Lake Forest, CA Landscaping Rules: Artificial Turf (2026)

Unlike many cities that restrict synthetic lawns, Lake Forest's Water-Efficient Landscape regulations treat artificial or synthetic turf as an appropriate substitute for natural turf for water-conservation purposes. The municipal code provides that the installation and maintenance of artificial turf shall be governed by Guidelines adopted as set forth in Section 18.14.100, so a homeowner installing synthetic turf must follow the City's adopted artificial-turf guidelines (covering matters such as quality, drainage, and maintenance) rather than meeting a separate plant-water budget. Artificial turf also counts toward the City's front-yard landscaping requirement: front yard areas must be landscaped with at least 50 percent live vegetation, artificial turf, drought-tolerant landscaping, or a combination of the three, and the same standard applies to street-side yards on corner lots visible from the public right-of-way. This means a property owner can satisfy the front-yard standard with synthetic turf, live plants, drought-tolerant landscaping, or a mix. The City itself has installed artificial turf and California-friendly native plants in place of water-using turf in some of its landscaped areas. Under the statewide MWELO, artificial turf is treated as a non-irrigated, non-plant surface, so it does not draw irrigation water or trigger a plant-water-budget calculation - reinforcing why the City accepts it as a water-saving option.
