Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying financial information is unaudited and has been prepared from the consolidated financial statements of Sound Financial Bancorp, Inc., and its wholly owned subsidiaries, Sound Community Bank and Sound Community Insurance Agency, Inc. References in this document to Sound Financial Bancorp refer to Sound Financial Bancorp, Inc. and references to the “Bank” refer to Sound Community Bank. References to “we,” “us,” and “our” or the “Company” refers to Sound Financial Bancorp and its wholly-owned subsidiaries, Sound Community Bank and Sound Community Insurance Agency, Inc., unless the context otherwise requires. These unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X as promulgated by the Securities and Exchange Commission (“SEC”). In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation of the financial position and results of operations for the periods presented have been included. Certain information and disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to the rules and regulations of the SEC. These unaudited financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2021, as filed with the SEC on March 15, 2022 (“2021 Form 10-K”). The results for the interim periods are not necessarily indicative of results for a full year or any other future period. Certain amounts in the prior period’s consolidated financial statements have been reclassified to conform to the current presentation. These classifications do not have an impact on previously reported consolidated net income, stockholders’ equity or earnings per share.

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 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. The change in allowance recognized as a result of adoption will occur through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the ASU is adopted. The new guidance may result in an increase in the allowance for loan losses; however, the Company is still in the process of determining the magnitude of the change and its impact on the Company's consolidated financial statements. 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 Bank meets the requirements of a smaller reporting company and will delay implementation of ASU No. 2016-13. In March 2022, the FASB issued ASU 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures . The ASU eliminates the accounting guidance for troubled debt restructured loans (“TDRs”) by creditors while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. Additionally, the ASU requires public business entities to disclose current-period gross write-offs by year of origination for financing receivables and net investments in leases. This ASU will be effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, upon the Company’s adoption of the amendments in ASU 2016-13, which is commonly referred to as the current expected credit loss methodology.

Investments [Abstract]
Investments	Investments The Company classifies its debt investment securities in two categories: held-to-maturity (“HTM”) or available-for-sale (“AFS”). Unrealized holding gains or losses, net of the related tax effect, on AFS securities are excluded from income and are reported as a separate component of stockholders’ equity as accumulated other comprehensive income (loss) net of applicable taxes until realized. Recognized gains and losses from the sale of AFS securities are determined on a specific-identification basis. These securities are adjusted for the amortization or accretion of premiums or discounts. 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. The Company does not own any debt securities classified as trading or equity securities. The amortized cost and fair value of our AFS securities and the corresponding amounts of gross unrealized gains and losses at the dates indicated were as follows (in thousands): Amortized Gross Gross Estimated September 30, 2022 Treasury bills $ 1,584 $ — $ (4) $ 1,580 Municipal bonds 6,705 25 (1,243) 5,487 Agency mortgage-backed securities 3,709 1 (381) 3,329 Total $ 11,998 $ 26 $ (1,628) $ 10,396 December 31, 2021 Municipal bonds $ 5,931 $ 148 $ (13) $ 6,066 Agency mortgage-backed securities 2,312 53 (12) 2,353 Total $ 8,243 $ 201 $ (25) $ 8,419 The amortized cost and fair value of our HTM securities and the corresponding amounts of gross unrealized gains and losses at the dates indicated were as follows (in thousands): Amortized Gross Gross Estimated September 30, 2022 Municipal bonds $ 705 $ — $ (202) $ 503 Agency mortgage-backed securities 1,502 — (251) 1,251 Total $ 2,207 $ — $ (453) $ 1,754 December 31, 2021 Municipal bonds $ — $ — $ — $ — Agency mortgage-backed securities — — — — Total $ — $ — $ — $ — The amortized cost and fair value of AFS and HTM securities at September 30, 2022, by contractual maturity, are shown below (in thousands).

