3.4 Mobile Home and Specialized Dwelling Coverage

Insuring the Mobile Home

A mobile or manufactured home cannot be insured directly on a standard DP or HO form, because those forms contemplate site-built construction and value retention. Instead, an insurer attaches the Mobile Home Endorsement (MH 04 01) to a Homeowners base form, or uses a dwelling form for rented units.

The endorsement modifies the policy so the manufactured home functions as the Coverage A dwelling, while Coverages B through E and the liability coverages flow through from the base form. Eligibility usually requires the unit to be at least a stated size, commonly 10 feet wide and 40 feet long, and designed and built for year-round living on a permanent chassis. Travel trailers and motor homes do not qualify; those are insured on auto or recreational-vehicle policies instead.

Coverage Structure

The lettered coverages parallel a standard dwelling, with mobile-specific twists:

Loss settlement on older mobile home forms is Actual Cash Value, reflecting the rapid depreciation of manufactured housing, although replacement-cost options exist. Adjacent structures permanently attached, such as awnings and cabanas, are typically included under Coverage A.

Transportation and Permission to Move

Unlike a site-built home, a mobile home may be relocated. The endorsement includes Transportation / Permission to Move coverage that protects the unit while it is being moved to a new permanent location. Typical terms:

• Coverage applies for 30 days from the start of the move
• A stated radius (often within the policy state or a set mileage) limits how far the move is covered
• Perils during transit are usually collision, upset, stranding, and sinking of the transporting vehicle

Exam tip: If a mobile home is damaged in a move the insured never reported, expect the answer to hinge on whether Permission to Move was in effect; coverage is conditional on notice and the time/radius limits.

Specialized Dwelling Situations

Several non-standard dwelling exposures change underwriting and claims handling:

• Dwelling under construction: insured under a builder's risk approach or the Dwelling Under Construction provision; the limit reflects the completed value, and premium is adjusted as value rises
• Seasonal dwelling: occupied only part of the year; insurers watch the vacancy/unoccupancy issue closely
• Vacant dwelling: most forms suspend or reduce certain perils, notably vandalism, glass breakage, and water damage, once the dwelling is vacant beyond 60 consecutive days

A frequently tested distinction: unoccupied means furnished but nobody home; vacant means empty of both people and contents. The vacancy provision triggers on the stricter vacant condition.

ACV Worked Example and Separate Perils

Mobile home physical-damage losses commonly settle on ACV because manufactured housing depreciates quickly. ACV equals replacement cost minus depreciation, and a straight-line method based on age over useful life is a common exam approach.

Suppose a manufactured home cost $80,000 new, has a 20-year useful life, and is 8 years old at the time of a total fire loss.

• Depreciation = 8 / 20 = 40%
• ACV = $80,000 x (1 - 0.40) = $48,000
• After a $1,000 deductible, the insurer pays $47,000

As with site-built dwellings, flood is written separately under the National Flood Insurance Program and earthquake is added by endorsement with its own percentage deductible. Neither peril is automatically covered on a mobile home policy, so a producer in a flood- or quake-exposed area must arrange coverage separately.

The Mobile Home Endorsement (DP / HO)

Manufactured (mobile) homes are insured by adding a Mobile Home Endorsement to either a Dwelling or Homeowners form. The endorsement adapts the dwelling form to a transportable structure built on a chassis. Coverage A insures the mobile home itself, and Coverage B (Other Structures) is typically reduced (often to 10% of Coverage A) because attached structures are less common.

A key add-on is transportation/permission-to-move coverage: standard policies do not cover the home while it is being moved unless an endorsement grants up to 30 days of coverage during a permitted relocation, protecting against collision, upset, and stranding while in transit.

Specialized and Higher-Risk Dwelling Coverage

For dwellings that cannot qualify for standard markets, the exam references several mechanisms:

Vacant or under-construction dwellings need special handling: a Dwelling Under Construction endorsement adjusts the limit as the structure rises, and a standard policy's vacancy provision suspends or reduces certain perils (such as vandalism and glass breakage) once a dwelling is vacant beyond a stated period (commonly 60 days). Trap: a fire loss in a long-vacant dwelling may face reduced or suspended coverage.
