Douglas County's Section 17A excludes general commercial use and commercial activity from its noise limits, and oil-and-gas and regulated utilities are also exempt. However, electronic amplifier noise in business and industrial districts is capped at 55 dB(A).
Section 1704A.03 excludes 'the commercial use of property and commercial activity' from the maximum permissible noise levels, and Sections 1704A.06-07 exempt regulated public utilities (Title 40) and oil-and-gas production (Article 60, Title 34). This means routine industrial operations are generally not measured against the residential decibel table. The one specific cap that does apply is Section 1703A.04, which limits any electronic amplifier to 55 dB(A) in the B, C, LI (Light Industrial) and GI (General Industrial) districts. Site-specific noise conditions are more often imposed through zoning, special-use permits, and planned-development standards.
Amplifier noise over 55 dB(A) in B/C/LI/GI districts, or breach of a permit noise condition, is a Zoning Resolution enforcement matter.
