Chicago: Union Labor, Aldermanic Approval, Winter Weather
Building permits take 4-6 weeks (longer for landmark buildings). Quality contractors book 3-4 months out. Costs: $61-106/sqft. Chicago is one of the most union-dense markets in the US (75-80% union)-expect 20-30% cost premium vs open-shop but excellent craftmanship and adherence to schedules.
Chicago specifics:
- Aldermanic Approval: Projects over 7,500 sqft need ward alderman sign-off. Can add 2-4 weeks. Politics matter-experienced contractors know the process.
- Loop/River North: Competitive contractor market. Parking/loading restrictions tight. Weekend/night work often required (union premiums apply).
- Winter Impacts: Nov-Mar affects schedules. Material delivery delays common. Exterior work limited. Budget extra time for winter projects.
- Landmark Buildings: Commission on Chicago Landmarks reviews required. Can add 8-12 weeks. Strict preservation standards.
Union labor means higher costs but superior quality and less schedule risk. Experienced project managers essential for navigating CDOB and aldermanic processes. Cold weather contingencies mandatory for Q1/Q4 projects.
Why Chicago is Unique
Chicago Department of Buildings (CDOB) reviews permits in 4-6 weeks. Large projects (7,500+ sqft) require aldermanic approval (adds 2-4 weeks). Chicago is heavily unionized (75-80%)-higher costs but better quality control. Top firms book 3-4 months ahead, especially for Loop and River North projects. Winter weather (Nov-Mar) impacts delivery and exterior work.
