How Much Does It Cost To Build An Attached Garage?
Build Attached Garage Costs
Attached garage construction, often also referred to as a garage addition, requires extensive work and has a lot of variables involved in the cost. For the sake of estimating purposes, we will assume adding a garage that measures 26 feet x 26 feet. This space totals 676 square feet, with more than enough room for two cars and plenty of storage. Because of the large scale of these jobs, they are not considered DIY projects and should be done by licensed contractors.
If you are replacing an existing garage, you will have to factor in demolition and site preparation. This could be at an additional charge if it is performed by a professional, or you may be able to do some of the work yourself to save money on labor costs. You will also have to consider the necessary steps in the garage construction process, including: concrete slab and footings, roof trusses and a support system, siding and trim, roofing, windows and man doors, overhead doors, and electrical wiring, lighting, and electric opener installation.
