The cost to build a 20x20 garage varies widely based on materials, location, and finishes, but a typical range is between $20,000 and $40,000 for a basic, detached structure. A simple, unfinished garage with a concrete slab, standard framing, and asphalt shingle roofing often falls on the lower end. Costs escalate significantly with added features like insulation, drywall, electrical wiring, plumbing, or higher-end siding and doors. Permits, site preparation, and labor are major cost factors. For a fully finished garage that can serve as a workshop or living space, prices can easily exceed $50,000. It is crucial to obtain detailed quotes from licensed contractors who account for local building codes and site-specific conditions.
