Full Breakdown
Naperville Municipal Code § 3-9-1(2) exempts restaurants and taverns that hold a valid City liquor license and sit in a B4-zoned district from the general amplifier permit required elsewhere in the chapter. They may play recorded music, business announcements, and live entertainment, but recorded sound must stop by 12:30 a.m. Monday through Friday and 1:30 a.m. Saturday and Sunday (never before 9:00 a.m.), live music must stop by midnight on weekdays and 1:00 a.m. on weekends, and none of it may be audible more than 300 feet beyond the property line. Exceeding these limits requires City Council approval under § 3-9-4.
