How this article was made: Drafted with AI assistance, then checked line by line against the primary sources listed at the end of this page (the NAIC Consumer's Guide to Home Insurance and NAIC homeowners policy-form definitions, Insurance Information Institute (Triple-I) coverage tables, the Texas Department of Insurance home insurance guide and policy-form order, and the CFPB), fetched on October 16, 2026. Worked examples use simple illustrative numbers, not real accounts. Rules, policy wording, and state laws change, so re-check the linked sources and your own documents before you act.

If you have ever compared two homeowners quotes and seen "HO-3" on one and "HO-5" on the other, you have met the policy-form system. These codes are not marketing labels. They describe the basic contract: which property is covered, and whether it is covered against a list of named causes of loss or against everything the policy does not exclude. Two quotes with the same dwelling limit can pay very differently after a loss if they are written on different forms.

This guide walks through every common form from HO-1 to HO-8, spends most of its time on the HO-3 vs HO-5 decision that most owners of a house actually face, and shows you how to confirm which form you have. If you are brand new to the topic, start with our beginner guide to homeowners insurance and come back here for the form-by-form detail.

Why policy forms exist

Eight homeowners policy forms in one list: HO-1 basic, HO-2 broad, HO-3 special, HO-4 renters, HO-5 comprehensive, HO-6 condo, HO-7 mobile or manufactured home, HO-8 modified coverage for older homes.

The National Association of Insurance Commissioners (NAIC), the group of state insurance regulators, explains in its Consumer's Guide to Home Insurance that "a type of homeowners policy is called Form," and that the perils your policy covers depend on the type you buy. A peril is simply a cause of loss, such as fire, windstorm, or theft. The NAIC guide adds that all policy types except the dwelling fire form cover your dwelling and its contents, plus personal liability and medical payments.

Most U.S. insurers build their homeowners policies on standardized forms written by an industry advisory organization and then filed with state regulators. In Texas, for example, the Department of Insurance published a commissioner's order approving ISO forms numbered HO 00 02, HO 00 03, HO 00 04, HO 00 05, HO 00 06 and HO 00 08. That is where the shorthand "HO-3" comes from: it is the third homeowners form in the series. Insurers can also write their own forms or add state-specific endorsements, so the label is a starting point, not a guarantee of identical wording.

The important idea is that the form decides the structure of coverage, while your declarations page decides the dollar limits and deductibles. You need both to know what a policy will actually pay.

Named-peril vs open-peril coverage

Comparison of named-peril and open-peril coverage: named peril pays only for causes listed in the policy, open peril pays for any cause not excluded, and the burden of proof differs.

Every form falls into one of two coverage styles, sometimes mixed within the same policy.

Named-peril coverage pays only if the loss was caused by one of the perils listed in the policy. If the cause is not on the list, there is no coverage.
Open-peril coverage, also called all-risk or special-form coverage, pays for direct physical loss from any cause that the policy does not specifically exclude.

The Texas Department of Insurance puts it plainly: all-risk policies "cover any event that the policy doesn't specifically exclude," while named-peril policies "cover only the events listed in the policy." TDI also warns that all-risk policies "don't cover everything" and usually exclude termites, wear and tear, sewer backups, floods, and earthquakes.

There is a practical difference in a dispute, too. Under a named-peril form, the question is whether your loss fits one of the listed perils. Under an open-peril form, the question becomes whether one of the exclusions applies. That is one reason open-peril coverage is generally treated as broader protection, and why it usually costs more.

HO-1 through HO-8, one form at a time

Number of named perils by form from the Triple-I table: HO-1 and HO-8 list 10 perils, HO-2 lists 16 perils, and HO-3 personal property lists 16 perils while the HO-3 dwelling is open peril.

The Insurance Information Institute (Triple-I) publishes a coverage table by policy type that lists 16 named perils and shows which forms include each one. Combined with the NAIC's own policy-form definitions, it gives a clear map:

HO-1 Basic form

Covers a short list of named perils. In the Triple-I table, HO-1 includes the first 10: fire or lightning, windstorm or hail, explosion, riot or civil commotion, aircraft, vehicles, smoke, vandalism or malicious mischief, theft, and volcanic eruption.

HO-2 Broad form

Adds six more named perils, for 16 in total: falling objects; weight of ice, snow or sleet; accidental discharge or overflow of water or steam from plumbing, heating, air-conditioning, sprinkler systems or household appliances; sudden tearing apart or bulging of certain heating and cooling systems; freezing of those systems; and sudden damage from artificially generated electrical current.

