What Is Dwelling Coverage? Coverage A Explained

If your house burned to the slab tomorrow, would your policy pay to rebuild it? The answer sits in one line of your declarations page: Coverage A, your dwelling limit.

Key takeaways

Dwelling coverage (Coverage A) pays to repair or rebuild your house and anything attached to it, like a garage or deck. It never covers the land [1].
Your limit should match what it costs to rebuild, which can be higher or lower than what the house would sell for [3][5].
Insure for less than 80% of rebuild cost and the standard form can cut payments on partial losses too, not just total losses [1].
Extended replacement cost, guaranteed replacement cost and ordinance or law coverage pay when rebuilding costs more than you planned [1][6].

What is dwelling coverage?

Dwelling coverage is the part of a homeowners policy that pays to repair or rebuild the structure of your home after damage from a covered cause, such as fire or a windstorm. On most policies it’s labeled Coverage A, and people often call it dwelling insurance [1][4].

The standard ISO HO-3 form, the template many insurers use, covers “the dwelling on the ‘residence premises’ shown in the Declarations, including structures attached to the dwelling” [1]. Your belongings, detached buildings and liability are separate coverages with their own limits. For the full policy, see our guide to what homeowners insurance covers.

On an HO-3, your house is covered for any cause the policy doesn’t exclude [1]. That’s broad, but flood, earthquake, wear and tear, and pests are still out. Flood needs separate flood insurance.

What counts as the dwelling?

The dwelling is the house itself and anything built into it or attached to it. Under the standard form, Coverage A includes [1]:

The house: the structure itself, from the foundation to the roof, plus its built-in parts.
Attached structures: an attached garage, deck or porch.
Building materials: materials and supplies on or next to your property that you’ll use to build, alter or repair the house.

Coverage A doesn’t include the land under your house [1]. It also doesn’t cover detached structures. A building separated by “clear space,” or joined only by a fence or utility line, falls under Coverage B, other structures [1].

One detail surprises people. Even though carpeting and household appliances are part of the house, the standard form pays for them at actual cash value, meaning their depreciated value [1]. Awnings and outdoor antennas get the same treatment.

Dwelling vs. other structures vs. personal property

Coverages A, B and C split your property three ways. Here’s how they compare on the standard form:

	Coverage A: Dwelling	Coverage B: Other structures	Coverage C: Personal property
What it covers	House and attached structures	Detached garage, shed, fence	Furniture, clothes, electronics
Typical limit	Rebuild cost of the house [3]	Up to 10% of Coverage A [1]	Often 50% to 70% of Coverage A [3]
How losses are paid	Replacement cost, if you meet the 80% rule [1]	Same for buildings; fences and other non-building structures at actual cash value [1]	Actual cash value, unless upgraded [1]
Covered causes	Anything not excluded [1]	Anything not excluded [1]	16 named perils [1]

Because Coverages B, C and loss of use are often set as percentages of Coverage A, your dwelling limit quietly sizes much of your policy [3][4]. Using Coverage B doesn’t reduce your Coverage A limit [1].

How much dwelling coverage do you need?

You need enough to rebuild your house from the ground up at today’s prices. That figure is called replacement cost. It isn’t your home’s market value, your purchase price, your loan balance or your tax assessment [3][5].

Market value includes the land and the local housing market. Rebuild cost depends on labor, materials and your home’s features. The two can be far apart in either direction, and Washington regulators warn the cost to rebuild “may exceed its current market value or sales price” [3].

Here are two hypothetical homes:

High land value: A house sells for $600,000, but $250,000 of that is the lot. A replacement cost estimate puts the rebuild at $320,000. Insuring at market value would mean paying for coverage you can’t use.
Low land value: An older house sells for $180,000 in a slow market, but rebuilding it to the same quality would cost $260,000. Insuring at market value would leave an $80,000 gap after a total loss.

