Home Addition Cost

There are many options to choose from when planning to add extra space to your home. You can add a bathroom, master bedroom suite, build an in-law apartment, build a detached garage, family room, or add a second floor.

Building an addition increases the square footage, which adds value to a home. Each type of addition project has estimated prices primarily based on the size that we’ll cover below.

Home Addition Cost Per Square Foot

A home addition costs between  $86 and $208 per square foot , with most spending  $128 per square foot  on average. The final cost depends on if your building-up or building-out, labor costs, and the quality of materials used.

On average, the addition consists of a basic room with necessary electrical wiring and little to no plumbing. Features such as bedrooms and bathrooms with luxury fixtures start raising that square footage price. Every door, window, and wall adds to the price. The more luxurious the design of the addition, like a chef’s gourmet kitchen with smart appliances and heavier electrical needs, the higher the price—at  $400 per square foot  or higher.
