Garage Cost Planning Notes
Garage bids vary because contractors are pricing more than the shell. A realistic estimate should include the slab, excavation, drainage, driveway changes, framing, roofing, siding, electrical, doors, openers, insulation, and any required fire separation where the garage connects to the house.
Use the low range for a simple detached shell on a buildable lot. Use the high range when the project needs finished interiors, upgraded doors, apartment prep, difficult site access, utility trenching, or exterior matching.
