3.4 Mobile Home and Specialized Dwelling Coverage

Insuring Manufactured (Mobile) Homes

Mobile and manufactured homes do not fit the standard Dwelling building definition because they are transportable and depreciate differently. ISO addresses them with the Mobile Home Endorsement (Mobile Home Coverage Form / DP forms with the mobile home endorsement), which adapts a DP-2 or DP-3 to a manufactured home, or through Homeowners with the HO 04 28 Mobile Home Endorsement for owner-occupants.

To be eligible, the unit is generally a transportable structure at least a set size (commonly 8 feet wide x 32 feet long or about 320 square feet), designed for year-round living, and resting on a permanent or temporary foundation.

What the Mobile Home Endorsement Changes

The endorsement adapts the dwelling coverages to the manufactured-home exposure:

• Coverage A insures the mobile home itself, often on an actual cash value basis because of rapid depreciation, though replacement-cost options exist for newer units.
• Transportation/Removal coverage pays to move the home out of the path of an impending peril (e.g., flood or windstorm) - commonly limited to $500 with up to 30 days of coverage at the new location.
• Property removed and reasonable repairs to protect the unit are included.
• A reduced Coverage B (Other Structures) percentage often applies versus standard dwellings.

ACV vs. Replacement Cost Trap

Because manufactured homes can depreciate quickly, default settlement is frequently ACV (replacement cost minus depreciation). Exam math example:

A mobile home has a replacement cost of $90,000 and is 6 years into a 30-year useful life, so it has lost 20% to depreciation. A covered total loss occurs.

• Depreciation = 20% x $90,000 = $18,000.
• ACV = $90,000 - $18,000 = $72,000.
• The ACV policy pays $72,000 (less deductible), not the $90,000 replacement cost.

A replacement-cost endorsement would restore the $90,000 settlement subject to the limit.

Mobile Home Coverages and Limits

The mobile home form keeps the A-through-E lettered structure but adjusts several limits to the manufactured-home exposure. Coverage B (Other Structures) is frequently reduced to about 10% of Coverage A or $2,000, whichever is greater, and Coverage D/E often default to a percentage of Coverage A rather than Coverage C.

A distinctive feature is the broad collapse and transportation treatment: because the unit can be physically moved, the form contemplates losses in transit and the cost to relocate ahead of an oncoming peril. Anchoring, tie-downs, and skirting may be conditions of coverage in windstorm-prone states; failure to maintain them can reduce or void a wind claim — a common exam wrinkle.

Eligibility and Insurance-to-Value Pitfalls

A manufactured home must be designed for year-round permanent dwelling use to qualify; travel trailers and RVs used for recreation are insured under auto/recreational-vehicle forms instead, not the mobile home endorsement.

Insurance-to-value is the recurring trap: owners often insure the purchase price of a used unit, but a windstorm or fire settlement on an ACV basis can fall far below the loan balance, leaving the insured underwater. Producers should explain the ACV-versus-replacement-cost choice up front and document it. On the exam, expect to compute the depreciation-adjusted ACV and to recognize when a replacement-cost endorsement is the better recommendation.

Other Specialized Dwelling Situations

Trap: a condo unit owner is insured under an HO-6, not a Dwelling policy - the DP program does not cover individually owned condominium interiors. And a vacant dwelling triggers reduced perils (notably V&MM and glass) after 60 consecutive days unless a vacancy permit is added.

Manufactured-Home Specifics and Transport Exposures

Manufactured (mobile) homes are insured through a dwelling form plus the Mobile Home endorsement, which recognizes exposures a site-built home does not have.

Exam trap: Manufactured homes often settle at ACV, and they depreciate quickly, so a loss settlement can be far below the loan balance - a textbook insurance-to-value pitfall and a reason lenders demand specific coverage.

Coverages Added by the Endorsement

The Mobile Home endorsement typically provides:

• Coverage A on the home itself, often including attached structures and built-in appliances.
• Transportation/permission to move coverage for a limited period and distance, covering collision, upset, and stranding while the home is relocated.
• Property removal to protect the home from an oncoming peril.

Other Specialized Dwelling Situations

The dwelling program also handles seasonal dwellings (occupied part of the year - watch the vacancy rule), dwellings under renovation, and condominium unit-owner structures (where the association's master policy covers the building and the unit-owner insures interior improvements). Each situation changes which party insures which part of the structure, a recurring exam theme.
