Architectural Design in Chicago, IL
Chicago is one of the most architecturally significant cities in the world — and one of the most demanding commercial permitting environments in the US. The Chicago Building Code is a separate code from the statewide Illinois Building Code, with its own chapter structure, unique requirements, and an active Chicago Department of Buildings (CDB) review process. Jason Mitchell's Illinois architectural licensure enables Torch to navigate this environment as architect-of-record for Chicago commercial, mixed-use, and institutional projects.

Local market drivers
- Chicago Building Department (CDB) administers commercial permits — the Chicago Building Code is distinct from statewide Illinois code
- City of Chicago does not use the International Building Code directly — the Chicago Building Code has its own structure and requirements
- Chicago's dense urban core drives tenant improvement, adaptive reuse, and mixed-use development architectural demand
- Landmark designation review through Chicago Landmarks Commission applies to contributing buildings
Permitting & jurisdiction
Chicago Department of Buildings (CDB) handles commercial building permits. Chicago uses its own Chicago Building Code (CBC) — not the IBC — with significant differences in occupancy classifications, egress requirements, fire protection, and structural standards. Chicago Fire Department review is required for all commercial occupancies. Chicago Landmarks Commission review applies to designated landmarks and properties in Chicago Landmark Districts.
FAQs
Does Torch hold Illinois architectural licensure for Chicago projects?
Yes. Jason Mitchell holds Illinois architectural licensure from the Illinois Department of Financial and Professional Regulation (IDFPR), which is required for commercial architectural practice in Illinois. Torch navigates the Chicago Department of Buildings permit process and prepares construction documents that comply with the Chicago Building Code — which differs materially from the IBC used in most other US jurisdictions.
What makes the Chicago Building Code different from the IBC?
The Chicago Building Code (CBC) has been developed independently of the International Building Code (IBC) and differs from IBC in significant ways: occupancy classifications, egress corridor dimensions, fire protection requirements, and structural provisions all have Chicago-specific language. For engineers and architects familiar only with IBC jurisdictions, the Chicago code requires careful review. Torch designs to CBC requirements as standard practice for Chicago projects, including coordination with the Chicago Fire Prevention Bureau for assembly and institutional occupancies.
