What is Prefabricated Homes?
Prefabricated homes (also called prefab or modular homes) are built off-site in sections and assembled on a lot or foundation. Insurance for prefabricated homes provides protection for the dwelling and related liability exposures that differ from standard site-built houses because of construction methods, transportation risks, and installation processes.
Who needs it
Typical buyers include homeowners of manufactured or modular units, dealers and retailers who sell or store prefabricated sections, contractors who install or renovate these homes, and landlords who rent them. Builders of modular systems and haulers who transport large sections often need specialized coverage because they face commercial auto and equipment exposures as well as general liability and property risks.
What it typically covers
Coverage can vary by carrier but commonly includes:
- Property coverage for the structure, attached systems, and sometimes factory-built components during transit and after installation.
- General liability for bodily injury and property damage that occurs on the job site or at the customer’s property.
- Commercial auto or hauler coverage for transporting sections to the site.
- Builders’ risk or installation floaters to protect sections during assembly and unfinished work.
- Equipment coverage for cranes, lifts, and tools used during installation.

Common exclusions or limitations
Policies frequently exclude wear and tear, damage from improper installation, and some types of water or mold damage unless a specific endorsement is added. Liability for negligent workmanship or contractually assumed liabilities may be limited without a separate commercial liability or contractor’s policy. Transportation claims often require proof of specialized hauler coverage.
Factors that influence cost
Underwriting factors include the unit’s construction materials, whether the home is placed on a permanent foundation, the distance and method of transport, permitted use (owner-occupied vs. rental), prior claims history, and local building codes. Risk management measures such as certified installers, secure transport arrangements, and routine maintenance can lower premiums.
Proof of insurance & compliance
Dealers, haulers, and contractors are commonly asked to provide certificates of insurance for commercial liability, commercial auto, and equipment coverage. Dealers may use specialized programs tailored to the manufactured housing trade; see Affordable Home Services Manufactured Housing Dealer Insurance Program for an example of dealer-focused options: https://completemarkets.com/company/Affordable-Home-Services-Inc/manufactured-housing-dealer-insurance/
How to get a quote
Gather details about the unit (serial or HUD numbers when applicable), intended use, transport method, installation timeline, and any subcontractor arrangements. Haulers should have vehicle and cargo limits ready.

Frequently Asked Questions
Do prefab homes require different coverage than site-built homes?
Yes. Prefab homes often need coverage for transit, installation, and specific components; endorsements or separate policies (builders’ risk, hauler coverage) may be required.
Who is responsible if a section is damaged during transport?
Responsibility depends on contract terms and whether the transporter carries cargo or hauler insurance. Verify commercial auto and cargo limits before transport.
Can I insure a prefab home before it’s placed on a permanent foundation?
Yes. Temporary coverage such as builders’ risk or installation floaters are commonly available to protect sections from manufacture through installation.
