Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Significant Accounting Policies	Basis of Presentation and Significant Accounting Policies Nature of Operations PCB Bancorp is a bank holding company whose subsidiary is Pacific City Bank (the “Bank”). The Bank is a single operating segment that operates 11 full-service branches in Los Angeles and Orange counties, California, one full-service branch in each of Englewood Cliffs, New Jersey and Bayside, New York, and 10 loan production offices (“LPOs”) in Irvine, Artesia and Los Angeles, California; Annandale, Virginia; Atlanta, Georgia; Chicago, Illinois; Bellevue, Washington; Aurora, Colorado; Carrollton, Texas; and New York, New York. The Bank offers a broad range of loans, deposits, and other products and services predominantly to small and middle market businesses and individuals. Basis of Presentation The accompanying unaudited interim consolidated financial statements have been prepared pursuant to Article 10 of SEC Regulation S-X and other SEC rules and regulations for reporting on the Quarterly Report on Form 10-Q. Accordingly, certain disclosures required by U.S. generally accepted accounting principles (“GAAP”) are not included herein. These interim statements should be read in conjunction with the audited consolidated financial statements and notes included in the Annual Report on Form 10-K for the year ended December 31, 2020 filed by the Company with the SEC. The December 31, 2020 balance sheet presented herein has been derived from the audited financial statements included in the Annual Report on Form 10-K for the year ended December 31, 2020 filed with the SEC, but does not include all of the disclosures required by GAAP for complete financial statements. In the opinion of management of the Company, the accompanying unaudited interim consolidated financial statements reflect all of the adjustments (consisting of normal recurring adjustments) necessary for a fair presentation of the consolidated financial condition and consolidated results of operations as of the dates and for the periods presented. Certain reclassifications have been made in the prior period financial statements to conform to the current period presentation. The results of operations for the three and nine months ended September 30, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021. Principles of Consolidation The consolidated financial statements include the accounts of PCB Bancorp and its wholly owned subsidiary as of September 30, 2021 and December 31, 2020, and for the three and nine months ended September 30, 2021 and 2020. Significant inter-company accounts and transactions have been eliminated in consolidation. Unless the context requires otherwise, all references to the Company include its wholly owned subsidiary. Significant Accounting Policies The accounting and reporting policies of the Company are based upon GAAP and conform to predominant practices within the banking industry. The Company has not made any significant changes in its critical accounting policies from those disclosed in its Annual Report on Form 10-K for the year ended December 31, 2020 filed with the SEC. Use of Estimates in the Preparation of Financial Statements The preparation of the consolidated financial statements in conformity with 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 revenues and expenses during the reporting period. These estimates are subject to change and such change could have a material effect on the consolidated financial statements. Actual results may differ from those estimates. Reclassification of Securities Held-To-Maturity to Securities Available-For-Sale On June 30, 2020, the Company transferred securities held-to-maturity to securities available-for-sale as a part of the Company’s liquidity management plan in response to the COVID-19 pandemic. Management determined that its securities held-to-maturity no longer adhere to the Company’s current liquidity management plan and could be sold to potentially improve the Company’s liquidity position. Accordingly, the Company was no longer able to assert that it had the intent to hold these securities until maturity and the Company’s ability to assert that it has the intent and ability to hold to maturity debt securities will be limited for up to two years from the date of transfer. The Company transferred all securities held-to-maturity of $18.8 million to securities available-for-sale, which resulted in a pre-tax increase to accumulated other comprehensive income of $787 thousand. Loan Modifications Related to the COVID-19 Pandemic As a part of the CARES Act, the temporary relief from troubled debt restructurings (“TDRs”) provided an option for financial institutions to suspend the GAAP requirements and regulatory determinations for loan modifications related to the COVID-19 pandemic that would otherwise be categorized as a TDR from March 1, 2020, through the earlier of 60 days after the date of the COVID-19 National Emergency comes to an end or December 31, 2020, if the loan was not more than 30 days past due as of December 31, 2019. On April 7, 2020, the federal banking regulators also issued the Interagency Statement to encourage banks to work prudently with borrowers and describe the banking regulators’ interpretation of how accounting rules for TDR apply to certain