Full Breakdown
Citrus Heights sets its noise rules in Municipal Code Chapter 34, Article III. Section 34-91 governs stationary mechanical equipment - naming cooling towers, compressors, pumps, fans, and air conditioning - and caps post-1976 installations at 60 dBA measured one foot inside the affected residential property line. The general exterior standard, Section 34-86, protects residential noise areas at 55 dBA from 7 a.m. to 10 p.m. and 50 dBA from 10 p.m. to 7 a.m. These limits target residential receivers; the code sets no separate industrial-zone dBA cap. A data center's chillers and generators near homes must meet the 60 dBA mechanical limit.
Violations & Fines
Noise over the Sec. 34-91 or Sec. 34-86 limits is a code violation and public nuisance enforced by the city through citations, abatement, and permit conditions.
