Fontana, CA Landscaping Rules: Native Plants (2026)

Fontana homeowners have broad state-law protection when converting lawns to native or drought-tolerant plants. California Civil Code 4735 voids any HOA rule that prohibits low-water-use plants, artificial turf approved for residential use, or similar water-efficient landscape features during a declared drought emergency. 7 similarly prevents local governments from restricting water-efficient landscaping. That means Fontana residents may replace turf with California-native species such as Cleveland sage, California buckwheat, deergrass, toyon, or coast live oak, with no special permit needed. The state Model Water Efficient Landscape Ordinance, adopted by Fontana through the California Code of Regulations Title 23 and Municipal Code Title 30, applies to new and rehabilitated commercial, institutional, and large residential landscapes (typically over 2,500 square feet for residential projects with a permit).

MWELO requires a Maximum Applied Water Allowance calculation, hydrozoning of plants by water need, smart irrigation controllers, and a certificate of completion signed by a licensed landscape professional. Small homeowner yard makeovers without plans or permits are exempt. Fontana Water Company and Metropolitan Water District often run turf replacement rebates (SoCal WaterSmart) that pay per square foot for converting lawn to drought-tolerant landscaping - check the program before beginning work to qualify.
