Builder Insurance: Risk Protection for Residential Home Builders
A single uninsured event — a fire during construction, a worker injury, a roof failure two years after completion — can wipe out a home building company that took years to build. Insurance is not an optional expense for residential builders; it is the foundation of a sustainable business. This guide covers every insurance product a residential builder needs, what it costs, and the structural warranty programs that protect your business after project completion.

Builder's Risk Insurance: Protecting the Structure During Construction
Builder's risk insurance covers a structure under construction against physical loss or damage from fire, theft, vandalism, wind, lightning, and other specified perils. It is required by virtually every construction lender and protects the asset that represents your client's investment — and your business's financial exposure — during the construction period.
Builder's risk is typically written as a completed value policy: you insure for the projected completed value of the structure (not the construction cost, but the total value of the finished home). Premiums typically run $8–$15 per $1,000 of completed structure value. For a $500,000 finished home, expect annual builder's risk premiums of $4,000–$7,500. Policies are usually written for the construction period (6–18 months) and cancel automatically at project completion.
Key coverage points to verify with your broker: Does the policy cover theft of materials? Many basic builder's risk policies exclude materials theft; theft during construction is one of the most common losses. Does it cover collapse? Subsidence? Does it include soft costs coverage (architect fees, permit costs, carrying costs) if the structure must be rebuilt after a loss? ARGO Group and Philadelphia Insurance Companies are leading providers of builder's risk for residential construction.
Commercial General Liability: Your Foundation Coverage
Commercial general liability (CGL) insurance covers claims of bodily injury or property damage caused by your business operations or your completed work. For a home builder, this includes: a visitor injured on your job site (coverage under 'premises and operations' coverage), damage to a neighboring property caused by your construction activity, and a buyer's claim that a defect in your completed work caused them harm or damage.
Minimum CGL limits for home builders are $1M per occurrence and $2M aggregate. Many construction lenders and high-end clients require $2M per occurrence and $4M aggregate. For builders working on homes over $1M, consider $3M or $5M limits — the cost difference between $1M and $3M coverage is often less than $500/year, but the exposure difference on a high-value claim is enormous.
CGL premiums for home builders typically run $3,000–$8,000/year for a single-builder operation, varying by annual revenue, loss history, and the nature of your work. Premiums are typically higher for builders doing more speculative work (higher risk classification) than for custom build-to-suit where the completed home transfers to a titled owner at close.

