Quiet Hours
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.

Some RestrictionsAircraft Noise
Rocklin has no local ordinance regulating aircraft-in-flight noise. Aircraft operations and overflight noise are preempted by federal law (49 U.S.C. §40103 federal navigable-airspace sovereignty and §41713 airline-route/service preemption) and administered by the FAA. The nearest general-aviation field is Lincoln Regional Airport (KLHM) to the north; Sacramento International (KSMF) sits ~25 miles southwest. Rocklin's General Plan Noise Element treats aircraft as a transportation noise source subject to standard exterior land-use compatibility thresholds (60 dBA Ldn/CNEL 'normally acceptable' for residential, 60–65 dBA conditionally acceptable with mitigation) rather than imposing source-specific limits on pilots.

Few RestrictionsIndustrial Noise
Rocklin regulates industrial and stationary-source noise primarily through General Plan Noise Element compatibility standards and zoning conditions, rather than a stand-alone numerical decibel ordinance. The General Plan exterior noise standard for residential receivers is 60 dBA Ldn/CNEL 'normally acceptable' (up to 65 dBA conditionally acceptable with mitigation); industrial uses themselves are 'normally acceptable' up to 75 dBA Ldn. New industrial projects abutting residential zones must include an acoustical analysis showing compliance at the property line. Persistent stationary noise affecting neighbors is enforced as a nuisance via Code Enforcement and the Police Department.

Some RestrictionsDecibel Limits
Rocklin does not publish a single numerical decibel ordinance in its Municipal Code. Instead, noise standards are set by the General Plan Noise Element (Chapter IV.E) using California's land-use compatibility matrix: residential exterior 60 dBA Ldn/CNEL 'normally acceptable,' 60–65 dBA 'conditionally acceptable' (mitigation required), 65–70 dBA 'normally unacceptable,' >70 dBA 'clearly unacceptable.' Interior residential standard is 45 dBA Ldn (California Building Code Title 24 Part 11 §1207). Construction noise is regulated by hours (weekdays 7 a.m.–7 p.m., weekends 8 a.m.–7 p.m.) rather than dB caps. Persistent unreasonable noise is cited under Cal. Penal Code §415 and the General Plan compatibility framework.

Some RestrictionsOutdoor Music
Rocklin does not impose a stand-alone amplified-music decibel chapter. Outdoor music at private parties, restaurants, and events is governed by (1) Rocklin Municipal Code Chapter 9.40 'Disturbance Call Back Cost Recovery,' which charges responsible parties for repeat police calls to loud gatherings, (2) Cal. Penal Code §415 (disturbing the peace by loud and unreasonable noise — misdemeanor), and (3) General Plan Noise Element exterior compatibility standards (60 dBA Ldn residential 'normally acceptable'). Commercial venues with regular amplified entertainment generally require a Conditional Use Permit under Title 17 zoning, which includes site-specific noise conditions.

Some RestrictionsVehicle Noise
Vehicle noise (exhaust, muffler, modified-exhaust 'pops and bangs,' compression brakes on trucks, amplified car stereos audible from a distance) is regulated by California state law, not by a Rocklin-specific decibel chapter. Cal. Vehicle Code §27150 requires every motor vehicle to be equipped with an adequate muffler 'in constant operation' and prohibits muffler cutouts, bypasses, or similar devices. §27151 bans modifying an exhaust system to amplify noise. §27007 prohibits sound amplification from a vehicle audible at 50+ feet. Rocklin Police enforce these state-code sections; the state also sets passenger-vehicle limits at 95 dBA (CVC §27201) measured under SAE J1169 procedures.
