Construction Insurance: Coverage and Cost Guide

Which coverage lines construction companies actually need

Construction insurance is not one policy. The coverage you need depends on whether you frame houses, excavate utilities, install HVAC, or manage an entire project. A one-person painter, a roofing subcontractor, a utility excavation crew, and a commercial general contractor all face different exposures and contract requirements.

The bundle typically starts with three lines and expands from there based on your operations, employees, vehicles, and what your contracts require.

General liability (GL) for third-party claims

General liability is the baseline. It covers claims alleging bodily injury or property damage caused by your operations. A homeowner trips over your materials. Your excavator swings into a parked car. A ceiling you installed collapses onto furniture. GL is commonly required before a contractor can start a job.

Workers compensation (WC) for employee injuries

Workers compensation covers medical care, lost wages, disability, and death benefits for employees injured on the job. Most states require it as soon as you have employees. The premium is calculated from payroll and a class-code rate that reflects the injury risk of the work being performed.

Commercial auto for work vehicles

Commercial auto covers vehicles used to move workers, materials, tools, trailers, and equipment to job sites. Personal auto policies may exclude or limit coverage when a vehicle is titled to the business or used primarily for work. Individual tools and materials inside the vehicle usually are not covered under the auto policy.

Builders risk for projects under construction

Builders risk is temporary property coverage for structures and materials under construction or renovation. It should be in place by the time materials are delivered to the job site, not only when vertical construction begins. Coverage end triggers vary by policy form and may include owner acceptance, transfer of ownership, occupancy, or policy expiration.

Pollution liability, professional liability, and umbrella coverage

Contractors pollution liability is bought separately from general liability and can cover environmental damage at a third-party job site. It matters for excavation, demolition, fuel-tank work, utility trenching, and refrigerant-handling operations.

Professional liability (errors and omissions) applies when the contractor performs design, engineering, construction management, or consulting services. Some contracts require it with limits of $2 million or more per claim.

Umbrella or excess liability adds limits above general liability, commercial auto, and employers liability. Larger commercial or public contracts often require umbrella limits of $5 million or more.

Answer a few questions about your operations to see which coverage lines likely apply to your work.

What your contract requires before you start work

Most construction buyers land on this page because a general contractor, owner, or municipality handed them an insurance exhibit. That exhibit lists the exact coverage, limits, endorsements, and wording your policy must carry before you can mobilize.

A real construction services agreement filed with the SEC required statutory workers compensation, $1 million employers liability, $1 million per occurrence and $3 million aggregate commercial general liability (CGL) with a per-project endorsement, $1 million auto liability, $2 million/$5 million professional liability, additional insured endorsements, primary and noncontributory wording, and subcontractor flow-down insurance. That is one private contract, not a universal rule, but it shows how detailed real construction insurance exhibits can be.

Key endorsement terms in plain language

An additional insured endorsement gives the upstream party (the general contractor (GC) or owner) some protection under your policy for covered claims tied to your work. CG 20 10 covers ongoing operations. CG 20 37 covers completed operations after the job is done. Many construction contracts require both.

Primary and noncontributory wording sets the order in which policies respond to the same loss. Your policy pays first and does not seek contribution from the additional insured's own coverage. A certificate that only lists the customer as certificate holder may not satisfy this requirement unless the policy has the endorsement.

A waiver of subrogation means your insurer agrees not to pursue the additional insured for recovery after paying a covered claim on your behalf. Customers ask for both the waiver language in the contract and proof from the insurer that the endorsement is on the policy.

Federal contract insurance minimums

Federal contracts have their own schedule. FAR 28.307-2 requires at least $500,000 per occurrence bodily injury liability when general liability is required, at least $100,000 employers liability, and auto liability of at least $200,000 per person bodily injury, $500,000 per occurrence bodily injury, and $20,000 per occurrence property damage. Contracting officers can require additional coverage and higher limits for work on a government installation.

