What Homeowners Insurance Does NOT Cover

Understanding what homeowners insurance does not cover matters more than knowing what it does — because coverage gaps tend to surface only after a claim gets denied. A standard HO-3 policy handles fire, wind, theft, and most sudden accidents, but it walks past several major risks that homeowners assume are automatic. This guide breaks down the exclusions that catch people off guard most often, plus the endorsements that can plug the biggest holes.

The Standard Policy: Named Perils vs. Open Perils

Most US homeowners carry an HO-3 policy, which covers the dwelling on an open perils basis (anything not specifically excluded) and personal property on a named perils basis (only the causes listed). That distinction matters. When people ask what homeowners insurance does not cover, the answer starts with the standard exclusion list found in nearly every carrier's policy: flood, earthquake, war, nuclear hazard, government seizure, ordinance or law, and neglect. Some carriers add mold, sewer backup, and power failure to that same list.

Premiums vary wildly by state — from around $1,000 per year in Vermont or Idaho to well over $5,000 per year in coastal Florida and Louisiana — but the exclusion language reads almost identically across carriers. The differences show up in what riders and endorsements each insurer will bolt onto the base policy, and at what price.

Flood Damage Is Almost Never Covered

Water damage is the coverage question that trips up the most homeowners. A pipe that bursts and floods the kitchen? Covered. Water rising up through the foundation because a nearby creek overflowed? Not covered. That's flood, and flood is specifically excluded from every standard homeowners policy in the United States.

Flood coverage comes through the National Flood Insurance Program (NFIP) or a small handful of private flood insurers. NFIP policies max out at $250,000 for the dwelling and $100,000 for contents, with premiums that typically run $500-$2,000 per year depending on the flood zone. Homes inside a Special Flood Hazard Area with a federally-backed mortgage are required to carry it. Homes outside those zones can still buy it — and often should. A meaningful share of NFIP claims each year come from properties FEMA mapped as low or moderate risk, especially after flash-flood events in inland states like Tennessee, Vermont, and Kentucky.

Earthquake, Sinkholes, and Ground Movement

Earthquakes get excluded across the board, and so does the broader category of earth movement — which sweeps in landslides, mudslides, sinkholes, and soil settling. That's a bigger deal than it sounds. A California homeowner without earthquake coverage pays out of pocket for a cracked foundation from seismic shifting. So does a Florida homeowner whose lot develops a sinkhole (Florida requires carriers to offer sinkhole coverage, but it's an add-on with a hefty deductible).

Earthquake endorsements and standalone policies typically cost $100-$800 per year outside high-risk regions and $800-$3,000 or more per year in California. Deductibles are almost always percentage-based — 10% to 25% of the dwelling coverage. On a $400,000 home, that's a $40,000-$100,000 deductible before coverage kicks in, which is why many homeowners in seismic zones self-insure the smaller claims and buy earthquake purely for a catastrophic-loss scenario.

Sewer Backups and Sump Pump Failures

Water that backs up through a floor drain, toilet, or basement sink is called a sewer or drain backup, and standard policies exclude it. So does sump pump failure — the situation where a groundwater pump gives out during a heavy rain and the basement floods from below.

Both get added back through a water backup endorsement, usually $50-$250 per year for $5,000-$25,000 in coverage. Homes with finished basements or below-grade living space almost always benefit from carrying it, especially in older neighborhoods where the municipal sewer main can surge during storms and push wastewater backward through the house's plumbing. A modest endorsement here is one of the highest-value dollars a homeowner spends.

The 12 Exclusions Most Homeowners Assume Are Covered

Beyond the big three (flood, earthquake, sewer backup), a standard HO-3 policy also walks past a dozen more common losses. Understanding what homeowners insurance does not cover across the full list is the difference between a smooth claim and a five-figure surprise:

1. Flood damage from rising groundwater or storm surge
2. Earthquake, sinkhole, and landslide damage
3. Sewer or drain backups (without endorsement)
4. Termite, carpenter ant, rodent, and other pest damage
5. Mold, unless it stems from a covered water loss
6. Wear and tear, rot, and gradual deterioration
7. Foundation cracks from settling or expansive soil
8. Roof leaks caused by age or deferred maintenance
9. Home-business inventory and equipment above small sublimits
10. High-value jewelry, art, and collectibles over the schedule limit (typically $1,500-$2,500)
11. Damage from war, nuclear events, or government seizure
12. Intentional damage caused by the policyholder or a resident

