What's Required in Tucson
- Get a Residential Addition/Alteration permit for any deck more than 30 inches above the ground or floor level.
- Get one for a lower deck too if it is over a basement or floor below, part of an accessible route or required exit, or inside a side or rear setback.
- Get a permit for any roof, pergola or cover over a deck or patio.
- Provide the signed contract showing the value of the work, which sets the building permit fee.
- Submit plans showing footings, framing and connections for plan review.
- Get special district review first in a Historic or Neighborhood Preservation Zone.
- File the Owner/Builder Affidavit if you will build it yourself; rentals require a licensed contractor.
Do you need a permit to build a deck in Tucson?
It depends on height and placement. The City of Tucson does not require a permit for a deck that meets all four of these tests: it is 30 inches or less above the ground, is not built over a basement or a floor below, is not part of an accessible route or required exit, and does not extend into the required side or rear setbacks. Fail any one of them and you need a Residential Addition/Alteration permit from Planning and Development Services (PDSD). Any deck more than 30 inches above the ground or floor level always needs a permit. Tucson's amendment to the 2024 building code writes decks into the flatwork exemption, which is where the low-deck rule comes from. Being attached to the house is not, by itself, the trigger.
Two things override the exemption. Inside a Historic or Neighborhood Preservation Zone, special district review applies. And putting a roof over the deck is a different project: a patio cover, pergola or any roof structure needs a permit no matter how low the deck is.
| What you are doing | City filing | Rule |
|---|---|---|
| Freestanding deck 30 inches or less, outside setbacks | No permit | Must also not be over a floor below or part of an exit |
| Low deck that reaches into a side or rear setback | Addition/Alteration permit | Setback encroachment removes the exemption |
| Deck more than 30 inches above grade | Addition/Alteration permit | Plans, plan review and inspections |
| Deck serving a required exit or accessible route | Addition/Alteration permit | Not exempt at any height |
| Adding a roof, pergola or shade cover | Addition/Alteration permit | Patio and porch coverings always need one |
| Any deck in an HPZ or NPZ | Permit + special district review | Historic review comes first |
How much does a Tucson deck permit cost?
The building portion of a permit is priced on project valuation. For additions and alterations PDSD asks for the signed contract showing the value of the work, and the fee schedule effective July 1, 2026 then applies. The building permit fee is $89.45 for the first $2,000 of value plus $22.95 per additional $1,000 up to $25,000, with values rounded up. Residential plan review adds 50% of the permit fee, and the digital filing fee is 1% of the total with an $18.54 minimum.
- $3,000 deck: $89.45 + $22.95 = $112.40; review $56.20; filing $18.54; about $187.
- $8,000 deck: $89.45 + 6 × $22.95 = $227.15; review $113.58; filing $18.54; about $359.
- $15,000 deck: $89.45 + 13 × $22.95 = $387.80; review $193.90; filing $18.54; about $600.
Lighting or outlets on the deck are trade work: $150 for the first item and $50 for each additional item. Starting work without the required permit costs a penalty equal to 100% of the permit fee.
Footings and structure
Tucson's amendment to the residential code sets the local frost line depth at 0, so footing depth comes from the structural design and soil, not a frost rule. The city also adds microburst uplift-connection requirements to roof framing, which matters if the deck carries a roof. Residential alterations sit in the Standard Lane, which has a 30-day review goal, and an issued permit expires if 365 days pass without a recorded inspection showing progress.
How to Get a Deck Permit in Tucson
Step 1: Run the four exemption tests
Check the deck height, whether there is a floor below, exit or accessible-route use, and the setback lines. If all four pass and you are outside a preservation zone, no permit is needed.
Step 2: Prepare plans and contract value
Draw the site plan and the structural details. Have the signed contract or a written valuation ready for the fee.
Step 3: Apply in TDC Online
File a Residential Addition/Alteration permit and pay the review fee, which is collected before review starts.
Step 4: Plan review
Residential alterations are in the Standard Lane, with a 30-day review goal. Pay the balance of the fees at approval.
Step 5: Build and inspect
Call for inspections before covering footings and framing. The permit expires if 365 days pass without a recorded inspection showing progress.
