Organization Consolidation And Presentation Of Financial Statements [Abstract]
Nature of Operations	Note 1 -- Nature of Operations HCI Group, Inc., together with its subsidiaries (“HCI” or the “Company”), is primarily engaged in the property and casualty insurance business through two Florida domiciled insurance companies, Homeowners Choice Property & Casualty Insurance Company, Inc. (“HCPCI”) and TypTap Insurance Company (“TypTap”). Both HCPCI and TypTap are authorized to underwrite various homeowners’ property and casualty insurance products and allied lines business in the state of Florida and in several other states. The operations of both insurance subsidiaries are supported by HCI Group, Inc. and certain HCI subsidiaries. The Company emphasizes the use of internally developed technologies to collect and analyze claims and other supplemental data to generate savings and efficiency for the operations of the insurance subsidiaries. In the first quarter of 2021, the Company reorganized its operations to focus on specific business segments, resulting in the creation of TypTap Insurance Group, Inc. (“TTIG”) with a separate workforce, board of directors and financial reporting structure. In February 2021, TTIG received a capital investment from a third party representing a minority interest as described in Note 18 -- “Redeemable Noncontrolling Interest.” Companies under TTIG include TypTap, TypTap Management Company, Exzeo USA, Inc., and Cypress Tech Development Company, Inc., the parent company of an India company, Exzeo Software Private Limited. TTIG and its subsidiaries are considered a new reporting segment known as TypTap Group. The Company’s reportable segments now include HCPCI insurance operations, TypTap Group, real estate operations, and corporate and other. Real estate operations are conducted by Greenleaf Capital, LLC, the Company’s real estate subsidiary, which is primarily engaged in the businesses of owning and leasing real estate and operating marina facilities. Assumed Business Effective December 31, 2020, United Property & Casualty Insurance Company, an insurance subsidiary of United Insurance Holdings Corporation (“United”), ceded a portion of its personal lines insurance business in the states of Connecticut, New Jersey, Massachusetts, and Rhode Island to HCPCI. Under the reinsurance agreement, HCPCI provides 69.5% quota share reinsurance on all of United’s in-force, new and renewal policies in those states from December 31, 2020 through May 31, 2021. In exchange, HCPCI paid United an allowance of $4,400 towards already purchased catastrophe reinsurance and a provisional ceding commission of 25% of premium. That percentage could increase up to 31.5% depending on the direct loss ratio results from the reinsured business. On January 18, 2021, the Company entered into a renewal rights agreement with United in connection with the assumed business. Under the agreement, the Company acquired all rights to renew and/or replace United’s homeowners insurance policies at the end of their respective policy periods in the states of Connecticut, Massachusetts, New Jersey and Rhode Island. The policy replacement date is June 1, 2021 or such other date as mutually agreed by both parties. The agreement also contains a non-compete clause that does not permit United to engage in marketing, selling, writing, renewing, or servicing any homeowners insurance contracts in these states until July 1, 2024. In return, United received 100,000 shares of HCI’s common stock and will receive a 6% commission on any replacement premium in excess of $80,000. The total commission will not exceed $3,100. The Company and United agreed to postpone the policy replacement date under the renewal rights agreement to a later date and the Company, through HCPCI and TypTap, entered into a new quota share reinsurance agreement in June 2021 to provide 100% reinsurance on all of United’s in-force, new and renewal policies in those states from June 1, 2021 through May 31, 2022. Under the new agreement, each insurance subsidiary assumes 50% of the business and pays United a ceding commission of 24% of premium.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 2 -- Summary of Significant Accounting Policies Basis of Presentation The accompanying unaudited consolidated financial statements for HCI Group, Inc. and its majority-owned and controlled subsidiaries (collectively, the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information, and the Securities and Exchange Commission (“SEC”) rules for interim financial reporting. Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with U.S. GAAP have been omitted pursuant to such rules and regulations. However, in the opinion of management, the accompanying consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the Company’s financial position as of June 30, 2021 and the results of operations and cash flows for the interim periods presented. The results of operations for the interim periods presented are not necessarily indicative of the results of operations to be expected for any subsequent interim period or for the fiscal year ending December 31, 2021. The accompanying unaudited consolidated financial statements and notes thereto should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2020 included in the Company’s Form 10-K, which was filed with the SEC on March 12, 2021. In preparing the interim unaudited consolidated financial statements, management was required to make certain judgments, assumptions, and estimates that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosures at the financial reporting date and throughout the periods being reported upon. Certain of the estimates result from judgments that can be subjective and complex and consequently actual results may differ from these estimates. Material estimates that are particularly susceptible to significant change in the near term are related to the Company’s losses and loss adjustment expenses, which include amounts estimated for claims incurred but not yet reported. The Company uses various assumptions and actuarial data it believes to be reasonable under the circumstances to make these estimates. In