What's Required in Mesa

  • Building permit required if the shed exceeds 200 square feet.
  • Zoning review required for all sheds regardless of size.

  • Must maintain a minimum setback (usually 3-5ft) from property lines.

What Size Shed Needs a Permit in Mesa

Whether you need a building permit for a shed in Mesa usually comes down to size. In Mesa, the cutoff is 200 square feet: a simple one-story shed at or under that size generally doesn’t need a building permit, while anything that exceeds it does. A popular 10x12 shed (120 sq ft) comes in under the limit, so it typically doesn’t need a building permit. Larger sheds, and any shed with electrical, plumbing, or a permanent foundation, almost always need a permit regardless of footprint.

Building a Shed Without a Permit in Mesa

Even when a shed is small enough to skip a building permit in Mesa, “no permit” doesn’t mean “no rules.” A permit-exempt shed generally must stay at or under the 200-square-foot limit, sit on a non-permanent base (sheds on skids or a gravel pad are treated more leniently than those on a poured foundation), and have no electrical or plumbing run to it. Crucially, zoning setbacks still apply — your shed usually has to sit a minimum distance from property lines and other structures, and that holds even for a permit-free shed. Confirm both the size exemption and the setback distance with the Development Services - Building Safety before you build.

Frequently Asked Questions

No building permit is needed, but a zoning review is required.
No, accessory structures must be in the rear or side yard.
Permitted sheds must be anchored to a stable base or foundation.
In Mesa, you can build a shed up to 200 square feet without a building permit; anything over that needs one. The exemption usually also requires no permanent foundation and no electrical or plumbing, and zoning setbacks from property lines still apply even without a permit.
Often not, if it’s also within Mesa’s 200 sq ft limit and has no utilities — many jurisdictions treat a shed on skids or a gravel pad as movable rather than a permanent building. A poured foundation or any electrical/plumbing typically triggers a permit. Confirm with the Development Services - Building Safety; zoning setbacks apply either way.
