General Contractor Insurance
Most insurance agents will write you a general liability policy and move on. That is not a program. General contractors face a risk profile that is heavier than almost any other trade - massive completed operations exposure, high workers comp rates driven by physical demands and physical labor and jobsite hazards, expensive heavy equipment, and a constant need for surety bonds on public and commercial projects. If your agent is not building your insurance and bonding together, you are working with the wrong agent.
Grit Insurance Group is a national independent brokerage that specializes in contractor insurance and surety bonding. We build programs for general contractors across the country - from residential flatwork crews to structural GC operations bidding multi-million-dollar infrastructure projects. We handle the insurance, the bonds, and the strategy to grow your bonding capacity as your business grows.
What General Contractors Actually Need (And What Most Agents Miss)
General contracting is not a single trade - it is the management of every trade on the project. The exposures are broader, the liability is deeper, and the coverage gaps that destroy GC businesses are almost always where sub risk meets prime contractor responsibility. Here are the six core risks every general contractor carries.
1. Vicarious Liability From Subcontractor Work
This is the risk that defines general contracting. You hire subcontractors to perform work on your project. When that sub causes damage, injures someone, or performs defective work, the injured party sues the GC - not the sub. You are the deep pocket. You are the prime on the contract. You are the one the owner calls.
Vicarious liability means you can be held responsible for the actions of your subcontractors even when you did nothing wrong. Your GL policy needs to respond to these claims, but it also needs to work in coordination with your sub's insurance. That means requiring proper COIs, additional insured endorsements, and waiver of subrogation from every sub on every job. If you are not managing sub insurance compliance, you are self-insuring their mistakes.
2. Completed Operations Exposure
The project is done. The owner moved in. The punch list is closed. Then 14 months later, a roof leaks because the framing sub did not flash the penetrations correctly. A retaining wall fails because the excavation sub did not compact the backfill. The HVAC system causes mold because of a ductwork design coordination error. These are completed operations claims and they represent the longest tail of liability a GC carries.
Completed operations coverage is the part of your GL policy that responds after you leave the jobsite and the work is done. As the GC, you are responsible for the finished product - all of it - including the work your subs performed. Your completed operations limit should match your per-occurrence limit at minimum. Most commercial GCs need $2 million or higher. Cheaper policies reduce this limit or carry sub-limits that leave you exposed on the claims that matter most.
3. Builders Risk and Project Insurance
As the GC, you are typically responsible for carrying builders risk on the project. Builders risk protects the structure under construction, materials on site, and materials in transit from fire, wind, theft, vandalism, and other covered perils. On most commercial and public projects, the contract requires the GC to carry builders risk.
The cost is project-specific - it depends on construction type, project value, location, and duration. A $5 million wood-frame residential project in a wildfire zone is a very different risk than a $20 million concrete tilt-up warehouse. Your agent needs to quote builders risk on every project, not carry a blanket policy that does not fit the job. Gaps in builders risk coverage can leave you personally liable for damage to a structure you have not been paid for yet.
4. Subcontractor Default and Insurance Gaps
Your insurance program is only as strong as your worst sub's insurance. When a sub shows up with a lapsed policy, inadequate limits, or no workers comp, every claim they generate becomes your problem. A sub's employee gets hurt and has no workers comp - the injured worker files against the GC. A sub causes property damage with no GL - the owner looks to the GC's policy.
Managing subcontractor insurance compliance is not optional for a GC. It is a core business function. You need a system to collect COIs before any sub sets foot on your jobsite, verify that coverage is active and limits meet contract requirements, confirm additional insured and waiver of subrogation endorsements are in place, and track expiration dates throughout the project. The GCs who get this right protect their own insurance program. The ones who do not pay for it in claims.
5. Multi-Project Aggregate Exposure
Most GL policies carry a general aggregate limit - the maximum the policy will pay across all claims in a policy year. A GC running five projects simultaneously can burn through a $2 million aggregate faster than a single-trade sub running one job at a time. One serious claim on Project A reduces the coverage available for Projects B through E.
Per-project aggregates solve this problem. With a per-project aggregate endorsement, each project gets its own aggregate limit. This is standard on most commercial GC programs and many project owners require it in their contracts. If your policy does not include per-project aggregates, every project you run is sharing the same pool of coverage - and one bad claim can leave every other project exposed.
