Remodeling a Kitchen
Q: I would like to enlarge my kitchen by bumping out the exterior wall. How would the floor joists from the floor above be supported now that there is no structural wall for them to sit on?
I understand some sort of beam would be required. Would it be as simple as replacing the rim joist with a beam and then hanging the joists on joist hangers?
A: Although it may be acceptable to hang joists from a beam
with the proper hangers, it is essential that the beam be sized properly. Since there are also other structural considerations, such as the presence of existing shear walls that may need to be evaluated, you need to consult with a licensed general contractor or structural engineer to decide the best way to do it. Also, your building department will require the stamp of a professional on the blueprints you must submit to obtain a building permit for such a project.
