Rancho Cucamonga Environmental Rules: Gas Leaf Blower Ban Rules (2026)

Assembly Bill 1346 prohibits the sale of new small off-road engines under 25 horsepower, including leaf blowers, lawn mowers, chainsaws, and trimmers. Existing equipment may continue to be used. Operators in unincorporated San Bernardino County remain subject to general noise standards and construction-hour limits. Some incorporated cities such as Redlands and Claremont impose stricter operating hours or partial bans within city limits. Landscapers should plan to transition to battery or electric equipment as gas inventory phases out at California retailers.
