Summary
Moreno Valley's noise ordinance caps nonimpulsive sound at the property line and, unlike Riverside County, expressly regulates air conditioning and continuously operating equipment. Municipal Code Section 11.80.030 limits residential-source sound to 60 dB(A) daytime and 55 dB(A) nighttime, measured 200 feet from the property line.
Notwithstanding the general prohibitions of subsection a of this section, no person shall operate or permit the operation of any pump, air conditioning, air-handling or other continuously operating motorized equipment in a state of disrepair or in a manner which otherwise creates a noise disturbance distinguishable from normal operating sounds.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: rev 4887234; v10 updated 2026-04-07).
Full Breakdown
Moreno Valley's Noise Regulation ordinance, Municipal Code Chapter 11.80 (Ordinance 740), makes it unlawful to create nonimpulsive sound exceeding Table 11.80.030-2 when measured 200 feet or more from the source's real property line. The caps by source land use are: residential 60 dB(A) daytime (7 a.m.-10 p.m.), 55 dB(A) nighttime (10 p.m.-7 a.m.); commercial 65 dB(A) daytime, 60 dB(A) nighttime. The table sets no industrial figure, so an industrial data center answers to the noise-disturbance standard. Critically, Section 11.80.030(D)(10) bars any air conditioning, air-handling, pump, or continuously operating equipment that creates a noise disturbance - the county exempts such HVAC equipment.
Violations & Fines
Nonimpulsive noise over the Section 11.80.030 limits, or HVAC and continuously operating equipment causing a noise disturbance, is a misdemeanor the city may cite as an infraction or public nuisance.
