Chino FAQ
What time do I have to turn down amplified music in Chino?
Nighttime caps under CMC § 9.40.040 start at 10:00 p.m. (drop to 50 dBA L50 / 70 dBA Lmax at property line). Loud-party rules under Ch. 9.36 apply 24/7 regardless of decibels.

Under Ord. 2019-005, up to $1,500 in a 72-hour period (warning + $250 + $500 + $750). Independent § 9.40 noise citations and state disturbing-the-peace charges may also apply.
Do the loud-party fines apply only to teenage parties?
No. Chapter 9.36 applies to any gathering on private property — adult parties, family events, large barbecues — where police are called for noise or disorder. The minor/parent provision applies only when the responsible host is under 18.
