Pacifica, CA Noise Ordinances: Aircraft Noise (2026)

6a. 02 sets the general disclosure required for every residential sale in the City: that at its closest point the City is located two and one-half miles from San Francisco International Airport, that SFO is the fifth largest airport by volume in the United States and seventh largest in the world, and that the property is subject to noise from aircraft overflight. 03 layers on a special disclosure for property within the aircraft noise footprint of the FAA's 1983 CNEL Noise Exposure Map for Pacifica: that the 1983 CNEL contour area is four and one-tenths miles from SFO at its closest point, and that if the property was constructed, reconstructed or renovated after January 1, 1993 at a cost equal to twenty-five percent or more of its current market value, it must be insulated to meet FAA noise insulation program standards.

It further discloses that an owner who already received FAA noise insulation may not deliberately or willfully act to reduce or destroy the effectiveness of those noise mitigation measures. The chapter is a disclosure mandate tied to real estate transfers, not a land-use or operational restriction on aircraft or airport activity.