How carriers price a construction insurance account

There is no single "construction insurance" price. Each coverage line is priced differently, and the premium depends on specific details about your business. Workers compensation uses payroll and class-code rates. General liability often uses receipts, work type, and subcontractor cost. Commercial auto uses vehicle count, driver records, and radius. Builders risk uses project value, timeline, and construction type.

Carriers ask about the type of work, number of employees, coverage limits and deductibles, vehicles, location, claims history, and business revenue when pricing a contractor account.

Rating bases by coverage line

• Workers compensation: payroll amount multiplied by a class-code rate that reflects injury risk for the specific trade
• General liability: often based on receipts or payroll, adjusted for work type, residential vs commercial split, and subcontractor use
• Commercial auto: vehicle count, vehicle type, driver age and records, travel radius, and state
• Builders risk: project cost, location, timeline, square footage, construction type, and policy limit
• Umbrella: underlying limits, trade classification, and loss history

Details that raise the premium

Higher payroll, more vehicles, riskier work types (roofing, demolition, excavation), prior claims, higher limits, and subcontractor cost all push premiums up. Residential work with completed-operations exposure and tract or habitational construction can face additional underwriting scrutiny.

Comparing quotes from multiple carriers helps you see how different underwriters price the same account. The marketplace includes 400+ carriers and can compare your application with options that may fit your work.

When standard carriers decline construction work

Not every construction trade can get coverage from a standard online carrier. Some operations face declinations because of high loss frequency, large claim severity, or construction-defect exposure. A declination does not mean you are uninsurable. It means you need a carrier or program that specializes in that risk.

Trades that commonly face standard-market declinations

• Roofing (steep slope, commercial, and re-roofing)
• Demolition and structural dismantling
• Excavation and trenching with depth exposure
• Residential tract and habitational construction with defect exposure
• Contractors with prior large losses or OSHA citations

The small and mid-sized contractor landscape has become challenging, with rising defect claims, social inflation, and risk-transfer gaps putting pressure on residential construction accounts. Carriers are also pulling back on limits and maintaining a firm stance on exclusions for certain construction classes.

Specialty and surplus lines programs

Surplus lines carriers and specialty construction programs write work that standard carriers will not touch. These programs often require more detailed applications, safety documentation, and loss-control plans. Your quote request should include your project mix, safety controls, subcontractor management practices, and prior loss history so the carrier can evaluate the account.

Coverage gaps that cost construction companies real money

These are real enforcement actions against construction companies. Each one shows a gap that proper coverage, classification, or safety controls could have addressed. They are not insurance claim payouts. They are business costs that arise when coverage, compliance, or controls fail.

Worker misclassification fines and audit exposure

Fall-hazard enforcement and underwriting signals

A New Jersey framing and sheathing contractor faced $819,417 in proposed OSHA penalties after eight inspections found 32 alleged safety violations, including failure to provide required fall protection. Repeated OSHA citations signal to underwriters that the contractor's safety controls are inadequate. Carriers may decline to quote, non-renew, or surcharge accounts with a pattern of safety violations.

Subcontractor certificates and premium audit surprises

If your subcontractors do not carry their own workers compensation and general liability with the right endorsements, their payroll may be added to your audit and their claims may hit your policy.

Why carriers add uninsured sub payroll to your audit

When a subcontractor cannot produce a valid workers compensation certificate, the hiring contractor's carrier treats that sub's workers as the contractor's employees for premium purposes. At year-end audit, the carrier adds the sub's payroll to the contractor's policy and charges premium at the applicable class-code rate. For high-hazard trades, this can add thousands of dollars to the final premium.

Collecting certificates with the right endorsements

A certificate of insurance from your sub is only useful if it shows current dates, adequate limits, and the endorsements your own contract requires you to flow down. Some contract exhibits require the prime contractor to obtain subcontractor insurance "commensurate with the risk of their work" and not less than listed limits. Check your specific contract exhibit for the exact flow-down language.

Flowing contract requirements down to subcontractors protects you at audit and limits your liability when a sub causes a claim. Keep certificates on file before the sub starts work, not after.
