Accounting Policies [Abstract]
Organization and Significant Accounting Policies	Organization and Significant Accounting Policies Sound Financial Bancorp, a Maryland corporation (“Sound Financial Bancorp”), is the parent holding company for its wholly owned subsidiary, Sound Community Bank (the “Bank”) and the Bank's wholly-owned subsidiary, Sound Community Insurance Agency, Inc. Substantially all of Sound Financial Bancorp's business is conducted through Sound Community Bank, a Washington state-chartered commercial bank. As a Washington commercial bank that is not a member of the Federal Reserve System, the Bank's regulators are the Washington State Department of Financial Institutions (“WDFI”) and the Federal Deposit Insurance Corporation (“FDIC”). As a bank holding company, Sound Financial Bancorp is regulated by the Board of Governors of the Federal Reserve System ("Federal Reserve"). Sound Financial Bancorp’s business activities generally are limited to passive investment activities and oversight of its investment in the Bank. Accordingly, the information set forth in this report relates primarily to the Bank. References to the “Company,” “we,” “us,” and “our” mean Sound Financial Bancorp and the Bank unless the context otherwise requires. Subsequent events – The Company has evaluated subsequent events for potential recognition and disclosure. See “Note 21—Subsequent Events” for further information. Basis of Presentation and Use of Estimates – The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, the fair value of MSRs, valuations of impaired loans and OREO, and the realization of deferred taxes. The accompanying consolidated financial statements include the accounts of Sound Financial Bancorp and its wholly-owned subsidiaries, Sound Community Bank and Sound Community Insurance Agency, Inc. All significant intercompany balances and transactions between Sound Financial Bancorp and its subsidiaries have been eliminated in consolidation. Cash and cash equivalents – For purposes of reporting cash flows, cash and cash equivalents include cash on hand and in banks and interest-bearing deposits. All have original maturities of three months or less and may exceed federally insured limits. Investment securities – Investment securities are classified as either held-to-maturity (“HTM”) or available-for-sale (“AFS”). Securities classified as HTM are those that the Company has the positive intent and ability to hold until maturity. These securities are carried at amortized cost, adjusted for the amortization or accretion of premiums or discounts. Securities not classified as HTM or trading are considered AFS securities. AFS securities may be sold to implement the Company's asset/liability management strategies and/or in response to changes in interest rates and similar factors. AFS securities are reported at fair value. Dividend and interest income on investment securities are recognized when earned. Unrealized gains and losses, net of the related deferred tax effect, are reported as a net amount in accumulated other comprehensive income (loss) on AFS securities in the consolidated balance sheets. Realized gains and losses on AFS securities, determined using the specific identification method, are included in earnings. Amortization of premiums and accretion of discounts are recognized as adjustments to interest income using the interest method over the period to the earlier of call date or maturity. The Company reviews investment securities on an ongoing basis for the presence of other-than-temporary impairment (“OTTI”) or permanent impairment, taking into consideration current market conditions, fair value in relation to cost, extent and nature of the change in fair value, issuer rating changes and trends, whether the Company intends to sell a security or if it is likely that the Company will be required to sell the security before recovery of its amortized cost basis of the investment, which may be maturity, and other factors. For debt securities, if the Company intends to sell the security or it is likely that it will be required to sell the 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 security and it is not likely that we will be required to sell the security but we do not expect to recover the entire amortized cost basis of the security, only the portion of the impairment loss representing credit losses would be recognized in earnings. The credit loss on a 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 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 the fair value, is recognized as a charge to other comprehensive income. The Company does not intend to sell these securities and it is more likely than not that it will not be required to sell the securities before anticipated recovery of the remaining amortized cost basis. The Company closely monitors its investment securities for changes in credit risk. Loans held-for-sale – To mitigate interest-rate sensitivity, from time to time, certain fixed-rate mortgage loans are identified as held-for-sale in the secondary market. Accordingly, such loans are classified as held-for-sale in the consolidated balance sheets and are carried at the lower of cost or estimated fair market value in the aggregate. Net unrealized losses, if any, are recognized through a valuation allowance by charges to income. Mortgage loans held-for-sale are generally sold with the mortgage servicing rights retained by the Company. Gains or losses on sales of loans are recognized based on the difference between the selling price and the carrying value of the related loans sold based on the specific identification method. Loans held-for-portfolio – The Company originates mortgage, commercial, and consumer loans to clients. A substantial portion of the loan portfolio is represented by loans secured by real estate located throughout the Puget Sound region, especially King, Snohomish and Pierce Counties, and in Clallam and Jefferson Counties of Washington State. The ability of the Company's debtors to honor their contracts is dependent upon employment, real estate and general economic conditions in these areas. Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off generally are reported at their outstanding unpaid principal balance adjusted for any charge-offs, allowance for loan losses, and any deferred fees or costs on origination of loans. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loan yield using the interest method over the contractual life of the loan for term loans or the straight-line method for open-ended loans. The accrual of interest is discontinued at the time the loan is 90 days past due or if, in management's opinion, the borrower may be unable to meet payment of obligations as they become due, as well as when required by regulatory provisions. Loans are typically charged off no later than 120 days past due, unless secured by collateral. Past due status is based on contractual terms of the loan. In all cases, loans are placed on nonaccrual or charged off at an earlier date if collection of principal or interest is considered doubtful. All interest accrued but not collected for loans that are placed on nonaccrual or charged-off is reversed against interest income. The interest on these loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all of the principal and interest amounts contractually due are brought current, future payments are reasonably assured and payments have been received for six A loan is considered impaired when it is probable that the Company will be unable to collect all amounts (principal and interest) due according to the contractual terms of the original loan agreement. When a loan has been identified as being impaired, the amount of the impairment is measured by using discounted cash flows, except when, as a practical expedient, the current fair value of the collateral, reduced by costs to sell, is used. When the measurement of the impaired loan is less than the recorded investment in the loan (including accrued interest), impairment is recognized by charging off the impaired portion or creating or adjusting a specific allocation of the allowance for loan losses. The Company recognizes interest income on impaired loans, including cash receipts, based on its existing methods of recognizing interest income on nonaccrual loans. A loan is classified as a troubled debt restructuring ("TDR") when certain concessions have been made to the contractual terms, such as reductions of interest rates or deferrals of interest or principal payments due to the borrower's deteriorated financial condition. All TDRs are reported and accounted for as impaired loans. Allowance for loan losses – The allowance for loan losses is a reserve established through a provision for loan losses charged to expense and represents management's best estimate of probable incurred losses within the existing loan portfolio as of the balance sheet date. The level of the allowance reflects management's view of trends in loan loss activity, current loan portfolio quality and present economic, political and regulatory conditions. Portions of the allowance may be allocated for specific loans; however, the allowance is available for any loan that is charged off. The allowance is increased by provisions charged to earnings and by recoveries of amounts previously charged off, and is reduced by charge-offs on loans (or portions thereof) deemed to be uncollectible. Loan charge-offs are recognized when management believes the collectability of the principal balance outstanding is unlikely. Full or partial charge-offs on collateral dependent impaired loans are generally recognized when the collateral is deemed to be insufficient to support the carrying value of the loan. The allowance for loan losses is maintained at a level sufficient to provide for probable credit losses based upon evaluating known and inherent risks in the loan portfolio. The allowance is provided based upon management's continuing analysis of the pertinent factors underlying the quality of the loan portfolio. These factors include changes in the size and composition of the loan portfolio, delinquency levels, actual loan loss experience, current economic conditions, and detailed analysis of individual loans for which full collectability may not be assured. The detailed analysis includes techniques to estimate the fair value of loan collateral and the existence of potential alternative sources of repayment. The allowance consists of specific, general and unallocated components. The general component of the allowance for loan losses covers non-impaired loans and is determined using a formula-based approach. The formula first incorporates either the historical loss rates of the Company or the historical loss rates of its peer group if minimal loss history exists. This historical loss rate factor is then adjusted for qualitative factors. Qualitative factors are used to estimate losses related to factors that are not captured in the historical loss rates and are based on management’s evaluation of available internal and external data and involve significant management judgement. Qualitative factors include changes in lending standards, changes in economic conditions, changes in the nature and volume of loans, changes in lending management, changes in delinquencies, changes in the loan review system, changes in the value of collateral, the existence of concentrations, and the impact of other external factors. Finally, the general component of the allowance for loan losses is adjusted for changes in the assigned grades of loans, which include the following: pass, watch, special mention, substandard, doubtful, and loss. As loans are downgraded from watch to the lower categories, they are assigned an additional factor to account for the increased credit risk. Loan grades involve significant management judgment. For such loans that are also classified as impaired, a specific component within the allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan are lower than the carrying value of that loan. An unallocated component is maintained to cover uncertainties that could affect management's estimate of probable losses. The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the portfolio. The Company considers installment loans to be pools of smaller balance, homogenous loans that are collectively evaluated for impairment, unless such loans are subject to a TDR agreement. The appropriateness of the allowance for loan losses is estimated based upon those factors and trends identified by management at the time consolidated financial statements are prepared. When available information confirms that specific loans or portions thereof are uncollectible, identified amounts are charged against the allowance for loan losses. The existence of some or all of the following criteria will generally confirm that a loss has been incurred: the loan is significantly delinquent and the borrower has not demonstrated the ability or intent to bring the loan current; the Company has no recourse to the borrower, or if it does, the borrower has insufficient assets to pay the debt; the estimated fair value of the loan collateral is significantly below the current loan balance, and there is little or no near-term prospect for improvement. The ultimate recovery of all loans is susceptible to future market factors beyond the Company's control. These factors may result in losses or recoveries differing significantly from those provided in the consolidated financial statements. Transfers of financial assets – Transfers of an entire financial asset, or a participating interest in an entire financial asset, are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when: (1) a group of financial assets or a participating interest in an entire financial asset has been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. Mortgage servicing rights – MSRs represent the value associated with servicing residential mortgage loans, when the mortgage loans have been sold into the secondary market and the related servicing has been retained by the Company. The Company may also purchase MSRs. The value is determined through a discounted cash flow analysis, which uses interest rates, prepayment speeds and delinquency rate assumptions as inputs. All of these assumptions require a significant degree of management judgment. The Company measures its mortgage servicing assets at fair value and reports changes in fair value through earnings under the caption fair value adjustment on MSRs in other income in the period in which the change occurs. The fair values of servicing rights are subject to significant fluctuations as a result of changes in estimates and actual prepayment speeds and default rates and losses. Currently, we do not hedge the effects of changes in fair value of our servicing assets. Premises and equipment – Premises, leasehold improvements and furniture and equipment are carried at cost, less accumulated depreciation and amortization. Furniture and equipment are depreciated using the straight-line method over the estimated useful lives of the assets, which range from 1 to 10 years. The cost of leasehold improvements is amortized using the straight-line method over the terms of the related leases. The cost of premises is amortized using the straight-line method over the estimated useful life of the building, up to 39 years. Management reviews premises, leasehold improvements and furniture and equipment for impairment when factors exist indicating potential impairment. Bank-owned life insurance, net – The carrying amount of BOLI approximates its fair value, and is estimated using the cash surrender value, net of any surrender charges. Federal Home Loan Bank stock – The Company is a member of the FHLB of Des Moines. FHLB stock represents the Company's investment in the FHLB and is carried at par value, which reasonably approximates its fair value. As a member of the FHLB, the Company is required to maintain a minimum level of investment in FHLB stock based on specific percentages of its outstanding mortgages, total assets, or FHLB advances. At December 31, 2022 and 2021, the Company's minimum required investment in FHLB stock was $2.8 million and $1.0 million, respectively. Typically, the Company may request redemption at par value of any stock in excess of the minimum required investment. Stock redemptions are at the discretion of the FHLB. Other real estate owned and repossessed assets – OREO and repossessed assets represent real estate and other assets which the Company has taken control of in partial or full satisfaction of loans. At the time of foreclosure, OREO and repossessed assets are recorded at fair value less estimated costs to sell, which becomes the new basis. Any write-downs based on the asset's fair value at the date of acquisition are charged to the allowance for loan and lease losses. After foreclosure, management periodically performs valuations such that the property is carried at the lower of its new cost basis or fair value, net of estimated costs to sell. Revenue and expenses from operations and subsequent adjustments to the carrying amount of the property are included in other noninterest expense in the consolidated statements of income. In some instances, the Company may make loans to facilitate the sales of OREO. Management reviews all sales for which it is the lending institution. Any gains related to sales of other real estate owned may be deferred until the buyer has a sufficient investment in the property. Leases – We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use assets and operating lease liabilities in our consolidated balance sheets. Right-of-use assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease right-of-use assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we generally use our incremental borrowing rate based on the estimated rate of interest for collateralized borrowing over a similar term of the lease payments at commencement date. The operating lease right-of-use asset also includes any lease payments made and excludes lease incentives. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Additionally, for equipment leases, we apply a portfolio approach to effectively account for the operating lease right-of-use assets and liabilities. The Company has not entered into leases that meet the definition of a financing lease. Income Taxes – Income taxes are accounted for using the asset and liability method. Under this method a deferred tax asset or liability is determined based on the enacted tax rates which will be in effect when the differences between the financial statement carrying amounts and tax basis of existing assets and liabilities are expected to be reported in the Company's income tax returns. The effect on deferred taxes of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation allowances are established to reduce the net carrying amount of deferred tax assets if it is determined to be more likely than not, that all or some portion of the potential deferred tax asset will not be realized. Segment reporting – The Company operates in one segment and makes management decisions based on consolidated results. The Company's operations are solely in the financial services industry and include providing to its clients traditional banking and other financial services. Off-balance-sheet credit-related financial instruments – In the normal course of operations, the Company engages in a variety of financial transactions that are not recorded in our financial statements. These transactions involve varying degrees of off-balance sheet credit, interest rate and liquidity risks. These transactions are used primarily to manage customers' requests for funding and take the form of loan commitments, letters of credit and lines of credit. Such financial instruments are recorded when they are funded. The Company also maintains a separate allowance for off-balance sheet credit commitments. Management estimates anticipated losses using historical data and utilization assumptions. The allowance for off-balance sheet credit commitments totaled $336 thousand and $405 thousand at December 31, 2022 and 2021, respectively, and is included in other liabilities on the consolidated balance sheets. Advertising costs – The Company expenses advertising costs as they are incurred. Advertising costs, including other marketing expenses were $390 thousand and $415 thousand for the years ended December 31, 2022 and 2021, respectively. Comprehensive income – Accounting principles generally require that recognized revenue, expenses, gains, and losses be included in net income. Certain changes in assets and liabilities, such as unrealized gains and losses on available-for-sale investments, are reported as a separate component of the equity section of the consolidated balance sheets, net of tax. Such items, along with net income, are components of comprehensive income. Intangible assets – At December 31, 2022 and 2021, the Company had $67 thousand and $97 thousand, respectively, of identifiable intangible assets included in other assets as a result of the acquisition of deposits from other institutions. These assets are amortized using the straight-line method over a period of eight Employee stock ownership plan – The Company sponsors an internally-leveraged ESOP. As shares are committed to be released, compensation expense is recorded equal to the market price of the shares, and the shares become outstanding for purposes of earnings per share calculations. Cash dividends on allocated shares (those credited to ESOP participants' accounts) are recorded as a reduction of stockholders' equity and distributed directly to participants' accounts. Cash dividends on unallocated shares (those held by the ESOP not yet credited to participants' accounts) are used to pay administrative expenses and debt service requirements of the ESOP. See "Note 14—Employee Benefits" for further information. Unearned ESOP shares are shown as a reduction of stockholders' equity. When the shares are released, unearned common shares held by the ESOP are reduced by the cost of the ESOP shares released and the differential between the fair value and the cost is charged to additional paid in capital. The loan receivable from the ESOP to the Company is not reported as an asset nor is the debt of the ESOP reported as a liability on the Company's consolidated statements of condition. Earnings Per Common Share – Earnings per share is computed using the two-class method. Basic earnings per share is computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the period, excluding any participating securities. Participating securities include unvested restricted shares. Unvested restricted shares are considered participating securities because holders of these securities receive non-forfeitable dividends at the same rate as the holders of the Company's common stock. Diluted earnings per share is computed by dividing net income available to common stockholders adjusted for reallocation of undistributed earnings of unvested restricted shares by the weighted average number of common shares determined for the basic earnings per share plus the dilutive effect of common stock equivalents using the treasury stock method based on the average market price for the period. Some stock options are anti-dilutive and therefore are not included in the calculation of diluted earnings per share. Fair value – Fair value is the price that would be received when an asset is sold or a liability is transferred in an orderly transaction between market participants at the measurement date. Fair values of the Company's financial instruments are based on the fair value hierarchy which requires an entity to maximize the use of observable inputs, typically market data obtained from third parties, and minimize the use of unobservable inputs, which reflects its estimates for market assumptions, when measuring fair value. Three levels of valuation inputs are ranked in accordance with the prescribed fair value hierarchy as follows: Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2: Quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active. Level 3: Assets or liabilities whose significant value drivers are unobservable. In determining the appropriate levels, the Company performs a detailed analysis of the assets and liabilities that are subject to fair value measurements. In certain cases, the inputs used to measure fair value of an asset or liability may fall into different levels of the fair value hierarchy. The level within which the fair value measurement is categorized is based on the lowest level unobservable input that is significant to the fair value measurement in its entirety. Therefore, an item may be classified in Level 3 even though there may be some significant inputs that are readily observable. Share-Based Compensation – The Company measures the cost of employee services received in exchange for an award of equity instruments based on the grant date fair value of the award. These costs are recognized on a straight-line basis over the vesting period during which an employee is required to provide services in exchange for the award, also known as the requisite service period. The Company uses the Black-Scholes option pricing model to estimate the fair value of stock options granted. When determining the estimated fair value of stock options granted, the Company utilizes various assumptions regarding the expected volatility of the stock price, the risk-free interest rate for periods within the contractual life of the stock option, and the expected dividend yield that the Company expects over the expected life of the options granted. Reductions in compensation expense associated with forfeited options are expensed based on actual forfeiture experience. The Company measures the fair value of the restricted stock using the closing market price of the Company's common stock on the date of grant. The Company expenses the grant date fair value of the Company's stock options and restricted stock with a corresponding increase in equity. When shares are required to be issued under share-based awards, it is typically the Company’s policy to issue new shares of stock.

