Maple Grove, MN Noise Ordinances: Industrial Noise (2026)

Industrial and commercial facility noise in Minnesota is primarily a state matter. The MPCA enforces the receiver-based noise standard in Minn. R. 7030.0040 at facilities for which it issues an air-quality permit, and works with local governments on others. The key feature is that the limit follows the land use of the listener, not the source: noise from an industrial plant audible at a residence is held to the residential NAC 1 limits (L10 = 65 / L50 = 60 dBA day; L10 = 55 / L50 = 50 dBA night), while at an industrial receiver location the NAC 3 limits apply (L10 = 80 / L50 = 75 dBA day and night). Minn. R. 7030.0030 also requires municipalities with land-use authority — including Maple Grove — to take reasonable measures to prevent approving land uses that would immediately violate the state standard, which the city addresses through its zoning and planning review. Maple Grove's own City Code supplements this with its Chapter 20 noise sections (20-81 to 20-91) for local nuisance enforcement, and with the general public-nuisance provisions in §§ 14-31 and 14-32 (which also list dense smoke, fumes, and offensive conditions). To report ongoing industrial noise, residents can contact the MPCA (651-296-6300 in the metro) or the city.