addition, accounting policies specific to reinsurance with retrospective provisions, reinsurance recoverable, deferred income taxes, limited partnership investments, warrants, redeemable noncontrolling interest, intangible assets acquired from United, and stock-based compensation expense involve significant judgments and estimates material to the Company’s consolidated financial statements. All significant intercompany balances and transactions have been eliminated. Adoption of New Accounting Standards Accounting Standards Update No. 2020-06. In August 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2020-06 (“ASU 2020-06”) Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40). ASU 2020-06 removes certain bifurcation models for convertible debt instruments and convertible preferred stock. Therefore, the embedded conversion features no longer are separated from the host contract for convertible instruments with conversion features that are not required to be accounted for as derivatives under Topic 815, Derivatives and Hedging, or that do not result in substantial premiums accounted for as paid-in-capital. The amendments also remove three settlement conditions that are required for equity contracts to qualify for the derivative scope exception and amend the derivative scope exception guidance for contracts in an entity’s own equity. In addition, the amendments expand disclosure requirements for convertible instruments and simplify areas of the guidance for diluted earnings-per-share calculations that are impacted by the amendments. The Company elected to early adopt this update on January 1, 2021 using the modified retrospective method. The adoption of this update increased long-term debt by $3,999 and simultaneously decreased beginning retained income and deferred income tax liabilities by $3,018 and $981, respectively. The if-converted method will be the only permissible method for computing the dilutive effect of a convertible debt instrument. Interest expense no longer includes amortization of debt discount. Redeemable Noncontrolling Interest Redeemable noncontrolling interest represents an economic interest in TTIG and is presented in the temporary equity (mezzanine) section of the consolidated balance sheet. The interest contains rights in dividends, voting, conversion, participation, liquidation preference and redemption. The redemption feature is not solely within the control of TTIG (See Note 18 -- “Redeemable Noncontrolling Interest”). The redeemable noncontrolling interest is initially recorded at fair value and is decreased by related issuance costs. The fair value is estimated using a residual fair value approach. The effect of increasing dividend rates is accreted to the redeemable noncontrolling interest with a corresponding debit to retained income. The effective interest method is used for accretion over the period of the increasing dividend rates. The carrying value of the interest is also subsequently adjusted for accrued dividends and dividend payments. The Company has an option to pay the dividends in cash or make a payment in kind. The dividends are accrued monthly assuming that they will be settled in cash. When the redemption is probable, the Company elects to recognize changes in the redemption value immediately as it occurs and adjust the carrying value of the interest to the maximum redemption value which is the higher of the redemption price or fair market value at the reporting date. Such changes in the redemption value are treated as dividends when calculating income available to common stockholders. Noncontrolling Interests The Company has noncontrolling interests attributable to TTIG. A noncontrolling interest arises when the Company has less than 100% of the voting rights and economic interests in a subsidiary. The noncontrolling interest is periodically adjusted for the expensing of TTIG’s restricted stock awards granted to its employees, the interest’s share of TTIG’s net income or loss to common stockholders and change in other comprehensive income or loss. Stock-Based Compensation The Company accounts for stock-based compensation under the fair value recognition provisions of U.S. GAAP which requires the measurement and recognition of compensation for all stock-based awards made to employees and directors based on estimated fair values. In accordance with U.S. GAAP, the fair value of stock-based awards is generally recognized as compensation expense over the requisite service period, which is defined as the period during which a recipient is required to provide service in exchange for an award. Forfeitures of the Company’s stock-based awards are accounted for as they occur. The Company uses a straight-line attribution method for all grants that include only a service condition. Restricted stock grants with market conditions are expensed over the derived service period. Expensing market-based awards may be expedited if the conditions are met sooner than anticipated. The Company’s outstanding stock-based awards include stock options and restricted stock awards with service and market conditions. Compensation expense related to all awards is included in general and administrative personnel expenses. The Company receives a windfall tax benefit for certain stock option exercises and for restricted stock awards if these awards vest at a higher value than the value used to recognize compensation expense. In the event the restricted stock awards vest at a lower value than the value used to recognize compensation expense, the Company experiences a tax shortfall. The Company recognizes tax windfalls and shortfalls in the consolidated statements of income. Reclassification In response to the new reporting segment described in Note 1 -- “Nature of Operations,” the prior period segment information has been reclassified to conform with the current period presentation. TypTap and TypTap Management Company were removed from the segment previously referred to as Insurance Operations to form the new TypTap Group segment. The information technology companies which had previously been presented in the Corporate and Other segment were also added to the TypTap Group segment.

