Learning from Other Contractors' Expensive Lessons
The same insurance mistakes cause serious problems for contractors again and again. Here's what to avoid, updated for the rule changes California contractors face in 2026 and beyond.
Mistake #1: Buying Minimum Coverage to Save Money
Saving a few hundred dollars on premium by carrying inadequate limits is false economy. A serious injury claim can exceed $1 million. If your policy maxes out at $300,000, you're personally responsible for the rest.
Picture a worker who falls through an unsecured floor opening and suffers permanent injuries. If the settlement is several times your limit, the difference can come from your house, your equipment, and your business.
Match your limits to your actual exposure, not your minimum legal requirements. Claim severity has kept rising; see how much liability coverage you need.
Mistake #2: Calling Employees Independent Contractors
Misclassifying workers creates major exposure. Workers' comp audits catch this, and the back premium can be large. If someone you've called an independent contractor gets hurt and has no coverage, you can be liable for their injuries, and in California, operating without required workers' comp can bring a stop order and penalties under Labor Code 3722 that are capped at $100,000, except for the separately calculated subdivision (b) penalties, which are not subject to that cap.
Beyond insurance, the IRS and California both enforce worker classification rules. The financial and legal consequences stack up fast.
If someone shows up when you tell them to, uses your tools, and does what you direct them to do, they're probably an employee regardless of what your paperwork says. Our independent contractor vs. employee guide explains California's ABC test.
Mistake #3: Letting Coverage Lapse
A gap in coverage creates multiple problems. In California, a lapse in required workers' comp leads to suspension of your license. Claims during uninsured periods come out of your pocket. When you reinstate coverage, you may pay more and lose credits you'd earned.
This mistake is about to affect more contractors. C-8, C-20, C-22, C-39, and C-49 licensees already must carry workers' comp even with no employees, and starting January 1, 2028, nearly every license will (SB 216 as amended by SB 1455). See our SB 216 guide.
Set up automatic payments. Work with an agency that monitors renewals and sends reminders. Even a short lapse can cause problems that take a long time to fix.
Mistake #4: Assuming Subcontractors Are Covered
"They said they have insurance" isn't verification. Collect certificates before work begins. Verify the limits meet your requirements. Confirm your company is listed as additional insured.
When an uninsured or underinsured sub causes damage or injury, you're on the hook. Their lack of coverage becomes your problem. If a sub's ceiling installation fails and damages the owner's equipment, and the sub let its GL lapse, the claim lands on the GC's policy and loss history instead.
Mistake #5: Signing Contracts Without Reading Insurance Requirements
Construction contracts include insurance provisions that specify coverage types, minimum limits, required endorsements, and compliance deadlines. Signing without reviewing these sections leads to problems.
You might discover after signing that you need endorsements your policy doesn't include, limits higher than you carry, or specialty coverage you've never purchased. Now you're scrambling, paying rush fees, or worst case, unable to comply with a contract you've already signed.
Have your agent review insurance requirements before you sign. Fifteen minutes of review beats weeks of problems.
Mistake #6: Waiting to Report Claims
Contractors sometimes hope small incidents will go away on their own. They won't. Delaying claim reporting can result in denied coverage for late notification, lost evidence and unavailable witnesses, and worse outcomes from delayed response.
Report every incident immediately, even minor ones. Let the insurance company decide whether it's significant. That's their job.
Mistake #7: Underestimating Payroll on Workers' Comp
Low-balling your payroll estimate to get a lower deposit sounds smart until the audit. When auditors discover actual payroll exceeding your estimates, you get a large bill for the difference. Significant underreporting can trigger fraud investigations and policy cancellation.
Give accurate estimates. If business picks up mid-year, notify your carrier. Adjust as you go rather than getting hammered at audit time. Budget for rate changes too: for California policies starting on or after September 1, 2026, the average advisory pure premium rate rose 6.6% to $1.65 per $100 of payroll. See what the September 2026 change means.
Mistake #8: Using Personal Vehicles for Business
Personal auto policies exclude regular business use. If you're visiting job sites, hauling materials, or transporting employees in your personal truck, your personal policy probably won't cover an accident.
The claim denial letter is when most contractors learn about this exclusion. By then it's too late.
Get commercial auto coverage for all business vehicles. Add hired and non-owned coverage for employees using personal vehicles for work errands.
Mistake #9: Operating Without Umbrella Coverage
Your primary policies have limits. When claims exceed those limits, you pay the difference from your own assets. Umbrella policies are usually a cost-effective way to add protection.
An umbrella typically costs far less than the primary policies it sits on, and much less than what you could lose in a major judgment. If you're doing commercial work or have significant personal assets, treat umbrella coverage as a must-have.
Mistake #10: Not Actually Reading Your Policy
Most contractors file their policies and never look at them again until there's a claim. By then, discovering you lack coverage for something you assumed was included is too late.
Policies have exclusions. Endorsements modify coverage. Limits apply in specific ways. Understanding what you bought before you need it prevents unpleasant surprises.
Ask your agent to walk through your policy's key provisions and exclusions. Know what you have.
Getting Your Program Right
Insurance is one of the most important investments you make in your business. Don't treat it as an afterthought or a box to check.
Work with specialists who understand construction risks. Get regular reviews as your business evolves. Fix problems before they turn into claims.
Common Questions
What's the first step if I've made some of these mistakes?
Get a comprehensive review of your current program. You can request a free quote and coverage review. The sooner you address problems, the better.
How often should I review coverage?
At minimum annually, at renewal time. Also review whenever you add services, hire employees, buy equipment, or take on larger projects. Your coverage should match your current operation.
Can you help if my situation is complicated?
Yes. We regularly work with contractors who have claims history, coverage gaps, misclassification issues, and other problems. These situations require more work, but solutions exist.
