Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 1 — Summary of Significant Accounting Policies Basis of Presentation The accompanying unaudited, consolidated financial statements for HCI Group, Inc. and its 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, 2016 and the results of operations and cash flows for the 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, 2016. 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, 2015 included in the Company’s Form 10-K, which was filed with the SEC on March 4, 2016. 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 for reinsurance contracts with retrospective provisions, deferred income taxes, 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. Reclassifications.

Expected maturities will differ from contractual maturities as borrowers may have the right to call or prepay obligations with or without penalties. The scheduled contractual maturities of fixed-maturity securities as of June 30, 2016 and December 31, 2015 are as follows: Amortized Estimated As of June 30, 2016 Available-for-sale Due in one year or less $ 4,119 $ 4,093 Due after one year through five years 37,183 37,714 Due after five years through ten years 68,543 68,782 Due after ten years 23,477 25,118 $ 133,322 $ 135,707 Amortized Estimated As of December 31, 2015 Available-for-sale Due in one year or less $ 3,282 $ 3,292 Due after one year through five years 32,833 32,651 Due after five years through ten years 71,120 67,113 Due after ten years 21,379 21,953 $ 128,614 $ 125,009 Sales of Available-for-Sale Securities Proceeds received, and the gross realized gains and losses from sales of available-for-sale securities, for the three and six months ended June 30, 2016 and 2015 were as follows: Proceeds Gross Gross Three months ended June 30, 2016 Fixed-maturity securities $ 32,424 $ 376 $ — Equity securities $ 4,801 $ 220 $ (205 ) Three months ended June 30, 2015 Fixed-maturity securities $ 1,051 $ 1 $ (24 ) Equity securities $ 3,239 $ 121 $ (172 ) Six months ended June 30, 2016 Fixed-maturity securities $ 33,524 $ 383 $ — Equity securities $ 9,155 $ 359 $ (426 ) Six months ended June 30, 2015 Fixed-maturity securities $ 3,285 $ 59 $ (30 ) Equity securities $ 7,994 $ 329 $ (625 ) Other-than-temporary Impairment The Company regularly reviews its individual investment securities for other-than-temporary impairment. The Company considers various factors in determining whether each individual security is other-than-temporarily impaired, including- • the financial condition and near-term prospects of the issuer, including any specific events that may affect its operations or earnings; • the length of time and the extent to which the market value of the security has been below its cost or amortized cost; • general market conditions, 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. At December 31, 2015, the Company had two fixed-maturity securities that were other-than-temporarily impaired. In June 2016, the Company sold one other-than-temporarily impaired fixed-maturity security due to uncertainties surrounding the issuer’s recently announced restructuring plan. Prior to the sale, this security’s remaining $202 of impairment loss was reclassified from comprehensive income and recognized in total other-than-temporary impairment losses in the Company’s consolidated statement of income for the three months ended June 30, 2016. For the six months ended June 30, 2016, the Company recognized $495 of additional impairment loss in the consolidated statement of income, representing $26 of additional loss recorded during the period and the reclassification of $469 previously recorded in other comprehensive income. For the three and six months ended June 30, 2015, there was no other-than-temporary loss related to fixed-maturity securities. The following table presents a rollforward of the cumulative credit losses in other-than-temporary impairment losses recognized in income from available for sale fixed-maturity securities: 2016 2015 Balance at January 1 $ 111 $ — Additional credit impairments on previously impaired securities 293 — Balance at March 31 404 — Credit impaired security fully disposed of for which