I want to enclose an open-air porch with sliding glass doors and Pierce County says I need a building permit that will include "a building plan - dimensioned and drawn to scale showing a floor plan of the layout and providing details on how the wall will be built and attached to the floor, roof and posts." There are two exposed sides (see plot plan) to the porch. I want to close-in each of the two sides with (2) sliding glass doors per side. This will require a little framing to position the doors within the 17'11" opening on each side. What would you charge me to produce the drawing? You would be getting dimensions etc from the glass/door company who will be doing the installation.
