Montgomery County regulates industrial and commercial noise under Chapter 31B with decibel limits at property boundaries. Industrial zones adjacent to residential areas face stricter standards. The Department of Environmental Protection conducts noise monitoring for persistent complaints.
MoCo Code Chapter 31B establishes noise standards for industrial and commercial operations, particularly where they adjoin residential zones. The county uses property-line decibel measurements to determine compliance, with lower limits applied when industrial or commercial sound crosses into residential areas. Continuous noise from HVAC systems, generators, compressors, loading docks, and manufacturing equipment must comply with both daytime and stricter nighttime standards. The Department of Environmental Protection conducts noise monitoring using calibrated equipment when chronic complaints are received. Montgomery County zoning regulations under Chapter 59 also address noise as part of conditional use approvals for industrial and commercial operations near residential zones. The I-270 technology corridor and areas around White Flint, Germantown, and Shady Grove have seen noise complaints from data centers and mixed-use developments. Maryland Environment Article Title 3 provides state-level authority that supplements county enforcement.
