Being detached from the home means that you have to endure the elements, whether it be snowing, hailing, raining, or sunny with yourself and any items you need to carry from the car to the home. This can make grocery shopping or moving things a real pain.

Detached garages are a great deal less cost effective in most circumstances as you are basically building an additional building. You need a new roof, walls, electrical, and anything else you want to incorporate into the garage. All of those have to be wired and built in the additional location which can be costly and time consuming.

You need a spot to build, and a spot for the driveway and a way to get from the garage to the home in a relatively unobstructed way. This can eat up a vast amount of yard space and is often not even an option for urban areas, or may not be allowed by certain local codes and homeowner’s requirements.

  • Less accessible (stored items/freezers are further away)
  • You have to walk through rain/snow to access
  • May need to run electricity for a workshop
  • Requires a large amount of yard space
  • May be restricted by homeowners association

That means when you sell the house, there is an added thirty five thousand dollars that the house can be sold for. This is for the standard, run of the mill garage.

Sometimes adding more intricate details like cabinetry, tandem garage design, specialty flooring, special painting or decorations runs the initial cost up while the return price stays as is, since these items are less important to the average buyer.