there was no prior intent or requirement to sell (385 ) — Reduction due to increase in expected cash flows recognized over the remaining life of the previously impaired security (19 ) Balance at June 30 $ — $ — In determining whether equity securities are other than temporarily impaired, the Company considers its intent and ability to hold a security for a period of time sufficient to allow for the recovery of cost, the length of time each security has been in an unrealized loss position, the extent of the decline and the near term prospect for recovery. At June 30, 2016 and December 31, 2015, the Company had 15 and 17 equity securities, respectively, that were other-than-temporarily impaired. The Company recognized impairment losses of $340 and $293, respectively, for the three months ended June 30, 2016 and 2015. For the six months ended June 30, 2016 and 2015, the Company recognized impairment losses of $722 and $1,983, respectively.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 4 — Fair Value Measurements The Company records and discloses certain financial assets at their estimated fair value. 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 and the liability, either directly or indirectly such as quoted prices for identical assets and liabilities that are not observable throughout the full term; and Level 3 - Inputs that are unobservable. Valuation Methodology Cash and cash equivalents Cash and cash equivalents primarily consist of money-market funds. Their carrying value approximates fair value due to the short maturity and high liquidity of these funds. Available-for-sale securities Estimated fair values of the Company’s available-for-sale 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. 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. ADC Arrangement Classified as Real Estate Investment As described in Note 3 — “Investments” under ADC Arrangement Limited Partnership Investments As described in Note 3 — “Investments” under Limited Partnership Investments Long-term debt Long-term debt includes the Company’s 8% senior notes due 2020, 3.875% convertible senior notes due 2019 and 4% promissory note due through 2031. The 8% senior notes trade on the New York Stock Exchange. The estimated fair value of the 8% senior notes is based on the closing market price at each balance sheet date. The 3.875% convertible senior notes were sold in a private offering. The fair values of the 3.875% convertible senior notes and the 4% promissory note are estimated using a discounted cash flow method that relies on 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. The table indicates the fair value hierarchy of the valuation techniques utilized by the Company to determine such fair value as of June 30, 2016 and December 31, 2015: Fair Value Measurements Using (Level 1) (Level 2) (Level 3) Total As of June 30, 2016 Financial Assets: Cash and cash equivalents $ 309,274 $ — $ — $ 309,274 Fixed-maturity securities: U.S. Treasury and U.S. government agencies 1,008 — — 1,008 Corporate bonds 41,781 984 — 42,765 State, municipalities, and political subdivisions — 80,132 — 80,132 Exchange-traded debt 11,418 — — 11,418 Redeemable preferred stock 384 — — 384 Total fixed-maturity securities 54,591 81,116 — 135,707 Equity securities 49,712 — — 49,712 Total available-for-sale securities 104,303 81,116 — 185,419 Total $ 413,577 $ 81,116 $ — $ 494,693 As of December 31, 2015 Financial Assets: Cash and cash equivalents $ 267,738 $ — $ — $ 267,738 Fixed-maturity securities: U.S. Treasury and U.S. government agencies 113 — — 113 Corporate bonds 36,836 983 — 37,819 State, municipalities, and political subdivisions — 77,324 — 77,324 Exchange-traded debt 9,429 — — 9,429 Redeemable preferred stock 324 — — 324 Total fixed-maturity securities 46,702 78,307 — 125,009 Equity securities 48,237 — — 48,237 Total available-for-sale securities 94,939 78,307 — 173,246 Total $ 362,677 $ 78,307 $ — $ 440,984 Assets and Liabilities Carried at Other Than Fair Value The following tables present fair value information for assets and liabilities that are carried on the balance sheet at amounts other than fair value as of June 30, 2016 and December 31, 2015.

