Baltimore County, MD Data Centers & Crypto Mining: Data Center Noise Limits (2026)

Section 443, adopted by Bill No. 5 Zone. 02, Maryland's environmental noise standard, and Article 17, Title 3 of the Baltimore County Code, the county's own noise ordinance chapter, as the two bodies of law that govern. G makes this section control over any conflicting zoning provision, a data center cannot rely on any other part of the zoning regulations to avoid the noise duty. The noise standard sits alongside the section's landscaping requirement in Subsection E, which requires a buffer around any data center or energy storage building that adjoins residentially zoned or used property, reinforcing that the county expects these facilities, mechanical equipment included, to be screened and quieted where they meet a residential neighbor.

5 Zone; a facility outside that zone is not governed by these noise, setback or landscaping standards and would instead need review under whatever regulations apply to its actual zoning classification.
