The exterior noise limits drop 5 dB at 10:00 p.m. and return to daytime levels at 7:00 a.m. (CMC § 9.40.040). At night, anything louder than 50 dBA L50 or 70 dBA Lmax at your property line is a violation.
How loud can a neighbor be during the day?
Up to 55 dBA L50 / 70 dBA L02 / 75 dBA Lmax measured at your residential property line between 7 a.m. and 10 p.m. Short loud peaks above 75 dBA are violations any time of day.