6. Contract and Compliance Risk
GCs sign contracts that contain insurance requirements - minimum limits, specific endorsements, named additional insureds, primary and non-contributory language, and waiver of subrogation. These are not suggestions. They are contractual obligations. If your insurance does not match what the contract requires, you are in breach before the first shovel hits dirt.
Every GC contract should be reviewed against your current insurance program before you sign it. Your agent should be the one doing this review - not your attorney and definitely not you. The cost of adding an endorsement or increasing a limit is almost always less than the cost of being out of compliance when a claim hits.
The Full General Contractor Insurance Program
Here is what a properly built insurance program looks like for a general contractor. Every line of coverage exists because GC work creates specific exposures that compound across every project and every subcontractor on the job.
General Liability
General liability is the foundation of every contractor insurance program. For general contractors, GL covers third-party bodily injury and property damage caused by your operations and your subcontractors' work. A visitor trips over debris on your jobsite. A crane load drops onto an adjacent property. A sub's excavation damages a utility line. As the GC, your GL policy is the first line of defense for all of it.
Standard limits for general contractors: $1,000,000 per occurrence and $2,000,000 aggregate. Most commercial and public project contracts require these minimums, and many owners require higher limits or per-project aggregates. Your policy should include strong completed operations coverage, blanket additional insured endorsements, primary and non-contributory language, and per-project aggregate endorsements.
GC rates are based on your project types, revenue, sub trades managed, and claims history. Underwriters know that GC claims involve multiple parties and tend to be complex and expensive. Your loss history and risk management practices directly affect your pricing.
Workers Compensation
Workers comp is mandatory in nearly every state once you have employees. For general contractors, the relevant class codes depend on what work your own crews perform. Class code 5606 covers construction executive and project management staff. If your crews self-perform trade work - framing (5403), concrete (5213/5222), demolition, or site prep - those higher-rated codes apply to those employees.
Workers comp rates for GCs vary significantly based on how much trade work you self-perform versus sub out. A GC with a crew of 10 framers and 5 laborers will pay substantially more than a GC with 3 project managers and an office staff. The more you sub out, the lower your direct comp costs - but you still carry exposure for sub injuries through vicarious liability.
Your experience modification rate (EMR) is the single most important number driving your workers comp cost. Every claim pushes it up. Every clean year brings it down. An EMR over 1.0 means you are paying a surcharge and may be disqualified from bidding on projects that cap the modifier. We help general contractors understand their mod, implement safety documentation, and build a path to a lower EMR over time.
Commercial Auto
General contractors operate mixed fleets - pickup trucks for project managers and superintendents, dump trucks and flatbeds if you self-perform site work, utility trailers hauling materials between jobsites, and sometimes heavy equipment transport. Commercial auto covers liability for accidents your drivers cause, physical damage to your vehicles, and medical payments.
Key coverage considerations for GCs: hired and non-owned auto coverage for when employees drive personal vehicles on company business, loading and unloading coverage, and proper liability limits that meet contract requirements. Most commercial projects require $1 million combined single limit at minimum.
Builders Risk
Builders risk is the coverage most unique to general contractors. It protects the structure under construction and all materials, fixtures, and equipment destined for installation. Fire, wind, theft, vandalism, water damage, and collapse are all covered perils on a properly written builders risk policy.
GCs typically carry builders risk because the construction contract assigns that responsibility to the prime contractor. The policy is project-specific - it covers one project for a defined construction period and is priced based on the total completed value, construction type, and location. Soft costs coverage, which pays for additional expenses like extended overhead, architect fees, and financing costs caused by a covered delay, is a valuable add-on that many GCs overlook.
Inland Marine and Equipment
If your company owns tools, equipment, scaffolding, temporary structures, or materials that move between jobsites, inland marine coverage protects them. Your commercial property policy does not cover equipment at job locations or in transit. Inland marine fills that gap.
For GCs who self-perform trade work, equipment values add up fast - forklifts, skid steers, generators, compressors, laser levels, power tools, and safety systems. Every piece should be scheduled on your inland marine policy with accurate replacement values. Equipment that is not scheduled is equipment that is not covered when it is stolen or destroyed.
Pollution Liability
Standard general liability policies contain a pollution exclusion. For general contractors managing construction sites, pollution exposure comes from multiple sources - stormwater runoff violations, fuel spills from equipment, disturbance of contaminated soil during excavation, lead paint or asbestos exposure during renovation, and dust from demolition and grading.
