Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Organization and Nature of Operations: Level One Bancorp, Inc. (the "Company") was organized to become a bank holding company to establish and operate a new bank, Level One Bank (the "Bank") in Farmington Hills, Michigan. The organization process began in June 2006 and the Company was incorporated on July 17, 2006 under Michigan law. The Bank began operations on October 5, 2007. Level One Bank is a Michigan banking corporation with depository accounts insured by the Deposit Insurance Fund of the Federal Deposit Insurance Corporation (the "FDIC"). The Bank provides a wide range of business and consumer financial services in the greater Farmington Hills, Novi, Northville, Birmingham, Ferndale, Sterling Heights, Bloomfield Township, Detroit and Grand Rapids areas. Its primary deposit products are checking, interest-bearing demand, savings, and term certificate accounts, and its primary lending products are commercial, residential mortgage, and installment loans. Substantially all loans are secured by specific items of collateral including business assets, consumer assets, and commercial and residential real estate. Commercial loans are expected to be repaid from cash flow from operations of businesses. Other financial instruments, which potentially represent concentrations of credit risk, include federal funds sold. On July 9, 2017, the Company formed a new subsidiary, Hamilton Court Insurance Company ("Hamilton Court"), which is a wholly owned insurance subsidiary of the Company that provides property and casualty insurance coverage to the Company and the Bank, and reinsurance to ten other third party insurance captives for which insurance may not be currently available or economically feasible in the insurance marketplace. The Hamilton Court insurance subsidiary was designed to insure the risks of the Company and the Bank by providing additional insurance coverage for deductibles, excess limits and uninsured exposures. Hamilton Court is domiciled in Nevada. On April 24, 2018, the Company sold 1,150,765 shares of common stock in its initial public offering, including 180,000 shares of common stock pursuant to the exercise in full by the underwriters of their option to purchase additional shares. The aggregate offering price for the shares sold by the Company was $32.2 million , and after deducting $2.1 million of underwriting discounts and $1.1 million of offering expenses paid to third parties, the Company received total net proceeds of $29.0 million from the initial public offering. In addition, certain selling shareholders participated in the offering and sold an aggregate of 229,235 shares of our common stock at an aggregate offering price of $6.4 million . The Company did not receive any proceeds from the sales of shares by the selling shareholders. Basis of Presentation and Principles of Consolidation: The accompanying unaudited consolidated financial statements and notes thereto of the Company have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”) for Form 10-Q and conform to practices within the banking industry and include all of the information and disclosures required by accounting principles generally accepted in the United States of America (“GAAP”) for interim financial reporting. The accompanying unaudited consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments), which are necessary for a fair presentation of financial results for the interim periods presented. The results of operations for the interim periods are not necessarily indicative of the results for the full year. These interim unaudited financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto as of and for the year ended December 31, 2017, included in our registration statement on Form S-1, as amended, filed with the SEC on April 12, 2018 and declared effective on April 19, 2018. The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, the Bank and Hamilton Court, after elimination of significant intercompany transactions and accounts. Use of Estimates: To prepare financial statements in conformity with U.S. generally accepted accounting principles ("GAAP"), management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided, therefore future results could differ. Estimates that are particularly susceptible to significant change include the determination of the allowance for loan losses, expected cash flows from acquired loans, fair value amounts related to business combinations, income taxes, goodwill impairment and those assets and liabilities that require fair value measurement. Emerging Growth Company Status: We are an "emerging growth company," as defined in the Jumpstart Our Business Startups Act of 2012, or the JOBS Act. Section 107 of the JOBS Act provides that an emerging growth company can take advantage of the extended transition period when complying with new or revised accounting standards. In other words, an emerging growth company can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have elected to take advantage of this extended transition period, which means these financial statements, as well as financial statements we file in the future for as long as we remain an emerging growth company, will be subject to all new or revised accounting standards generally applicable to private companies. Recent Accounting Standards: Revenue Recognition In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-09 "Revenue from Contracts with Customers (Topic 606)," which provides a framework for revenue recognition that replaces the existing industry and transaction specific requirements under the existing standards. ASU 2014-09 requires an entity to apply a five-step model to determine when to recognize revenue and at what amount. The model specifies that revenue should be recognized when (or as) an entity transfers control of goods or services to a customer at the amount in which the entity expects to be entitled. Depending on whether certain criteria are met, revenue should be recognized either over time, in a manner that depicts the entity's performance, or at a point in time, when control of the goods or services are transferred to the customer. The amendments of ASU 2014-09 may be applied either retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying ASU 2014-09 recognized at the date of initial application. The guidance will be effective for the Company for the fiscal year ended after December 31, 2018 . The Company plans to adopt these amendments during the first quarter of 2019. The Company is continuing to evaluate the impact ASU 2014-09 will have on our consolidated financial statements. Based on this evaluation to date, management has determined that the majority of the revenues earned by the Company are not within the scope of ASU 2014-09, and that some of the revenue streams that have been identified as being in scope would include service charges and interchange fees. Management will continue to evaluate the impact the adoption of ASU 2014-09 will have on our consolidated financial statements, focusing on noninterest income sources within the scope of ASU 2014-09 as well as new disclosures required by these amendments; however, the adoption of ASU 2014-09 is not expected to have a material impact on the Company's consolidated financial statements but is expected to result in additional disclosures. Financial Instruments In January 2016, the FASB issued ASU No. 2016-01, "Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities," to improve the accounting for financial instruments. This ASU requires equity investments with readily determinable fair values to be measured at fair value with changes recognized in net income regardless of classification. For equity investments without a readily determinable fair value, the value of the investment would be measured at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer instead of fair value, unless a qualitative assessment indicates impairment. Additionally, this ASU requires the separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements, as well as the required use of exit pricing when measuring the fair value of financial instruments for disclosure purposes. This guidance is effective for fiscal years beginning after December 15, 2018, and interim periods within fiscal years beginning after December 15, 2019, and is to be applied prospectively with a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. Management is in the planning stages of developing processes and procedures to comply with the disclosures requirements of this ASU, which could impact the disclosures the Company makes related to fair value of its financial instruments. The Company is planning to adopt this new guidance within the time frames stated above. Leases In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)," to improve transparency and comparability across entities regarding leasing arrangements. This ASU requires the recognition of a separate lease liability representing the required discounted lease payments over the lease term and a separate lease asset representing the right to use the underlying asset during the same lease term. Additionally, this ASU provides clarification regarding the identification of certain components of contracts that would represent a lease as well as requires additional disclosures to the notes of the financial statements. This guidance is effective for fiscal years beginning after December 15, 2019, and interim periods within fiscal years beginning after December 15, 2020, and is to be applied under a modified retrospective approach. The Company is currently evaluating the impact of adopting this new guidance on the consolidated financial statements. Additionally, the Company does not expect to significantly change operating lease agreements prior to adoption. The Company is planning to adopt this new guidance within the time frames stated above. Allowance for Credit Losses In June 2016, the FASB issued ASU No. 2016-13, "Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments," to replace the current incurred loss methodology for recognizing credit losses, which delays recognition until it is probable a loss has been incurred, with a methodology that reflects an estimate of all expected credit losses and considers additional reasonable and supportable forecasted information when determining credit loss estimates. This impacts the calculation of the allowance for credit losses for all financial assets measured under the amortized cost basis, including PCI loans at the time of and subsequent to acquisition. Additionally, credit losses related to available-for-sale debt securities would be recorded through the allowance for credit losses and not as a direct adjustment to the amortized cost of the securities. This guidance is effective for fiscal years beginning after December 15, 2020, including interim periods after those fiscal years, and is to be applied under a modified retrospective approach. The Company is currently evaluating the impact of adopting this new guidance on the consolidated financial statements as well as the impact on current systems and processes. At this time, the Company is reviewing potential methodologies for estimating expected credit losses using reasonable and supportable forecast information as well as has identified certain data and system requirements. Once adopted, we expect our allowance for loan losses to increase through a one-time adjustment to retained earnings; however, until our evaluation is complete, the estimated increase in allowance will be unknown. The Company is planning to adopt this new guidance within the time frames stated above. Investment Securities The Company elected to early adopt ASU No. 2017-08, "Receivables-Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities ("ASU 2017-08")" during the first quarter of 2017. The guidance in ASU 2017-08 shortens the amortization period for certain callable debt securities that are held at a premium to the earliest call date. Debt securities held at a discount will continue to be amortized as a yield adjustment over the life of the instrument. The early adoption of ASU 2017-08 in the first quarter of 2017 did not have a material impact on the Company's Consolidated Financial Statements. Income Taxes - Tax Cuts and Jobs Act In February 2018, the FASB issued ASU No. 2018-02, "Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (Topic 220)," which allows an entity to elect a reclassification from accumulated other comprehensive income (AOCI) to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act ("TCJA"). The amount of that reclassification should include the effect of changes of tax rate on the deferred tax amount, any related valuation allowance and other income tax effects on the items in AOCI. In addition, the ASU requires that an entity state if an election to reclassify the tax effects to retained earnings is made, along with a description of other income tax effects that are reclassified from AOCI. This guidance is effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years, with early adoption permitted. The Company early adopted the ASU and reclassified $168 thousand from retained earnings to AOCI during the first quarter of 2018. In May 2018, the FASB issued an update ASU No. 2018-05, "Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulleting No. 118," regarding the accounting implications of the recently issued TCJA. The update clarifies that in a company's financial statements that include the reporting period in which the TCJA was enacted, a company must first reflect the income tax effects of the TCJA in which the accounting under GAAP is complete. These amounts would not be provisional amounts. The company would also report provisional amounts for those specific income tax effects for which the accounting under GAAP will be incomplete but for which a reasonable estimate can be determined. This accounting update is effective immediately. The Company believes its accounting for the income tax effects of the TCJA is complete. Technical corrections or other forthcoming guidance could change how we interpret provisions of the TCJA, which may impact our effective tax rate and could affect our deferred tax assets, tax positions and/or our tax liabilities.

