Chicago Metro Building Permits Guide
Chicago Department of Buildings permits required for structural, electrical, plumbing. Licensing in IL is managed by Illinois Plumbing License + local Cook County permits. Most Chicago Metro homeowners should require their contractor to pull permits in the contractor's name so liability for code violations rests with them.
Key points
- Confirm whether your scope triggers a IL permit (structural, electrical, plumbing, mechanical, additions, demo).
- Have your licensed contractor pull the permit in their name — this shifts inspection liability to them.
- Budget 1–3% of project value plus plan-check fees (USD 200–USD 1,500 depending on scope).
- Schedule rough-in and final inspections in advance — re-inspections cost extra and delay the build.
