Antioch Municipal Code regulates construction activity to protect residential neighborhoods from excessive noise. Permitted construction hours are 7:00 AM to 7:00 PM Monday through Friday, and 8:00 AM to 5:00 PM on Saturdays. Construction, including use of power tools, heavy equipment, pile drivers, jackhammers, and delivery of construction materials, is generally prohibited on Sundays and observed federal holidays. Emergency repairs — such as burst water pipes, storm damage, or hazardous conditions — are exempt but should be reported to the city. Contractors working on city-funded projects may have additional restrictions in their contracts. Violations can result in citations, stop-work orders, and fines.
