Quick answer: HO-3 and HO-5 are the two most common homeowners policy forms for owner-occupied houses. Both cover the dwelling and other structures against any cause of loss that is not specifically excluded. The difference is your belongings: an HO-3 covers personal property only for a list of named perils, while an HO-5 covers personal property on the same open-perils basis as the house. HO-5 policies usually cost more and may be limited to newer or well-kept homes. Neither covers flood, earthquake, wear and tear or maintenance problems.
If you own a house, odds are your policy is an HO-3, the form the Insurance Information Institute describes as the most common type of homeowners policy. An HO-5 is the step up. The names sound technical, but the difference comes down to one question: when something you own is damaged, who has to prove what caused it, and does the cause have to be on a list?
This article compares the two forms side by side, lists the named perils that limit an HO-3, explains who should consider an HO-5 and shows how to find your form on your policy. For the full picture of coverages, deductibles, exclusions and claims, see our homeowners insurance guide.

HO-3 vs. HO-5 at a Glance
| Feature | HO-3 (special form) | HO-5 (comprehensive form) |
|---|---|---|
| Dwelling (Coverage A) | Open perils | Open perils |
| Other structures (Coverage B) | Open perils | Open perils |
| Personal property (Coverage C) | Named perils only | Open perils |
| Who proves the cause on contents claims | You show a listed peril caused it | Insurer must show an exclusion applies |
| Typical cost | Lower | Higher |
| Typical eligibility | Most owner-occupied homes | Often newer or well-maintained homes |
| Flood, earthquake, wear and tear | Excluded | Excluded |
Both forms include the same six coverage parts, from the dwelling through medical payments to others. Our explainer on homeowners Coverages A through F describes each part in detail.
Open Perils vs. Named Perils, in Plain English
Insurance policies describe causes of damage as perils. There are two ways to write coverage for them.
Named perils
A named-perils policy lists the causes it covers. If the damage came from something on the list, the claim moves forward. If the cause is not listed, there is no coverage, no matter how sudden or accidental the event was.
Open perils
An open-perils policy covers direct physical loss from any cause unless the policy excludes it. You do not have to match the event to a list. To deny the claim, the insurer has to point to an exclusion in the policy.
That shift in who carries the burden is why open-perils coverage is considered broader. It also explains why the same accident can be covered under one form and denied under the other.
The 16 Named Perils That Limit an HO-3
Under the standard ISO HO-3 form, personal property is covered for these named perils:
- Fire or lightning
- Windstorm or hail
- Explosion
- Riot or civil commotion
- Aircraft
- Vehicles
- Smoke
- Vandalism or malicious mischief
- Theft
- 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 and accidental tearing apart, cracking, burning or bulging of a heating, air conditioning, sprinkler or water heating system
- Freezing of plumbing, heating, air conditioning or sprinkler systems or household appliances
- Sudden and accidental damage from artificially generated electrical current
- Volcanic eruption
Each peril carries conditions in the policy. Windstorm coverage for property inside the home, for example, generally applies only if wind or hail first creates an opening in the roof or a wall. Theft has its own special dollar limits for categories such as jewelry and firearms.
What falls outside the list
Plenty of common accidents are not on the list. Knocking a television off its stand, spilling coffee on a laptop, dropping a camera or staining an expensive rug are not named perils, so an HO-3 generally would not pay for them. Under an HO-5, the same events may be covered, because accidental damage is not excluded in the standard form, subject to your deductible and any special limits.
What HO-5 Adds and What It Does Not
An HO-5 extends open-perils coverage to your belongings. That is the main difference, and for many households it is the only one that matters.
Common extras insurers pair with HO-5
Insurers often package HO-5 policies with features that may be optional on an HO-3, such as replacement cost settlement for personal property or higher special limits for certain valuables. These are company choices, not part of the definition of the form, so compare the actual declarations pages rather than assuming.
What stays excluded
Moving to an HO-5 does not remove the major exclusions shared by both forms:
- Flood, including storm surge and overflow of bodies of water
- Earthquake and other earth movement
- Wear and tear, deterioration, rust, rot and mold (except limited mold coverage tied to a covered water loss)
- Damage from insects, rodents, birds and other animals owned or kept by you, plus vermin
- Water backup through sewers or drains, unless you add an endorsement
- Neglect and intentional loss
- Ordinance or law costs above any small built-in amount
Losses from these causes need separate policies or endorsements, regardless of form.
Deductibles and limits still apply
An HO-5 is not a promise to pay any loss in full. Your deductible, any percentage wind or hurricane deductible and the policy limits all still apply. Our article on the difference between a deductible and a premium explains how those choices affect what you pay and what you collect.
Example Claims Under Each Form
These short scenarios show how the forms can lead to different results. They assume no special exclusions or endorsements apply and that the loss exceeds the deductible.
| Event | HO-3 result for belongings | HO-5 result for belongings |
|---|---|---|
| Kitchen fire damages furniture | Covered (fire) | Covered |
| Burst pipe soaks a sofa | Generally covered (accidental discharge of water) | Covered |
| Child knocks a TV off a stand | Generally not covered (not a named peril) | Generally covered |
| Paint spill ruins a rug | Generally not covered | Generally covered |
| Basement floods during heavy rain | Not covered (flood exclusion) | Not covered |
| Sofa worn out by years of use | Not covered (wear and tear) | Not covered |
The dwelling itself is covered on an open-perils basis under both forms, so a paint spill on a hardwood floor, for example, is evaluated the same way under either form.
