Commercial and industrial noise in Folsom is capped at 65 dBA daytime / 55 dBA nighttime at the property line when adjoining residential zones. Commercial operations along East Bidwell, Iron Point, and the Intel campus must comply with the General Plan Noise Element and any conditional use permit limits.
Folsom Municipal Code §8.42 establishes tiered noise limits based on receiving land use: residential receives 55 dBA night / 65 dBA day; commercial receives 65/70; industrial receives 70/75. Businesses near residential (Folsom Palladio, Broadstone Marketplace, Natoma Station shopping) must meet the residential receiving standard at the shared property line. Loading dock, HVAC, refrigeration, and trash compactor noise are common complaint sources. The Folsom General Plan Noise Element (adopted per CEQA) designates the Intel Folsom campus as a special noise-compatible zone. Commercial operators receiving repeat complaints can be required to install attenuation (sound walls, equipment enclosures) as a condition of permit renewal.
Administrative citations $250-$1,000. Repeated violations can trigger CUP review and noise mitigation requirements.
