Questions people ask
My garage is right at the limit. Does that count?
The exemption has to fit exactly — if the code says a size or height, being at or under it keeps you exempt, and going a single inch over doesn't. When you're close to the line, measure before you buy materials, and call the department if the number is borderline.
I already built it without a permit. What now?
Smyrna can issue a stop-work order and require you to apply after the fact, sometimes with an extra fee. Work that was covered up may have to be opened for inspection. Full walkthrough here.
Does unpermitted work cause problems when selling the house?
Often, yes. A buyer's inspector or the title company may flag it, and lenders can balk at financing a home with open or missing permits. What to do about it.