This applies to all loan modifications except for modifications to loans accounted for in pools under ASC 310-30, which are not subject to TDR accounting/classification. For loans excluded from ASC 310-30 accounting, a modification is considered a TDR when a borrower is experiencing financial difficulties and the Company grants a concession to the borrower. For loans accounted for individually under ASC 310-30, a modification is considered a TDR when a borrower is experiencing financial difficulties and the effective yield after the modification is less than the effective yield at the time the loan was acquired or less than the effective yield of any re-estimation of cash flows subsequent to acquisition in association with consideration of qualitative factors included within ASC 310-40. All TDRs are considered impaired loans. The nature and extent of impairment of TDRs, including those which have experienced a subsequent default, is considered in the determination of an appropriate level of allowance for loan losses. As of March 31, 2018 and December 31, 2017 , the Company had a recorded investment in troubled debt restructurings of $10.1 million and $7.6 million, respectively. The Company has allocated a specific reserve of $999 thousand for those loans at March 31, 2018 and a specific reserve of $975 thousand for those loans at December 31, 2017 . The Company has not committed to lend additional amounts to borrowers whose loans have been modified. As of March 31, 2018 , there were $7.7 million of nonperforming TDRs and $2.4 million of performing TDRs included in impaired loans. As of December 31, 2017 , there were $6.4 million of nonperforming TDRs and $1.2 million of performing TDRs included in impaired loans. All TDRs are considered impaired loans in the calendar year of their restructuring. A loan that has been modified will return to performing status if it satisfies a six-month performance requirement; however, it will continue to be reported as a TDR and considered impaired. The following table presents the recorded investment of loans modified in TDRs during the three months ended March 31, 2018 and March 31, 2017 , by type of concession granted. In cases where more than one type of concession was granted, the loans were categorized based on the most significant concession.