Accounting Changes And Error Corrections [Abstract]
Recent Accounting Pronouncements	Note 3 -- Recent Accounting Pronouncements Accounting Standards Update No. 2021-01. In January 2021, the FASB issued Accounting Standards Update No. 2021-01 (“ASU 2021-01”) Reference Rate Reform (Topic 848). This update refines the scope of ASC 848 and clarifies some of its guidance as part of the Board’s monitoring of global reference rate reform activities. ASU 2021-01 permits entities to apply certain optional expedients to modifications of interest rate indexes used for margining, discounting or contract price alignment of certain derivatives in connection with reference rate reform activities under way in global financial markets. It also extends optional expedients to account for a derivative contract modified as a continuation of the existing contract and to continue hedge accounting when certain critical terms of a hedging relationship change to modifications made as part of the discounting transition. ASU 2021-01 is effective immediately and does not have any material impact on the Company’s consolidated financial statements. Accounting Standards Update No. 2021-04. In May 2021, the FASB issued Accounting Standards Update No. 2021-04 (“ASU 2021-04”) Earnings Per Share (Topic 260), Debt - Modifications and Extinguishments (Subtopic 470-50), Compensation - Stock Compensation (Topic 718), and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40). This update clarifies and reduces diversity in an issuer’s accounting for modifications or exchanges of freestanding equity-classified written call options (for example, warrants) that remain equity classified after modification or exchange. The guidance clarifies whether an issuer should account for a modification or an exchange of a freestanding equity-classified written call option that remains equity classified after modification or exchange as (1) an adjustment to equity and, if so, the related earnings per share effects, if any, or (2) an expense and, if so, the manner and pattern of recognition. ASU 2021-04 is effective for the Company beginning with the first quarter of 2022 and will be applied prospectively. Early adoption is permitted. This guidance will not have a material impact on the Company’s consolidated financial statements.

Allowance for Credit Losses of Available-for-Sale Fixed-Maturity Securities The Company regularly reviews its individual investment securities for credit impairment. The Company considers various factors in determining whether a credit loss exists for each individual security, including- • the financial condition and near-term prospects of the issuer, including any specific events that may affect its operations or earnings; • the extent to which the market value of the security has been below its cost or amortized cost; • general market conditions and industry or sector specific factors and other qualitative factors; • nonpayment by the issuer of its contractually obligated interest and principal payments; and • the Company’s intent and ability to hold the investment for a period of time sufficient to allow for the recovery of costs. The table below summarizes the activity in the allowance for credit losses of available-for-sale securities for the three and six months ended June 30, 2021 and 2020: 2021 2020 Balance at January 1 $ 588 $ — Credit loss expense — 439 Reductions for securities sold (9 ) — Balance at March 31 $ 579 $ 439 Credit loss expense — 87 Reductions for securities exchanged (579 ) — Balance at June 30 $ — $ 526 b) Equity Securities The Company holds investments in equity securities measured at fair values which are readily determinable.

Fair Value Measurements

Fair Value Measurements	6 Months Ended
	Jun. 30, 2021
Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 7 -- Fair Value Measurements The Company records and discloses certain financial assets at their estimated fair values. The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three broad levels as follows: Level 1 - Unadjusted quoted prices in active markets for identical assets. Level 2 - Other inputs that are observable for the asset, either directly or indirectly such as quoted prices for identical assets that are not observable throughout the full term of the asset. Level 3 - Inputs that are unobservable. Valuation Methodology Cash and Cash Equivalents Cash and cash equivalents primarily consist of money-market funds and certificates of deposit maturing within 90 days. Their carrying value approximates fair value due to the short maturity and high liquidity of these funds. Restricted Cash Restricted cash represents cash held by state authorities and the carrying value approximates fair value. Fixed-Maturity and Equity Securities Estimated fair values of the Company’s fixed-maturity and equity securities are determined in accordance with U.S. GAAP, using valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. Fair values are generally measured using quoted prices in active markets for identical securities or other inputs that are observable either directly or indirectly, such as quoted prices for similar securities. In those instances where observable inputs are not available, fair values are measured using unobservable inputs. Unobservable inputs reflect the Company’s own assumptions about the assumptions that market participants would use in pricing the security and are developed based on the best information available in the circumstances. Fair value estimates derived from unobservable inputs are significantly affected by the assumptions used, including the discount rates and the estimated amounts and timing of future cash flows. The derived