Construction Insurance for Builders: What You Need, What Your Lender Requires, and How to Verify Your Subs Are Covered

Insurance is a cost of doing business in residential construction that most builders know they need but few fully understand until a lender asks for documentation or something goes wrong on a job site. Getting the right coverage in place before you break ground is not complicated, but the details matter. Wrong policy limits, a lapsed certificate, or a sub with no workers’ compensation can create liability that reaches back to you personally.

This guide covers the core policies every residential builder should carry, when each one needs to be in place, what your construction lender will require before releasing funds, and how to build a sub insurance verification process that actually works.

What Insurance Does a Residential Builder Need?

A residential home builder or general contractor typically needs four core insurance policies: general liability, builder’s risk, workers’ compensation, and commercial auto. Each covers a different category of risk and none of them substitute for the others.

General liability covers third-party bodily injury and property damage claims. Builder’s risk covers the structure and materials during construction against fire, theft, storm damage, and vandalism. Workers’ compensation covers employees injured on the job. Commercial auto covers vehicles used for business purposes that a personal auto policy will not cover.

Some builders also carry inland marine coverage for tools and equipment, an umbrella policy for excess liability, and a completed operations endorsement on their GL that extends coverage after project completion. Those are worth knowing about but are not the starting point. Start with the four core policies and add from there based on your specific operation.

General Liability Insurance

General liability is the policy most people think of first when they hear construction insurance. It covers bodily injury to third parties on your job site, property damage caused by your operations, and in some cases completed operations claims after a project is finished.

What general liability does not cover: your own employees (that is workers’ compensation), your own equipment and tools (that is inland marine), and the structure you are building (that is builder’s risk). General liability is specifically about claims made by people outside your business for injuries or damage you caused.

Standard minimum limits for a residential GC are $1 million per occurrence and $2 million aggregate. Your construction lender will almost certainly require proof of general liability at these minimums or higher before the loan closes or draws begin. Many lenders require being named as an additional interested party on your policy. Your commercial insurance agent can add this to your certificate of insurance (COI) at no cost.

One general liability detail that matters significantly on residential projects: completed operations coverage. Standard GL policies cover claims that arise during construction. Completed operations extends coverage for claims that surface after the project is done, such as a structural failure or water intrusion that becomes apparent months after you handed over the keys. If you are building spec homes or custom homes for clients, completed operations coverage is worth carrying.

Builder’s Risk Insurance

Builder’s risk insurance, also called course of construction insurance, covers the physical structure and materials on a project against fire, theft, vandalism, wind, hail, and most weather-related damage. It is the policy that protects what you are building while you are building it.

Builder’s risk does not cover liability. If someone trips and breaks their arm on your job site, that is a general liability claim, not a builder’s risk claim. Builder’s risk is strictly property coverage for the structure and the materials tied to it.

The most important timing detail: builder’s risk needs to be in place at lot closing, not at permit approval. If you take ownership of a lot and a fire destroys materials stored on site before you have pulled permits, builder’s risk should be covering that. Many first-time builders assume they have time between closing and breaking ground to sort out insurance. They do not. Bind the policy before you close on the lot.

Policy term is typically set to match your projected construction timeline. If you expect a 10-month build, you get a 10-month policy. If the project runs long, you extend the policy. Letting builder’s risk lapse before a CO is issued is a risk management failure that occasionally becomes an expensive one.

The cost of builder’s risk typically runs 1% to 5% of total budgeted construction cost annually. On a $400,000 build with a 10-month timeline, expect to pay $2,500 to $5,000 for the policy depending on the carrier, location, construction type, and coverage options selected. Budget this as a line item in your pre-construction costs.

On a contract build for a client rather than a spec home, who pays for builder’s risk should be addressed explicitly in the construction contract. Some GCs carry it and build the premium into their contract price. Some contracts require the owner to purchase it. The contract structure you are using and your lender’s requirements will typically guide this decision. What matters is that the policy exists and is active before the project starts, regardless of who pays for it.

Workers’ Compensation Insurance

Workers’ compensation covers medical costs and lost wages for employees injured on the job. It is required in nearly every state if you have employees on your payroll, and the penalties for operating without it are significant in most jurisdictions.

If you have no employees and operate as a sole proprietor or with only sub labor, workers’ comp requirements vary by state. Some states allow sole proprietors to exempt themselves. Others require coverage regardless. Check your state’s requirements directly through the state’s workers’ compensation board before assuming you are exempt.

The sub workers’ comp risk is where residential builders most commonly get burned. If a subcontractor does not carry their own workers’ compensation and one of their workers is injured on your site, you can be held liable for the claim in many states. The sub being an independent contractor does not automatically protect you. If the relationship is determined to look like employment, your workers’ comp carrier or the injured worker’s attorney will look to you for coverage.

The solution is the same as for general liability: collect certificates of insurance from every sub before they start work and verify that workers’ compensation is listed with active coverage dates. If a sub claims they are exempt under a sole proprietor exemption, get that documentation in writing. Do not accept verbal assurances. Managing subcontractors professionally means having the paperwork before the first day on site, not after an incident has already occurred.

Workers’ comp premiums are calculated as a percentage of payroll, with rates varying significantly by trade classification. Framing and roofing labor carries much higher rates than clerical or supervisory roles. If you are misclassifying field labor as administrative staff in your payroll records to reduce premiums, that is workers’ comp fraud. The audit that follows a significant claim will catch it.

Commercial Auto Insurance

Any vehicle used for business purposes needs a commercial auto policy. Your personal auto insurance policy will typically exclude coverage for accidents that occur while the vehicle is being used for business, including driving to job sites, hauling materials, or transporting tools and equipment.

