Portable and standby generators in unincorporated Riverside County must comply with Ordinance No. 847 noise limits except during declared emergencies or PSPS events. Permanent generators require building permits, and placement must meet 55 dBA day / 45 dBA night at property lines.
Generator use in Riverside County is regulated by Ordinance No. 847 (Noise) with emergency exceptions. Permanent standby generators (natural gas, propane, diesel) require a Riverside County Building & Safety permit, electrical permit, and compliance with CA Building Code Chapter 7A (wildfire). Noise from operating generators is measured at the nearest residential property line and may not exceed 55 dBA during 7 AM-10 PM or 45 dBA during 10 PM-7 AM, except during power outages, declared emergencies, PSPS (Public Safety Power Shutoff) events, or authorized testing periods (limited to 30 minutes weekly, typically during business hours). Newer enclosed/quiet generators (e.g., Generac Guardian series) rated 55-65 dBA at 23 feet can meet limits with proper setback. Portable generators used for construction on permitted jobsites are exempt during daytime hours but must not operate overnight in residential areas. Diesel generators are also subject to SCAQMD Rule 1470 and CARB emissions rules. Propane and natural gas generators have setback from windows/doors of 5-10 feet under CMC.