fair value estimates cannot be substantiated by comparison to independent markets and are not necessarily indicative of the amounts that would be realized in a current market exchange. The estimated fair values for securities that do not trade on a daily basis are determined by management, utilizing prices obtained from an independent pricing service and information provided by brokers, which are level 2 inputs. Management reviews the assumptions and methods utilized by the pricing service and then compares the relevant data and pricing to broker-provided data. The Company gains assurance of the overall reasonableness and consistent application of the assumptions and methodologies and compliance with accounting standards for fair value determination through ongoing monitoring of the reported fair values. Revolving Credit Facility The Company’s revolving credit facility is a variable-rate loan. The interest rate is periodically adjusted based on the London Interbank Offered Rate plus a spread. As a result, its carrying value approximates fair value. Long-Term Debt The following table summarizes components of the Company’s long-term debt and methods used in estimating their fair values: Maturity Date Valuation Methodology 4.25% Convertible senior notes 2037 Quoted price 3.90% Promissory note 2032 Discounted cash flow method/Level 3 inputs 3.75% Callable promissory note 2036 Discounted cash flow method/Level 3 inputs 4.55% Promissory note 2036 Discounted cash flow method/Level 3 inputs Assets Measured at Estimated Fair Value on a Recurring Basis The following table presents information about the Company’s financial assets measured at estimated fair value on a recurring basis.

(b) The entire amount was fully amortized in June 2021 due to its immateriality. (c) Will be amortized over four years after the policy replacement date. The Company recorded intangible assets of $7,829 representing the renewal rights and non-compete agreement described in Note 1 -- “Nature of Operations” in exchange for 100,000 shares of HCI’s common stock and contingent consideration which is a 6% commission on any replacement premium in excess of $80,000. The contingent consideration was estimated at $2,419 which was included in other liabilities on the consolidated balance sheet. Due to the postponement of the renewal and/or replacement of United’s policies as described in Note 1 -- "Nature of Operations,” amortization of the policy renewal rights intangible asset has yet to begin. The renewal rights and non-compete intangible assets acquired do not meet the definition of a business as substantially all of the fair value of the intangible assets acquired are concentrated in a group of similar assets. Therefore, the Company accounted for the purchase of the renewal rights and non-compete intangible assets as an asset acquisition. Total consideration paid consisted of $5,410 worth of HCI’s common stock plus a contingent liability of $2,419.

Accordingly, as of June 30, 2021, the conversion rate of the Company’s 4.25% Convertible Notes was 16.4594 shares of common stock for each $1 in principal amount, which was the equivalent of approximately $60.76 per share. During the second quarter of 2021, the Company’s common shares traded above 130% of the conversion price for at least 20 trading days during the final 30 trading days of the quarter. As a result, the 4.25% Convertible Notes are convertible by all holders beginning July 1 through September 30, 2021 in accordance with the terms specified in the indenture. As of June 30, 2021, the remaining amortization period of the debt issuance costs for the 4.25% Convertible Notes was expected to be 8 months.

Insurance [Abstract]
Reinsurance	Note 12 -- Reinsurance The Company cedes a portion of its homeowners’ insurance exposure to other entities under catastrophe excess of loss reinsurance contracts and one quota share reinsurance agreement. Ceded premiums under most catastrophe excess of loss reinsurance contracts are subject to revision resulting from subsequent adjustments in total insured value. Under the terms of the quota share reinsurance agreement, the Company is entitled to a 30% ceding commission on ceded premiums written. The reinsurance premiums under one flood catastrophe excess of loss reinsurance contract are generally determined on a quarterly basis based on the premiums associated with the applicable flood total insured value in force on the last day of the preceding quarter. The Company remains liable for claims payments in the event that any reinsurer is unable to meet its obligations under the reinsurance agreements. Failure of reinsurers to honor their obligations could result in losses to the Company. The Company evaluates the financial condition of its reinsurers and monitors concentrations of credit risk arising from similar geographic regions, activities or economic characteristics of the reinsurers to minimize its exposure to significant losses from reinsurer insolvencies. The Company contracts with a number of reinsurers to secure its annual reinsurance coverage, which generally becomes effective June 1 st of each year. The Company purchases reinsurance each year taking into consideration probable maximum losses and reinsurance market conditions. The impact of the reinsurance contracts on premiums written and earned is as follows: Three Months Ended Six Months Ended June 30, June 30, 2021 2020 2021 2020 Premiums Written: Direct $ 143,224 $ 171,906 $ 253,355 $ 248,478 Assumed 41,754 (25 ) 57,471 (79 ) Gross written 184,978 171,881 310,826 248,399 Ceded (46,436 ) (34,354 ) (89,535 ) (65,073 ) Net premiums written $ 138,542 $ 137,527 $ 221,291 $ 183,326 Premiums Earned: