Does Washoe County have a noise ordinance for construction sites?

Washoe County does not have a noise ordinance that restricts works hours for construction sites. 

CH110 Article 414 Noise and Lighting (page 340)


WCC Ch110 Article 414 states that noise thresholds may not exceed a certain decibel  level for a 24 hour period.  The code highlighted below is an exemption to WCC, meaning that temporary construction sites are exempt from this 24 hour period during the hours of 7am and 7pm.  This is not the construction site’s working hours, but the 12 hour period which they are exempt from the 24 hour period which a sound reading would be taken.


Section 110.414.10 Measurement. Measurement of sound levels shall be in accordance with

the provisions of this section.

(c) Timing and Number of Measurements. A twenty-four (24) hour measurement

shall be taken. The sound level shall be the average of the hourly readings with

the Ldn or day-night average sound level weighting.

regulations of this article:
