Full Breakdown
County Code Chapter 9.60 makes it unlawful to hold a gathering that substantially disturbs a neighborhood's quiet enjoyment through excessive noise, traffic, public drunkenness, underage drinking, fights, or litter. After the Sheriff posts or mails a nuisance notice, anyone liable, owner, resident, sponsor, or attendee causing the nuisance, is jointly and severally liable for full response costs if the Sheriff returns to the same premises within 60 days.
Violations & Fines
First response draws a posted/mailed notice only. A second response within 60 days bills all liable parties for the Sheriff's actual response costs; unpaid bills add a $100 penalty plus interest, and removing the required notice adds a separate $100 penalty.
