Construction hours in Loudoun County, VA — sometimes called construction noise rules or contractor work-hour ordinances — set when contractors can run power tools, hammers, and heavy equipment.
Loudoun County restricts construction noise to 7 AM to 9 PM weekdays and 9 AM to 9 PM weekends/holidays under Chapter 684. Data center construction in Ashburn follows same rules but with frequent variances.
Loudoun County's noise ordinance limits audible construction activity generally to 7 AM to 9 PM Monday through Friday and 9 AM to 9 PM on weekends and legal holidays. Emergency utility work (Dominion Energy, NOVEC, Loudoun Water, Washington Gas) is exempt. Construction in the Data Center Alley (Ashburn/Route 28 corridor) follows the same residential-adjacent limits but large commercial projects often obtain Board of Supervisors-approved variances. VDOT roadwork on Routes 7, 15, 28, 50, 267 (Dulles Greenway/Toll Road) follows state timing rules and is county-exempt. Town of Leesburg has separate construction noise provisions with 7 AM weekday start.
Civil penalty $100 for first offense, $250 second offense, up to $500 for repeat violations within 12 months. Stop-work orders issued by Building & Development for egregious violations. Data center contractors face scrutiny given concentration in Ashburn.
