The Insurance Every Contractor Needs
Whether you are a sole proprietor just getting started or a seasoned GC running a crew of twenty, your insurance needs fall into the same basic categories. What changes is the limits, the cost, and which coverages are legally required versus practically required.
Here is the full breakdown.
Required by Law
Workers Compensation California, Nevada, Texas, and Arizona all have workers comp requirements, though the rules differ by state. In California, you need it the moment you hire one employee. There is no exception for part-time workers, family members working on the job, or day laborers.
Going without workers comp in California is a criminal offense. Penalties include fines up to $100,000 and stop-work orders from CSLB. Your license can be suspended or revoked.
Contractor License Bond California requires a $25,000 contractor license bond through the CSLB. This bond protects consumers if you fail to complete a job or violate your contract. It is not insurance; it is a guarantee that you will make the consumer whole. If the bonding company pays a claim, they come after you to recover the money.
Required by Every GC and Project Owner
General Liability Insurance Technically not required by California law, but you cannot work without it. Every general contractor, commercial property owner, and government agency requires GL before you can bid or start work. Standard minimums are $1 million per occurrence and $2 million aggregate.
GL covers:
- Third-party bodily injury (someone gets hurt because of your work)
- Property damage (your work damages someone else's property)
- Personal and advertising injury
- Completed operations (claims that arise after you finish the job)
- Products liability (materials you installed that fail)
Commercial Auto Insurance Your personal auto policy excludes business use. If you drive to job sites, haul materials, or have employees driving company vehicles, you need a commercial auto policy. Most GCs require it with $1 million combined single limit.
Strongly Recommended
Umbrella / Excess Liability An umbrella policy sits on top of your GL, auto, and employers liability. When a serious claim exceeds your underlying limits, the umbrella picks up the rest. A $1 million umbrella policy typically costs $300 to $600 per year, which makes it one of the best values in contractor insurance.
Large commercial projects and public works jobs often require $5 million or $10 million in total limits. You cannot get there with GL alone. An umbrella gets you there affordably.
Inland Marine Insurance Also called tools and equipment coverage. This protects your power tools, hand tools, and portable equipment from theft, damage, and loss. Your commercial auto policy covers the vehicle but not the $20,000 in tools in the truck bed. A standalone inland marine policy fills that gap.
Builders Risk Insurance Covers structures under construction against fire, wind, vandalism, and theft of materials. The property owner or GC usually carries this, but on some projects the sub is responsible. If you are doing a ground-up custom home as a GC, you need builders risk from the day you break ground until the owner takes occupancy.
Cyber Liability Insurance If you handle customer data, process credit card payments, use cloud-based project management, or have employee records stored digitally, you are exposed to data breach and ransomware risks. Cyber liability covers breach notification costs, forensic investigation, legal defense, and regulatory fines.
Professional Liability / E&O Design-build contractors, construction managers, and anyone providing professional opinions or design services needs E&O coverage. If your design recommendation causes a structural failure, GL will not cover it because it is a professional services error, not a construction accident.
Life Insurance Key person life insurance protects your business if you or a partner dies unexpectedly. Buy-sell agreements funded by life insurance let surviving partners buy out a deceased partner's share without draining the company.
How to Figure Out What You Need
Start with what is legally required and contractually demanded. Then work outward based on your risk exposure:
| Your Situation | What You Need | |----------------|---------------| | Sole proprietor, no employees | GL + contractor bond + commercial auto | | 1-5 employees | Add workers comp + inland marine | | Running crews on commercial jobs | Add umbrella to reach required limits | | GC on ground-up projects | Add builders risk | | Design-build or CM work | Add professional liability | | Any digital operations | Add cyber liability |
What It Costs
A typical California contractor with 3 employees, $500,000 in revenue, and standard risk can expect to pay roughly:
- GL: $1,500 to $2,500
- Workers comp: $3,000 to $8,000
- Commercial auto: $1,200 to $3,000
- Contractor bond: $100 to $300
- Umbrella ($1M): $300 to $600
- Inland marine: $300 to $800
Total: roughly $6,400 to $15,200 per year, or $530 to $1,270 per month.
That is the cost of staying legal, staying on job sites, and sleeping at night knowing one bad day does not wipe out everything you have built.
