Shed permit in Mesa, AZ
It depends — some shed work in Mesa needs a permit, some doesn't.
You do not need a building permit for a one-story detached shed of 200 square feet or less used for tools, storage, a playhouse, or a similar use, as long as it goes with a home. You do need a permit once the floor area passes 200 square feet, and also if your lot falls under the Desert Uplands Development Standards, sits in a Historic Preservation Overlay District, or is a designated historic landmark. Zoning setback rules for detached accessory buildings still apply, and the roof must not overhang the property line or drain onto your neighbor.

How to pull the permit
- Put together a site plan showing where the work goes, with dimensions.
- Apply through the Mesa 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
Mesa'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?
Mesa 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.
