimum lease payments at March 31, 2019 and the discounted lease liability at that date: March 31, 2019 (in thousands) Due through one year $ 527 Due after one year through two years 471 Due after two years through three years 300 Due after three years through four years 277 Due after four years through five years 176 Due after five years 112 Total minimum lease payments 1,863 Less: present value discount (118 ) Lease liability $ 1,745 The Company has secured a lease for a new retail branch in Kirkland, Washington. The initial lease term is for 65 months and includes options to extend the lease. The minimum rent will be determined at commencement and will increase annually thereafter. This lease was not included in the calculation of discounted lease payments at March 31, 2019.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities Disclosure [Text Block]	Derivatives The Company uses a derivative financial instrument, which qualifies as a cash flow hedge, to manage the risk of changes in future cash flows due to interest rate fluctuations. The hedged instrument is a $50.0 million three-month FHLB advance that will be renewed every three months at the fixed interest rate at that time. The agreement has a five-year term and stipulates that the counterparty will pay the Company interest at three-month LIBOR and the Company will pay fixed interest of 1.34% on the $50.0 million notional amount. The Company pays or receives the net interest amount quarterly and includes this amount as part of interest expense on the Consolidated Income Statement. Quarterly, the effectiveness evaluation is based upon the fluctuation of the interest the Company pays to the FHLB for the hedge instrument as compared to the three-month LIBOR interest received from the counterparty. At March 31, 2019, the fair value of the cash flow hedge of $1.2 million was reported with other assets. The tax effected amount of $950,000 was included in Accumulated Other Comprehensive Income. There were no amounts recorded in the Consolidated Income Statements for the quarters ended March 31, 2019 or 2018 , related to ineffectiveness. Fair value for this derivative instrument, which generally changes as a result of changes in the level of market interest rates, is estimated based on dealer quotes and secondary market sources. The following table presents the fair value of this derivative instrument as of March 31, 2019 and December 31, 2018 : Balance Sheet Location Fair Value at March 31, 2019 Fair Value at December 31, 2018 (In thousands) Interest rate swap on FHLB debt designated as cash flow hedge Other Assets $ 1,203 $ 1,662 Total derivatives $ 1,203 $ 1,662 The following table presents the effect of this derivative instrument on the Consolidated Statements of Comprehensive Income for the quarters ended March 31, 2019 , and December 31, 2018 : Balance Sheet Location Amount Recognized in OCI at March 31, 2019 Amount Recognized in OCI at December 31, 2018 (In thousands) Interest rate swap on FHLB debt Other assets $ (363 ) $ 108