The Company analyzes loans individually by classifying the loans as to credit risk. This analysis includes non-homogeneous loans, such as commercial and industrial and commercial real estate loans. This analysis is performed on an annual basis. The Company uses the following definitions for risk ratings: Pass. Higher quality loans that do not fit any of the other categories described below. This category includes loans risk rated with the following ratings: cash/stock secured, excellent credit risk, superior credit risk, good credit risk, satisfactory credit risk, and marginal credit risk. 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 deterioration of the 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 so classified 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. Doubtful. Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. Based on the most recent analysis performed, the risk category of loans by class of loans was as follows: (Dollars in thousands) Pass Special Mention Substandard Doubtful Total March 31, 2018 Commercial real estate $ 516,110 $ 8,837 $ 7,628 $ 47 $ 532,622 Commercial and industrial 354,269 6,033 11,157 5 371,464 Total $ 870,379 $ 14,870 $ 18,785 $ 52 $ 904,086 December 31, 2017 Commercial real estate $ 492,731 $ 10,664 $ 8,323 $ 44 $ 511,762 Commercial and industrial 361,740 5,945 9,963 38 377,686 Total $ 854,471 $ 16,609 $ 18,286 $ 82 $ 889,448 For residential real estate loans and consumer loans, the Company evaluates credit quality based on the aging status of the loan and by payment activity. Residential real estate loans and consumer loans are considered nonperforming if 90 days or more past due. Consumer loan types are continuously monitored for changes in delinquency trends and other asset quality indicators.

"Adjustments to accretable yield" represents the net amount of accretable yield added or removed as a result of the semi-annual re-estimation of expected cash flows. For the period ended March 31, 2018 and December 31, 2017 , respectively, allowance for loans losses on PCI loans decreased by $3 thousand and increased by $234 thousand. OFF-BALANCE SHEET ACTIVITIES In the normal course of business, the Company offers a variety of financial instruments with off-balance sheet risk to meet the financing needs of its customers. These financial instruments include outstanding commitments to extend credit, credit lines, commercial letters of credit and standby letters of credit. These are agreements to provide credit, as long as conditions established in the contract are met, and usually have expiration dates. Commitments may expire without being used. Off-balance sheet risk to credit loss exists up to the face amount of these instruments, although material losses are not anticipated. The same credit policies used for loans are used to make such commitments, including obtaining collateral at exercise of the commitment. A summary of the contractual amounts of the Company's exposure to off-balance sheet risk is as follows: March 31, 2018 December 31, 2017 (Dollars in thousands) Fixed Variable Fixed Variable Commitments to make loans $ 7,893 $ 5,243 $ 5,041 $ 8,837 Unused lines of credit 9,892 195,615 12,407 189,787 Unused standby letters of credit 2,409 240 3,584 1,411 Commitments to make loans are generally made for periods of 90 days or less. The fixed rate loan commitments have interest rates ranging from 4.75% to 6.15% and maturities ranging from 1 to 10 years.

