Los Angeles County
South Gate has no city-specific gas-leaf-blower ban. Leaf blowers, mowers, and edgers are regulated through SGMC Chapter 11.34 (Noise Control Program), which limits on-property equipment noise by zone and time of day, plus the general 'offensive portable noise' standard in §7.44.020.02(a) for landscaping crews working on private property. Statewide, California Assembly Bill 1346 (2021) bans the sale of new gas-powered small off-road engines (SORE), including most consumer leaf blowers and lawnmowers, starting in 2024 under CARB rulemaking — but use of existing equipment remains legal.

Altadena FAQ
Are gas leaf blowers banned in Altadena?
Not at the county level. LA County restricts hours and noise but does not ban gas leaf blowers in unincorporated areas.
South Gate FAQ
Can I still buy a gas leaf blower in California?
Not new — CARB's Small Off-Road Engine (SORE) regulation, adopted under AB 1346 (Cal. Health & Safety Code §43018.11), prohibits the sale of new gas-powered SORE equipment under 25 hp for model year 2024 and later. Used equipment can still be bought and sold, and you can continue using a gas blower you already own.
Does South Gate ban gas leaf blowers outright?
No. South Gate has not adopted a use ban like Los Angeles City's older blower ordinance. The city regulates leaf-blower noise through Chapter 11.34 Noise Control Program — limits depend on the zone, time of day, and measured decibel level.
What time can my gardener start mowing on a Saturday?
Allowed start times are set in Chapter 11.34. South Gate's general code framework follows the residential-zone decibel limits in Chapter 11.34. Confirm the current Saturday and Sunday windows with South Gate Code Enforcement before instructing a crew to start before 8 a.m.
