When it comes to building any home, there are so many variables that play into pricing. Technically speaking the price per square foot of a home is simply the total cost of the home divided by the total square feet. When trying to compare prices of homes, be sure to compare apples to apples. In the home building industry, there is no official standard for what constitutes a square foot. One price might include the framing, drywall, electrical and plumbing, but none of the interior finishes like flooring, cabinetry, and finish bathrooms. A price from another builder might include all of that, plus high quality flooring, fixtures, cabinets, and foundation.modularhome.org
If you are trying to compare the cost of a modular home and the cost of a stick built home, be sure each builder has identified every cost associated with your build, including building blueprints and plans, building materials, inspections, labor costs, bids from subcontractors, foundation, and utilities just to name a few.
Also, be sure to understand what square footage number someone is using. Is it a livable square feet, or simply the square footage calculated using the exterior dimensions of the house? Livable square feet does not include porches, garages, and unfinished space like attics.
Not every square foot of a home is like every other. One square foot in a bedroom might include the joist, sub floor, carpet, drywall ceiling, and attic space. One square foot in the kitchen might include everything in the previous example plus upgraded countertops, tile backsplash, and elaborate hardwood custom cabinets.
Likewise, a price per square foot of a 1,500 square foot house built to the minimum code standards will be much lower than the price per square foot from a builder who includes higher quality building material and upgraded finishes standard in the price. You must also figure out if the foundation is included in that square footage price, and what type of foundation it is.
Asking the cost per square foot of a home is like asking a car salesperson what the cubic foot price is of their cars – it depends on the type you’re purchasing and the features it has!