Allowance

Receivables [Abstract]
Allowance	ALLOWANCE An allowance for loan losses is maintained to absorb losses from the loan portfolio. The allowance for loan losses is based on management's continuing valuation of the risk characteristics and credit quality of the loan portfolio, assessment of current economic conditions, diversification and size of the portfolio, adequacy of collateral, past and anticipated loss experience, and the amount of nonperforming loans. The Company established an allowance for loan losses associated with PCI loans (accounted for under ASC 310-30) based on credit deterioration subsequent to the acquisition date. As of March 31, 2018 , the Company had six PCI loan pools and 14 non-pooled PCI loans. The Company re-estimates cash flows expected to be collected for purchased credit impaired loans on a semi-annual basis, with any decline in expected cash flows recorded as provision for loan losses on a discounted basis during the period. For any increases in cash flows expected to be collected, the Company adjusts the amount of accretable yield recognized on a prospective basis over the loan's remaining life. For loans not accounted for under ASC 310-30, the Company individually evaluates certain impaired loans on a quarterly basis and establishes specific allowances for such loans, if required. A loan is considered impaired when it is probable that interest or principal payments will not be made in accordance with the contractual terms of the loan agreement. Consistent with this definition, all loans for which the accrual of interest has been discontinued (nonaccrual loans) and all TDRs are considered impaired. The Company individually evaluates nonaccrual loans with book balances of $250 thousand or more, all loans whose terms have been modified in a TDR, and certain other loans. The threshold for individual evaluation is revised on an infrequent basis, generally when economic circumstances change significantly. Specific allowances for impaired loans are estimated using one of several methods, including the estimated fair value of underlying collateral, observable market value of similar debt or discounted expected future cash flows. All other impaired loans are individually evaluated by identifying its risk characteristics and applying the standard reserve factor for the corresponding loan pool. Loans which do not meet the criteria to be individually evaluated are evaluated in homogeneous pools of loans with similar risk characteristics. Business loans are assigned to pools based on the Company's internal risk rating system. Internal risk ratings are assigned to each business loan at the time of approval and are subjected to subsequent periodic reviews by the Company's senior management, generally at least annually or more frequently upon the occurrence of a circumstance that affects the credit risk of the loan. For business loans not individually evaluated, losses inherent to the pool are estimated by applying standard reserve factors to outstanding principal balances. The allowance for loans not individually evaluated is determined by applying estimated loss rates to various pools of loans within the portfolios with similar risk characteristics. Estimated loss rates for all pools are updated quarterly, incorporating quantitative and qualitative factors such as recent charge-off experience, current economic conditions and trends, changes in collateral values of properties securing loans (using index-based estimates), and trends with respect to past due and nonaccrual amounts. Loans acquired in business combinations are initially recorded at fair value, which includes an estimate of credit losses expected to be realized over the remaining lives of the loans, and therefore no corresponding allowance for loan losses is recorded for these loans at acquisition. Methods utilized to estimate any subsequently required allowance for loan losses for acquired loans not deemed credit-impaired at acquisition are similar to originated loans; however, the estimate of loss is based on the unpaid principal balance less any remaining purchase discount.

Goodwill was $9.4 million at both March 31, 2018 and December 31, 2017 . Goodwill is not amortized but is evaluated at least annually for impairment. The Company's most recent annual goodwill impairment review performed as of September 30, 2017 did not indicate that an impairment of goodwill existed. The Company also determined that no triggering events have occurred that indicated impairment from the most recent valuation date through March 31, 2018 and that the Company's goodwill was not impaired at March 31, 2018 . There was no change in goodwill for the three months ended March 31, 2018 and year ended December 31, 2017 . Acquired Intangible Assets : The Company has recorded core deposit intangibles ("CDIs") associated with each of its acquisitions. CDIs are amortized on an accelerated basis over their estimated useful lives.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock Based Compensation	STOCK BASED COMPENSATION 2007 Stock Option Plan On January 16, 2008, the shareholders of the Company, by majority vote, approved the Level One Bancorp, Inc. 2007 Stock Option Plan (the "Stock Option Plan"). The Stock Option Plan was intended to promote equity ownership of the Company by (i) selected officers and employees of the Company and the Bank; (ii) directors of the Company and the Bank; and (iii) the organizers. Such ownership was intended to promote the proprietary interest of the individuals to whom stock options will be granted ("Optionees"), to attract and retain qualified officers, employees and directors, and to further align the interests of Optionees with the interests of the Company's shareholders. The Company's Board of Directors had reserved (with consent of the Company's shareholders) 630,265 shares of common stock for issuance under the Stock Option Plan. During the three months ended March 31, 2018 , the Company granted 30,000 stock options. No options were granted during the three months ended March 31, 2017. The term of the options is ten years and options vest over three years , one-third each year. The Company will use authorized but unissued shares to satisfy share option exercises. The fair value of each option award is estimated on the date of grant using a closed form option valuation (Black-Scholes) model. Expected volatilities are based on historical volatilities of the Company's common stock, which is not actively traded. The Company expects all awards will vest. The expected term of options granted represents the period of time that options granted are expected to be outstanding, which takes into account that the options are not transferable. The risk-free interest rate for the expected term of the option is based on the U.S. Treasury yield curve in effect at the time of the grant. The fair value of the stock options granted was determined using the following weighted-average assumptions as of grant date: March 31, 2018 Risk Free Interest Rate 2.83% Expected Term (years) 7.0 Expected Volatility 0.04% Dividend Yield —% Weighted average fair value of options granted $4.46 The employee stock option activity for the period ended March 31, 2018 is summarized below: Shares Weighted Average Exercise Price Weighted Average Remaining Contractual Term Aggregate Intrinsic Value Outstanding at 1/1/2018 484,147 $ 13.96 4.7 $ 5,247 Granted 30,000 24.80 Exercised 118,944 10.03 Forfeited 9,885 10.00 Outstanding at 3/31/2018 385,318 $ 16.12 6.5 $ 3,420 Exercisable at 3/31/2018 292,808 $ 14.58 5.9 $ 3,052 Share-based compensation expense charged against income was $42 thousand and $44 thousand for the three months ended March 31, 2018 and 2017, respectively. As of March 31, 2018 , there was $218 thousand of total unrecognized compensation cost related to stock options granted under the Stock Option Plan. The cost is expected to be recognized over a weighted-average period of 1.43 years . 2014 Equity Incentive Plan Under the 2014 Equity Incentive Plan, the Company could grant restricted stock awards to its directors ("Plan A") and employees ("Plan B"). The Company had reserved 150,000 shares of common stock for issuance under the 2014 Equity Incentive Plan. Restricted stock awards are participating shares that vest upon completion of future service requirements. If an individual awarded restricted stock awards terminates employment prior to the end of the vesting period, the unvested portion of the stock award is forfeited. The fair value of these awards is equal to the fair value of the stock as of the issuance date and determined by using an independent valuation. The Company recognizes stock-based compensation expense for these awards over the vesting period, using the straight-line method, based upon the number of shares of restricted stock ultimately expected to vest. For Plan A, restricted stock awards granted during the three months ended March 31, 2018 and 2017 were 19,670 and 21,400 , respectively and fully vest after 3 years. For Plan B, restricted stock awards granted during the three months ended March 31, 2018 and 2017 were 10,601 and 11,577 , respectively and vested one fourth at quarter ends. A summary of changes in the Company's nonvested shares for the period ended March 31, 2018 is as follows: Nonvested Shares Shares Weighted Average Grant-Date Fair Value Nonvested at 1/1/2018 30,150 $ 22.03 Granted 30,271 24.80 Vested 2,648 24.80 Nonvested at 3/31/2018 57,773 $ 23.35 Total expense for restricted stock awards totaled $141 thousand and $78 thousand for the three months ended March 31, 2018 and 2017, respectively. As of March 31, 2018, there was $1.0 million of total unrecognized compensation cost related to nonvested shares granted under the 2014 Equity Incentive Plan. The cost is expected to be recognized over a weighted average period of 2.03 years . The total fair value of shares vested during the three months ended March 31, 2018 , was $66 thousand . 2018 Equity Incentive Plan On March 15, 2018, the Company’s Board of Directors approved the 2018 Equity Incentive Compensation Plan ("2018 Plan"). The 2018 Plan became effective upon shareholder approval at the annual shareholders meeting held on April 17, 2018. Under the 2018 Plan, the Company can grant incentive and non-qualified stock options, stock awards, stock appreciation rights, and other incentive awards to directors and employees of, and certain service providers to, the Company and its subsidiaries. The Company has reserved 250,000 shares of common stock for issuance under the 2018 Plan. Once the 2018 Plan became effective, no further awards may be granted from the Stock Option Plan or the 2014 Equity Incentive Plan. However, any outstanding equity award granted under the Stock Option Plan or the 2014 Equity Incentive Plan will remain subject to the terms of such plans until the time it is no longer outstanding.

