Most renovation work in Chicago requires a building permit from the Department of Buildings. Permits are required for new construction, major repairs, alterations, additions, and renovations. Cosmetic work (painting, flooring) is exempt. Permit fees are calculated based on project valuation.
The Chicago Building Code requires permits for most renovation work. Permits are required for: structural alterations (removing or adding walls), electrical work, plumbing work, HVAC installation or modification, window or door replacements changing openings, roofing replacement, and any work visible from the street on landmark buildings. Work exempt from permits includes: interior painting and wallpaper, replacing floor coverings, replacing kitchen cabinets (no plumbing changes), and minor cosmetic repairs. Chicago uses an online permitting system (IPI Portal) for applications. The Easy Permit program provides expedited processing for qualifying smaller projects. The 10-day aldermanic notification period applies to most permits. Licensed contractors are required for work requiring permits. The Department of Buildings conducts inspections at various stages of permitted work. Historic landmark buildings require additional review by the Commission on Chicago Landmarks.
Performing work without required permits violates the Chicago Building Code with fines from $500 to $1,000 per day. Unpermitted work may need to be exposed for inspection. Stop-work orders can halt construction until permits are obtained.
