Naperville establishes maximum building heights by zoning district under Title 6. Height limits vary from residential to commercial and industrial zones. Accessory structures have separate height restrictions. Variances require Zoning Board of Appeals approval.
Naperville Municipal Code Title 6 (Zoning Regulations) establishes maximum building heights for each zoning district. Residential districts typically limit building height based on stories and feet. Commercial and industrial districts may allow taller structures. Accessory structures under Section 6-2-10 have separate, generally lower, height limits. Building height is measured from grade to the highest point of the roof. Chimneys, antennas, and mechanical equipment may extend above the height limit with restrictions. The city's historic district may have additional height considerations per planning guidelines. Height variances require approval from the Zoning Board of Appeals with demonstration of hardship. All new construction must demonstrate height compliance through the building permit process.
Exceeding height limits: building permit denied or stop-work order. Existing structures exceeding limits: legal non-conforming status may apply. Height variance requires ZBA approval.
