Homeowners insurance in Wisconsin

The home insurance market in Wisconsin

Wisconsin homeowners paid $2.71 billion in homeowners premiums in 2025, according to NAIC market share data. These are the 10 largest insurance groups by 2025 direct premiums written:

Wisconsin is one of the few states where State Farm is not the largest home insurer. Madison-based American Family leads with 21.01%, and two more home-state mutuals make the top 10: Acuity of Sheboygan (55th nationally) and West Bend (71st). Below the top two the market is wide open; the top 10 together hold about 75% of premiums. Auto-Owners, Erie, Acuity and West Bend all sell through independent agents, so one agent can often quote several of them.

What drives home insurance costs in Wisconsin

By NAIC's average-premium data, Wisconsin is the cheapest state in the country for homeowners insurance. The average HO-3 premium was $923 in 2023, about 47% below the national $1,737 and the lowest of 51 (our ranking of NAIC's table). Wisconsin also had the lowest average across all dwelling and owner-occupied forms ($968) and the lowest condo (HO-6) average ($331).

Cheap on average does not mean cheap after a storm. Severe convective storms (hail, straight-line winds and tornadoes) are the recurring threat. On July 28, 2026 Commissioner Nathan Houdek urged residents to document damage after storms the day before brought high winds, tornadoes and hail, especially to eastern Wisconsin. Water is the other big risk. OCI's own disaster page says Wisconsin has seen more intense and frequent heavy rains in recent years, with flooding, washed-out roads and failed dams. See hail damage claims: roofs, siding and windows and severe convective storms and rising premiums.

The clearest recent example was the Milwaukee-area flood of August 2025. Up to 14.6 inches of rain fell on August 9 and 10, according to the Wisconsin Policy Forum, and FEMA approved a major disaster declaration (DR-4892) with individual aid for Milwaukee, Washington and Waukesha counties. OCI reminded homeowners that their policies do not typically cover flood, and that FEMA may ask for proof of a denied homeowners claim before paying aid.

Deductibles and coverage rules to know

Wisconsin has no hurricane or named-storm deductible rules. Wind and hail deductibles, including percentage deductibles, are set by your policy, so check the declarations page before storm season. Run your numbers through the hurricane and percentage deductible calculator.

Wisconsin's termination law (Wis. Stat. §631.36) gives you these protections:

• Midterm cancellation. After a new policy has been in force 60 days, or once it has renewed, the insurer can cancel only for nonpayment, material misrepresentation, a substantial change in the risk or a substantial breach of the policy, with at least 10 days' written notice.
• Nonrenewal. You get at least 60 days' notice before the policy expires.
• Reasons. A cancellation or nonrenewal notice must state "with reasonable precision" the facts behind it, and must tell you how to apply to the Wisconsin Insurance Plan; otherwise it is not effective.
• Worse terms at renewal. For personal lines policies, new terms or a higher premium take effect at renewal only with 45 days' notice. A late notice delays the change until 45 days after it is sent, and you may cancel in the meantime. This notice is not required for an increase under 25% that applies to the whole class of business.

Flood and other gaps

FEMA data show 10,804 NFIP policies in force in Wisconsin as of September 30, 2026. Milwaukee County has 1,455 of them (13.5%) and Dane County 964 (our calculations from FEMA's community figures). The August 2025 flood exposed how thin that is: of 27,134 Milwaukee County flood damage claims submitted to FEMA, only 518 (1.9%) came from households with flood insurance, the Wisconsin Policy Forum reported in July 2026. Federal aid to individuals topped $210 million across the three counties by June 2026. Remember the NFIP's 30-day waiting period.

If you can't find coverage

The Wisconsin Insurance Plan is the state's FAIR plan, a mandatory risk-sharing facility of the insurers licensed to write property coverage here (Wis. Admin. Code Ins 4.10). Town mutuals are not members. It offers two residential programs, both settling losses at actual cash value, never replacement cost:

• Homeowner program. Uses the ISO modified coverage form (HO 00 08) for an owner-occupied one- or two-family principal residence with a market value of $350,000 or less. The dwelling limit runs from $15,000 to $350,000, with personal property at 50%, other structures at 10%, liability at $100,000 and medical payments at $1,000. Deductibles rise with the dwelling limit, from $250 below $75,000 to $2,500 at $250,000 and up.
• Dwelling program. Uses the DP 00 01 basic form for one- to four-family homes, including rentals, seasonal homes, condo units and houses under rehabilitation, up to $350,000 on the dwelling and $175,000 on contents. Wind, hail and vandalism cost extra, and there is no liability coverage.

Active farms are ineligible. A licensed agent must submit your application with proof that another insurer canceled or rejected you within the past six months and a deposit of at least 20% of the annual premium; an inspection follows within two to four weeks. After four years the plan nonrenews, and you must shop the standard market again before reapplying. Beyond these limits, look at surplus lines home insurance when standard carriers say no. See FAIR plans explained: the insurer of last resort for homes.

Claims rules and deadlines

Wisconsin's prompt-pay statute (§628.46) makes a claim overdue if it is not paid within 30 days after the insurer receives written notice of the covered loss and its amount, and no earlier than 30 days after it receives the proof of loss. Overdue amounts earn 7.5% simple annual interest. Under the unfair claim settlement rule (Ins 6.11), "promptly" means responsive action within 10 days of receiving a claim communication.

The suit deadline is short. An action on a fire insurance policy, which includes property riders covering loss "from any cause" and separate windstorm or hail policies, must be filed within 12 months after the inception of the loss (§631.83). That period is tolled while an appraisal runs, and you cannot sue until 60 days after filing proof of loss unless the insurer denies payment sooner. See deadlines to sue over a home insurance claim.

Watch who negotiates for you. In October 2025 OCI imposed $6,000 in forfeitures on a contractor it found was acting as a public adjuster, using assignments of benefits that violated state law. A public adjuster in Wisconsin may not take an assignment of your claim proceeds or require you to use a particular contractor.

Discounts and mitigation programs

Wisconsin has no state mitigation grant, and it was not among the nine states IBHS listed in July 2025 as running FORTIFIED grant programs. OCI's Stronger Wisconsin campaign promotes mitigation and adequate coverage instead. Ask your insurer about credits for impact-resistant roofing, which can pay off in hail country; see Impact-resistant (Class 4) roofs and hail discounts.
