Rocklin, CA Noise Ordinances: Quiet Hours (2026)

Rocklin's general nighttime noise curfew for homes is Section 9.52.030(B)(2) of the Rocklin Municipal Code, part of Chapter 9.52 adopted by the Rocklin City Council under Ordinance No. 1197 on January 27, 2026. It restricts miscellaneous activities at residential structures, including but not limited to automotive repair, furniture construction, repair or refinishing, and amplified sound, from generating any discernable noise, meaning noise detectable by an unaided human ear that can be traced to its source, at the property line of the source residence outside 7:00 a.m. to 9:00 p.m. on weekdays and 8:00 a.m. to 9:00 p.m. on weekends.

This sits alongside two related standards in the same section: landscape maintenance activity within 100 feet of a home is held to the identical 7 a.m./9 p.m. weekday and 8 a.m./9 p.m. weekend windows under subsection (B)(1), and outdoor amplified sound in commercially zoned areas gets a later 10:00 p.m. cutoff under subsection (B)(3). Several categories are carved out entirely: emergency response activity, permitted commercial and residential alarms, school and daycare activities, city-permitted parades and events, activity on public property such as Quarry Park, utility and solid-waste crews on duty, railroads, freeways, highways and aircraft operations, organized sports, and single-family emergency generators and pumps are all exempt under Section 9.52.050.

The Community Development Director may also grant a case-by-case exception under Section 9.52.050(J) where strict compliance is infeasible or impractical, and interprets any standard the chapter does not clearly define under Section 9.52.060.
