Oakley FAQ
Can I run a washing machine after 10 PM?
Interior household appliances are generally fine if they are not audible from neighboring property lines. Running a washer or dryer inside a closed home typically does not violate Oakley's noise standards.
Are leaf blowers restricted?
Yes. Gas-powered leaf blower sales are banned statewide under AB 1346 effective January 2024, and Oakley restricts powered yard equipment use outside of daytime hours under OMC Chapter 8.20.
Who responds to late-night noise complaints?
Oakley contracts for police services through the Contra Costa County Sheriff's Office. Call the non-emergency line for ongoing noise disturbances after quiet hours begin.
Walnut Creek FAQ
Are weekend quiet hours different in Walnut Creek?
Quiet hours themselves are 10 PM-7 AM every day, but construction activity has stricter weekend and Sunday rules covered separately under the construction-hours ordinance.
Can I get a variance for an outdoor wedding that runs past 10 PM?
Yes. Walnut Creek issues temporary noise variances through the Community Development Department for special events; apply at least 30 days in advance and expect conditions on amplified-sound cutoff times.
