HO-3 vs. HO-5

The HO-3 and HO-5 are two of the standard ISO homeowner policy forms. HO-3 is the most common — it covers the dwelling (Coverage A) for any peril not explicitly excluded, but covers personal property (Coverage C) only for the perils named in the policy (fire, theft, vandalism, certain water losses, etc.). HO-5 extends the open-perils coverage to personal property as well, which is why it’s sometimes called "comprehensive" coverage. HO-5 premiums are typically 10–25% higher than HO-3 for the same dwelling.

On a named-perils Coverage C, if your loss doesn’t fit one of the listed perils, it isn’t covered — even if the dwelling itself would have been covered under the same loss. Example: a child accidentally damages a high-end stereo. Under HO-3, accidental damage to contents isn’t a named peril (the dwelling form is open-perils, but contents isn’t), so the loss isn’t covered. Under HO-5, contents are open-perils, so the loss would be covered unless explicitly excluded. The upgrade is meaningful for homes with significant scheduled or unscheduled personal property.

A homeowner with a $400k dwelling, $200k contents, and significant electronics + scheduled jewelry is on an HO-3 paying $1,800/yr. The HO-5 quote is $2,100/yr — $300 more. After a year, a contractor working on a remodel accidentally drops a tool and shatters a $4,200 designer light fixture and a $1,800 sound bar. Under HO-3: contents not covered (accidental breakage isn’t a named peril). Under HO-5: covered minus deductible. The HO-5 paid for itself 14× in one claim.
