Carmichael FAQ
Does the commercial limit apply at my warehouse fence line?
Yes, but only where it abuts a residential parcel. Industrial-to-industrial boundaries use the higher 70 dBA threshold.
Can I operate overnight if zoned M-2?
Generally yes, but overnight operations adjacent to residential require a conditional use permit with noise-mitigation conditions.
Folsom FAQ
A loading dock behind my house runs at 5 AM — is that legal?
Not if sound at your property line exceeds 55 dBA during nighttime (10 PM-7 AM). Report to Folsom Code Enforcement with a log of incidents and timestamps.
How are dBA measurements taken?
City staff or a contracted acoustical consultant measure at the property line using an ANSI Type 2 sound level meter over a 15-minute period (Leq).
