The California Plumbing Code (CPC) contains mechanical design and construction standards. Provisions contained in the CPC provide minimum standards to safeguard life or limb, health, property and public welfare by regulating and controlling the design, construction, installation, quality of materials, location, operation, and maintenance or use of heating, ventilating, cooling, refrigeration systems, incinerators and other miscellaneous heat-producing appliances. This is a fully integrated code based on the 2012 Uniform Plumbing Code
