Water Efficient Landscape Regulations

Learn about the City of San Luis Obispo’s Water Efficient Landscape Regulations.

Did you know California requires new development to have specific landscaping standards? 

The State of California has required that every California county and city adopt a water-efficient landscape ordinance that is at least as effective as the state’s model ordinance.

The California law applies to any single-family or multi-family residential, public, institutional, or commercial project that requires a permit, plan check or design review and meets one of the following size thresholds:

• New construction projects with a total landscape area greater than 500 sq ft
• Rehabilitations of existing landscape with a total landscape of greater than 2,500 sq ft

City Landscape Regulations

The City of San Luis Obispo has drafted an update to the Municipal Code which addresses Water Efficient Landscape Standards and will serve as the City’s Landscape Ordinance.

The City reviews and approves all landscaping to ensure it is consistent with state water use regulations. 

Detailed design criteria will be provided in the City Engineering Standards Uniform Design Criteria for Landscaping and Irrigation.

Benefits of Water Efficient Landscapes

The Water Efficient Landscape Regulations provide benefits beyond water savings.
