My boring residential attached garage is about 19ft x 19ft, 19 ft high. It is about 9 feet below the first floor grade. There is a set of wooden stairs inside the garage leading up to the first floor through a typical exterior metal door. I really want to add a second floor, a sort of 'work platform' or 'loft'. Maybe 2/3 the area of the floor below. The main structural component is to be a 20ft I-beam right across the middle. I had my beam/joist plan documented and stamped by an engineer.
Here's my problem - My county permit office wants to treat it like a finished space addition. This requires
- completely walling the new '2nd floor' off from the first, including walling the stairs into a 'stair well' and a new door from that stairwell
- Adding a window to outside and yet another door into the house (2x egress)
- Drywalling in all the joists.
How can I alter my design to avoid these extra features, especially stairwell and extra doors? My original idea was just to add a platform and add a few stairs off the existing landing to get to it. Simple, cheap. I imagined a wooden railing on the edge, like you'd see on a deck. I don't want to fool with points of egress. I don't even need stairs if that simplifies things.
