Questions people ask

How much does a basement permit cost in Knoxville?

Per Fee Schedule adopted by City Council resolution. Valuation-based fees mean the number depends on what the job is worth, so the department quotes it when you apply.

I already built it without a permit. What now?

Knoxville 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.
