How to apply in Mesa
In Mesa, a residential shed permit application, once the shed is large enough to require one, is a set of construction documents that show what will be built and prove it meets the adopted residential code. In practice that means a written permit application, a scaled site plan locating the shed and its distances to the property lines, and construction documents covering the shed's foundation or anchoring system and its framing.
What most shed permit applications include:
- For Mesa, a written permit application identifying the proposed work and describing the property by its address or legal description, filed with the building department before construction begins (IRC R105.3).
- For Mesa, a scaled site plan showing the shed's size and location and its dimensioned distances to all property lines so required setbacks can be verified before the permit is issued (IRC R106.2).
- Construction documents showing the shed's foundation: freestanding accessory structures at or under the code's small-structure size and eave-height limits (600 square feet and a 10 foot eave height in the model code) are exempt from continuous footings but must still be shown supported on undisturbed soil or engineered fill and anchored to resist wind-induced uplift and overturning (IRC R403.1).
- Where the shed does sit on a continuous foundation with a wood sill plate, anchor bolt or approved strap details tying the sill plate to the foundation (IRC R403.1.6).
- Roof framing details showing the rafter-to-wall or truss-to-wall connections, since even a shed exempt from continuous footings must be anchored to resist wind-induced uplift and overturning (IRC R403.1; R802.11).

Inspections and closing out your permit
In Mesa, a permitted shed is inspected in stages as it goes up: the foundation or the anchors that hold it down before they are covered, the framing before it is enclosed, and a final inspection once the shed is finished. Each stage checks the items that would be hidden or unsafe if skipped.
- Foundation or anchor inspection in Mesa: called after any required footings, piers, or ground anchors are set and any forms or reinforcing steel are in place, but before concrete is placed, so the foundation or anchoring system can be verified before it is covered (IRC R109.1.1).
- Frame inspection in Mesa: after the shed is framed, sheathed, and braced, the inspector checks the framing, bracing, fasteners, and the roof connections that resist wind uplift, before those elements are covered (IRC R109.1.4 frame inspection; R403.1 anchorage).
- Final inspection in Mesa: made after the permitted work is complete and before the shed is used; work may not proceed past any inspection stage without the building official's approval (IRC R109.1.6 final inspection; R109.4 approval required).
- In Mesa: for a pre-fabricated or kit shed, the manufacturer's installation instructions must be on site at the time of inspection so the inspector can confirm the anchoring and assembly match the design (IRC R106.1.2).
Schedule each inspection in advance and pass the final before you use the work or close the permit. Request inspections through the Mesa permit portal or by phone at 480-644-4273.

- Can a homeowner pull a shed permit themselves in Mesa?
- Under Arizona law (A.R.S. 32-1121(A)(5), (A)(9), (A)(14)(a); 32-1164(A)(2), (B)): Arizona addresses owner-builders through its contractor licensing law rather than through the building code itself. A.R.S. 32-1121(A)(5) exempts property owners who build or improve structures on their own land and do the work themselves, with their own employees, or with duly licensed contractors, as long as the finished structure is for the owner's own occupancy and is not intended for sale or rent. Selling or renting within one year of completion or of the certificate of occupancy is prima facie evidence the project was really undertaken for sale or rent, which defeats the exemption, a rule that functions much like Florida's one-year restriction. The exemption does not waive the underlying permit requirement: several of the chapter's small-job licensing exemptions, including the $1,000 casual-work exemption in A.R.S. 32-1121(A)(14), expressly do not apply whenever the work requires a local building permit, so once a job needs a permit, anyone doing that work for someone else generally must hold an Arizona contractor's license regardless of dollar amount. Acting as a contractor without a license, on permit-required work or otherwise, is a class 1 misdemeanor under A.R.S. 32-1164, carrying a mandatory minimum fine of $1,000 for a first offense and $2,000 for a repeat offense.
