Full Breakdown
Section 9.210.060 of the Menifee Development Code sets citywide stationary source noise standards. No person may create sound that causes exterior levels on another occupied property to exceed 65 Leq (10-minute) between 7 a.m. and 10 p.m. or 45 Leq (10-minute) between 10 p.m. and 7 a.m. Interior standards are 55 Leq day and 40 Leq night. Measurements are taken anywhere within the boundaries of the occupied receiving property using a calibrated sound level meter. Like Riverside County, Menifee exempts heating and air conditioning equipment in proper repair, which covers much of a data center's cooling load. Backup generators and other plant equipment remain subject to the table.
Violations & Fines
Sound above the Table 9.210.060-1 limits is a Development Code violation enforced by peace officers and code enforcement officers; refusing to cooperate with an officer measuring the sound is a separate violation.
