Summary
Temecula's noise ordinance, Municipal Code Chapter 9.20, caps exterior sound at the receiving property: 65 dBA at homes (70 for multifamily), 70 commercial, and 75 dBA at light-industrial land. But Section 9.20.030 exempts heating and air-conditioning equipment - so data-center cooling escapes the noise limits, matching Riverside County.
No person 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 Tables N-1 and N-2.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: rev 4862229; v11 updated 2026-04-14).
Full Breakdown
Temecula's own noise ordinance, Municipal Code Chapter 9.20, sets exterior sound-level standards by the receiving property in Table N-1 (Section 9.20.040): residential 65 dBA (up to 70 for multifamily), commercial and office 70 dBA, and light-industrial/industrial-park land 75 dBA, measured as the average of three readings over thirty minutes. Critically, Section 9.20.030(I) exempts "heating and air conditioning equipment" from the entire chapter - so a data center's chillers and cooling towers are not regulated by the ordinance, the same exemption Riverside County grants and the opposite of neighboring Murrieta. Backup generators, which are not HVAC, remain subject to the property-line limits.
Violations & Fines
Noise exceeding the Chapter 9.20 exterior standards is a misdemeanor enforced by Temecula code enforcement and police through citations; a permitted data center also breaches any noise conditions on its development plan or conditional use permit.
