Building standards: water conserving plumbing fixtures.

The California Building Standards Law provides for the adoption of building standards by state agencies by requiring all state agencies that adopt or propose adoption of any building standard to submit the building standard to the California Building Standards Commission for approval and adoption. Existing law requires the commission to publish, or cause to be published, editions of the California Building Standards Code in its entirety once every 3 years. Existing law requires the California Building Standards Commission to, among other things, research and assist in the development of mandatory green building standards for the installation of recycled water systems for newly constructed commercial and public buildings, as specified. This bill would require the California Building Standards Commission to develop regulations and mandatory building standards for the installation of water conserving plumbing fixtures, as defined, in existing nonresidential and public buildings, including installation in all nonresidential buildings by January 1, 2022.