modifications related to the COVID-19 pandemic. On December 27, 2020, the Economic Aid Act was signed into law, which extended the applicable period of the temporary relief from TDRs under the CARES Act to the earlier of 60 days after the date of the COVID-19 National Emergency comes to an end or January 1, 2022. As of September 30, 2021 and December 31, 2020, total loans under modified terms related to the COVID-19 pandemic were none and $36.1 million, respectively. All loans under modified terms related to the COVID-19 pandemic were accounted for under section 4013 of the CARES Act and not considered TDRs. All types of modifications had initial modification terms of 6-months or less and loans that were granted modifications related to the COVID-19 pandemic in excess of 6 months, on a cumulative basis, were classified as special mention or substandard. In addition, all loans under modified terms related to the COVID-19 pandemic were current and on accrual status as of December 31, 2020; however, all of these loans were monitored on an ongoing basis in accordance with each loan’s covenants and conditions for potential downgrade or change in accrual status. Small Business Administration Paycheck Protection Program The Small Business Administration (“SBA”) launched the Paycheck Protection Program (“PPP”) to provide a direct incentive for small businesses to keep their workers on the payroll in response to the COVID-19 pandemic. The SBA guarantees 100% of the PPP loans made to eligible borrowers, and the loans are eligible to be forgiven if certain conditions are met, at which point the SBA will make payments to the Bank for the forgiven amounts. These loans are included in the commercial and industrial loans portfolio and have an interest rate of 1%. The substantial majority of the SBA PPP loans funded in 2020 in the Company’s portfolio have a maturity of two years. On January 13, 2021, the SBA began accepting applications for second draw PPP loans. During the nine months ended September 30, 2021, the Company had funded 1,153 SBA PPP loans totaling $107.0 million, net of unamortized deferred fees and costs. SBA PPP loans funded in 2021 have a maturity of five years. As of September 30, 2021, the Company had 800 SBA PPP loans totaling $101.9 million, net of unamortized deferred fees and costs, and recognized $145.4 million in forgiveness for 1,992 SBA PPP loans. The Company defers loan origination fees on SBA PPP loans and amortizes these deferred fees and costs without prepayment assumption using the contractual lives of SBA PPP loans. The SBA guarantee on PPP loans cannot be separated from the loan and therefore is not a separate unit of account. The Company considered the SBA guarantee in the allowance for loan losses evaluation and determined that it is not required to reserve an allowance on SBA PPP loans at September 30, 2021 and December 31, 2020. Adopted Accounting Pronouncements During the nine months ended September 30, 2021, there were no significant accounting pronouncements applicable to the Company that became effective. Recent Accounting Pronouncements Not Yet Adopted The following is recently issued accounting pronouncements applicable to the Company that has not yet been adopted: In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13, “Financial Instruments-Credit Losses (Topic 326).” The amendments in this ASU require that entities change the impairment model for most financial assets that are measured at amortized cost and certain other instruments from an incurred loss model to an expected loss model. Under this model, entities will estimate credit losses over the entire contractual term of the instrument from the date of initial recognition of that instrument. It includes financial assets such as loan receivables, held-to-maturity debt securities, net investment in leases that are not accounted for at fair value through net income, and certain off-balance sheet credit exposures. This ASU was effective for public business entities that are SEC filers for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. In 2019, the FASB amended this ASU, which delays the effective date to 2023 for certain SEC filers that are Smaller Reporting Companies, which would apply to the Company. The Company plans to adopt this ASU at the delayed effective date of January 1, 2023.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Accounting Standards Codification (“ASC”) 820, Fair Value Measurements and Disclosures, defines fair value, establishes a framework for measuring fair value including a three-level valuation hierarchy, and expands disclosures about fair value measurements. Fair value is the exchange price that would be received for an asset or paid to transfer a liability (i.e. an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The three-level fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The three levels of inputs that may be used to measure fair value are defined as follows: • Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. • Level 2: Significant observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. • Level 3: Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. Fair value is measured on a recurring basis for certain assets and liabilities in which fair value is the primary basis of accounting. Additionally, fair value is used