What Homeowners Insurance Does Not Cover (2026)

Homeowners insurance covers sudden, accidental events like fires, windstorms, and lightning strikes, but it is not a maintenance plan and it excludes far more than most owners realize. A standard HO-3 policy leaves 13 categories of damage completely unprotected, from floods and earthquakes to termite rot, sewer backups, and jewelry beyond standard dollar caps. Knowing these gaps before a loss occurs determines whether an unexpected bill wipes out years of equity.

These are the 13 categories standard homeowners insurance policy exclusions leave unprotected:

1. Floods. Rising water from storm surge, overflowing rivers, or surface runoff requires a separate NFIP or private flood policy.
2. Earthquakes. Ground movement of any kind, including tremors, requires a standalone earthquake policy or endorsement.
3. Sinkholes and land subsidence. Soil collapse beneath a structure is excluded in most states (Florida is a partial exception).
4. Landslides and mudflows. Earth movement triggered by rain or volcanic activity is excluded.
5. Wear and tear. Gradual degradation of roofing, plumbing, HVAC, and structural components is the homeowner’s responsibility.
6. Maintenance neglect. Preventable damage (burst pipes from failing to heat in winter, a slowly leaking roof) is excluded as the owner’s fault.
7. Pest infestations. Termites, rodents, bed bugs, and bird nesting damage are classified as maintenance failures.
8. Mold from neglect or excluded causes. Mold from a gradual leak or excluded water source is not covered; mold from a sudden covered event may qualify.
9. Sewer and drain backups, including sump pump failures. Coverage requires an optional endorsement, typically $50 to $250 per year.
10. Jewelry, art, and high-value collectibles beyond standard limits. Standard caps: jewelry at $1,500, silverware at $2,500. A floater or scheduled endorsement covers full appraised value.
11. Home-based business property. Standard policies cap business equipment at $2,500 or less. A business owner’s policy is required for full coverage.
12. Home-based business liability. Business-related injuries and lawsuits on the property are excluded from standard personal liability coverage.
13. Intentional damage, war, and nuclear hazards. Damage you deliberately cause or events involving nuclear or war perils are universally excluded.

This guide covers what homeowners insurance exclusions mean and how to find them in your policy, each exclusion category in detail with verified dollar figures, what your policy surprisingly does cover, and a comparison table of optional endorsements with annual cost ranges so you can make a real budget decision.

What homeowners insurance does not cover

Understanding what does homeowners insurance not cover starts with understanding what an exclusion is and where it lives in your policy. The 13-item list above names the perils, but the underlying policy structure determines how broadly or narrowly those exclusions apply to your situation.

What is a homeowners insurance exclusion?

A homeowners insurance exclusion is a peril or cause of loss that your policy explicitly refuses to pay for, even when the resulting damage is severe. Covered perils are the opposite: events the policy agrees to pay for when they cause sudden, accidental damage.

The most common residential policy in the U.S. is the HO-3 policy, per the Insurance Information Institute. The HO-3 covers your dwelling on an open-perils basis, meaning your home’s structure is protected for everything except what the policy specifically excludes. Your personal property coverage, however, operates on a named-perils basis, meaning the policy only pays for personal belongings damaged by specific events listed in the policy. That distinction matters: an event that triggers dwelling coverage may still exclude the same damage to furniture inside if it isn’t listed as a named peril. Older policy forms, HO-1 and HO-2, cover both dwelling and personal property on a named-perils basis, which gives you less protection than a standard HO-3.

Buying a home means arranging homeowners insurance before or at closing. If you’re early in that process, the house closing steps guide walks through exactly when your insurer gets involved and what lenders require.

Specific vs. broad exclusions in your policy

Exclusions fall into two types. Specific exclusions name a single peril (flood, earthquake, wear and tear). Broad exclusions use general language to capture a class of loss (earth movement, external water damage).

