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.
