General Contractor Insurance Cost and Required Policies
General contractors coordinate multiple trades, supervise subcontractors, manage construction sites, and remain responsible for delivering completed projects. That broad role creates risks extending far beyond accidental damage caused by the contractor’s own employees.
A visitor could be injured at the jobsite, a subcontractor’s defective work could cause major water damage, construction materials could be stolen, or a partially completed structure could be damaged by fire or severe weather. General contractors also face vehicle accidents, workplace injuries, design disputes, construction delays, environmental exposures, and lawsuits arising after a project is finished.
For most general contractors, the core insurance package includes general liability, completed operations, workers’ compensation, commercial auto, and tools and equipment coverage. Builder’s risk, professional liability, commercial umbrella, pollution liability, and surety bonds may also be required depending on the contractor’s projects, business structure, and location.
How Much Does General Contractor Insurance Cost?
Insurance costs vary according to the policies purchased, business size, payroll, revenue, location, subcontractor use, project values, claims history, and coverage limits.
General contractors purchasing policies through Insureon pay the following published monthly and annual averages:
| Insurance Policy | Average Monthly Cost | Average Annual Cost |
|---|---|---|
| General liability insurance | $142 | $1,700 |
| Business owner’s policy | $121 | $1,455 |
| Workers’ compensation | $318 | $3,811 |
| Commercial auto insurance | $180 | $2,157 |
| Tools and equipment insurance | $14 | $169 |
| Professional liability insurance | $74 | $886 |
| Commercial umbrella insurance | $143 | $1,721 |
| Builder’s risk insurance | $134 | $1,608 |
| Surety bond premium | $10 | $125 |
These amounts are budgeting benchmarks rather than guaranteed prices. A business owner’s policy already includes general liability, so those two premiums should not normally be added together. Insureon notes that BOP pricing may appear lower because only smaller, lower-risk businesses typically qualify for the package.
NEXT provides another current comparison. Its July 2026 data states that general contractor insurance can begin at approximately $83.33 per month. It reports that 93% of its general contractor customers pay an average of $77 per month for general liability, with most paying between $57 and $224.
Example General Contractor Insurance Budgets
Using the Insureon averages, a solo general contractor purchasing general liability, commercial auto, and tools coverage could spend approximately:
- General liability: $142 per month
- Commercial auto: $180 per month
- Tools and equipment: $14 per month
- Estimated total: $336 per month
A contracting company with employees purchasing a business owner’s policy, workers’ compensation, commercial auto, and tools coverage could spend approximately:
- Business owner’s policy: $121 per month
- Workers’ compensation: $318 per month
- Commercial auto: $180 per month
- Tools and equipment: $14 per month
- Estimated total: $633 per month
Builder’s risk, umbrella insurance, professional liability, pollution coverage, additional vehicles, and higher contractual limits would increase the total.
What Determines General Contractor Insurance Costs?
Two general contractors with similar revenue can receive very different quotes because their work, subcontractors, and project values may create substantially different exposures.
Type and Size of Projects
Insurance pricing may differ based on whether the contractor performs:
- Residential remodeling
- New home construction
- Multifamily construction
- Commercial tenant improvements
- Structural renovations
- Industrial construction
- Roofing or excavation
- Design-build projects
- Government contracts
- High-rise construction
A contractor building custom homes has a different risk profile from one performing small kitchen renovations. Maximum project value, number of stories, construction type, and annual subcontracted costs can all affect underwriting.
Payroll and Employee Duties
Workers’ compensation premiums depend heavily on payroll, employee classifications, state rates, and claims history. Field employees, equipment operators, carpenters, and project managers who regularly visit jobsites may be rated differently from clerical employees working exclusively in an office.
Annual Revenue and Subcontractor Costs
General liability insurers commonly consider annual revenue and the amount paid to subcontractors. Greater construction volume creates more opportunities for injuries, property damage, and completed-operations claims.
A contractor that cannot provide valid subcontractor insurance certificates may also face additional charges during a premium audit.
Claims History
Previous claims involving water damage, construction defects, jobsite injuries, vehicle accidents, theft, or lawsuits can increase premiums. Severe or repeated losses may reduce the number of insurers willing to offer coverage.
Policy Limits and Contract Requirements
Higher limits generally cost more. Premiums may also increase when contracts require:
- Additional insured endorsements
- Primary and noncontributory wording
- Waivers of subrogation
- Extended completed-operations coverage
- Project-specific limits
- Higher employer’s liability limits
- Commercial umbrella insurance
General Liability Insurance
General liability insurance is the foundation of most general contractor insurance programs. The SBA describes it as protection against certain financial losses involving bodily injury, property damage, medical expenses, lawsuits, settlements, and judgments.
Common general contractor liability claims include:
- A customer trips over construction materials.
- Falling debris damages a neighboring vehicle.
- A worker damages existing flooring, walls, or fixtures.