To find them, start with your policy declarations page, the one- or two-page summary listing your coverage limits and endorsements. Behind it is the full policy jacket, where Section I covers property exclusions and Section II covers liability exclusions. Look for the heading “Perils Insured Against” and then “Exclusions” in each section. If you can’t locate your policy, your state’s Department of Insurance website lists the minimum disclosure requirements that apply in your market.

A coverage gap exists any time a real risk you face is not addressed by your current policy. The sections below identify each major gap, explain how it works in practice, and show what it actually costs to close it.

Flood damage and sewer backup exclusions

Flood damage is the most common and most costly homeowners insurance exclusion in the country. One in four flood insurance claims comes from properties outside high-risk flood zones, according to FEMA, which means a low-risk zone designation is not the same as no risk.

Flood damage from outside your home

Flooding means water entering your home from an external source: storm surge, river overflow, surface runoff, or water that backs up because a storm overwhelmed municipal drains. Every standard HO-3 policy excludes this peril regardless of cause or severity. Even one inch of standing water can cause $25,000 or more in damage to flooring, drywall, and personal property.

The National Flood Insurance Program (NFIP), administered by FEMA, offers flood insurance to any homeowner regardless of their flood zone designation. The national average NFIP premium runs approximately $700 to $1,000 per year, though that figure can be substantially higher in coastal or high-risk zones. Private flood insurers may offer broader coverage or lower premiums in some markets, and coverage terms vary widely. Only about 27% of U.S. homes with mortgages in high-risk flood zones carry flood insurance, per FEMA. For homes outside those zones, the share is far lower.

Sewer and drain backups

Sewer backup is distinct from external flooding and is excluded separately. Water that enters through a floor drain, a failed sewer line, or a backed-up municipal system falls into this category. It is not covered under the flood exclusion language, and it is not covered under the base policy either. A sewer backup endorsement costs approximately $50 to $250 per year and is among the least expensive homeowners insurance add-ons available.

Sump pump overflow

A failed sump pump that allows water to pool in a basement is also excluded under the base policy. Coverage for sump pump failure is available through the same sewer backup endorsement most carriers offer, not as a separate rider.

What about sudden internal water damage?

The line between covered and excluded water damage runs along “sudden and accidental” versus “gradual or excluded-source.” A pipe that freezes overnight and bursts is a covered event in most states. Water entering through a backed-up drain is excluded. Water that seeped slowly from a supply line for months is excluded as maintenance neglect. If you’re unsure which category an event falls into, document the damage immediately and report it to your insurer before making repairs.

Earthquakes and earth movement

No standard homeowners insurance policy in any of the 50 states covers earthquake damage. Ground movement of any kind, from a minor tremor to a major fault-line event, is excluded under the earth-movement exclusion. Uninsured earthquake damage can eliminate home equity in hours. If you want to understand what’s at stake financially, calculate your home equity before pricing out earthquake coverage so you know what you’re protecting.

Earthquake coverage exclusion

All 50 states exclude earthquake from the standard HO-3 form. California homeowners can purchase a separate policy through the California Earthquake Authority (CEA), which insures approximately 1 million California policyholders. Outside California, earthquake coverage is available as a standalone policy or an endorsement through private insurers. The USGS Earthquake Hazards Program estimates that 42 U.S. states face moderate-to-very-high seismic hazard, meaning this exclusion is relevant far beyond the West Coast.

Sinkholes and landslides

Sinkhole coverage (soil collapse beneath a structure) is mandated in Florida and Tennessee, where geology makes it a common risk. In all other states, sinkhole damage is excluded by default. Landslide and mudflow coverage is excluded nationally; some specialty insurers offer it as a separate policy for homes on sloped terrain. Neither peril is addressed by a standard endorsement to an HO-3.

What earthquake insurance costs

Earthquake insurance typically runs $800 to $5,000 or more per year depending on your seismic zone, the age of your home, and your dwelling’s replacement cost value, per Insurance Information Institute data. Homes built before modern seismic codes and homes on soft soils pay significantly more. In lower-risk zones, earthquake endorsements may be available for $200 to $400 per year through some private carriers.

