Full Breakdown
Chapter 8.10 of the Aliso Viejo Municipal Code targets disturbances in residential areas during sleeping hours. Under section 8.10.030 it is a public nuisance to behave in violation of California Penal Code Section 407 (unlawful assembly) or 415 (disturbing the peace) in a residential area between 10:00 p.m. and 7:00 a.m., or to make noise that is unreasonably loud, raucous or jarring to persons in the residential area during quiet hours. Residential area means anywhere within 300 feet of a single-family or multifamily residence.
Section 8.10.060(C) lays out the response. On the first response the chief of police services decides whether the disturbance is a public nuisance. If it is, the chief or deputies can skip immediate arrest and instead advise the people creating the disturbance, the occupant, and the owner if present, that the disturbance violates the chapter, that arrest or citation follows unless it stops, and that additional man-hours and equipment can be charged up to $500.00. The notice is a written form titled First Response-Disturbance in Residential Area During Sleeping Hours. If a complaint comes in again at the same location that night or the next date specified, officers take action to abate immediately, including arrest or citation. Arrest remains available at any time, including on the first response.
Cost recovery follows a set path. The owner and occupant get a written invoice under section 8.10.070 in accordance with section 1.06.260. Either can protest by written request to the city manager within 10 calendar days of service, which sets a hearing before a hearing officer. If the owner does not appeal, the invoice can become a lien or special assessment on the property under section 8.10.090. Where the occupant is not the owner and has not paid within 30 calendar days after the invoice becomes final, the city can collect from either one. Section 8.10.040 exempts licensed outdoor gatherings, public dances and shows under Chapter 11.05.
Violations & Fines
Under section 8.10.050 a person who creates a nuisance defined in section 8.10.030(B) commits a misdemeanor, as does an owner or controller of property who knows of the nuisance and fails to take immediate and reasonable steps to abate it. Both are punishable under section 1.06.010(B) by a fine of not more than $1,000, imprisonment of not more than six months, or both. Section 8.10.120 makes an owner and occupant who are different people jointly and severally liable for the invoice.