- Construction activities damage underground utilities.
- Water enters a building during renovation.
- A visitor is injured at the jobsite.
- A subcontractor’s work causes separate property damage.
- Equipment or materials damage an adjacent property.
General contractors purchasing general liability through Insureon pay an average of $142 per month. Its average policy includes a $1 million per-occurrence limit, a $2 million aggregate limit, and a $1,000 deductible.
Does General Liability Cover Faulty Workmanship?
General liability generally does not pay simply because work was performed incorrectly and must be repaired or replaced.
It may, however, cover separate resulting damage.
For example, correcting an improperly installed window may remain the contractor’s responsibility. Interior water damage caused by that defective installation may qualify as resulting property damage, subject to the policy’s exclusions and conditions.
Completed Operations Coverage
Construction claims frequently appear after the project has been finished.
Examples include:
- A plumbing connection leaks after occupancy.
- Improper flashing causes interior water damage.
- A railing detaches and injures someone.
- Faulty electrical work causes a fire.
- Tile or flooring becomes loose and creates a fall hazard.
- A structural component damages other parts of the building.
Products-completed operations coverage is usually part of a commercial general liability policy. General contractors should confirm that it applies to the types of projects they manage and remains available for the period required by their contracts.
Coverage should also be reviewed for residential construction exclusions, condominium or tract-home limitations, subcontracted-work exclusions, and prior-work restrictions.
Workers’ Compensation Insurance
Workers’ compensation may provide medical treatment, partial wage replacement, disability benefits, rehabilitation, and death benefits after a covered work-related injury or occupational illness.
Construction employees may face falls, electrocution, machinery injuries, silica exposure, asbestos, falling materials, and struck-by accidents. OSHA classifies construction as a high-hazard industry because workers regularly encounter these serious exposures.
Workers’ compensation requirements for most private employers are determined at the state level. Employee thresholds, owner exemptions, benefits, and penalties therefore differ by jurisdiction.
A solo contractor may qualify for an exemption in some states, but a project owner or general contractor can still require proof of coverage. General liability insurance does not normally pay the owner’s medical expenses following a work injury.
Commercial Auto Insurance
General contractors use pickup trucks, vans, trailers, and other vehicles to transport employees, tools, materials, and equipment.
Commercial auto insurance may include:
- Bodily injury liability
- Property damage liability
- Collision coverage
- Comprehensive coverage
- Uninsured or underinsured motorist coverage
- Medical payments or personal injury protection
- Trailer coverage
- Permanently installed equipment coverage
General contractors purchasing commercial auto coverage through Insureon pay an average of $180 per month for a policy with an average $1 million limit.
Employees who use personal vehicles for estimates, supply pickups, or project visits may create a hired and non-owned auto exposure. This coverage protects the contracting business’s liability interest but does not replace the employee’s personal auto insurance.
Tools and Equipment Insurance
General contractors may own or rent thousands of dollars in portable property, including:
- Power tools
- Generators
- Compressors
- Ladders and scaffolding
- Surveying equipment
- Laser levels
- Jobsite computers
- Safety equipment
- Portable lighting
- Small construction machinery
Tools and equipment insurance, often written as inland marine coverage, can protect portable property while it is transported, stored away from the primary business location, or used at a project.
Insureon reports an average cost of $14 per month for a $5,000 policy limit. Equipment valued above $2,500 may need to be scheduled separately.
Builder’s Risk Insurance
Builder’s risk, also called course-of-construction insurance, protects a building while it is being constructed or substantially renovated.
Depending on the policy, it may cover:
- The structure under construction
- Building materials
- Temporary structures
- Materials in transit
- Materials stored off-site
- Fire, vandalism, theft, or wind damage
- Certain soft costs following a covered loss
General contractors purchasing builder’s risk through Insureon pay an average of $134 per month, although the actual premium depends heavily on project value, construction type, duration, location, and covered hazards.
The construction contract should clearly identify whether the owner, developer, or general contractor is responsible for purchasing builder’s risk.
Additional Policies a General Contractor May Need
Professional Liability Insurance
Professional liability may be important when the contractor provides design-build services, consulting, construction management, estimates, scheduling, specifications, or technical recommendations.
It may address certain claims involving professional negligence, design coordination errors, budget overruns, or delays that do not involve bodily injury or physical property damage.
Commercial Umbrella Insurance
Commercial umbrella insurance provides additional limits above qualifying general liability, commercial auto, and employer’s liability policies.
It may be required for commercial buildings, multifamily properties, government work, schools, hospitals, or projects with significant public exposure.
Contractors Pollution Liability
Pollution liability may be appropriate when projects involve:
- Mold
- Asbestos
- Lead-based paint
- Contaminated soil
- Fuel or chemical spills
- Demolition debris
- Hazardous materials
- Polluted runoff
Standard general liability policies frequently restrict pollution-related claims.
