Full Breakdown
Section 12.105.010 requires an owner or agent to obtain a building official's permit before erecting, installing, altering, or replacing any plumbing system regulated by the code. The plumbing standards themselves are the state-adopted California Plumbing Code, which Section 12.101.020.5 applies to installation, alteration, repair and replacement of plumbing fixtures, water and sewage connections, and private sewage disposal systems; San Rafael administers permitting locally but does not set its own plumbing technical standards. Minor exemptions exist under Section 12.105.020 for stopping pipe leaks, clearing stoppages, and residential fixture swaps that don't rearrange piping or require an electrical connection.
Violations & Fines
Starting regulated plumbing work without a permit triggers an investigation fee under Chapter 12.109 and can draw a stop-work order under Chapter 12.115.
