Showing ordinances that apply to Cal-Nev-Ari, NV
Cal-Nev-Ari is an unincorporated community (population 144) in Clark County, Nevada. Because Cal-Nev-Ari is not an incorporated city, it does not have its own municipal code. Instead, Clark County ordinances apply directly to properties here. The hvac & mechanical noise rules below are the ones that govern your area.
Residential HVAC condensers must stay under 47 dB day and 37 dB night at the property line per Title 30. Desert 115 F heat runs AC 24/7, so compliance usually means setback or a sound blanket.
In unincorporated Clark County, HVAC condensing units, rooftop package units, and evaporative cooling equipment are treated as stationary noise sources under Title 30 Section 30.68.020. Because desert summer temperatures routinely exceed 110 F and AC runs essentially around the clock, nighttime compliance is the hardest bar: condensers must stay below 37 dB at 1000 Hz at the receiving residential property line. This typically means setting the condenser at least 5 to 10 feet from the shared wall, using a modern variable-speed compressor, and installing an acoustic blanket or block wall where the lot line is close. Commercial rooftop units on strip centers in Spring Valley, Paradise, and Enterprise that abut residential neighborhoods must also meet the 37 dB night limit because the boundary rule pulls in the stricter residential standard. Title 15 building code and the mechanical permit process are the front-line controls; Code Enforcement handles post-installation complaints. Under CCC Title 30.20 zoning setbacks, mechanical equipment cannot be placed in required side-yard setbacks on some small lots.
HVAC exceedance at property line: Title 30 Section 30.68.020 citation. Improper setback: Title 30.20 zoning violation. Repeat complaint: abatement order.