Completed Operations Coverage
Completed operations coverage is a component of your CGL policy that covers bodily injury or property damage arising from your completed work — after the project is finished and turned over to the client. This is critically important for home builders, because construction defect claims often surface months or years after project completion.
A roof that develops a leak in year two, a foundation settlement claim in year three, or a structural failure in year five — if caused by your work — will be a completed operations claim. Without adequate completed operations coverage extending through your warranty period (and beyond, in states with extended statutes of repose for construction defects), you have no coverage for these claims.
Verify with your insurance broker that your CGL policy includes completed operations coverage and understand the coverage period. Many standard policies cover completed operations claims reported during the policy year — meaning if a claim surfaces five years after project completion and your policy did not extend coverage that far, you may have no coverage. Extended reporting endorsements and occurrence-based policies (which cover events that happened during the policy period regardless of when reported) provide broader protection.
Workers Compensation Insurance
Workers compensation covers medical costs and lost wages for employees injured on the job. Most states require workers comp for any business with employees. Even if you work solo with only subcontractors, understand your state's requirements: some states require owners to maintain workers comp even for themselves; others exempt owners but require coverage for any paid workers.
For builders who use subcontractors exclusively, the risk is that a subcontractor without their own workers comp coverage gets injured on your site and is deemed a statutory employee by your state workers comp authority — making you liable for their injury costs. The protection: require every subcontractor to provide a certificate of insurance showing active workers comp coverage before they step on your site. For subcontractors who carry no workers comp (often sole proprietors with a state-issued exemption), your own workers comp policy may cover them under your policy — which will increase your premium. Know how your policy handles sub coverage and price accordingly.
Workers comp premiums for home builders are calculated based on payroll and job classification codes. Framing work carries a higher risk classification (and higher premium) than finish carpentry. Make sure your payroll is correctly classified by trade type — misclassification is a common source of significant audit-driven premium adjustments.
Structural Warranty Programs: 2-10 Home Buyers Warranty
A structural warranty gives your buyers confidence that your work is backed beyond the construction period. The most established provider in the residential construction space is 2-10 Home Buyers Warranty (2-10.com), which has provided structural warranties on new homes since 1980.
The 2-10 HBW program provides a 1-year workmanship warranty, 2-year systems warranty (plumbing, electrical, HVAC), and 10-year structural defect warranty on new homes enrolled in the program. Builder enrollment fees range from $500–$700 per home depending on region and home size. The structural warranty is backed by 2-10 HBW's insurance carrier, not just your business — which means if you go out of business in year five, the structural warranty remains in force for the buyer.
Offering a 2-10 HBW warranty is a meaningful competitive differentiator for new builders who lack the track record to reassure buyers independently. Some construction lenders and certain state regulatory requirements also mandate structural warranties. Residential Warranty Corporation (RWC) is an alternative to 2-10 HBW worth comparing — both offer similar programs with different premium structures and geographic strengths.
Commercial Auto and Tools Coverage
If you use vehicles for business — driving to job sites, hauling tools, picking up materials — your personal auto insurance will not cover business use. Commercial auto insurance covers vehicles used primarily for business purposes and is required for any company-owned vehicles.
For a single-truck builder operation, commercial auto typically costs $1,200–$2,500/year for a standard pickup used for site visits and light material hauling. If you are pulling trailers, hauling equipment, or operating multiple company vehicles, premiums increase accordingly. Ensure your commercial auto policy covers tools and equipment stored in your vehicle — many commercial auto policies exclude theft of contents; this coverage needs to be added as an endorsement or covered under a separate tools and equipment policy.
Tools and equipment coverage (also called inland marine insurance) covers your tools, equipment, and materials against theft, damage, and loss on and off your job sites. A $500,000 homebuilder may have $30,000–$100,000 of tools and equipment — a comprehensive theft or fire loss at a job site is a major financial hit without this coverage. Annual premiums for tools coverage typically run $500–$1,500 for a small builder's tool inventory.
Building Your Complete Insurance Stack
A fully insured residential home builder carries: Builder's risk on each active construction project (required by lenders). Commercial general liability with completed operations coverage ($1M/$2M minimum, higher for larger projects). Workers compensation (required in most states, essential for all builders). Commercial auto for company vehicles. Tools and equipment coverage for field assets. And ideally, a structural warranty through 2-10 HBW or RWC for every completed home.
Work with a single broker who specializes in construction insurance — they can place all of these coverages with appropriate carriers, ensure there are no gaps between policies, and advise you on coverage limits appropriate for your project sizes and risk profile. An experienced construction broker will cost no more than a general broker and will provide substantially better coverage advice.
Budget $8,000–$18,000/year in insurance premiums for a solo builder doing $1M–$2M in annual project revenue. This is a real cost of doing business — but consider that a single uncovered claim (a worker injury, a major fire, a construction defect lawsuit) could cost $100,000–$1,000,000+. Insurance is the most efficient risk management tool available.

FREQUENTLY ASKED QUESTIONS
How much does builder's risk insurance cost per project?
Builder's risk premiums typically run $8–$15 per $1,000 of completed structure value. For a $500,000 finished home, expect $4,000–$7,500 for an annual policy covering the construction period. This cost is typically included in your project soft costs and should be built into your project estimate.
Does my CGL policy cover subcontractor work?
Your CGL covers work performed by subcontractors on your project for claims that arise from the operations of your project. However, if a subcontractor's work specifically causes a claim, your insurer may seek subrogation against the sub's insurer. This is why requiring every subcontractor to carry their own CGL with you named as additional insured is critical — it ensures direct coverage for subcontractor-caused claims without forcing your insurer to recover from a sub who may be inadequately insured.
Is a 2-10 HBW structural warranty required by law?
Not in most states, but some states have implied warranty statutes that create minimum warranty obligations for builders regardless of what the contract says. A few states — Louisiana, for example — have specific statutory new home warranty requirements. Some construction lenders require a third-party structural warranty as a loan condition. Even where not required, offering a 2-10 HBW warranty is strong competitive positioning for a builder trying to establish trust with first-project clients.
What is the difference between builder's risk and homeowner's insurance?
Builder's risk covers a structure under construction — before it is occupied. Homeowner's insurance covers a completed, occupied home. When a home is sold and the buyer closes, your builder's risk policy typically terminates and the buyer's homeowner's policy takes effect. Do not let builder's risk lapse before closing — there is a brief window at closing where you need both policies active simultaneously to avoid a coverage gap.
