How Much Does It Cost to Build a Garage?

Cost by garage size

Typical all-in costs:

  • One-car (around 240 sq ft): $20,000 to $30,000
  • Two-car (around 400 to 600 sq ft): $30,000 to $50,000
  • Three-car or with living space above: $50,000 to $100,000+

Attached vs detached

Attached garages share a wall and existing utilities, which can lower cost, but they need to tie into the home structure. Detached garages are simpler to build but need their own foundation and separate utility runs if you want power or heat.

Frequently asked questions

Does adding a garage add home value?

Yes. A garage adds storage and parking that buyers want and usually recoups a solid share of its cost, especially in climates with snow or in neighborhoods where garages are expected.
