What Drives Detached Garage Costs in Chicago
Permits & zoning
Chicago detached garages require a building permit through the Department of Buildings, typically $200–$450 plus zoning review. Detached garages must observe a 2-foot side setback and 3-foot rear setback. Total accessory structure footprint cannot exceed 700 sq ft on most residential lots.
Climate & construction
Cook County frost depth is 42 inches, so foundations require extended frost footings. Walls and overhead doors typically need R-13+ insulation for heated use. Roof framing must rate for 30 psf snow load minimum.
Local market
On standard 25-foot Chicago lots, a 20×20 two-car detached garage with alley access is the most common build. Local costs run roughly 10–18% above the Midwest baseline due to union labor rates and high demolition fees. Add $4,000–$8,000 if an existing garage must be removed first.
