Homeowners insurance in Michigan

The home insurance market in Michigan

Michigan homeowners paid $4.74 billion in homeowners premiums in 2025, according to NAIC market share data. These are the 10 largest insurance groups by 2025 direct premiums written:

Michigan's market is unusually home-grown. Lansing-based Auto-Owners writes almost as much as State Farm, the Dearborn-based Auto Club Group is third, and Farm Bureau Insurance of Michigan is sixth here though only 76th nationally. Those three Michigan companies together write about 36% of the state's premiums. Auto-Owners and Farm Bureau sell through agents, so in much of the state an independent or Farm Bureau agent is where a quote starts.

What drives home insurance costs in Michigan

Michigan is one of the cheaper states to insure a house. NAIC's average HO-3 premium was $1,110 in 2023, about 36% below the national $1,737 and the 5th lowest among the states and D.C. by our ranking of NAIC's table.

With no hurricane coast, Michigan's big loss events are storms and water. In March 2025 an ice storm across northern Lower Michigan led the governor to declare a state of emergency for 10 counties, later expanded, and a federal disaster declaration followed on July 23, 2025. In March 2026 deadly tornadoes hit southwest Michigan, and more flooding and tornadoes followed in April. Water in the basement after these storms is where coverage is most often misunderstood (see below).

Michigan also polices how insurers price. DIFS said in a March 2024 bulletin that price optimization, varying premiums by a customer's willingness to pay more, is unfairly discriminatory, and in September 2026 Governor Gretchen Whitmer signed Senate Bill 1013, which writes that ban into law. Insurers may use credit-based insurance scores to rate a home policy but not as any part of a decision to deny, cancel or nonrenew it (MCL 500.2153).

Deductibles and coverage rules to know

Michigan has no hurricane deductible law. Some insurers file a separate wind or hail deductible, sometimes a percentage of Coverage A (dwelling): say your Coverage A is $300,000 and your wind/hail deductible is 1%, and a hail-damaged roof costs you the first $3,000. Check your declarations page and try the hurricane and percentage deductible calculator; wind and hail deductibles explained explains the difference from a flat deductible.

The Essential Insurance Act gives Michigan homeowners unusual protection. An insurer may not refuse to insure, refuse to renew or limit coverage for an "eligible person" (an owner-occupant or tenant of a house, condo or apartment, or an owner-occupant of a building with up to four units) except under written underwriting rules that it applies uniformly and files with DIFS (MCL 500.2117, 500.2119). Those rules can rest only on listed grounds:

• Physical condition, measured against a specific housing or safety code or similar standard, and "without regard to the age of the structure." A certificate of code compliance from your local government creates a presumption the house qualifies.
• Claim history at renewal, limited to claims from your own negligence, failure to fix a condition after written notice, or three paid property claims in three years above dollar thresholds the statute sets and adjusts for inflation every six years.
• Other listed reasons, such as an arson conviction or a claim denied for arson or fraud in the past five years, a home vacant more than 60 days with intent to keep it vacant, or refusing to insure to at least 80% of replacement cost.

To cancel or nonrenew for any reason but nonpayment, the insurer must mail or deliver written notice at least 30 days ahead, giving each specific reason; a notice in the first 55 days of a new policy can take effect after 20 days (MCL 500.2123). Moving you to an affiliate at a higher rate, or renewing on less favorable terms you did not ask for, counts as a termination too (MCL 500.2104).

Flood and other gaps

Standard homeowners policies exclude both flood and water that backs up through sewers or drains unless you buy an endorsement; the MBPIA's own forms exclude backup too. DIFS warns homeowners to describe a loss as "water damage" rather than "flooding" when they call it in, because rain intrusion, a sewer backup or a failed sump pump may be covered when true flood is not. See water backup and sewer backup coverage.

If a municipal sewer system backs up into your basement, Michigan law lets you seek compensation from the government agency, but only if you send it written notice within 45 days of discovering the damage, with your name, address, phone, the property address, the discovery date and a brief description (MCL 691.1419). File that notice even while your insurance claim is open.

FEMA data show about 19,000 NFIP flood policies in force in Michigan as of September 30, 2026, about 20% of them in Wayne County (our calculations from FEMA's community figures). Do not assume a low-risk map zone means no risk: FEMA says nearly one-third of NFIP claims from 2014 to 2024 came from outside high-risk flood areas. See NFIP flood insurance explained.

If you can't find coverage

The Michigan Basic Property Insurance Association is Michigan's FAIR plan, organized under 1968 PA 262 and operating since October 21, 1968. It is a not-for-profit association of all insurers writing similar coverage in Michigan, which share its operating deficits through assessments. It writes DP-1 dwelling fire coverage at actual cash value and HO-2, HO-3, HO-4 and HO-6 homeowners forms, including a repair-cost HO-2, with optional water damage endorsements of $2,500 or $5,000. You must apply through a licensed agent. Before you settle for it, remember that the Essential Insurance Act limits why a private insurer can turn you down, and a company that declines you must give each specific reason (MCL 500.2122); ask which filed underwriting rule you failed. See FAIR plans explained: the insurer of last resort for homes.

Claims rules and deadlines

Under MCL 500.2006, if your claim is not settled within 30 days, the insurer must tell you in writing what it needs as satisfactory proof of loss. If the insurer pays your claim more than 60 days after it receives satisfactory proof of loss, it owes you 12% simple interest from day 60, paid with the claim; the interest is not due if you turned down an offer and later recover no more than it. Michigan's required fire policy provisions also include an appraisal process for disputes over the amount of loss, with an umpire picked by a circuit judge if the two appraisers cannot agree; see the appraisal clause: settling a claim value dispute.

Your policy must give you at least one year after the loss to sue, or a longer period if the policy says so, and that clock stops from the time you report the loss until the insurer formally denies it (MCL 500.2833(1)(q)). Write down the date of any denial letter.

Discounts and mitigation programs

Michigan has no state mitigation grant or discount mandate that we found, and it was not among the nine states IBHS listed in July 2025 as running FORTIFIED grant programs. That may change: a three-bill "Strengthen MI" package introduced in July 2026 (SB 1128–1130) would create a FORTIFIED roof grant program and, under SB 1129, require an actuarially justified discount for FORTIFIED-certified homes on policies issued or renewed after 2027. As of October 24, 2026 the bills were still in the Senate committee on Finance, Insurance, and Consumer Protection (SB 1129). Roof, alarm, water-sensor and bundling discounts are set by each insurer; see homeowners insurance discounts to ask about.
