Hi again, 4space!
If a garage is connected to a house, and there is no open space between the two (i.e. a car port), it would be considered in the overall floorplan. If a birds' eye view shows it to be a continuation of the total footprint it would be included in your layout calculations.If it butts out beyond the residential portion, the question as to whether it would be included when doing your layout would depend on whether it is less or more than 1/3 of the total dimension of the face you are looking at. If it is less than a third, it would be a projection. If it is more than a third, then you would have a missing area immediately adjacent to it.
All the best!
Wendy
