Garage permit in Mesa, AZ
Yes — you need a permit for garage work in Mesa.
Building a garage needs a building permit. An attached garage is an addition to the dwelling, so it is built to the requirements for new construction (4-3-2(H)) and is not exempt. A detached garage is an accessory structure, but Mesa's only building-permit exemption for detached accessory structures (4-1-4(B)(1)(a)) covers one-story tool/storage sheds, playhouses and similar uses of 200 square feet or less - a garage is neither that use nor typically under 200 sq ft, so it falls outside the exemption. Either way a permit is required.

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.
Either of you can pull it. When a contractor does the work, it is normally their job.
If you skip it
Doing work without a required permit triggers a separate permit at regular fees plus an investigation fee (4-1-8); Chapter 4 violations are subject to the penalties in 4-1-9.

How much does a garage permit cost in Mesa?
The code does not print a dollar amount. Fees come from the City of Mesa fee schedule (4-1-8); an investigation fee applies to work started without a permit.. 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?
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.
