Plumbing Fixture Requirements

 SB 407 Certification Form

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 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.

The SB 407 requirements are triggered by all building alterations and improvements for the following:

SINGLE-FAMILY RESIDENTIAL

   o   All single-family residential additions, remodels, alterations and improvements.

MULTI-FAMILY RESIDENTIAL

   o   Building additions which increase the floor area of the space in a building by more than 10%
   o   Building alterations or improvements in which the total construction cost is greater than $150,000
   o   Alterations or improvements to a room in a building that contains any noncompliant plumbing fixtures

COMMERCIAL

   o   Building additions which increase the floor area of the space in a building by more than 10%
   o   Building alterations or improvements in which the total construction cost is greater than $150,000
   o   Alterations or improvements to a room in a building that contains any noncompliant plumbing fixtures

Tenant improvements within a multi-tenant building will be considered as a room in a building. Only the plumbing fixtures within the tenant’s area must be replaced. Common fixtures within the building not controlled by the tenant will not be required to be replaced under a tenant improvement permit.

   

FLOW RATES

The charts below show the noncompliant and compliant flow rates for plumbing fixtures based on category of structure. Fixtures with noncompliant flow rates (middle column) in a building built on or before January 1, 1994, need to be replaced with fxtures that operate at current approved rates (last column) as found in the California Plumbing Code and the CALGreen, as applicable. The property owner can submit the SB 407 Certification Form to their inspector prior to or at the time of final building inspection.
