Water restrictions in Fontana, CA — also called the watering schedule, outdoor irrigation rules, or drought ordinance — set which days and hours you can run sprinklers or irrigation.
Fontana Water Company bans irrigation between 9 a.m. and 6 p.m. and any runoff onto streets. AB 1572 ends non-functional turf irrigation at commercial and HOA sites by 2027.
Drinking water in Fontana is supplied by Fontana Water Company, a subsidiary of San Gabriel Valley Water Company regulated by the California Public Utilities Commission. All customers are subject to the statewide Emergency Conservation Regulation adopted by the State Water Resources Control Board, which bans outdoor irrigation of ornamental turf during and within 48 hours of measurable rainfall, prohibits watering that causes runoff onto sidewalks, driveways, and streets, and requires shutoff nozzles on hand-held hoses. Local rules further prohibit watering landscapes between 9 a.m. and 6 p.m. when evaporation is highest. During declared drought stages, Fontana Water Company may restrict watering to assigned days by address (for example, odd-numbered houses on Tuesday, Thursday, Saturday and even-numbered houses on Wednesday, Friday, Sunday) and cap minutes-per-station. Assembly Bill 1572, signed in 2023, phases in a statewide ban on using potable water to irrigate non-functional turf at commercial, industrial, institutional, and HOA common-area properties starting in 2027; residential front lawns are not yet covered. Violations of Fontana Water Company restrictions draw escalating fines - a warning, then 50 dollars, then 100 dollars, and eventually flow-restriction devices for repeat offenders. Report water waste through the water company customer service line or the online complaint form.