Accounting Standards Update and Change in Accounting Principle [Abstract]
Accounting Pronouncements Recently Issued or Adopted	Accounting Pronouncements Recently Issued or Adopted On March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2020-04, " Reference Rate Reform" ("Topic 848"). This ASU provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The amendments in this update apply to modifications to eligible contracts (e.g., loans, debt securities, derivatives, borrowings) that replace a reference rate affected by reference rate reform (including rates referenced in fallback provisions) and contemporaneous modifications of other contract terms related to the replacement of the reference rate (including contract modifications to add or change fallback provisions). The following optional expedients for applying the requirements of certain Topics or Industry Subtopics in the Codification are permitted for contracts that are modified because of reference rate reform and that meet certain scope guidance: 1) Modifications of contracts within the scope of Topics 310, Receivables, and 470, Debt, should be accounted for by prospectively adjusting the effective interest rate; 2) Modifications of contracts within the scope of Topics 840, Leases, and 842, Leases, should be accounted for as a continuation of the existing contracts with no reassessments of the lease classification and the discount rate (for example, the incremental borrowing rate) or remeasurements of lease payments that otherwise would be required under those Topics for modifications not accounted for as separate contracts; and 3) Modifications of contracts do not require an entity to reassess its original conclusion about whether that contract contains an embedded derivative that is clearly and closely related to the economic characteristics and risks of the host contract under Subtopic 815-15, Derivatives and Hedging— Embedded Derivatives. In January 2021, ASU 2021-01 updated amendments in the new ASU to clarify that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. The ASU also amends the expedients and exceptions in Topic 848 to capture the incremental consequences of the scope clarification. The amendments in this ASU have differing effective dates, beginning with interim period including and subsequent to March 12, 2020 through December 31, 2022. The Company does not expect the adoption of ASU 2020-04 to have a material impact on its consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments and subsequent amendments to the initial guidance in November 2018, ASU No. 2018-19, April 2019, ASU 2019-04, May 2019, ASU 2019-05, November 2019, ASU 2019-11, February 2020, ASU 2020-02, and March 2020, ASU 2020-03, all of which clarifies codification and corrects unintended application of the guidance. 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. Financial assets that this guidance will apply to include loans receivable, held-to-maturity debt securities, unfunded loan commitments, and certain other financial assets measured at amortized cost. Under this ASU, available-for-sale debt securities are evaluated for impairment if fair value is less than amortized cost, with any estimated credit losses recorded through a credit loss expense and an allowance, rather than a write-down of the investment. Changes in fair value that are not credit-related will continue to be recorded in other comprehensive income. The change in allowance recognized as a result of adoption will occur using a modified retrospective approach through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the ASU is adopted. The FASB issued ASU No. 2019-10, Financial Instruments - Credit Losses (Topic 326) , delaying implementation of ASU No. 2016-13 for SEC smaller reporting company filers until fiscal years beginning after December 15, 2022. The Company meets the requirements of a smaller reporting company and delayed implementation of ASU No. 2016-13. This guidance became effective on January 1, 2023. The Company currently intends to phase the impact of Topic 326 into regulatory capital over three years in accordance with a final ruling effective April 2019 adopted by the Federal Reserve and other U.S. banking agencies. In March 2022, the FASB issued ASU 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures

