Home addition cost estimates of $80 to $130 per square foot for a basic family room addition is common. $124
The actual per square foot cost formula simply involves dividing the total cost of the home construction project by the total square feet of the project. For example, if a 400 square foot home addition costs $50,000 to build, the per square foot cost for the home addition would be $125. There are many factors that must be considered in order to calculate cost per square foot on a home construction project. In addition, the per square foot cost is sometimes shown in two different ways, one with the cost of the building lot included and one without. Room addition cost estimates can vary dramatically due to a number of factors, chief amongst them being what is specified in the room addition plans. For example, room addition costs estimates of $80 to $130 per square foot for a basic family room addition is common. If the room addition includes bathrooms and/or a kitchen, the room addition costs can easily escalate to $200-250 per square foot. By: Mark J. Donovan. Building a room addition is an expensive proposition. Home remodeling contractors typically specify room addition costs in dollars per square foot to provide a rough order of magnitude cost estimate. 1 Hiring a remodeling contractor to build a second floor addition can run $100-$300 a square foot for the typical addition (2-3 bedrooms and a bath plus a flight of stairs), but can go as high as $400-$500 per square foot depending on complexity, quality of materials and local labor rates.  Costs Vary Widely. Nationally, estimates of room addition costs vary from $80 to $250 a square foot. A simple room addition with a basic foundation and no plumbing generally costs at least $100 a square foot with typical internal finishing, no expansion of a heating/cooling unit, and minimal structural changes. The cost per square foot decreases as the size of the addition increases. An addition that includes a kitchen will require plumbing and boost costs. An addition with a kitchen can run $250 to $300 a square foot, not counting finishing details like appliances and countertops. An addition with a bathroom can cost $125 to $200 a square foot, again with a number of cost variables including type of flooring, shower and tub, plumbing appliances or custom lighting If on the other hand the same square foot home addition costs $75,000 to construct, because for example the inclusion of high end materials or a bathroom, the cost per square foot would be $187.50. In addition, the amount of square feet to use in the per square foot cost calculation can also be a variable. There are many factors that must be considered in order to calculate cost per square foot on a home construction project. In addition, the per square foot cost is sometimes shown in two different ways, one with the cost of the building lot included and one without. 1 The above figures place the cost of the addition at $124 per square foot. 2  This pricing structure assumes that carpenters charge an average of $70 per hour, electricians between $65 to $85 per hour, and painters between $20 and $35 per hour. Adding on to any home, whether it is an expansion of the existing footprint or an entirely new level is a very complex project. For this discussion we will examine the requirements and general costs associated with adding a single-story 192 square foot (12'x16') room. Primary factor, specifications of in the room addition plans. Examples: 1  Home addition cost estimates of $80 to $130 per square foot for a basic family room addition is common. 2  If the home addition includes a bathroom and/or a kitchen, the room addition costs can easily escalate to $200-250 per square foot. 1 The above figures place the cost of the addition at $124 per square foot. 2  This pricing structure assumes that carpenters charge an average of $70 per hour, electricians between $65 to $85 per hour, and painters between $20 and $35 per hour. 1 Home addition cost estimates of $80 to $130 per square foot for a basic family room addition is common. 2  If the home addition includes a bathroom and/or a kitchen, the room addition costs can easily escalate to $200-250 per square foot. 3  Quality and materials used are the other cost factors in a home addition. 1 The above figures place the cost of the addition at $124 per square foot. 2  This pricing structure assumes that carpenters charge an average of $70 per hour, electricians between $65 to $85 per hour, and painters between $20 and $35 per hour.
