3.4 Mobile Home and Specialized Dwelling Coverage
Key Takeaways
- Mobile homes are insured by endorsing a Homeowners or Dwelling policy (HO 04 28 / MH endorsement); ACV is the default settlement because they depreciate quickly.
- Mobile home endorsements add a transportation/removal coverage (commonly $500) to move the home out of an impending covered peril's path.
- Seasonal and secondary dwellings are commonly written on DP forms; vacancy beyond 60 days suspends vandalism, glass, and water coverage.
- Flood is excluded by every dwelling form; NFIP Dwelling Form maxima are $250,000 building / $100,000 contents with a 30-day waiting period.
- Dwelling Under Construction uses completed-value limits and is the personal-lines parallel to commercial Builders Risk.
Mobile Home Coverage
Mobile and manufactured homes are insured by endorsing a Homeowners or Dwelling policy with the Mobile Home endorsement (MH 04 01 / HO 04 28 Mobile Home Endorsement) or a dedicated mobilehome program. The HO-2 or HO-3 base, modified by the endorsement, is the most common personal-lines approach; rental or non-owner-occupied mobile homes use a Dwelling form with the mobile home endorsement.
Key differences from a standard dwelling:
- Coverage A insures the mobile home itself plus permanently installed items (appliances, dressers, cabinets, fixtures); the structure is movable, so valuation and the insurable-interest discussion differ.
- Loss settlement is typically ACV unless replacement cost is purchased, because mobile homes depreciate faster than site-built homes.
- A built-in transportation / removal coverage (commonly up to $500, or a stated limit) pays to move the home out of the path of an impending covered peril such as windstorm.
- Property Removed and emergency removal provisions parallel the dwelling forms but reflect the home's mobility.
Tested trap: a mobile home does not automatically get replacement cost; ACV is the default, reflecting rapid depreciation.
Specialized Dwelling Situations
Seasonal and Secondary Dwellings
Seasonal dwellings (occupied part of the year) and secondary homes are commonly written on a DP form rather than an HO policy, because the occupancy and contents pattern does not fit an owner-occupied Homeowners risk. Vacancy provisions matter: most property forms suspend or reduce coverage for vandalism, glass breakage, and water damage once the dwelling has been vacant more than 60 consecutive days, and any loss is then settled with reduced recovery.
Dwelling Under Construction
A dwelling under construction can be written on a DP form with a Dwelling Under Construction endorsement, which adjusts the Coverage A limit to the completed value while charging a provisional/average rate during the build. Materials and supplies on or adjacent to the premises are covered under Coverage A.
Builders Risk vs. Dwelling Under Construction
| Feature | Dwelling Under Construction (DP) | Builders Risk (commercial) |
|---|---|---|
| Program | Personal-lines dwelling endorsement | Commercial inland marine / property |
| Insured | Owner | Contractor or owner |
| Limit basis | Completed value | Completed value (reporting or fixed) |
| Typical use | One- to four-family homes | Larger/commercial projects |
National Flood Insurance Program (NFIP)
Flood is excluded by every dwelling form, so flood-prone dwellings need separate NFIP coverage. Standard NFIP Dwelling Form maximums: $250,000 building and $100,000 contents for a single-family residential structure. There is a 30-day waiting period before a new NFIP policy takes effect (with limited exceptions).
Worked Example — Mobile Home ACV Settlement
A mobile home written on a Dwelling form with the mobile home endorsement (ACV settlement, $1,000 deductible) has a replacement cost of $60,000 and is 8 years old against a 24-year expected life. A covered windstorm causes a $30,000 loss.
Depreciation rate = 8/24 = 33.3%. The depreciation applied to the loss portion = 0.333 × $30,000 = $10,000, so ACV of the damaged portion = $30,000 − $10,000 = $20,000. After the $1,000 deductible, the policy pays $19,000.
Had replacement cost coverage been purchased and insurance-to-value satisfied, the settlement would approach the full $30,000 loss less the deductible = $29,000 — again showing why settlement basis is the decisive variable on the exam.
Mobile Home Coverage Details the Exam Tests
Beyond the ACV default, the mobile home endorsement carries several testable features. Coverage A applies to the mobile home and attached structures (cabanas, awnings, carports) and built-in appliances; a small built-in limit (commonly 10% of Coverage A) extends to adjacent structures. Tip-over, collision, and upset in transit are addressed by the transportation/removal coverage, which also pays to remove the home from the path of an impending covered peril up to the stated limit. The endorsement may also add a property removal provision and an emergency removal window paralleling the dwelling forms.
Settlement, Vacancy, and Insurance-to-Value Traps
| Situation | Result on the exam |
|---|---|
| Mobile home, no RCV endorsement | ACV settlement (depreciation applies) |
| Dwelling vacant > 60 days | Vandalism, glass, and water losses suspended |
| Dwelling under construction | Coverage A tracks completed value |
| Flood loss, any DP form | Excluded — NFIP responds separately |
NFIP and Separate Catastrophe Coverage
Because flood and earthquake are excluded from every dwelling form, the producer must place separate coverage. The NFIP Dwelling Form caps a single-family structure at $250,000 building / $100,000 contents, with a 30-day waiting period before a new policy is effective (exceptions: loan closing, map revision). Earthquake is added either by the dwelling earthquake endorsement or a separate Difference in Conditions (DIC) policy for higher-value risks. Mapping a client's flood zone and confirming the waiting period are practical duties the exam frames as ethics/suitability questions.
Mobile Home Eligibility and Coverage Mechanics
A mobile home endorsement adapts a homeowners (usually HO-2 or HO-3) or dwelling policy to a manufactured home that is at least a defined size (commonly 10 feet wide and 40 feet long) and designed for year-round living. The structure is insured much like a dwelling, but two settlement wrinkles appear: many mobile-home policies settle the home on an actual cash value basis because of rapid depreciation, and they add transportation/permission to move coverage, often a stated sublimit (for example $500 to $1,000) for losses while the home is being relocated for the insured's safety.
Specialized Personal-Lines Forms
The dwelling and homeowners programs are surrounded by specialty forms the exam references. The HO-4 (contents broad / renters) form covers a tenant's personal property and liability with no building coverage. The HO-6 (unit-owners / condo) form covers a condominium owner's personal property, improvements and betterments, and liability, coordinating with the association's master policy.
The HO-8 (modified) form insures older homes on a functional/repair-cost and named-peril basis because replacement cost would exceed market value. Matching the right form to renter, condo owner, or historic-home fact patterns is a common task.
Watercraft, Recreational, and Inland Marine Floaters
For property that travels or has high concentrated value, personal inland marine floaters (the Personal Articles Floater and scheduled property endorsements) provide open-peril, often agreed-value coverage for jewelry, furs, fine art, cameras, and musical instruments without the homeowners theft sublimits. Small boats may be covered by the homeowners watercraft additions and sublimits, but larger boats need a separate boatowners or watercraft policy. Recognizing when a base form's sublimit forces the use of a floater is the key insight.
By default, how does a Dwelling or Homeowners policy with the mobile home endorsement settle a covered loss to the mobile home?
A standard NFIP Dwelling Form policy on a single-family home offers what maximum building and contents limits?