Wear and tear and maintenance neglect

Wear and tear is the second most common reason insurers deny homeowner claims, after excluded perils like floods and earthquakes. The Texas Department of Insurance guidance on maintenance exclusions identifies deferred maintenance as one of the top five sources of coverage disputes in the state, a pattern that holds across most state DOI annual complaint data.

The core principle: gradual damage from maintenance neglect is never a covered peril. The question every adjuster asks is whether an event was sudden and accidental, or whether damage accumulated because you failed to act. That distinction alone determines whether your claim is approved.

A home inspector identifies many of the same deterioration conditions that insurers later exclude from claims. Understanding what home inspectors can’t report helps clarify which defects fall in the coverage gap and which don’t.

What counts as normal wear and tear

Normal wear and tear is gradual, expected degradation that comes from age and use. Aging roof shingles that lose granules over time, a water heater past its rated lifespan, crumbling caulk and sealant around windows, and a gradually sagging subfloor are all examples. Your policy will not pay to replace or repair any of them, regardless of how significant the resulting damage becomes.

When neglect voids otherwise covered damage

Some damage begins with a covered peril but becomes excluded once neglect enters the picture. A small roof breach after a windstorm is a covered event. If you know about it and fail to act for several months, the resulting water intrusion and structural damage may be reclassified as maintenance neglect. Similarly, a plumbing leak that drips slowly behind a wall for six months, causing mold and structural rot, is classified as gradual damage rather than a sudden accidental event. Insurers may request repair records to establish whether you took reasonable steps after discovering a problem.

Roof age and coverage limitations

Many insurers limit payouts on roofs older than 20 years to actual cash value (the depreciated value) rather than replacement cost value. Some carriers refuse to renew policies on very old roofs altogether. If your roof is approaching the 20-year mark, get a professional inspection and document current conditions. That record can be critical for establishing the timeline of any future damage claim.

Pest infestations and animal damage

Pest damage is excluded from every standard homeowners insurance policy because infestations are classified as maintenance failures, not sudden accidental events. The reasoning: an infestation develops over time, and an attentive homeowner has repeated opportunities to detect and address it before significant structural damage occurs.

Termite damage

Termites represent the most expensive single pest exclusion. The National Pest Management Association (NPMA) estimates termites cause $5 billion in U.S. property damage annually, none of which is typically covered by a standard policy. Structural damage from termite colonies can progress for years before becoming visible, often reaching floor joists, support beams, and framing before a homeowner notices.

A termite bond or annual pest control contract is the standard protection. Many real estate transactions require a wood-destroying organism (WDO) inspection before closing. If that inspection wasn’t required on your purchase, scheduling one now costs $75 to $150 and can catch an active colony before it becomes a $20,000 repair.

Rodents, birds, and bed bugs

Mice, rats, squirrels nesting in attic spaces, and birds nesting in soffits all fall under the pest exclusion. Damage they cause, including chewed wiring, gnawed insulation, and structural contamination, is excluded as a maintenance failure. Bed bug infestation damage is excluded by all standard HO-3 policies, including damage to furniture and the full cost of remediation.

Wildlife exceptions

A key nuance: sudden, visible animal damage may be covered under a standard policy’s open-perils dwelling coverage. If a bear breaks through a wall or a deer crashes through a glass door, that single event is sudden and accidental, and the resulting repair may qualify under your dwelling coverage. Gradual nesting damage from squirrels chewing through soffit material over a full season is not covered. Review your policy’s “sudden and accidental” language to determine which side of the line a specific event falls on.

Mold and gradual water damage

Mold coverage is one of the most misunderstood areas in home insurance exclusions. Whether a mold claim is covered or excluded depends entirely on the underlying cause of the moisture, not on the mold itself.

When mold IS covered

Mold that results directly from a sudden covered event may be included in that original claim. If a burst pipe floods your bathroom and mold begins growing within days, the remediation may be covered as part of the burst-pipe claim. Document the water damage and call your insurer immediately. Delayed reporting can give the insurer grounds to reclassify the mold as gradual damage.