Cash and Cash Equivalents [Abstract]
Restricted Cash	Restricted CashFederal Reserve System ("Federal Reserve") regulations previously required that the Company maintain certain minimum reserve balances either as cash on hand or on deposit with the Federal Reserve Bank, based on a percentage of deposits. In March 2020, the Federal Reserve announced that it would be reducing the reserve requirement for all depository institutions to zero percent effective March 26, 2020; therefore, there was no reserve requirement at December 31, 2022 and 2021.

Federal regulations provide for the classification of lower quality loans and other assets (such as OREO and repossessed assets), debt and equity securities considered as "substandard," "doubtful" or "loss." An asset is considered "substandard" if it is inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. "Substandard" assets include those characterized by the "distinct possibility" that the insured institution will sustain "some loss" if the deficiencies are not corrected. Assets classified as "doubtful" have all of the weaknesses in those classified "substandard," with the added characteristic that the weaknesses present make "collection or liquidation in full," on the basis of currently existing facts, conditions and values, "highly questionable and improbable." Assets classified as "loss" are those considered "uncollectible" and of such little value that their continuance as assets without the establishment of a specific loss reserve is not warranted. When the Company classifies problem loans as either substandard or doubtful, it may establish a specific allowance in an amount we deem prudent to address the risk specifically (if the loan is impaired) or it may allow the loss to be addressed in the general allowance (if the loan is not impaired). General allowances represent loss reserves which have been established to recognize the inherent risk associated with lending activities, but which, unlike specific allowances, have not been specifically allocated to particular problem assets. When the Company classifies problem loans as a loss, it charges-off such loans in the period in which they are deemed uncollectible. Assets that do not currently expose the Company to sufficient risk to warrant classification as substandard or doubtful, but possess identified weaknesses are classified as either watch or special mention loans. Determination as to the classification of our assets and the amount of our valuation allowances is subject to review by the FDIC, the Bank's federal regulator, and the WDFI, the Bank's state banking regulator, both of whom can order the establishment of additional loss allowances.

A loan is considered impaired when it is determined that the Company may not be able to collect payments of principal or interest when due under the terms of the loan. In the process of identifying loans as impaired, the Company takes into consideration factors which include payment history and status, collateral value, financial condition of the borrower, and the probability of collecting scheduled payments in the future. Minor payment delays and insignificant payment shortfalls typically do not result in a loan being classified as impaired. The significance of payment delays and shortfalls is considered on a case-by-case basis, after taking into consideration the totality of circumstances surrounding the loan and the borrower, including payment history. Impairment is measured on a loan-by-loan basis for all loans in the portfolio. All TDRs are also classified as impaired loans and are included in the loans individually evaluated for impairment in the calculation of the allowance for loan losses.

Troubled debt restructurings. TDRs, accounted for under ASC 310-40, are loans which have renegotiated loan terms to assist borrowers who are unable to meet the original terms of their loans. Such modifications to loan terms may include a lower interest rate, a reduction in principal, or a longer term to maturity. Once a TDR has performed according to its modified terms for six months and the collection of principal and interest under the revised terms is deemed probable, we remove the TDR from nonperforming status. Loans classified as TDRs totaled $2.0 million and $2.6 million at December 31, 2022 and 2021, respectively, and are included in impaired loans. The Company has granted, in its TDRs, a variety of concessions to borrowers in the form of loan modifications. The modifications granted can generally be described in the following categories: Rate Modification : A modification in which the interest rate is changed. Term Modification : A modification in which the maturity date, timing of payments or frequency of payments is changed. Payment Modifications: A modification in which the dollar amount of the payment is changed. Interest only modifications in which a loan is converted to interest only payments for a period of time are included in this category. Combination Modification : Any other type of modification, including the use of multiple categories above. There were two loans totaling $155 thousand that were modified as a TDR during the year ended December 31, 2022.