The following table summarizes the aggregate fair value and gross unrealized loss by length of time of those investments that have been in a continuous unrealized loss position at the dates indicated (in thousands): September 30, 2022 Less Than 12 Months 12 Months or Longer Total Fair Unrealized Fair Unrealized Fair Unrealized Available-for-sale securities Treasury bills $ 1,580 $ (4) $ — $ — $ 1,580 $ (4) Municipal bonds 3,303 (1,094) 505 (149) 3,808 (1,243) Agency mortgage-backed securities 2,797 (288) 290 (93) 3,087 (381) Total available-for-sale securities $ 7,680 $ (1,386) $ 795 $ (242) $ 8,475 $ (1,628) Held-to-maturity securities Municipal bonds $ 503 $ (202) $ — $ — $ 503 $ (202) Agency mortgage-backed securities 1,251 (251) — — 1,251 (251) Total held-to-maturity securities $ 1,754 $ (453) $ — $ — $ 1,754 $ (453) December 31, 2021 Less Than 12 Months 12 Months or Longer Total Fair Unrealized Fair Unrealized Fair Unrealized Available-for-sale securities Municipal bonds $ 1,632 $ (13) $ — $ — $ 1,632 $ (13) Agency mortgage-backed securities — — 402 (12) 402 (12) Total $ 1,632 $ (13) $ 402 $ (12) $ 2,034 $ (25) There were no credit losses recognized in earnings related to other than temporary impairments during the three and nine months ended September 30, 2022 or 2021. At September 30, 2022, the total securities portfolio consisted of one treasury bill security, 12 agency mortgage-backed securities and 12 municipal bonds with a total portfolio fair value of $12.2 million. At December 31, 2021, the securities portfolio consisted of 10 agency mortgage-backed securities and 10 municipal bonds with a fair value of $8.4 million. At September 30, 2022, there were 18 securities in an unrealized loss position for less than 12 months, and two securities in an unrealized loss position for more than 12 months. Of the 18 securities in an unrealized loss position for less than 12 months, two securities were classified as HTM. At December 31, 2021, there were two securities in an unrealized loss position for less than 12 months, and one security in an unrealized loss position for more than 12 months. The unrealized losses were caused by changes in market interest rates or the widening of market spreads subsequent to the initial purchase of these securities, and not related to the underlying credit of the issuers or the underlying collateral. It is expected that these securities will not be settled at a price less than the amortized cost of each investment. The unrealized losses on these investments are not considered other-than-temporary impairment ("OTTI") as of September 30, 2022, because the decline in fair value is not attributable to credit quality and because we do not intend, and it is not likely that we will be required, to sell these securities before recovery of their amortized cost basis .

A loan is considered impaired when we determine that we may be unable to collect payments of principal or interest when due under the terms of the loan. In the process of identifying loans as impaired, we take 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. Impaired loans at the dates indicated, by type of loan were as follows (in thousands): September 30, 2022 Recorded Investment Unpaid Principal Without With Total Related One-to-four family $ 3,637 $ 2,713 $ 862 $ 3,575 $ 106 Home equity 203 133 70 203 5 Commercial and multifamily — — — — — Construction and land 63 29 34 63 3 Manufactured homes 193 68 125 193 101 Floating homes — — — — — Other consumer 364 265 100 365 24 Commercial business — — — — — Total $ 4,460 $ 3,208 $ 1,191 $ 4,399 $ 239 December 31, 2021 Recorded Investment Unpaid Principal Without With Total Related One-to-four family $ 4,177 $ 3,109 $ 957 $ 4,066 $ 112 Home equity 215 140 75 215 7 Commercial and multifamily 2,380 2,380 — 2,380 — Construction and land 68 33 35 68 4 Manufactured homes 221 44 177 221 144 Floating homes 493 493 — 493 — Other consumer 106 — 106 106 26 Commercial business 176 176 — 176 — Total $ 7,836 $ 6,375 $ 1,350 $ 7,725 $ 293 The following tables present the average recorded investment and interest income recognized on impaired loans for the periods indicated, by loan types (in thousands): Three Months Ended September 30, 2022 2021 Average Interest Income Average Interest Income One-to-four family $ 3,436 $ 32 $ 3,069 $ 60 Home equity 213 1 321 3 Commercial and multifamily 1,154 135 — — Construction and land 64 1 166 11 Manufactured homes 193 3 225 3 Floating homes — — 507 5 Other consumer 349 4 109 1 Commercial business — — 93 1 Total $ 5,409 $ 176 $ 4,490 $ 84 Nine Months Ended September 30, 2022 2021 Average Interest Income Average Interest Income One-to-four family $ 3,599 $ 76 $ 3,322 $ 118 Home equity 217 8 305 11 Commercial and multifamily 1,756 186 176 — Construction and land 66 3 121 12 Manufactured homes 206 12 244 12 Floating homes 123 — 511 12 Other consumer 288 13 111 4 Commercial business 86 — 353 1 Total $ 6,341 $ 298 $ 5,143 $ 170 Forgone interest on nonaccrual loans was $32 thousand and $89 thousand for the three months ended September 30, 2022 and 2021, respectively.