Per EPA mold resources for homeowners, mold begins to grow within 24 to 48 hours of water exposure, so quick action after any water event matters for both health and coverage purposes.

When mold is NOT covered

Mold is excluded when it results from a gradual leak you failed to repair, from humidity and condensation buildup due to poor ventilation, or from flooding (which is itself an excluded peril). Even a small slow drip behind a cabinet may be classified as maintenance neglect if the insurer determines the source was detectable with reasonable attention.

Mold remediation costs average $1,500 to $3,150 for standard cases and can exceed $10,000 for severe infestations, per industry estimates. These costs fall entirely on the homeowner when the cause is excluded. The standard homeowners insurance policy exclusions for mold are some of the most consequential in the policy for homeowners in humid climates.

Mold endorsements

Some states permit insurers to offer a mold endorsement. Where available, annual premiums typically range from $500 to $2,000, depending on the carrier and the home’s characteristics. Check your state’s Department of Insurance website to confirm whether this option is available in your market before assuming it doesn’t exist.

High-value items, business, and intentional damage

Standard personal property coverage under an HO-3 policy sets hard dollar caps on specific categories of belongings. Most homeowners discover these caps only after a loss. For investors running a rental or home-based operation, the business exclusions create an additional coverage gap that a separate policy is required to close. This gap is one reason real estate investing risks and rewards include a look at insurance obligations that catch new investors off guard.

Standard caps on jewelry and collectibles

Your policy’s personal property coverage likely caps:

• Jewelry at $1,500 per occurrence
• Silverware and goldware at $2,500
• Firearms at $2,500
• Fine art: typically $0 to $500 without a floater

These caps apply even if a thief steals a $20,000 engagement ring or fire destroys a $15,000 coin collection. Musical instruments, cameras, and specialty electronics may also carry sub-limits that aren’t obvious from the declarations page and that many homeowners discover only after a loss.

Scheduled personal property floaters

A scheduled personal property floater (also called a personal articles floater or endorsement) lists each item individually at its appraised value. Annual cost is approximately 1% to 2% of the item’s appraised value, per Insurance Information Institute data. A $10,000 engagement ring, for example, would cost roughly $100 to $200 per year to insure at full value. Most floaters also cover accidental loss and mysterious disappearance, perils that standard policies exclude entirely for jewelry and collectibles.

Home-based business exclusions

Standard HO-3 policies cap business property (computers, inventory, professional equipment used for commercial purposes) at $2,500 or less. Business liability, including a client injured during a home visit or a product liability claim arising from goods you manufacture at home, is excluded from personal homeowners liability coverage. A business owner’s policy (BOP) covers both business property and business-related liability. In-home business endorsements, a less comprehensive option, are available from most carriers for $100 to $500 per year if your business activity is limited in scope.

Intentional damage and criminal acts

Damage you deliberately cause to your own property is excluded from every standard policy. Damage arising from illegal activities conducted on the property can result in full policy voiding under most state laws, not just a claim denial for that specific event. Coverage outcomes for intentional acts and criminal activity vary by state. The Arizona Department of Insurance homeowners coverage guidance offers a state-level reference for how these scenarios are handled, and your state’s equivalent site provides local rules.

What homeowners insurance surprisingly covers

Not every gap runs in the direction most homeowners expect. Several covered perils under a standard HO-3 surprise people who assume they’d need a separate policy. These inclusions address the inverse query that all four major AI engines return as a separate result: what does standard coverage protect?

Falling objects, including space debris

Falling objects are a named peril in most standard HO-3 open-perils policies, per the Insurance Information Institute. This includes meteors, satellites, and aircraft components that fall from the sky. If a piece of space hardware crashes through your roof, your dwelling coverage likely responds. The key condition: the damage must be sudden and accidental. A tree branch that falls gradually from rot is a maintenance issue, not a covered falling object.

Dog bites off your property

The liability portion of a standard HO-3 policy typically extends to dog bite incidents that occur away from your home, not just on your property. If your dog bites someone at a park, your homeowners liability coverage may cover the resulting medical expenses and legal costs up to your liability limit, usually $100,000 to $300,000. Some breeds are excluded by specific carriers; check your policy’s animal exclusion language before assuming coverage applies.

