Building a 2-car detached garage in the U.S. typically costs between $30,000 and $60,000, with a national average around $45,000. The final price is highly variable and depends on factors like size, materials, foundation, and whether you include electrical wiring or plumbing. A basic, unfinished structure ("shell") starts lower, while a fully finished garage with high-end materials and amenities can exceed $75,000.
The primary cost drivers are materials and labor. A stick-built wood frame garage is the most common, but metal buildings can be a more affordable option. The foundation is another significant expense; a simple gravel base is cheapest, while a poured concrete slab is the standard and adds to the cost. Labor typically accounts for about one-third of the total project budget.
| Cost Factor | Low-End / Basic | Mid-Range / Standard | High-End / Custom |
|---|---|---|---|
| Total Project Cost | $20,000 - $30,000 | $35,000 - $55,000 | $60,000+ |
| Cost per Square Foot | $50 - $70 | $75 - $125 | $150+ |
| Foundation (Concrete Slab) | $5,000 - $7,000 | $7,000 - $10,000 | $12,000+ |
| Framing & Roofing | $8,000 - $12,000 | $13,000 - $20,000 | $25,000+ |
| Siding & Doors | $4,000 - $6,000 | $7,000 - $12,000 | $15,000+ |
| Electrical Wiring | $1,000 - $2,000 | $2,500 - $4,000 | $5,000+ |
| Permits & Fees | $500 - $1,500 | $1,000 - $2,000 | $2,500+ |
Don't forget to budget for permits, which are legally required in most areas and ensure your structure is up to code. Getting multiple detailed quotes from licensed local contractors is the best way to understand the specific costs for your property.

You're looking at a ballpark of $40,000 to $50,000 for a standard build. My advice is to talk to at least three contractors. The quotes can vary wildly. Ask them to break down the costs for materials, labor, and permits. The biggest surprise for many folks is the permit cost, which can add a couple thousand dollars. Go with a contractor who is clear about this from the start.

We just built one last year. Our 24x24 foot garage with a simple concrete floor and basic siding came in right at $42,000. That included running electricity for lights and outlets. The price was higher than we first hoped, but that was the going rate in our area. My tip is to be very specific about the door you want; that was a bigger line item than we expected.

If you're handy, you can save a lot by acting as your own general contractor and sourcing materials. However, the foundation and electrical work are best left to pros. A basic DIY shell using a kit might cost $15,000-$25,000 in materials, but that's before the concrete work. It's a lot of work, but the potential savings are significant if you have the time and skills.

Think beyond just parking cars. A well-built garage adds tangible value to your property. While you might spend $50,000, it can increase your home's resale value significantly, often recouping a good portion of the investment. It's also about utility—extra storage, a workshop, or a protected space for your vehicles. View it as a long-term upgrade to your property's functionality and worth.
