HO-3 vs HO-5: What the Two Homeowners Forms Cover and Who Should Buy Which

The difference between an HO-3 and an HO-5 homeowners policy is almost entirely about your belongings. Both forms insure the house itself on an open-peril basis, meaning any cause of loss that is not specifically excluded is covered. The HO-3 then insures your personal property only against a list of named perils, while the HO-5 insures personal property on the same open-peril basis as the building.^[1][2] The NAIC's definitions are the shortest version: the HO-3 "provides 'all-risks' coverage on buildings, broad named-peril coverage on personal property"; the HO-5 "provides 'all-risks' coverage on buildings and personal property".^[1]

That one change moves the burden of the unusual loss. Under an HO-3, a damaged sofa is covered only if you can point to a listed peril such as fire, theft or a burst pipe. Under an HO-5, the sofa is covered unless the insurer can point to an exclusion. The HO-5 costs more for that reason and is not offered by every carrier or on every home.^[2] If you are deciding between the two, start a homeowners quote and ask for both forms priced side by side; the gap in premium is the actual cost of the broader contents coverage for your house.

What do named perils and open perils mean?

Everything in this comparison rests on two definitions. Named-peril coverage pays only for loss caused by the perils specifically listed as covered in the policy.^[4] Open-peril coverage, historically called all-risk and now often labelled special form, insures against loss from all causes except those the policy specifically excludes.^[5] Maryland's insurance regulator explains the practical consequence: under a named-peril policy, "if your property is damaged due to a peril not listed in the policy, your insurer will not pay for the damage", while an open-peril policy "typically provides broader protection than a named peril policy, as it tends to cover more causes of loss".^[3]

The named-peril list on an HO-3's contents coverage is the "broad form" list, the same perils an HO-2 covers on the whole house. Wisconsin's regulator enumerates it: fire or lightning, windstorm or hail, theft, explosion, smoke, damage from vehicles and aircraft, glass breakage, vandalism and malicious mischief, riot or civil commotion, building collapse, freezing or accidental discharge of water or steam from plumbing, heating or air conditioning systems and appliances, falling objects, weight of ice, snow or sleet, and rupture of steam or hot water heating systems.^[2] That is a long list, and it covers the great majority of things that happen to furniture. What it does not cover is the loss that fits no category: the laptop knocked off the counter, the wine collection ruined by a heat wave when the air conditioning failed, the rug stained by a spilled can of paint. Under an HO-3 those are your problem. Under an HO-5, they are covered unless excluded.

Open peril is not "everything". Both forms exclude the same catalog of causes: flood, earthquake, neglect, wear and tear, war, nuclear accident, ordinance enforcement and the rest.^[3] The HO-5's advantage is confined to the space between the named-peril list and the exclusion list.

HO-3 vs HO-5: side by side

The market shares come from the NAIC's 2026 report on 2023 data: the HO-3 "remains the most common policy sold by far", at 79.5% of owner-occupied exposures nationally, and in California HO-3 policies made up 49.3% of all house-years across every form including renters and condo policies, against 9.4% for the HO-5.^[1] Wisconsin's guide supplies the availability row: the HO-5 "is not often sold today" as a distinct form, "not all insurers offer HO-5, but many offer similar policies", and an HO-3 can be extended to comprehensive contents coverage with a special personal property endorsement.^[2]

Does the HO-5 pay replacement cost on contents?

Not automatically, and this is where most online comparisons go wrong. Perils and valuation are separate levers. Perils decide whether a loss is covered; valuation decides how much the insurer pays once it is. Wisconsin's regulator states the default plainly: "Most policies pay for losses to your contents on an actual cash value basis", with replacement cost coverage "available for an additional premium".^[2] California's Department of Insurance describes the same choice and defines actual cash value as what it would cost to replace the item less depreciation.^[6]

Many carriers bundle replacement cost on contents into their HO-5 package, and many sell it as an endorsement on the HO-3. Either way, the fact that decides your claim check is on the declarations page, not in the form number. Our guide to actual cash value vs replacement cost works through the arithmetic; the short version is that on a ten-year-old sofa the two settlements can differ by most of its price.

What drives the cost difference?

The HO-5 costs more than the HO-3 on the same house because the insurer is promising to pay for contents losses it cannot enumerate in advance. How much more is a carrier-by-carrier answer, and we will not invent a percentage. Maryland's regulator gives the sensible instruction: "ask for a price quotation on both an all-risk policy and a named peril policy", and if the difference is affordable, take the broader coverage.^[3]

What moves the gap for your own quote:

• Contents limit. Contents coverage is often set around 50% of the dwelling limit by default.^[6] The more you insure, the more the open-peril promise is worth and costs.
• Replacement cost on contents. Bundled or endorsed, it adds premium on either form.^[2]
• Underwriting tier. Carriers reserve their comprehensive forms for homes that meet their preferred criteria on age, condition and claims history; the HO-5 is partly a signal that the house qualified.
• Location. In California, wildfire exposure dominates the price of the dwelling coverage on both forms and can decide whether either is offered at all.

Who should choose an HO-3, and who should choose an HO-5?

Choose the HO-3 if your belongings are ordinary, your budget is tight, and the broad-form list already covers the losses you worry about. It is the form four out of five owner-occupants carry for a reason.^[1] Choose the HO-5, or an HO-3 with the comprehensive contents endorsement, if you own things worth arguing about, if you would rather the insurer carry the burden of proving an exclusion than you carry the burden of proving a peril, or if the quoted difference is small enough that the question answers itself.

Either way, read the underlying form. Our reference page on the HO 00 03 special form walks through the standard HO-3 section by section, and the glossary entry for peril defines the word every one of these comparisons turns on.

Which forms are actually available in California?

For a well-maintained home in a low-hazard area, both. For a home in a high wildfire-hazard zone, the question is often not HO-3 or HO-5 but whether any admitted carrier will write a homeowners package at all. When they will not, the fallback is the California FAIR Plan, which is neither form: it is a named-peril dwelling policy covering fire or lightning, internal explosion and smoke, with extended coverage and vandalism as options and no liability coverage.^[7] Owners typically pair it with a difference in conditions policy for the perils it leaves out. Our California FAIR Plan guide and DIC insurance guide explain that pairing.

Between those poles sit the surplus lines and specialty markets that write wildfire-exposed homes on HO-3-style forms with their own terms. Guides to two of them, Delos Insurance and Annex Risk, describe how those programs work. If you are not sure which market your home falls into, request a homeowners quote and let a broker find out; the overview at homeowners insurance explains what the quote will ask.

This guide is for educational purposes and summarizes regulator consumer guides and NAIC market data. Your policy's specific terms, conditions, and endorsements control; insurers file their own versions of each form. Menlo Insurance Services (CA license 6020106) does not guarantee that any coverage or price will be available; talk to a licensed broker about your actual exposures.

The Bottom Line

HO-3 and HO-5 insure the house identically and your belongings differently: named perils on the HO-3, open perils on the HO-5. The HO-5, or an HO-3 with a comprehensive contents endorsement, shifts the burden of the odd loss to the insurer at a higher premium. Decide valuation separately, because neither form guarantees replacement cost on contents, and in California check first whether the house qualifies for a homeowners package at all.
