What is named-peril vs open-peril coverage?
Two contract structures govern home insurance: named-peril pays only for losses whose cause is on the policy's list, and open-peril pays for any cause of loss except those the policy specifically excludes. The burden of proof flips between them, the Insurance Information Institute notes (verified May 2026).
Under an open-peril policy the carrier bears the burden of proving a loss is excluded; under a named-peril policy the homeowner bears the burden of proving the cause is covered, United Policyholders explains in its consumer-side primers (verified May 2026). The practical example is a sudden interior water leak from a burst supply line. On an open-peril dwelling form the insurer must point to an exclusion to deny coverage; on a named-peril form the homeowner must show the cause matches a listed peril, or the claim doesn't trigger.
FAIR Plan base policies are typically named-peril, which is why this distinction surfaces most when an admitted carrier non-renews and a state-of-last-resort plan steps in.
How it works
Most U.S. home insurance is written on standardized forms drafted by the Insurance Services Office (ISO), the industry body whose model contract language carriers file with state regulators. The form number printed on your declarations page is how the named-peril or open-peril question gets fixed in writing.
The forms you will see most often:
- HO-3: the dwelling is open-peril; personal property is named-peril. This is the standard U.S. homeowner policy.
- HO-5: both the dwelling and personal property are open-peril. Broader, more expensive.
- HO-8: older homes that do not replace at modern building cost; named-peril.
- DP-1 (dwelling fire, basic): named-peril, a short list of covered causes. Most FAIR Plan base policies sit here.
- DP-3 (dwelling fire, special): open-peril dwelling, named-peril contents.
At claim time the burden of proof flips. With an open-peril policy, the carrier has to show the cause is excluded to deny the claim. Under a named-peril policy, you have to show the cause is on the covered list. That is the practical reason a FAIR Plan offer alone, with no difference-in-conditions wrap, is narrower than the HO-3 you had.
Why it matters
If you got a non-renewal notice and the only quote you can find is a FAIR Plan or surplus-lines policy, the named-peril versus open-peril distinction stops being theoretical. Your old open-peril policy covered any cause of loss except its listed exclusions; the replacement may cover only what's on a short list, and the gap is yours.
Where you live shapes the gap. In states with a FAIR Plan, the base policy is usually named-peril, and a difference-in-conditions wrap fills the missing perils. Without a plan, the fallback is the surplus-lines market: an open-peril dwelling form is sometimes available, often with steeper deductibles and more exclusions.
Situation matters too:
- Coastal vs inland: coastal homes often face wind or hurricane sublimits, or a separate windstorm policy, even on an open-peril form. Inland homes usually keep the open-peril breadth, and lose it on the FAIR Plan side.
- Owner-occupied vs investor/rental: dwelling forms sit alongside the homeowner line. DP-1 is named-peril; DP-3 is open-peril. A landlord switching from DP-3 to DP-1 to save premium gives up the broader form.
- Mortgaged vs free-and-clear: if your policy lapses, a lender can force-place coverage; the force-placed policy is almost always named-peril with the carrier as the loss payee.
To check your own situation, read the form designation on your declarations page (HO-3, HO-5, DP-1, DP-3, or FAIR Plan basic) and the perils-insured-against clause. The state Department of Insurance publishes a consumer guide to these forms; if the letter just landed, the non-renewal walkthrough picks up from there.
How to check what you've got
- Find your policy's declarations page and look for the form code. HO-3 and DP-3 are open-peril on the dwelling; HO-5 is open-peril throughout; HO-2 and DP-1 are named-peril. Most FAIR Plan base policies are named-peril.
- Read the exclusions, not just the inclusions. On an open-peril form, the exclusions section is where coverage ends. A named-peril form flips that: the covered-perils list is the ceiling; anything outside it is uncovered.
- Compare the gap to your actual risk. A named-peril FAIR Plan policy in a wildfire or coastal-wind zone usually leaves gaps a difference-in-conditions policy is designed to fill.
- Separately, ask how losses are valued. Whether the form pays replacement cost or actual cash value is independent of the peril question, but both shape what arrives after a claim.
- Call your state Department of Insurance consumer line before you call a broker. They can read your declarations page over the phone with no sales overlay. If you have just been non-renewed, see: what to do if you got a non-renewal notice.
Frequently asked questions
Is the California FAIR Plan written on a named-peril or open-peril basis?
The California FAIR Plan's base dwelling policy is named-peril, the California FAIR Plan Association states in its policy forms (verified May 2026). It covers fire, lightning, internal explosion, and the perils explicitly listed; other causes of loss require an endorsement or a separate wrap policy.
Does an HO-3 policy cover my personal property on an open-peril basis?
No. An HO-3 is open-peril on the dwelling and named-peril on personal property, the Insurance Information Institute notes (verified May 2026). Only an HO-5 form writes both the dwelling and personal property on an open-peril basis, which is one reason HO-5 carries a higher premium.
What is the difference between a DP-1 and a DP-3 dwelling form?
A DP-1 is the basic dwelling form, written on a named-peril basis with a short list of covered causes of loss. A DP-3 is the special dwelling form, written on an open-peril basis with broader coverage and a higher premium, the Insurance Information Institute notes (verified May 2026).
How do I tell whether my policy is named-peril or open-peril?
Check the form number on your declarations page: HO-3 and HO-5 are the standard open-peril homeowner forms drafted by the Insurance Services Office (ISO); HO-8, DP-1, and most FAIR Plan base policies are named-peril. On an HO-3 the dwelling is open-peril but personal property is still named-peril.
Why does the difference between named-peril and open-peril matter at claim time?
The burden of proof flips. Under an open-peril policy the carrier has to prove the cause of loss is excluded; under a named-peril policy you have to prove the cause is on the covered list, which is why a FAIR Plan DP-1 alone is narrower than the HO-3 it replaces.
If my state has no FAIR Plan, do I get an open-peril policy by default?
Not automatically. In the no-plan states the fallback is the surplus-lines market; an open-peril dwelling form is sometimes available, often with higher deductibles, more exclusions, and a windstorm sublimit. Ask a broker who writes surplus-lines.
Is force-placed insurance named-peril or open-peril?
Force-placed insurance is almost always named-peril and written with the lender as loss payee, not you. It is normally significantly more expensive than voluntary coverage, and removing it requires showing the lender proof of a replacement policy.
Is open-peril always better than named-peril?
Generally yes for breadth, but it costs more and the exclusions still matter. The form is only useful if it covers the perils your address actually faces.
What's the most common form on a standard homeowner's policy?
HO-3 is the most common: open-peril on the dwelling, named-peril on personal property. HO-5 covers both on an open-peril basis but is rarer and pricier.
