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.

- California Building Standards Commission (CBSC): The primary agency responsible for the formal rulemaking process, adoption, and publication of the California Building Standards Code (Title 24).
- Department of Housing and Community Development (HCD): Holds authority over building standards specifically related to residential housing.
- Contractors State License Board (CSLB): The agency responsible for licensing plumbing contractors (e.g., C-36 classification) to ensure that work is performed by qualified professionals.
