Full Breakdown
Chino Municipal Code § 9.40.060(E) exempts certain noise sources from the chapter's general dBA standards only if they stay inside set hours. Subsection (E)(4) covers 'noise sources associated with the maintenance of real property', lawn and garden equipment, pressure washers and similar residential upkeep tools, and confines that noise to 'seven a.m. to eight p.m. on any day except Sunday, or between the hours of nine a.m. and eight p.m. on Sunday.' Maintenance noise outside those windows loses the exemption and is measured against the ordinary Zone I exterior noise limits. Adopted by Ord. 95-10 § 1 (part), 1995; amended by Ord. 2004-23 § 59, 2004.
Violations & Fines
Property-maintenance noise outside the permitted hours forfeits the exemption and is judged against the standard dBA limits; a violation is a misdemeanor punishable by a council-set fine, up to six months in jail, or both.
