Summary

The City of Fresno's own Noise Ordinance (Municipal Code Chapter 10, Article 1) sets sound levels by district: 60 dBA daytime, 55 evening, and 50 dBA overnight in residential areas, and 70 dBA anytime in industrial areas. Data-center cooling and generators must comply.

Any noise or sound exceeding the ambient noise level at the property line of any person offended thereby, or, if a condominium or apartment house, within any adjoining living unit, by more than five decibels shall be deemed to be prima facie evidence of a violation of Section 8-305.

Full Breakdown

Fresno's Noise Ordinance, Municipal Code Chapter 10, Article 1, designates ambient sound levels by district and time of day. Residential: 60 dBA (7 a.m.-7 p.m.), 55 dBA (7 p.m.-10 p.m.), and 50 dBA (10 p.m.-7 a.m.). Commercial: 65 dBA daytime, 60 dBA overnight. Industrial: 70 dBA at any hour. Under Section 10-106, any noise exceeding the ambient level at the property line by more than five decibels is prima facie evidence of a violation. A data center's fans, compressors, and generators - named in Section 10-105 - are measured at the property line, so the 50 dBA residential overnight floor binds where an industrial site abuts homes.

Violations & Fines

Noise exceeding the designated level at a neighbor's property line by more than five decibels is a Municipal Code violation, enforced by the City through citations, fines, and injunctive relief.