on a non-recurring basis to evaluate certain assets or liabilities for impairment or for disclosure purposes. Categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The Company records securities available-for-sale at fair value on a recurring basis. Certain other assets, such as loans held-for-sale, impaired loans, servicing assets and other real estate owned (“OREO”) are recorded at fair value on a non-recurring basis. Non-recurring fair value measurements typically involve assets that are periodically evaluated for impairment and for which any impairment is recorded in the period in which the re-measurement is performed. The following is a description of valuation methodologies used for assets and liabilities recorded at fair value: Investment securities : The fair values of securities available-for-sale are determined by obtaining quoted prices on nationally recognized securities exchanges (Level 1) or matrix pricing, which is a mathematical technique used widely in the industry to value debt securities without relying exclusively on quoted prices for specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2). Management reviews the valuation techniques and assumptions used by the provider and determines that the provider uses widely accepted valuation techniques based on observable market inputs appropriate for the type of security being measured. Securities held-to-maturity are not measured at fair value on a recurring basis. Loans held-for-sale : The Company records SBA loans held-for-sale, residential property loans held-for-sale and certain non-residential real estate loans held-for-sale at the lower of cost or fair value, on an aggregate basis. The Company obtains fair values from a third party independent valuation service provider. Loans held-for-sale accounted for at the lower of cost or fair value are considered to be recognized at fair value when they are recorded at below cost, on an aggregate basis, and are classified as Level 2. Impaired loans : Certain collateral-dependent impaired loans are recognized at fair value when they reflect partial write-downs, through charge-offs or specific reserve allowances, that are based on the current appraised or market-quoted value of the underlying collateral. In some cases, the properties for which market quotes or appraised values have been obtained are located in areas where comparable sales data is limited, outdated, or unavailable. Fair value estimates for collateral-dependent impaired loans are obtained from real estate brokers or other third-party consultants, and are classified as Level 3. Other real estate owned : The Company initially records OREO at fair value at the time of foreclosure. Thereafter, OREO is recorded at the lower of cost or fair value based on their subsequent changes in fair value. The fair value of OREO is generally based on recent real estate appraisals adjusted for estimated selling costs. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the appraisers to adjust for differences between the comparable sales and income data available. Such adjustments may be significant and result in a Level 3 classification due to the unobservable inputs used for determining fair value. Only OREO with a valuation allowance are considered to be carried at fair value. Servicing Assets: Servicing assets represent the value associated with servicing loans that have been sold. The fair value for servicing assets is determined through discounted cash flow analysis and utilizes discount rates and prepayment speed assumptions as inputs. All of these assumptions require a significant degree of management estimation and judgment. The fair market valuation is performed on a quarterly basis for servicing assets. Servicing assets are accounted for at the lower of cost or market value and considered to be recognized at fair value when they are recorded at below cost and are classified as Level 3.

Fair value estimates are made at a specific point in time based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the entire holdings of a particular financial instrument. Because no market value exists for a significant portion of the financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature, involve uncertainties and matters of judgment and, therefore, cannot be determined with precision. Changes in assumptions could significantly affect the estimates. Fair value estimates are based on financial instruments both on and off the consolidated balance sheet without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. Additionally, tax consequences related to the realization of the unrealized gains and losses can have a potential effect on fair value estimates and have not been considered in many of the estimates. The following methods and assumptions were used to estimate the fair value of significant financial instruments. Financial assets : The carrying amounts of interest-bearing deposits with other financial institutions and accrued interest receivable are considered to approximate fair value. The fair values of investment securities are generally based on matrix pricing (Level 2). The fair value of loans is estimated based on a discounted cash flow approach under an exit price notion. The fair value reflects the estimated yield that would be negotiated with a willing market participant. Because sale