What is the average cost per square foot to brick a home?

That depends on where you are building, who is doing the building, the amount of add-ons (the fanciness of things such as cabinets, Plumbing fixtures, flooring etc.) If you already own your land, then it can be done for as low as $80-$85 per square foot. If you do not own your own land, then you will be lucky to get it under $100 per sq ft.
