Permits & code in Arizona
Sheds under 120 sq ft are typically permit-exempt at the state level. Setbacks from property lines still apply.
State-level rules only — cities and HOAs frequently add stricter requirements. Always confirm with your local building department before you dig.
What most people get wrong
- Skimping on the foundation. A skid on bare dirt sags in two seasons.
- Skipping the drip edge. Water siphons under shingles and rots the sheathing.
- Framing walls at 24" OC when siding manufacturer specifies 16".
The 5-step shed plan
- Step 1Confirm site and permit pathLocate property lines, call 811 for utility marking, and check whether your city/HOA needs approval before you break ground.
- Step 2Order materialsUse the shopping list from our planner. Confirm delivery vs pickup — bulk lumber and concrete are usually cheaper delivered.
- Step 3Lay out and prep the siteBatter boards, string lines, level the base. Getting this right saves days later.
- Step 4Frame the structureFollow the cut list. Check for square with the 3-4-5 method every few pieces. Fasten with the right structural screws.
- Step 5Finish and inspectSand, stain/seal, and (if required) schedule your final inspection before backfilling or closing anything up.