Fair Value Disclosures [Abstract]
Off-Balance Sheet Activities	FAIR VALUE Fair value is the exchange price that would be received for an asset or paid to transfer a liability (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. There are three levels of inputs that may be used to measure fair values: 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 other 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 company's own assumptions about the assumptions that market participants would use in pricing an asset or liability. The Company used the following methods and significant assumptions to estimate the fair value of each type of financial instrument: Investment Securities: Securities available for sale are recorded at fair value on a recurring basis as follows: the fair values for investment securities are determined by quoted market prices, if available (Level 1). For securities where quoted prices are not available, fair values are calculated based on market prices of similar securities (Level 2). No securities are valued using a Level 3 approach. Loans Held for Sale, at Fair Value: The fair value of loans held for sale is determined using quoted prices for similar assets, adjusted for specific attributes of that loan (Level 2). Mortgage banking related derivatives including interest rate locks with customers and commitments to sell loans are also recorded at fair value using observable market data as of the measurement date (Level 2) but were not significant at period ended March 31, 2018 or December 31, 2017 . Loans Measured at Fair Value: During the normal course of business, loans originated with the initial intention to sell but not ultimately sold, are transferred from held for sale to our portfolio of loans held for investment at fair value as the Company adopted the fair value option at origination. The fair value of these loans is determined by obtaining fair value pricing from a third-party software, and then layering an additional adjustment, ranging from 5 to 75 basis points, as determined by management, depending on the reason for the transfer. Due to the adjustments made, the Company classifies the loans transferred from loans held for sale as recurring Level 3. Impaired Loans: The fair value of impaired loans with specific allocations of the allowance for loan losses is generally based on recent real estate or collateral 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 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. Non-real estate collateral may be valued using an appraisal, net book value per the borrower's financial statements, or aging reports, adjusted or discounted based on management's historical knowledge, changes in market conditions from the time of the valuation, and management's expertise and knowledge of the client and client's business, resulting in a Level 3 fair value classification. Other Real Estate Owned: The fair value of other real estate owned is based on recent real estate appraisals which are generally updated annually. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales, cost, 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. Other real estate owned properties are evaluated on a quarterly basis for additional impairment and adjusted accordingly. Appraisals for both collateral-dependent impaired loans and real estate owned are performed by certified general appraisers (for commercial properties) or certified residential appraisers (for residential properties) whose qualifications and licenses have been reviewed and verified by the Company. Once received, management reviews the assumptions and approaches utilized in the appraisal as well as the overall resulting fair value in comparison with independent data sources such as recent market data or industry-wide statistics. Management monitors the actual selling price of collateral that has been sold to the most recent appraised value to determine what additional adjustment should be made to the appraisal value to arrive at fair value.