Stock-Based Compensation

Stock-Based Compensation	3 Months Ended

Share-based Compensation [Abstract]
Stock-Based Compensation	Stock-Based Compensation In June 2016, First Financial Northwest’s shareholders approved the First Financial Northwest, Inc. 2016 Equity Incentive Plan (“2016 Plan”). This plan provides for the granting of incentive stock options (“ISO”), non-qualified stock options (“NQSO”), restricted stock and restricted stock units until June 2026. The 2016 Plan established 1,400,000 shares available to grant with a maximum of 400,000 of these shares available to grant as restricted stock awards. Each share issued as a restricted stock award counts as two shares towards the total shares available to award. Under the 2016 Plan, the vesting date for each option award or restricted stock award is determined by an award committee and specified in the award agreement. In the case of restricted stock awards granted in lieu of cash payments of directors’ fees, the grant date is used as the vesting date unless the award agreement provides otherwise. As a result of the approval of the 2016 Plan, the First Financial Northwest, Inc. 2008 Equity Incentive Plan (“2008 Plan”) was frozen and no additional awards will be made. At March 31, 2019, there were no unvested shares of restricted stock awards under the 2008 Plan. At this date, there were 35,000 stock options granted under the 2008 Plan that are expected to vest and be available for exercise, and an additional 280,000 stock options from the 2008 Plan were available for exercise at March 31, 2019, subject to the 2008 Plan provisions. At March 31, 2019 , there were 1,207,274 total shares available for grant under the 2016 Plan, including 328,637 shares available to be granted as restricted stock. For the three months ended March 31, 2019 and 2018 , total compensation expense for both the 2008 and 2016 Plans was $124,000 and $84,000 , respectively, and the related income tax benefit was $26,000 and $18,000 , respectively. Stock Options Under the 2008 Plan, stock option awards were granted with an exercise price equal to the market price of First Financial Northwest’s common stock at the grant date. These option awards have a vesting period of 5 years, with 20% vesting on the anniversary date of each grant date, and a contractual life of 10 years. Any unexercised stock options expire ten years after the grant date, or sooner in the event of the award recipient’s death, disability or termination of service with the Company and the Bank. Under the 2016 Plan, the exercise price and vesting period for stock options are determined by the award committee and specified in the award agreement, however, the exercise price shall not be less than the fair market value of a share as of the grant date. Any unexercised stock option will expire 10 years after the award date or sooner in the event of the award recipient’s death, disability, retirement, or termination of service. The fair value of each option award is estimated on the grant date using a Black-Scholes model that uses the following assumptions. The dividend yield is based on the current quarterly dividend in effect at the time of the grant. Historical employment data is used to estimate the forfeiture rate. The historical volatility of the Company’s stock price over a specified period of time is used for the expected volatility assumption. First Financial Northwest bases the risk-free interest rate on the U.S. Treasury Constant Maturity Indices in effect on the date of the grant. First Financial Northwest elected to use the “Share-Based Payments” method permitted by the SEC to calculate the expected term. This method uses the vesting term of an option along with the contractual term, setting the expected life at the midpoint. Under certain conditions, a cashless exercise of vested stock options may occur by the option holder surrendering the number of options valued at the current stock price at the time of exercise to cover the total cost to exercise. The surrendered options are canceled and are unavailable for reissue. A summary of the Company’s stock option plan awards and activity for the three months ended March 31, 2019 , follows: For the Three Months Ended March 31, 2019 Shares Weighted-Average Exercise Price Weighted-Average Remaining Contractual Term in Years Aggregate Intrinsic Value Weighted-Average Grant Date Fair Value Outstanding at January 1, 2019 315,000 $ 10.34 $ 1,615,600 $ 3.69 Granted 50,000 15.80 5.03 Outstanding at March 31, 2019 365,000 11.09 5.43 1,703,800 3.88 Vested and expected to vest assuming a 3% forfeiture rate over the vesting term 362,450 11.07 5.41 1,699,668 3.87 Exercisable at March 31, 2019 280,000 10.16 4.59 1,566,070 3.61 As of March 31, 2019 , there was $323,000 of total unrecognized compensation cost related to nonvested stock options granted under the 2008 and 2016 Plans. The cost is expected to be recognized over the remaining weighted-average vesting period of 3.84 years. There were 50,000 stock options granted under the 2016 Plan during the three months ended March 31, 2019 . Restricted Stock Awards The 2016 Plan authorizes the grant of restricted stock awards subject to vesting periods or terms as defined by the award committee and specified in the award agreement. Restricted stock awards granted in lieu of cash payments for directors’ fees are subject to immediate vesting on the grant date unless the award agreement provides otherwise. A summary of changes in nonvested restricted stock awards for the three months ended March 31, 2019 , follows: For the Three Months Ended March 31, 2019 Shares Weighted-Average Nonvested at January 1, 2019 20,987 $ 15.90 Granted 16,698 16.53 Vested (20,987 ) 15.90 Nonvested at March 31, 2019 16,698 16.53 Expected to vest assuming a 3% forfeiture rate over the vesting term 16,197 16.53 As of March 31, 2019 , there was $247,000 of total unrecognized compensation costs related to nonvested shares granted as restricted stock awards. The cost is expected to be recognized over the remaining weighted-average vesting period of eleven months .

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share Per the provisions of FASB ASC 260, Earnings Per Share , nonvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents are participating securities and are included in the computation of EPS pursuant to the two-class method. The two-class method is an earnings allocation formula that determines earnings per share for each class of common stock and participating security according to dividends declared (or accumulated) and participation rights in undistributed earnings. ESOP shares are considered outstanding for basic and diluted earnings per share when the shares are committed to be released. Certain of the Company’s nonvested restricted stock awards qualify as participating securities. Net income is allocated between the common stock and participating securities pursuant to the two-class method, based on their rights to receive dividends, participate in earnings, or absorb losses. Basic earnings per common shares is computed by dividing net earnings available to common shareholders by the weighted-average number of common shares outstanding during the period, excluding participating nonvested restricted shares. The following table presents a reconciliation of the components used to compute basic and diluted earnings per share for the periods indicated: Three Months Ended March 31, 2019 2018 (Dollars in thousands, except share data) Net income $ 1,945 $ 6,842 Less: Earnings allocated to participating securities (3 ) (16 ) Earnings allocated to common shareholders $ 1,942 $ 6,826 Basic weighted average common shares outstanding 10,118,286 10,210,828 Dilutive stock options 89,718 122,465 Dilutive restricted stock grants 12,896 3,273 Diluted weighted average common shares outstanding 10,220,900 10,336,566 Basic earnings per share $ 0.19 $ 0.67 Diluted earnings per share $ 0.19 $ 0.66 Potential dilutive shares are excluded from the computation of earnings per share if their effect is anti-dilutive. For the three months ended March 31, 2019 , there were 50,000 options to purchase shares of common stock that were omitted from the computation of diluted earnings per share because their effect would be anti-dilutive. For the three months ended March 31, 2018, there no options to purchase shares of common stock that were omitted from the computation of diluted earnings per share because their effect would be anti-dilutive.

