HVAC equipment in unincorporated Riverside County must comply with Ordinance No. 847 noise limits — typically 55 dBA daytime and 45 dBA nighttime at the nearest residential property line. CA Building Energy Code (Title 24) also regulates placement to minimize noise.
Residential and commercial HVAC units in unincorporated Riverside County are regulated under Ordinance No. 847 (Noise Control). Noise measured at the nearest residential property line may not exceed 55 dBA between 7 AM and 10 PM or 45 dBA between 10 PM and 7 AM. These limits apply to compressors, condensers, pool pumps, pool heaters, and rooftop packaged units. Enforcement is complaint-driven through Code Enforcement using calibrated sound-level meters. Typical central AC condensers are rated 60-75 dBA at 3 feet, meaning they often exceed residential nighttime limits if installed directly adjacent to a neighbor's bedroom. Mitigation strategies include relocating equipment to side or rear yards away from property lines, installing acoustic fencing or enclosures (minimum 1-inch MDF with absorption), mounting on isolation pads, and upgrading to quieter variable-speed models (many rated 55 dBA or less). California Title 24 Energy Code requires HVAC permits and inspection, and placement must also meet setback from property lines for safety clearances (typically 3 feet). Ductwork in attics must meet insulation and leakage standards. Repeat violations may result in abatement orders requiring relocation or sound enclosures.
Specific penalty amounts for this ordinance are not published in a publicly accessible fine schedule. Contact Riverside County code enforcement directly for current fines, enforcement procedures, and hearing options.