transactions of such loans are not readily observable, as many of the loans have unique risk characteristics, the valuation is based on significant unobservable inputs (Level 3). It is not practical to determine the fair value of Federal Home Loan Bank (“FHLB”) and other restricted stock due to restrictions placed on its transferability. Financial liabilities : The carrying amounts of accrued interest payable are considered to approximate fair value. The fair value of deposits is estimated based on discounted cash flows. The discount rate is derived from the interest rates currently being offered for similar remaining maturities. Non-maturity deposits are estimated based on their historical decaying experiences (Level 3). The fair value of FHLB advances is estimated based on discounted cash flows. The discount rate is derived from the current market rates for borrowings with similar remaining maturities (Level 2). Off-balance-sheet financial instruments : The fair value of commitments to extend credit and standby letters of credit is estimated using the fees currently charged to enter into similar agreements. The fair value of these financial instruments is not material and is excluded from the table below. The following table presents the carrying value and estimated fair values of financial assets and liabilities as of the dates indicated: Carrying Value Fair Value Fair Value Measurements ($ in thousands) Level 1 Level 2 Level 3 September 30, 2021 Financial assets: Interest-bearing deposits in other financial institutions $ 195,285 $ 195,285 $ 195,285 $ — $ — Securities available-for-sale 133,102 133,102 — 133,102 — Loans held-for-sale 29,020 32,003 — 32,003 — Net loans held-for-investment 1,684,071 1,698,852 — — 1,698,852 FHLB and other restricted stock 8,577 N/A N/A N/A N/A Accrued interest receivable 5,515 5,515 7 280 5,228 Financial liabilities: Deposits $ 1,832,666 $ 1,753,463 $ — $ — $ 1,753,463 FHLB advances 10,000 10,142 — 10,142 — Accrued interest payable 745 745 — 1 744 December 31, 2020 Financial assets: Interest-bearing deposits in other financial institutions $ 174,493 $ 174,493 $ 174,493 $ — $ — Securities available-for-sale 120,527 120,527 — 120,527 — Loans held-for-sale 1,979 2,112 — 2,112 — Net loans held-for-investment 1,557,068 1,574,063 — — 1,574,063 FHLB and other restricted stock 8,447 N/A N/A N/A N/A Accrued interest receivable 9,334 9,334 1 322 9,011 Financial liabilities: Deposits $ 1,594,851 $ 1,594,112 $ — $ — $ 1,594,112 FHLB advances 80,000 80,321 — 80,321 — Accrued interest payable 2,226 2,226 — 2 2,224

OTTI is recognized when fair value is below the amortized cost where: (i) an entity has the intent to sell the security; (ii) it is more likely than not that an entity will be required to sell the security before recovery of its amortized cost basis; or (iii) an entity does not expect to recover the entire amortized cost basis of the security. All individual securities in a continuous unrealized loss position for 12 months or more as of September 30, 2021 and December 31, 2020 had an investment grade rating upon purchase. The issuers of these securities have not established any cause for default on these securities and various rating agencies have reaffirmed their long-term investment grade status as of September 30, 2021 and December 31, 2020. These securities have fluctuated in value since their purchase dates as market interest rates fluctuated. The Company does not intend to sell these securities and it is more likely than not that the Company will not be required to sell before the recovery of its amortized cost basis. The Company determined that the investment securities with unrealized losses for twelve months or more are not other-than-temporary impaired, and, therefore, no impairment was recognized during the three and nine months ended September 30, 2021 and 2020.

The Company analyzes loans individually by classifying the loans in regards to credit risk. This analysis typically includes non-homogeneous loans, such as commercial property and commercial and industrial loans, and is performed on an ongoing basis as new information is obtained. The Company uses the following definitions for risk ratings: Pass - Loans classified as pass include non-homogeneous loans not meeting the risk ratings defined below and smaller, homogeneous loans not assessed on an individual basis. Special Mention - Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in the deterioration of repayment prospects for the loan or of the institution’s credit position at some future date. Substandard - Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans classified as substandard have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies In the ordinary course of business, the Company enters into financial commitments to meet the financing needs of its customers. These financial commitments include commitments to extend credit and letters of credit. Those instruments involve to varying degrees, elements of credit, and interest rate risk not recognized in the Company’s consolidated financial statements. As of September 30, 2021 and December 31, 2020, the Company had the following outstanding financial commitments whose contractual amount represents credit risk: September 30, 2021 December 31, 2020 ($ in thousands) Fixed Rate Variable Rate Fixed Rate