Commercial operations in unincorporated Sacramento County must keep noise at adjacent residential property lines below 55 dBA day and 50 dBA night. Industrial zones along Power Inn and Florin-Perkins allow higher thresholds.
Chapter 6.68 sets receiving-land-use limits rather than source limits, so a commercial site adjacent to residential zoning must meet the residential threshold at the shared line. Conditional use permits typically include stricter operational conditions: loading-dock hours, HVAC enclosure, and refrigerated-trailer idling limits. Industrial corridors (M-1, M-2) along Power Inn, Florin-Perkins, and near McClellan Business Park allow 70 dBA daytime. SMAQMD also regulates stationary-engine noise alongside air permits.
Administrative citation 250 to 1,000 dollars per day; permit conditions can be revoked.
