Quiet hours in Rocklin, CA — also called the noise ordinance, nighttime noise rules, or residential quiet time — define the hours during which excessive noise is prohibited.
Rocklin's General Plan Noise Element treats 7 a.m. to 10 p.m. as daytime and 10 p.m. to 7 a.m. as nighttime, with stationary sources held to roughly 55 dBA Leq during the day and 45 dBA Leq at night at sensitive receptors. Loud and unreasonable noise that disturbs the peace is enforceable as a 'disturbance' under Rocklin Municipal Code Chapter 9.40, which lets the city recover police call-back costs after a first warning.
Rocklin does not publish a stand-alone decibel ordinance, but the City of Rocklin General Plan Noise Element (1991) establishes 60 dBA Ldn as the exterior and 45 dBA Ldn as the interior community-noise standard for single-family and duplex residential land uses, with multifamily and lodging permitted up to 65 dBA Ldn exterior. For short-term stationary sources (parties, HVAC, generators, equipment), the City applies hourly performance standards of 55 dBA Leq during daytime hours (7 a.m. to 10 p.m.) and 45 dBA Leq during nighttime hours (10 p.m. to 7 a.m.), as documented in Rocklin Project EIR noise sections citing the General Plan. Under Rocklin Municipal Code Chapter 9.40 (Disturbance Call Back Cost Recovery), Title 9 Public Peace, Morals and Welfare, a 'disturbance' is any party, gathering, or activity causing 'loud and unreasonable noise so as to constitute a threat to the peace, health, safety, or general welfare of the public'; after a first response the city may issue an administrative citation and bill the responsible parties for the cost of a second police response within a specified period. California Penal Code section 415 also makes disturbing the peace through loud and unreasonable noise a misdemeanor statewide.
First police response under Chapter 9.40 generally results in a warning; a repeat response at the same address within the cost-recovery period can trigger call-back cost recovery billed to the responsible parties plus an administrative citation, with continuing or willful violations chargeable as a misdemeanor under California Penal Code 415.
