City of Naperville Building Department, Permits & Construction Profile

Naperville is a Civic Access profile with strong staff triage behind the portal. The city tells applicants to choose the primary project feature first, then staff can create related permits for secondary features such as a pool, patio, and fence. Simple work such as fences or driveways may review in less than one week, complex projects such as new single-family homes may take three to four weeks, inspections should be scheduled at least 72 hours in advance, and plans submitted on or after April 1, 2026 are reviewed under Ordinance 26-010. Historic districts and local landmarks add another layer because the Historic Preservation Commission uses local regulations, the Historic Building Design and Resource Manual, and the Your Place map to evaluate Certificate of Appropriateness questions.

Start with the Primary Feature, Then Let Staff Split the Rest

For projects with multiple features, Naperville tells applicants to identify the primary feature and apply for that permit; staff can then identify and enter related permits that belong to the same project.

Historic Properties Can Add a Coa Path

Naperville's historic district regulations point applicants to local preservation code, the Historic Building Design and Resource Manual, the 2008 survey, and the Your Place map for historic-district or landmark research.

April 2026 Code Adoption Changes Plan Review

The Building Permits page says Ordinance 26-010 applies to plans submitted on or after April 1, 2026, so older checklist habits may not match the code basis staff now uses.

Issued-permit Reports Expose Real Construction Activity

Naperville publishes monthly detail and summary reports for issued building permits, including permit type, contractor, valuation, and estimated-cost information, which is useful context for market and project research.
