General Liability vs Builders Risk Insurance: What Every GC Needs

General liability insurance protects a contractor if their work injures a third party or damages existing property. Builder's risk insurance covers the physical structure being built and the materials on-site from fire, theft, wind, or vandalism. You absolutely need both for a major remodel or new build to avoid catastrophic out-of-pocket losses.

Look, if you're pulling permits and running jobs, you are carrying massive financial risk every time your crew steps onto a site. I see guys rolling the dice every day, assuming their standard liability policy covers everything from a stolen lumber package to a house burning down. It doesn't.

Understanding general liability vs builders risk isn't just administrative paperwork—it's the difference between retiring comfortably and bankrupting your company over one bad weekend.

Let's cut the insurance jargon. Here is exactly how these two policies work, what they actually cost, and how to structure them on your next job.

The Core Difference: General Liability vs Builders Risk

If you want to understand general liability vs builders risk, think of it like this:

General Liability is your armor against the outside world. It pays other people when you or your crew screw up and damage their stuff or hurt them.

Builder's Risk is the vault that protects the actual product you are building. It pays you (or the project owner) when an act of God, a thief, or a catastrophic accident destroys the materials or the unfinished structure.

General liability does not cover the building you are actively constructing. Builder's risk does not cover the neighbor's car if your roofer drops a bundle of shingles on it. You need both to close the loop on your job site risk.

General Liability: Your Shield Against Third-Party Disasters

General liability (GL) is the foundational insurance policy for any trade business. If you don't have this, you shouldn't be operating. Period.

What It Actually Covers

GL is broken down into a few main categories of coverage:

1. Premises Liability: A homeowner trips over your compressor hose in the hallway and breaks their hip. GL pays the medical bills and the inevitable lawsuit.
2. Property Damage: Your plumber is sweating a pipe, loses focus, and scorches the client's existing $15,000 imported marble floor. GL pays to replace the floor.
3. Completed Operations: You finish a deck build. Two years later, the ledger board fails because it wasn't flashed correctly. The deck collapses, injuring the homeowner. Your GL policy (specifically the Products-Completed Operations aggregate) covers the defense and settlement.

The "Your Work" Exclusion (Pay Attention Here)

Here is a brutal truth about GL: It does not pay to fix your bad work. It only pays for the damage caused by your bad work.

Let's say your drywall sub does a terrible job taping and mudding a $5,000 ceiling. It cracks a month later. You cannot file a GL claim to pay another crew to re-mud and paint the ceiling. That's on you.

However, if that same drywall sub accidentally drives a screw into a pressurized water line, and the resulting flood ruins the client's $20,000 hardwood floors on the level below, GL will pay for the floors. It just won't pay the $50 to patch the hole in the drywall.

What Does General Liability Cost?

For a residential general contractor doing around $1M to $2M in annual revenue, a standard policy with $1M per occurrence and $2M aggregate limits typically costs between $2,500 and $5,000 per year.

Your premium is audited annually based on your gross revenue and your subcontractor costs. If you want a deep dive into the math and limits, read our guide on what $1M actually covers.

Builder's Risk: Protecting the Project Itself

Builder's risk (also known as Course of Construction insurance) is a temporary policy. You buy it for a specific project, for a specific timeframe (usually 6, 9, or 12 months).

What It Actually Covers

Builder's risk protects the financial value of the unfinished project. It covers:

• The Structure: The framing, foundation, and roof as it goes up.
• Materials on Site: The $30,000 framing package sitting in the driveway.
• Materials in Transit: The custom cabinets being driven from the shop to the site (if endorsed properly).
• Fixtures and Appliances: The $10,000 Sub-Zero fridge waiting to be installed.

It protects these items against specific "perils"—most commonly fire, windstorms, hail, vandalism, and theft.

The Theft Reality

Let's talk about theft, because this is the #1 reason you need Builder's Risk.

Thieves love job sites. If you drop a load of OSB and copper wire on a Friday afternoon, there is a very real chance it's gone by Monday morning. If that happens, your General Liability policy will do absolutely nothing. The homeowner's standard insurance will do absolutely nothing.