Direct $ 115,733 $ 106,852 $ 226,025 $ 197,619 Assumed 23,707 951 44,357 2,549 Gross earned 139,440 107,803 270,382 200,168 Ceded (46,436 ) (34,354 ) (89,535 ) (65,073 ) Net premiums earned $ 93,004 $ 73,449 $ 180,847 $ 135,095 During the three and six months ended June 30, 2021, the Company recognized ceded losses of $487 and $594, respectively, as a reduction in losses and loss adjustment expenses. During the three and six months ended June 30, 2020, the Company recognized ceded losses of $11 and $349, respectively, as a reduction in losses and loss adjustment expenses. At June 30, 2021 and December 31, 2020, there were 54 and 38 reinsurers, respectively, participating in the Company’s reinsurance program. Total net amounts recoverable and receivable from reinsurers at June 30, 2021 and December 31, 2020 were $61,993 and $85,146, respectively. Approximately 66.8% of the gross reinsurance recoverable balance at June 30, 2021 was receivable from three reinsurers, including the Florida Hurricane Catastrophe Fund, a state trust fund. Based on all available information considered in the rating-based method, the Company recognized decreases in credit loss expense of $16 and $28 for the three and six months ended June 30, 2021, respectively. For the three and six months ended June 30, 2020, the Company derecognized credit loss expenses of $325 and $349, respectively. Allowances for credit losses related to the reinsurance recoverable balance were $57 and $85 at June 30, 2021 and December 31, 2020, respectively. The Company has reinsurance contracts that include retrospective provisions that adjust premiums in the event losses are minimal or zero. For the three and six months ended June 30, 2021, the Company recognized reductions in premiums ceded of $3,575 and $8,255, respectively, related to these adjustments in the consolidated statements of income. For the three and six months ended June 30, 2020, the Company recognized reductions in premiums ceded of $3,240 and $5,760, respectively. Amounts receivable pursuant to retrospective provisions are reflected in other assets. At June 30, 2021 and December 31, 2020, other assets included $455 and $10,920, respectively. In June 2021, the Company received $18,720 of premium refund under the retrospective reinsurance contract that ended May 31, 2021. Management believes the credit risk associated with the collectability of accrued benefits is minimal as the amount receivable is concentrated with one reinsurer and the Company monitors the creditworthiness of this reinsurer based on available information about the reinsurer’s financial condition. Effective January 2021, the Company began providing quota share reinsurance on all in-force, new and renewal policies issued by United. The policies were issued in the states of Connecticut, New Jersey, Massachusetts and Rhode Island. For the three and six months ended June 30, 2021, assumed premiums written related to United were $41,754 and $57,471, respectively. At June 30, 2021, the Company had a net balance of $24,712 due from United, consisting of premiums receivable of $41,754 offset by ceding commission payable of $9,764 and payable on paid losses and loss adjustment expenses of $7,278.

Insurance [Abstract]
Losses and Loss Adjustment Expenses	Note 13 -- Losses and Loss Adjustment Expenses The liability for losses and loss adjustment expenses (“LAE”) is determined on an individual case basis for all claims reported. The liability also includes amounts for unallocated expenses, anticipated future claim development and losses incurred but not reported. The Company primarily writes insurance in the states which could be exposed to hurricanes or other natural catastrophes. The occurrence of a major catastrophe could have a significant effect on the Company’s quarterly results and cause a temporary disruption of the normal operations of the Company. However, the Company is unable to predict the frequency or severity of any such events that may occur in the near term or thereafter. Activity in the liability for losses and LAE is summarized as follows: Three Months Ended Six Months Ended June 30, June 30, 2021 2020 2021 2020 Net balance, beginning of period* $ 144,630 $ 105,876 $ 141,065 $ 98,174 Incurred, net of reinsurance, related to: Current period 51,310 40,493 93,230 66,296 Prior period 4,607 (650 ) 8,438 1,625 Total incurred, net of reinsurance 55,917 39,843 101,668 67,921 Paid, net of reinsurance, related to: Current period (20,006 ) (11,329 ) (27,602 ) (15,813 ) Prior period (25,640 ) (11,261 ) (60,230 ) (27,153 ) Total paid, net of reinsurance (45,646 ) (22,590 ) (87,832 ) (42,966 ) Net balance, end of period 154,901 123,129 154,901 123,129 Add: reinsurance recoverable before allowance for credit losses 48,884 88,033 48,884 88,033 Gross balance, end of period $ 203,785 $ 211,162 $ 203,785 $ 211,162 * The establishment of loss and LAE reserves is an inherently uncertain process and changes in loss and LAE reserve estimates are expected as these estimates are subject to the outcome of future events. Changes in estimates, or differences between estimates and amounts ultimately paid, are reflected in the operating results of the period during which such estimates are adjusted. During the three and six months ended June 30, 2021, the Company recognized losses related to prior periods of $4,607 and $8,438, respectively, primarily to increase the reserve for the 2020 loss year resulting from increased litigation. Losses and LAE for the six months ended June 30, 2021 included estimated losses, net of reinsurance, of approximately $23,500 related to policies assumed from United, approximately $2,600 of which pertained to TypTap.

