Summary
San Joaquin County unincorporated areas limit leaf blower operation to construction-hour windows under Development Title §9-1015. California AB 1346 bans the sale of new gas-powered small off-road engines (including leaf blowers) effective January 1, 2024, enforced by CARB. SJVAPCD Spare the Air advisories discourage gas blower use on high-pollution days, and ag operations in unincorporated county are generally exempt under the Right to Farm Act (Civil Code §3482.5).
Small off-road engines (SORE), which are used primarily in lawn and garden equipment, emit high levels of air pollutants, including oxides of nitrogen (NOx), reactive organic gases (ROG), and particulate matter (PM). NOx and ROG together contribute to formation of ozone, a criteria pollutant with a national ambient air quality standard set by the United States Environmental Protection Agency (U.S. EPA) and a California ambient air quality standard and that has adverse impacts on health. Currently, California exceeds U.S. EPA and state standards for ozone in many areas, including the South Coast Air Basin, the San Francisco Bay area, and the County of Sacramento.
Full Breakdown
San Joaquin County Development Title (Title 9) noise provisions limit leaf blower operation in residential zones to the same window allowed for construction equipment, generally 7:00 AM to 7:00 PM weekdays and 8:00 AM to 6:00 PM Saturdays, with no Sunday or holiday use. Statewide, California AB 1346 (2021) directed CARB to prohibit the sale of new gas-powered small off-road engines (SORE), which took effect January 1, 2024, existing gas blowers may still be used but replacement units must be zero-emission. The San Joaquin Valley Air Pollution Control District (SJVAPCD) routinely issues wintertime air advisories that ask residents to avoid gas-powered yard equipment. Agricultural operations on parcels zoned AG or AU are generally exempt from residential noise limits under the Right to Farm Act (Civil Code §3482.5) as adopted in county ordinance. Cities inside the county (Stockton, Lodi, Manteca, Tracy) set their own blower hours and several have tighter windows.
Violations & Fines
Operating outside allowed hours in unincorporated residential zones: $100 first offense, $200 second, $500 third within 12 months. Sale of new non-compliant gas SORE units: CARB civil penalties up to $5,000 per unit. Use during a Spare the Air advisory is voluntary, not penalty-backed.
