What Home Insurance Doesn't Cover: 15 Common Exclusions You Need to Know

The Big Picture: Why Home Insurance Has Exclusions

Home insurance is designed to protect you from sudden and accidental losses, not from every possible risk under the sun. Insurers carve out exclusions for three primary reasons:

1. Catastrophic or uninsurable risk. Events like floods or wars could trigger simultaneous massive claims that would bankrupt an insurer.
2. Preventable or gradual damage. Wear and tear, neglect, and pest infestations are considered a homeowner's responsibility to manage.
3. High moral hazard. Intentional acts or business activities create incentives for fraud.

Understanding why exclusions exist helps you recognize which ones you can address with add-ons and which ones require a separate policy entirely. As the 2026 market has tightened, insurers have narrowed wording around water damage, mold, and maintenance-related losses, shifting more risks into endorsements, sublimits, or separate policies. J.D. Power's 2025 Property Claims Satisfaction Study found homeowner satisfaction has dropped sharply, with average claim cycle times now stretching to 44 days as insurers apply exclusions more aggressively.

The 15 Most Common Home Insurance Exclusions

1. Flood Damage

Standard homeowners policies do not cover flooding, including storm surge, overflowing rivers, heavy rain runoff, or flash floods. This is the single biggest coverage gap that catches homeowners off guard.

Why it's excluded: Floods are widespread events that affect thousands of homes simultaneously, creating catastrophic claims that standard insurers can't absorb.

Alternative: Purchase a separate flood insurance policy through the National Flood Insurance Program (NFIP) or a private insurer. According to NerdWallet's 2026 NFIP analysis, the national average NFIP policy now costs about $976 per year (roughly $81/month). High-risk zones (A or V) average $1,114/year, low-to-moderate risk zones average $745/year, and private/coastal policies can exceed $2,800/year. Under FEMA's Risk Rating 2.0, annual premium increases remain capped at 18%. Note that NFIP's authorization lapsed on September 30, 2025, so new/renewal NFIP policies depend on Congressional reauthorization, while private flood insurers have expanded to fill the gap. Get the full breakdown in our flood insurance cost and coverage guide.

2. Earthquake Damage

Earthquake damage, including cracked foundations, collapsed walls, and broken pipes caused by seismic activity, is excluded from every standard home policy.

Why it's excluded: A single major earthquake can destroy thousands of homes simultaneously, creating liability that no single insurer could manage.

Alternative: Add an earthquake endorsement or purchase a standalone earthquake policy. Annual costs range from around $250 on the East Coast (about $0.50 per $1,000 of coverage) to $1,250 to $2,750 in California, where the state average runs about $3.54 per $1,000 of coverage (roughly $2,478 for a $700,000 home). Higher-risk cities like Alameda average $6.50 per $1,000 (about $4,550/year on a $700,000 home), while inland areas like Sacramento are much cheaper. The California Earthquake Authority also approved a 6.8% rate increase heading into 2026, so shop around and consider retrofit discounts of up to 25%.

3. Land Movement (Sinkholes, Mudslides, Landslides, Subsidence)

Even if an earthquake didn't cause it, any movement of the ground beneath your home, including sinkholes, mudslides, soil settling, and land subsidence, is typically excluded.

Why it's excluded: These are location-specific, highly predictable geological risks. Insurers view them similarly to flood risk.

Alternative: Earthquake policies often include some earth movement coverage. In Florida and Tennessee, insurers must offer optional sinkhole coverage, which is critical given Florida has the highest incidence of sinkholes in the US.

4. Sewer Backup & Sump Pump Failure

Water that backs up through a drain, sewer line, or a failed sump pump is not covered under a standard policy, even though it can cause tens of thousands of dollars in basement damage. Understand more in our full breakdown of water damage coverage gaps and basement flooding scenarios.

Why it's excluded: Sewer backup results from either infrastructure failures or maintenance neglect, neither of which is considered a sudden, accidental peril.

Alternative: A water backup endorsement typically costs $50 to $250 per year, with basic $5,000 coverage available for as little as $30 to $70 annually. Coverage limits usually range from $5,000 to $25,000 per occurrence, with average claims running $3,000 to $15,000 (severe cases can exceed $50,000). For finished basements with home offices or rec rooms, most agents recommend a minimum of $15,000 in backup coverage.

