Step-by-Step Guide to Converting a Carport to a Garage
Follow these detailed steps to successfully transform your carport into a functional garage
Check Local Codes and Plan
Permits may be required for a carport-to-garage conversion. Respect property lines and setback distances when expanding a carport. If close to a neighbor’s property, consult a land surveyor.
Plan carefully, ensuring the carport is sturdy and its height can accommodate a garage door. Work with a professional for accurate measurements.
Prepare the Carport
You will not need to dig a foundation for a carport conversion, but ensure the ground is stable with good drainage.
Remove any coverings from the joists and columns in the existing carport.
Build the Structure
Enclose the carport with walls using a pressure-treated bottom plate and wood studs spaced 16 inches apart. Cover the bottom plate with plastic to prevent moisture and attach the walls securely to the carport structure.
Add an access door and optional windows, ensuring the entrance door meets fire-safe requirements if attached to your house.
Install the Garage Door, Electricity, and Insulation
Ensure a slope at the door’s threshold for water drainage. Installing the garage door can be tricky; consider hiring a professional. Run electrical service and install garage insulation to regulate the temperature.
Complete the Transformation
Install drywall inside and siding outside. Add final design elements like paint or decorative moldings to personalize your garage. This completes your carport-to-garage conversion.

Proper Drainage

Key Considerations Before Starting a Conversion Project
Converting a carport to a garage can be a valuable investment for extra storage or a protected workspace. Before you start, here are a few important factors to consider.
Additional Costs
Once your carport is fully enclosed as a garage, you may need more than just new garage doors, depending on your intended use. Besides material and labor costs, consider installing utilities, insulation, and security features if you plan to use the space as a workspace or additional living area.
Structural Integrity
Ensure the existing carport structure, including the foundation and support beams, is in good condition and sturdy enough for the conversion. If significant repairs are needed, it might be more cost-effective to purchase a new garage instead.
