Homeowners policies are usually built on one of three coverage forms, and the form determines what’s actually covered when something goes wrong. Special form (also called open peril, and typically labeled HO-3 or HO-5) covers everything except what’s specifically excluded. Broad form (HO-2) and basic form (closer to a DP-1 dwelling policy) only cover the specific causes of damage, called perils, that are written into the policy. If your loss isn’t on the list, there’s no claim.
This one distinction affects more homeowners than almost anything else in a policy, and most people never hear it explained until they’re standing in a damaged living room asking why their claim was denied.
Quick Answers to Common Questions
What’s the difference between named peril and open peril coverage? Named peril coverage (basic and broad forms) only pays for damage caused by perils specifically listed in the policy. Open peril coverage (special form) pays for damage from any cause except the ones specifically excluded.
Which form do most homeowners have? It depends entirely on which company wrote the policy and how it was sold. Many captive agents, meaning agents who represent one insurance company, and direct writers, meaning companies you buy from over the phone or online without an agent, default to named peril forms. Homeowners often don’t realize this because nobody walked them through it.
Which form does Curabba Agency use? We build policies on the special (open peril) form whenever the home qualifies. It’s the strongest protection available and it closes the door on most of the “I didn’t know that wasn’t covered” conversations that happen after a loss.
Why would anyone use a named peril form? Sometimes the condition of the home requires it. Certain carriers restrict older roofs, aging electrical or plumbing systems, or other risk factors to a named peril form as a condition of writing the policy. That’s an underwriting decision the carrier makes based on the risk, not a coverage choice we’d make by preference.
Basic Form: The Shortest List
Basic form is the narrowest of the three. It only covers a short, specific list of perils, typically things like fire, lightning, windstorm, hail, explosion, and a handful of others. If the cause of your damage isn’t on that list, the claim is denied, no matter how much damage occurred or how unfair it feels. We see this play out every winter in the Hudson Valley.
Claims example: A heavy, wet snowfall builds up on a garage roof over several days, and the added weight causes the roof to collapse. That’s not fire, lightning, or any of the other perils on the basic form list. Basic form has no peril for the weight of ice, snow, or sleet, so the collapse isn’t covered, even though it’s one of the most common winter claims we see.
Claims example: A supply line freezes and bursts during a hard cold snap, flooding a bathroom below. Basic form doesn’t include a freezing peril at all, so this claim is denied outright, regardless of whether the homeowner kept the heat running or not.
We rarely place a policy on basic form. It comes up in extreme cases, generally when a home’s condition is poor enough that even carriers who write named peril policies won’t take it any other way. It’s not the norm, and it’s not something we reach for unless there’s no better option available.
Broad Form: A Longer List, Still a List
Broad form covers more perils than basic form. It typically adds things like the weight of ice and snow, falling objects, freezing pipes, and accidental discharge of water from plumbing. That sounds close to complete coverage, and that’s exactly where the confusion starts.
Broad form is still a named peril form. Everything still has to match something on the list, and the list often comes with conditions attached. Freezing pipe coverage, for example, usually requires that you kept the heat on or shut the water off and drained the pipes while the home was unoccupied. Miss that condition and the coverage that looked like it applied doesn’t.
Claims example: During a cold snap, heat escaping from the attic melts the snow on the upper part of the roof. That water runs down and refreezes at the colder eaves, forming an ice dam. Water backs up underneath the shingles, which are otherwise perfectly intact, no wind damage, no missing shingles, and works its way into the ceiling and down an interior wall. Broad form’s peril list includes coverage for damage caused by the weight of ice and snow, but that peril is about structural weight, like a roof collapsing under a heavy snow load. It isn’t written to cover water intrusion from an ice dam, since the roof itself was never physically damaged. Under a strict reading of broad form, that water damage falls outside the named list and the claim can be denied.
We use broad form when the condition of the home requires it. This usually happens with older homes where a roof, electrical panel, or plumbing system doesn’t meet a carrier’s requirements for the open peril form, but the home is otherwise insurable. It’s a middle ground, not our first choice.
Special Form (Open Peril): Coverage Unless Excluded
Special form flips the structure entirely. Instead of listing what’s covered, the policy lists what’s excluded, things like flood, earthquake, and a small number of other specific exclusions. Everything else is covered. The burden shifts from you having to prove your loss matches a listed peril, to the insurance company having to prove your loss matches a listed exclusion.
Claims example: Using the same ice dam scenario from above, that water intrusion under an intact roof is a covered claim under special form. It wasn’t caused by flood, earthquake, or any of the specific exclusions in the policy, so it’s covered even though there’s no peril on any list that specifically says “water backing up under an ice dam.” Same roof, same water, same winter, completely different outcome depending on the form the policy was built on.
This is why we default to special form whenever the home qualifies. It’s the strongest form available and it removes most of the guesswork about what will and won’t be covered when something unexpected happens.
One Loss, Three Different Outcomes
Several days of heavy rain leave the ground completely saturated. The root system of a large tree on the property fails under its own weight in the soft, waterlogged soil, and the tree topples over and crushes the corner of the garage roof. No wind, no storm, nothing driving it beyond gravity and soaked ground.
Under basic form: Denied. There’s no wind, no lightning, no fire, nothing on the short basic peril list that matches saturated ground causing a tree to fall on its own. Basic form isn’t written to cover falling objects at all, storm-driven or otherwise.
Under broad form: Covered. Falling objects is a named peril on the broad form list, and it isn’t conditioned on wind or weather being involved. The tree striking the garage matches a peril on the list, so the claim is paid.
Under special form: Covered. Same result as broad form here, since a falling tree isn’t one of special form’s exclusions either.
This example is useful because it shows broad form isn’t always the weak link. When the cause of loss happens to match something on its list, broad form pays just like special form does. The real risk with named peril forms isn’t that they deny everything, it’s that coverage depends entirely on whether your specific loss happens to match specific wording, and you often don’t find out whether it matches until after the damage is done.
Why This Matters When You’re Comparing Quotes
Two homeowners policies can look nearly identical on a quote sheet. Same dwelling limit, same liability limit, similar premium. But if one is written on special form and the other on broad or basic form, they are not the same product, and the difference only shows up at claim time, which is the worst possible moment to discover it.
Many captive agents and direct writers sell named peril policies as standard practice, and the coverage form often isn’t something that gets explained during the sales conversation. That’s not a knock on those companies. It’s simply how their products are typically structured. When we quote a home, we always tell you which form the policy is built on and why, so you’re never finding out the hard way.
