California Plumbing Code and Legislation

In California, plumbing standards are governed by the California Plumbing Code (CPC), which is Part 5 of Title 24 of the California Code of Regulations. Unlike many other states that adopt the International Plumbing Code (IPC), California bases its plumbing code on the Uniform Plumbing Code (UPC). The state integrates the UPC with specific California amendments to address unique regional requirements, such as seismic safety, water conservation, and drought management.

The California Building Standards Code is updated on a triennial cycle. As of April 2026, the 2025 California Plumbing Code is the current enforceable standard, having taken effect on January 1, 2026. These regulations apply to all new construction, major renovations, and plumbing system installations across residential, commercial, and industrial properties throughout the state.
