Building standards: graywater.

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 Department of Housing and Community Development to propose to the commission the adoption, amendment, or repeal of building standards relating to hotels, motels, lodging houses, apartment houses, and dwellings, and the buildings and structures accessory thereto, except as specified. Existing law requires the Department of Housing and Community Development, at the next triennial building standards rulemaking cycle that commences on or after January 1, 2009, to adopt and submit to the commission for approval building standards for the construction, installation, and alteration of graywater, as defined, systems for indoor and outdoor uses. Existing law requires the Department of Water Resources to adopt standards for the installation of graywater systems. Existing law terminates the authority of the Department of Water Resources to adopt graywater standards for residential buildings upon the approval by the commission of the standards submitted by the Department of Housing and Community Development. This bill would require the commission, as a part of the next triennial edition of the California Building Standards Code adopted after January 1, 2011, to adopt building standards for the construction, installation, and alteration of graywater systems for indoor and outdoor uses in nonresidential occupancies, in accordance with prescribed requirements. The bill would terminate the authority of the Department of Water Resources to adopt standards for graywater systems in nonresidential occupancies upon adoption of the standards by the commission.