Insurers use formulas built on the same facts an appraiser uses: square footage, construction materials, floor plan, number and types of rooms, garage type and special features [3][5]. California’s required disclosure adds foundation type, number of stories, and the quality of finishes like flooring, countertops, windows and cabinetry [6].

Get a ballpark figure from our home replacement cost calculator, then ask your agent to run a full estimate. California regulators also suggest an independent estimate from a contractor, architect or appraiser [6].

Will you get replacement cost or actual cash value?

How your dwelling claim is paid matters as much as the limit.

Replacement cost pays to repair or rebuild with materials of like kind and quality, with no deduction for depreciation [1][6]. Actual cash value subtracts depreciation for age and wear [6]. Texas regulators recommend replacement cost if you want to be fully protected [4].

Even with replacement cost, you may get paid in two steps. Under the standard form, the insurer pays actual cash value until repairs are finished. The exception is a small job: under $2,500 and under 5% of your coverage [1]. You can also take the actual cash value first and claim the rest later, as long as you tell the insurer within 180 days that you plan to rebuild [1].

What is the 80% rule?

The standard form pays full replacement cost only if your dwelling limit is at least 80% of the home’s full replacement cost at the time of the loss [1]. Fall short and the insurer pays the larger of two amounts: the actual cash value of the damage, or a share of the repair cost [1].

Say your home would cost $350,000 to rebuild, so 80% is $280,000. You carry $210,000, and a burst pipe causes $20,000 of covered damage.

$210,000 ÷ $280,000 = 75%
75% × $20,000 = $15,000, before your deductible

If the actual cash value of the damage is higher than $15,000, you’d get that instead [1].

One quirk works in your favor. Below-ground foundations, footings and underground pipes, flues and wiring don’t count toward the 80% calculation [1]. Our homeowners coverage guide walks through a second example. Try deductible amounts in our deductible calculator.

Extended and guaranteed replacement cost

These endorsements protect you if rebuilding costs more than your limit, which can happen when construction prices jump after a widespread disaster. California’s disclosure calls that “demand surge” [6].

Option	What it pays
Replacement cost	Repair or rebuild without depreciation, up to your dwelling limit [6]
Extended replacement cost	Extra coverage above your limit, up to a stated percentage or dollar amount [6]
Guaranteed replacement cost	The full cost to repair or rebuild, whatever your dwelling limit [6]

With a $350,000 limit and a 25% extended replacement cost endorsement, for example, you’d have up to $437,500 for the house. The percentage varies by policy, so check yours.

Guaranteed replacement cost isn’t always unconditional. Alaska’s insurance regulator notes that these policies may still require you to insure for at least 80% of rebuild cost [5]. Many companies also offer an automatic adjustment that raises your limit to reflect inflation [5].

What does ordinance or law coverage pay for?

When your home is rebuilt, it usually has to meet today’s building codes. Those upgrades aren’t part of normal replacement cost [1].

The standard form lets you use up to 10% of your Coverage A limit for code-related costs, on top of the dwelling limit [1]. On a $350,000 limit, that’s $35,000. It pays for three things [1]:

Bringing the damaged part of the house up to code.
Demolishing and rebuilding undamaged parts when the law requires the whole building to come down.
Removing debris from that work.

It won’t pay for any drop in your home’s value caused by the law, or for pollution cleanup [1]. If your home is older, ask whether 10% is enough. Texas regulators list extra code coverage among common endorsements [4].

Other extras tied to your dwelling limit

The standard form adds a few more coverages sized off Coverage A [1]:

Trees, shrubs and plants: up to 5% of the dwelling limit, $500 per tree, for named causes like fire, theft and vandalism. Wind isn’t one of them.
Debris removal: an extra 5% of the limit if the damage plus cleanup uses up your dwelling limit.

What does your mortgage lender require?