College students’ belongings in dorms

If you have a dependent child living in a college dormitory, their personal belongings are typically covered under your homeowners policy up to 10% of your personal property coverage limit. If you carry $100,000 in personal property coverage, your student’s laptop, clothing, and furniture in the dorm are covered up to $10,000. Off-campus apartments are less commonly covered; confirm with your insurer before your student moves in.

Spoiled food after a power outage

Food spoilage caused by a power outage triggered by a covered peril (a windstorm that takes down local power lines, for example) is covered under many standard policies, typically up to $500. This is often included in the “additional coverages” section of the policy jacket, not as a separate endorsement. It applies when the outage cause is a covered peril, not when the outage is due to a grid failure unrelated to a covered event.

Identity theft (some policies)

Newer homeowners insurance policies increasingly include limited identity theft resolution coverage as a named endorsement or included benefit. Coverage typically assists with costs related to restoring your credit and identity, not with direct financial losses from fraud. If this matters to you, ask your insurer whether it’s included or available as an optional add-on when you next review your homeowners insurance add-ons.

How to add coverage for excluded perils

Understanding what does homeowners insurance not cover is only useful if it leads to action. Each major home insurance exclusion has a corresponding coverage option. What varies is the cost, the provider, and how quickly you need to act before a disaster happens.

How to read your policy’s exclusions section

Your policy declarations page summarizes what you have: coverage limits, named endorsements, and the policy form number. The full exclusion language lives in the policy jacket behind it. Section I covers property damage exclusions; Section II covers liability exclusions. Under each section, look for “Perils Insured Against” followed by “Exclusions.”

For the dwelling (the physical structure of your home), coverage under an HO-3 is open perils: everything is covered unless specifically excluded. For personal property, coverage is named perils: only specific events listed in the policy are covered. A peril that isn’t listed for personal property is automatically excluded, even if the same damage to the structure would be covered.

The CFPB homeowners insurance resources page explains what disclosures lenders require around insurance coverage, which is useful context if you’re interpreting what your mortgage servicer requires at closing or renewal.

When a separate standalone policy is better than an

For flood and earthquake, a standalone policy is almost always the better path.

For flood: endorsements from private insurers for flood coverage are rare and often more expensive per dollar of protection than a standard NFIP policy. NFIP flood insurance covers up to $250,000 in dwelling damage and $100,000 in personal property. Private flood insurance may offer higher limits or broader terms in some markets. There is typically a 30-day waiting period for new NFIP policies before coverage takes effect.

For earthquake: in California, the California Earthquake Authority typically provides more comprehensive coverage than private endorsements. In other seismic states, a standalone policy usually delivers higher limits and broader structural protection than a simple add-on.

For sewer backup, jewelry, and home business property, an endorsement to your existing policy is usually faster, cheaper, and administratively simpler than a separate standalone policy.

Homeowners Insurance Exclusions in Your State

Home insurance exclusions vary by state. Sinkhole coverage mandates (Florida, Tennessee), mold endorsement availability, and attorney-required closing procedures all differ depending on where you live. Until state-specific exclusion guides are available on this site, your best starting point is your state’s Department of Insurance website. A search for “[your state] Department of Insurance homeowners insurance” takes you directly to the state’s disclosure requirements, licensed carrier lists, and consumer complaint resources.

If your home has damage that standard homeowners insurance policy exclusions leave unprotected (termite rot, deferred maintenance, flood-damaged drywall, or persistent mold), a traditional sale can stall quickly. Financed buyers rely on appraisals and inspection contingencies, and a discovered defect can unravel a deal at the last minute. Through iBuyer.com, cash buyers purchase properties as-is: no repairs required, no contingency risk, and experienced buyers who understand disclosed conditions. Get competing cash offers within 24 hours and compare before you commit. Closing typically takes 7 to 30 days on a timeline you control.
