Summary
New homes near Fullerton Municipal Airport's noise contours must meet 45/65-decibel CNEL limits and submit a professional acoustical analysis before Buena Park will approve occupancy.
For any residential development within a sixty-five-decibels CNEL contour, or within either the moderate noise impact area or the significant noise impact area of the Fullerton Municipal Airport as shown in the noise element of the Buena Park General Plan, an analysis by a professional mechanical or acoustical engineer shall demonstrate that the required noise levels will be achieved. Prior to issuing a certificate of occupancy, the Building Official may require tests by a qualified acoustical technician to confirm that the noise reduction achieved is sufficient to meet the requirements of this section.
B. Air Conditioning Equipment. Exterior air conditioning equipment, other than self-contained window-mounted units in single-family dwellings, shall have a sound rating number (SRN) no greater than 60 decibels, in accordance with ARI (Air Conditioning and Refrigeration Institute) Standard 270, or the equivalent. (Ord. 1754, 6/24/2025)
Full Breakdown
Because Buena Park sits under Fullerton Municipal Airport's flight paths, its zoning code requires new residential development to meet interior and exterior noise limits, 45 decibels CNEL inside main buildings, 65 decibels CNEL in outdoor living areas, and mandates a professional acoustical analysis for any project within a 60 or 65 decibel CNEL contour, or within the airport's moderate or significant noise impact area shown in the General Plan's noise element. Projects that penetrate the airport's FAA notification surface must also file FAA Form 7460-1 and forward the FAA's determination to the city and the Airport Land Use Commission.
Violations & Fines
Failing to submit the required acoustical analysis, or exceeding the 45/65-decibel CNEL limits, can hold up a certificate of occupancy until a qualified acoustical technician confirms compliance.