Fair Value Measurements

Fair Value Measurements	12 Months Ended
	Dec. 31, 2022
Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The Company determines the fair values of its financial instruments based on the requirements established in ASC 820 , Fair Value Measurements , which provides a framework for measuring fair value in accordance with U.S. GAAP and requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. ASC 820 defines fair values for financial instruments as the exit price, the price that would be received for an asset or paid to transfer a liability, in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date under current market conditions. The Company’s fair values for financial instruments at December 31, 2022 and 2021 were determined based on these requirements. The following methods and assumptions were used to estimate the fair value of other financial instruments: Cash and cash equivalents - The estimated fair value is equal to the carrying amount. Available-for-sale securities – AFS securities are recorded at fair value based on quoted market prices, if available. If quoted market prices are not available, management utilizes third-party pricing services or broker quotations from dealers in the specific instruments. Level 2 securities include those traded on an active exchange, as well as U.S. government securities. Held-to-maturity securities – The fair value is based on quoted market prices, if available. If quoted market prices are not available, management utilizes third-party pricing services or broker quotations from dealers in the specific instruments. Level 2 securities include those traded on an active exchange, as well as U.S. government securities. Loans held-for-sale - The fair value of fixed-rate one-to-four family loans is based on whole loan forward prices obtained from government sponsored enterprises. At December 31, 2022 and December 31, 2021, loans held-for-sale were carried at cost, as no impairment was required. Loans held-for-portfolio - The estimated fair value of loans-held-for portfolio consists of a credit adjustment to reflect the estimated adjustment to the carrying value of the loans due to credit-related factors and a yield adjustment, to reflect the estimated adjustment to the carrying value of the loans due to a differential in yield between the portfolio loan yields and estimated current market rate yields on loans with similar characteristics. The estimated fair values of loans held-for-portfolio reflect exit price assumptions. The liquidity premium/discounts are part of the valuation for exit pricing. Mortgage servicing rights –The fair value of MSRs is determined through a discounted cash flow analysis, which uses interest rates, prepayment speeds, discount rates, and delinquency rate assumptions as inputs. FHLB stock - The estimated fair value is equal to the par value of the stock. Non-maturity deposits - The estimated fair value is equal to the carrying amount. Time deposits - The estimated fair value of time deposits is based on the difference between interest costs paid on the Company’s time deposits and current market rates for time deposits with comparable characteristics. Borrowings - The fair value of borrowings are estimated using the contractual cash flows of each debt instrument discounted using the Company’s current incremental borrowing rates for similar types of borrowing arrangements. Subordinated notes - The fair value of subordinated notes is estimated using discounted cash flows based on current lending rates for similar long-term debt instruments with similar terms and remaining time to maturity. A description of the valuation methodologies used for impaired loans and OREO is as follows: Impaired loans - The fair value of collateral dependent loans is based on the current appraised value of the collateral less estimated costs to sell, or internally developed models utilizing a calculation of expected discounted cash flows which contain management’s assumptions. OREO and repossessed assets – The fair value of OREO and repossessed assets is based on the current appraised value of the collateral less estimated costs to sell. Off-balance sheet financial instruments - The fair value for the Company’s off-balance sheet loan commitments is estimated based on fees charged to others to enter into similar agreements taking into account the remaining terms of the agreements and credit standing of the Company’s clients. The estimated fair value of these commitments is not significant. In certain cases, the inputs used to measure fair value may fall into different levels of the hierarchy. In such cases, the lowest level of inputs that is significant to the measurement is used to determine the hierarchy for the entire asset or liability. Transfers between levels of the fair value hierarchy are recognized on the actual date of the event or circumstances that caused the transfer, which generally coincides with the Company’s quarterly valuation process. There were no transfers between levels during the years ended December 31, 2022 and 2021. The following tables present information about the level in the fair value hierarchy for the Company’s financial assets and liabilities, whether or not recognized or recorded at fair value, as of December 31, 2022 and 2021 (in thousands): December 31, 2022 Fair Value Measurements Using: Carrying Estimated Level 1 Level 2 Level 3 FINANCIAL ASSETS: Cash and cash equivalents $ 57,836 $ 57,836 $ 57,836 $ — $ — Available for sale securities 10,207 10,207 — 10,207 — Held-to-maturity securities 2,199 1,810 — 1,810 — Loans held-for-portfolio, net 858,382 801,153 — — 801,153 Mortgage servicing rights 4,687 4,687 — — 4,687 FHLB Stock 2,832 2,832 — 2,832 — FINANCIAL LIABILITIES: Non-maturity deposits 598,458 598,458 — 598,458 — Time deposits 210,305 209,965 — 209,965 — Borrowings 43,000 43,000 — 43,000 — Subordinated notes 11,676 10,420 — 10,420 — December 31, 2021 Fair Value Measurements Using: Carrying Estimated Level 1 Level 2 Level 3 FINANCIAL ASSETS: Cash and cash equivalents $ 183,590 $ 183,590 $ 183,590 $ — $ — Available for sale securities 8,419 8,419 — 8,419 — Loans held-for-sale 3,094 3,094 — 3,094 — Loans held-for-portfolio, net 680,092 675,154 — — 675,154 Mortgage servicing rights 4,273 4,273 — — 4,273 FHLB Stock 1,046 1,046 — 1,046 — FINANCIAL LIABILITIES: Non-maturity deposits 692,598 692,598 — 692,598 — Time deposits 105,722 106,834 — 106,834 — Subordinated notes 11,634 11,634 — 11,634 — The following tables present the balance of assets measured at fair value on a recurring basis at December 31, 2022 and 2021 (in thousands): Fair Value at December 31, 2022 Description Total Level 1 Level 2 Level 3 Treasury bills $ 1,594 $ — $ 1,594 $ — Municipal bonds 5,421 — 5,421 — Agency mortgage-backed securities 3,192 — 3,192 — MSRs 4,687 — — 4,687 Fair Value at December 31, 2021 Description Total Level 1 Level 2 Level 3 Municipal bonds $ 6,066 $ — $ 6,066 $ — Agency mortgage-backed securities 2,353 — 2,353 — MSRs 4,273 — — 4,273 The following table provides a description of the valuation technique, unobservable input, and qualitative information about the unobservable inputs for the Company's assets and liabilities classified as Level 3 and measured at fair value on a recurring basis at December 31, 2022: Financial Valuation Unobservable Input(s) Range MSRs Discounted cash flow Prepayment speed assumption 119%-461% (132%) Discount rate 10.5%-14.5% (12.5%) The following table provides a description of the valuation technique, unobservable input, and qualitative information about the unobservable inputs for the Company's assets and liabilities classified as Level 3 and measured at fair value on a recurring basis at December 31, 2021: Financial Valuation Unobservable Input(s) Range MSRs Discounted cash flow Prepayment speed assumption 204%-344% (205%) Discount rate 10.5%-14.5% (12.5%) Generally, any significant increases in the constant prepayment rate and discount rate utilized in the fair value measurement of the MSRs will result in a negative fair value adjustment (and decrease in the fair value measurement). Conversely, a decrease in the constant prepayment rate and discount rate will result in a positive fair value adjustment (and increase in the fair value measurement). An increase in the weighted average life assumptions will result in a decrease in the constant prepayment rate and conversely, a decrease in the weighted average life will result in an increase of the constant prepayment rate. As a result of the difficulty in observing certain significant valuation inputs affecting our “Level 3” fair value assets, we are required to make judgments regarding these items’ fair values. Different persons in possession of the same facts may reasonably arrive at different conclusions as to the inputs to be applied in valuing these assets and their fair values. Such differences may result in significantly different fair value measurements. There were no assets or liabilities (excluding MSRs) measured at fair value using significant unobservable inputs (Level 3) on a recurring basis during the years ended December 31, 2022 and 2021. MSRs are measured at fair value using significant unobservable input (Level 3) on a recurring basis and a reconciliation of this asset can be found in "Note 6—Mortgage Servicing Rights."

Employee Benefits

Employee Benefits	12 Months Ended

Share-Based Payment Arrangement [Abstract]
Employee Benefits	Employee Benefits The Company has a 401(k) retirement plan that allows employees to defer a portion of their salary into the 401(k) plan. The Company matches a portion of employees' salary deferrals. 401(k) plan costs are accrued and funded on a current basis. The Company contributed $259 thousand and $230 thousand to the plan for the years ended December 31, 2022 and 2021, respectively. The Bank maintains a deferred compensation account for the benefit of Ms. Stewart, established in 1994 in connection with an incentive plan which is no longer active. Ms. Stewart was fully vested in her benefits under this plan as of January 2005. Pursuant to the terms of the plan, payments in an amount equal to the fair market value of the assets in the deferred compensation account shall be made to Ms. Stewart (or to her designated beneficiary in the event of her death) in 120 equal monthly installments commencing on the last day of the month following the month in which her employment with the Bank is terminated. In the event of the death of Ms. Stewart and her designated beneficiary prior to the account being fully paid, the remaining value of the account shall be paid in a lump sum to the beneficiary’s estate. The assets in the deferred compensation account consist of cash, which is held in a certificate of deposit at the Bank and earns interest at market rates. At both December 31, 2022 and 2021, the amount held in the certificates of deposit at the Bank was $111 thousand. The Bank maintains a nonqualified deferred compensation plan (the “NQDC Plan”), which became effective on January 1, 2017. The purpose of the NQDC Plan is to provide a select group of management or highly-compensated employees of the Bank with an opportunity to defer the receipt of up to eighty percent (80%) of their annual base salary, bonus, performance-based compensation and any commission income and to assist the Company in attracting, retaining and motivating employees of high caliber and experience. In addition to elective deferrals, the Bank may make discretionary and other contributions to be credited to the account of any or all participants, subject to the vesting requirements set forth in the NQDC Plan. Discretionary contributions by the Bank become 100% vested upon the completion of three years of service from a participant’s effective date of participation in the NQDC Plan (with accelerated vesting upon death, disability or a change in control), while other Bank contributions (including matching contributions) vest at the rate of 20% per year, beginning with the participant’s two-year anniversary of his or her date of hire. During the years ended December 31, 2022, and 2021, the Bank made discretionary contributions to the NQDC Plan of $205 thousand and $93 thousand, respectively. Each participant’s deferred compensation account is credited with an investment return determined as if the account was invested in one or more investment funds. Each participant elects the investment funds in which his or her account shall be deemed to be invested. Distributions of vested account balances are made upon death, disability, separation from service, or a specified in-service date unforeseeable emergency. Distributions shall be made in a single cash payment or, at the election of the participant, in annual installments for a period of up to ten (10) years in the case of a separation from service and in annual installments for a period of up to five (5) years in the case of an in-service distribution. The obligations of the Bank under the NQDC Plan are general unsecured obligations of the Bank to pay deferred compensation in the future to eligible participants in accordance with the terms of the NQDC Plan from the general assets of the Bank, although the Bank may establish a trust to hold amounts which the Bank may use to satisfy NQDC Plan distributions from time to time. Distributions from the NQDC Plan are governed by the Internal Revenue Code and the NQDC Plan. The Company may, at any time, in its sole discretion, terminate the NQDC Plan or amend or modify the NQDC Plan, in whole or in part, except that no such termination, amendment or modification shall have any retroactive effect to reduce any amounts deemed to be accrued and vested prior to such amendment. Supplemental Executive Retirement Plans. The Company maintains two supplemental executive retirement plans for the benefit of Ms. Stewart, which are intended to be unfunded, non-contributory defined benefit plans maintained primarily to provide her with supplemental retirement income. The first supplemental executive retirement plan ("SERP 1") was effective as of August 14, 2007. The second supplemental executive retirement plan ("SERP 2") was effective as of December 30, 2011, at which time the benefits under SERP 1 were frozen. Under the terms of SERP 1, as amended, Ms. Stewart is entitled to receive $53,320 per year for life commencing on the first day of the month following her separation from service (as defined in SERP 1) for any reason from Sound Community Bank, subject to a six-month delay if required by Section 409A of the Internal Revenue Code. No payments will be made under SERP 1 in the event of Ms. Stewart's death and any payments that have commenced will cease upon death. In the event Ms. Stewart is involuntarily terminated in connection with a change in control (as defined in SERP 1), she will be entitled to receive the annual benefit described in the first sentence of this paragraph commencing upon such termination, subject to a six-month delay if required by Section 409A of the Internal Revenue Code. Under the terms of SERP 2, as amended, upon Ms. Stewart's termination of employment with Sound Community Bank for any reason other than death, she will be entitled to receive additional retirement benefits each month for life commencing on the first day of the month following her separation from service (as defined in SERP 2) from Sound Community Bank, subject to a six-month delay if required by Section 409A of the Internal Revenue Code. The additional retirement benefits will equal the amount payable from the annuity underlying SERP 2, which benefits would equal $99,450 per year as of December 31, 2022. In the event of Ms. Stewart's death prior to the commencement of the additional retirement benefits, her beneficiary will be entitled to a single lump sum payment within 90 days thereafter in an amount equal to the Bank's accrual for her retirement benefit under SERP 2 as of the date of death, or approximately $1.1 million at December 31, 2022. If a change in control occurs (as defined in SERP 2), Ms. Stewart will receive her full retirement benefit under SERP 2 commencing upon the first day of the month following her separation from service from Sound Community Bank, subject to a six-month delay if required by Section 409A of the Internal Revenue Code. Stock Options and Restricted Stock The Company currently has one active stockholder approved equity incentive plan, the Amended and Restated 2013 Equity Incentive Plan (the "2013 Plan"). The 2013 Plan permits the grant of restricted stock, restricted stock units, stock options, and stock appreciation rights. The equity incentive plan approved by stockholders in 2008 (the "2008 Plan") expired in November 2018 and no further awards may be made under the 2008 Plan; provided, however, all awards outstanding under the 2008 Plan remain outstanding in accordance with their terms. Under the 2013 Plan, 181,750 shares of common stock were approved for awards for stock options and stock appreciation rights and 116,700 shares of common stock were approved for awards for restricted stock and restricted stock units. At December 31, 2022, awards for stock options totaling 283,484 shares and awards for restricted stock totaling 150,971 shares of Company common stock have been granted in the aggregate, net of any forfeitures, under the 2008 Plan and 2013 Plan to participants. During the years ended December 31, 2022 and 2021, share-based compensation expense totaled $475 thousand and $360 thousand, respectively. Stock Option Awards All stock option awards granted under the 2008 Plan vest in 20 percent annual increments commencing one year from the grant date in accordance with the requirements of the 2008 Plan. The stock option awards granted to date under the 2013 Plan provide for immediate vesting of a portion of the award with the balance of the award vesting on the anniversary date of each grant date in equal annual installments over periods of one The following is a summary of the Company's stock option plan award activity during the period ended December 31, 2022: Shares Weighted-Average Weighted-Average Aggregate Outstanding at January 1, 2022 91,316 $ 24.59 4.77 $ 1,772,667 Granted 12,800 42.85 Exercised (11,421) 19.52 Forfeited (918) 34.92 Expired (252) 35.13 Outstanding at December 31, 2022 91,525 27.64 4.65 1,109,392 Exercisable 70,559 24.57 3.59 1,046,742 Expected to vest, assuming a 0% forfeiture rate over the vesting term 91,525 $ 27.64 4.65 $ 1,109,392 At December 31, 2022, there was $112 thousand of total unrecognized compensation cost related to non-vested stock options granted under the Plan. The cost is expected to be recognized over the remaining weighted-average vesting period of 2.5 years. The total intrinsic value of the shares exercised during the years ended December 31, 2022 and 2021 was $207 thousand and $447 thousand, respectively. The fair value of each option grant is estimated as of the grant date using the Black-Scholes option-pricing model. The fair value of options granted in 2022 and 2021 were determined using the following weighted-average assumptions as of the grant date. Year Ended December 31, 2022 2021 Annual dividend yield 1.59 % 1.60 % Expected volatility 26.48 % 21.67 % Risk-free interest rate 1.64 % 0.60 % Expected term 6.00 years 6.50 years Weighted-average grant date fair value per option granted $ 9.95 $ 5.64 Restricted Stock Awards The fair value of the restricted stock awards is equal to the fair value of the Company's common stock at the date of grant. Compensation expense is recognized over the vesting period that the awards are based. The restricted stock awards granted under the 2008 Plan vest in 20% annual increments commencing one year from the grant date. The restricted stock awards granted to date under the 2013 Plan provide for immediate vesting of a portion of the award with the balance of the award vesting on the anniversary date of each of the grant date in equal annual installments over periods of one The following is a summary of the Company's non-vested restricted stock awards for the year ended December 31, 2022: Non-vested Shares Shares Weighted-Average Aggregate Non-vested at January 1, 2022 17,586 $ 34.02 Granted 9,700 42.85 Vested (8,477) 36.34 Forfeited (930) 35.58 Expired — — Non-vested at December 31, 2022 17,879 37.63 $ 39.27 Expected to vest assuming a 0% forfeiture rate over the vesting term 17,879 $ 37.63 $ 39.27 At December 31, 2022, there was $403 thousand of unrecognized compensation cost related to non-vested restricted stock granted under the Plan. The cost is expected to be recognized over the weighted-average vesting period of 2.4 years. The total fair value of shares vested for the years ended December 31, 2022 and 2021 was $308 thousand and $265 thousand, respectively. Employee Stock Ownership Plan In January 2008, the ESOP borrowed $1.2 million from the Company to purchase common stock of the Company, which was paid in full in 2017. In August 2012, in conjunction with the Company's conversion to a full stock company from the mutual holding company structure, the ESOP borrowed an additional $1.1 million from the Company to purchase common stock of the Company. The loan for $1.1 million was being repaid principally by the Bank through contributions to the ESOP over a period of 10 years. The interest rate on the loan is fixed at 2.25%, per annum. At December 31, 2022, the remaining balance of the ESOP loan was zero. Neither the loan balance nor the related interest expense is reflected on the consolidated financial statements. For the year ended December 31, 2021, the ESOP was committed to release 11,340 shares of the Company's common stock to participants. There were no unallocated ESOP shares remaining to be released subsequent to December 31, 2021. The funds to purchase shares in the ESOP come from contributions the Bank makes up to twice a year to the Plan. For the years ended December 31, 2022 and 2021, the ESOP trustee purchased 19,438 shares and 7,343 shares of the Company's common stock for inclusion in the Plan. The number of allocated shares was 155,135 and 131,805 at December 31, 2022 and 2021, respectively. The fair value of the 155,135 restricted shares held by the ESOP trust was $6.4 million at December 31, 2022. ESOP compensation expense included in salaries and benefits was $820 thousand and $781 thousand for the years ended December 31, 2022 and 2021, respectively.