Reinsurance

Insurance [Abstract]
Reinsurance	Note 7 — Reinsurance The Company cedes a portion of its homeowners’ insurance exposure to other entities under catastrophe excess of loss reinsurance treaties and one quota share agreement. 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 enters into reinsurance treaties with highly rated and reputable reinsurers and it 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 1st each year. The Company purchases reinsurance each year taking into consideration probable maximum losses and reinsurance market conditions. The impact of the reinsurance treaties on premiums written and earned is as follows: Three Months Ended June 30, Six Months Ended June 30, 2016 2015 2016 2015 Premiums Written: Direct $ 139,761 $ 156,151 $ 215,400 $ 238,140 Assumed (280 ) (841 ) (359 ) (1,376 ) Gross written 139,481 155,310 215,041 236,764 Ceded (36,384 ) (31,378 ) (76,756 ) (59,217 ) Net premiums written $ 103,097 $ 123,932 $ 138,285 $ 177,547 Premiums Earned: Direct $ 94,046 $ 87,196 $ 190,899 $ 170,802 Assumed 866 20,569 2,832 46,530 Gross earned 94,912 107,765 193,731 217,332 Ceded (36,384 ) (31,378 ) (76,756 ) (59,217 ) Net premiums earned $ 58,528 $ 76,387 $ 116,975 $ 158,115 During the three and six months ended June 30, 2016 and 2015, there were no recoveries pertaining to reinsurance contracts that were deducted from losses incurred. At June 30, 2016 and December 31, 2015, there were 35 and 21 reinsurers, respectively, participating in the Company’s reinsurance program. There were no amounts receivable with respect to reinsurers at June 30, 2016 and December 31, 2015. Thus, there were no concentrations of credit risk associated with reinsurance receivables as of June 30, 2016 and December 31, 2015. In addition, based on the insurance ratings and the financial strength of the reinsurers, management believes there was no credit risk associated with its reinsurers’ obligations to perform on any prepaid reinsurance contract as of June 30, 2016 and December 31, 2015. Certain of the reinsurance contracts include retrospective provisions that adjust premiums or increase the amount of future coverage in the event losses are minimal or zero. Effective June 1, 2016, retrospective provisions include premium adjustments only. These adjustments are reflected in the consolidated statements of income as net reductions in ceded premiums of $3,001 and $6,241 for the three months ended June 30, 2016 and 2015, respectively, of which $413 and $1,520 relates to the Company’s contract with Oxbridge Reinsurance Limited (see Note 14 — Related Party Transactions). For the six months ended June 30, 2016 and 2015, these adjustments were $5,822 and $12,614, respectively, of which $740 and $2,125 relates to the Company’s contract with Oxbridge. In June 2016, the Company received a total of $37,800 in cash benefits related to two retrospective reinsurance contracts that terminated May 31, 2016 of which $7,560 was received from Oxbridge. At June 30, 2016 and December 31, 2015, other assets included $6,546 and $36,176, respectively, and prepaid reinsurance premiums included $277 and $2,625, respectively, which are related to these adjustments. Management believes the credit risk associated with the collectability of these 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 position.

Activity in the liability for unpaid losses and loss adjustment expenses is summarized as follows: Three Months Ended June 30, Six Months Ended June 30, 2016 2015 2016 2015 Balance, beginning of period $ 53,271 $ 51,177 $ 51,690 $ 48,908 Incurred related to: Current period 20,803 20,222 47,420 39,054 Prior period 5,469 343 5,932 550 Total incurred 26,272 20,565 53,352 39,604 Paid related to: Current period (14,239 ) (10,256 ) (22,596 ) (15,052 ) Prior period (10,577 ) (7,157 ) (27,719 ) (19,131 ) Total paid (24,816 ) (17,413 ) (50,315 ) (34,183 ) Balance, end of period $ 54,727 $ 54,329 $ 54,727 $ 54,329 The establishment of loss reserves is an inherently uncertain process and changes in loss 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, 2016, the Company experienced unfavorable development of $5,469 and $5,932, respectively, attributable to the settlement and further development of older claims and an increase in late reported claims, primarily claims related to the 2015 loss year. The Company writes insurance in the state of Florida, 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

Income Taxes	Note 9 — Income Taxes During the three months ended June 30, 2016 and 2015, the Company recorded approximately $4,205 and $13,561, respectively, of income taxes, which resulted in effective tax rates of 37.4% and 38.1%, respectively. During the six months ended June 30, 2016 and 2015, the Company recorded approximately $7,846 and $29,229, respectively, of income taxes, which resulted in estimated annual effective tax rates of 37.5% and 38.1%, respectively. The decrease in the 2016 effective tax rate was primarily attributable to an increase in interest income earned from tax-exempt securities relative to overall book income. 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.

