Do you need a building permit in Arizona?
Usually it depends on the size of the job, and the size that decides it is not set by Arizona: permits are issued by the city or county, not the state, so the rule that governs your project is the one your own jurisdiction publishes. 33 of those local rules require a permit outright, 47 depend on a size or scope condition the office publishes, and 0 need none. Arizona sets the building code those local rules derive from; your city or county sets the threshold and the fee.
Do Arizona jurisdictions agree?
Every row below is a measurement at least two Arizona jurisdictions publish, compared against each other. This is the question a statewide answer cannot settle, because the number that governs your project is the one your own city or county publishes.
| Project | Published threshold | Jurisdictions | Agreement |
|---|---|---|---|
| Fence | 1 to 7 feet | 8 | 4 different numbers |
| Shed | 120 to 200 sq ft | 8 | 2 different numbers |
| Deck | 30 inches | 3 | Same number in all 3 |
| Patio | 30 inches | 2 | Same number in all 2 |
| Pool | 18 inches | 2 | Same number in all 2 |
3 of 5 comparable measurements are uniform across Arizona; 2 are not. Latest verification 2026-07-19.
Where Arizona jurisdictions split
The verdict for each project across the 8 Arizona jurisdictions we cover. On 7 of 10 projects they do not give the same answer, which is why a statewide answer is not one.
| Project | Permit required | Depends | No permit | Across the state |
|---|---|---|---|---|
| Deck | 3 | 5 | Answer varies | |
| Electrical | 5 | 3 | Answer varies | |
| HVAC | 5 | 3 | Answer varies | |
| Patio | 2 | 6 | Answer varies | |
| Plumbing | 5 | 3 | Answer varies | |
| Pool | 6 | 2 | Answer varies | |
| Solar | 7 | 1 | Answer varies | |
| Fence | 8 | Same answer everywhere | ||
| Roof Replacement | 8 | Same answer everywhere | ||
| Shed | 8 | Same answer everywhere |
Building without a permit in Arizona
Arizona has no state agency that issues building permits and no single statewide crime for building without one. State law instead authorizes cities to adopt and enforce their own codes as ordinances (A.R.S. Title 9) and counties to do the same in zoned unincorporated areas (A.R.S. Title 11), with municipal zoning and permit rules enforced the same way as any other city ordinance under A.R.S. 9-462.05.
Penalties, the as-built path, and what the statute actually says
What you can build without a permit in Arizona
0 of the 80 answered rules across Arizona need no permit at all and 47 turn on a size or scope condition the jurisdiction publishes, by project and jurisdiction, in each office's own words.
What a permit costs in Arizona
There is no single Arizona permit fee. Each jurisdiction in Arizona sets and publishes its own, and they do not use the same pricing model, so the figure that applies to your project is the one your own city or county publishes. Below is every Arizona project where we have quoted one, verbatim, from the office's own schedule.
| Project in Arizona | Jurisdictions publishing a fee |
|---|---|
| Electrical | 7 |
| Fence | 7 |
| HVAC | 7 |
| Plumbing | 7 |
| Shed | 7 |
| Deck | 6 |
| Patio | 6 |
| Pool | 6 |
| Solar | 6 |
| Roof Replacement | 4 |
Each row links to the Arizona table carrying every quoted fee, its source and its verification date. We do not publish a Arizona average: the notes mix flat minimums, valuation percentages and per-fixture charges, so an average would be a number no office charges.
Building code in Arizona
No statewide building code; adopted locally. Counties and cities adopt their own codes, typically a version of the International Residential Code (IRC).
Administered by Local county or city building department.
Arizona has no statewide building code. Requirements are set by each jurisdiction.
Most local permit thresholds derive from this code. See our sources and standards.
What each Arizona jurisdiction publishes
