Industrial zones allow 67 dB day and 57 dB night at 1000 Hz per Title 30 Section 30.68.020. M-1, M-2, M-3 zones also relax audio rules. Residential limits still control at any residential boundary.
Clark County Title 30 Section 30.68.020 establishes separate octave-band decibel caps for industrial zones. At 1000 Hz, light industrial and heavy industrial zones permit 67 dB daytime and 57 dB nighttime, measured at the property line — substantially higher than the 47 dB and 37 dB caps in residential zones. When an industrial use abuts a residential zone, the code applies the more restrictive residential limit at the shared property line, so industrial operators near homes in Sunrise Manor, Whitney, or east of Nellis must still design to the 47 and 37 dB residential thresholds. Title 12 Section 12.40.020 portable and motor vehicle audio rules do NOT apply in M-1, M-2, or M-3 industrial zones, which is why some industrial yards run outdoor PA systems without citation. Compressors, loading dock activity, refrigeration units, and rooftop equipment are all subject to the octave-band measurements. Clark County Code Enforcement inspects with calibrated sound meters for persistent complaints.
Industrial exceedance at residential boundary: Title 30 citation. Nuisance operation: Title 14 Section 14.55.020. Repeat offender: business license review.
