General liability insurance for construction businesses

General liability insurance covers basic risks in the construction industry, like accidental damage to a client's property or a customer injury. It protects your small business from the high costs of lawsuits and helps you qualify for leases and contracts.

Why is general liability insurance important for construction businesses?

Whether a customer trips over a welder’s power cord, a carpenter installs an unstable staircase, or an excavation contractor accidentally damages a homeowner’s property, working in the construction industry comes with a lot of potential risks.

Without the proper insurance, your small business could be stuck paying for an incident out-of-pocket—and the costs can be substantial.

General liability insurance provides contractors and construction businesses with crucial financial protection against these risks, helping to pay expenses related to third-party bodily injuries and property damage.

Plus, a general liability insurance certificate can help you meet the insurance requirements of most contracts, leases, and professional licenses.

What can general liability insurance cover for construction businesses and contractors?

If a visitor is injured at your jobsite or an employee accidentally damages a home during a renovation, the cost for medical care, property repairs, or a proper legal defense can be devastating for a small business.

General liability insurance can help cover these expenses, paying for:

Customer injuries

Jobsites can be dangerous places, filled with tools, equipment, and other potential hazards. If a customer trips and falls while you’re installing their new flooring, you could be blamed for their injury.

A general liability policy would cover:

  • Attorney fees
  • Court-ordered judgments
  • Settlements
  • Medical expenses
  • Funeral expenses in fatal incidents

Keep in mind, this policy covers third-party injuries and does not include employee injuries. For that, you’ll need to purchase workers’ compensation insurance.

Customer property damage

Accidents can be costly for builders and contractors. General liability insurance safeguards small businesses when client property is damaged during construction projects.

For example, if a client’s furniture is damaged during remodeling, your general liability policy could help pay for the cost of repair or replacement. This policy can also cover the cost of a lawsuit if a client decides to take you to court over damaged property.

Defamation and infringement

While advertising your company and its construction services, it’s possible to inadvertently copy a competitor’s slogan or mimic another advertising campaign. Accidental advertising injuries are covered by general liability insurance, including:

Product liability

Construction businesses and contractors should make sure their contractor liability insurance includes product liability insurance, also known as products-completed operations coverage. This insurance protects your business if your finished work causes a bodily injury or property damage due to faulty workmanship.

For example, a home remodeler installs defective window seals, which allow water to seep in and create a substantial mold problem inside the house. This policy will help cover the contractor’s legal fees if the homeowner files a lawsuit due to the faulty installation.

Is construction liability insurance coverage required for contractors?

While laws vary by state, many require contractors to have construction liability insurance to obtain the proper licensing. Even if your state doesn’t have these laws, general liability insurance is recommended for all contractors, due to the highly hazardous nature of the construction industry.

Here’s an overview of the requirements and benefits of liability insurance for some of the most common types of contractors:

General contractors

Some states, including California and Florida, will require general contractors to purchase general liability insurance to obtain a license.

Construction liability insurance protects general contractors from potentially devastating financial losses due to third-party claims of bodily injury or property damage.

For example, if a general contractor’s ladder tips over and smashes a homeowner’s windshield, general liability would cover the cost to repair the damaged vehicle.

Handymen

General liability insurance is key for handymen, whose work on client property can present many risks for accidental property damage or customer bodily injury. It's also required in some states in order to get your license.

For example, in Georgia, any handyman who works on projects worth more than $2,500 must have a Residential Contractor license. To obtain this license, you must show proof of general liability insurance and workers' compensation insurance.

If a visitor is injured by falling tools, this policy will handle their medical bills, including emergency room visits and medication.

Roofing contractors

Roofing is a high-risk job filled with constant threats of property damage and third-party bodily injury, which can lead to expensive lawsuits, medical expenses, and other catastrophic costs.

Let’s say a homeowner sues a roofer for water damage after they’ve gotten a new roof installed. General liability insurance would cover the roofing contractor’s legal defense, including attorney fees, settlements, or judgments.

Plus, many states require liability insurance to obtain a roofer’s license. For example, Florida requires roofers to hold a license, which requires proof of liability insurance.

Electricians

If an electrician unintentionally damages a client’s property or causes an injury, general liability insurance is vital for covering claims of faulty work, protecting against lawsuits, and meeting contract requirements for certain jobs.

Should a general contractor require that an electrician be insured before they’ll be hired for a project, having an active general liability insurance policy can help the electrician get the job and earn professional credibility in the industry.

