Home Insurance Explained: Cover, Cost and Comparison

Home insurance is a package contract with two halves. Section I pays to repair or rebuild your property after a covered event. Section II pays when you are legally responsible for someone else's injury or damage. Everything else — limits, deductibles, exclusions — decides how much of each half you actually get.

The Consumer Financial Protection Bureau describes it plainly: homeowner's insurance "pays for losses and damage to your property if something unexpected happens, like a fire or burglary," and lenders generally require proof of it because the house is their collateral. That requirement is why most people buy the policy. It is not why the policy is worth understanding.

What does a homeowners policy actually pay for?

A standard homeowners package splits into six lettered coverages, and the declarations page lists them in that order. The NAIC's Shopping Tool for Homeowners Insurance sets out the layout on its sample declarations page:

• Coverage A — Dwelling. The house itself.
• Coverage B — Other structures. The detached garage, the fence, the shed.
• Coverage C — Personal property. Contents. Furniture, clothes, electronics.
• Coverage D — Loss of use. Additional living expenses while the house is uninhabitable, often written as "actual loss sustained" rather than a dollar limit.
• Coverage E — Personal liability. Legal defence and damages when you are held responsible for someone else's bodily injury or property damage.
• Coverage F — Medical payments to others. A small no-fault limit, typically a few thousand dollars, that pays a guest's medical bills without anyone establishing blame.

Coverages A through D are Section I, the property side, and share the property deductible. Coverages E and F are Section II, the liability side, and normally carry no deductible at all. A full walk-through of what a homeowners policy covers peril by peril sits alongside this article.

Which policy form are you being quoted?

Homeowners policies are sold on standardised forms, and the form number determines the breadth of cover before any endorsement is added. The NAIC's homeowners report, Data for 2023 published in July 2026, defines them and counts them.

Figures: NAIC, Dwelling Fire, Homeowners Owner-Occupied, and Homeowners Tenant and Condominium/Cooperative Unit Owner's Insurance Report: Data for 2023, Figure 1 and Table 4 (countrywide). Averages are total written premium divided by house-years, so they mix together every house size, state and deductible on that form.

The HO-3 is the default. NAIC counts it at 79.45% of homeowners owner-occupied written exposures countrywide and 55.1% of all policy exposures including renters and condo forms. If nobody has told you which form you are being quoted, it is almost certainly this one.

Why does the HO-3 treat your building and your belongings differently?

Because it is two different promises stapled together. NAIC defines the HO-3 as providing "all-risks" coverage on buildings and "broad named-peril coverage on personal property" — the house is covered against any cause of loss except those the policy lists as excluded, while your furniture is covered only if the cause of loss appears on a list inside the policy.

The valuation basis usually splits the same way. The NAIC shopping tool states that the special form policy "covers your home for its replacement cost value and your personal property for its actual cash value." Replacement cost is what it costs to rebuild with materials of like kind and quality. Actual cash value is that figure minus depreciation for age and wear.

That single difference does more to determine claim outcomes than any other clause in the document, which is why replacement cost and actual cash value get their own explainer.

What is excluded no matter which form you buy?

Flood and earthquake. The NAIC shopping tool is unambiguous: "Most homeowners insurance policies do NOT cover damage from floods or earthquakes." The CFPB says the same thing about standard homeowner's insurance. Mold, gradual deterioration, foundation settling and ordinary wear and tear are the other recurring gaps, and the NAIC guide lists them among the questions to put to an insurer before buying.

Flood is the expensive one, because it is also the one people assume is included. The Texas Department of Insurance sets out the alternative: a National Flood Insurance Program policy covers the building up to $250,000 and belongings up to $100,000, on separate limits, and "most flood policies have a 30-day waiting period before kicking in." Buying in the week a storm is named does not work.

Earthquake is normally an endorsement rather than a separate policy, and NAIC's report notes that earthquake premiums are excluded from its homeowners premium data entirely — so any average premium figure you read, including the ones in the table above, does not include it. Water is the peril where the covered/excluded line is finest — burst pipe versus rising creek versus backed-up drain are three different answers, mapped in which water damage home insurance covers.

How much dwelling coverage is the right amount?

Coverage A is meant to track the cost to rebuild the structure, not the price the house would sell for and not the balance of the mortgage. Those three numbers routinely differ by six figures in either direction, because market value includes land and location, and a loan balance reflects how long you have been paying.

NAIC's guidance is blunt about the consequence: "Insuring your home for less than the cost to rebuild it means you may have to pay thousands of dollars out of pocket to rebuild your home if it is destroyed." Its suggested method is to ask a local builder or real estate agent for the average new-construction cost per square foot for a similar home in the same community.

For scale, NAIC found that 55.2% of dwelling fire and homeowners owner-occupied policies countrywide in 2023 were written for coverage amounts between $150,000 and $400,000. That is where the middle of the market sits — it is not a recommendation for any particular house.

How does the deductible work when a storm hits?

Most policies carry a flat dollar deductible for ordinary losses and a separate percentage deductible for wind, hail or named storms — and the percentage applies to the dwelling limit, not to the size of the claim.

