Overview
Manufactured and modular home contractors take factory-built housing sections from the plant or dealer lot and turn them into finished, livable homes on a customer's land. The work includes site preparation, foundation or pier-and-beam setup, transporting and craning sections into place, joining modules, anchoring and tie-down, and connecting plumbing, electrical, and HVAC. Crews also handle final trim, sealing the marriage line, skirting, and inspections before turnover. Because the home is built elsewhere and assembled on site, this contractor's risk straddles transportation, rigging, foundation work, and finishing trades all in one project.

Risk profile
The highest-value exposures occur while a home section is being transported and set: an oversize load can be damaged in transit, struck on the road, or dropped during the crane lift onto the foundation, with the contractor often responsible for a unit worth six figures. Foundation and tie-down errors can lead to settling, water intrusion, or anchoring failures that surface long after completion. Utility connections introduce electrical, gas, and plumbing exposures, and final finishing carries the usual workmanship risk. Crews face crush, fall, and lifting injuries during setting, and the trucks, trailers, and rigging used to deliver homes add auto and equipment exposure.
Common risks
Transit damage to home sections
Oversize modular sections can be damaged or struck while being hauled from the plant or dealer to the home site.
Drop or set error during craning
Lifting and placing a section onto the foundation risks dropping or misaligning a high-value unit in the contractor's care.
Foundation and tie-down failures
Improper piers, anchoring, or tie-downs can lead to settling, shifting, or water intrusion that emerges after the home is occupied.
Utility hookup hazards
Connecting electrical, gas, plumbing, and HVAC creates fire, leak, and code-compliance exposure if work is faulty.
Setting-crew injuries
Workers joining modules, crawling under units, and rigging lifts face fall, crush, and strain injuries during set and finish.
Workmanship and warranty disputes
Marriage-line leaks, trim defects, or finishing problems can prompt callbacks, warranty claims, and customer disputes.

Why tailored insurance matters
Because a factory-built home is most vulnerable while it is on the road and during the lift onto its foundation, this trade needs transit and installation coverage that ordinary builders may not carry. The contractor also absorbs foundation, hookup, and finishing exposures, blending several trades into one job. A program coordinating liability, auto, inland marine, builders risk, and workers' compensation may help align protection with how homes are delivered, set, and finished, subject to policy terms. Coverage availability depends on underwriting and the scope of work performed.
Hypothetical claim examples
Section damaged in transit
A modular section is struck and cracked while being hauled to the site. Inland marine transit coverage may respond, depending on policy terms, limits, and exclusions.
Storm damage before turnover
A storm damages a home being assembled on its foundation before completion. Builders risk may respond to covered damage, subject to the specific policy and provisions.
Tie-down failure causes shifting
Improper anchoring allows a home to shift, leading to a damage claim. Liability and completed-operations coverage may respond, depending on the policy and the facts.
Hypothetical scenarios for illustration only. Coverage depends on the specific policy, endorsements, exclusions, and facts of each claim.
What affects insurance cost
- Annual revenue and number of homes set per year
- Transport distance and oversize-load handling
- Value of home sections typically in your care
- Foundation and utility hookup work performed
- Owned trucks, trailers, and rigging
- Warranty practices and claims history
How much does it cost?
There is no single price for manufactured or modular home contractor insurance — it depends on which of these coverages you carry and the specifics of your business. As a rough guide, here are general national averages for the coverages this business commonly needs.
- $500–$1,500 per year for many small businesses
- $1,500–$3,000 per vehicle per year
- $300–$1,000 per year for many small businesses
- $500–$3,000 per year, driven largely by payroll and job class codes
- 1%–4% of construction cost for the project term
- 1%–3% of the bond amount per year for many qualified businesses
These are general national averages shown for comparison only — not a quote. Actual premiums vary widely with underwriting and depend on the factors above and the specifics of your business, including size, revenue, location, claims history, and the limits you choose. See how we estimate costs.
Coverage considerations
- Confirm transit and installation-floater limits for home sections
- Review builders risk through completion and turnover
- Verify auto coverage for oversize hauling
- Assess completed-operations and warranty exposure
- Check licensing and bonding requirements
Common underwriting considerations
When insurers review a manufactured or modular home contractor business, they commonly evaluate factors like these. This is educational information — nothing here is collected or submitted.
- Trades performed and the share of higher-risk work such as roofing or structural
- Annual revenue, payroll, and typical project size
- Use of subcontractors and the certificates and agreements collected from them
- Years in business, licensing, and claims history
- Heights worked, depths excavated, and safety programs in place
- Vehicle and equipment fleets and who operates them
Common contractual insurance requirements
Contracts, leases, and licenses in this industry commonly impose insurance requirements such as these. Always review the specific wording in your own agreements.
- Construction contracts routinely require additional-insured status, primary-and-noncontributory wording, and waivers of subrogation
- Project owners and GCs set minimum general liability, auto, and umbrella limits
- Completed-operations coverage is commonly required for years after project close-out
- Public work frequently requires bid, performance, and payment bonds
- Certificates of insurance are required before mobilizing on nearly every job
Common coverage mistakes
Mistakes businesses in this industry commonly make when arranging coverage — worth reviewing before you buy or renew.
- Starting work before contract insurance requirements are met
- Using uninsured subcontractors and absorbing their losses at audit or claim time
- Assuming tools and equipment are covered away from the shop without inland marine
- Overlooking completed-operations exposure after a project is finished
- Misclassifying payroll and facing large premium-audit adjustments
Frequently asked questions
How is a modular home covered while being transported?
Transit coverage under inland marine may respond to damage while hauling sections to the site. Coverage depends on the specific policy, limits, and exclusions.
Do I need builders risk if the home is factory-built?
Often yes. Once a home is being assembled on its foundation, builders risk may respond to fire, storm, or theft before turnover, subject to policy terms and provisions.
Who is responsible if a section is dropped during the set?
The setting contractor often has care of the unit during the lift, so installation coverage matters. Response depends on the policy, endorsements, and the facts of the loss.
Are utility hookups covered under my liability policy?
Faulty electrical, gas, or plumbing connections may involve liability and completed-operations coverage. Response depends on the specific policy, exclusions, and the facts.
Do I need workers' compensation for a small setting crew?
If you have employees, it is commonly required and helps with fall, crush, and lifting injuries during setting. Requirements vary by state and are subject to underwriting.
Will my auto policy cover hauling oversize sections?
Business auto can cover the trucks and trailers, but oversize loads may need specific terms. Coverage depends on the policy, the vehicles scheduled, and underwriting.