Segment Reporting [Abstract]
Segment Information	Note 14 -- Segment Information The Company identifies its operating divisions or segments based on managerial emphasis, organizational structure and revenue source. In the first quarter of 2021, the Company reorganized its operations to focus on specific business segments, resulting in the creation of TTIG with a separate workforce, board of directors and financial reporting structure. Companies under TTIG include TypTap, TypTap Management Company, Exzeo USA, Inc., and Cypress Tech Development Company, Inc., the parent company of an India company, Exzeo Software Private Limited. TTIG and its subsidiaries are considered a new reporting segment known as TypTap Group. The Company now has four reportable segments: HCPCI insurance operations, TypTap Group, real estate operations, and corporate and other. Due to their economic characteristics, the Company’s property and casualty insurance division and reinsurance operations, excluding the insurance operations under TypTap Group, are grouped together into one reportable segment under HCPCI insurance operations. The TypTap Group segment includes its property and casualty insurance operations, information technology operations and its management company’s activities. The real estate operations segment includes companies engaged in operating commercial properties the Company owns for investment purposes or for use in its own operations. The corporate and other segment represents the activities of the holding companies and any other companies that do not meet the quantitative and qualitative thresholds for a reportable segment. The determination of segments may change over time due to changes in operational emphasis, revenues, and results of operations. The Company’s chief executive officer, who serves as the Company’s chief operating decision maker, evaluates each division’s financial and operating performance based on revenue and operating income. For the three months ended June 30, 2021 and 2020, revenues from the HCPCI insurance operations segment before intracompany elimination represented 77.6% and 86.6%, respectively, and revenues from the TypTap Group segment represented 20.3% and 11.1%, respectively, of total revenues of all operating segments. For the six months ended June 30, 2021 and 2020, revenues from the HCPCI insurance operations segment before intracompany elimination represented 77.8% and 83.8%, respectively, and revenues from the TypTap Group segment represented 18.9% and 12.8%, respectively, of total revenues of all operating segments. At June 30, 2021 and December 31, 2020, HCPCI insurance operations’ total assets represented 61.4% and 68.9%, respectively, and TypTap Group’s total assets represented 25.4% and 16.7%, respectively, of the combined assets of all operating segments.

Income Tax Disclosure [Abstract]
Income Taxes	Note 16 -- Income Taxes During the three months ended June 30, 2021 and 2020, the Company recorded approximately $1,267 and $2,887 respectively, of income taxes, which resulted in effective tax rates of 24.9% and 24.4%, respectively. During the six months ended June 30, 2021 and 2020, the Company recorded approximately $4,524 and $2,997, respectively, of income taxes, which resulted in effective tax rates of 29.8% and 24.0%, respectively. The increase in the effective tax rate in 2021 as compared with the corresponding period in the prior year was primarily attributable to an increase in non-deductible compensation expense related to restricted stock granted to certain executives. The Company’s estimated annual effective tax rate differs from the statutory federal tax rate due to state and foreign income taxes as well as certain nondeductible and tax-exempt items.

Earnings Per Share [Abstract]
Earnings Per Share	Note 17 -- Earnings Per Share U.S. GAAP requires the Company to use the two-class method in computing basic earnings per share since holders of the Company’s restricted stock have the right to share in dividends, if declared, equally with common stockholders. These participating securities affect the computation of both basic and diluted earnings per share during periods of net income or loss. For a majority-owned subsidiary, its basic and diluted earnings per share are first computed separately. Then, the Company’s proportionate share in that majority-owned subsidiary’s earnings is added to the computation of both basic and diluted earnings per share at a consolidated level. A summary of the numerator and denominator of the basic and diluted earnings per common share is presented below.

