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

Murrieta treats noise as the central complaint pathway for short-term rentals. Under Chapter 9.02 of the Municipal Code, an STR property is subject to the same 55 dBA day / 45 dBA night residential limits and the plainly-audible-at-50-feet test as any other dwelling. The STR ordinance additionally holds the operator (not just the guest) strictly responsible for code violations that originate from the property. Operators must post a local contact phone number inside the unit and on the exterior, answerable 24/7 and able to respond within 60 minutes to address complaints. Two documented noise violations within a 12-month period typically trigger a compliance review, and three may result in suspension or revocation of the STR permit. Good Neighbor notices are required at the entry of the unit listing quiet hours, trash rules, and the local contact. Properties in Copper Canyon, Greer Ranch, and Alta Murrieta are the most common sites of guest-party complaints; HOAs in these communities often have separate rules that may prohibit STRs entirely or impose additional quiet-hour restrictions.
