2013 California Mechanical Code

Based on the ANSI accredited American National Standard 2012 Uniform Mechanical Code, the California State amendments have been assembled into a convenient, single publication with hundreds of tables and diagrams.

Codes of practice attempt to minimize risk by specifying technical standards of design, materials, workmanship and maintenance for plumbing systems. The main aims of the code are:

  • To ensure that planners, administrators and mechanical system installers develop the required competency to ensure that the codes are applied and upheld;
  • That standards are set to ensure that mechanical assemblies, materials and technologies are safe and effective; 
  • To ensure that mechanical installations meet these standards; 

To ensure safety and effectiveness continuously through the proper maintenance of these installations.