5. Wear & Tear / Deterioration

If your roof slowly deteriorates over 20 years and eventually leaks, your insurer won't pay. Neither will they cover aging pipes, crumbling foundations, or worn-out HVAC systems. About 70% of carriers now enforce a 20-year roof age threshold, and many carriers have tightened rules further to require actual cash value (ACV) settlement on roofs older than 10 to 15 years.

Why it's excluded: Gradual deterioration is a maintenance issue, not an insurable peril. Policies cover sudden damage, not inevitable aging.

Alternative: There's no insurance for wear and tear. A home warranty can cover repair or replacement of major systems and appliances due to age. Learn how maintenance requirements affect your claims in the current market.

6. Neglect & Failure to Maintain

If a small roof leak goes unaddressed for months and causes structural rot, the insurer can deny the entire claim, even for the portion that might otherwise have been covered. Insurers now use drones, satellite imagery, and AI to assess property condition. A 2026 Weiss Ratings analysis found that 15 large US insurers denied at least 50% of homeowner and farmowner claims in 2025, with Mid-Century Insurance of Texas closing 78% of claims with no payment, Lemonade at 64%, and Citizens Property Insurance (FL) and Farmers Insurance Exchange each above 55%.

Why it's excluded: Homeowners have a legal duty to mitigate damage. Ignoring known problems is considered negligence, not a covered peril.

Alternative: Keep a maintenance log, schedule annual inspections, and document all repairs with dated photos. If your claim is denied, review our guide on what to do after a home insurance denial.

7. Mold from Chronic Moisture

Mold caused by long-term humidity, leaking pipes that went unaddressed, or poor ventilation is generally not covered unless it results directly from a sudden covered event (like a burst pipe). Most policies now exclude mold entirely or cap coverage at around $10,000.

Why it's excluded: Insurers consider chronic mold a maintenance failure. In recent years, policies have tightened mold language significantly to reduce claims abuse.

Alternative: A limited mold endorsement can add some remediation coverage, and water backup endorsements often include minor mold cleanup when the mold is directly caused by a covered backup. The best defense, however, is moisture control. Use dehumidifiers, fix leaks immediately, and ensure proper ventilation.

8. Pest Infestations

Termites, rodents, cockroaches, bed bugs, none of these are covered by a standard home policy, even if they cause structural damage.

Why it's excluded: Pest infestations are considered gradual and preventable with proper maintenance and routine inspections.

Alternative: Regular pest control contracts, annual termite inspections, and a home warranty that includes pest treatment are your best options.

9. Certain Dog Breeds

Your homeowners policy includes personal liability coverage if your dog bites someone. But if you own a breed on the insurer's exclusion list, that bite claim may be denied entirely. Pit bulls, Rottweilers, and Doberman pinschers appear on nearly every insurer's banned list, and the average dog bite claim now exceeds $65,000.

Commonly excluded breeds include:

Why it's excluded: These breeds are statistically associated with higher dog bite claims and more severe injuries, creating elevated liability risk.

Alternative: Seek out breed-blind insurers. State Farm, USAA, Nationwide, Amica, Chubb, Liberty Mutual, and Fireman's Fund do not use breed lists and instead evaluate individual bite history. Michigan and Pennsylvania have passed laws prohibiting insurers from denying or canceling coverage solely based on dog breed, and Michigan lawmakers reintroduced expanded legislation in February 2026 that would also prohibit insurers from even asking about breed. Get the full playbook in our dog breeds and home insurance guide. You can also add a personal umbrella policy for broader liability protection.

10. Business Liability & Property

If you run a business from home, even a part-time Etsy shop, daycare, or consulting practice, your standard policy typically limits business property coverage to around $2,500 and provides zero liability coverage for business-related activities.

Why it's excluded: Business risks are commercially underwritten and require different actuarial models than personal homeowners coverage.

Alternative: Add a home-based business endorsement or business pursuits endorsement for a few hundred dollars per year. For larger operations, a separate Business Owner's Policy (BOP) is recommended. Our home business insurance coverage guide breaks down each option.

11. Intentional Damage

If you or a household member intentionally damages your own property, or a neighbor's, your insurer will deny the claim.

