Lake Forest, CA Landscaping Rules: Native Plants (2026)

Lake Forest does not require homeowners to plant a specific list of native species in an ordinary yard, but its development code strongly steers landscaping toward water-efficient, climate-appropriate plants. New and rehabilitated landscape projects are subject to the City's Water-Efficient Landscape regulations in Section 9.146.110, which the City has adopted as an alternative that is at least as effective as the state Model Water Efficient Landscape Ordinance (MWELO). MWELO directs plant selection toward climate-adapted species suited to the site's conditions and discourages high-water-use plants, with native and drought-tolerant species favored. The City's zoning code also requires that front yard areas be landscaped with at least 50 percent live vegetation, artificial turf, drought-tolerant landscaping, or a combination of the three, and that any street-side yard on a corner lot visible from the public right-of-way meet the same 50 percent standard. In its own medians and parkways the City has been replacing turf with California-friendly native plants and drought-tolerant species. Residents selecting plants can use the state's WUCOLS (Water Use Classification of Landscape Species) database and the El Toro Water District Demonstration Garden in Lake Forest, which showcases California-friendly and drought-tolerant landscaping for the local climate. Native, fire-resistant plantings near homes also support OCFA fuel-modification and defensible-space goals.
