Federal law preempts local aircraft noise regulation. Philadelphia is near Philadelphia International Airport (PHL) and Northeast Philadelphia Airport (PNE). The city cannot set aircraft noise limits but Phila. Code Chapter 10-400 governs general noise, and the city works with FAA on voluntary noise abatement procedures.
Philadelphia's aircraft noise regulations address the impact of airport operations on nearby residential neighborhoods. Properties within designated airport noise contours (typically 65 DNL and above) are subject to special zoning overlay districts that restrict new residential construction and require sound insulation for existing homes. The city participates in FAA Part 150 noise compatibility programs, which fund voluntary soundproofing improvements for eligible homes. Building codes in noise-affected zones require Sound Transmission Class (STC) ratings of 35 or higher for exterior walls and windows. Real estate disclosures are mandatory for properties within airport influence areas. Pennsylvania's Mid-Atlantic includes several commercial airports that generate local noise policy.
New construction without required sound insulation in airport zones carries stop-work orders and fines of $500–$2,000. Failure to provide real estate noise disclosure results in liability for rescission of sale.
