Most homeowners have an HO-3 policy and couldn’t tell you what that means. Not because they’re careless, but because no one ever explained it clearly. I’ll fix that.
The HO-3 is the standard homeowner policy sold across the United States. If you bought your home with a mortgage, your lender almost certainly required one. It’s the industry default, which sounds like a compliment. Sometimes it is. Sometimes it just means you have exactly as much coverage as your insurer was legally required to offer, not a dollar more.
When I talk to people signing their first policy, I always tell them this: ignore the number on the front page. What matters is how the policy covers your home versus your belongings, because the HO-3 treats them completely differently. That gap has real consequences when something actually breaks.
This table shows how the same damage event can result in different coverage outcomes depending on whether it affects your dwelling (open perils) or your belongings (named perils).
| Damage Scenario | Dwelling Coverage (Open Perils) | Personal Property Coverage (Named Perils) | Why the Difference |
|---|---|---|---|
| Tree falls on roof during storm | ✓ Covered | ✓ Covered (windstorm is named) | Windstorm appears on named perils list |
| Pipe bursts, floods basement | ✓ Covered | ✓ Covered (water damage from plumbing is named) | Sudden water discharge is a named peril |
| Freezer fails, food spoils | ✓ Floor damage covered | ✗ Food/appliance likely not covered | Mechanical breakdown and power failure aren't named perils |
| Mysterious water stain appears on ceiling | ✓ Covered (unless excluded) | N/A | Open perils covers unknown causes; exclusions would need to apply |
| Theft of electronics | ✓ Forced entry damage covered | ✓ Covered | Theft is a named peril |
| Your dog destroys the couch | ✓ Damaged flooring covered | ✗ Couch not covered | Pet damage to belongings isn't a named peril |
| Earthquake cracks foundation and breaks dishes | ✗ Not covered (standard exclusion) | ✗ Not covered | Earthquake is excluded from dwelling coverage and not a named peril |
General information for comparison, confirm specifics for your situation.
Open Perils vs. Named Perils: The Core Distinction
Your home itself, the structure, the attached garage, the built-in cabinets, is covered on what’s called an “open perils” or “all-risk” basis. This means the policy covers any cause of damage unless it’s explicitly excluded. Fire, wind, a falling tree limb, a car driving through your living room wall. All covered, because nothing in the policy rules them out.
Your personal property (furniture, clothing, electronics, appliances) works the opposite way. It’s covered on a “named perils” basis. The policy lists exactly what it will pay for: fire, theft, vandalism, windstorm, and roughly a dozen other events. If something damages your stuff and that cause isn’t on the list, you don’t have a claim.
I watched this happen repeatedly. A homeowner’s chest freezer fails while they’re vacationing. They come home to $800 in ruined food and a waterlogged basement. The floor gets covered under dwelling coverage. The food? Almost certainly not, because power outage isn’t a named peril for personal property. Same with the freezer itself, mechanical breakdown isn’t on the list.
This isn’t exactly a flaw in the HO-3. It’s a design choice. But you should walk into your policy knowing it.
What the HO-3 Actually Covers (And What It Doesn’t)

The policy breaks into several coverage components, each with its own limit and its own rules.
Dwelling coverage (Coverage A) pays to repair or rebuild your home’s structure. The number that matters here isn’t your purchase price or current market value. It’s replacement cost: what it would actually cost to rebuild from scratch at current labor and material prices. In 2026, with construction costs still elevated across most markets, a surprising number of homeowners are significantly underinsured without knowing it.
Other structures (Coverage B) covers detached garages, fences, sheds. It’s automatically set at 10% of your dwelling coverage. For most people that works fine. But if you have a detached workshop you’ve invested real money into, verify that 10% actually covers it.
Personal property (Coverage C) gets complicated fast. Most policies set this at 50% to 70% of your dwelling coverage, which feels substantial until you actually count everything you own. Jewelry, electronics, and collectibles often have sub-limits buried in the fine print, sometimes as low as $1,500 for jewelry theft. If you own anything valuable in those categories, you need a separate scheduled endorsement.
Loss of use (Coverage D) pays additional living expenses if your home becomes unlivable after a covered loss. Hotel bills, restaurant meals beyond your usual spending, temporary rental costs. This one rescues people financially after major losses and hardly anyone thinks about it when buying the policy.
Liability (Coverage E) and medical payments (Coverage F) cover you if someone is injured on your property or you accidentally damage someone else’s. Standard liability limits often max out at $100,000, which strikes me as too low for most homeowners today. Umbrella policies exist for this reason.
Now the exclusions: flood and earthquake. Neither is covered under any standard HO-3. Not partially, not at all. Zero coverage. These require completely separate policies, and the confusion costs homeowners serious money every year.
Replacement Cost vs. Actual Cash Value
This is where I see the most claim disappointment. It comes down to one word: depreciation.
Replacement cost coverage pays what it costs to replace a damaged item with something equivalent today. Actual cash value (ACV) pays that minus depreciation. Your 8-year-old roof gets destroyed in a hailstorm. With ACV, the adjuster might pay you 40% of a new roof’s cost because they calculated that a 20-year roof with 8 years of use has 60% depreciation built in. You cover the rest.
Most HO-3 policies cover your home’s structure at replacement cost. Contents are different. Some policies default to ACV unless you explicitly upgrade. Look at your declarations page for the phrase “replacement cost contents” or “RC contents.” If it’s not there, ask.
The IBHS home fortification guides focus mainly on mitigation, but they explain how construction quality affects replacement cost calculations. Useful if you’re questioning whether your Coverage A limit is realistic.
How to Actually Read Your Policy
Pull out your declarations page. That’s the summary sheet, usually one or two pages, with your coverage limits, deductibles, and premium. It’s not your full policy (which runs 40 pages) but it’s what matters right now.
Your declarations page shows you:
- Coverage A limit (dwelling coverage)
- Your deductible (and whether you have a separate, higher one for wind or hail)
- Whether personal property coverage is replacement cost or ACV
- Any endorsements you’ve added
Wind and hail deductibles are increasingly common in coastal and tornado-prone areas. They’re often percentage-based instead of a flat dollar amount. A “2% deductible” on a $400,000 home means you pay the first $8,000 of any wind or hail claim. That catches people off guard.
The NAIC publishes a free homeowner insurance shopping guide that explains how to compare terms across insurers. It’s dry but accurate, with a glossary that actually helps decode jargon.
Each year at renewal, spend 15 minutes checking whether your dwelling limit still matches current rebuild costs. Do a basic home inventory (apps like Encircle work, or just back up photos to the cloud) and confirm your personal property limit still fits. Store those records outside your home, ideally in a fireproof safe like the SentrySafe SFW123GDC or a secure cloud folder. (This site may earn a commission on product links.)
One more thing: install a water leak sensor near your water heater and under sinks. Water damage is one of the most common homeowner claims, and catching a slow leak early keeps it from becoming a six-figure disaster.
