Home inspectors run into insurance in two ways: as a licensing requirement and as a claim. The two are connected but not the same, and treating the first as the whole story is where inspectors get caught. Some states require inspectors to carry E&O or general liability for licensure, with specific minimum limits, and others do not, and the rules change. But the claim that actually arrives, a missed or under-reported defect found after closing, is an E&O matter regardless of what the state requires. Inspector coverage has to satisfy both.
The requirements vary, so verify
State requirements for home inspector insurance are genuinely inconsistent. Some states mandate E&O, some mandate general liability, some set minimum limits, and some leave it to the inspector. Because these rules differ and are updated, the right move is to confirm your state’s current requirement rather than rely on what was true a few years ago or what a colleague in another state carries. Meeting the requirement is the floor, not the finish line.
The claim that drives E&O
The signature inspector claim is simple: you missed a defect, or did not report it clearly enough, and it surfaced after the sale as a demand letter. That is an E&O claim, and it is why E&O is the core of inspector coverage even where the state does not require it. General liability covers an injury or damage on site; it does not respond to a professional claim that you missed something. Most inspectors carry both.
Why the agreement is not enough
Inspectors often lean on a strong pre-inspection agreement and assume it solves the liability. It helps, it can limit scope and set expectations, but courts do not always enforce limitation-of-liability clauses as written, and a client can still sue. The agreement and the insurance are partners, not substitutes. Relying on the contract alone is one of the most common inspector mistakes, and it tends to be discovered at the worst time.
Mind the ancillary services
Ancillary services, radon, sewer scopes, mold, thermal imaging, water testing, are a smart revenue lever and a quiet liability lever. A claim arising from one of them can be excluded if your E&O was written only for standard home inspections. Every time you add a service, the coverage has to be confirmed to contemplate it. Matching the E&O to your full scope of work is the single most overlooked step as inspectors grow.
Match the coverage to the work and the state
The right approach is E&O sized to your volume and full service scope, general liability for on-site risk, and confirmation that the policy meets your state’s licensing terms. A coverage review or the risk assessment checks all three, so a missed-defect claim, or a licensing audit, does not find a gap the state minimum and a good contract left open.