Capital

Broker-Dealer [Abstract]
Capital	Capital Sound Financial Bancorp is a bank holding company under the supervision of the Federal Reserve. Bank holding companies are subject to capital adequacy requirements of the Federal Reserve under the Bank Holding Company Act of 1956, as amended, and the regulations of the Federal Reserve, except that, pursuant to the Economic Growth, Regulatory Relief and Consumer Protection Act, effective August 30, 2018, a bank holding company with consolidated assets of less than $3.0 billion is generally not subject to the Federal Reserve’s capital regulations, which parallel the FDIC’s capital regulations.The Bank is a state-chartered, federally insured institution and thereby is subject to the capital requirements established by the FDIC. Failure to meet minimum capital requirements can initiate certain mandatory and, possibly, additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital regulations that involve quantitative measures of their assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. The capital amounts and classifications are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. Prompt corrective action provisions are not applicable to bank holding companies. At December 31, 2022, according to the most recent notification from the FDIC, the Bank was categorized as "well capitalized" under the regulatory framework for prompt corrective action. There are no conditions or events since the notification that management believes have changed the Bank’s category. As of January 1, 2020, the Bank elected to use the Community Bank Leverage Ratio (“CBLR”) framework as provided for in the Economic Growth, Regulatory Relief and Consumer Protection Act. To be eligible to utilize the CBLR, the Bank must have total consolidated assets of less than $10 billion, off-balance sheet exposures of 25% or less of its total consolidated assets, and trading assets and trading liabilities of 5.0% or less of its total consolidated assets, all as of the end of the most recent quarter. Under the CBLR framework, a bank will generally be considered well-capitalized and to have met the risk-based and leverage capital requirements of the capital regulations if it has a CBLR greater than 9.0%. A bank electing the framework that ceases to meet any qualifying criteria in a future period and that has a leverage ratio greater than 8% will be allowed a grace period of two reporting periods to satisfy the CBLR qualifying criteria or comply with the generally applicable capital requirements. A bank may opt out of the framework at any time, without restriction, by reverting to the generally applicable risk-based capital rule. At December 31, 2022, the Bank’s CBLR was 10.83%. For a bank holding company with less than $3.0 billion in assets, the capital guidelines apply on a bank-only basis and the Federal Reserve expects the holding company's subsidiary banks to be well-capitalized under the prompt corrective action regulations. If Sound Financial Bancorp was subject to regulatory guidelines for bank holding companies with $3.0 billion or more in assets, at December 31, 2022, Sound Financial Bancorp would have exceeded all regulatory capital requirements. The estimated CBLR calculated for Sound Financial Bancorp at December 31, 2022 was 9.86% During the years ended December 31, 2022 and 2021, the Company repurchased a total of 46,799 and 3,657 shares of Company common stock at an average price of $37.05 and $41.68 per share pursuant to the Company’s stock repurchase program, leaving $2.1 million available for future repurchase under the existing program.

These financial instruments generally represent a commitment to extend credit in the form of loans. The instruments involve, to varying degrees, elements of credit- and interest-rate risk in excess of the amount recognized in the consolidated balance sheets. The Company's exposure to credit loss, in the event of nonperformance by the other party to the financial instrument for commitments to extend credit, is represented by the contractual notional amount of those instruments. The Company uses the same credit policies in making commitments as it does for on-balance-sheet instruments. Commitments to extend credit are agreements to lend to a client as long as there is no violation of any condition established by the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Because many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. These commitments are not reflected in the consolidated financial statements. The Company evaluates each client's creditworthiness on a case-by-case basis. The amount of collateral obtained, if it is deemed necessary by the Company, is based on management's credit evaluation of the client. Financial instruments whose contract amount represents credit risk were as follow (in thousands): December 31, 2022 2021 Residential mortgage commitments $ 3,184 $ 6,663 Unfunded construction commitments 65,072 89,797 Unused lines of credit 32,793 35,036 Irrevocable letters of credit 275 151 Total loan commitments $ 101,323 $ 131,647 At December 31, 2022, fixed-rate loan commitments totaled $3.2 million and had a weighted-average interest rate of 7.60%. At December 31, 2021, fixed-rate loan commitments totaled $6.7 million and had a weighted-average interest rate of 4.27%. At December 31, 2022 and 2021, the Company had letters of credit issued by the FHLB with a notional amount of $8.0 million and $11.5 million, respectively, in order to secure Washington State Public Funds. In the ordinary course of business, the Company sells loans without recourse that may have to be subsequently repurchased due to defects that occurred during the origination of the loan. The defects are categorized as documentation errors, underwriting errors, early payment defaults, and fraud. When a loan sold to an investor without recourse fails to perform, the investor will typically review the loan file to determine whether defects in the origination process occurred. If a defect is identified, the Company may be required to either repurchase the loan or indemnify the investor for losses sustained. If there are no defects, the Company has no commitment to repurchase the loan. At December 31, 2022 and 2021, the maximum amount of these guarantees totaled $472.5 million and $508.1 million, respectively. These amounts represent the unpaid principal balances of the Company's loans serviced for others' portfolios. There were no loans repurchased during the year ended December 31, 2022 and $284 thousand of loans repurchased during the year ended 2021. The Company pays certain medical, dental, prescription, and vision claims for its employees, on a self-insured basis. The Company has purchased stop-loss insurance to cover claims that exceed stated limits and has recorded estimated reserves for the ultimate costs for both reported claims and claims incurred but not reported, which were not considered significant at December 31, 2022. At December 31, 2022, the Company recorded $227 thousand of stop loss medical insurance claims exceeding stated coverage limits which offset our medical expense during the year ended December 31, 2022. At various times, the Company may be the defendant in various legal proceedings arising in connection with its business. It is the opinion of management that the financial position and the results of operations of the Company will not be materially adversely affected by the outcome of any currently pending legal proceedings and that adequate provision has been made in the accompanying consolidated balance sheets.

