Selma, CA Noise Ordinances: Decibel Limits (2026)

Selma's noise ordinance includes specific technical standards for decibel measurement and enforcement. Section 6-17-2 provides definitions used in the noise chapter. Section 6-17-3 establishes decibel measurement criteria, defining how sound levels are to be measured for enforcement purposes. Section 6-17-4 sets monitoring procedures that officers must follow when investigating noise complaints. The key enforcement standard is Section 6-17-6 (Prima Facie Violation), which states that any noise or sound exceeding the ambient noise level at the property line of any person offended thereby, or within any adjoining living unit of a condominium or apartment house, by more than 5 decibels shall be deemed prima facie evidence of a violation of Section 6-17-5. Sound measurements are taken at the affected property line, not at the source. The ambient noise level serves as the baseline, meaning enforcement accounts for the existing noise environment in the area. This is a relative standard rather than a fixed decibel cap.
