Plumbing Estimating for California Contractors

California's Title 24 plumbing efficiency standards, seismic bracing requirements under CBC, and tiered water-use regulations make plumbing estimates here more complex than in most states. California requires a C-36 Plumbing Contractor license. Journeyman plumbers must hold a state-issued certification. Permit fees in LA and SF are among the highest in the nation.