Revenue from Contract with Customer [Abstract]
Revenue from Contracts with Customers	Revenue from Contracts with Customers All of the Company's revenue from contracts with customers in the scope of ASC 606— Revenue from Contracts with Customers ("ASC 606") is recognized in Noninterest Income with the exception of the net loss on OREO and repossessed assets, which is included in Noninterest Expense. The following table presents the Company's sources of Noninterest Income for the year ended December 31, 2022 and 2021 (in thousands). Items outside of the scope of ASC 606 are noted as such. Year Ended December 31, 2022 2021 Noninterest income: Service charges and fee income Account maintenance fees $ 324 $ 311 Transaction-based and overdraft service charges 446 356 Debit/ATM interchange fees 1,394 1,322 Credit card interchange fees 40 27 Loan fees (a) 119 178 Other fees (a) 45 53 Total service charges and fee income 2,368 2,247 Earnings on cash surrender value of bank-owned life insurance (a) 219 416 Mortgage servicing income (a) 1,242 1,284 Fair value adjustment on MSRs (a) 207 (808) Net gain on sale of loans (a) 546 4,190 Total noninterest income $ 4,582 $ 7,329 (a) Not within scope of ASC 606 Account maintenance fees and transaction-based and overdraft service charges The Company earns fees from its customers for account maintenance, transaction-based and overdraft services. Account maintenance fees consist primarily of account fees and analyzed account fees charged on deposit accounts on a monthly basis.The performance obligation is satisfied and fees are recognized on a monthly basis as the service period is completed. Transaction-based fees and overdraft service fees on deposit accounts are charged to deposit customers for specific services provided to the customer, such as non-sufficient funds, overdraft, and wire services. The performance obligation is completed as the transaction occurs and the fees are recognized at the time each specific service is provided to the customer. Debit/ATM and credit card interchange income Debit/ATM interchange income represent fees earned when a debit card issued by the Bank is used for a transaction. The Bank earns interchange fees from debit cardholder transactions through the MasterCard payment network. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value and are recognized daily, concurrently with the transaction processing services provided to the cardholder. The performance obligation is satisfied and the fees are earned when the cost of the transaction is charged to the cardholders' account. Certain expenses directly associated with the debit card are recorded on a net basis with the interchange income. The Company utilizes a third-party agency relationship to brand credit cards with fees for originating new accounts paid by the issuing bank. Credit card interchange income represents fees earned when a credit card is issued by the third-party agent. Similar to debit card interchange fees, the Bank earns an interchange fee for each transaction made with Sound Community Bank's branded credit cards. The performance obligation is satisfied and the fees are earned when the cost of the transaction is charged to the cardholders' credit card. Certain expenses and rebates directly related to the credit card interchange contract are recorded net of the interchange income. Net loss on OREO and repossessed assets We record a gain or loss from the sale of other real estate owned when control of the property transfers to the buyer, which generally occurs at the time of an executed deed of trust. When the Bank finances the sale of OREO to the buyer, the Company assesses whether the buyer is committed to perform their obligations under the contract and whether collectability of the transaction price is probable. Once these criteria are met, the OREO asset is derecognized and the gain or loss on sale is recorded upon the transfer of control of the property to the buyer. In determining the gain or loss on sale, we adjust the transaction price and related gain or loss on sale if a significant financing component is present. The Company generated income/incurred expenses, net of gain/losses on sale of OREO, on our OREO properties of $0 and $(16) thousand for the years ended December 31, 2022 and 2021, respectively, included under noninterest expense on the Consolidated Statements of Income.

