Cost of Building a Garage Addition

The cost of a garage addition can vary greatly depending on the size of the addition, the materials used, and any additional features. Generally, a basic garage addition can cost anywhere from $35,000 to $60,000. If additional features such as insulation, drywall, or windows and doors are added, the cost will increase. Additionally, the cost can be higher if the addition requires additional permits or if the garage is being built from scratch.
The cost of a garage addition can also vary depending on the type of materials used. For example, brick or stone may be more expensive than wood or vinyl. Additionally, the cost of labour will also affect the total cost. Working with a professional contractor from Magnolia can help ensure that the job is done correctly and that all necessary permits are obtained.
