How to apply in Maricopa County
In Maricopa County, a residential deck permit application is a set of construction documents that show what will be built and prove it meets the IRC deck provisions. In practice that means a scaled site plan locating the deck and its setbacks, plus deck plans and structural details covering the footings, posts, beams, joists, ledger, guards, and stairs.
What most deck permit applications include:
- For Maricopa County, a permit application identifying the work, the deck's size (square footage), and whether electrical work such as lights or receptacles is included, submitted for plan review before construction begins (IRC R106).
- For Maricopa County, a scaled site plan (for example 1/4 inch to 1 foot) showing the new deck's location relative to the house, its overall length and width, and dimensioned distances from the deck to all property lines and other structures so required setbacks can be verified (IRC R106.1.1).
- For Maricopa County, a deck plan drawn to scale showing overall dimensions and the framing layout: joist size, spacing, span, and species; beam size and span; post size and height; and footing or pier size and depth (IRC R507.4 posts, R507.5 beams, R507.6 joists, R507.3 footings).
- For Maricopa County, a section or side elevation with connection details showing the ledger attachment to the house band joist with flashing, the fastener or bolt schedule, joist hangers, post-to-beam and post-to-footing connections, and the required lateral load connection (IRC R507.9 ledger connection, R507.9.2 lateral connection, R507.2.4 flashing).
- Footing sizing derived from tributary area, the soil bearing value, and design loads per IRC Table R507.3.1, with footings shown bearing on undisturbed soil at the frost depth required by the jurisdiction (IRC R507.3).
- Details for the guards required where the walking surface is more than 30 inches above grade, and for the stairs and handrails, showing guard height and opening limits, stair riser and tread dimensions, and handrail location (IRC R312 guards, R311.7 stairs and handrails).
- For designs that fall outside the prescriptive R507 tables (for example multi-story or stacked decks, or a ledger attached to a cantilever), engineered and stamped structural plans are submitted in place of the prescriptive details (IRC R507.1 and R301).

- Footing or pier inspection in Maricopa County: after the holes are dug and any forms or reinforcing are set but before concrete is placed, the inspector checks footing depth and diameter, a flat undisturbed bearing surface, and that the holes are free of water (IRC R109.1.1 foundation inspection; R507.3 footings).

- Can a homeowner pull a deck permit themselves in Maricopa County?
- 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.
