Most homeowners, who like to add another bedroom are not aware of the basic building codes regarding bedrooms. Building codes for bedrooms are not the same as for kitchen, bathroom or family room. Any
bedroom must have an
emergency egress (window or door) directly to the outdoor. Therefor no screen enclosure or
sunroom can install behind the only egress to the bedroom. Also, the
entrance to a bedroom from another
bedroom is not
permeable. Of course any bedroom addition must have air conditioning and heat. Consult with an
experienced room addition contractor for all codes and zoning regulations regarding any type of addition to your home.
