Hamilton County sets no industrial-noise standard. Municipal zoning codes and township resolutions govern factory and business noise. Cincinnati caps manufacturing-district noise at 75 dB(A) daytime and 70 dB(A) at night at the receiving property line.
The county does not regulate industrial or commercial noise. Cincinnati's Chapter 909 applies dB(A) limits by receiving zoning district: manufacturing-zoned property may reach 75 dB(A) daytime (7 a.m.–7 p.m.) and 70 dB(A) at night, measured Leq over six minutes at the affected boundary. Townships may adopt noise resolutions under ORC 505.172 reaching businesses and industries regardless of when they were established, though activities like agriculture, coal and surface mining, and oil and gas operations are statutorily exempt. Industrial operators should check the specific city or township standard applicable at their site.
Cincinnati industrial-noise breaches are prima facie loud-noise violations (minor misdemeanor). Township violations under ORC 505.172 are misdemeanors of the second degree, with fines paid into the township general fund.
