Not much. A signed waiver can show what you and the worker agreed to, but it can’t make someone an independent contractor if California law says they are an employee, and it can’t cancel workers’ comp obligations. California presumes a person doing work that requires a contractor’s license is an employee, someone without the required contractor’s license can’t be an independent contractor for that work, and an employer can’t contract out of comp liability. If the worker gets hurt, a homeowner may be leaning on the homeowners policy. A contractor may be charged comp premium for an unlicensed, uninsured sub at audit, as State Compensation Insurance Fund warns its policyholders. A license check and proof of insurance do far more than a waiver.
What these waivers try to do
An uninsured contractor waiver, sometimes called an independent contractor insurance waiver or a hold-harmless form, is a document the worker signs saying they carry no workers’ comp, they are not your employee, and they won’t hold you responsible if they get hurt. Homeowners use them with handymen. General contractors use them with subs who show up without a certificate.
The form can be useful as a record of what everyone said. What it can’t do in California is change how the law classifies the worker, or take away workers’ comp rights the law gives an employee.
Why California may call the worker your employee
Three sections of the Labor Code do most of the work here.
- The license presumption (Labor Code 2750.5). A worker doing work that requires a contractor’s license under the Business and Professions Code is presumed to be an employee, not an independent contractor. The presumption can be rebutted. And anyone doing that work must hold a valid contractor’s license as a condition of being an independent contractor at all. An unlicensed person doing licensed work fails that condition, whatever the paperwork says.
- The ABC test (Labor Code 2775). A person providing labor or services for pay is an employee unless the hiring entity shows all three: they are free from its control and direction, the work is outside the usual course of its business, and they are customarily engaged in an independently established business of the same kind. The burden is on the one doing the hiring.
- The construction carve-out (Labor Code 2781). The relationship between a contractor and a construction subcontractor is judged under Labor Code 2750.5 and the older Borello standard instead of the ABC test, but only if the contractor shows every listed condition is met. Among them: the subcontract is in writing, the sub is licensed by the Contractors State License Board for that work, keeps a separate business location, can hire and fire, and takes financial responsibility for its work through insurance, indemnity obligations, performance bonds or warranties.
You can’t contract your way out of comp
Labor Code 5000 says no contract, rule or regulation exempts an employer from liability for the compensation the workers’ comp law sets. So if the worker turns out to be your employee, a waiver they signed doesn’t remove your obligation.
Going without coverage makes it worse. Under Labor Code 3706, when an employer has not secured payment of compensation, the injured employee can sue that employer for damages as if the comp system didn’t apply.
If you’re a homeowner
CSLB warns that if a worker is hurt on your property and the contractor has no insurance, you could be financially liable for the injuries and rehabilitation, and that your homeowner’s insurance may or may not cover those costs. It suggests checking with your insurance carrier.
California does build in some protection. Insurance Code 11590 requires any comprehensive personal liability policy issued or renewed in the state to include workers’ comp for household employees as defined in Labor Code 3351(d): people employed by the owner or occupant of a home whose duties are incidental to its ownership, maintenance or use. The limits matter:
- Business work is out. Under Insurance Code 11591, the requirement doesn’t apply when the work is part of your trade, business or profession.
- Very short jobs are out. Labor Code 3352 excludes a household worker whose employment in the 90 calendar days before the injury was, or was contracted to be, under 52 hours or for wages of no more than $100.
- It is comp, not everything. The requirement is about workers’ comp benefits. Damage the worker does to your home or a neighbor’s is a separate question. Ask your carrier before the job starts.
If you’re a general contractor
For a contractor with its own workers’ comp policy, the uninsured sub usually shows up at the premium audit. State Compensation Insurance Fund tells its policyholders that unlicensed people doing work that requires a contractor’s license are employees for workers’ comp purposes. If you can’t produce a certificate of insurance for a sub at audit and the sub has no valid license, it may treat that sub as your employee and charge premium for it. A signed waiver doesn’t change that. More on whether subcontractors need their own insurance.
What to collect instead
- A license check. Look up the license number on CSLB’s website or call CSLB. Seeing a license number doesn’t prove the license is valid. Ask to see the pocket license and a photo ID, and make sure the person matches the license.
- A workers’ comp certificate, or an exemption. Every licensee must have on file with CSLB a workers’ comp certificate, a state self-insurance certification, or a signed exemption saying it has no employees. Roofing (C-39), concrete (C-8), HVAC (C-20), asbestos abatement (C-22) and tree service (C-61/D-49) contractors can’t claim the exemption.
- A certificate of insurance, or the carrier and agency name so you can verify coverage. Make sure it covers your job dates. What a certificate of insurance shows.
- An additional insured endorsement if you’re a contractor hiring subs or your contract calls for it. How additional insured works on a contractor policy.
An exemption only means the contractor said it had no employees when it filed. Once it hires, that exemption is no longer valid and it must obtain comp coverage; CSLB must receive proof within 90 days of the hire. Hiring a handyman for small jobs?

Common questions
Is an independent contractor waiver legal in California?
You can have someone sign one, but it doesn’t decide whether they are an employee. Labor Code 5000 says no contract exempts an employer from workers’ comp liability.
If I hire an unlicensed contractor, am I their employer?
You may be. Labor Code 2750.5 presumes a worker doing work that requires a contractor’s license is an employee, and a valid contractor’s license is a condition of independent contractor status for that work.
Will my homeowners insurance cover an injured worker?
It may. California requires comprehensive personal liability policies to include workers’ comp for certain household employees, but business work and very short jobs are excluded. Ask your carrier before the job starts.
What if my subcontractor has a workers’ comp exemption on file?
That means the sub told CSLB it had no employees when it filed. Some trades, including roofing, can’t claim the exemption, and once a sub hires, its exemption is no longer valid; it must obtain coverage, and CSLB must receive proof within 90 days of the hire.
What should I get instead of a waiver?
A CSLB license check, the contractor’s workers’ comp certificate or exemption, a certificate of liability insurance, and an additional insured endorsement when your contract calls for one.
