Summary
Operating as a licensed plumbing contractor in Concord, California requires compliance with both state and local regulations. At the state level, contractors must obtain a C-36 Plumbing Contractor License from the CSLB, maintain proper insurance coverage, and ensure all workers hold appropriate individual plumbing licenses.
