SB407

Senate Bill 407 (SB 407) requires noncompliant plumbing fixtures to be replaced by water-conserving plumbing fixtures when a property is undergoing alterations or improvements. This bill applies to all residential and commercial buildings constructed on or before January 1, 1994. Fixtures include water closets, urinals, showerheads, lavatory faucets, and kitchen faucets. Noncompliant fixtures can only be replaced by fixtures complying with the requirements of CALGreen and the California Plumbing Code.

Certain types of repair and maintenance projects do not trigger the upgrades at this time, such as electrical services, water heater replacement, re-roofs, window replacement, pools, signs and patios. Please check with Building & Safety Division at 818-238-5220 if you have any questions about the type of work you are doing and whether the code requires an upgrade.