HO-3 Special form

Covers the house and other structures on an open-peril basis, and personal property against the 16 named perils. Triple-I's table describes the dwelling side as "all perils except flood, earthquake, war, nuclear accident, landslide, mudslide, sinkhole and others specified in your policy." The NAIC calls the special form "the most popular of all homeowners forms."

HO-4 Renters (contents broad) form

Covers a tenant's personal property against broad named perils, plus liability. It does not insure a building, because the renter does not own one.

HO-5 Comprehensive form

The NAIC definitions describe HO-5 as providing "open perils for both dwelling and personal property." In other words, it extends the HO-3 approach to your belongings.

HO-6 Condo unit-owners form

For owners of a condominium or co-op unit. The NAIC says it covers "the real property interest and the personal property" of unit owners, which usually means the parts of the unit the association's master policy does not cover.

HO-7 Mobile or manufactured home form

Per the NAIC definitions, HO-7 covers the home's structure on an open-peril basis and personal property on a named-peril basis.

HO-8 Modified coverage form

Designed for older homes where, in the NAIC's words, "the cost to rebuild is greater than the market value." It covers the same short list of perils as the basic form, and the Texas order notes its loss-settlement terms for buildings are more restrictive than other forms and limit on-premises theft to $1,000 unless endorsed.

The NAIC guide also mentions a dwelling fire form, which covers only the structure, with no personal property or liability coverage. It is used for vacation homes, rentals, and situations where other coverage is hard to find, and it is the type of policy a lender may buy for you if you let your own policy lapse.

HO-3 vs HO-5: the real difference

HO-3 versus HO-5: both cover the dwelling on an open-peril basis, but HO-3 covers personal property for named perils while HO-5 covers personal property on an open-peril basis.

For a typical single-family house, the choice usually comes down to HO-3 or HO-5. On the house itself, they work the same way: both use open-peril coverage for the dwelling and other structures. The difference is how your belongings are covered.

HO-3: belongings are covered only for the 16 named perils. If a cause of loss is not on that list, belongings are not covered, even though the same event might be covered for the building.
HO-5: belongings are covered on an open-peril basis, so the question becomes whether an exclusion applies.

The Texas order describes HO 00 05 the same way: it is "similar to the Homeowners 3-Special Form except that Coverage C-Personal Property provides coverage against the risk of direct physical loss with certain exceptions." Texas also has its own state forms, and that order notes the ISO HO-3 is analogous to the Texas HO-B and the ISO HO-5 to the Texas HO-C.

What HO-5 does not do is remove the big exclusions. Flood and earthquake are still excluded. Wear and tear is still excluded. Dollar sublimits for categories such as jewelry still apply unless you schedule items: Triple-I's Am I Covered? brochure notes that a standard policy typically provides only $1,000 to $2,000 for theft of jewelry. Whether your belongings are settled at replacement cost or actual cash value is a separate feature, so confirm it on the declarations page rather than assume it comes with the form.

When HO-5 may be worth pricing

You own a lot of valuable personal property relative to your dwelling limit.
You want broader protection for accidental damage to belongings that might not fit a named peril.
The price difference in your area is small enough that the broader contents coverage is worth it to you.

When HO-3 may be enough

Most of your financial risk is in the structure, not the contents.
You plan to add specific endorsements, such as a scheduled personal property floater for jewelry, instead of upgrading the whole form.
HO-5 is unavailable for your home type or location, which can happen.

This is a pricing and risk-tolerance decision, not a right-or-wrong answer. Ask for quotes on both forms with identical limits and deductibles so the comparison is fair.

What neither form covers

Five exclusions that apply even to open-peril HO-3 and HO-5 forms: flood, earthquake and earth movement, wear and tear and maintenance, termites and pests, and sewer or drain backup unless endorsed.

Upgrading the form does not fill every gap. Triple-I lists four big categories that standard homeowners policies generally do not cover: floods, earthquakes, damage from lack of maintenance (including mold and termites), and sewer backup. The NAIC guide adds that many insurers sell earthquake coverage as a separate policy or endorsement, and that you may be able to buy endorsements for mold or for sewer, drain and sump pump backup.

Flood deserves special mention because it is the most common surprise. If your home is in a flood-prone area, read our guide on when homeowners need flood insurance. For the broader list of covered and excluded events, see what homeowners insurance covers and does not cover.

There is also a geographic exception. The NAIC notes that while homeowners policies in most states cover windstorm and hail, policies in some coastal areas exclude it, in which case you need a separate wind policy.