The carrying amounts of fed funds sold and interest bearing due from bank accounts approximate fair values and are classified as Level 2. (b) FHLB Stock It is not practical to determine the fair value of FHLB stock due to restrictions placed on its transferability. (c) Loans Fair value of loans, excluding loans held for sale, are estimated as follows: Fair values for all loans are estimated using discounted cash flow analyses, using interest rates currently being offered for loans with similar terms to borrowers of similar credit quality resulting in a Level 3 classification. Impaired loans are values at the lower of cost or fair value as described previously. The methods utilized to estimate the fair value of loans do not necessarily represent an exit price. (d) Deposits The fair values disclosed for demand deposits (e.g., interest and non-interest checking, passbook savings, and money market accounts) are, by definition, equal to the amount payable on demand at the reporting date (i.e., their carrying amount) resulting in a Level 2 classification. Fair values for fixed and variable rate certificates of deposit are estimated using a discounted cash flows calculation that applies interest rates currently being offered on certificates of aggregated expected monthly maturities on time deposits resulting in a Level 2 classification. (e) Borrowings The fair values of the Company's short-term and long-term borrowings are estimated using discounted cash flow analyses based on the current borrowing rates for similar types of borrowing arrangements resulting in a Level 2 classification. (f) Accrued Interest Receivable/Payable The carrying amounts of accrued interest approximate fair value resulting in a Level 3 classification for receivable and a Level 2 classification for payable, consistent with their associated assets/liabilities.

Regulatory Capital Matters

Regulatory Capital Matters	3 Months Ended

Regulated Operations [Abstract]
Regulatory Capital Matters	REGULATORY CAPITAL MATTERS Banks and bank holding companies are subject to regulatory capital requirements administered by federal banking agencies. Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations, involve quantitative measures of assets, liabilities, and certain off-balance sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can initiate regulatory action. Management believed as of March 31, 2018 , the Company and Bank met all capital adequacy requirements to which they were subject. Effective January 1, 2015, the new Basel III regulatory capital framework as approved by federal banking agencies became effective, which is subject to a multi-year phase-in period. The adoption of this new framework modified the calculation of the various capital ratios, added a new ratio, common equity tier 1, and revised the adequately and well capitalized thresholds. In addition, Basel III established a new capital conservation buffer of 2.5% of risk-weighted assets, which is phased-in over a four-year period beginning January 1, 2016. The capital conservation buffer was 1.875% for March 31, 2018 and was 1.25% at December 31, 2017 . Prompt corrective action regulations provide five classifications: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized, although these terms are not used to represent overall financial condition. If adequately capitalized, regulatory approval is required to accept brokered deposits. If undercapitalized, capital distributions are limited, as is asset growth and expansion, and capital restoration plans are required. At March 31, 2018 and December 31, 2017 , the most recent regulatory notifications categorized the Bank as "well capitalized" under the regulatory framework for prompt corrective action. There are no conditions or events since that notification that management believes have changed the institution's category.

Fair Value	FAIR VALUE Fair value is the exchange price that would be received for an asset or paid to transfer a liability (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. There are three levels of inputs that may be used to measure fair values: 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 other 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 company's own assumptions about the assumptions that market participants would use in pricing an asset or liability. The Company used the following methods and significant assumptions to estimate the fair value of each type of financial instrument: Investment Securities: Securities available for sale are recorded at fair value on a recurring basis as follows: the fair values for investment securities are determined by quoted market prices, if available (Level 1). For securities where quoted prices are not available, fair values are calculated based on market prices of similar securities (Level 2). No securities are valued using a Level 3 approach. Loans Held for Sale, at Fair Value: The fair value of loans held for sale is determined using quoted prices for similar assets, adjusted for specific attributes of that loan (Level 2). Mortgage banking related derivatives including interest rate locks with customers and commitments to sell loans are also recorded at fair value using observable market data as of the measurement date (Level 2) but were not significant at period ended March 31, 2018 or December 31, 2017 . Loans Measured at Fair Value: During the normal course of business, loans originated with the initial intention to sell but not ultimately sold, are transferred from held for sale to our portfolio of loans held for investment at fair value as the Company adopted the fair value option at origination. The fair value of these loans is determined by obtaining fair value pricing from a third-party software, and then layering an additional adjustment, ranging from 5 to 75 basis points, as determined by management, depending on the reason for the transfer. Due to the adjustments made, the Company classifies the loans transferred from loans held for sale as recurring Level 3. Impaired Loans: The fair value of impaired loans with specific allocations of the allowance for loan losses is generally based on recent real estate or collateral 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 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. Non-real estate collateral may be valued using an appraisal, net book value per the borrower's financial statements, or aging reports, adjusted or discounted based on management's historical knowledge, changes in market conditions from the time of the valuation, and management's expertise and knowledge of the client and client's business, resulting in a Level 3 fair value classification. Other Real Estate Owned: The fair value of other real estate owned is based on recent real estate appraisals which are generally updated annually. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales, cost, 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. Other real estate owned properties are evaluated on a quarterly basis for additional impairment and adjusted accordingly. Appraisals for both collateral-dependent impaired loans and real estate owned are performed by certified general appraisers (for commercial properties) or certified residential appraisers (for residential properties) whose qualifications and licenses have been reviewed and verified by the Company. Once received, management reviews the assumptions and approaches utilized in the appraisal as well as the overall resulting fair value in comparison with independent data sources such as recent market data or industry-wide statistics. Management monitors the actual selling price of collateral that has been sold to the most recent appraised value to determine what additional adjustment should be made to the appraisal value to arrive at fair value.

The Company recorded $749 thousand in chargeoffs related to our impaired loans at fair value in the three months ended March 31, 2018 . There were no impaired loans at fair value at December 31, 2017 . Other real estate owned measured at fair value had a net carrying amount of $652 thousand at December 31, 2017 . There were no write downs in other real estate owned during the year ended December 31, 2017 . There were no other real estate owned assets at fair value at March 31, 2018 .