Why it's excluded: This is a fundamental principle of insurance: coverage is for accidental losses. Covering intentional acts would create enormous moral hazard and invite fraud.

Alternative: There is no insurance for deliberate destruction. This exclusion is absolute.

12. Nuclear Hazard

Damage caused by nuclear radiation, radioactive contamination, or nuclear reaction is excluded from every standard home insurance policy in the US.

Why it's excluded: The potential for catastrophic, widespread liability makes nuclear risk completely uninsurable in the private market.

Alternative: The federal Price-Anderson Nuclear Industries Indemnity Act provides a government-backed compensation system for nuclear incidents, though it is limited and complex.

13. War & Government Action

Damage resulting from declared or undeclared war, military conflict, insurrection, or government seizure of property is universally excluded.

Why it's excluded: These are systemic catastrophic events beyond the scope of private insurance markets.

Alternative: No private alternative exists. Some federal disaster relief programs may provide limited assistance after certain government-declared events.

14. Ordinance or Law (Building Code Upgrades)

If your home is destroyed and local codes now require upgraded wiring, plumbing, or structural standards to rebuild, your standard policy may only pay for like-for-like replacement, not the additional cost to meet new codes.

Why it's excluded: Standard policies are designed to restore your home to its pre-loss condition, not to upgrade it.

Alternative: Add an Ordinance or Law endorsement, which covers the extra cost of bringing your rebuild up to current building codes. This is especially important for older homes, and it also matters for structural damage claims after a major loss.

15. Vacant or Unoccupied Homes

If your home sits vacant for 30 to 60+ days (the threshold varies by policy), your coverage may be significantly reduced or voided entirely for many perils.

Why it's excluded: Vacant homes face higher risks of vandalism, squatters, undetected water leaks, and fire, with no occupant to respond quickly.

Alternative: Purchase a vacant home insurance policy or notify your insurer before extended absences to arrange a vacancy permit. These specialty policies average around $4,200 per year, or 50% to 60% more than standard coverage.

Frequently Asked Questions

Does home insurance cover roof damage from age?

No. If your roof fails due to age, wear, or gradual deterioration, your homeowners policy will not cover it. About 70% of insurers now enforce a 20-year roof age threshold, and many carriers now settle claims on roofs older than 10 to 15 years at actual cash value rather than full replacement cost. Regular roof inspections and timely repairs are the best way to keep your coverage intact and avoid claim denials.

Will home insurance cover mold removal?

It depends on the source of the mold. If mold develops as a direct result of a covered sudden event like a burst pipe, your policy may cover remediation up to its mold sub-limit (typically capped around $10,000). However, mold caused by long-term humidity, gradual leaks, or neglected maintenance is almost always excluded. A mold or water backup endorsement can provide additional protection, but prevention through proper ventilation and moisture control is your best defense.

What happens if my dog bites someone and the breed is excluded?

If your insurer has a breed exclusion and your pet bites a guest, your liability claim can be denied entirely. You would then be personally responsible for medical bills, legal fees, and any judgments against you, which now average over $65,000 per bite claim and can reach six figures. Options include switching to a breed-blind insurer (State Farm, USAA, Nationwide, Amica, Chubb, or Liberty Mutual), adding a personal umbrella policy, or living in a breed-blind state like Michigan or Pennsylvania.

Is flood insurance worth it if I'm not in a high-risk flood zone?

Yes, in many cases. FEMA reports that over 25% of NFIP flood claims come from properties outside high-risk Special Flood Hazard Areas, and premiums in low or moderate risk zones average about $745/year. Given that only about 4% of US households carry flood insurance, and the average NFIP claim payment ran roughly $82,600 from 2020 to 2024, the coverage gap is enormous. Even a few inches of floodwater can cause $25,000+ in damage, making coverage very affordable relative to the risk.

Can I add all these endorsements to any home insurance policy?

Most endorsements like water backup, ordinance or law, and scheduled personal property can be added to standard HO-3 or HO-5 policies through your existing insurer. However, availability and pricing vary by company and state, and some insurers don't offer certain endorsements at all. That's why it's important to compare policies before purchasing. For major gaps like flood and earthquake, you'll need completely separate policies regardless of who your homeowners insurer is.
