Las Vegas, NV Noise Ordinances: Decibel Limits (2026)

Las Vegas noise enforcement uses a two-track approach. For subjective complaints — barking dogs, amplified music, parties — the plainly-audible standard in LVMC 9.16 is applied. For objective measurements — industrial operations, construction equipment, HVAC — officers use a sound level meter and compare to the zoning performance-standard caps: 55 dBA nighttime (10 p.m.–7 a.m.) and 65 dBA daytime at the boundary of a residential receiving zone. Commercial receiving zones tolerate higher numbers, and industrial-to-industrial boundaries have effectively no cap beyond the general nuisance clause. Penalties for tonal content (a distinct whine or hum) or impulsive content (hammering, dropping steel) generally subtract 5 dBA from the measured reading. Complainants should remember that the reading is taken at their property line, not at the source, so intervening walls, distance and desert topography matter. The Strip and unincorporated Clark County use a separate resort-corridor standard administered by Clark County Code Enforcement.
