Menifee FAQ
An industrial site next to my home runs noisy equipment at night — what code applies?
MMC §9.210.060 caps exterior noise at the receiving-property line to the General Plan Noise Element standards (typically 60 dBA nighttime residential). File a complaint with Menifee Code Enforcement at (951) 672-6777 — they will respond and may require sound measurements.
Do industrial uses get a higher noise allowance?
The receiver controls the limit, not the source. A factory next to homes must meet the residential receiver standard at the residential property line, regardless of the factory's own zoning.
Can the city require a sound wall as a condition of approval?
Yes. Under §9.210.060 and the CUP findings provisions of Title 9, the Planning Commission and City Council routinely impose sound walls, hour limits, equipment enclosures, and acoustic monitoring as conditions on new industrial entitlements.