The carrying amounts of fed funds sold and interest bearing due from bank accounts approximate fair values and are classified as Level 2. (b) FHLB Stock It is not practical to determine the fair value of FHLB stock due to restrictions placed on its transferability. (c) Loans Fair value of loans, excluding loans held for sale, are estimated as follows: Fair values for all loans are estimated using discounted cash flow analyses, using interest rates currently being offered for loans with similar terms to borrowers of similar credit quality resulting in a Level 3 classification. Impaired loans are values at the lower of cost or fair value as described previously. The methods utilized to estimate the fair value of loans do not necessarily represent an exit price. (d) Deposits The fair values disclosed for demand deposits (e.g., interest and non-interest checking, passbook savings, and money market accounts) are, by definition, equal to the amount payable on demand at the reporting date (i.e., their carrying amount) resulting in a Level 2 classification. Fair values for fixed and variable rate certificates of deposit are estimated using a discounted cash flows calculation that applies interest rates currently being offered on certificates of aggregated expected monthly maturities on time deposits resulting in a Level 2 classification. (e) Borrowings The fair values of the Company's short-term and long-term borrowings are estimated using discounted cash flow analyses based on the current borrowing rates for similar types of borrowing arrangements resulting in a Level 2 classification. (f) Accrued Interest Receivable/Payable The carrying amounts of accrued interest approximate fair value resulting in a Level 3 classification for receivable and a Level 2 classification for payable, consistent with their associated assets/liabilities.

Subsequent Events [Abstract]
Subsequent Events	SUBSEQUENT EVENTS On April 17, 2018, the Company's shareholders approved the 2018 Plan at the annual shareholders meeting. Under the 2018 Plan, the Company can grant incentive and non-qualified stock options, stock awards, stock appreciation rights, and other incentive awards to directors and employees of, and certain service providers to, the Company and its subsidiaries. The Company has reserved 250,000 shares of common stock for issuance under the 2018 Plan. Since the approval of the 2018 Plan, no further awards may be granted under the Stock Option Plan or the 2014 Equity Incentive Plan. However, any outstanding equity award granted under the Stock Option Plan or the 2014 Equity Incentive Plan will remain subject to the terms of such plans until the time it is no longer outstanding. On April 24, 2018, the Company sold 1,150,765 shares of common stock in its initial public offering, including 180,000 shares of common stock pursuant to the exercise in full by the underwriters of their option to purchase additional shares. The aggregate offering price for the shares sold by the Company was $32.2 million , and after deducting $2.1 million of underwriting discounts and $1.1 million of offering expenses paid to third parties, the Company received total net proceeds of $29.0 million from the initial public offering. In addition, certain selling shareholders participated in the offering and sold an aggregate of 229,235 shares of our common stock at an aggregate offering price of $6.4 million . The Company did not receive any proceeds from the sales of shares by the selling shareholders. During the quarter ended March 31, 2018, the Company took a chargeoff of $734 thousand on one of its nonaccrual loans, due to the uncertainty of sale of the customer's business, and therefore deemed the loan collateral dependent and the entire collateral shortfall was charged off at month-end. On April 27, 2018, the sale of the business supporting the nonaccrual loan closed and the Company received a full recovery of the $734 thousand charge off taken in March.

