New Garage Costs. 1  According to HomeAdvisor.com, a new garage costs between $9,000 and $45,000, with an average cost of roughly $20,000 to $30,000. 2  Per square foot (psf), expect garage prices to begin at $30 to $50 psf for basic materials.
Most contractors would recommend building as big as you can for convenience of storage, extra room and to alleviate the risks of opening car doors (size needed: typically 24' X 24' or larger). Figuring out what size of a garage you want is the first step in determining the cost per square foot. A good rule of thumb to remember is that a starting point for the most basic garage is about $30 per square foot. Therefore, you're starting off at about $12,000 for a standard 20' X 20' garage â but you'll soon find out that number will have a tendency to rise quickly.