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 we classify problem assets as either substandard or doubtful, we may establish a specific allowance in an amount we deem prudent to address specific impairments. General allowances represent loss allowances which have been established to recognize the inherent risk associated with lending activities, but which, unlike specific allowances, have not been specifically allocated to particular problem assets. When an insured institution classifies problem assets as a loss, it is required to charge off those assets in the period in which they are deemed uncollectible. Our determination as to the classification of our assets and the amount of our valuation allowances is subject to review by the Federal Deposit Insurance Corporation (“FDIC”), the Bank's federal regulator, and, since our conversion to a Washington-chartered commercial bank, the Washington Department of Financial Institutions, the Bank's state banking regulator, which can order the establishment of additional loss allowances. Assets which do not currently expose us to sufficient risk to warrant classification in one of the aforementioned categories but possess weaknesses are required to be designated as special mention.

A loan is considered impaired when we determine that we may be unable to collect payments of principal or interest when due under the terms of the loan. In the process of identifying loans as impaired, we take 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. Impaired loans at the dates indicated, by type of loan were as follows (in thousands): September 30, 2022 Recorded Investment Unpaid Principal Without With Total Related One-to-four family $ 3,637 $ 2,713 $ 862 $ 3,575 $ 106 Home equity 203 133 70 203 5 Commercial and multifamily — — — — — Construction and land 63 29 34 63 3 Manufactured homes 193 68 125 193 101 Floating homes — — — — — Other consumer 364 265 100 365 24 Commercial business — — — — — Total $ 4,460 $ 3,208 $ 1,191 $ 4,399 $ 239 December 31, 2021 Recorded Investment Unpaid Principal Without With Total Related One-to-four family $ 4,177 $ 3,109 $ 957 $ 4,066 $ 112 Home equity 215 140 75 215 7 Commercial and multifamily 2,380 2,380 — 2,380 — Construction and land 68 33 35 68 4 Manufactured homes 221 44 177 221 144 Floating homes 493 493 — 493 — Other consumer 106 — 106 106 26 Commercial business 176 176 — 176 — Total $ 7,836 $ 6,375 $ 1,350 $ 7,725 $ 293 The following tables present the average recorded investment and interest income recognized on impaired loans for the periods indicated, by loan types (in thousands): Three Months Ended September 30, 2022 2021 Average Interest Income Average Interest Income One-to-four family $ 3,436 $ 32 $ 3,069 $ 60 Home equity 213 1 321 3 Commercial and multifamily 1,154 135 — — Construction and land 64 1 166 11 Manufactured homes 193 3 225 3 Floating homes — — 507 5 Other consumer 349 4 109 1 Commercial business — — 93 1 Total $ 5,409 $ 176 $ 4,490 $ 84 Nine Months Ended September 30, 2022 2021 Average Interest Income Average Interest Income One-to-four family $ 3,599 $ 76 $ 3,322 $ 118 Home equity 217 8 305 11 Commercial and multifamily 1,756 186 176 — Construction and land 66 3 121 12 Manufactured homes 206 12 244 12 Floating homes 123 — 511 12 Other consumer 288 13 111 4 Commercial business 86 — 353 1 Total $ 6,341 $ 298 $ 5,143 $ 170 Forgone interest on nonaccrual loans was $32 thousand and $89 thousand for the three months ended September 30, 2022 and 2021, respectively.

Fair Value Measurements

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 (“ASC 820”), 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 September 30, 2022 and December 31, 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 – HTM securities are recorded at amortized cost, adjusted for the amortization or accretion of premiums or discounts. 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 - One-to-four family mortgage loans held-for-sale are recorded at the lower of cost or fair value. The fair value of fixed-rate one-to-four family loans is based on whole loan forward prices obtained from government sponsored enterprises. At September 30, 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 mortgage servicing rights 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 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 three and nine months ended September 30, 2022 and 2021.

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 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. There were no assets or liabilities (excluding mortgage servicing rights) measured at fair value using significant unobservable inputs (Level 3) on a recurring basis during the three and nine months ended September 30, 2022 and 2021.

