Perris, CA Noise Ordinances: Quiet Hours (2026)

Chapter 7.34 of the Perris Municipal Code sets the city's noise rules, and two of its sections run on the same decibel table. Section 7.34.040, titled Sound amplification, begins: "No person shall amplify sound using sound amplifying equipment contrary to any of the following." The first condition is that the only amplified sound permitted is music, the human voice, or both. The second caps the volume of amplified sound, measured outdoors at or beyond the property line of the property from which the sound emanates, at 60 dBA from 10:01 p.m. to 7:00 a.m. and 80 dBA from 7:01 a.m. to 10:00 p.m. Sound amplifying equipment means any machine or device for the amplification of the human voice, music or any other sound, and standard vehicle radios used and heard only by the occupants of the vehicle are excluded.

Section 7.34.050, the general prohibition, uses that table too. Subsection (a) makes it unlawful to willfully make, cause, suffer or permit loud, excessive or offensive noises or sounds that unreasonably disturb the peace and quiet of any residential neighborhood, that are physically annoying to persons of ordinary sensitivity, or that are so harsh, prolonged or unnatural or unusual in their use, time or place as to occasion physical discomfort to the inhabitants of the city or any section of it. It then states: "The standards for dBA noise level in section 7.34.040 shall apply to this section." It adds a presumption: to the extent the noise causes the level at the property line to exceed the ambient noise level by more than 1.0 decibels, the noise is presumed to violate the section as well. Section 7.34.020 defines the ambient noise level as the level obtained when noise is averaged over a period of five minutes without inclusion of noise from isolated identifiable sources.

Subsection (b) lists nine conditions to weigh: the level of the noise, whether it is usual or unusual, whether its origin is natural or unnatural, the ambient level, its proximity to sleeping facilities, the nature and zoning of the area where it emanates and where it is received, the time of day or night, its duration, and whether it is recurrent, intermittent or constant. Both sections carry the history note citing Ord. No. 1082, § 2(part), 2000.
