Leaf Blower Rules

Fontana has no local ban on gas-powered leaf blowers, but operation is limited by Chapter 18 nuisance rules and by South Coast AQMD air-quality advisories. California AB 1346 phased out sales of new gas small off-road engines starting in 2024, though using existing equipment remains legal.

This is not one of those rules that cities tend to ignore. Fontana actively enforces its leaf blower rules requirements.