Earnings Per Share [Abstract]
Earnings Per Common Share	Earnings Per Common Share Basic earnings per common share is computed by dividing net income available to common shareholders by the weighted-average number of common shares outstanding for the period, reduced for average unallocated ESOP shares and average unvested restricted stock awards. Unvested share-based awards containing non-forfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and are included in the computation of earnings per share. Diluted earnings per common share reflect the potential dilution that could occur if securities or other contracts to issue common stock (such as stock awards and options) were exercised or converted to common stock or resulted in the issuance of common stock that then shared in the Company’s earnings. Diluted earnings per common share is computed by dividing net income by the weighted-average number of common shares outstanding for the period increased for the dilutive effect of unexercised stock options and unvested restricted stock awards. The dilutive effect of the unexercised stock options and unvested restricted stock awards is calculated under the treasury stock method utilizing the average market value of the Company's stock for the period. The following table summarizes the calculation of earnings per share for the periods indicated (in thousands, except per share data): Three Months Ended September 30, Nine Months Ended September 30, 2022 2021 2022 2021 Net income $ 2,546 $ 2,592 $ 5,881 $ 7,294 Weighted-average number of shares outstanding, basic 2,563 2,587 2,583 2,582 Effect of potentially dilutive common shares 35 46 35 43 Weighted-average number of shares outstanding, diluted 2,598 2,633 2,618 2,625 Earnings per share, basic (1)(2) $ 0.99 $ 1.00 $ 2.26 $ 2.81 Earnings per share, diluted (1)(2) $ 0.97 $ 0.98 $ 2.23 $ 2.76 (1) The basic and diluted earnings per share amounts include the impact of income allocated to participating securities of $17 thousand and $41 thousand for the three and nine months ended September 30, 2022, and $17 thousand and $50 thousand for the three and nine months ended September 30, 2021, respectively.

