Rising construction costs and natural disasters have left millions of homeowners underinsured. Learn how to check your coverage and avoid costly gaps.
Introduction — the risk of being underinsured in 2025
A shocking number of homeowners don’t have enough insurance to rebuild their homes after a disaster. According to Kin Insurance, about 18% of American homeowners admit their policy wouldn’t fully cover a rebuild, and rising construction costs mean 42 million homes are underinsured in 2025.
Being underinsured means your policy’s coverage limit is less than the actual replacement cost of your home. If a fire, storm, or earthquake strikes, you could face tens or hundreds of thousands in uncovered costs.
What does it mean to be underinsured?
You’re underinsured if your homeowners insurance coverage wouldn’t fully pay to:
Cover temporary living expenses while repairs happen.
Rebuild your home at today’s construction costs.
Replace your personal belongings.
Example:
- Home replacement cost: $400,000.
- Insurance dwelling coverage: $300,000.
- Shortfall if destroyed: $100,000 (you pay out-of-pocket).
This guide shows you how to perform a homeowners insurance checkup, identify common coverage gaps, and adjust your policy to avoid a financial shortfall.
Why underinsurance is growing in 2025
- Rising construction costs — lumber, labor, and materials surged after the pandemic and inflation hasn’t fully eased.
- Natural disasters increasing — hurricanes, wildfires, and floods are hitting more regions.
- Home upgrades not reported — remodeling kitchens, bathrooms, or adding rooms without updating insurance.
- Policy limits outdated — some people set coverage years ago and never adjusted for inflation.
Homeowners Insurance Checkup — how to evaluate your coverage
1. Calculate your home’s replacement cost
- Ask your insurer for a replacement cost estimate (not market value).
- Factor in today’s building material and labor costs.
- Use tools like cost estimators from Insurance Information Institute (III.org).
2. Check your dwelling coverage (Coverage A)
- Make sure it matches replacement cost.
- Add an inflation guard endorsement if possible — automatically adjusts coverage as costs rise.
3. Review personal property coverage (Coverage C)
- Standard = 50–70% of dwelling coverage.
- Consider a home inventory to see if limits are enough.
- Add riders for high-value items (jewelry, art, electronics).
4. Look at additional living expenses (ALE)
- Covers hotel, food, rentals while displaced.
- Check if your limit is realistic for 6–12 months in your city.
5. Review liability coverage (Coverage E)
- Covers lawsuits if someone is injured on your property.
- Experts recommend $300,000–$500,000 minimum in 2025.
Common coverage gaps
- Floods: Not covered under standard policies. Requires NFIP or private flood insurance.
- Earthquakes: Excluded; need separate earthquake insurance.
- Hurricanes/windstorms: Coastal policies may exclude wind; separate riders required.
- Sewer backup: Optional add-on in most states.
- Inflation gaps: Without inflation riders, coverage falls behind actual costs.
- High-value possessions: Jewelry, art, collectibles often need separate riders.
How to avoid being underinsured
- Update coverage annually — recalculate replacement cost.
- Add inflation guard endorsements — automatically increases limits.
- Insure to value — always match replacement cost, not market value.
- Review after renovations — report upgrades like new kitchens or additions.
- Consider extended replacement cost coverage — adds 10–50% above dwelling coverage in case costs surge.
- Buy separate disaster insurance if in flood, earthquake, or wildfire zones.
- Re-check deductible options — higher deductibles lower premiums but require emergency savings.