Contractors Pollution Liability (CPL) fills the gap your GL policy leaves. Many commercial and public project owners now require the GC to carry CPL. Even when it is not required by contract, the exposure is real. If a sub's work triggers an environmental cleanup on your project, the owner looks to the GC first.
Professional Liability and E&O
If your GC operation provides any design services, value engineering, constructability review, or design-build delivery, professional liability coverage is essential. Standard GL policies exclude claims arising from professional services - a design error that causes a structural problem is not covered under GL.
Design-build GCs, firms that provide engineering or architectural coordination, and GCs who take on construction management roles all need to evaluate their professional liability exposure. This coverage is less common for traditional plan-and-spec GCs, but the line between construction and design continues to blur in modern project delivery.
Umbrella and Excess Liability
General contractors face higher aggregate exposure than almost any other trade because they manage multiple projects, multiple subs, and multiple coverage lines simultaneously. A $2 million GL aggregate can disappear in a single serious claim - a multi-story fall, a crane accident, a fire that destroys a structure under construction, or a sub default that triggers a cascade of third-party claims.
Umbrella coverage sits on top of your GL, auto, and employers liability policies and provides additional limits when underlying policies are exhausted. Most commercial GCs carry $5 million to $10 million in umbrella coverage. Large GCs on public and institutional work carry $25 million or more. Many project owners specify minimum umbrella limits in their contracts - $5 million is increasingly the baseline.
Surety Bonds
If you bid on public construction - federal, state, county, or municipal - you need surety bonds. The Miller Act requires performance and payment bonds on federal projects over $150,000. Every state has a Little Miller Act with similar requirements for state-funded work. Many municipalities require bonds on infrastructure and building projects regardless of project size.
General contractors need three types of bonds: bid bonds (guaranteeing you will honor your bid price), performance bonds (guaranteeing you will complete the project), and payment bonds (guaranteeing you will pay your subs and suppliers). Your bonding capacity - the total amount of work you can have bonded at one time - is determined by your financial statements, working capital, experience, and track record.
Building a bonding program is one of the most strategic things a growing GC can do. Every dollar of bonding capacity unlocks access to projects you cannot bid without it. We help general contractors build their underwriting file, position their financials for surety approval, and grow their bonding capacity over time.

Subcontractor Insurance Management
This is not a coverage line - it is an operational discipline that directly affects every other coverage on this list. The GC's insurance program is only as strong as the sub compliance program behind it. Here is what a proper sub insurance management system looks like:
- COI collection before work starts - no certificate, no access to the jobsite
- Minimum limits verification - GL at $1M/$2M, workers comp at statutory, auto at $1M CSL at minimum
- Additional insured confirmation - the GC and owner must be named as additional insured on the sub's GL policy
- Primary and non-contributory language - the sub's policy responds first, not yours
- Waiver of subrogation - prevents the sub's insurer from coming after the GC to recover claim payments
- Expiration tracking - policies lapse mid-project more often than most GCs realize
- Workers comp verification - confirm the sub has active coverage and is not using an exemption to avoid it
The GCs who build this system protect their insurance program, their EMR, and their ability to bid bigger work. The GCs who skip it eventually pay for it in claims, premium increases, and lost project opportunities.
How Much Does General Contractor Insurance Cost?
General contractor insurance costs vary based on revenue, payroll, project types, number of employees, claims history, and bonding requirements. Here are general ranges based on the size of the operation:
- Small residential GC (3-5 employees, under $2M revenue): $10,000 to $25,000 per year for a basic program including GL, workers comp, and commercial auto
- Mid-size commercial GC (10-20 employees, $5M-$15M revenue): $40,000 to $120,000 per year including GL, workers comp, auto, umbrella, and builders risk on active projects
- Large commercial/public works GC (20+ employees, $15M+ revenue): $100,000 to $400,000+ per year for a full program with GL, workers comp, auto, umbrella, builders risk, pollution, and a surety bonding program
Workers compensation and general liability are typically the two largest cost drivers. Your EMR, sub-to-self-perform ratio, project types, and geographic footprint all affect pricing. GCs who self-perform high-risk trades pay more for workers comp. GCs who manage subs effectively and maintain clean loss histories pay less across the board.
Your GC operation is too complex to run on a lightweight insurance program.
Whether you need general liability, workers comp, builders risk, umbrella coverage, or a full surety bonding program to bid public and commercial work, the Grit team builds insurance for general contractors who are scaling and need a program that keeps pace with their growth.
