What Is Not Covered by a Homeowners Policy?
Flood and earthquake damage, routine wear, pest infestations, and sewer backups usually aren't covered unless you add separate coverage.
Free to compare
Your lender needs proof of coverage before closing, but the policy itself won't protect you from everything that can go wrong with the house. Flood and earthquake coverage have to be bought separately, often from a different insurer. If the house sits in a flood zone or an earthquake-prone area, ask about that now rather than after you move in. Mold from a slow leak, termite damage, an aging roof, those fall on you to maintain. Your declarations page lists exactly what's included, and it's worth reading before you sign anything.
Coverage gaps cost more after closing
Two policies at the same price can leave different gaps. Comparing what each one actually covers, not just the premium, is how you find out before the exclusions become your problem.
What else won't be covered, and how do you find out before closing
Beyond flood, earthquake, and wear and tear, there are other gaps that catch new homeowners off guard. Damage from a lack of maintenance is almost never covered, so if the home inspector flagged an aging roof or a slow plumbing leak and you don't deal with it, any damage that follows traces back to neglect, not a covered event. Sewer and drain backups usually need an endorsement added to the policy, it's not automatic. Water damage from a specific burst pipe is typically covered, but gradual seepage over time is not, and insurers draw that line carefully when they look at a claim.
Business property and high-value items also have limits most people don't expect. If you work from home and keep equipment there, your homeowners policy likely caps business property coverage at a low amount, sometimes a few thousand dollars. Jewelry, art, and collectibles often have their own sub-limits too, so a ring worth more than that limit needs to be scheduled separately on the policy to be fully covered. None of this shows up unless you read the declarations page line by line or ask directly.
Detached structures like a shed, detached garage, or fence are usually covered under a separate part of the policy, often at a percentage of your dwelling coverage rather than full replacement value. If the property has any of these, confirm the amount is enough to rebuild them, not just repair. Liability coverage has limits too, and if someone is hurt on the property and sues for more than the policy covers, the difference comes out of pocket unless an umbrella policy is in place.
The way to catch these gaps before closing is to ask for the specific exclusions list, not just the coverage summary, and compare it across every quote. One insurer's standard policy might include water backup coverage as a low-cost add-on, while another charges significantly more or doesn't offer it at all. Since the lender only requires proof that a policy exists and meets the loan amount, nobody is checking whether it actually covers the risks specific to this house. That part is on you, before the closing date arrives, not after something happens.
Does the coverage amount actually match what the house would cost to rebuild
Dwelling coverage is supposed to equal what it costs to rebuild the house, not what it sold for. Those two numbers are often far apart. A house might close at $450,000 because of the lot, the location, and the market, while the actual cost to rebuild the structure if it burned down is $320,000 or $500,000 depending on materials, labor costs in the area, and the size of the house. If the insurer sets dwelling coverage based on the sale price instead of a real rebuild estimate, the policy can end up underinsured from day one.
Most insurers use a formula based on square footage, construction type, and local building costs to arrive at a dwelling coverage number. It is worth asking how that number was calculated rather than accepting it as given. If the house has upgrades the formula would not know about, a renovated kitchen, custom finishes, an addition, those need to be mentioned specifically or the rebuild estimate will fall short of what it would actually take to replace them.
Inflation during construction is another piece people do not think about until there is a claim. Rebuilding costs after a major disaster often run higher than normal because of a surge in demand for contractors and materials all at once. Some policies include extended replacement cost coverage, which pays a percentage above the stated dwelling limit to cover that kind of spike. Without it, a policy that looked sufficient on paper can leave a real gap between what is paid out and what it costs to actually finish rebuilding.
This is worth settling before closing, not after move-in, because the dwelling coverage number is what the lender is checking against the loan amount in the first place. A policy that meets the loan requirement is not the same as a policy that covers a full rebuild. Asking for the rebuild cost estimate behind the dwelling number, and comparing it against a contractor's rough sense of local building costs, is the only way to know whether the coverage matches the house instead of just the mortgage.
Before you sign anything
Pull the exclusions list, not the summary, and check it against the dwelling coverage number. Confirm how that rebuild estimate was calculated, then compare quotes on what's actually covered.
