Home Insurance in Illinois: What It Costs and What Actually Covers You

  • Illinois averages about $2,697 a year for $300,000 of dwelling coverage with a $1,000 deductible — slightly below the roughly $2,872 national average at that same tier, which makes Illinois an ordinary-cost state on the headline.
  • The headline is not what you will actually pay on a claim. In its 2025 Illinois rate filing, State Farm imposed a MINIMUM 1% wind/hail deductible on Illinois homeowners policies — customers who did not already meet it were automatically billed at 1%.
  • On a $300,000 dwelling limit, a 1% wind/hail deductible is $3,000 and a 2% is $6,000 — three to six times the $1,000 shown on your declarations page, on precisely the claim an Illinois homeowner is most likely to file.

Illinois is not a hurricane state, and it is not an expensive state. At $2,697 a year for $300,000 of dwelling coverage, it sits slightly below the roughly $2,872 national average published on the same tier. If you stopped reading here you would conclude that Illinois home insurance is unremarkable.

The number that makes Illinois specific is not the premium. It is this: in its 2025 Illinois rate filing, State Farm stated that Illinois has had more hail damage than any state except Texas, and that catastrophe losses exceeded its annual provision in 13 of the last 15 years.

The filing did two things about that. It took an average 27% rate increase — 28.3% on homeowners specifically — effective July 15, 2025 for new business and August 15, 2025 for renewals. And it imposed a minimum 1% wind/hail deductible on Illinois homeowners policies, with customers who did not already meet that minimum automatically billed at 1%.

Because State Farm insures roughly one in three Illinois homeowners, that one filing converted the percentage wind/hail deductible from a niche structure into a mainstream Illinois one. Other carriers use the same approach.

Here is what that means in practice. Your declarations page probably says $1,000. On a hail claim — the claim an Illinois homeowner is most likely to file — the number that applies is probably $3,000, and on many policies $6,000. Nothing about that is hidden or improper. It is written on the policy. It is simply not the number most people think they have.

This guide works through what a policy costs here, which deductible governs which loss, the Illinois-specific gaps in coverage that a generic guide will not mention, how much dwelling coverage you actually need at Illinois construction costs, and what the FAIR Plan will and will not do for you.
