Shed permit in Smyrna, TN
It depends — some shed work in Smyrna needs a permit, some doesn't.
A detached one-story accessory building needs a permit if its floor area is over 100 sq ft.
| Permit needed? | Depends on size |
|---|---|
| Where the line falls | Over 100 sq ft |
| Fee | Not in the ordinance — the department quotes it |
| Review time | Not in the ordinance |
| Code section | IRC R105.2 item 1 (§ 12-602) |
| Based on | IRC 2024 as amended |
Most building codes exempt a shed up to 200 sq ft. Smyrna is stricter — the cutoff here is just 100 sq ft.
How to pull the permit
- Put together a site plan showing where the work goes, with dimensions.
- Apply through the Smyrna building department.
- Pay the permit fee when the permit is issued. Work done before that isn't covered.
- Book each inspection listed on the permit as the job reaches that stage.
If you skip it
Building without a required permit is unlawful and punishable under the general penalty provision; each day is a separate offense.

Questions people ask
My shed 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.