Special Limits Apply Under Both Forms
Open-perils coverage does not mean unlimited coverage for every item. Both standard forms set special limits of liability for certain kinds of property, usually listed in the personal property section of the policy. Typical categories include cash and coins, securities and documents, watercraft and trailers, jewelry, watches and furs (often for theft only), firearms, silverware and goldware, and business property kept at home.
These caps apply per loss, and they are often far below what a family’s jewelry box or collection is actually worth. An HO-5 does not raise them on its own, although some insurers include higher amounts in their HO-5 packages. The usual fix is to schedule valuable items individually with an appraisal or receipt, which gives each one its own limit and often removes the deductible for that item. If you own anything you would be upset to lose that falls into one of these categories, list it and ask your insurer how it would be covered under the form you are considering.
Who Should Consider an HO-5?
An HO-5 is worth pricing if one or more of these describe you:
- You own many valuable belongings such as electronics, furniture, instruments or collections, and would struggle to replace them after an accident.
- You want simpler claims where the insurer must cite an exclusion to deny coverage.
- Your home is newer or recently updated, which may make you eligible at a reasonable price.
- You have children or pets and accidental damage is a realistic risk.
An HO-3 may be enough if your belongings are modest, you are comfortable absorbing small accidental losses, or the HO-5 premium difference is large compared with what you would gain.
Eligibility limits
Not every home qualifies. Insurers commonly restrict HO-5 to homes below a certain age, homes with updated roofs, wiring and plumbing, or homes above a minimum value. Availability also varies by state and company.
A middle option: endorse the HO-3
Many insurers sell an endorsement that converts HO-3 personal property coverage to an open-perils basis, which can produce coverage close to an HO-5 without changing forms. Under the ISO program, this is the special personal property coverage endorsement. Ask whether your insurer offers it and compare the cost with a full HO-5.
How to Tell Which Form You Have
The form name is on your paperwork, though it is not always obvious.
- Check the declarations page. Look for a “policy form” line or a list of forms and endorsements. ISO-based forms are often printed as HO 00 03 or HO 00 05, sometimes with a date.
- Read the personal property section. If Coverage C says it covers “direct physical loss caused by” a list of perils, it is named perils. If it covers “direct physical loss” unless excluded, it is open perils.
- Look for marketing names. Some insurers give their policies brand names that do not mention the form. The coverage wording is what counts.
- Ask your agent or insurer in writing if you cannot tell. Request the form number and any endorsements that change personal property coverage.
Renters and condo owners
If you rent, your policy is likely an HO-4, which covers belongings on a named-perils basis by default. Our article on what renters insurance covers explains that form. Condo owners usually have an HO-6, which can also be broadened with endorsements.
Questions to Ask When Comparing Quotes
When you request HO-3 and HO-5 quotes, use the same limits and deductibles so the price difference reflects the form. Then ask:
- Is personal property settled at replacement cost or actual cash value?
- What are the special limits for jewelry, watches, firearms, silverware, cash and electronics?
- Does the quote include water backup, ordinance or law, or equipment breakdown coverage?
- Is there a separate wind, hail or hurricane deductible, and what is it in dollars?
- How is the roof settled, at replacement cost or on a depreciation or payment schedule?
- Is an open-perils personal property endorsement available for the HO-3?
Water losses deserve extra attention
Water is behind many home claims and many disputes. Both forms treat sudden plumbing leaks similarly, while flooding and sewer backup are excluded from both without extra coverage. Our guide on getting insurance to pay for water damage explains how those claims are handled.
Frequently Asked Questions
Is HO-5 better than HO-3?
HO-5 is broader because it covers personal property on an open-perils basis, but it usually costs more. It is better coverage, not automatically a better value. Compare the price difference with what you would gain for your belongings.
Does an HO-3 cover accidental damage to my belongings?
Generally only if the accident falls under one of the named perils, such as fire, theft or accidental discharge of water. Drops, spills and breakage are generally not named perils.
Does HO-5 cover flood damage?
No. Flood is excluded from both HO-3 and HO-5 policies. You need a separate flood policy through the National Flood Insurance Program or a private flood insurer.
Can I switch from HO-3 to HO-5 at renewal?
Often, if your home meets the insurer’s eligibility rules. Ask for an HO-5 quote before renewal, or ask whether an endorsement can broaden personal property coverage on your current HO-3.
What is the difference between HO-2 and HO-3?
An HO-2 covers both the dwelling and personal property on a named-perils basis. An HO-3 covers the dwelling on an open-perils basis and personal property on a named-perils basis.
The Bottom Line
HO-3 and HO-5 protect your house the same way. The difference is your belongings: named perils under HO-3, open perils under HO-5. If accidental damage to your belongings would hurt your budget, price an HO-5 or an open-perils endorsement on your HO-3, and compare quotes with identical limits, deductibles and settlement terms.
