Industrial and commercial noise in Baltimore County is governed by Maryland COMAR 26.02.03, measured at the receiving property. If the neighbor is residential, the limit is 65 dBA daytime and 55 dBA nighttime, even for a factory or plant next door.
Baltimore County relies on Maryland's statewide industrial-noise rule, COMAR 26.02.03.02, which sets maximum allowable noise by the zone of the property receiving the sound, not the source. An industrial site bordering homes is measured against the residential limit (65 dBA day, 55 dBA night) at the residential property line, not the industrial 75 dBA figure. Prominent discrete tones and periodic noises face a limit 5 dBA lower than the table value. The Maryland Department of the Environment administers industrial-noise enforcement and abatement.
The Maryland Department of the Environment can issue abatement orders and penalties for exceeding COMAR industrial-noise limits.
