4.1 Homeowners Forms HO-2 through HO-8 and Eligibility

The ISO Homeowners Program

The homeowners (HO) policy is the most heavily tested topic in the property half of the Property & Casualty (P&C) exam. The Insurance Services Office (ISO) publishes standardized forms identified by number. Each is a package policy that bundles first-party property insurance (Section I) with third-party liability insurance (Section II) under one premium and one expiration date.

The exam tests two facts about every form: who it is written for, and the peril basis that triggers coverage.

Open Perils vs. Named Perils

This distinction decides who must prove a disputed claim:

• Named perils (also called specified or broad perils): the loss is covered only if its cause appears on a list. The insured must prove the cause is a listed peril.
• Open perils (also called special or all-risk): every cause of loss is covered unless specifically excluded. The insurer must prove an exclusion applies to deny the claim.

Exam tip: Open-peril coverage is broader and more expensive precisely because it flips the burden of proof onto the insurer.

The Current HO Forms at a Glance

Trap: HO-1 (Basic Form) is obsolete in nearly every state. If it appears as a choice, it is almost always a distractor.

HO-3 — The Workhorse

Any question that says "most common," "standard," or "typical" owner-occupied home points to HO-3 (Special Form). It writes the dwelling (Coverage A) and other structures (Coverage B) on an open-peril basis while keeping personal property (Coverage C) on a named-peril basis. This split delivers broad structural protection at a lower premium than HO-5.

HO-5 — Comprehensive

HO-5 upgrades contents to open perils too. If a single valuable item is damaged from an unknown cause, the insured no longer has to prove a listed peril; the insurer must prove an exclusion. HO-5 is the broadest unscheduled form and the most expensive.

HO-4 (Renters) and HO-6 (Condo)

These forms break the own-the-building rule:

• HO-4 covers a tenant's personal property and provides liability, but no building coverage — the landlord insures the structure.
• HO-6 covers a condo unit-owner's walls-in improvements (the interior the owner is responsible for), contents, liability, and loss assessment (the owner's share of a master-policy deductible or shortfall). The association's master policy insures the building exterior and common areas.

HO-2 and HO-8

HO-2 (Broad Form) writes the dwelling and contents on the same named-peril list — a budget choice. HO-8 (Modified Coverage Form) solves the problem of an older or historic home whose replacement cost (recreating hand-carved detail) far exceeds its market value. HO-8 settles losses on a functional replacement cost basis using modern equivalent materials, on a named-peril basis.

Trap: For an 1890s Victorian where rebuilding cost vastly exceeds market value, the answer is HO-8, not HO-3 or HO-5.

Eligibility Rules

An HO form requires all of the following:

1. Owner-occupancy — the named insured owns and lives in the dwelling as a residence.
2. One-to-four-family dwelling — five or more units require commercial property insurance.
3. Residential use — incidental home office allowed within sublimits; true commercial operations are not.
4. Insurable condition — functional heating, electrical, plumbing, and reasonable upkeep.

Trap: A landlord, rental, vacant, or seasonal risk almost always points to a Dwelling (DP) form, not an HO form.

How HO-3 and HO-5 Differ on an Actual Claim

Because the dwelling is open peril on both HO-3 and HO-5, the only practical difference is contents (Coverage C). Picture a homeowner whose expensive camera is found cracked with no known cause. Under HO-3 the insured must show a listed cause such as theft, vandalism, or a falling object; a mysterious crack with no listed peril is denied. Under HO-5 the insurer must instead prove an exclusion, so the same crack is generally paid. That single shift in burden of proof is why HO-5 commands a higher premium.

Condo and Mobile-Home Edge Cases

For an HO-6, the association's master policy can be written bare walls, single entity, or all-in, and that choice directly changes how much walls-in Coverage A the unit-owner must buy. A producer who reads the master-policy declarations can right-size the HO-6 building limit and the loss-assessment coverage. Manufactured (mobile) homes are not eligible for a standard HO-3; they use a mobile-home endorsement that adapts the homeowners form to a transportable dwelling. Both are common applied-knowledge questions on the exam.

Matching Form to Client - a Decision Guide

The practical skill the exam rewards is choosing the right form for the fact pattern. An owner-occupant of a single-family home almost always takes HO-3 (open peril on the dwelling, named peril on contents) or HO-5 (open peril on both) for the broadest protection. A budget-conscious or older home that cannot meet replacement-cost underwriting may land on HO-8 (modified, ACV/functional settlement). A renter takes HO-4 (contents and liability, no building). A condo or co-op unit owner takes HO-6, sized to the association master policy.

The disqualifiers are equally testable: non-owner-occupied rentals go to the Dwelling Property program, and manufactured homes need the mobile-home endorsement. A fact pattern naming the occupant and structure type usually points directly to one form.

Exam Tip: HO-3 (open dwelling/named contents) is the default owner form; HO-5 is broadest (open on both); HO-4 = renters; HO-6 = condo; HO-8 = older/modified ACV; the DP program covers non-owner-occupied dwellings the HO forms decline.