Lenders protect their collateral, so they care about Coverage A. As of October 2026, Fannie Mae’s rules for the loans it buys say [9]:

The policy must pay on a replacement cost basis. Roofs are the exception and may be covered at actual cash value.
The deductible can’t exceed 5% of the coverage amount. On $350,000, that’s $17,500.
Coverage must include fire, lightning, windstorm, hail, explosion, smoke, aircraft, vehicles, and riot or civil commotion.

Individual lenders can add their own rules. And if your coverage lapses, the lender may buy force-placed insurance. Alaska’s regulator warns it covers only your loan balance and protects the lender, not you [5]. Meeting the lender’s rules doesn’t mean your limit covers a full rebuild.

Dwelling coverage on other policy types

Coverage A works differently outside a standard HO-3.

Dwelling fire policies (DP-1, DP-2, DP-3)

A dwelling fire policy, sometimes called dwelling property insurance, covers a home that isn’t your main residence, such as a rental, vacation home or vacant house [7]. It’s also used when a home doesn’t qualify for a homeowners policy [5][8]. It usually has no liability coverage [7]. Landlords often use one through landlord insurance.

Form	Covered causes for the house	Claims usually paid at
DP-1 (basic)	Named perils only [7][8]	Actual cash value; replacement cost may cost extra [7]
DP-2 (broad)	More named perils, such as falling objects and vandalism [7][8]	Replacement cost [7]
DP-3 (special)	Anything not excluded [7][8]	Varies by insurer; confirm it’s replacement cost [5]

Condos and townhouses (HO-6)

On a condo policy, the association insures the main building. Your HO-6 Coverage A is “walls-in” coverage for [2]:

Alterations, appliances, fixtures and improvements inside your unit.
Property the association agreement makes your responsibility.
Structures you alone own at the property.

That coverage is for named perils only on the standard HO-6 form, not open perils [2]. The right limit depends on what your association’s master policy leaves to you, so read your HOA documents first [3].

A townhouse in a community with an association may be insured the same way; a standalone townhouse you fully own usually needs a regular homeowners policy. Compare options for condo insurance, or see mobile home insurance for manufactured homes.

How to check your dwelling coverage

Here’s how to review your Coverage A:

Find your declarations page. It’s the first page of your policy and lists each coverage limit and deductible [4].
Estimate your rebuild cost. Use the replacement cost calculator for a starting point.
Compare. If your limit is under the estimate, ask your agent for a professional replacement cost estimate.
Ask about endorsements. Extended replacement cost and extra ordinance or law coverage cost money but close real gaps.
Report renovations. Tell your insurer after additions or major improvements, since they change your rebuild cost [3].

Our renewal checklist covers the rest of the policy. An independent agent can quote several insurers’ replacement cost estimates side by side. Find an insurance agent or browse home insurance agencies near you.

Dwelling coverage FAQ

Is dwelling coverage the same as homeowners insurance?

No. Dwelling coverage is one part of a homeowners policy. A standard homeowners policy also includes other structures, personal property, loss of use, personal liability and medical payments to others [4].

Does dwelling coverage include the land?

No. The standard homeowners form says it doesn’t cover land, including the land your house sits on [1]. That’s one reason your dwelling limit can be well below your home’s market value.

Does dwelling coverage cover a detached garage?

No, a detached garage falls under Coverage B, other structures. That includes a garage joined to the house only by a fence or utility line. On the standard form, Coverage B is capped at 10% of Coverage A [1].

Does dwelling coverage cover the foundation?

The foundation is part of the dwelling, so dwelling coverage pays when a covered cause like fire damages it. But settling, cracking and earth movement are excluded under the standard homeowners form [1].

The bottom line

Dwelling coverage pays to repair or rebuild your house, and its limit drives much of the rest of your policy. Set it at rebuild cost, not market value. Keep it above 80% of that figure, and consider extended replacement cost and extra ordinance or law coverage if building costs or codes could outrun your limit. More guides are on our insurance blog.
