What Homeowners Insurance Covers & Excludes (2026 Guide)
A standard homeowners policy — the HO-3 form most US owners carry — covers six things: your house, detached structures, personal belongings, personal liability, medical payments to guests, and living expenses if you're displaced. The single rule that decides most disputes is simple: sudden and accidental damage is generally covered, while gradual damage from wear or neglect is not. That distinction is why a burst pipe is usually paid but a slow leak often isn't — and why, on a $400,000 home, a 5% hurricane deductible can mean $20,000 out of pocket before coverage even begins.
What does homeowners insurance actually cover?
A standard policy covers six parts, and the size of each is anchored to your dwelling limit (Coverage A). Set that number to your rebuild cost and the rest follows automatically.
- Coverage A — Dwelling: the house structure itself.
- Coverage B — Other structures: detached garage, shed, gazebo — generally about 10% of the dwelling limit.
- Coverage C — Personal belongings: generally 50–70% of the dwelling limit, and covered anywhere in the world (some insurers cap off-premises items at 10%).
- Coverage D — Loss of use (ALE): hotel, meals, and lost rent while your home is rebuilt; the limit is separate from your rebuild funds and often carries a time limitation — check your policy for the exact figure.
- Liability: limits typically start around $100,000; raise it with an umbrella policy.
- Medical payments: no-fault coverage for a guest injured on your property.
Watch the small print inside those limits. Standard policies pay up to $500 for unauthorized use of your credit cards, and trees, plants, and shrubs are usually covered at about $500 per item — but not for disease or poor maintenance.
Here's the nuance most guides skip: HO-3 insures the structure on an open-perils basis (everything is covered unless specifically excluded), but your belongings on a named-perils basis — paid only for listed causes like fire, windstorm, hail, theft, vandalism, lightning, falling objects, and the weight of ice or snow.
What's covered vs. not covered — and why?
The decisive test insurers apply is whether the loss was sudden and accidental, not slow and preventable. The table below sorts the common cases.
| Generally covered | Generally excluded |
|---|---|
| Fire, lightning, windstorm, hail | Floods and storm surge (needs NFIP or private flood) |
| Theft, vandalism, falling objects | Earthquakes (separate endorsement) |
| Sudden burst pipe and resulting water damage | Slow leaks, seepage, and the pipe repair itself |
| Liability and guest medical payments | Normal wear, pest/termite damage, neglect |
| AC unit hit by a covered peril (fire, lightning, theft) | AC that dies of age or mechanical breakdown |
Plumbing follows the same rule: a pipe that suddenly bursts and floods a floor is typically paid, but the cost to fix the corroded pipe, plus damage from a leak you left dripping for weeks, usually isn't. Water damage splits the same way — internal water escaping from a system is covered, while water rising from outside or the ground is flood, not homeowners.
AC units trip up many owners. The unit is covered when a listed peril damages it, but a compressor that simply wears out is a maintenance issue. Add equipment-breakdown coverage if you want mechanical failure included.
How is coverage different in Florida and Texas?
In both states, wind is the expensive variable — and it often carries its own percentage deductible instead of a flat dollar amount. In Florida, hurricane deductibles commonly run 2–10% of the dwelling limit, and flood is always excluded. In Texas, wind and hail drive rates; some coastal policies exclude windstorm entirely, pushing owners to Texas Windstorm Insurance Association (TWIA) coverage.
Percentage deductibles surprise people at claim time, so run the math before you buy. On a $400,000 dwelling limit, a 5% hurricane deductible is $20,000 out of pocket — twenty times a typical $1,000 all-peril deductible.
| Dwelling limit | Deductible type | Your out-of-pocket |
|---|---|---|
| $400,000 | Flat $1,000 (standard peril) | $1,000 |
| $400,000 | 2% hurricane | $8,000 |
| $400,000 | 5% hurricane | $20,000 |
| $400,000 | 10% hurricane | $40,000 |
Common mistake: assuming flood and sewer backup are included. They are not in a base policy anywhere — in coastal Florida and Texas you almost always need separate flood coverage plus wind and water-backup endorsements, or a single covered-looking storm can leave you paying tens of thousands yourself.
How do I choose a policy and avoid mistakes?
Choose on coverage adequacy first and premium second — a cheap policy that underinsures your rebuild cost is the expensive one. Work through this checklist before you sign or renew.
- Confirm replacement cost (not actual cash value) on the dwelling and, ideally, on contents.
- Set the dwelling limit to rebuild cost, not the market or purchase price.
- Identify your deductible type — flat dollar vs. percentage — and calculate the dollar figure.
- Check sub-limits on jewelry, electronics, and cash; schedule high-value items separately.
- Price the endorsements you actually need: water/sewer backup, equipment breakdown, and flood.
The most common errors all trace back to a mismatch between what you think you bought and what the policy says. Insuring to market price instead of rebuild cost, ignoring percentage deductibles, and undervaluing items capped by sub-limits are the three that turn into denied or shortfall claims.
When comparing quotes, align the coverage limits, deductible type, and endorsements to be identical first, then compare premiums — otherwise you're comparing a smaller policy to a bigger one and the "cheaper" quote just has less coverage.

Common Questions
What does homeowners insurance cover and not cover in one sentence?
It covers sudden, accidental damage to your home, belongings, and detached structures plus liability and living expenses, but not floods, earthquakes, normal wear, pest damage, or gradual leaks and neglect.
Does homeowners insurance cover water damage from plumbing?
Usually yes when a pipe suddenly bursts and the resulting damage is accidental, but no for slow leaks, seepage, or the cost of repairing the failed pipe itself. Water rising from outside is flood, which needs separate coverage.
Does homeowners insurance cover an AC unit?
It covers your AC when a listed peril damages it — such as fire, lightning, or theft — but not failure from age or mechanical breakdown. Add equipment-breakdown coverage if you want wear-and-tear failures included.
Is flood covered in Florida or Texas?
No. Flood is excluded from standard policies nationwide, so Florida and Texas owners need a separate NFIP or private flood policy, and coastal areas often need a wind endorsement or TWIA coverage as well. Check the official page for current details.
