South Tahoe Utility District Bans Non-Functional Turf Irrigation

New state law requires businesses to replace ornamental grass with water-wise landscaping

Apr. 5, 2026 at 4:08am

The South Tahoe Public Utility District (STPUD) has updated its water conservation ordinance to comply with a new California law banning the use of potable (drinking) water to irrigate non-functional turf at commercial, industrial, and institutional properties. The ban will be phased in over the next few years, starting with government properties in 2027 and expanding to businesses and multi-family developments by 2029.

Why it matters

This law aims to reduce water usage in California, which has faced severe droughts in recent years. By targeting non-essential grass, the state hopes to conserve limited water supplies while still allowing recreational and community green spaces. STPUD is working to help local businesses and property owners comply through free site assessments and a turf buy-back program.

The details

The new STPUD ordinance prohibits watering non-functional turf, defined as purely ornamental grass that is not used for recreation or community purposes. This includes grass in medians, around office buildings, and in parking lots. The ban will be implemented in phases, starting with state and local government properties on January 1, 2027, then expanding to commercial, industrial, and institutional properties on January 1, 2028, and finally to HOA common areas, mobile home parks, apartments, and other common interest developments on January 1, 2029. Single-family homes, cemeteries, and recreational spaces like parks and sports fields are exempt from the ban.

  • The STPUD Board of Directors adopted the updated water conservation ordinance on April 2, 2026.
  • The ban on using potable water to irrigate non-functional turf at state and local government properties takes effect on January 1, 2027.
  • The ban expands to commercial, industrial, and institutional properties on January 1, 2028.
  • The ban further expands to HOA common areas, mobile home parks, apartments, and other common interest developments on January 1, 2029.