If you use your personal truck for everything and have never separated business and personal auto coverage, talk to your insurance agent about whether a commercial auto policy or a business use endorsement on your personal policy is the right fit. The cost difference is usually modest and the coverage gap can be significant if you are ever in an accident while on the way to a job site without the right policy in place.

Optional Coverage Worth Carrying

Inland marine. Covers tools, equipment, and materials in transit or at the job site that builder’s risk does not cover. If your truck gets broken into and $8,000 in tools are stolen, builder’s risk will not pay that claim. Inland marine will. For builders who invest significantly in owned equipment, this is worth adding.

Umbrella or excess liability. Sits above your general liability policy and provides additional limits if a claim exceeds your primary policy’s per-occurrence cap. On larger projects or in higher-litigation markets, a $1 million umbrella is relatively inexpensive and adds meaningful protection. Many lenders on larger residential projects require it.

Completed operations extension. If your general liability policy does not include ongoing completed operations coverage as a standard feature, confirm the coverage period. Claims for construction defects often surface 12 to 36 months after completion. A policy that terminates at project closeout leaves that window uninsured.

What Your Construction Lender Will Require

Before your first draw is released, your lender will typically require certificates of insurance confirming that your general liability and builder’s risk policies are active, at minimum. Specific requirements vary by lender but the baseline is consistent across most residential construction lending.

Common lender insurance requirements for residential construction loans:

• General liability: $1 million per occurrence / $2 million aggregate minimum
• Builder’s risk: coverage equal to the full value of the completed project
• Workers’ compensation: required if you have employees; exempt status documentation if you do not
• Lender named as additional insured or loss payee on builder’s risk
• COIs delivered at loan closing before first draw

Your lender may also require you to collect and submit COIs from your major subcontractors as part of draw documentation, particularly for larger draws tied to structural phases. Draw releases on construction loans involve a lender inspector approving completed work. Having your insurance documentation in order before that inspection is part of keeping the draw process moving without delays.

For owner-builders financing through an owner-builder construction loan, lender insurance requirements are the same and in some cases more stringent. An owner-builder without a licensed GC on the project is a higher-risk profile for lenders, and insurance documentation will be scrutinized closely at underwriting.

How to Verify Sub Insurance Before Work Starts

Collecting a certificate of insurance from every sub before they start work is the most important step in managing your construction insurance exposure. A COI is a one-page document issued by the sub’s insurance agent that shows policy types, coverage limits, and expiration dates. It is proof of coverage, not the policy itself.

What to check on every COI you receive:

• Coverage types: GL and workers’ comp should both be listed for any sub with employees
• Coverage limits: GL at $1 million per occurrence minimum; higher for trades with greater risk exposure
• Policy dates: active on the date the sub starts work and through project completion
• Your company named as additional insured on the general liability policy

The additional insured distinction matters. Being listed as a certificate holder on a COI means you receive notice if the policy is cancelled. Being listed as an additional insured means you have coverage under the sub’s GL policy for claims arising from their work. These are not the same thing. Require additional insured status, not just certificate holder status, for every sub working on your project.

COIs expire. A sub who provided a valid COI in January may have let their policy lapse by April. Build a tracking log that notes each sub’s COI expiration date and flag any that will expire before work is complete. Ask for updated certificates before the old ones expire. This sounds tedious and it is, but an uninsured sub on your site during an active phase of work is a liability exposure that insurance cannot fix retroactively. Similar to lien waiver collection, the builders who handle this well are the ones who make it part of their standard pre-work documentation process rather than chasing it after something goes wrong.

Frequently Asked Questions

What insurance does a residential home builder need?

A residential home builder typically needs four core policies: general liability insurance covering third-party injury and property damage, builder’s risk insurance covering the structure and materials during construction, workers’ compensation if you have employees, and commercial auto if you use vehicles for business purposes. Additional coverage like inland marine for tools and equipment or an umbrella policy for excess liability is worth considering depending on your operation.

When does builder’s risk insurance need to be in place?

Builder’s risk insurance should be bound and active at lot closing, before any materials are delivered to the site or construction begins. Many builders make the mistake of waiting until permit approval, leaving a gap between lot purchase and the start of formal construction when materials and the site are still exposed. Bind the policy before you close on the lot.

Does a general contractor need workers’ compensation insurance?

If you have employees on payroll, workers’ compensation is required in nearly every state. If you operate as a sole proprietor with no employees and use only subcontracted labor, requirements vary by state. Even without your own employees, you can face workers’ comp liability if a subcontractor without coverage has a worker injured on your site. Collecting certificates of insurance from every sub is the protection against that exposure.

What is a certificate of insurance and why does it matter in construction?

A certificate of insurance is a one-page summary of a sub’s or contractor’s active insurance policies, issued by their insurance agent. It shows coverage types, limits, and expiration dates. In construction, COIs are collected from every subcontractor before they start work to confirm they carry their own coverage. Being listed as an additional insured on a sub’s COI means you have coverage under their GL policy for claims arising from their work, which is different from and more valuable than simply being listed as a certificate holder.

What does a construction lender require for insurance?

Most residential construction lenders require proof of active general liability at $1 million per occurrence or higher and builder’s risk coverage equal to the full project value before releasing the first draw. Workers’ compensation documentation is typically required if you have employees. The lender will usually want to be named as an additional insured on the builder’s risk policy and may require COIs from major subcontractors as part of draw documentation.

Getting insurance right before a project starts is straightforward when you know what you need. The problems arise when builders treat it as a last-minute checklist item, purchase minimum coverage without understanding what it does and does not cover, or assume a sub’s verbal confirmation of coverage is the same as a certificate on file. Set up your policies early, collect sub COIs before day one, and verify the lender requirements before your loan closes.
