State License
STATE C-36Plumbing
Plumbing contractors operating in San Francisco must navigate both state-level licensing through the CSLB and local regulatory requirements managed by the San Francisco Department of Building Inspection (DBI). The C-36 license is the baseline requirement for any project exceeding $500, ensuring the contractor has met state standards for trade knowledge and financial responsibility.
At the local level, San Francisco enforces strict building codes, including specific water conservation mandates and seismic bracing requirements for water heaters. Contractors are responsible for obtaining permits before starting work, scheduling mandatory inspections, and ensuring that all installations meet the current California Plumbing Code as adopted by the city.
Compliance requires a dual-track approach: maintaining state licensure while adhering to city-specific building and zoning ordinances.
