Yes, California requires contractors performing restoration work to hold appropriate state licenses, and hiring an unlicensed contractor can void your homeowner's insurance.

Why Hiring a Licensed Restoration Contractor Matters in Castro Valley CDP, CA
California (CA) does not currently require a state-level license for restoration contractors. When hiring for sewage cleanup in Castro Valley CDP, this means there is no state oversight verifying contractor qualifications — making your own due diligence even more critical. Look for contractors who voluntarily carry general liability insurance, are bonded, and can provide proof of workers' compensation coverage.
Ask for IICRC certification numbers and verify them at iicrc.org. Request proof of pollution liability insurance specifically — standard general liability does not cover hazardous material incidents. Check that the company has experience with your specific type of damage and can provide references from similar projects.
Local municipalities in the Castro Valley CDP area may still require permits for certain restoration jobs. Ask your contractor about permit requirements before work begins.
