Do Insurance Companies Check for Building Permits?
Yes, often after a claim, when permit records show unpermitted work, insurers can deny the claim or drop the policy.

When permits come up on a claim
Permits usually surface when something goes wrong, not before. A pipe bursts behind a wall someone finished without a permit, or an electrical fire starts in wiring a previous owner added without inspection. The adjuster pulls county records as part of looking into the claim. If the work was never permitted, the insurer can argue it was done outside code and deny that part of the claim. It's less about the permit itself and more about what its absence suggests. Nobody signed off on the wiring, the plumbing, or the structural work behind it. This is also why some non-renewals name unpermitted additions or renovations as the reason. If this applies to your house, your county's permit office can tell you what's on file, and your declarations page will show whether past work was disclosed when the policy was written.
A policy that won't cover unpermitted work is a gap you're carrying now
If past work on your house was never permitted, one insurer may already have used that against a claim. A new policy can be checked and set up with that disclosed upfront.
What about work done by a previous owner
If you bought the house with the addition, the finished basement, or the rewired garage already in place, the lack of a permit is not something you did. It is still something the insurer looks at the same way. A claim adjuster does not ask who pulled the permit, only whether one exists. If the seller's disclosure mentioned the work, or the inspection report flagged it, that paper trail matters now more than it did at closing.
A title search does not catch this. Neither does a standard home inspection, which looks at condition, not permit history. The only way to know what's on file is to check with the county or city permit office directly, using the address. Most offices let you search online or over the phone, and it costs nothing to look. If something was done without a permit, you'll find out before an insurer does, which gives you time to decide what to do about it.
Getting a permit after the fact, sometimes called a retroactive or after-the-fact permit, is possible in many places. It usually means an inspector comes out to look at the work as it stands now, and depending on what they find, you may need to open up walls or make changes to bring it up to code. It costs money and it's not guaranteed to pass. But it closes the gap that would otherwise sit under your policy indefinitely.
Not every unpermitted item is worth chasing down. A permit for a water heater replaced ten years ago matters less than one for a structural wall that was moved or a panel that was rewired. When comparing policies, knowing which of these exist on your house, and disclosing them upfront, is what keeps a future claim from turning into a denial.

Before you request quotes
Call your county permit office and check your address against what's on file. If anything was done without a permit, disclose it when you apply so a new policy is written with that known, not discovered later during a claim.
