3.4 Mobile Home and Specialized Dwelling Coverage
Key Takeaways
- Mobile homes are insured by adding the Mobilehome endorsement to an HO-2/HO-3 or a DP form; the structure settles at ACV unless RC is endorsed.
- The endorsement adds transportation/removal expense (commonly up to $500) to move the home away from an imminent covered peril.
- Seasonal dwellings use DP forms; the vacancy condition can suspend perils after 60+ consecutive days vacant.
- Condo unit-owners use the HO-6; FAIR Plans are last-resort named-peril coverage for high-risk dwellings.
- Flood is excluded by all dwelling and FAIR Plan forms and must come from the NFIP or private flood market.
Mobile Homes and Specialized Dwelling Coverage
Manufactured (mobile) homes and certain specialized residential risks need coverage the standard DP and HO programs do not fully provide. ISO addresses mobile homes through endorsements that attach to a base policy, and addresses other special exposures (condo units, seasonal dwellings, FAIR Plans) through purpose-built programs.
The Mobile Home endorsement
A mobile home is insured by adding the Mobilehome endorsement to either a Homeowners HO-2 or HO-3 (for owner-occupants seeking full HO Section I and II) or to a Dwelling DP form (for rental or limited needs). The endorsement modifies Coverage A to fit a manufactured home and adds mobile-home-specific Other Coverages. Eligibility generally requires the unit to be at least a stated size (commonly 12 feet wide and about 40 feet long, roughly 320+ sq ft) and designed for year-round living.
Mobile-home-specific coverages
- Coverage A insures the manufactured home itself, settled on an ACV basis unless a replacement cost endorsement is added (mobile homes depreciate, so ACV is the default and a frequent exam point).
- Transportation / Removal Coverage — pays the reasonable cost (commonly up to $500, or a stated higher limit) to move the home to avoid an imminent covered peril (e.g., an approaching wildfire or flood) and to return it.
- Property Removed while in transit, and coverage for permanently installed items.
| Feature | Standard DP/HO | Mobile Home endorsement |
|---|---|---|
| Default valuation on the structure | RC (HO/DP-3) | ACV unless RC endorsed |
| Removal-to-avoid-peril expense | Not provided | Up to $500 (or higher stated) |
| Eligibility | Site-built dwelling | Manufactured, year-round, min. size |
Other specialized dwelling programs
- Seasonal / secondary dwellings — written on a DP form (often DP-1 or DP-2) when the home is unoccupied for long stretches; the vacancy condition may suspend some perils (notably vandalism and water damage) after the dwelling is vacant beyond 60 consecutive days.
- Condominium unit-owners use the HO-6, which insures the unit's interior, improvements, and personal property above what the condo association's master policy covers; a related Unit-Owners dwelling approach exists for rented condos.
- FAIR Plans (Fair Access to Insurance Requirements) provide last-resort property coverage for dwellings in high-risk or distressed areas that the voluntary market declines; FAIR Plans typically write basic named-peril (fire/EC) coverage at ACV.
- National Flood Insurance Program (NFIP) writes the flood peril excluded by all dwelling forms, with separate Building and Contents limits and a standard waiting period.
Worked valuation example
A 5-year-old manufactured home has a replacement cost of $90,000 and an estimated ACV of $63,000 (30% depreciation). A covered fire is a total loss, and the policy has no replacement-cost endorsement.
- Settlement = ACV = $63,000 (less any deductible).
- Had the owner added the replacement cost endorsement and insured to value, settlement would be $90,000 (less deductible).
This $27,000 gap is the practical reason agents recommend the replacement-cost endorsement on newer manufactured homes — and why the default ACV basis is a common exam answer when no endorsement is mentioned.
Builders risk and dwellings under construction
A dwelling being built has a value that rises as work progresses, so two approaches exist. On the DP program, the Dwelling Under Construction endorsement (DP 11 43) charges an average rate over the construction period and insures to the completed value, with the amount payable limited to the value actually in place at the time of loss. On the commercial side, the same exposure is written as Builders Risk, often on a completed-value (reporting) basis that insures the finished value from day one and avoids coinsurance penalties as the structure grows.
Coverage triggers to remember: theft of building materials is generally excluded unless specifically added, and coverage typically ends when the building is occupied, accepted by the owner, or after a stated number of days — whichever comes first. Matching the correct construction approach to the risk is a recurring exam scenario.
Absent a replacement-cost endorsement, how does the Mobilehome program settle a covered total loss to the manufactured home itself?

Mobilehome Endorsement Mechanics and Valuation
The Mobilehome program attaches a Mobilehome endorsement to an HO-2 or HO-3, adapting it to a manufactured home. Coverage A insures the home itself; specialized add-ons cover transportation/permission to move (typically up to $500 or a stated limit for moving the home to avoid an impending peril) and property removal. Absent a replacement-cost endorsement, mobile homes often settle at ACV because they depreciate like vehicles — a key contrast with site-built dwellings that settle at replacement cost. Flood remains excluded and must come from the NFIP, and earthquake from a separate endorsement.
Seasonal, Vacant, and Builders-Risk Dwellings
Specialized dwelling situations need tailored coverage: seasonal dwellings (occupied part of the year) may face restricted theft and vacancy provisions; vacant dwellings need a vacancy permit because standard forms suspend vandalism and certain water perils after a vacancy period; and dwellings under construction are insured on a Builders Risk form covering the structure during the build, often on a completed-value basis with a reporting or 100% coinsurance condition. Flood always requires the NFIP, and earthquake a separate endorsement. The exam routes each unusual occupancy to the correct form or permit.
Worked Mobile-Home Valuation
A mobile home with an ACV of $40,000 suffers a covered total fire loss; it would cost $60,000 to replace new. Absent a replacement-cost endorsement, the Mobilehome program pays ACV = $40,000 (less deductible), because manufactured homes depreciate like vehicles. With a replacement-cost endorsement and adequate insurance-to-value, the insured could recover the full $60,000 replacement cost. This contrast — ACV by default, replacement cost only by endorsement — is the single most-tested mobile-home point.