Organization and Significant Accounting Policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
Subsequent events	Subsequent events – The Company has evaluated subsequent events for potential recognition and disclosure.
Basis of Presentation and Use of Estimates	Basis of Presentation and Use of Estimates – The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, the fair value of MSRs, valuations of impaired loans and OREO, and the realization of deferred taxes. The accompanying consolidated financial statements include the accounts of Sound Financial Bancorp and its wholly-owned subsidiaries, Sound Community Bank and Sound Community Insurance Agency, Inc. All significant intercompany balances and transactions between Sound Financial Bancorp and its subsidiaries have been eliminated in consolidation.
Cash and cash equivalents	Cash and cash equivalents – For purposes of reporting cash flows, cash and cash equivalents include cash on hand and in banks and interest-bearing deposits. All have original maturities of three months or less and may exceed federally insured limits.
Investment securities	Investment securities – Investment securities are classified as either held-to-maturity (“HTM”) or available-for-sale (“AFS”). Securities classified as HTM are those that the Company has the positive intent and ability to hold until maturity. These securities are carried at amortized cost, adjusted for the amortization or accretion of premiums or discounts. Securities not classified as HTM or trading are considered AFS securities. AFS securities may be sold to implement the Company's asset/liability management strategies and/or in response to changes in interest rates and similar factors. AFS securities are reported at fair value. Dividend and interest income on investment securities are recognized when earned. Unrealized gains and losses, net of the related deferred tax effect, are reported as a net amount in accumulated other comprehensive income (loss) on AFS securities in the consolidated balance sheets. Realized gains and losses on AFS securities, determined using the specific identification method, are included in earnings. Amortization of premiums and accretion of discounts are recognized as adjustments to interest income using the interest method over the period to the earlier of call date or maturity. The Company reviews investment securities on an ongoing basis for the presence of other-than-temporary impairment (“OTTI”) or permanent impairment, taking into consideration current market conditions, fair value in relation to cost, extent and nature of the change in fair value, issuer rating changes and trends, whether the Company intends to sell a security or if it is likely that the Company will be required to sell the security before recovery of its amortized cost basis of the investment, which may be maturity, and other factors. For debt securities, if the Company intends to sell the security or it is likely that it will be required to sell the 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 security and it is not likely that we will be required to sell the security but we do not expect to recover the entire amortized cost basis of the security, only the portion of the impairment loss representing credit losses would be recognized in earnings. The credit loss on a 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 security being measured for potential OTTI.
Loans held-for-sale	Loans held-for-sale – To mitigate interest-rate sensitivity, from time to time, certain fixed-rate mortgage loans are identified as held-for-sale in the secondary market. Accordingly, such loans are classified as held-for-sale in the consolidated balance sheets and are carried at the lower of cost or estimated fair market value in the aggregate. Net unrealized losses, if any, are recognized through a valuation allowance by charges to income. Mortgage loans held-for-sale are generally sold with the mortgage servicing rights retained by the Company. Gains or losses on sales of loans are recognized based on the difference between the selling price and the carrying value of the related loans sold based on the specific identification method.
Loans held-for-portfolio and Allowance for loan losses	Loans held-for-portfolio – The Company originates mortgage, commercial, and consumer loans to clients. A substantial portion of the loan portfolio is represented by loans secured by real estate located throughout the Puget Sound region, especially King, Snohomish and Pierce Counties, and in Clallam and Jefferson Counties of Washington State. The ability of the Company's debtors to honor their contracts is dependent upon employment, real estate and general economic conditions in these areas. Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off generally are reported at their outstanding unpaid principal balance adjusted for any charge-offs, allowance for loan losses, and any deferred fees or costs on origination of loans. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loan yield using the interest method over the contractual life of the loan for term loans or the straight-line method for open-ended loans. The accrual of interest is discontinued at the time the loan is 90 days past due or if, in management's opinion, the borrower may be unable to meet payment of obligations as they become due, as well as when required by regulatory provisions. Loans are typically charged off no later than 120 days past due, unless secured by collateral. Past due status is based on contractual terms of the loan. In all cases, loans are placed on nonaccrual or charged off at an earlier date if collection of principal or interest is considered doubtful. All interest accrued but not collected for loans that are placed on nonaccrual or charged-off is reversed against interest income. The interest on these loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all of the principal and interest amounts contractually due are brought current, future payments are reasonably assured and payments have been received for six A loan is considered impaired when it is probable that the Company will be unable to collect all amounts (principal and interest) due according to the contractual terms of the original loan agreement. When a loan has been identified as being impaired, the amount of the impairment is measured by using discounted cash flows, except when, as a practical expedient, the current fair value of the collateral, reduced by costs to sell, is used. When the measurement of the impaired loan is less than the recorded investment in the loan (including accrued interest), impairment is recognized by charging off the impaired portion or creating or adjusting a specific allocation of the allowance for loan losses. The Company recognizes interest income on impaired loans, including cash receipts, based on its existing methods of recognizing interest income on nonaccrual loans. A loan is classified as a troubled debt restructuring ("TDR") when certain concessions have been made to the contractual terms, such as reductions of interest rates or deferrals of interest or principal payments due to the borrower's deteriorated financial condition. All TDRs are reported and accounted for as impaired loans. Allowance for loan losses – The allowance for loan losses is a reserve established through a provision for loan losses charged to expense and represents management's best estimate of probable incurred losses within the existing loan portfolio as of the balance sheet date. The level of the allowance reflects management's view of trends in loan loss activity, current loan portfolio quality and present economic, political and regulatory conditions. Portions of the allowance may be allocated for specific loans; however, the allowance is available for any loan that is charged off. The allowance is increased by provisions charged to earnings and by recoveries of amounts previously charged off, and is reduced by charge-offs on loans (or portions thereof) deemed to be uncollectible. Loan charge-offs are recognized when management believes the collectability of the principal balance outstanding is unlikely. Full or partial charge-offs on collateral dependent impaired loans are generally recognized when the collateral is deemed to be insufficient to support the carrying value of the loan. The allowance for loan losses is maintained at a level sufficient to provide for probable credit losses based upon evaluating known and inherent risks in the loan portfolio. The allowance is provided based upon management's continuing analysis of the pertinent factors underlying the quality of the loan portfolio. These factors include changes in the size and composition of the loan portfolio, delinquency levels, actual loan loss experience, current economic conditions, and detailed analysis of individual loans for which full collectability may not be assured. The detailed analysis includes techniques to estimate the fair value of loan collateral and the existence of potential alternative sources of repayment. The allowance consists of specific, general and unallocated components. The general component of the allowance for loan losses covers non-impaired loans and is determined using a formula-based approach. The formula first incorporates either the historical loss rates of the Company or the historical loss rates of its peer group if minimal loss history exists. This historical loss rate factor is then adjusted for qualitative factors. Qualitative factors are used to estimate losses related to factors that are not captured in the historical loss rates and are based on management’s evaluation of available internal and external data and involve significant management judgement. Qualitative factors include changes in lending standards, changes in economic conditions, changes in the nature and volume of loans, changes in lending management, changes in delinquencies, changes in the loan review system, changes in the value of collateral, the existence of concentrations, and the impact of other external factors. Finally, the general component of the allowance for loan losses is adjusted for changes in the assigned grades of loans, which include the following: pass, watch, special mention, substandard, doubtful, and loss. As loans are downgraded from watch to the lower categories, they are assigned an additional factor to account for the increased credit risk. Loan grades involve significant management judgment. For such loans that are also classified as impaired, a specific component within the allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan are lower than the carrying value of that loan. An unallocated component is maintained to cover uncertainties that could affect management's estimate of probable losses. The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the portfolio. The Company considers installment loans to be pools of smaller balance, homogenous loans that are collectively evaluated for impairment, unless such loans are subject to a TDR agreement. The appropriateness of the allowance for loan losses is estimated based upon those factors and trends identified by management at the time consolidated financial statements are prepared. When available information confirms that specific loans or portions thereof are uncollectible, identified amounts are charged against the allowance for loan losses. The existence of some or all of the following criteria will generally confirm that a loss has been incurred: the loan is significantly delinquent and the borrower has not demonstrated the ability or intent to bring the loan current; the Company has no recourse to the borrower, or if it does, the borrower has insufficient assets to pay the debt; the estimated fair value of the loan collateral is significantly below the current loan balance, and there is little or no near-term prospect for improvement.
Transfers of financial assets	Transfers of financial assets – Transfers of an entire financial asset, or a participating interest in an entire financial asset, are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when: (1) a group of financial assets or a participating interest in an entire financial asset has been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
Mortgage servicing rights	Mortgage servicing rights – MSRs represent the value associated with servicing residential mortgage loans, when the mortgage loans have been sold into the secondary market and the related servicing has been retained by the Company. The Company may also purchase MSRs. The value is determined through a discounted cash flow analysis, which uses interest rates, prepayment speeds and delinquency rate assumptions as inputs. All of these assumptions require a significant degree of management judgment. The Company measures its mortgage servicing assets at fair value and reports changes in fair value through earnings under the caption fair value adjustment on MSRs in other income in the period in which the change occurs. The fair values of servicing rights are subject to significant fluctuations as a result of changes in estimates and actual prepayment speeds and default rates and losses. Currently, we do not hedge the effects of changes in fair value of our servicing assets.
Premises and equipment	Premises and equipment – Premises, leasehold improvements and furniture and equipment are carried at cost, less accumulated depreciation and amortization. Furniture and equipment are depreciated using the straight-line method over the estimated useful lives of the assets, which range from 1 to 10 years. The cost of leasehold improvements is amortized using the straight-line method over the terms of the related leases. The cost of premises is amortized using the straight-line method over the estimated useful life of the building, up to 39 years. Management reviews premises, leasehold improvements and furniture and equipment for impairment when factors exist indicating potential impairment.
Bank-owned life insurance, net	Bank-owned life insurance, net – The carrying amount of BOLI approximates its fair value, and is estimated using the cash surrender value, net of any surrender charges.
Federal Home Loan Bank stock	Federal Home Loan Bank stock – The Company is a member of the FHLB of Des Moines. FHLB stock represents the Company's investment in the FHLB and is carried at par value, which reasonably approximates its fair value. As a member of the FHLB, the Company is required to maintain a minimum level of investment in FHLB stock based on specific percentages of its outstanding mortgages, total assets, or FHLB advances. Typically, the Company may request redemption at par value of any stock in excess of the minimum required investment. Stock redemptions are at the discretion of the FHLB.
Other real estate owned and repossessed assets	Other real estate owned and repossessed assets – OREO and repossessed assets represent real estate and other assets which the Company has taken control of in partial or full satisfaction of loans. At the time of foreclosure, OREO and repossessed assets are recorded at fair value less estimated costs to sell, which becomes the new basis. Any write-downs based on the asset's fair value at the date of acquisition are charged to the allowance for loan and lease losses. After foreclosure, management periodically performs valuations such that the property is carried at the lower of its new cost basis or fair value, net of estimated costs to sell. Revenue and expenses from operations and subsequent adjustments to the carrying amount of the property are included in other noninterest expense in the consolidated statements of income. In some instances, the Company may make loans to facilitate the sales of OREO. Management reviews all sales for which it is the lending institution. Any gains related to sales of other real estate owned may be deferred until the buyer has a sufficient investment in the property.
Leases	Leases – We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use assets and operating lease liabilities in our consolidated balance sheets. Right-of-use assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease right-of-use assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we generally use our incremental borrowing rate based on the estimated rate of interest for collateralized borrowing over a similar term of the lease payments at commencement date. The operating lease right-of-use asset also includes any lease payments made and excludes lease incentives. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Additionally, for equipment leases, we apply a portfolio approach to effectively account for the operating lease right-of-use assets and liabilities. The Company has not entered into leases that meet the definition of a financing lease.
Income Taxes	Income Taxes – Income taxes are accounted for using the asset and liability method. Under this method a deferred tax asset or liability is determined based on the enacted tax rates which will be in effect when the differences between the financial statement carrying amounts and tax basis of existing assets and liabilities are expected to be reported in the Company's income tax returns. The effect on deferred taxes of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation allowances are established to reduce the net carrying amount of deferred tax assets if it is determined to be more likely than not, that all or some portion of the potential deferred tax asset will not be realized.
