Kings County, California, handles building permits, including those for plumbing, through its Planning and Development Department, specifically the Building Division. This division is responsible for ensuring that all construction and building activities comply with state and local codes and regulations.

These plans are reviewed by the Building Division to ensure they meet the requirements of the California Plumbing Code and any local amendments. Once the plans are approved and the permit is issued, the work can commence. Inspections are then conducted at various stages of the project to verify that the work is being performed according to the approved plans and codes.

California Plumbing Legislation, Codes, and Guidelines
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.

- 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.
