The Average Cost of Adding a Garage
- According to Fixr Inc., a basic garage with only room for one car costs around $7,500 in 2011. This runs to $35 to $45 per square foot counting all work, which can be a much more useful number for homeowners than averaging the cost of a total garage. While some garage sizes are standard, homeowners may prefer to add extra space for storage or just wiggle room, so costs per square foot can be very useful. A two-car garage, on average, costs between $13,000 and $17,000 if it is built to the same standards as a one-car version.
- These average costs apply to only very basic garages with simple materials, like poured cement, vinyl siding and very little electrical work or insulation. According to Cost Helper, with higher-quality materials the costs can rise to $55 or $60 per square foot. A one-car garage with extra features can cost around $13,000, while the two-car garage can cost around $20,000. For a fully built garage with all insulation, heating and electricity desired, prices range more between $30,000 and $40,000.
- Homeowners who have experience in many aspects of construction can save money by building many parts of the garage themselves. If homeowners use a simple design for a single-car garage without windows, they may be able to build it for only $3,000 to $4,000 in 2011. A kit to create a garage using pre-fab construction materials cost between $5,000 and $14,000 for a do-it-yourself project.
- Carports are basic wooden frames that are cemented in a concrete slab and have a basic gable roof to provide a relatively secure place to park a car without resorting to the expense of a full garage. According to Repair-Home, in 2011 this cost only around $2,000 for a single-car version, although prices increase up to $6,000 for the double-car version.