Variable Rate Unused lines of credit $ 5,852 $ 150,559 $ 6,623 $ 150,247 Unfunded loan commitments 130 33,798 1,752 34,874 Standby letters of credit 3,037 1,431 2,971 1,814 Commercial letters of credit 353 — — — Total $ 9,372 $ 185,788 $ 11,346 $ 186,935 Unfunded loan commitments are generally made for periods of 90 days or less, except for SBA loans that are generally made for periods of 180 days or less. The Company’s exposure to loan loss in the event of nonperformance on commitments to extend credit and standby letters of credit is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments as it does for the loans reflected in the consolidated financial statements. The Company maintained a reserve for off-balance sheet items of $191 thousand and $238 thousand, respectively, at September 30, 2021 and December 31, 2020, in Accrued Interest Payable and Other Liabilities in the Consolidated Balance Sheets. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Since many of the commitments are expected to expire without being drawn upon, the total amounts do not necessarily represent future cash requirements. The Company evaluates each client’s credit worthiness on a case-by-case basis. The amount of collateral obtained if deemed necessary by the Company is based on management’s credit evaluation of the customer. Litigation The Company is involved in various matters of litigation, which have arisen in the ordinary course of business. In the opinion of management, the disposition of pending matters of litigation will not have a material effect on the Company’s consolidated financial statements. COVID-19 Pandemic The ongoing COVID-19 pandemic, and governmental and societal responses thereto, have had a severe impact on global economic and market conditions, including significant disruption of, and volatility in, financial markets; global supply chain disruptions; and the institution of social distancing and shelter-in-place requirements that have resulted in temporary closures of many businesses, lost revenues, and increased unemployment throughout the U.S., but also specifically in California, where most of the Company’s operations and a large majority of its customers are located. These conditions have impacted and may in the future impact its business, results of operations, and financial condition negatively. Network and Data Incident On August 30, 2021, the Bank identified unusual activity on its network, responded promptly to disable the activity, investigate its source and monitor the Bank’s network. The Bank subsequently became aware of claims that it had been the target of a ransomware attack, and on September 7, 2021, determined that an external actor had accessed or acquired certain data on its network. The Bank has been working with third-party forensic investigators to understand the nature and scope of the incident and determine what information may have been accessed and what clients were impacted. The investigation revealed that this incident impacted files containing certain Bank customer information, including in some cases personal information of customers and customers’ employees. The Bank has notified or will notify all individuals identified to date, consistent with applicable laws, whose information may have been impacted. All impacted individuals will be offered free Equifax Complete Premier credit monitoring and identity theft protection services. The Bank has notified law enforcement and appropriate authorities of the incident. The Company continues to monitor and evaluate the data incident for its magnitude and concomitant financial, legal or reputational consequences. To date, such consequences are not material, however the data incident is still recent and notices to affected individuals only recently began. During the three months ended September 30, 2021, expenses associated with the data incident, all of which are included in Other Expense in Consolidated Statements of Income (Unaudited), totaled $100 thousand, which represents the retention amount on its insurance claims. The Company anticipates additional expenses will be incurred in future periods; however, the Company does have a cyber-liability insurance policy that should provide insurance coverage for this incident. To date, no litigation has resulted from the data incident. During its most recent review of disclosure controls and procedures, the Company considered the data incident and concluded that its disclosure controls and procedures were effective. Nevertheless, the Company continues to enhance and update its disclosure controls and procedures, including as part of its efforts to enhance its cybersecurity safeguards and measures. With respect to the data incident, upon discovery the Bank engaged experienced outside counsel and continues to work with its experienced third-party forensics firm to investigate and remediate the matter. The Board of Directors was kept apprised of, and a director with experience in data security participated in, the investigation and remediation efforts. As a result of this incident and based on information known at this date, the Company determined that its disclosure controls and procedures were effective and the data incident did not materially affect, nor was it reasonably likely to affect, the Company’s internal control over financial reporting.