Business Combinations [Abstract]
Branch Acquisition	Branch Acquisition On August 25, 2017, First Financial Northwest Bank completed the acquisition of four branches from Opus Bank, a California state-chartered commercial bank. The Branch Acquisition included four retail branches located in Woodinville, Clearview, Lake Stevens, and Smokey Point, Washington. The Bank acquired $74.7 million of retail deposits, prior to the fair value adjustment, one owned bank branch, three leased branches, and certain fixed assets at these branches. The purchase price of the Branch Acquisition paid by the Bank included a deposit premium of 3.125% of the average daily balance of acquired deposits for 20 days prior to the closing date, or $2.5 million ; 80% of the fair market value of the owned branch, or $488,000 ; the net book value of fixed assets, or $56,000 ; and $14,000 for other pro rations and adjustments as of the closing date. Opus Bank paid the Bank $71.6 million in cash for the difference between these amounts and the total deposits assumed. The Branch Acquisition was accounted for under the acquisition method of accounting, and accordingly, the assets received and liabilities assumed were recorded at their fair market value as of August 25, 2017. The application of the acquisition method of accounting resulted in recognition of a core deposit intangible asset (“CDI”) of $1.3 million and goodwill of $889,000 . The acquired CDI has been determined to have a useful life of approximately ten years and is amortized on an accelerated basis. Goodwill is not amortized but will be evaluated for impairment on an annual basis, or more often if circumstances dictate, to determine if the carrying value remains appropriate. The balance of the CDI and goodwill at March 31, 2019 was $1.1 million and $889,000 , respectively.

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition In accordance with Topic 606, revenues are recognized when goods or services are transferred to the customer in exchange for the consideration the Company expects to be entitled to receive. To determine the appropriate recognition of revenue for transactions within the scope of Topic 606, the Company performs the following five steps: (i) identify the contract(s) with the customer; (ii) identify the separate performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the separate performance obligations in the contract; and (v) recognize revenue when the entity satisfies a performance obligation. A contract may not exist if there are doubts as to collectability of the amounts the Company is entitled to in exchange for the goods or services transferred. If a contract is determined to be within the scope of Topic 606, the Company recognizes revenue as it satisfies a performance obligation. The largest portion of the Company’s revenue is from net interest income which is not within the scope of Topic 606. Disaggregation of Revenue The following table includes the Company’s noninterest income disaggregated by type of service for the three months ended March 31, 2019 and 2018 : Three Months Ended March 31, 2019 March 31, 2018 (In thousands) Loss on sale of investments (1) $ (8 ) $ — BOLI change in cash surrender value (1) 269 249 Wealth management revenue 196 99 Deposit related fees 69 63 Debit card and ATM fees 102 98 Loan related fees 47 87 Loan interest swap fees 16 47 Other 9 3 Total noninterest income $ 700 $ 646 _______________ (1) Not within scope of Topic 606 For the three months ended March 31, 2019, substantially all of the Company’s revenues under the scope of Topic 606 are for performance obligations satisfied at a specified date. Revenues recognized within scope of Topic 606 Wealth management revenue: Our wealth management revenue consists of commissions received on the investment portfolio managed by Bank personnel but held by a third party. Commissions are earned on brokerage services and advisory services based on contract terms at the onset of a new customer’s investment agreement or quarterly for ongoing services. Commissions are paid by the third party to the Bank when the performance obligation has been completed by both entities. Deposit related fees: Fees are earned on our deposit accounts for various products or services performed for our customers. Fees include business account fees, non-sufficient fund fees, stop payment fees, wire services, safe deposit box, and others. These fees are recognized on a daily or monthly basis, depending on the type of service. Debit card and ATM fees: Fees are earned when a debit card issued by the Bank is used or when other bank’s customers use our ATM services. Revenue is recognized at the time the fees are collected from the customer’s account or remitted by the VISA interchange network. Loan related fees: Noninterest fee income is earned on our loans for servicing or annual fees on certain loan types. Loan interest swap fees: For loans participating in an interest rate swap agreement, fees are earned at the onset of the agreement and are not contingent on any future performance or term length of the loan itself. The performance obligation is satisfied by entering into the contract and receipt of the fees from the counterparty. Other: Fees earned on other services, such as merchant services or occasional non-recurring type services, are recognized at the time of the event or the applicable billing cycle. Contract Balances At March 31, 2019 , the Company had no contract liabilities where the Company had an obligation to transfer goods or services for which the Company had already received consideration. In addition, the Company had no material performance obligations as of this date.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recently Issued Accounting Pronouncements	Recent Accounting Pronouncements Adopted in 2019 In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842) . ASU No. 2016-02 requires lessees to recognize on the balance sheet the assets and liabilities arising from operating leases. In July 2018, FASB issued ASU No. 2018-11, Leases (Topic 842) to address the comparative reporting requirements when this ASU is adopted. In March 2019, FASB issued ASU 2019-01, Leases (Topic 842), Codification Improvements. Under these ASUs, a lessee should recognize a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term. A lessee should include payments to be made in an optional period only if the lessee is reasonably certain to exercise an option to extend the lease or not to exercise an option to terminate the lease. For a finance lease, interest payments should be recognized separately from amortization of the right-of-use asset in the statement of comprehensive income. For operating leases, the lease cost should be allocated over the lease term on a generally straight-line basis. The Company adopted this ASU on January 1, 2019 and according to ASU 2018-11, elected to recognize the related cumulative-effect adjustment as an adjustment to the opening balance of retained earnings. Adoption of ASU 2016-02 resulted in the addition of a right-of-use asset and lease related to certain banking offices under noncancelable operating lease agreements. The resulting increase did not to have a material impact on the Company’s consolidated financial statements or regulatory capital ratios. For more information see Note 8 ‑ Leases in this report. In March 2017, FASB issued ASU No. 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities . The ASU shortens the amortization period for certain callable debt securities held at a premium. The Company adopted this ASU during the quarter ended March 31, 2019 with no material impact on the Company's consolidated financial statements. Recent Accounting Pronouncements In June 2016, FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326). This ASU replaces the existing incurred loss impairment methodology that recognizes credit losses when a probable loss has been incurred with new methodology where loss estimates are based upon lifetime expected credit losses. The amendments in this ASU require a financial asset that is measured at amortized cost to be presented at the net amount expected to be collected. The income statement would then reflect the measurement of credit losses for newly recognized financial assets as well as changes to the expected credit losses that have taken place during the reporting period. The measurement of expected credit losses will be based on historical information, current conditions, and reasonable and supportable forecasts that impact the collectability of the reported amount. Available‑for‑sale securities will bifurcate the fair value mark and establish an allowance for credit losses through the income statement for the credit portion of that mark. The interest portion will continue to be recognized through accumulated other comprehensive income or loss. The change in allowance recognized as a result of adoption will occur through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the ASU is adopted. The amendments in this ASU are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, with early adoption permitted for fiscal years beginning after December 15, 2018. The Company is evaluating our current expected loss methodology of our loan and investment portfolios to identify the necessary modifications in accordance with this standard and expects a change in the processes and procedures to calculate the ALLL, 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. A valuation adjustment to our ALLL or investment portfolio that is identified in this process will be reflected as a one-time adjustment in equity rather than earnings. We are in the process of compiling historical and industry data that will be used to calculate expected credit losses on our loan portfolio to ensure we are fully compliant with the ASU at the adoption date and are evaluating the potential impact adoption of this ASU will have on our consolidated financial statements. The Company intends to adopt ASU 2016-13 in the first quarter of 2020, and as a result, we expect our allowance for loan losses to increase. Until our evaluation is complete, however, the magnitude of the increase will not be known.