Condos, renters, mobile homes, and older homes

Specialty forms and when they fit: HO-4 for renters, HO-6 for condo unit owners, HO-7 for mobile and manufactured homes, HO-8 for older homes where rebuild cost exceeds market value, and dwelling fire forms for rentals and vacant homes.

If you do not own a standard detached house, the right form changes:

Renters use HO-4. Our renters vs homeowners insurance guide explains the gap between the two.
Condo and co-op owners use HO-6. Before choosing limits, read the association's master policy and bylaws so you know which walls, fixtures and improvements are your responsibility.
Mobile and manufactured home owners use HO-7 or a similar specialty form. The NAIC guide warns that if a mobile home has wheels and does not rest on blocks or a permanent foundation, in most states you will buy a form of automobile insurance, which offers far less coverage.
Owners of older homes sometimes end up with HO-8 when the cost to rebuild with original materials is far above market value. Because coverage is narrower, it is worth asking whether an HO-3 is available with appropriate limits.

Why lenders and claims care about the form

Your mortgage lender cares about the form because the house is its collateral. The CFPB explains that lenders generally require homeowners insurance as a condition of the loan, and TDI notes that if you owe money on your house, your lender will probably require an all-risk policy. If coverage lapses, the NAIC guide says the lender will likely insure the home itself, at a premium that "might be much higher," with coverage limited to the structure.

At claim time, the form decides the first question the adjuster asks: is this cause of loss covered? Under an HO-3, a damaged sofa is covered only if one of the 16 named perils caused the damage. Under an HO-5, the sofa is covered unless an exclusion applies.

Illustrative example (not a real claim): A guest accidentally knocks a large television off a wall mount and the screen shatters. Accidental breakage by a person is not one of the 16 named perils in the Triple-I list, so under a standard HO-3 the television may not be covered for that cause. Under an HO-5, it may be covered unless the policy excludes it. Your own policy wording decides the outcome, which is why reading it matters more than the label.

How to find your form and read it

Five steps to find your form: open the declarations page, find the form number such as HO 00 03, check Coverage A and C loss basis, read the perils insured against and exclusions, and ask the agent about endorsements.

Open your declarations page. The NAIC guide says the first page of the policy summarizes coverages, limits and deductibles. The form number, such as HO 00 03 or HO 00 05, is often listed there or in a forms schedule.
Check the form edition and endorsements list. Endorsements can add or remove coverage, and some change the loss-settlement basis.
Confirm how the house and belongings are settled. Look for replacement cost or actual cash value for both Coverage A (dwelling) and Coverage C (personal property).
Read "Perils Insured Against" and "Exclusions." TDI recommends reading the perils list to know exactly what a named-peril policy covers.
Ask your agent specific questions. For example: "Is personal property named-peril or open-peril on this quote?" and "What would it cost to add water backup coverage?"

The NAIC also notes that you should receive the policy itself, not a photocopy, and if it does not arrive within 30 days you should contact the insurer.

Shopping tips when comparing forms

Match everything except the form. Use the same dwelling limit, deductible, liability limit and endorsements so you can see what the form upgrade really costs.
Price the alternatives. Compare an HO-5 quote with an HO-3 plus targeted endorsements, such as a scheduled personal property floater.
Check your state insurance department. The NAIC says many departments publish premium comparison guides and complaint indexes.
Keep an inventory either way. The NAIC recommends a room-by-room home inventory with photos or video, stored away from the home and updated annually.

FAQ

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

Both cover the house on an open-peril basis. HO-3 covers personal property only for named perils, while HO-5 covers personal property on an open-peril basis, as described in the NAIC definitions and the Texas order.

Is HO-3 the most common homeowners policy?

Yes. The NAIC calls the special form the most popular homeowners form, and Triple-I describes HO-3 as the most common homeowners policy in the United States.

Does an HO-5 policy cover flood or earthquake?

No. Open-peril forms still exclude flood and earthquake. Flood requires a separate flood policy, and earthquake requires a separate policy or endorsement, according to Triple-I.

What does HO-6 cover?

HO-6 is the condo or co-op unit-owners form. The NAIC says it covers the unit owner's real property interest and personal property; the association's master policy covers other parts of the building.

What is an HO-8 policy used for?

HO-8 is a modified coverage form for older homes where the cost to rebuild is greater than market value. It covers a short list of named perils, per the NAIC guide.

How do I know which form my policy uses?

Check the declarations page or forms schedule for a form number such as HO 00 03. If it is unclear, ask your insurer or agent in writing.

Is HO-5 always better than HO-3?

Not automatically. HO-5 gives broader contents coverage but usually costs more and may not be offered for every home. Compare quotes with identical limits and deductibles before deciding.
