Why it's called the "special form"
The classic homeowners forms come in three flavors of breadth: basic, broad, and special. The HO-3 is the special form — the broadest of the standard set — and its signature move is a split personality. Your dwelling and other structures are covered open-perils: any cause of loss is covered unless the policy specifically excludes it. Your personal property is covered named-perils: only the causes of loss on the policy's list (roughly sixteen of them) are covered.
That asymmetry is a price/protection compromise, and it's the single most useful thing to know about your policy. When the house is damaged, the carrier must point to an exclusion to deny. When your belongings are damaged, you must fit the claim onto the list. The full anatomy of the gap lives here: open perils vs named perils, with examples.
The six coverages inside every HO-3
Every HO-3 is built from the same six parts — Coverages A through F. Coverage A rebuilds the house; B covers detached structures at typically 10% of A; C covers your belongings at 50–70% of A; D pays your living expenses while displaced (20–30% of A, or a time limit); E defends and pays liability claims at $100k/$300k/$500k options; F pays guests' small medical bills no-fault at $1k–$5k. Each has its own deep dive on this site, starting with Coverage A — the number everything else scales from.
How to read your dec page in ninety seconds
The declarations page is the policy's cover sheet, and it's where placements go right or wrong. Read it top to bottom:
| Line | What to check |
|---|---|
| Named insured | Everyone on title (trusts and LLCs need a conversation with your broker) |
| Coverage A | Tracks current rebuild cost — not your Zillow estimate. The method |
| Deductible | Flat dollar vs percentage; wildfire/wind deductibles hide here. Choosing one |
| Endorsements | Extended replacement cost, ordinance/law, water backup, scheduled items |
| Settlement basis | RCV vs ACV — especially for the roof. Why it matters |
The two exclusions that define California
No HO-3 covers earthquake or flood — both take separate policies. Wildfire, on the other hand, IS covered: fire is a core peril on every HO-3 and even on the FAIR Plan. California's wildfire problem is carrier appetite, not policy language. The wildfire reality →
A short history, and why the form persists
The HO forms were standardized in the mid-twentieth century to replace a patchwork of fire policies with bolted-on riders. The HO-3 won because its compromise matched how losses actually happen: catastrophic damage tends to hit the structure (where coverage is broadest), while contents losses are usually fire, theft, or water — all named perils anyway. Carriers have refined the edges since, but a 1970s adjuster would recognize today's form.

It fits the owner-occupied house or roof-to-foundation townhouse with a normal risk profile — which is most of California. Look at the HO-5 if your contents are substantial or you simply want the burden of proof on the carrier for everything you own: open-perils contents at replacement cost, typically 10–20% more premium. That's the specialty of our sister site BestHO5.com, and the comparison lives at HO-3 vs HO-5. Renters take an HO-4. Condo owners take an HO-6 that meshes with the HOA master policy. Landlords take a DP-3 — putting a rental on an HO-3 misstates the occupancy and can void claims.
Frequently asked
Is an HO-3 the same from every carrier?
The skeleton is standardized; the flesh isn't. Carriers add their own endorsements, sub-limits, roof settlement schedules, and deductible structures — which is why identical homes are routinely priced 20–40% apart and why quotes deserve a line-by-line comparison, not a bottom-line glance.

Does an HO-3 cover my home-based business?
Only incidentally — small equipment sub-limits, no business liability. If clients visit or inventory lives at home, you need an endorsement or separate policy. Home business coverage →
What does "all-risk" mean? Is that an HO-3?
"All-risk" is older jargon for open perils, and it was never literally true — exclusions always apply. On an HO-3 it describes the dwelling coverage only; on an HO-5 it describes contents too.
