CALIFORNIA PLUMBING CODE

The 2019 California Plumbing Code (CPC), Title 24, California Code of Regulations, is adopted by the city council. It is a modified 2018 International Plumbing Code and as published from time-to-time by the California Building Standards Commission. This code, which sets minimum standards for the installation, modification, repair, or replacement of plumbing, gas, and drainage systems, as well as inspection thereof, will be subject to some changes and amendments. The code can be inspected in person at the city clerk’s office.

The California State Amendments were based on the ANSI-accredited American National Standard 2018 Uniform Plumbing Code. They have been combined into a single publication with updates and errata pages.

These codes of practice are intended to reduce public risk by defining technical standards for design, materials, and maintenance of plumbing systems. These are the main goals of the code:

To ensure that plumbers, administrators, and planners have the necessary competency to ensure that codes are adhered to;

These standards were established to ensure that plumbing materials, technologies and assemblies are safe and efficient. These standards are to ensure that plumbing installations comply with them. These installations must be maintained in a safe and effective manner to ensure their safety and effectiveness.

California Plumbing Code Workshop

DWR, California Department of Housing and Community Development (HCD), and Building Standards Commission (BSC) invite you to a Zoom workshop where you can share and discuss proposed modifications.

DWR’s main focus is on safe and reliable use of recycled water.

(CPC), primarily covers standards for plumbing buildings with potable water and sanitary drainage. It also contains standards for plumbing for alternative water sources, such as rainwater, graywater and recycled water. DWR is statutory responsible for amending and adopting the CPC’s recycled water standards under Water Code Section 13557.

Based on the 2019 CPC as amended by 2020 and the 2021 Uniform Plumbing Code the proposed amendments may include references to new standards that will be set forth by the State Water Resources Control Board in accordance with Assembly Bill No. 1180 (2019). Concerning the use of a switch or changeover device to provide potable water to a dual plumbed system in case there is an interruption to recycled water service.

The proposed amendments to the DWR are being developed in coordination and with HCD and BSC amendments. HCD and BSC also propose other amendments to greywater and potable water.
