Shed permit in McKinney, TX
It depends — some shed work in McKinney needs a permit, some doesn't.
A one-story detached accessory building of 200 square feet or less does not need a building permit. A larger shed, or one that is not detached and one-story, does need a permit.
| Permit needed? | Depends on size |
|---|---|
| Where the line falls | Over 200 sq ft |
| Fee | Not in the ordinance — the department quotes it |
| Review time | Not in the ordinance |
| Code section | IRC R105.2 |

How to pull the permit
- Put together a site plan showing where the work goes, with dimensions.
- Apply through the McKinney 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.
Either of you can pull it. When a contractor does the work, it is normally their job.
If you skip it
McKinney's code doesn't set a specific fine for this work. In practice the department can issue a stop-work order, and unpermitted work tends to surface during a sale, when the buyer's inspector or the title company asks for it.

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?
McKinney 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.
