Perris, CA Noise Ordinances: Industrial Noise (2026)

Industrial and warehouse/distribution operations in Perris are subject to two layers of city regulation. First, the general noise limits of Chapter 7.34 apply citywide, capping noise at the property line per section 7.34.040. Second, the zoning code's Industrial Zones chapter sets performance standards in section 19.44.070: subsection (b) requires that noise generated on-site be controlled to be compatible with surrounding land uses, and that any proposed use which may generate noise during evening hours (defined as 7:00 p.m. to 7:00 a.m.) must submit a detailed noise assessment and plan addressing and mitigating potential noise impacts. The same section requires that on-site vibrations not be detectable off-site (with a vibration assessment required if they might be), and addresses electrical disturbance, odors, dust and airborne pollutants. These standards are applied through the development-review process for new and expanded industrial uses, including the very large warehouse/distribution centers (500,000 square feet and larger) that the chapter separately calls out for design standards. Because Perris is incorporated, section 19.44.070 and Chapter 7.34 govern industrial noise inside the city; Riverside County standards apply only to unincorporated industrial areas.