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. As of September 30, 2022, on an adjusted basis, awards for stock options totaling 283,484 shares and awards for restricted stock totaling 150,971 shares of Company common stock have been granted, net of any forfeitures, to participants in the 2013 Plan and the 2008 Plan. Share-based compensation expense was $90 thousand and $384 thousand for the three and nine months ended September 30, 2022, and $65 thousand and $295 thousand for the three and nine months ended September 30, 2021, respectively. Stock Option Awards All stock option awards granted under the 2008 Plan vest in 20% 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 award activity during the three months ended September 30, 2022 (dollars in thousands, except per share amounts): Shares Weighted- Weighted-Average Aggregate Outstanding at July 1, 2022 99,219 $ 26.94 5.21 $ 1,186 Granted — — Exercised (5,880) 18.72 Forfeited (20) 33.50 Expired (124) 36.82 Outstanding at September 30, 2022 93,195 27.45 4.84 1,248 Exercisable 71,749 24.32 3.77 1,169 Expected to vest, assuming a 0% forfeiture rate over the vesting term 93,195 $ 27.45 4.84 $ 1,248 The following is a summary of the Company’s stock option award activity during the nine months ended September 30, 2022 (dollars in thousands, except per share amounts): Shares Weighted- Weighted-Average Aggregate Outstanding at January 1, 2022 91,316 $ 24.59 4.77 $ 1,773 Granted 12,800 42.85 Exercised (9,751) 19.99 Forfeited (918) 34.92 Expired (252) 35.13 Outstanding at September 30, 2022 93,195 27.45 4.84 1,248 Exercisable 71,749 24.32 3.77 1,169 Expected to vest, assuming a 0% forfeiture rate over the vesting term 93,195 $ 27.45 4.84 $ 1,248 As of September 30, 2022, there was $128 thousand of total unrecognized compensation cost related to non-vested stock options granted under the Plans. The cost is expected to be recognized over the remaining weighted-average vesting period of approximately 2.7 years. 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 for the nine months ended September 30, 2022 and 2021 were determined using the following weighted-average assumptions as of the grant date. Nine Months Ended September 30, 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 There were zero and 12,800 options granted during the three and nine months ended September 30, 2022, and zero and 12,250 options granted during the three and nine months ended September 30, 2021, respectively. Restricted Stock Awards The fair value of the restricted stock awards is equal to the fair value of the Company's 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 award activity during the three months ended September 30, 2022: Shares Weighted-Average Aggregate Intrinsic Value Per Share Non-Vested at July 1, 2022 17,944 $ 37.62 Granted — — Vested — — Forfeited (20) 33.50 Non-Vested at September 30, 2022 17,924 37.62 40.52 Expected to vest assuming a 0% forfeiture rate over the vesting term 17,924 $ 37.62 $ 40.52 The following is a summary of the Company’s non-vested restricted stock award activity during the nine months ended September 30, 2022: Shares Weighted-Average Aggregate Intrinsic Value Per Share Non-Vested at January 1, 2022 17,586 $ 34.02 Granted 9,700 42.85 Vested (8,432) 36.34 Forfeited (930) 35.58 Non-Vested at September 30, 2022 17,924 37.62 40.52 Expected to vest assuming a 0% forfeiture rate over the vesting term 17,924 $ 37.62 $ 40.52 As of September 30, 2022, there was $477 thousand of unrecognized compensation cost related to non-vested restricted stock granted under the Plans. The cost is expected to be recognized over the weighted-average vesting period of 2.5 years. The total fair value of shares vested for the nine months ended September 30, 2022 and 2021 was $306 thousand and $264 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 was being repaid principally by the Bank through contributions to the ESOP over a period of ten years. The interest rate on the loan was fixed at 2.25% per annum. As of September 30, 2022, the ESOP loan was repaid in full. Neither the loan balance nor the related interest expense was reflected on the condensed consolidated financial statements. The fair value of the 158,001 shares held by the ESOP trust was $6.4 million at September 30, 2022. ESOP compensation expense included in salaries and benefits was $205 thousand and $580 thousand for the three and nine months ended September 30, 2022 and $180 thousand and $530 thousand for the three and nine months ended September 30, 2021, respectively.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying financial information is unaudited and has been prepared from the consolidated financial statements of Sound Financial Bancorp, Inc., and its wholly owned subsidiaries, Sound Community Bank and Sound Community Insurance Agency, Inc. References in this document to Sound Financial Bancorp refer to Sound Financial Bancorp, Inc. and references to the “Bank” refer to Sound Community Bank. References to “we,” “us,” and “our” or the “Company” refers to Sound Financial Bancorp and its wholly-owned subsidiaries, Sound Community Bank and Sound Community Insurance Agency, Inc., unless the context otherwise requires. These unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X as promulgated by the Securities and Exchange Commission (“SEC”). In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation of the financial position and results of operations for the periods presented have been included. Certain information and disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to the rules and regulations of the SEC. These unaudited financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2021, as filed with the SEC on March 15, 2022 (“2021 Form 10-K”). The results for the interim periods are not necessarily indicative of results for a full year or any other future period. Certain amounts in the prior period’s consolidated financial statements have been reclassified to conform to the current presentation. These classifications do not have an impact on previously reported consolidated net income, stockholders’ equity or earnings per share.
Accounting Pronouncements Recently Issued or Adopted	Accounting Pronouncements Recently Issued or Adopted On March 2020, the Financial Accounting Standards Board (“FASB”) issued 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. The change in allowance recognized as a result of adoption will occur through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the ASU is adopted. The new guidance may result in an increase in the allowance for loan losses; however, the Company is still in the process of determining the magnitude of the change and its impact on the Company's consolidated financial statements. 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 Bank meets the requirements of a smaller reporting company and will delay implementation of ASU No. 2016-13. In March 2022, the FASB issued ASU 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures . The ASU eliminates the accounting guidance for troubled debt restructured loans (“TDRs”) by creditors while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. Additionally, the ASU requires public business entities to disclose current-period gross write-offs by year of origination for financing receivables and net investments in leases. This ASU will be effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, upon the Company’s adoption of the amendments in ASU 2016-13, which is commonly referred to as the current expected credit loss methodology.
Fair Value Measurements	The Company determines the fair values of its financial instruments based on the requirements established in ASC 820 , Fair Value Measurements (“ASC 820”), 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 September 30, 2022 and December 31, 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 – HTM securities are recorded at amortized cost, adjusted for the amortization or accretion of premiums or discounts. 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 - One-to-four family mortgage loans held-for-sale are recorded at the lower of cost or fair value. The fair value of fixed-rate one-to-four family loans is based on whole loan forward prices obtained from government sponsored enterprises. At September 30, 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 mortgage servicing rights 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 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 three and nine months ended September 30, 2022 and 2021.