Restricted Stock Awards From time to time, the Company has granted and may grant restricted stock awards to its executive officers, other employees and nonemployee directors in connection with their service to the Company. The terms of the Company’s outstanding restricted stock grants may include service, performance and market-based conditions. The fair value of the awards with market-based conditions is determined using a Monte Carlo simulation method, which calculates many potential outcomes for an award and then establishes fair value based on the most likely outcome. The determination of fair value with respect to the awards concerning only performance or service-based conditions is based on the market value of the Company’s common stock on the grant date. Information with respect to the activity of unvested restricted stock awards during the three and six months ended June 30, 2016 and 2015 is as follows: Number of Weighted Fair Value Nonvested at January 1, 2016 620,513 $ 30.33 Vested (20,917 ) $ 48.42 Cancelled (160,000 ) $ 26.27 Forfeited (750 ) $ 45.25 Nonvested at March 31, 2016 438,846 $ 30.93 Granted 102,440 $ 32.21 Vested (24,235 ) $ 37.34 Forfeited (5,147 ) $ 42.20 Nonvested at June 30, 2016 511,904 $ 30.77 Nonvested at January 1, 2015 639,705 $ 28.33 Vested (41,695 ) $ 36.15 Forfeited (1,088 ) $ 48.42 Nonvested at March 31, 2015 596,922 $ 27.75 Granted 83,260 $ 44.46 Vested (16,000 ) $ 13.48 Forfeited (33,324 ) $ 23.20 Nonvested at June 30, 2015 630,858 $ 30.55 The Company recognized compensation expense related to restricted stock, which is included in other operating expenses, of $967 and $1,381 for the three months ended June 30, 2016 and 2015, respectively, and $1,948 and $2,789 for the six months ended June 30, 2016 and 2015, respectively.

Commitments and Contingencies	Note 13 — Commitments and Contingencies Obligations under Multi-Year Reinsurance Contracts As of June 30, 2016, the Company has contractual obligations related to multi-year reinsurance contracts. These contracts were effective June 1, 2016 and may be cancelled only with the other party’s consent. The future minimum aggregate premiums payable to these reinsurers is $19,400 due in each of the twelve-month periods following June 30, 2016 and 2017. Capital Commitment As described in Note 3 — “Investments” under Limited Partnership Investments Premium Tax In September 2013, the Company received a notice of intent to make audit adjustments from the Florida Department of Revenue in connection with the Department’s audit of the Company’s premium tax returns for the three-year period ended December 31, 2012. The auditor’s proposed adjustments primarily related to the Department’s proposed disallowance of the entire amount of $1,754 in Florida salary credits applicable to that period. The proposed adjustment, which included interest through September 10, 2013, approximated $1,913. To resolve the matter, the Company entered into negotiations with the Department and reached an agreement in principle whereby certain of the Company’s subsidiaries would individually file and pay state reemployment taxes plus interest covering the periods under audit through the second quarter of 2014. Such filings were expected to yield a refund of reemployment taxes paid by the Company. In December 2015, the Department issued its Notice of Decision indicating the Company owed approximately $38 in full settlement of the premium tax and related interest, which the Company paid in February 2016. The Company received refunds totaling $57 related to its reemployment tax filings specific to the period for which the Company was required to file and pay the subsidiary reemployment tax returns as part of the negotiated settlement. As a result, the Company realized a net benefit of $19. Management believes this matter is fully resolved.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited, consolidated financial statements for HCI Group, Inc. and its 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, 2016 and the results of operations and cash flows for the 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, 2016. 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, 2015 included in the Company’s Form 10-K, which was filed with the SEC on March 4, 2016. 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 for reinsurance contracts with retrospective provisions, deferred income taxes, 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.
