Powered lawn and gardening equipment in Brentwood may be operated from 7:00 AM to 7:00 PM on weekdays and Saturdays, and from 8:00 AM to 6:00 PM on Sundays and holidays. Electric and battery-powered equipment must still comply with these hours under BMC Chapter 9.32.
Brentwood Municipal Code Chapter 9.32 restricts the operation of powered landscaping equipment to reasonable daytime hours to protect residential peace. Weekday and Saturday hours are 7:00 AM to 7:00 PM. Sunday and federal holiday hours are 8:00 AM to 6:00 PM. This applies to lawn mowers, string trimmers, hedge clippers, chainsaws, wood chippers, and similar equipment, regardless of whether they are gas, electric, or battery powered. Landscape maintenance companies servicing residential neighborhoods must also comply with these hours; commercial contractors working at public facilities or HOA common areas may have slightly extended windows via service agreement but are still subject to the ordinance. Under California AB 1346, sale of new gas-powered small off-road engines (most lawn mowers and leaf blowers) ended January 1, 2024, accelerating the transition to electric equipment throughout Contra Costa County. Violations are cited by Code Enforcement, with first-offense fines of $100.