At March 31, 2019 , loans totaling $480.7 million were pledged to secure borrowings from the FHLB of Des Moines compared to $471.4 million at December 31, 2018 . Credit Quality Indicators . The Company assigns a risk rating to all credit exposures based on a risk rating system designed to define the basic characteristics and identified risk elements of each credit extension. The Company utilizes a nine‑point risk rating system. A description of the general characteristics of the risk grades is as follows: • Grades 1 through 5: These grades are considered to be “pass” credits. These include assets where there is virtually no credit risk, such as cash secured loans with funds on deposit with the Bank. Pass credits also include credits that are on the Company’s watch list, where the borrower exhibits potential weaknesses, which may, if not checked or corrected, negatively affect the borrower’s financial capacity and threaten their ability to fulfill debt obligations in the future. • Grade 6: These credits, classified as “special mention”, possess weaknesses that deserve management’s close attention. Special mention assets do not expose the Company to sufficient risk to warrant adverse classification in the substandard, doubtful or loss categories. If left uncorrected, these potential weaknesses may result in deterioration in the Company’s credit position at a future date. • Grade 7: These credits, classified as “substandard”, present a distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. These credits have well defined weaknesses which jeopardize the orderly liquidation of the debt and are inadequately protected by the current net worth and payment capacity of the borrower or of any collateral pledged. • Grade 8: These credits are classified as “doubtful” and possess well defined weaknesses which make the full collection or liquidation of the loan highly questionable and improbable. This classification is used where significant risk exposures are perceived but the exact amount of the loss cannot yet be determined due to pending events. • Grade 9: Assets classified as “loss” are considered uncollectible and cannot be justified as a viable asset for the Company. There is little or no prospect of near term recovery and no realistic strengthening action of significance is pending. As of March 31, 2019, and December 31, 2018, the Company had no loans rated as doubtful or loss.
