AB 1572 bans the use of potable (drinking) water for irrigation of non-functional turfgrass in certain areas. This law applies to commercial and municipal landscapes rather than private homeowners. “Non-functional” refers to grass in median strips, islands, parking lots, and landscaped areas around commercial buildings. This also includes HOA common areas. It specifically excludes sports parks, cemeteries, and single-family homes. Most public landscapes are already irrigated with non-potable water. Purple irrigation pipes carry non-potable water (you’ve probably seen them in parks and other public areas). Since the law specifically excludes single-family homes, the average homeowner will not be affected by this law.