Without Builder's Risk, you are writing a check out of your operating account to buy that material twice.

What Does Builder's Risk Cost?

Builder's risk is priced based on the total completed value of the project. A good rule of thumb is that it costs between 1% and 3% of the total construction cost, depending on the location (hurricane zones cost more) and the type of construction.

For a $500,000 custom build, expect to pay between $1,500 and $3,500 for a 12-month policy.

Most Contractors Get This Wrong: The "Existing Structure" Trap

This is the single biggest mistake I see remodelers make when looking at general liability vs builders risk.

Let's say you are hired to build a $300,000 second-story addition on a $1.2 million existing home. You think, "I have $2M in General Liability, so if I accidentally burn the house down, I'm covered."

Wrong.

Almost every General Liability policy contains a Care, Custody, or Control (CCC) exclusion. This clause states that your GL policy will not cover damage to property that is under your care, custody, or control.

If you take over an entire house to do a massive gut rehab, the insurance adjuster can successfully argue that the entire house was under your care, custody, and control. If a space heater catches fire and burns the $1.2M house to the foundation, your GL claim gets denied.

How do you fix this? You need a Builder's Risk policy that includes an Existing Structure Endorsement (sometimes called an Installation Floater for smaller jobs). This specifically insures the existing house against perils while you have it opened up. Never take on a major remodel without verifying how the existing structure is insured.

Cost Breakdown: Insurance on a $500k Custom Build

Let's look at exactly how this plays out on a real job. You are building a $500,000 custom home on an empty lot.

Here is how the insurance costs break down and who pays for what.

1. General Liability Allocation

Your GL is an annual policy paid out of your company's overhead. However, you need to allocate a portion of that cost to this specific job to ensure your margins stay healthy.

• Annual Revenue: $2,000,000
• Annual GL Premium: $5,000
• GL Cost as % of Revenue: 0.25%
• Allocation to $500k Job: $1,250

You don't show the client this number. This is buried in your standard overhead and markup. (If you aren't sure how to calculate this, check out our guide on how much profit a general contractor should make).

2. Builder's Risk Premium

Because this is a new build, you need a standalone Builder's Risk policy for the $500k completed value.

• Policy Term: 12 Months
• Deductible: $2,500
• Total Premium: $2,200

Who Pays the Builder's Risk Premium?

In residential construction, the client ultimately pays for the Builder's Risk policy, but you should be the one buying it and controlling it.

Some GCs tell the homeowner to go buy the Builder's Risk policy. This is a rookie move. If there is a $40,000 theft claim, do you really want to rely on the homeowner to file the paperwork, fight with the adjuster, and hand you the check? No. You want to be the First Named Insured so you control the payout and can keep the job moving.

Buy the policy yourself. Make the homeowner an Additional Insured. Take the $2,200 premium, mark it up 15% for administrative handling, and put it as a clear line item on your Schedule of Values: Course of Construction Insurance: $2,530.

What This Looks Like on a Job: Two Real-World Claims

To really cement the difference between general liability vs builders risk, let's look at two scenarios that happen to contractors every day.

Scenario 1: The Windstorm Collapse

You are framing a two-story custom home. It's dried in, but the windows aren't installed yet. Over the weekend, a freak microburst hits the neighborhood with 70mph winds. The wind catches the open structure like a parachute, snapping the shear walls and collapsing the entire second floor.

• Total Damage: $45,000 in ruined lumber and wasted labor.
• Which policy pays? Builder's Risk.
• How it works: Wind is a covered peril. You file the claim. The adjuster verifies the damage. You pay your $2,500 deductible, and the insurance company writes you a check for $42,500 to buy new lumber and pay your framers to rebuild it.

Scenario 2: The Errant Nail

You are doing a kitchen remodel. Your trim carpenter is installing baseboards. He shoots a 2-inch brad nail into the wall, hitting a PVC water line dead center. It doesn't leak immediately. Three days later, on a Sunday, the nail rusts enough to let the pressure blow the pipe open. Water floods the kitchen and seeps down into the finished basement, destroying custom drywall, carpet, and the client's $5,000 home theater system.

