Palm Desert, CA Noise Ordinances: Decibel Limits (2026)

Section 9.24.030 sets the numeric noise ceiling in the City of Palm Desert. The limit is a ten-minute average, measured in A-weighted decibels (dBA), and the table applies by its own terms to a fixed noise source, to pool equipment under Section 25.16.110, and to leaf blowers under Section 9.24.075. In residential zones the ceiling is 55 dBA from 7 a.m. to 10 p.m. and drops to 45 dBA from 10 p.m. to 7 a.m. Public Institutional and Commercial zones both carry 65 dBA by day and 55 dBA at night. The code defines a fixed noise source as a stationary device, including pumps, fans, compressors, generators, and air conditioning and refrigeration equipment.

Two adjustments sit in the same section. If the measured ambient noise level already exceeds the applicable limit, the allowable average sound level becomes the ambient noise level. Where two zoning districts meet, the limit is measured at the higher allowable district. Section 9.24.110 puts the measurement point for residential complaints at the property line of the affected residential property, which is the address the complaint came from. Interior readings are taken inside the affected unit at a point at least four feet from the wall, ceiling or floor nearest the noise source. Readings between nonresidential properties are taken at the property line of the affected property.

Meters must meet American National Standard Institute's Standard SL. 4-1974 for type 1 or type 2 sound level meters, or provide equivalent data. Section 9.24.090 carries the zone limits into schools, hospitals and churches while they are in use. Section 9.24.100 adds eight dBA to the standards for air conditioning or refrigeration equipment installed before December 1, 1985.
