What Does Homeowners Insurance Actually Cover? Coverages, Gaps and Flood (2026)
A plain-English walk through the six parts of a homeowners policy, what is excluded, and the flood and water gaps that catch most owners off guard.
Estimate at a glance2026
A standard homeowners policy covers your dwelling, other structures, belongings, extra living costs, liability and guests' medical bills. It usually excludes flood, earthquake, wear and tear and poor maintenance, and often limits sewer backup unless you add an endorsement. Flood coverage is separate; NFIP policies generally have a 30-day waiting period, and under FEMA's Risk Rating 2.0 most annual increases are capped at 18%.
Most people buy homeowners insurance because the lender requires it, and never read the policy until something goes wrong. The biggest surprises are not in what the policy covers but in what it leaves out. Here is how a standard policy is built, and where the gaps usually are.
The six parts of a homeowners policy
| Coverage | What it pays for |
|---|---|
| A: Dwelling | Repairing or rebuilding the house itself |
| B: Other structures | Detached garages, sheds, fences |
| C: Personal property | Your belongings, inside or away from home |
| D: Loss of use | Extra living costs if you cannot live at home during covered repairs |
| E: Personal liability | Injuries or damage you cause to others, including legal defense |
| F: Medical payments | Small medical bills for guests hurt on your property, regardless of fault |
Each coverage has its own limit, and some items within personal property, such as jewelry or collectibles, often have lower sub-limits unless you schedule them separately.
HO-3, HO-5 and HO-8: the main policy types
- HO-3 is the most common. It usually covers the dwelling against all risks except those specifically excluded, and covers personal property against a list of named perils such as fire, theft and windstorm.
- HO-5 extends broader, all-risks-except-excluded coverage to your personal property as well. It costs more and is often available for newer, well-maintained homes.
- HO-8 is designed for older homes where rebuilding to original standards would cost far more than the home's value. It typically pays on a repair or actual cash value basis rather than full replacement.
Your policy's declarations page names the form and lists your limits and deductibles.
Replacement cost vs actual cash value
- Replacement cost pays what it costs to repair or replace with similar materials today, minus your deductible.
- Actual cash value subtracts depreciation for age and wear, so older items and roofs receive less.
Many policies now pay roof claims differently from the rest of the house. An insurance industry endorsement, HO 04 93, switches wind and hail losses to roof surfacing to actual cash value, and some insurers use roof payment schedules based on age. See how long a roof lasts for why this matters.
What is usually not covered
- Flood from rising water, storm surge or overflowing rivers
- Earthquake and earth movement
- Wear and tear, rot and poor maintenance
- Gradual leaks and continuous seepage; see signs of a hidden water leak
- Pests such as termites and rodents
- Mold, except limited coverage when it results from a covered event
- Sewer or drain backup, unless you add a water backup endorsement
- Ordinance or law costs to bring a damaged home up to current code, beyond a small limit unless you add coverage
The water gaps that catch owners off guard
Water causes some of the most expensive claims, and coverage depends on where the water came from:
| Source | Standard policy? |
|---|---|
| Burst pipe, sudden and accidental | Usually covered |
| Slow leak over months | Usually excluded |
| Sewer or drain backup | Only with an endorsement |
| Flood or surface water | Excluded; needs flood insurance |
| Roof leak from storm damage | Usually covered, roof terms may apply |
If a freeze bursts a pipe in a home left unheated, freeze damage can also be excluded. See how to prevent frozen pipes.
Flood insurance, explained
Flood coverage comes mainly from the National Flood Insurance Program, run by FEMA, and from private insurers.
- Waiting period: NFIP policies generally take effect 30 days after purchase, with limited exceptions, so you cannot buy coverage the day before a storm.
- Pricing: FEMA's Risk Rating 2.0 prices policies based on each property's flood risk. By law, most annual increases are capped at 18%, and FEMA says 96% of policyholders see decreases or increases of no more than $20 a month.
- Community discounts: homes in communities that join FEMA's Community Rating System can receive discounts from 5% to 45%.
Flooding can happen outside high-risk zones, so ask for a quote even if your lender does not require it.
Deductibles and how a claim is paid
When you file a claim, the insurer subtracts your deductible from the covered amount. Many policies have a flat deductible for most claims, such as $1,000 or $2,500, and a separate wind, hail or hurricane deductible set as a percentage of your dwelling coverage in storm-prone states. On a home insured for $300,000, a 2% wind deductible means you pay the first $6,000 of a wind claim. Know both numbers before a storm.
Scheduling valuables and extra liability
Standard policies limit how much they pay for certain belongings, such as jewelry, watches, collectibles and firearms, often far below their value. If you own items like these, ask about scheduling them individually or adding a valuables policy.
Liability limits matter too. If you have significant savings or assets, an umbrella policy can add liability coverage above your homeowners limit for a relatively modest cost. Ask your agent for a quote when you review your policy.
How to check your own coverage
- Find your declarations page and note the policy form, limits and deductibles
- Check whether the dwelling and roof are paid at replacement cost or actual cash value
- Look for wind, hail or hurricane deductibles stated as a percentage
- See whether water backup and ordinance or law coverage are included
- Decide whether you need flood or earthquake coverage for your area

Questions homeowners ask
What's the difference between HO-3, HO-5 and HO-8?
HO-3 is the most common, with broad dwelling coverage and named-peril coverage for belongings. HO-5 extends broad coverage to belongings. HO-8 is for older homes and typically pays on a repair or actual cash value basis.
Does homeowners insurance cover flooding?
No. Flood from rising or surface water is excluded and requires separate flood insurance from the NFIP or a private insurer.
Is sewer backup covered?
Usually only if you add a water backup endorsement to your policy.
What is replacement cost vs actual cash value?
Replacement cost pays to replace with similar materials today. Actual cash value subtracts depreciation, so older items and roofs receive less.
Is there a waiting period for flood insurance?
NFIP policies generally take effect 30 days after purchase, with limited exceptions.
How much can flood insurance go up each year?
Under FEMA's Risk Rating 2.0, most annual increases are capped at 18% by law.
