LA County does not have a county-wide gas leaf-blower ban, but operation is subject to the Ch. 12.08 dB limits and construction-hours rules (7 a.m.–8 p.m. weekdays).
Altadena is unincorporated, so the City of Los Angeles' gas leaf-blower ban does not apply. Leaf blowers operated within 500 feet of a residence must comply with Section 12.08.440 hour limits (7 a.m.–8 p.m. weekdays, 8 a.m.–8 p.m. Saturdays, no Sunday/holiday operation) and may not exceed the residential 50 dBA daytime / 45 dBA nighttime exterior noise standard at the property line. Statewide, CARB regulations restrict the sale of new gas-powered small off-road engines (including leaf blowers) under AB 1346 as of 2024.
Administrative citations under Chapter 1.25 — typically $100, $200, $500 escalating.
