Cost to Build a 3-Car Detached Garage

Two vehicles can consume a surprising amount of garage space once you add bikes, tools, storage, or a workbench. Building from scratch gives you room to account for all of it, but the cost to build a three-car detached garage varies considerably based on the footprint and the choices made around it. For early budgeting, expect roughly $30,000 to $80,000 for many straightforward wood-framed three-car garages, with finished interiors, difficult sites, and premium exterior materials capable of pushing the total beyond $100,000.
