Summary
Rancho Cordova's own noise ordinance, Municipal Code Chapter 6.68, caps exterior noise at a residential property line at 55 dBA daytime (7 a.m.-10 p.m.) and 50 dBA overnight (10 p.m.-7 a.m.). A separate section limits stationary cooling towers, compressors, and fans to 55 dBA at that line.
Equipment installed five years after July 1, 1976, must comply with a maximum limit of 55 dBA at any point at least one foot inside the property line of the affected residential property and three to five feet above ground level.
Full Breakdown
The city adopted its own Noise Control ordinance, RCMC Chapter 6.68, separate from Sacramento County. Section 6.68.070 sets the exterior standard measured at least one foot inside the affected residential property line: 55 dBA from 7 a.m. to 10 p.m. and 50 dBA from 10 p.m. to 7 a.m. Section 6.68.120 directly targets a data center's mechanical plant - stationary cooling towers, compressors, pumps, fans, and air-conditioning apparatus - capping modern equipment at 55 dBA at the residential property line. Limits drop 5 dBA for pure-tone or impulsive noise. Violations are an infraction after written notice.
Violations & Fines
Noise over the Chapter 6.68 limits is an infraction; a mechanical-equipment violation under Section 6.68.120 carries fines up to $50, $100, then $250 after written notice to correct.
