A professional garage conversion costs $50 to $200 per square foot or $5,000 to $50,000+, depending on the size and features of the new living space. A garage-to-apartment conversion costs $20,000 to $100,000+. This is typically a much more complex project involving framing, drywall, building a bathroom and kitchen, adding heating and cooling, and finishing the interior. You may also need new doors and windows to comply with local building and zoning codes.
If you want to give your garage a face lift but keep it functioning as a garage:
- A partial garage renovation focused on simple cosmetic updates like new paint, resurfaced flooring, or a new door costs $1 to $10 per square foot or about $500 to $5,000 total.
- Remodeling or finishing a garage costs $10 to $30 per square foot or $3,000 to $17,000 total on average for new flooring, integrated storage cabinets and shelves, finished walls, and a new garage door.
