Every home remodel and renovation is different. Cost per square foot can vary depending on the age of the home, the size of the space being remodeled (e.g. an older house might have a smaller kitchen), and items like plumbing and electrical which can also raise the cost of a home remodel. On average, the cost per sq. ft can range between $100 to $1000. Luxury remodels can be double that price. The best way to get a cost estimate on any type of home remodel is to call a licensed remodeling contractor.
