Summary
San Diego County encourages native and low-water plants through its Water Conservation in Landscaping Ordinance, which applies water-efficiency standards to new and renovated landscapes but does not mandate natives for existing yards.
Consistent with the Legislature's findings the purpose of this chapter is to promote the values and benefits of landscaping practices that promote the conservation and efficient use of water in a manner at least as effective as the Act and implementing Regulations.
Full Breakdown
The county's landscaping ordinance implements the state Water Conservation in Landscaping Act and is designed to be at least as effective as the state Model Water Efficient Landscape Ordinance (MWELO). It requires water-efficient design, irrigation, and plant selection on qualifying new and renovated landscape projects, favoring drought-tolerant and native species. Existing homeowners are not required to convert to natives, but rebate programs and the ordinance strongly encourage low-water, climate-appropriate planting.
Violations & Fines
Non-compliant qualifying landscape projects can be denied plan approval or a final until they meet the ordinance's water-efficiency standards.
