Commercial Landscape Restrictions
AB 1572 and nonfunctional turf
California's law against watering nonfunctional grass with drinking water
Assembly Bill 1572, a change to the California Water Code initiated by the State, was signed into law October 2023 with the goal of promoting water efficiency and preserving the state’s water supply. It will soon prohibit the use of drinking water for irrigation of decorative lawns at commercial, industrial and institutional locations, including common areas within HOAs. Grass on the property of residential homes is not affected by AB 1572. Residential customers can still water their yards.

Will our community be affected?
To some extent. But the good news is almost all of the public and commercial landscape in the Irvine Ranch Water District service area — including street medians, college campuses, business complexes, and homeowners association properties — is irrigated with recycled water. Recycled water is droughtproof and not subject to the nonfunctional restriction.
What is nonfunctional turf?
Nonfunctional turf is grass that is purely aesthetic and not otherwise used for human recreation. These areas of grass are commonly found between sidewalks and streets, in front of businesses and in common areas of properties maintained by homeowners associations.
Grass areas used for recreation or civic events, such as parks, school fields and sports fields are considered functional turf and therefore not affected by AB 1572.
Who does AB 1572 apply to?
AB 1572 applies to:
- Properties owned by state and/or local governments
- Commercial, industrial and institutional (CII) properties
- Common areas of homeowners associations and common interest developments
AB 1572 does not apply to:
- Any grass or landscaping irrigated with recycled water
- Residential landscapes
- School sports fields, community parks, athletic fields and cemeteries
- Pet exercise areas
When do you have to comply with AB 1572?
Commercial properties must discontinue the use of drinking water to irrigate nonfunctional turf by the following dates.

Self-certification
CII properties with 5,000+ square feet of irrigated turf must self-certify to the State Water Resources Control Board that their property is in compliance every three years beginning June 30, 2030. HOA properties with 5,000+ square feet of irrigated area must self-certify that their property is in compliance every three years beginning June 30, 2031. The self-certification process has not yet been developed by the State Water Resources Control Board. Check back for updates!
