Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Operations	1. NATURE OF OPERATIONS Organization California BanCorp (the “Company”), a California corporation headquartered in Oakland, California, is the bank holding company for its wholly-owned subsidiary California Bank of Commerce (the “Bank”), which offers a broad range of commercial banking services to closely held businesses and professionals located throughout Northern California. The Bank has a full service branch located in Contra Costa County and 4 loan production offices located in Alameda County, Contra Costa County, Sacramento County, and Santa Clara County. Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q 10-K The results of operations for the three and nine months ended September 30, 2022 are not necessarily indicative of the results of operations that may be expected for any other interim period or for the year ending December 31, 2022. The Company’s accounting and reporting policies conform to GAAP and to general practices within the banking industry. Subsequent Events Management has reviewed all events through the date the unaudited consolidated financial statements were filed with the SEC and concluded that no event required any adjustment to the balances presented. Use of Estimates Management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the unaudited consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates and assumptions affect the amounts reported in the unaudited consolidated financial statements and the disclosures provided, and actual results could differ. The estimates utilized to determine the appropriate allowance for loan losses at September 30, 2022 may be materially different from actual results due to the ongoing COVID-19 Reclassifications Certain prior balances in the unaudited consolidated financial statements may have been reclassified to conform to current year presentation. These reclassifications had no effect on prior year net income or shareholders’ equity. Business Impact of COVID-19 The COVID-19 COVID-19 Although the impact of COVID-19 Goodwill Goodwill impairment exists when a reporting unit’s carrying value exceeds its fair value, which is determined through a qualitative assessment whether it is more likely than not that the fair value of equity of the reporting unit exceeds the carrying value (“Step Zero”). The Company completed an impairment analysis of goodwill as of September 30, 2022 and determined there was no impairment. As part of the Company’s qualitative assessment of goodwill impairment, management considered COVID-19 Earnings Per Share (“EPS”) Basic earnings per common share represents the amount of earnings for the period available to each share of common stock outstanding during the reporting period. Basic EPS is computed based upon net income divided by the weighted average number of common shares outstanding during the period. In determining the weighted average number of shares outstanding, vested restricted stock units are included. Diluted EPS represents the amount of earnings for the period available to each share of common stock outstanding including common stock that would have been outstanding assuming the issuance of common shares for all dilutive potential common shares outstanding during each reporting period. Diluted EPS is computed based upon net income divided by the weighted average number of common shares outstanding during each period, adjusted for the effect of dilutive potential common shares, such as restricted stock awards and units, calculated using the treasury stock method.

Management believes that changes in the market value since purchase are primarily attributable to changes in interest rates and relative illiquidity. Because the Company does not intend to sell and is unlikely to be required to sell until a recovery of fair value, which may be at maturity, the Company did not consider those investments to be other-than-temporarily impaired at September 30, 2022 and December 31, 2021, respectively.

COMMITMENTS AND CONTINGENT LIABILITIES Financial Instruments with Off-Balance The Company is a party to financial instruments with off-balance 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. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since some of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer’s creditworthiness on a case-by-case At September 30, 2022 and December 31, 2021, the Company had outstanding unfunded commitments for loans of approximately $626.8 million and $620.0 million, respectively.

Fair Value Measurements

Fair Value Measurements	9 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	6. FAIR VALUE MEASUREMENTS Fair Value Hierarchy The Company groups its assets and liabilities measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. Valuations within these levels are based upon: Level 1 - Quoted market prices for identical instruments traded in active exchange markets. Level 2 - Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable or can be corroborated by observable market data. Level 3 - Model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect the Company’s estimates of assumptions that market participants would use on pricing the asset or liability. Valuation techniques include management judgment and estimation which may be significant. Management monitors the availability of observable market data to assess the appropriate classification of financial instruments within the fair value hierarchy. Changes in economic conditions or model-based valuation techniques may require the transfer of financial instruments from one fair value level to another. In such instances, the transfer is reported at the beginning of the reporting period. Management evaluates the significance of transfers between levels based upon the nature of the financial instrument and size of the transfer relative to total assets, total liabilities or total earnings. Impaired loans - Impaired loans are evaluated on a quarterly basis for additional impairment and adjusted accordingly. The fair value of impaired loans with specific allocations of the allowance for loan losses that are secured by real property is generally based on recent real estate appraisals. 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 independent appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are usually significant and typically result in a Level 3 classification of the inputs for determining fair value. The methods utilized to estimate the fair value of impaired loans do not necessarily represent an exit price. Deposits - The fair values disclosed for demand deposits (e.g., interest and non-interest FHLB Advances - FHLB Advances are included in Other Borrowings. Fair values for FHLB Advances are estimated using discounted cash flow analyses using interest rates offered at each reporting date by correspondent banks for advances with similar maturities resulting in Level 3 classification. Paycheck Protection Program Liquidity Facility (PPPLF) - The fair value of PPPLF is estimated using a discounted cash flow based on the remaining contractual term and current rates at which similar advances would be obtained resulting in Level 3 classification. Senior Notes - Fair values for senior notes are estimated using a discounted cash flow calculation based on current rates for similar types of debt which may be unobservable, and considering recent trading activity of similar instruments in market which can be inactive and accordingly are classified within in the Level 3 classification. Junior Subordinated Debt Securities - Fair values for subordinated debt are calculated based on its terms and were discounted to the date of the valuation to calculate the fair value on the debt. A market rate based on recent debt offering by peer bank was used to discount cash flow until reprice date and subsequently cash flow were discounted at Prime plus 2% for its security. These assumptions which may be unobservable, and considering recent trading activity of similar instruments in market which can be inactive and accordingly are classified within the Level 3 classification. Accrued Interest Receivable - The carrying amounts of accrued interest receivable approximate fair value resulting in a Level 2 classification for accrued interest receivable on investment securities and a Level 3 classification for accrued interest receivable on loans since investment securities are generally classified using Level 2 inputs and loans are generally classified using Level 3 inputs. Accrued Interest Payable - The carrying amounts of accrued interest payable approximate fair value resulting in a Level 2 classification, since accrued interest payable is from deposits that are generally classified using Level 2 inputs. Off Balance Sheet Instruments - Fair values for off-balance Assets Recorded at Fair Value on a Recurring Basis The Company is required or permitted to record the following assets at fair value on a recurring basis as of September 30, 2022 and December 31, 2021.

In addition, the tax ramifications related to the realization of unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in any of these estimates. The methods and assumptions used to estimate fair values are described as follows: Cash and Due from banks - The carrying amounts of cash and short-term instruments approximate fair values and are classified as Level 1. Investment Securities - Since quoted prices are generally not available for identical securities, fair values are calculated based on market prices of similar securities on similar dates, resulting in Level 2 classification. For securities where market prices of similar securities are not available, fair values are calculated using discounted cash flows or other market indicators, resulting in Level 3 classification. FHLB, IBFC, PCBB Stock - It is not practical to determine the fair value of these correspondent bank stocks due to restrictions placed on their transferability. Loans - Fair values of loans for September 30, 2022 and December 31, 2021 are estimated on an exit price basis with contractual cash flow, prepayments, discount spreads, credit loss and liquidity premium assumptions. Loans with similar characteristics such as prepayment rates, terms and rate indexed are aggregated for purposes of the calculations. The fair values of loans are classified as Level 3.
