My basement ceiling joists are exactly 7 feet above the concrete slab. The requirement for finished living space is 7 ft from the finished floor to the finished ceiling. Since I'll loose a couple of inches with the flooring (I'll have Delta-FL drainboard + laminate) and the ceiling (drywall), essentially I won't have enough height to meet the requirement.
I'm quoting from what I think is my local code (pdf):
R305.1 (Amended). Habitable space, hallways, corridors, bathrooms, toilet rooms, laundry rooms and portions of basements containing these spaces shall have a ceiling height of not less than 7 feet. The required height shall be measured from the finished floor to the lowest projection of the ceiling. Not more than 50% of the floor area of a room or space is permitted to have a sloped ceiling less than 7 feet in height.
Question: what can I do about this? One idea I had was to put the drywall between the joists rather than below them perhaps just a few inches above the lower end to compensate for this. Would this fly? Has anyone done anything like that? I realize that this is going to be a lot more work but I may be willing to do it. Any other ideas?
