California Assembly Bill (AB) 1572 is a statewide law that prohibits the use of potable (drinking) water to irrigate nonfunctional turf at certain commercial, industrial and institutional (CII) properties beginning January 1, 2027. The law is intended to improve long-term water efficiency by eliminating the irrigation of ornamental grass that is not regularly used for recreation or other functional purposes.
