Martinez FAQ
Oakley FAQ
Do I need a permit for a backyard wedding with a DJ?
Private residential events with amplified music generally do not require a permit if they end by 10 PM on weeknights or 11 PM on weekends. Larger ticketed or commercial events may need a Special Event Permit.
How is amplified sound measured?
Oakley enforcement measures sound with a dBA-weighted sound level meter at the receiving property line, not at the source. Several feet of distance and intervening structures matter significantly.
Can restaurants have outdoor live music?
Yes, but typically only under conditions attached to their conditional use permit, which may set end times (often 9 or 10 PM) and maximum dBA limits.
