Illinois Home Insurance Hikes: What Buyers Should Do
Homeowners insurance in Illinois has become one of the biggest surprise costs in buying or owning a home, and it is not getting cheaper. This piece explains why premiums here keep climbing, how that hits your monthly payment, and what buyers and sellers in Bartlett, Elgin, Schaumburg and the surrounding suburbs can actually do about it.
If you’ve opened a renewal notice lately and done a double take, you’re in good company. Insurify estimated Illinois home insurance costs would rise a record 27% in 2025, and State Farm, the state’s largest home insurer, has continued to point to severe-weather claims as the reason it needs more money from Illinois policyholders. A premium that used to be a rounding error in the mortgage payment is now a line item people negotiate over.
Why Illinois Gets Hit So Hard
The short version: hail, wind, and a regulatory setup that lets insurers move fast.
The weather. Chicagoland doesn’t get hurricanes, but we get something insurers arguably dread more on a year-to-year basis: frequent, widespread convective storms. A single hail event across the northwest suburbs can mean thousands of roof claims in Streamwood, Hanover Park and Carol Stream in one afternoon. Those claims add up, and insurers price the next year accordingly.
The rules. Illinois is unusual. For homeowners insurance, the state relies largely on market competition instead of requiring insurers to get prior approval for their rates. That means a carrier can raise rates without the Illinois Department of Insurance signing off first, which is part of why Illinois increases have been so steep compared with states that review rates up front. Gov. Pritzker backed legislation in 2024 to give the Department authority to review and reject excessive homeowners rate hikes; it stalled in Springfield, and as far as we can tell the basic framework hasn’t changed. If that changes, we’ll write about it.
Construction costs. Roofs, siding, and labor all cost more than they did five years ago. Insurers have to set dwelling coverage based on what it costs to rebuild, not what you paid for the house, and rebuild costs have climbed.
What It Does to Your Monthly Payment
Most buyers with a mortgage pay insurance through escrow, which means a premium increase doesn’t show up as a separate bill. It shows up months later as an escrow shortage letter and a higher monthly payment. Your servicer reviews the escrow account once a year; if insurance (or property taxes, which in DuPage, Cook and Kane counties are already doing plenty of damage) went up, you’ll either pay the shortage in a lump sum or have it spread across the next 12 payments, on top of the new, higher monthly amount. That double hit is what catches people off guard.
For condo and townhome owners there’s a second layer: the association’s master policy. When the HOA’s premium jumps, it flows through to your monthly assessment, even if your own HO-6 policy barely moved.
If You’re Buying
- Get a real quote during attorney review, not at closing. Your lender needs proof of insurance anyway. Get quotes early enough that a surprise number can still factor into your decision, or your negotiation.
- Ask about the roof’s age, then ask the agent what that does to your quote. Many carriers now price heavily on roof age, and some will only cover an older roof at actual cash value (depreciated) rather than replacement cost. On a 20-year-old roof, that difference is the whole roof.
- Look at the wind/hail deductible separately. More policies carry a percentage deductible for wind and hail, often 1% or 2% of dwelling coverage. On a $400,000 dwelling limit, 2% is $8,000 out of pocket before coverage kicks in for the most common claim in our area.
- Ask for a sewer backup endorsement. It’s usually not included by default, and in a lot of suburban basements it’s the claim that actually happens. Flood is a separate policy entirely, through the NFIP or a private carrier.
- Request the CLUE report if you can. Prior claims on the property can follow the house, not just the owner. A seller can pull their own report for free.
If You’re Selling
Buyers are now pricing insurance into their offers, whether they say so or not. A newer roof isn’t just a nice line in the listing anymore; it’s a lower premium for the next owner, and that’s a real selling point. If you replaced the roof after a hail claim, keep the paperwork handy. If the roof is near the end of its life, expect it to come up during inspection negotiations, and know that the buyer’s insurance quote may be what’s driving the request.
Under the Illinois Residential Real Property Disclosure Act (765 ILCS 77), you already have to disclose known material defects like roof leaks. Being upfront about roof age and condition tends to make the insurance conversation easier, not harder.
If You’re Staying Put
Shop your policy every year or two; loyalty isn’t rewarded the way it used to be. Bundling home and auto still helps with most carriers. Raising your all-perils deductible can lower the premium meaningfully if you have cash reserves to cover it. And think twice before filing small claims. A $1,500 claim can cost you more than that in higher premiums over the following years.
It’s also worth a quick check that your dwelling coverage actually reflects rebuild cost. Being underinsured after a total loss is a far worse problem than an annoying premium.
The Bottom Line
Insurance used to be the part of homeownership you set once and forgot. In Illinois right now, it’s a number worth checking before you write an offer, before you list, and every time the renewal shows up. If you’re thinking about buying or selling in Bartlett, Bloomingdale, Elgin or anywhere nearby and want a second set of eyes on how insurance and taxes affect the real monthly cost, Team Goddard is happy to walk through it with you, no pressure attached.