NAIC's hurricane deductibles topic page, updated 2 June 2025, records that nineteen states and the District of Columbia have some form of hurricane or named storm deductible in place, and that the deductible "can vary from 1% to as high as 15%" of the home's insured value.

The arithmetic matters more than the percentage. On a dwelling limit of $400,000, a 2% wind deductible is $8,000 the homeowner pays before the insurer pays anything; at 5% it is $20,000. The sample declarations page in the NAIC shopping tool shows exactly this structure — a $500 deductible for other losses sitting beside a 10% hurricane/wind deductible on the same policy.

The flat-versus-percentage mechanics, the state trigger rules and where the raise-your-deductible advice fails are worked through in how home insurance deductibles actually work.

What are the odds a policy is ever used?

Low in any single year, and lopsided by peril. The Insurance Information Institute publishes claim frequency and severity by cause of loss from ISO, a Verisk business, averaged over 2018 to 2022.

Figures: Insurance Information Institute, citing ISO (a Verisk Analytics business), five-year average 2018–2022.

Read the two columns against each other. Wind and hail generate roughly twelve times as many claims as fire and lightning, and fire and lightning cost roughly six times as much per claim. III reports that 5.5% of insured homes experienced a claim in 2022 — meaning about 19 in 20 insured homes went the year without one. The policy is not priced for the year you claim. It is priced for the fire.

Why do premiums rise when nothing about the house changed?

Because the price reflects the pool, not the policyholder. In August 2026 the NAIC published the first national analysis of homeowners market trends built from seven years of Market Conduct Annual Statement data, covering 2018 to 2024. It found that average premium per policy rose in every NAIC region since 2018, with inflation-adjusted increases ranging from 18.3% to 43.3% — that is on top of inflation, not including it.

The same analysis found company-initiated non-renewal rates increased between 96% and 216% depending on region, while the market itself stayed crowded: 715 companies wrote homeowners coverage in 2024, with underwriting results improving across all four NAIC regions. A market can be competitive and unaffordable simultaneously. The mechanics of why home insurance premiums rise — reinsurance, replacement cost inflation, catastrophe modelling — are unpacked separately.

Is the broader HO-5 form really the expensive option?

Countrywide, the HO-5 averages more than the HO-3. Compared at the same amount of insurance, it averages less — in almost every coverage band NAIC publishes.

Figures: NAIC, Homeowners Insurance Report: Data for 2023, Table 4, countrywide averages by policy form and amount of insurance.

Every band from $150,000 through $999,999 in NAIC's countrywide table shows the HO-5 average below the HO-3 average, and the pattern reverses only above $1,000,000 of coverage. The combined average still favours the HO-3 because HO-5 policies cluster at higher coverage amounts, which pulls the blended figure up. That is a composition effect, not a price on the form.

What this does not show is that switching form saves money. These are averages of premium divided by exposure, not like-for-like risk comparisons, and insurers typically offer the HO-5 to newer, better-maintained homes and to preferred applicants — the same homes that would be cheaper on any form. The honest conclusion is narrower and more useful: the assumption that the broader form is a costly luxury is not supported by the countrywide data, and the price difference is a question worth putting to a licensed provider rather than assuming the answer.

Where this explainer stops being accurate

Every generalisation above has a boundary, and these are the ones that bite:

• Texas is not standard. NAIC's report notes that the Texas Department of Insurance historically developed its own home insurance policy forms, "similar, but not identical, to homeowners policy forms countrywide," and some insurers still use them. Form-number reasoning is weakest there.
• Condos and rentals use different forms entirely. The HO-4 covers a tenant's personal property and the HO-6 covers a condo or co-op owner's contents plus the building items they hold an insurable interest in. NAIC counts 76.53% of that segment on the HO-4 form.
• Endorsements override the base form. A policy can be an HO-3 on paper and still settle roof claims on a depreciation schedule, cap water backup at $10,000, or exclude masonry veneer from earthquake cover — all of which appear on the NAIC sample declarations page as ordinary options.
• Older homes may not qualify for replacement cost at all. The HO-8 exists precisely for houses where rebuild cost greatly exceeds market value, and it settles on repair cost.
• Availability is regional and moving. With non-renewals up sharply since 2018 on NAIC's own numbers, the form and price available in a coastal or wildfire-exposed county may look nothing like the countrywide averages here.

Nothing in this article is a description of any particular policy. Coverage, wording and settlement terms come from the policy documents issued by the licensed provider, and those documents govern.

What to have in front of you before comparing providers

The NAIC shopping tool lists what an insurer will ask for, and having it ready is what makes two quotes comparable rather than merely different: year built and year purchased, square footage of living area, roof type and approximate age, exterior construction, kitchen and bath finishes, the approximate age of the plumbing, electrical, heating and air conditioning systems, distance to the fire department and to a hydrant, and an inventory with approximate values of jewellery, firearms, art and other high-value property that carries sublimits.

Then compare the same five lines across every quote: the Coverage A limit, whether Coverage A and Coverage C settle on replacement cost or actual cash value, the flat deductible, the wind or named-storm deductible, and the Section II liability limit. NAIC's guidance is to get at least three quotes before buying.