Maintenance and Wear-and-Tear Won't Be Reimbursed

The single most common denied-claim category is maintenance-related. Insurers pay for sudden and accidental damage, not for the slow-motion consequences of a home falling behind on upkeep. Common denials include:

• Roof shingles that gradually deteriorated and started leaking during a routine storm
• Pipe corrosion or pinhole leaks that developed over years
• HVAC systems that failed from age or lack of servicing
• Deck rot, siding wear, and foundation settling
• Pest infestations — termites, carpenter ants, rodents, bats
• Mold from a chronically damp bathroom, attic, or crawlspace

Adjusters look hard at the age and condition of building components. A 25-year-old roof damaged by hail may be paid on an actual cash value basis (depreciated) even if the overall policy is replacement cost. Timestamped photos, service receipts, and a basic maintenance log go a long way toward keeping a legitimate claim from getting recategorized as neglect.

Endorsements That Fill the Biggest Gaps

Most of these exclusions can be bought back — either as an add-on rider to the main policy or as a standalone product. The economics almost always favor the coverage, since the annual cost is a small fraction of the potential loss.

Endorsement or Policy	Typical Annual Cost	Common Coverage Amounts
Water backup	$50-$250	$5,000-$25,000
Flood (NFIP)	$500-$2,000	Up to $250K dwelling / $100K contents
Earthquake	$100-$3,000+	Dwelling limit, 10-25% deductible
Scheduled personal property	$10-$30 per $1,000 insured	Per-item, no deductible
Service line	$30-$75	$10,000 typical
Equipment breakdown	$25-$50	$50,000-$100,000 typical
Ordinance or law	$25-$100	10-25% of dwelling coverage

Ordinance or law is one of the most under-discussed lines. When an older home suffers a major loss and gets rebuilt, current building code often requires upgrades — new electrical, plumbing, structural, or ADA-related work. A standard policy only pays to rebuild as-was; the ordinance endorsement covers the code-required upgrades.

What to Ask Before a Claim, Not After

Reading the declarations page once a year is the cheap version of due diligence. The dwelling limit should reflect current rebuild cost, which has moved 30-40% higher across many US metros since 2020. Personal property coverage should exceed the value of what's actually in the house, especially electronics and jewelry. Loss of use — also called Additional Living Expense — should cover 6-12 months of comparable housing if the home becomes uninhabitable.

A few concrete steps expose problems before they become claim denials:

• Do a slow video walkthrough of the interior once a year and store it in cloud backup
• Photograph the roof, gutters, and foundation after each season
• Confirm any high-value items — rings, watches, firearms, art — are individually scheduled on the policy
• Ask the carrier for the full policy jacket showing the complete exclusion list, not just the declarations page

That last step matters more than most homeowners realize. Declarations summarize coverages and dollar limits but rarely list exclusions. The full policy — often 30-50 pages — is where the actual language lives, and where a $30,000 gap tends to hide in a single sentence.

Frequently Asked Questions

Does homeowners insurance cover water damage?

It depends entirely on the source. Sudden and accidental water damage from a burst pipe, appliance overflow, or roof leak from a covered peril is generally covered. Water from outside the home — flood, storm surge, groundwater seepage — and water that backs up through drains or sump pumps is excluded from a standard policy and requires separate coverage.

Is mold covered by homeowners insurance?

Mold is only covered when it results from a covered water loss, like a burst pipe that wasn't discovered for a few days. Mold caused by chronic humidity, a slow shower leak, or long-term seepage is treated as a maintenance issue and denied. Even when covered, many carriers cap mold remediation between $5,000 and $10,000.

Does homeowners insurance cover foundation problems?

Foundation damage from a sudden covered event — a vehicle striking the house, a fire, an explosion — is covered. Cracks from settling, expansive soil, poor drainage, tree roots, or gradual shifting are excluded as earth movement or wear and tear. Sinkhole damage is a separate endorsement, and states like Florida and Tennessee require carriers to at least offer it.

Are termites covered by homeowners insurance?

No. Termite damage — along with damage from rodents, carpenter ants, powderpost beetles, and other pests — is universally excluded from standard policies. Insurers view pest damage as preventable through routine maintenance and pest control, and even sudden structural collapses caused by termite-weakened framing are almost always denied.

What is the difference between HO-3 and HO-5 coverage?

An HO-3 policy is the most common form: open perils on the dwelling, named perils on personal property. An HO-5 upgrades both the dwelling and personal property to open perils, which shifts the burden of proof to the insurer to show a loss is excluded. HO-5 typically costs 10-15% more but pays out on more claims involving personal belongings.
