West Loop
Chicago, Illinois

West Loop restaurant buildouts require a Chicago Department of Buildings building permit, a Chicago Department of Public Health food service facility plan review approval, a Chicago Fire Department permit for suppression systems, and a grease interceptor permit. If the project involves a change of occupancy in a historic warehouse building, an additional DOB review and sometimes a MWRD coordination step is required for projects near the Chicago River or tributary infrastructure. 32 Build manages every permit simultaneously to minimize the gap between approval milestones and construction start.

Commercial tenant improvements in the West Loop run $100 to $250 per square foot for standard office and creative studio buildouts, and $200 to $400 per square foot for tech-focused office buildouts with raised floors, high-capacity electrical, and server cooling infrastructure. A 5,000 SF tech office buildout in a Fulton Market building currently averages $500,000 to $2,000,000 depending on finish level and infrastructure requirements. Google, McDonald's, and other West Loop anchors have established a high baseline for office quality in the neighborhood.

A loft conversion in the West Loop — converting former commercial or industrial warehouse space into residential or live-work units — typically runs $175 to $375 per square foot depending on existing conditions, the extent of new MEP systems, window openings, and finish level. A 1,800 SF raw loft conversion in a West Loop warehouse building averages $315,000 to $675,000. Buildings with significant mechanical, asbestos, or structural conditions will trend toward the higher end. The neighborhood's warehouse loft buildings have been among Chicago's most sought-after residential addresses since the early 2000s.

A restaurant buildout in the West Loop typically takes 4 to 8 months from permit approval to certificate of occupancy and health department licensing, depending on scope and the condition of the shell space. Permit processing — DOB building permit, CDPH food service plan review, and CFD suppression permit — typically adds 8 to 14 weeks of pre-construction lead time. 32 Build begins the permit process at the earliest possible stage and manages all agency submissions simultaneously to compress lead times.

Fulton Market's historic warehouse buildings were built for cold storage and meatpacking, which means their structural systems — heavy timber post-and-beam or reinforced concrete flat-plate construction — are generally robust but require professional assessment before any structural modifications are made. Many buildings contain asbestos-containing materials in flooring, insulation, and pipe wrap from the early 20th century. Renovation scopes almost always include asbestos survey and abatement as a pre-construction step. The neighborhood's current popularity also means active construction on adjacent properties is common — 32 Build coordinates proactively with neighboring projects and building management to manage noise, access, and scheduling conflicts.

Yes. Tech office buildouts are a growing part of our West Loop commercial work — high-capacity electrical distribution, raised floor systems, server room cooling, advanced AV and video conferencing infrastructure, and high-quality open-plan finishes that reflect the standards set by the neighborhood's anchor tenants. We work with technology-focused MEP engineers who understand the power and cooling demands of tech-forward office environments. A complete tech office buildout in the West Loop typically runs $175 to $350 per square foot depending on infrastructure complexity and finish level.

Look for a contractor with an active City of Chicago General Contractor license, specific experience with restaurant or commercial construction in the West Loop and Fulton Market, and references from completed projects in the area. For restaurant work, ask about their CDPH food service plan review experience and CFD suppression permit process. For commercial buildouts, ask about their experience with the structural and MEP conditions typical of historic warehouse buildings. 32 Build has been working in the West Loop since the neighborhood's early development cycle and is happy to provide references, license credentials, and project photos.