Additionally, some states mandate general liability insurance for electrician contractor licenses, including Arizona, Nevada, and Mississippi.

Plumbers

On top of jobsite risks, many claims can happen after a project is complete, making general liability insurance extremely important for plumbers. This policy covers claims of faulty workmanship, protecting you from financial ruin for repairing work or damages.

Depending on where you work, some states and cities require liability insurance to receive a license. For example, although New York doesn't have a statewide mandate for insurance or bonding, New York City requires plumbers to have a minimum of $1,000,000 in general liability insurance, per occurrence, as well as workers’ compensation insurance.

Should a plumber install a faulty sink, which floods a homeowner’s kitchen and destroys their expensive wood floor, general liability insurance would cover the bill to replace the floor and any other damage caused by the incident.

FAQs about general liability insurance for construction contractors

Get answers to frequently asked questions about general liability coverage for your construction business.

Do I need a certificate of liability insurance for my construction business?

A certificate of insurance (COI) is the official proof of coverage that you receive from your insurance provider when you purchase a policy. Also known as an ACORD 25 form, COIs are often required to work with certain clients, sign a lease, or take out a loan. They can also help you win project bids over uninsured competitors.

A COI includes important information about your policy, such as:

  • Type of coverage
  • Policy number
  • Per-occurrence and aggregate coverage limits
  • Exclusions
  • Effective policy term dates

To obtain a certificate of liability insurance, you must have an active insurance policy. If you already have an active policy, contact your Insureon agent or log in to your account with our Customer Portal to download or request a certificate.

What is often excluded from builders general liability insurance?

While general liability insurance is important for most construction businesses, it doesn’t cover all the risks your business can face. You might need to purchase other business insurance policies to fill coverage gaps and make up for general liability insurance exclusions.

Here are the most common exclusions from a commercial general liability policy:

  • Criminal acts: General liability doesn’t cover illegal actions or criminal acts. For example, if your equipment or tools are stolen from a jobsite, the policy wouldn’t pay to replace the items.
  • Preventable risks: Third-party bodily injury and property damage claims caused by preventable risks are generally excluded. So, if a customer slips on the icy walkway outside your office because you didn’t put salt down, the claim wouldn’t be covered.
  • Subcontractors: General liability insurance doesn’t cover damage caused by a subcontractor who is working for you. Additionally, an action over exclusion clause can deny coverage for bodily injuries suffered by a subcontractor if the claim is passed on to the insured party through a lawsuit.
  • Intentional acts: If you or an employee cause deliberate damage or harm, such as if a disgruntled contractor destroys a homeowner’s property, a general liability policy wouldn’t cover the damages.

Can I extend my general liability coverage to subcontractors?

If a subcontractor you hire causes damage, such as breaking a homeowner’s window, and they’re uninsured and not included in your policy, you could be responsible for repair costs and legal expenses.

To avoid these financial risks, you can extend your general liability insurance coverage to your subcontractors by adding them to your policy as an additional insured endorsement.

Another option is a controlled insurance program (CIP). Also called wrap insurance, CIPs bundle general liability, workers’ comp, and other types of coverage into one project-specific policy for all contractors and subcontractors involved.

There are two types of coverage options for CIPs:

  • Contractor-controlled insurance program (CCIP): With CCIPs, the general contractor purchases and manages the policy. This option streamlines claims and is typically cheaper when the risk is assumed by an experienced general contractor.
  • Owner-controlled insurance program (OCIP): OCIPs are purchased by the project or property owner. This option is often used for larger projects as they tend to be more expensive and offer broader coverage.

What other types of insurance should construction companies and contractors consider?

While commercial general liability insurance covers basic construction industry risks, it does not offer absolute protection. Other policies to consider include:

How do I save money on general liability insurance for my construction business?

If you run a small construction company or are an independent contractor, there are ways you can save on your business insurance. You may be able to bundle general liability coverage with commercial property insurance in a business owner’s policy (BOP). A BOP offers more complete coverage at a lower cost than purchasing each policy separately.

Businesses that are eligible for a BOP typically:

  • Have fewer than 100 employees
  • Have a small office or workplace
  • Make less than $1 million in annual revenue
  • Operate in a low-risk industry
  • Need less than 12 months of business interruption insurance

A business owner's policy covers damage to your building and its contents, such as fires and storm damage. If you don’t have a building, you can add business personal property (BPP) coverage to your general liability policy, or buy tools and equipment insurance to protect items brought to jobsites.

Talk to a licensed Insureon agent to find out if your construction business is eligible for a BOP.
