Non-functional Turf

Guidelines for Non-functional Turf (Decorative Lawns) in Non-Residential Landscaping

In 2023, the State of California passed AB 1572, which prohibits the use of potable water to irrigate non-functional turf on municipal, commercial, institutional and industrial properties, including HOA common areas. Non-functional turf is defined as “any turf planted within nonresidential landscapes, excluding recreational areas, and other areas where turf is necessary for the intended function of the planted area and no alternative materials are suitable for the anticipated site use.” In more basic terms, non-functional turf refers to decorative lawn maintained primarily for aesthetic reasons rather than for recreational or community activities. Turf areas watered by recycled water or well water are also excluded. With the exception of HOA common areas, residential properties are also excluded.

Compliance Timeline

The compliance period is staggered for different land ownership from 2027 to 2029 with the compliance period beginning on:

January 1, 2027 for all municipal, public agency and/or government parcels

January 1, 2028 for all other institutional, commercial and industrial properties

January 1, 2029 for all common areas of properties of homeowners’ associations.

Note: AB1572 does not require non-functional turf to be removed or replaced by a specific date, only to stop irrigation with potable water.

NMWD Resources for Non-Functional Turf

NMWD can help support our non-residential customers in meeting these new state requirements, in advance of the established timeline. Should you choose to replace the non-functional turf areas with a low water use landscape, a Cash-for-Grass rebate is currently offered that can help cover a portion of the cost of converting your lawn areas. The amount ranges from $0.50/square foot up to $1.50/square foot, with the maximum determined on a case-by-case basis and while funding is available. If you are interested in learning more about the Cash for Grass Program, please email waterconserve@nmwd.com or call 415-761-8944.