Noncontrolling Interest [Abstract]
Redeemable Noncontrolling Interest	Note 18 -- Redeemable Noncontrolling Interest On February 26, 2021, TTIG completed a capital investment transaction with a fund associated with Centerbridge Partners, L.P. (collectively, the “Lead Investor”), a private investment management fund. Under the investment agreement, TTIG issued 9,000,000 voting shares of its Series A-1 Preferred Stock and 1,000,000 non-voting shares of its Series A-2 Preferred Stock (together “Series A Preferred Stock”), $0.001 par value, at a price of $10 per share for total proceeds of $100,000. The proceeds will be used for TypTap’s operations and continued expansion. The Company incurred $6,262 of related issuance costs. In connection with the transaction, the Lead Investor was granted by HCI warrants to purchase 750,000 shares of HCI’s common stock with an exercise price of $54.40 per share. The warrants valued at $9,217 or $12.29 per warrant were immediately exercisable and will expire on the fourth anniversary of the date of issuance. Dividends Dividends accrue and accumulate from the date of issuance. Cumulative dividends are payable semi-annually in cash or paid-in-kind at TTIG’s option. Cash dividend rates are $0.50 per share in Year 1, $0.60 per share in Year 2, $0.75 per share in Year 3, and $0.95 per share in Year 4 and thereafter. The rates for paid-in-kind dividends are $0.60 per share in Year 1 and $0.70 per share in Year 2. In addition, the Series A Preferred Stock will be paid dividends on an as-converted basis when and if TTIG declares common stock dividends. Conversion Rights The holders of TTIG’s Series A Preferred Stock have the right to convert the stock at any time into shares of TTIG’s common stock with an initial conversion rate of 1 to 1 Redemption Rights On or after the fourth anniversary of the issuance date, TTIG’s Series A Preferred Stock is redeemable at the option of the holders at a price equal to the greater of (1) $10 per share plus any accrued but unpaid dividends and (2) a fair market value per share determined by an independent valuation firm selected by TTIG’s board of directors. Management determined that the redemption was not probable at June 30, 2021. Guaranty by HCI All payment obligations to the holders of TTIG’s Series A Preferred Stock are fully guaranteed by HCI as long as TTIG’s Series A Preferred Stock is outstanding. As the guarantor, HCI is subject to certain financial covenants. Liquidation Preference In the event of any liquidation, the Series A Preferred Stock ranks senior to TTIG’s common stock with respect to distribution rights. Anti-Dilutive Protection The holders of TTIG’s Series A Preferred Stock receive protection in the form of a down-round feature which will be triggered in the event that TTIG issues additional common equivalent shares at an effective price per share less than $10 per share. The following table summarizes the activity of redeemable noncontrolling interest during the six months ended June 30, 2021: Balance at January 1, 2021 $ — Initial proceeds from Centerbridge 100,000 Increase (decrease): Proceeds allocated to warrants* (9,217 ) Issuance costs (6,262 ) Issuance costs allocated to warrants* 577 Accrued cash dividends 458 Accretion - increasing dividend rates 336 Balance at March 31, 2021 $ 85,892 Increase (decrease): Accrued cash dividends 1,250 Accretion - increasing dividend rates 929 Balance at June 30, 2021 $ 88,071 *Net decrease related to warrants of $8,640.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated financial statements for HCI Group, Inc. and its majority-owned and controlled subsidiaries (collectively, the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information, and the Securities and Exchange Commission (“SEC”) rules for interim financial reporting. Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with U.S. GAAP have been omitted pursuant to such rules and regulations. However, in the opinion of management, the accompanying consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the Company’s financial position as of June 30, 2021 and the results of operations and cash flows for the interim periods presented. The results of operations for the interim periods presented are not necessarily indicative of the results of operations to be expected for any subsequent interim period or for the fiscal year ending December 31, 2021. The accompanying unaudited consolidated financial statements and notes thereto should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2020 included in the Company’s Form 10-K, which was filed with the SEC on March 12, 2021. In preparing the interim unaudited consolidated financial statements, management was required to make certain judgments, assumptions, and estimates that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosures at the financial reporting date and throughout the periods being reported upon. Certain of the estimates result from judgments that can be subjective and complex and consequently actual results may differ from these estimates. Material estimates that are particularly susceptible to significant change in the near term are related to the Company’s losses and loss adjustment expenses, which include amounts estimated for claims incurred but not yet reported. The Company uses various assumptions and actuarial data it believes to be reasonable under the circumstances to make these estimates. In addition, accounting policies specific to reinsurance with retrospective provisions, reinsurance recoverable, deferred income taxes, limited partnership investments, warrants, redeemable noncontrolling interest, intangible assets acquired from United, and stock-based compensation expense involve significant judgments and estimates material to the Company’s consolidated financial statements. All significant intercompany balances and transactions have been eliminated.
