building architect

a permit to open to get a back door Good morning, what I need is a licensed architect. I have the blueprints for my house but it does not include it in the back door or the bathroom that's in the basement which is an addition to what's on the house now for the city that I live in I want to put a back door in the basement so where someone could exit through. the blue print need for back door with the bathroom there I would have to put in a permit to get the back door to get permit to license.
