Summary

Rockingham County has no decibel rule for data centers specifically: its general noise ordinance bars unreasonably loud noise from any mechanical equipment or appliance, day or night.

These county ordinances apply to unincorporated areas of Rockingham County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

(a) Loud noise considered unlawful... it shall be unlawful for any person to make, permit, continue or cause to be made or to create any unreasonably loud noise in the county... (14) Appliances and other mechanical devices. The operation of any noise-producing appliance or other mechanical device which, due to operational deficiencies, malfunction or other type of disrepair, causes loud and excessive noises... as to unreasonably disturb the rest and quiet of any person of normal sensibilities on adjacent premises...

Full Breakdown

There's no data-center-specific noise standard in Rockingham County, but Sec. 18-36 reaches any noise-producing appliance or mechanical device, the category a data center's HVAC units, generators, and chillers fall into. The county judges 'unreasonably loud' by time of day, proximity to homes, whether the noise is constant, and whether it could be controlled without unreasonable cost, factors a large mechanical plant runs straight into.

Violations & Fines

First offense $100 civil penalty, $250 for a second within 12 months, $400 for a third; unpaid penalties add a $50 delinquency charge; the county may instead pursue a Class 3 misdemeanor with up to a $500 fine.

Frequently Asked Questions

Does Rockingham County have a decibel limit for data centers?
No. The county's noise ordinance uses a reasonableness test, time of day, proximity to homes, and whether the noise is constant, rather than a numeric decibel cap.
What noise sources at a data center could trigger a violation?
Generators, chillers, and HVAC equipment fall under the ordinance's 'noise-producing appliance or mechanical device' clause if they disturb nearby residents' rest or quiet.
