Riverside, CA Landscaping Rules: Artificial Turf (2026)

Riverside allows artificial turf in residential front and rear yards as part of its water-conservation-friendly landscape code. Synthetic turf must be a high-quality, UV-stabilized product with a permeable backing that allows rainwater infiltration; indoor-outdoor carpet and low-grade products are prohibited. Typical City standards require proper base preparation (compacted aggregate), infill (often silica sand or coated alternatives), edging to contain the material, and a realistic appearance with multi-tone fibers. Turf must be kept clean, free of tears, seams secured, and replaced when it becomes matted or faded. Use in the street parkway (between sidewalk and curb) is generally discouraged in newer developments because it can overheat and does not absorb stormwater as effectively as plantings; some overlay zones and specific plans prohibit it there entirely. California Civil Code section 4735 prohibits homeowners associations from banning artificial turf outright, though HOAs may impose reasonable installation and aesthetic standards (quality grade, seam tolerances, colors). Permits are generally not required for a simple residential turf installation, but projects that include grading over 50 cubic yards, retaining walls, or irrigation modifications may require permits. RPU has offered rebates for turf replacement that include synthetic grass (though recent programs have emphasized living low-water landscapes over artificial turf). Homeowners should check heat reflectivity before installing turf near playsets or pets, as surface temperatures can exceed 150°F in Riverside summers.
