Redding, CA Noise Ordinances: Industrial Noise (2026)

Schedule 18.40.100-A in RMC 18.40.100(E) treats industrial receiving land use as 'n/a' inside its own district but adds a footnote: industrial noise shall be measured at the property line of any nonindustrial district. The result is that an industrial operator can be louder on its own boundary if both sides are industrial, but the moment a residential or office parcel is the receiver the residential 45 dB(A) night / 55 dB(A) day or commercial 55/65 dB(A) cap controls. Section 18.40.100(B) general nuisance also applies. RMC 18.40.110(A)(1) gives the Development Services Director authority to require a project-specific acoustical analysis for new uses that may not meet Noise Element standards, and 18.40.110(A)(2) authorizes attenuation measures including noise walls that exceed normal height and setback limits. Public-works construction by the City, County, State, or a CPUC utility is exempt under 18.40.100(H)(5), and routine public-utility facilities such as transformers, lift stations, and pumping stations are exempt under 18.40.100(H)(6).