Adoption of New Accounting Standards	Adoption of New Accounting Standards Accounting Standards Update No. 2020-06. In August 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2020-06 (“ASU 2020-06”) Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40). ASU 2020-06 removes certain bifurcation models for convertible debt instruments and convertible preferred stock. Therefore, the embedded conversion features no longer are separated from the host contract for convertible instruments with conversion features that are not required to be accounted for as derivatives under Topic 815, Derivatives and Hedging, or that do not result in substantial premiums accounted for as paid-in-capital. The amendments also remove three settlement conditions that are required for equity contracts to qualify for the derivative scope exception and amend the derivative scope exception guidance for contracts in an entity’s own equity. In addition, the amendments expand disclosure requirements for convertible instruments and simplify areas of the guidance for diluted earnings-per-share calculations that are impacted by the amendments. The Company elected to early adopt this update on January 1, 2021 using the modified retrospective method. The adoption of this update increased long-term debt by $3,999 and simultaneously decreased beginning retained income and deferred income tax liabilities by $3,018 and $981, respectively. The if-converted method will be the only permissible method for computing the dilutive effect of a convertible debt instrument. Interest expense no longer includes amortization of debt discount.
Redeemable Noncontrolling Interest	Redeemable Noncontrolling Interest Redeemable noncontrolling interest represents an economic interest in TTIG and is presented in the temporary equity (mezzanine) section of the consolidated balance sheet. The interest contains rights in dividends, voting, conversion, participation, liquidation preference and redemption. The redemption feature is not solely within the control of TTIG (See Note 18 -- “Redeemable Noncontrolling Interest”). The redeemable noncontrolling interest is initially recorded at fair value and is decreased by related issuance costs. The fair value is estimated using a residual fair value approach. The effect of increasing dividend rates is accreted to the redeemable noncontrolling interest with a corresponding debit to retained income. The effective interest method is used for accretion over the period of the increasing dividend rates. The carrying value of the interest is also subsequently adjusted for accrued dividends and dividend payments. The Company has an option to pay the dividends in cash or make a payment in kind. The dividends are accrued monthly assuming that they will be settled in cash. When the redemption is probable, the Company elects to recognize changes in the redemption value immediately as it occurs and adjust the carrying value of the interest to the maximum redemption value which is the higher of the redemption price or fair market value at the reporting date. Such changes in the redemption value are treated as dividends when calculating income available to common stockholders.
Noncontrolling Interests	Noncontrolling Interests The Company has noncontrolling interests attributable to TTIG. A noncontrolling interest arises when the Company has less than 100% of the voting rights and economic interests in a subsidiary. The noncontrolling interest is periodically adjusted for the expensing of TTIG’s restricted stock awards granted to its employees, the interest’s share of TTIG’s net income or loss to common stockholders and change in other comprehensive income or loss.
Stock-Based Compensation	Stock-Based Compensation The Company accounts for stock-based compensation under the fair value recognition provisions of U.S. GAAP which requires the measurement and recognition of compensation for all stock-based awards made to employees and directors based on estimated fair values. In accordance with U.S. GAAP, the fair value of stock-based awards is generally recognized as compensation expense over the requisite service period, which is defined as the period during which a recipient is required to provide service in exchange for an award. Forfeitures of the Company’s stock-based awards are accounted for as they occur. The Company uses a straight-line attribution method for all grants that include only a service condition. Restricted stock grants with market conditions are expensed over the derived service period. Expensing market-based awards may be expedited if the conditions are met sooner than anticipated. The Company’s outstanding stock-based awards include stock options and restricted stock awards with service and market conditions. Compensation expense related to all awards is included in general and administrative personnel expenses. The Company receives a windfall tax benefit for certain stock option exercises and for restricted stock awards if these awards vest at a higher value than the value used to recognize compensation expense. In the event the restricted stock awards vest at a lower value than the value used to recognize compensation expense, the Company experiences a tax shortfall. The Company recognizes tax windfalls and shortfalls in the consolidated statements of income.
Reclassification	Reclassification In response to the new reporting segment described in Note 1 -- “Nature of Operations,” the prior period segment information has been reclassified to conform with the current period presentation. TypTap and TypTap Management Company were removed from the segment previously referred to as Insurance Operations to form the new TypTap Group segment. The information technology companies which had previously been presented in the Corporate and Other segment were also added to the TypTap Group segment.