Regulated Operations [Abstract]
Regulatory Matters	Regulatory Matters Under the final rules implementing Basel Committee on Banking Supervision’s capital guidelines for U.S. banks (“Basel III rules”), the Bank must hold a capital conservation buffer of 2.50% above the adequately capitalized risk-based capital ratios. Management believes as of September 30, 2021 and December 31, 2020, the Bank met all capital adequacy requirements to which they are subject to. Based on changes to the Federal Reserve’s definition of a “Small Bank Holding Company” that increased the threshold to $3 billion in assets in August 2018, the Company is not currently subject to separate minimum capital measurements. At such time as the Company reaches the $3 billion asset level, it will again be subject to capital measurements independent of the Bank. For comparison purposes, the Company’s ratios are included in the following discussion as well, all of which would have exceeded the “well-capitalized” level had the Company been subject to separate capital minimums. The Company and the Bank’s capital conservation buffer was 8.32% and 8.01%, respectively, as of September 30, 2021, and 9.22% and 8.95%, respectively, as of December 31, 2020. Unrealized gain or loss on securities available-for-sale is not included in computing regulatory capital. The following table presents the regulatory capital amounts and ratios for the Company and the Bank as of dates indicated: Actual Minimum Capital Requirement To Be Well Capitalized Under Prompt Corrective Provisions ($ in thousands) Amount Ratio Amount Ratio Amount Ratio September 30, 2021 PCB Bancorp Common tier 1 capital (to risk-weighted assets) $ 246,341 15.07 % $ 73,553 4.5 % N/A N/A Total capital (to risk-weighted assets) 266,817 16.32 % 130,762 8.0 % N/A N/A Tier 1 capital (to risk-weighted assets) 246,341 15.07 % 98,071 6.0 % N/A N/A Tier 1 capital (to average assets) 246,341 11.91 % 82,728 4.0 % N/A N/A Pacific City Bank Common tier 1 capital (to risk-weighted assets) $ 241,177 14.76 % $ 73,550 4.5 % $ 106,239 6.5 % Total capital (to risk-weighted assets) 261,652 16.01 % 130,756 8.0 % 163,445 10.0 % Tier 1 capital (to risk-weighted assets) 241,177 14.76 % 98,067 6.0 % 130,756 8.0 % Tier 1 capital (to average assets) 241,177 11.66 % 82,725 4.0 % 103,407 5.0 % December 31, 2020 PCB Bancorp Common tier 1 capital (to risk-weighted assets) $ 231,183 15.97 % $ 65,162 4.5 % N/A N/A Total capital (to risk-weighted assets) 249,391 17.22 % 115,843 8.0 % N/A N/A Tier 1 capital (to risk-weighted assets) 231,183 15.97 % 86,882 6.0 % N/A N/A Tier 1 capital (to average assets) 231,183 11.94 % 77,452 4.0 % N/A N/A Pacific City Bank Common tier 1 capital (to risk-weighted assets) $ 227,268 15.70 % $ 65,160 4.5 % $ 94,120 6.5 % Total capital (to risk-weighted assets) 245,474 16.95 % 115,840 8.0 % 144,800 10.0 % Tier 1 capital (to risk-weighted assets) 227,268 15.70 % 86,880 6.0 % 115,840 8.0 % Tier 1 capital (to average assets) 227,268 11.74 % 77,450 4.0 % 96,813 5.0 % The California Financial Code provides that a bank may not make a cash distribution to its shareholders in excess of the lesser of the bank’s undivided profits or the bank’s net income for its last three fiscal years less the amount of any distribution made to the bank’s shareholder during the same period. As a California corporation, the Company is subject to the limitations of California law, which allows a corporation to distribute cash or property to shareholders, including a dividend or repurchase or redemption of shares, if the corporation meets either a retained earnings test or a balance sheet test. Under the retained earnings test, the Company may make a distribution from retained earnings to the extent that its retained earnings exceed the sum of (a) the amount of the distribution plus (b) the amount, if any, of dividends in arrears on shares with preferential dividend rights. Under the balance sheet test, the Company may also make a distribution if, immediately after the distribution, the value of its assets equals or exceeds the sum of (a) its total liabilities plus (b) the liquidation preference of any shares which have a preference upon dissolution over the rights of shareholders receiving the distribution. Indebtedness is not considered a liability if the terms of such indebtedness provide that payment of principal and interest thereon are to be made only if, and to the extent that, a distribution to shareholders could be made under the balance sheet test.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited interim consolidated financial statements have been prepared pursuant to Article 10 of SEC Regulation S-X and other SEC rules and regulations for reporting on the Quarterly Report on Form 10-Q. Accordingly, certain disclosures required by U.S. generally accepted accounting principles (“GAAP”) are not included herein. These interim statements should be read in conjunction with the audited consolidated financial statements and notes included in the Annual Report on Form 10-K for the year ended December 31, 2020 filed by the Company with the SEC. The December 31, 2020 balance sheet presented herein has been derived from the audited financial statements included in the Annual Report on Form 10-K for the year ended December 31, 2020 filed with the SEC, but does not include all of the disclosures required by GAAP for complete financial statements. In the opinion of management of the Company, the accompanying unaudited interim consolidated financial statements reflect all of the adjustments (consisting of normal recurring adjustments) necessary for a fair presentation of the consolidated financial condition and consolidated results of operations as of the dates and for the periods presented. Certain reclassifications have been made in the prior period financial statements to conform to the current period presentation. The results of operations for the three and nine months ended September 30, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021. Principles of Consolidation The consolidated financial statements include the accounts of PCB Bancorp and its wholly owned subsidiary as of September 30, 2021 and December 31, 2020, and for the three and nine months ended September 30, 2021 and 2020. Significant inter-company accounts and transactions have been eliminated in consolidation. Unless the context requires otherwise, all references to the Company include its wholly owned subsidiary. Significant Accounting Policies The accounting and reporting policies of the Company are based upon GAAP and conform to predominant practices within the banking industry. The Company has not made any significant changes in its critical accounting policies from those disclosed in its Annual Report on Form 10-K for the year ended December 31, 2020 filed with the SEC.
