The City of Sonora sets no numeric decibel limit for stationary noise. Data-center cooling and generators are governed by the Chapter 8.20 nuisance rules and the General Plan Noise Element's land-use compatibility standards, not a dBA property-line cap like larger cities use.
Sonora's Municipal Code contains no noise chapter with numeric dBA limits. Chapter 8.20 (Nuisances) treats excessive noise as a nuisance subject to abatement and caps construction noise: powered equipment runs only 7 a.m. to 7 p.m. weekdays, 8 a.m. to 5 p.m. Saturday, and 10 a.m. to 3 p.m. Sunday and federal holidays. For continuous plant noise, the city relies on the 2004 General Plan Noise Element, which applies a land-use compatibility table (Ldn/CNEL) rather than a fixed day/night decibel limit at the property line. A data center abutting homes must satisfy those compatibility standards and the general nuisance rule.
Noise that rises to a nuisance, or construction outside the permitted hours, violates Chapter 8.20; the building official may suspend or revoke the permit, and the city can pursue abatement and penalties.
