Fountain Valley, CA Invasive Plant Rules: Front Yard Gardens (2026)

What can go in a front yard in the City of Fountain Valley is set by the landscaping chapter of the Development Code, Chapter 21.20. Section 21.20.040(b), for single-family subdivisions, requires all areas between the front of the residence and the front property line to be landscaped within six months of issuance of the certificate of occupancy or three months from the recorded sale, whichever is earlier. All single-family designated property must keep a minimum of fifty percent of the front yard setback as landscaping.

What counts as landscaping is defined in the same subsection: live plant materials, synthetic turf meeting the criteria of § 21.20.070, or other materials in a limited amount as provided in § 21.20.050(b)(2)(A). That cross-reference caps pervious materials such as crushed rock, mulch, pebbles, stone and decorative pavers at twenty percent of the required landscaping. Ground cover and shrubs counted toward a residential front yard requirement must be planted at a spacing that gives full coverage of the live landscape requirement within eighteen months of planting, apart from that limited pervious material.

A vegetable or flower garden made of live plants therefore fits the requirement. The code text quoted here contains no list of banned invasive species, so the operative front yard test is coverage, materials and maintenance. Under § 21.20.050(a)(4), landscaping must be continuously maintained free of weeds, debris, litter and temporary signage, and § 21.20.060 requires dead, diseased or hazardous trees, weeds and debris to be removed and failed plantings replaced.

A homeowner who installs the front yard alone does not need city approval of the plan: § 21.20.040(b) states that if installed by the individual homeowner, landscape plans do not require city approval. Developer-installed plans must comply with § 21.20.050(a). The turf, live groundcover and synthetic turf share of required single-family landscaping is limited by § 21.20.050(a)(6).
