Jurupa Valley, CA Noise Ordinances: Decibel Limits (2026)

Jurupa Valley’s Chapter 11.05 (adopted by Ordinance No. 2012-01) takes the standard California pattern: a Table 1 of base exterior sound-level standards at the receiving property line, expressed in A-weighted decibels (dBA). The receiving property’s land-use category controls (residential parcels get the strictest standard; commercial higher; industrial highest). The standard is measured at a height typical of a property line, using an ANSI Type 1 or Type 2 sound-level meter, with a daytime tier (commonly 7:00 a.m. to 10:00 p.m.) and a nighttime tier. Section 11.05.060 "special sound source standards" addresses specific noise sources that the property-line standard alone may not adequately cover — typically including loudspeakers / amplified sound, construction, motor-vehicle repair, mechanical equipment, and animal noise. Compliance with the property-line dBA standard does not excuse a separate “special sound source” violation. Because Chapter 11.05 was adopted from the unincorporated-Riverside-County code at incorporation, residents transitioning from County jurisdiction (1990s–2011 vintage) will find the framework familiar. Section 11.05.040 also references a permit-event provision: "no activity for which a temporary event permit is issued shall create any sound, or allow the creation of any sound, on any property that causes the exterior sound level on any other occupied property to exceed the sound level standards set forth in Table 1 of Section 11.05.040, or that violates the special sound source standards set forth in Section 11.05.060." That confirms the basic two-track structure (Table 1 plus special-source rules) and confirms even permitted events must respect both. Sound measurements that exceed the Table 1 standard by a fixed offset (the County’s framework typically used “5 dBA above” as the threshold for a clear violation) constitute a code violation. Code Enforcement (951-332-0790) responds to complaints and may use a calibrated meter to document violations.
