Water: use efficiency: graywater building standards.

Existing law authorizes a city, county, or other local agency to adopt, after a public hearing and enactment of an ordinance or resolution, building standards that prohibit entirely the use of graywater, or building standards that are more restrictive than the graywater building standards adopted by the Department of Housing and Community Development and published in the California Building Standards Code. This bill would repeal the authority of a city, county, or other local agency to adopt building standards that prohibit entirely the use of graywater and instead authorize the adoption, under specified requirements, of standards that are more restrictive than that adopted pursuant to state requirements. The bill would require that an ordinance enacted pursuant to this authority include the local climatic, geological, topographical, or public health conditions requiring different building standards. The bill would also require a city, county, or other local agency to seek consultation with the local public health department prior to commencing the issuance of permits for indoor graywater systems, as specified.
