HVAC condensers, heat pumps, and pool equipment in Alameda County must not exceed residential decibel limits at neighboring property lines: 60 dBA daytime and 50 dBA nighttime. Setback and screening are required for new installations.
Alameda County building and planning codes require HVAC equipment to meet the Noise Element exterior limits at adjoining property lines. Most residential HVAC condensers produce 55 to 75 dBA at one meter, so setback, barrier walls, or sound blankets are often needed to meet the 50 dBA nighttime standard three to five feet into a neighbor property. Pool pumps, variable refrigerant flow systems, and whole-house fans fall under the same standards. New construction reviews require specification sheets showing sound ratings (dBA at three feet) and a site plan showing distance to nearest receiver. The California Green Building Code (CALGreen) and Title 24 Part 6 influence placement requirements. Retroactive enforcement against existing equipment relies on complaint-based measurements.
