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.
Isleton FAQ
Can a restaurant run its HVAC at night?
Yes, but equipment must be muffled or screened so noise at the nearest residence stays at or below 50 dB during nighttime quiet hours.
Are early-morning beverage deliveries allowed?
Deliveries should occur between 7 AM and 10 PM. Earlier deliveries require special accommodation and may be cited if they disturb neighbors.
