Nonfunctional Turf: What to Know (Assembly Bill (AB) 1572)

State legislation AB 1572, signed on October 13, 2023, prohibits the use of drinking (potable) water to irrigate nonfunctional turfgrass on commercial, industrial, institutional (CII) properties and Homeowners Association (HOA) common areas throughout the state of California. AB 1572 applies to properties owned by state and local public agencies, privately-owned CII properties, and non-residential HOA common areas.

What is Nonfunctional Turf?
Nonfunctional turfgrass is defined as any turfgrass area that is maintained for decorative or aesthetic purposes and serves no other function. Examples of nonfunctional turfgrass include, but are not limited to, lawn grass on road medians, parkways, business parks, and parking lots. Turfgrass areas may be considered nonfunctional regardless of whether they have fencing.

What is Functional Turf?
Functional turf includes areas used for recreation or community spaces, such as sports fields, school fields, and picnic areas. This regulation does not apply to residential lawns or areas irrigated with non-potable, i.e., recycled/reclaimed, water. Cemeteries are exempt from the regulation.

Do I need to remove my turfgrass?
The regulation bans the irrigation of nonfunctional turfgrass (if the irrigation system is not using recycled water) and does not mandate turfgrass removal. However, replacing turfgrass with a waterwise landscape is one way to maintain green space on your property while complying with AB 1572.

Where can I find more information?
