Do I Need Building Insurance for My Home?
No state requires it, but your mortgage lender will, and most require dwelling coverage equal to the home's rebuild cost before closing.

What your lender requires
Your lender sets the minimum, usually dwelling coverage equal to the loan amount or the home's rebuild cost, whichever applies under your mortgage agreement. They need proof of this, called a binder or declarations page, before closing can happen.
Rebuild cost, not sale price
Dwelling coverage pays to rebuild the house, not what you paid for it or what it would sell for. Land value, location and market demand don't factor into rebuild cost, which is usually lower than the purchase price but not always.
Your closing date deadline
The title company or closing attorney will ask for proof of coverage, often a week or more before closing. Buying a policy takes time to set up, so starting early avoids a scramble that could delay signing.
How escrow pays for it
If your lender escrows your insurance, your mortgage payment includes a portion set aside for the annual premium, which gets paid out when it's due. Your first year's premium is often collected upfront at closing before escrow takes over.
Worth comparing before you commit
Lenders set a minimum, but the policy that meets it isn't the same at every insurer. Comparing rebuild cost estimates and premiums before closing can mean the difference between adequate coverage and paying more than you need to.
What else the policy needs to cover
Dwelling coverage is the part your lender checks, but it's not the whole policy. Your homeowners policy also covers personal property, which is everything you own inside the house, liability if someone gets hurt on your property, and additional living expenses if the house becomes unlivable after a covered loss. None of these show up on your lender's minimum requirement, but leaving them too low is how people end up underinsured after a fire or a burst pipe.
Personal property coverage is usually a percentage of your dwelling coverage, often set automatically by the insurer unless you ask to change it. If you have a lot of valuable items, electronics, jewelry, instruments, that default amount might not be enough, and some policies cap what they'll pay for specific categories unless you add a rider or schedule the item separately. Walking through what you own before you buy the policy, even roughly, tells you whether the standard amount fits.
Liability coverage protects you if someone is injured on your property and sues, or if you accidentally damage someone else's property. Most policies start around a baseline amount, but if you have significant savings or assets to protect, raising that limit costs little compared to what a lawsuit could cost you. This is also where umbrella policies come in for people who want more protection than a standard homeowners policy offers, though that's a separate purchase.
Then there's the deductible, the amount you pay out of pocket before coverage kicks in on a claim. A higher deductible lowers your premium, but it also means more cash needed upfront if something happens. Since this is your first policy, it helps to pick a deductible you could actually afford to pay tomorrow, not just the number that makes the quote look cheapest. Some policies also carry a separate, higher deductible for wind or hail damage, which your declarations page will spell out once you have it.
What about floods and earthquakes?
A standard homeowners policy, the one your lender is asking about, does not cover flood damage. It's excluded, not a gray area. If the home sits in a flood zone, your lender will likely require a separate flood insurance policy before closing, usually through the National Flood Insurance Program or a private flood insurer. Even outside a mapped flood zone, flooding can still happen, and some buyers choose the coverage anyway since it's not part of what dwelling coverage pays for.
Earthquake damage works the same way. It's typically excluded from a standard policy. If you want protection against it, that's a separate policy or an endorsement added to what you already have. Whether this matters depends on where the house is. Your lender won't require it unless you're in a region where earthquake risk is part of the underwriting picture, but it's worth asking about if you're not sure.
A few other things catch first-time buyers off guard. Sewer backup, sump pump failure and mold are often excluded or limited unless you add coverage for them specifically. None of these show up as a lender requirement, which is part of why people skip past them. The lender cares about the dwelling being insured enough to protect the loan. Whether the rest of the house, and what's in it, is actually covered the way you'd expect after a loss is a separate question.
Before closing, it's worth asking what a policy does and doesn't cover beyond the dwelling number, especially for the risks tied to where the house actually sits. A flood zone lookup takes a few minutes and tells you whether that conversation is urgent or not. Getting this right before the policy is in place costs nothing extra. Finding out after a loss that something wasn't covered costs a lot more than the premium would have.
Before you lock in a policy
Check your closing date, then ask how soon that insurer can send a binder. Pull up your declarations page draft and confirm the dwelling amount matches rebuild cost, not the purchase price.
