Summary
Port Hueneme sets exterior noise limits by the receiving property, not the source. Municipal Code Section 3430 caps industrial property at 75 dB(A) anytime, commercial at 65 dB(A), and residential at 55 dB(A) from 7 a.m. to 10 p.m. and 50 dB(A) overnight.
The following Exterior Noise Levels, unless otherwise specifically indicated, shall apply to all receiving properties within a Designated Noise Zone for the purpose of establishing Noise Level Limits in Section 3431 below.
Full Breakdown
Article III, Chapter 5 of the Municipal Code is the city's Noise Control ordinance. Section 3429 assigns every receiving property to a Designated Noise Zone, and Section 3430 sets the Exterior Noise Level for each: residential at 55 dB(A) from 7 a.m. to 10 p.m. and 50 dB(A) overnight, commercial at 65 dB(A) anytime, industrial at 75 dB(A) anytime. Section 3431 makes those levels enforceable when exceeded for more than thirty minutes in any sixty, with stepped allowances for shorter durations. Section 3433 applies the lower limit at a zone boundary. Section 3434 subtracts 5 dB when the noise contains a hum or whine, which is what data-center chillers and generators produce. Section 3438 names fans and air conditioning directly.
Violations & Fines
Noise over the Section 3431 limits is an infraction fined under Section 1102, enforced by the Director of Community Development through notices of violation, abatement orders, and public nuisance abatement.
