For the house itself, you generally need enough dwelling coverage to rebuild it, not what it would sell for. Regulators such as the NAIC say the limit should be based on the estimated cost to rebuild, which leaves out the value of the land. You also need to think about your belongings, liability and living costs after a loss. Your lender may set a minimum, but it's usually just a starting point.
Key takeaways
- Base your dwelling limit on the cost to rebuild, not the purchase price or market value. Land isn't destroyed in a fire.
- Many insurers expect at least 80% of replacement cost, and falling short may reduce what they pay on a claim.
- Construction costs change, so review your limit each year at renewal.
- Also check coverage for belongings, liability, other structures and living expenses.
- Floods and earthquakes need separate coverage.
Market value is not rebuild cost
This is the most common mistake. Your home's market value includes the land, the neighborhood and the real estate market. Rebuilding cost depends on materials, labor, local building codes, and the size and features of the house. The two numbers can be far apart. A house in a pricey area may cost less to rebuild than it would sell for, while a house in a cheaper area with custom features may cost more.
The NAIC explains that your coverage limit should be based on the estimated cost to rebuild, not the purchase price or current market value. The Texas Department of Insurance says the same, noting that appraised value includes land and market conditions while insured value reflects the cost to rebuild or replace the home.
The six main coverages to size
A typical homeowners policy has several limits. Here is how each is set and what to think about:
| Coverage | What it protects | How the limit is usually set |
|---|---|---|
| A. Dwelling | The house and attached structures | Estimated cost to rebuild |
| B. Other structures | Detached garage, shed, fence | Often a percentage of Coverage A. Increase if you have costly outbuildings |
| C. Personal property | Furniture, clothing, electronics | Often a percentage of Coverage A. Compare to a home inventory |
| D. Loss of use | Hotel and extra living costs after a covered loss | Often a percentage of Coverage A, sometimes with time limits |
| E. Personal liability | Lawsuits for injury or damage you cause | Chosen by you, in set steps |
| F. Medical payments to others | Minor injuries to guests | Smaller set limits |
Percentages for B, C and D vary by insurer, so check your declarations page.
How to estimate your dwelling limit
Start with the square footage and quality of your home
Rebuilding costs depend on square footage and on features, such as a custom kitchen, hardwood floors, a complex roofline or a basement. A "cost per square foot" is just a starting point, since it varies a lot by region and quality.
Use your insurer's estimate, and question it
Insurers often generate a replacement cost estimate with software when you apply. Ask what details they used, such as year built, square footage, number of stories, roof type, and finishes. Correct anything that's wrong, and mention upgrades. A mismatch can mean you're under-insured without knowing it.
Get another opinion
A contractor or a professional appraiser who estimates replacement cost can give you a second view. A market appraisal from a mortgage process is not the same thing and usually doesn't tell you the rebuilding cost.
Review it every year
Building costs and codes change. The Texas Department of Insurance notes that building costs can change over time, which means a limit set a few years ago may now be too low. Many policies include an inflation guard that increases the limit automatically, but check how it works.
The 80% rule and coinsurance
Many insurers require you to insure your home for at least 80% of its replacement cost, and some require 100%. If you carry less, the insurer may reduce what it pays on a claim, even a partial one. The NAIC gives an example: if rebuilding costs $200,000 but the policy covers only $120,000, the insurer might pay only 60% of the repair cost, minus the deductible. The numbers are illustrations, and the details depend on your policy.
Watch out: Being under-insured can hurt even on small claims, because a shortfall can reduce the payment on partial losses, not just total losses.
Extra protection for rebuild costs
Some options can help if rebuilding costs more than expected. Triple-I describes two:
- Extended replacement cost, which pays a set percentage above your limit, generally 20 to 25 percent.
- Guaranteed replacement cost, which pays what it costs to rebuild your home as it was, even if it exceeds the limit. It may not be available for older homes or in all states.
An ordinance or law endorsement can also help pay for rebuilding to current building codes, which standard policies don't generally cover. These options may cost more, and availability varies by insurer and state.
How the claim is paid also matters. See replacement cost vs. actual cash value.
Sizing coverage for belongings
Many people underestimate what they own. Walk through each room and estimate what it would cost to replace everything. A home inventory makes this easier and speeds up claims later. Our guide on how to create a home inventory shows how.
- Check the sublimits for jewelry, collectibles, firearms and cash. They are often low.
- Decide whether your belongings are covered at replacement cost or actual cash value.
- Think about scheduling high-value items separately.
How much liability coverage?
Personal liability pays if someone is hurt on your property or you cause damage to others, up to the limit. Insurers offer a range of limits, and higher limits are often available for an added cost. Factors people often weigh include savings and assets, a pool or trampoline, or a dog. If your assets exceed your liability limits, you may want to explore options for higher limits, including a personal umbrella policy. See personal umbrella insurance explained and dog bite liability and home insurance.
Risks the policy doesn't cover
A standard policy excludes flood and earthquake. FEMA notes that most homeowners insurance doesn't cover flood damage. If you live in an area with these risks, look at flood insurance and earthquake insurance. Wind and hail deductibles may also work differently, as explained in home insurance deductibles explained.
A simple checklist
- Find your declarations page and note each limit and deductible.
- Ask your insurer how it estimated the replacement cost, and review the inputs.
- Compare your dwelling limit with an independent estimate if you can.
- Review your belongings list and high-value items.
- Think about your liability exposure and whether more coverage makes sense.
- Check for flood, earthquake and other gaps.
- Repeat the review every year and after renovations.
When you compare quotes, use the same limits and deductibles with each insurer so the prices are comparable.
Frequently asked questions
Should my coverage match my mortgage balance?
Not necessarily. Lenders want to protect their loan, but the right limit for you is based on rebuild cost. Your balance can be higher or lower than that.
Does dwelling coverage include the land?
No. Land isn't normally destroyed or covered by the dwelling limit, so don't include it in your estimate.
What is an inflation guard?
It's a feature that automatically raises your dwelling limit by a set percentage at renewal. It may not keep up with local construction cost changes, so still review your limit.
How often should I review my limits?
At least once a year, at renewal, and after any renovation, addition or major purchase.
Who can tell me exactly how much I need?
CoverMoose can't give personal advice. A licensed agent, your insurer or a professional estimator can review your specific home, and your state insurance department can answer questions about local rules.