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of PCB Bancorp and its wholly owned subsidiary as of September 30, 2021 and December 31, 2020, and for the three and nine months ended September 30, 2021 and 2020. Significant inter-company accounts and transactions have been eliminated in consolidation. Unless the context requires otherwise, all references to the Company include its wholly owned subsidiary.
Use of Estimates in the Preparation of Financial Statements	Use of Estimates in the Preparation of Financial Statements The preparation of the consolidated financial statements in conformity with 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 revenues and expenses during the reporting period. These estimates are subject to change and such change could have a material effect on the consolidated financial statements. Actual results may differ from those estimates.
Small Business Administration Paycheck Protection Program	Small Business Administration Paycheck Protection Program The Small Business Administration (“SBA”) launched the Paycheck Protection Program (“PPP”) to provide a direct incentive for small businesses to keep their workers on the payroll in response to the COVID-19 pandemic. The SBA guarantees 100% of the PPP loans made to eligible borrowers, and the loans are eligible to be forgiven if certain conditions are met, at which point the SBA will make payments to the Bank for the forgiven amounts. These loans are included in the commercial and industrial loans portfolio and have an interest rate of 1%. The substantial majority of the SBA PPP loans funded in 2020 in the Company’s portfolio have a maturity of two years. On January 13, 2021, the SBA began accepting applications for second draw PPP loans. During the nine months ended September 30, 2021, the Company had funded 1,153 SBA PPP loans totaling $107.0 million, net of unamortized deferred fees and costs. SBA PPP loans funded in 2021 have a maturity of five years. As of September 30, 2021, the Company had 800 SBA PPP loans totaling $101.9 million, net of unamortized deferred fees and costs, and recognized $145.4 million in forgiveness for 1,992 SBA PPP loans. The Company defers loan origination fees on SBA PPP loans and amortizes these deferred fees and costs without prepayment assumption using the contractual lives of SBA PPP loans. The SBA guarantee on PPP loans cannot be separated from the loan and therefore is not a separate unit of account. The Company considered the SBA guarantee in the allowance for loan losses evaluation and determined that it is not required to reserve an allowance on SBA PPP loans at September 30, 2021 and December 31, 2020.
Adopted Accounting Pronouncements and Recent Accounting Pronouncements Not Yet Adopted	Adopted Accounting Pronouncements During the nine months ended September 30, 2021, there were no significant accounting pronouncements applicable to the Company that became effective. Recent Accounting Pronouncements Not Yet Adopted The following is recently issued accounting pronouncements applicable to the Company that has not yet been adopted: In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13, “Financial Instruments-Credit Losses (Topic 326).” The amendments in this ASU require that entities change the impairment model for most financial assets that are measured at amortized cost and certain other instruments from an incurred loss model to an expected loss model. Under this model, entities will estimate credit losses over the entire contractual term of the instrument from the date of initial recognition of that instrument. It includes financial assets such as loan receivables, held-to-maturity debt securities, net investment in leases that are not accounted for at fair value through net income, and certain off-balance sheet credit exposures. This ASU was effective for public business entities that are SEC filers for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. In 2019, the FASB amended this ASU, which delays the effective date to 2023 for certain SEC filers that are Smaller Reporting Companies, which would apply to the Company. The Company plans to adopt this ASU at the delayed effective date of January 1, 2023.
