BBQ & Propane Rules
Naperville has not adopted a separate municipal BBQ ordinance; outdoor cooking is governed primarily by the Illinois Fire Code (Office of the State Fire Marshal adoption of NFPA 1 under 41 Ill. Adm. Code 100) and the IFC provisions referenced through Naperville's Title 5 Chapter 1 (Building Codes) and fire-prevention provisions enforced by the Naperville Fire Department Community Risk Reduction Division. The controlling rule for multifamily and combustible balconies is IFC/NFPA Section 308.1.4: charcoal burners and open-flame cooking devices may not be operated on combustible balconies or within 10 feet of combustible construction, with exceptions for one- and two-family dwellings, sprinklered buildings, and LP-gas containers of 2.5-pound water capacity or less.

Some RestrictionsSmoker Rules
Outdoor smokers (charcoal-fueled, wood-pellet, or propane-assisted) are treated as open-flame cooking devices under NFPA 1 Section 10.11 and IFC Section 308.1.4, the same standard applied to BBQ grills. Naperville has no smoker-specific ordinance. Single-family and two-family yards may use smokers with normal precautions; combustible balconies of non-sprinklered multifamily buildings are off-limits within 10 feet of construction. Naperville's general 50-foot setback for cooking fires from structures (15 feet if in an approved container) and smoke nuisance prohibitions apply.