Basis of Presentation and Sum24

Basis of Presentation and Summary of Significant Accounting Policies (Policies)	3 Months Ended
	Mar. 31, 2018
Accounting Policies [Abstract]
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation: The accompanying unaudited consolidated financial statements and notes thereto of the Company have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”) for Form 10-Q and conform to practices within the banking industry and include all of the information and disclosures required by accounting principles generally accepted in the United States of America (“GAAP”) for interim financial reporting. The accompanying unaudited consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments), which are necessary for a fair presentation of financial results for the interim periods presented. The results of operations for the interim periods are not necessarily indicative of the results for the full year. These interim unaudited financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto as of and for the year ended December 31, 2017, included in our registration statement on Form S-1, as amended, filed with the SEC on April 12, 2018 and declared effective on April 19, 2018. The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, the Bank and Hamilton Court, after elimination of significant intercompany transactions and accounts.
Use of Estimates	Use of Estimates: To prepare financial statements in conformity with U.S. generally accepted accounting principles ("GAAP"), management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided, therefore future results could differ. Estimates that are particularly susceptible to significant change include the determination of the allowance for loan losses, expected cash flows from acquired loans, fair value amounts related to business combinations, income taxes, goodwill impairment and those assets and liabilities that require fair value measurement.
Recent Accounting Standards	Recent Accounting Standards: Revenue Recognition In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-09 "Revenue from Contracts with Customers (Topic 606)," which provides a framework for revenue recognition that replaces the existing industry and transaction specific requirements under the existing standards. ASU 2014-09 requires an entity to apply a five-step model to determine when to recognize revenue and at what amount. The model specifies that revenue should be recognized when (or as) an entity transfers control of goods or services to a customer at the amount in which the entity expects to be entitled. Depending on whether certain criteria are met, revenue should be recognized either over time, in a manner that depicts the entity's performance, or at a point in time, when control of the goods or services are transferred to the customer. The amendments of ASU 2014-09 may be applied either retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying ASU 2014-09 recognized at the date of initial application. The guidance will be effective for the Company for the fiscal year ended after December 31, 2018 . The Company plans to adopt these amendments during the first quarter of 2019. The Company is continuing to evaluate the impact ASU 2014-09 will have on our consolidated financial statements. Based on this evaluation to date, management has determined that the majority of the revenues earned by the Company are not within the scope of ASU 2014-09, and that some of the revenue streams that have been identified as being in scope would include service charges and interchange fees. Management will continue to evaluate the impact the adoption of ASU 2014-09 will have on our consolidated financial statements, focusing on noninterest income sources within the scope of ASU 2014-09 as well as new disclosures required by these amendments; however, the adoption of ASU 2014-09 is not expected to have a material impact on the Company's consolidated financial statements but is expected to result in additional disclosures. Financial Instruments In January 2016, the FASB issued ASU No. 2016-01, "Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities," to improve the accounting for financial instruments. This ASU requires equity investments with readily determinable fair values to be measured at fair value with changes recognized in net income regardless of classification. For equity investments without a readily determinable fair value, the value of the investment would be measured at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer instead of fair value, unless a qualitative assessment indicates impairment. Additionally, this ASU requires the separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements, as well as the required use of exit pricing when measuring the fair value of financial instruments for disclosure purposes. This guidance is effective for fiscal years beginning after December 15, 2018, and interim periods within fiscal years beginning after December 15, 2019, and is to be applied prospectively with a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. Management is in the planning stages of developing processes and procedures to comply with the disclosures requirements of this ASU, which could impact the disclosures the Company makes related to fair value of its financial instruments. The Company is planning to adopt this new guidance within the time frames stated above. Leases In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)," to improve transparency and comparability across entities regarding leasing arrangements. This ASU requires the recognition of a separate lease liability representing the required discounted lease payments over the lease term and a separate lease asset representing the right to use the underlying asset during the same lease term. Additionally, this ASU provides clarification regarding the identification of certain components of contracts that would represent a lease as well as requires additional disclosures to the notes of the financial statements. This guidance is effective for fiscal years beginning after December 15, 2019, and interim periods within fiscal years beginning after December 15, 2020, and is to be applied under a modified retrospective approach. The Company is currently evaluating the impact of adopting this new guidance on the consolidated financial statements. Additionally, the Company does not expect to significantly change operating lease agreements prior to adoption. The Company is planning to adopt this new guidance within the time frames stated above. Allowance for Credit Losses In June 2016, the FASB issued ASU No. 2016-13, "Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments," to replace the current incurred loss methodology for recognizing credit losses, which delays recognition until it is probable a loss has been incurred, with a methodology that reflects an estimate of all expected credit losses and considers additional reasonable and supportable forecasted information when determining credit loss estimates. This impacts the calculation of the allowance for credit losses for all financial assets measured under the amortized cost basis, including PCI loans at the time of and subsequent to acquisition. Additionally, credit losses related to available-for-sale debt securities would be recorded through the allowance for credit losses and not as a direct adjustment to the amortized cost of the securities. This guidance is effective for fiscal years beginning after December 15, 2020, including interim periods after those fiscal years, and is to be applied under a modified retrospective approach. The Company is currently evaluating the impact of adopting this new guidance on the consolidated financial statements as well as the impact on current systems and processes. At this time, the Company is reviewing potential methodologies for estimating expected credit losses using reasonable and supportable forecast information as well as has identified certain data and system requirements. Once adopted, we expect our allowance for loan losses to increase through a one-time adjustment to retained earnings; however, until our evaluation is complete, the estimated increase in allowance will be unknown. The Company is planning to adopt this new guidance within the time frames stated above. Investment Securities The Company elected to early adopt ASU No. 2017-08, "Receivables-Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities ("ASU 2017-08")" during the first quarter of 2017. The guidance in ASU 2017-08 shortens the amortization period for certain callable debt securities that are held at a premium to the earliest call date. Debt securities held at a discount will continue to be amortized as a yield adjustment over the life of the instrument. The early adoption of ASU 2017-08 in the first quarter of 2017 did not have a material impact on the Company's Consolidated Financial Statements. Income Taxes - Tax Cuts and Jobs Act In February 2018, the FASB issued ASU No. 2018-02, "Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (Topic 220)," which allows an entity to elect a reclassification from accumulated other comprehensive income (AOCI) to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act ("TCJA"). The amount of that reclassification should include the effect of changes of tax rate on the deferred tax amount, any related valuation allowance and other income tax effects on the items in AOCI. In addition, the ASU requires that an entity state if an election to reclassify the tax effects to retained earnings is made, along with a description of other income tax effects that are reclassified from AOCI. This guidance is effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years, with early adoption permitted. The Company early adopted the ASU and reclassified $168 thousand from retained earnings to AOCI during the first quarter of 2018. In May 2018, the FASB issued an update ASU No. 2018-05, "Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulleting No. 118," regarding the accounting implications of the recently issued TCJA. The update clarifies that in a company's financial statements that include the reporting period in which the TCJA was enacted, a company must first reflect the income tax effects of the TCJA in which the accounting under GAAP is complete. These amounts would not be provisional amounts. The company would also report provisional amounts for those specific income tax effects for which the accounting under GAAP will be incomplete but for which a reasonable estimate can be determined. This accounting update is effective immediately. The Company believes its accounting for the income tax effects of the TCJA is complete. Technical corrections or other forthcoming guidance could change how we interpret provisions of the TCJA, which may impact our effective tax rate and could affect our deferred tax assets, tax positions and/or our tax liabilities.