Surety Bonds
Surety bonds may be required for contractor licensing, public work, or private construction contracts. Common examples include license, bid, performance, and payment bonds.
Unlike traditional insurance, a surety may seek reimbursement from the contractor after paying a valid claim.
Subcontractor Insurance Requirements
General contractors should verify subcontractor insurance before work begins.
Required documentation may include:
- General liability certificates
- Workers’ compensation certificates
- Commercial auto coverage
- Contractor licenses
- Written subcontractor agreements
- Additional insured endorsements
- Waivers of subrogation
- Updated certificates after renewal
A certificate of insurance only summarizes coverage. It does not change the policy or guarantee that the subcontractor’s operations are covered.
General contractors may also have safety responsibilities even when subcontractors create or expose workers to hazards. OSHA’s multi-employer policy allows more than one employer to be cited, including a controlling employer that failed to exercise reasonable care in preventing or correcting a violation.
General Contractor Insurance Requirements by State
There is no single nationwide coverage requirement. Rules may come from state contractor boards, workers’ compensation laws, municipalities, motor vehicle laws, and customer contracts.
Florida
Florida active general and building contractors must maintain at least:
- $300,000 in liability insurance
- $50,000 in property damage insurance
Active licensees must also maintain workers’ compensation or qualify for an exemption.
Washington
Washington general contractors must maintain:
- A $30,000 continuous contractor surety bond
- $200,000 in public liability and $50,000 in property damage coverage, or
- A $250,000 combined single liability limit
The legal business name must match on the contractor registration, bond, and insurance certificate.
California
California licensed contractors must maintain a $25,000 contractor bond. Employers must carry workers’ compensation even if they have only one employee, although many contractors without employees can file an exemption.
California contractor LLCs must also maintain a $100,000 employee or worker bond and at least $1 million in liability insurance for five or fewer listed personnel. The liability requirement increases by $100,000 for each additional person, up to $5 million.
Oregon
Oregon’s published liability requirements include $500,000 per occurrence for a residential general contractor. Commercial general contractor requirements include a $2 million aggregate for Level 1 and a $1 million aggregate for Level 2.
These are minimum licensing examples. Customer contracts may require substantially higher limits.
How to Lower General Contractor Insurance Costs
General contractors may reduce long-term insurance expenses by:
- Maintaining a written safety program
- Screening subcontractors before hiring
- Collecting valid insurance certificates
- Using accurate payroll and revenue estimates
- Applying correct workers’ compensation classifications
- Reporting claims promptly
- Reviewing open claims and reserves
- Hiring drivers with acceptable records
- Securing tools, trailers, and jobsites
- Comparing equivalent policies from several insurers
- Bundling eligible coverage in a BOP
- Avoiding unnecessary overlap between policies
The lowest premium does not always provide the best value. A policy that excludes subcontracted work, residential construction, roofing, excavation, or completed operations may leave the contractor uninsured for its most important risks.
Frequently Asked Questions
How Much Is General Liability Insurance for a General Contractor?
General contractors purchasing through Insureon pay an average of $142 per month. NEXT reports that 93% of its general contractor customers pay an average of $77, with most paying between $57 and $224 per month.
Does a Self-Employed General Contractor Need Insurance?
A self-employed general contractor should generally consider general liability, completed operations, commercial auto, and tools coverage. Workers’ compensation requirements depend on state law, licensing rules, and whether the business has employees.
Does General Contractor Insurance Cover Subcontractors?
A general liability policy may cover certain liability arising from subcontracted work, but exclusions and conditions vary. Subcontractors should carry their own insurance, and the general contractor should obtain certificates and required endorsements.
Is Builder’s Risk Required?
Builder’s risk is not universally required by law, but it may be required by a construction contract, lender, owner, or developer. The contract should state which party is responsible for purchasing it.
Is a Contractor Bond the Same as Insurance?
No. Insurance protects the contractor against covered losses. A surety bond protects the licensing authority, project owner, or another party requiring the bond. The contractor may need to reimburse the surety after a valid claim.
Is $1 Million in General Liability Enough?
A $1 million per-occurrence and $2 million aggregate structure is common, but large residential, commercial, or public projects may require higher limits and commercial umbrella insurance.
Conclusion
General contractor insurance may cost a few hundred dollars per month for a small residential contractor or several thousand dollars for a larger company managing employees, vehicles, subcontractors, and high-value projects.
Most general contractors should begin with general liability, completed operations, workers’ compensation, commercial auto, and tools and equipment insurance. Builder’s risk, professional liability, pollution coverage, commercial umbrella insurance, and surety bonds may also be necessary.
Before purchasing coverage, verify every state, local, licensing, and contractual requirement that applies to the business. Provide the insurer with an accurate description of project types, maximum values, employees, subcontractors, vehicles, and services. A policy designed around the contractor’s real operations offers stronger protection than inexpensive coverage containing exclusions for the work the company performs.
