3.1 Dwelling Policy Overview
Key Takeaways
- The ISO dwelling program (DP forms) insures residential property that is NOT owner-occupied as a primary residence — rentals, seasonal homes, and dwellings ineligible for a homeowners policy
- Unlike a homeowners policy, the base DP form provides NO personal liability and NO medical payments — it is property-only unless liability is added by endorsement
- The three ISO forms are DP 00 01 (Basic), DP 00 02 (Broad), and DP 00 03 (Special), with coverage and premium increasing across the series
- Eligibility generally allows up to four families and up to five roomers/boarders per family; certain incidental business occupancies are permitted
- Dwelling coverage is keyed to the described location and the named insured's interest, not to the family unit the way a homeowners policy is
What Is a Dwelling Policy?
A dwelling policy is property insurance for one- to four-family residential buildings written on an Insurance Services Office (ISO) dwelling form. The program is designed for risks that do not fit the owner-occupied homeowners (HO) program. The dwelling forms are sometimes called "dwelling fire" policies because the basic form historically grew out of the standard fire policy.
Typical uses tested on the exam:
- Rental dwellings owned by a landlord who does not live there
- Seasonal or secondary residences (vacation homes, lake cabins)
- Dwellings under renovation or that fail HO underwriting (older homes, poor protection class)
- Tenant-occupied single-family homes and small multi-family buildings (up to four units)
Eligibility Rules
The ISO dwelling program has specific eligibility limits candidates are expected to recognize:
| Eligibility Item | Rule |
|---|---|
| Number of families | No more than four families in the dwelling |
| Roomers/boarders | No more than five per family |
| Incidental occupancies | Limited business use (e.g., a home office or one studio/office) is permitted |
| Owner vs. tenant | May be owner-occupied or tenant-occupied; the HO program is reserved for owner-occupants |
Exam trap: A four-plex is eligible for a DP form; a six-unit building is not — it would move to a commercial or specialty program.
Dwelling Policy vs. Homeowners Policy
The single most tested distinction is that the base dwelling form covers property only — there is no built-in liability or medical payments. Liability can be added with the Personal Liability Supplement or a separate liability policy.
| Feature | Dwelling (DP) Policy | Homeowners (HO) Policy |
|---|---|---|
| Primary use | Rentals, seasonal, non-qualifying | Owner-occupied primary residence |
| Personal liability (Coverage L) | NOT included (add by endorsement) | Included |
| Medical payments to others (Coverage M) | NOT included | Included |
| Personal property | Optional (Coverage C) | Automatically included |
| Loss of use to landlord | Fair Rental Value | Additional Living Expense |
| Theft on basic form | DP-1 has no theft; HO forms include it | Included |
Coverage Lettering
Dwelling forms use letter designations that differ from homeowners letters — a frequent point of confusion:
| Coverage | Dwelling Form |
|---|---|
| A | Dwelling |
| B | Other Structures |
| C | Personal Property (optional) |
| D | Fair Rental Value |
| E | Additional Living Expense |
Note that on the dwelling form, liability is Coverage L and medical payments is Coverage M — and both are added separately, not part of A–E.
Worked Example
A landlord owns a $250,000 three-unit rental and lives elsewhere. She needs:
- Coverage A for the building
- Coverage D – Fair Rental Value to replace lost rent if a fire makes units uninhabitable
- A small Coverage C limit for her own coin-operated laundry equipment and a refrigerator she supplies
- A separate liability policy or the Personal Liability Supplement, because a tenant who slips on the stairs would otherwise have no coverage under the DP form
Her tenants, in turn, need their own HO-4 renters policies for their belongings and liability — the landlord's DP policy protects neither.
Industry Context
The dwelling line is a meaningful share of the residential market and has grown with single-family rentals and short-term rental platforms. Short-term rental (Airbnb/VRBO) exposures usually require an endorsement or a specialty program because the base DP form contemplates conventional long-term occupancy, not transient guests. Always read the exam question for clues — "landlord," "vacant," "seasonal," or "not occupied by the owner" all point toward a DP form rather than an HO form.
How the Dwelling Program Differs From the Homeowners Program in Structure
Beyond the liability gap, the dwelling program is built differently from the homeowners program in three ways the exam likes to probe:
- No mandatory contents. A homeowners policy bundles Coverage C automatically (typically 50% of Coverage A). The dwelling form leaves contents optional, so a landlord with an empty rental can buy building-only coverage and pay no contents premium.
- Loss of use is split by role. The homeowners form gives one Coverage D that flexes between Fair Rental Value and Additional Living Expense. The dwelling form names them separately — Coverage D (Fair Rental Value) for the landlord and Coverage E (Additional Living Expense) for an owner-occupant.
- Perils are added in layers on DP-1. Where the HO forms come pre-loaded with broad perils, the DP-1 starts at fire/lightning/internal explosion and lets the buyer bolt on Extended Coverage and Vandalism & Malicious Mischief. This modular design is why DP-1 is the cheapest entry point for a bare structure.
Insurable Interest and the Described Location
Like all property insurance, a dwelling policy requires the insured to have an insurable interest — a financial stake that would suffer if the property were damaged. The policy attaches to a described location shown on the Declarations, not to wherever the insured happens to be. If the landlord sells the building, coverage does not automatically follow to a new property; a new policy or endorsement is required. This "follows the property, at a fixed location" character is the practical reason landlords with multiple rentals schedule each address separately rather than relying on a single floating policy.

| Owner rents it out / lives elsewhere? | Lean DP program |
| More than four families? | Out of the DP program |
