New Retrofitting Law for Plumbing
Effective Jan. 1, 2014, property owners who obtain permits to remodel a property that was built prior to 1994 are required to retrofit with toilets that use no more than 1.6 gallons per flush, showerheads with flow rates of no more than 2.5 gallons per minute, and other interior fixtures that use less than 2.2 gallons of water per minute.
This applies to all single-family property permits, as well as multifamily and commercial property permits where 10 percent or more of the square footage is included in the remodel.
By Jan. 1, 2017, all residential properties in California that were built prior to 1994 will need to be in compliance with water fixtures as outlined above, which will bring them up to the same standards as homes built since 1994.