Segment reporting	Segment reporting – The Company operates in one segment and makes management decisions based on consolidated results. The Company's operations are solely in the financial services industry and include providing to its clients traditional banking and other financial services.
Off-balance-sheet credit-related financial instruments	Off-balance-sheet credit-related financial instruments – In the normal course of operations, the Company engages in a variety of financial transactions that are not recorded in our financial statements. These transactions involve varying degrees of off-balance sheet credit, interest rate and liquidity risks. These transactions are used primarily to manage customers' requests for funding and take the form of loan commitments, letters of credit and lines of credit. Such financial instruments are recorded when they are funded. The Company also maintains a separate allowance for off-balance sheet credit commitments. Management estimates anticipated losses using historical data and utilization assumptions. The allowance for off-balance sheet credit commitments totaled $336 thousand and $405 thousand at December 31, 2022 and 2021, respectively, and is included in other liabilities on the consolidated balance sheets.
Advertising costs	Advertising costs – The Company expenses advertising costs as they are incurred.
Comprehensive income	Comprehensive income – Accounting principles generally require that recognized revenue, expenses, gains, and losses be included in net income. Certain changes in assets and liabilities, such as unrealized gains and losses on available-for-sale investments, are reported as a separate component of the equity section of the consolidated balance sheets, net of tax. Such items, along with net income, are components of comprehensive income.
Intangible assets	Intangible assets – At December 31, 2022 and 2021, the Company had $67 thousand and $97 thousand, respectively, of identifiable intangible assets included in other assets as a result of the acquisition of deposits from other institutions. These assets are amortized using the straight-line method over a period of eight
Employee stock ownership plan	Employee stock ownership plan – The Company sponsors an internally-leveraged ESOP. As shares are committed to be released, compensation expense is recorded equal to the market price of the shares, and the shares become outstanding for purposes of earnings per share calculations. Cash dividends on allocated shares (those credited to ESOP participants' accounts) are recorded as a reduction of stockholders' equity and distributed directly to participants' accounts. Cash dividends on unallocated shares (those held by the ESOP not yet credited to participants' accounts) are used to pay administrative expenses and debt service requirements of the ESOP. See "Note 14—Employee Benefits" for further information. Unearned ESOP shares are shown as a reduction of stockholders' equity. When the shares are released, unearned common shares held by the ESOP are reduced by the cost of the ESOP shares released and the differential between the fair value and the cost is charged to additional paid in capital. The loan receivable from the ESOP to the Company is not reported as an asset nor is the debt of the ESOP reported as a liability on the Company's consolidated statements of condition.
Earnings Per Common Share	Earnings Per Common Share – Earnings per share is computed using the two-class method. Basic earnings per share is computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the period, excluding any participating securities. Participating securities include unvested restricted shares. Unvested restricted shares are considered participating securities because holders of these securities receive non-forfeitable dividends at the same rate as the holders of the Company's common stock. Diluted earnings per share is computed by dividing net income available to common stockholders adjusted for reallocation of undistributed earnings of unvested restricted shares by the weighted average number of common shares determined for the basic earnings per share plus the dilutive effect of common stock equivalents using the treasury stock method based on the average market price for the period. Some stock options are anti-dilutive and therefore are not included in the calculation of diluted earnings per share.
Fair value	Fair value – Fair value is the price that would be received when an asset is sold or a liability is transferred in an orderly transaction between market participants at the measurement date. Fair values of the Company's financial instruments are based on the fair value hierarchy which requires an entity to maximize the use of observable inputs, typically market data obtained from third parties, and minimize the use of unobservable inputs, which reflects its estimates for market assumptions, when measuring fair value. Three levels of valuation inputs are ranked in accordance with the prescribed fair value hierarchy as follows: Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2: Quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active. Level 3: Assets or liabilities whose significant value drivers are unobservable. In determining the appropriate levels, the Company performs a detailed analysis of the assets and liabilities that are subject to fair value measurements. In certain cases, the inputs used to measure fair value of an asset or liability may fall into different levels of the fair value hierarchy. The level within which the fair value measurement is categorized is based on the lowest level unobservable input that is significant to the fair value measurement in its entirety. Therefore, an item may be classified in Level 3 even though there may be some significant inputs that are readily observable.
Share-Based Compensation	Share-Based Compensation – The Company measures the cost of employee services received in exchange for an award of equity instruments based on the grant date fair value of the award. These costs are recognized on a straight-line basis over the vesting period during which an employee is required to provide services in exchange for the award, also known as the requisite service period. The Company uses the Black-Scholes option pricing model to estimate the fair value of stock options granted. When determining the estimated fair value of stock options granted, the Company utilizes various assumptions regarding the expected volatility of the stock price, the risk-free interest rate for periods within the contractual life of the stock option, and the expected dividend yield that the Company expects over the expected life of the options granted. Reductions in compensation expense associated with forfeited options are expensed based on actual forfeiture experience. The Company measures the fair value of the restricted stock using the closing market price of the Company's common stock on the date of grant. The Company expenses the grant date fair value of the Company's stock options and restricted stock with a corresponding increase in equity. When shares are required to be issued under share-based awards, it is typically the Company’s policy to issue new shares of stock.
Reclassifications	Reclassifications – Certain amounts reported in prior years consolidated financial statements may be reclassified to conform to the current presentation. The results of the reclassifications are typically not considered material and have no effect on previously reported net income, earnings per share or stockholders' equity. There were no reclassifications to prior year amounts in the current year.
Accounting pronouncements recently issued or adopted	Accounting Pronouncements Recently Issued or Adopted On March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2020-04, " Reference Rate Reform" ("Topic 848"). This ASU provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The amendments in this update apply to modifications to eligible contracts (e.g., loans, debt securities, derivatives, borrowings) that replace a reference rate affected by reference rate reform (including rates referenced in fallback provisions) and contemporaneous modifications of other contract terms related to the replacement of the reference rate (including contract modifications to add or change fallback provisions). The following optional expedients for applying the requirements of certain Topics or Industry Subtopics in the Codification are permitted for contracts that are modified because of reference rate reform and that meet certain scope guidance: 1) Modifications of contracts within the scope of Topics 310, Receivables, and 470, Debt, should be accounted for by prospectively adjusting the effective interest rate; 2) Modifications of contracts within the scope of Topics 840, Leases, and 842, Leases, should be accounted for as a continuation of the existing contracts with no reassessments of the lease classification and the discount rate (for example, the incremental borrowing rate) or remeasurements of lease payments that otherwise would be required under those Topics for modifications not accounted for as separate contracts; and 3) Modifications of contracts do not require an entity to reassess its original conclusion about whether that contract contains an embedded derivative that is clearly and closely related to the economic characteristics and risks of the host contract under Subtopic 815-15, Derivatives and Hedging— Embedded Derivatives. In January 2021, ASU 2021-01 updated amendments in the new ASU to clarify that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. The ASU also amends the expedients and exceptions in Topic 848 to capture the incremental consequences of the scope clarification. The amendments in this ASU have differing effective dates, beginning with interim period including and subsequent to March 12, 2020 through December 31, 2022. The Company does not expect the adoption of ASU 2020-04 to have a material impact on its consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments and subsequent amendments to the initial guidance in November 2018, ASU No. 2018-19, April 2019, ASU 2019-04, May 2019, ASU 2019-05, November 2019, ASU 2019-11, February 2020, ASU 2020-02, and March 2020, ASU 2020-03, all of which clarifies codification and corrects unintended application of the guidance. 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. Financial assets that this guidance will apply to include loans receivable, held-to-maturity debt securities, unfunded loan commitments, and certain other financial assets measured at amortized cost. Under this ASU, available-for-sale debt securities are evaluated for impairment if fair value is less than amortized cost, with any estimated credit losses recorded through a credit loss expense and an allowance, rather than a write-down of the investment. Changes in fair value that are not credit-related will continue to be recorded in other comprehensive income. The change in allowance recognized as a result of adoption will occur using a modified retrospective approach through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the ASU is adopted. The FASB issued ASU No. 2019-10, Financial Instruments - Credit Losses (Topic 326) , delaying implementation of ASU No. 2016-13 for SEC smaller reporting company filers until fiscal years beginning after December 15, 2022. The Company meets the requirements of a smaller reporting company and delayed implementation of ASU No. 2016-13. This guidance became effective on January 1, 2023. The Company currently intends to phase the impact of Topic 326 into regulatory capital over three years in accordance with a final ruling effective April 2019 adopted by the Federal Reserve and other U.S. banking agencies. In March 2022, the FASB issued ASU 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures
Fair value of financial instruments	The Company determines the fair values of its financial instruments based on the requirements established in ASC 820 , Fair Value Measurements , which provides a framework for measuring fair value in accordance with U.S. GAAP and requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. ASC 820 defines fair values for financial instruments as the exit price, the price that would be received for an asset or paid to transfer a liability, in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date under current market conditions. The Company’s fair values for financial instruments at December 31, 2022 and 2021 were determined based on these requirements. The following methods and assumptions were used to estimate the fair value of other financial instruments: Cash and cash equivalents - The estimated fair value is equal to the carrying amount. Available-for-sale securities – AFS securities are recorded at fair value based on quoted market prices, if available. If quoted market prices are not available, management utilizes third-party pricing services or broker quotations from dealers in the specific instruments. Level 2 securities include those traded on an active exchange, as well as U.S. government securities. Held-to-maturity securities – The fair value is based on quoted market prices, if available. If quoted market prices are not available, management utilizes third-party pricing services or broker quotations from dealers in the specific instruments. Level 2 securities include those traded on an active exchange, as well as U.S. government securities. Loans held-for-sale - The fair value of fixed-rate one-to-four family loans is based on whole loan forward prices obtained from government sponsored enterprises. At December 31, 2022 and December 31, 2021, loans held-for-sale were carried at cost, as no impairment was required. Loans held-for-portfolio - The estimated fair value of loans-held-for portfolio consists of a credit adjustment to reflect the estimated adjustment to the carrying value of the loans due to credit-related factors and a yield adjustment, to reflect the estimated adjustment to the carrying value of the loans due to a differential in yield between the portfolio loan yields and estimated current market rate yields on loans with similar characteristics. The estimated fair values of loans held-for-portfolio reflect exit price assumptions. The liquidity premium/discounts are part of the valuation for exit pricing. Mortgage servicing rights –The fair value of MSRs is determined through a discounted cash flow analysis, which uses interest rates, prepayment speeds, discount rates, and delinquency rate assumptions as inputs. FHLB stock - The estimated fair value is equal to the par value of the stock. Non-maturity deposits - The estimated fair value is equal to the carrying amount. Time deposits - The estimated fair value of time deposits is based on the difference between interest costs paid on the Company’s time deposits and current market rates for time deposits with comparable characteristics. Borrowings - The fair value of borrowings are estimated using the contractual cash flows of each debt instrument discounted using the Company’s current incremental borrowing rates for similar types of borrowing arrangements. Subordinated notes - The fair value of subordinated notes is estimated using discounted cash flows based on current lending rates for similar long-term debt instruments with similar terms and remaining time to maturity. A description of the valuation methodologies used for impaired loans and OREO is as follows: Impaired loans - The fair value of collateral dependent loans is based on the current appraised value of the collateral less estimated costs to sell, or internally developed models utilizing a calculation of expected discounted cash flows which contain management’s assumptions. OREO and repossessed assets – The fair value of OREO and repossessed assets is based on the current appraised value of the collateral less estimated costs to sell. Off-balance sheet financial instruments - The fair value for the Company’s off-balance sheet loan commitments is estimated based on fees charged to others to enter into similar agreements taking into account the remaining terms of the agreements and credit standing of the Company’s clients. The estimated fair value of these commitments is not significant. In certain cases, the inputs used to measure fair value may fall into different levels of the hierarchy. In such cases, the lowest level of inputs that is significant to the measurement is used to determine the hierarchy for the entire asset or liability. Transfers between levels of the fair value hierarchy are recognized on the actual date of the event or circumstances that caused the transfer, which generally coincides with the Company’s quarterly valuation process. There were no transfers between levels during the years ended December 31, 2022 and 2021.
