Naperville Residential Building Permit Guide

Naperville requires homeowners to obtain building permits before many residential projects, including additions, remodeling, decks, patios, fences, pools, driveways, and accessory outbuildings.

Permit takeaway

Naperville says residents must obtain necessary building permits before beginning new construction projects, including new buildings, additions and remodeling, decks, patios, fences, and pools.

Zoning and placement

Outdoor work can involve zoning, easements, stormwater, major roadways, historic districts, right-of-way conditions, and utility access before the building permit is issued.

Building and trade review

Naperville adopted the 2024 ICC building codes for permit applications submitted on or after April 1, 2026, and uses the Civic Access portal for many residential applications.
