Mead Valley, CA Short-Term Rentals: Noise Rules (2026)

Riverside County Ordinance No. 927, Section 8(i)(1)-(2), imposes layered noise controls on short-term rentals in unincorporated areas. Operators, guests, and other occupants must comply with Riverside County Ordinance No. 847, which sets quiet hours between 10 PM and 7 AM, and with Riverside County Ordinance No. 924, which addresses loud or unruly parties, gatherings, or similar events. Outdoor amplified sound-any sound increased by amplified equipment or electronically enhanced-must comply with Ordinance No. 847. To enforce this, the operator must install and maintain in continuous operation a Noise Monitor on the exterior of the rental; the ordinance defines a Noise Monitor as a sound-level meter meeting American National Standards Specifications (or a similar device) that has no camera, does not record conversations, and stores no personal data. A working Noise Monitor is one of the three items the County verifies during exterior inspections. The operator must use reasonably prudent business practices to ensure guests comply, and must respond within 60 minutes of being notified of unreasonable noise or disorderly conduct to halt or prevent its recurrence (Section 8(w)). Outdoor fire areas must be extinguished by 10 PM or when no longer in use. The quiet-hours requirement must be disclosed in advertising and posted inside the unit (Sections 8(q) and 8(s)).