• Total Damage: $35,000 to the existing home and client's property.
• Which policy pays? General Liability.
• How it works: Because your subcontractor caused property damage to the client's existing property, your GL steps in. (Note: Your GL carrier will likely pay the claim and then subrogate—meaning they will go after your trim carpenter's GL policy to get their money back).

How to Handle Soft Costs on Builder's Risk

If you are doing high-end custom builds, you need to understand "Soft Costs" endorsements on your Builder's Risk policy.

Hard costs are bricks, sticks, and labor. Soft costs are the administrative fees tied to the project. If a fire burns your project to the ground at the 90% completion mark, you don't just have to buy lumber again. You have to pay for new architectural drawings, new permit fees, ongoing porta-potty rentals, extended scaffolding leases, and possibly extra interest on the construction loan.

A standard Builder's Risk policy only covers hard costs. You must explicitly ask your broker to add a Soft Costs endorsement. It usually costs a few hundred dollars extra, but it saves you from eating thousands in administrative overhead if you have to start a build over from scratch.

Managing Subcontractors' Insurance

Your General Liability policy is priced based on the assumption that your subcontractors have their own insurance. If they don't, your insurance company takes on their risk, and they will charge you heavily for it at your year-end audit.

Every time a sub steps on your site, you must have two things on file:

1. A Certificate of Insurance (COI): Proving they have at least $1M in General Liability.
2. Additional Insured Status: Their policy must list your company as an Additional Insured. This means if they burn the house down, the claim goes against their policy first, protecting your loss history.

Don't forget about workers' compensation, either. If a sub's employee falls off scaffolding and they don't have comp, that liability rolls straight uphill to you. Make sure you understand exactly workers comp for subcontractors before you let an uninsured roofing crew on your site.

Action Plan: What You Need to Do Tomorrow

Don't just read this and go back to swinging a hammer. Insurance is a profit-protection tool. If you don't have it dialed in, you are working for free the second a disaster strikes. Here is exactly what you need to do tomorrow morning:

1. Check Your CCC Exclusion: Pull out your General Liability policy. Look for the "Care, Custody, or Control" exclusion. Call your broker and ask: "If I am remodeling a kitchen and accidentally burn the entire house down, does this policy cover the existing structure, or is it excluded under CCC?" Get their answer in writing via email.
2. Standardize Your Builder's Risk Process: Stop making the homeowner buy it. On your very next job over $100k, call your broker and get a quote for a Builder's Risk policy in your company's name. Add a 15% markup to the premium and put it on your client estimate.
3. Audit Your Subs: Go through your active jobs. If you have a plumber, electrician, or framer on site who hasn't provided a COI listing you as an Additional Insured in the last 12 months, kick them off the site until they email it to you.

You work too hard for your margins to lose them to a stolen lumber package or a careless subcontractor. Get your paper right, protect the job site, and go build something profitable.

Frequently Asked Questions

Can I use general liability instead of builder's risk?

No. General liability covers damage you cause to other people or their property, but it explicitly excludes the building you are actively constructing and the materials you own on-site. You must have builder's risk to cover the actual project against theft, fire, or weather damage.

Who is responsible for buying the builder's risk policy?

Either the general contractor or the property owner can buy the policy. However, it is highly recommended that the general contractor buys it and lists the owner as an additional insured, ensuring the GC controls the claims process and the funds to rebuild.

Does builder's risk cover subcontractor mistakes?

Builder's risk covers the resulting physical damage to the structure (like a fire caused by a sub's faulty wiring), but it does not pay to fix the defective work itself. The subcontractor's general liability should be the primary target for damage caused by their negligence.

What happens to a builder's risk policy when the job is done?

Builder's risk policies expire automatically either on the date listed on the policy, when the building is occupied, or when the project is signed over to the owner. Once occupied, the property must be transitioned to a standard homeowner's or commercial property policy.
