Building Permits in Tucson

Tucson requires a building permit for most construction, alteration, and repair work that affects structural, electrical, plumbing, or mechanical systems. Permits are issued by the City of Tucson Planning and Development Services Department (PDSD), which administers zoning, plan review, inspections, and code enforcement for properties within Tucson city limits.

Tucson has adopted the 2018 International Building Code (IBC), 2018 International Residential Code (IRC), 2018 International Mechanical Code (IMC), 2018 International Plumbing Code (IPC), 2018 International Energy Conservation Code (IECC), and the National Electrical Code (NEC) — all with local Tucson amendments. Zoning is governed by the Tucson Unified Development Code (UDC). Arizona has no mandatory statewide building code; each municipality adopts and amends codes independently.

Properties outside Tucson city limits in unincorporated Pima County must use Pima County Development Services, not PDSD.

When You Need a Permit

You generally need a Tucson building permit for:

• New construction, additions, and accessory structures including ADUs (Accessory Dwelling Units)
• Structural alterations, load-bearing wall changes, and foundation work
• Electrical, plumbing, and mechanical (HVAC) changes
• Reroofing and window or door openings in exterior walls
• Swimming pools, spas, and retaining walls above a height threshold
• Solar photovoltaic (PV) installations
• Demolition of any habitable structure

Minor cosmetic work (painting, floor coverings, cabinetry without plumbing or electrical changes) is typically exempt. When in doubt, contact PDSD before starting work.

TDC Online — The Permit Portal

TDC Online (Tucson Development Center Online) at tdc-online.tucsonaz.gov is the City of Tucson's primary online permit portal. It allows applicants to:

• Create an account and submit permit applications
• Upload plans for electronic plan review
• Respond to correction comments without visiting the office
• Pay permit fees online
• Request and track inspections
• Download approved permits and inspection records

The portal is available 24/7. In-person service is available at PDSD at 201 N. Stone Ave., Tucson, AZ 85701. For general permit questions, contact PDSD at (520) 791-5550.

Permit Costs

Tucson permit fees are established in the PDSD Fee Schedule published by the Planning and Development Services Department. Fees are typically calculated based on:

• Building permit fee — scales with project valuation
• Plan review fee — a percentage of the building permit fee
• Impact fees — for new construction or added square footage (transportation, water, wastewater, parks)
• Trade permit fees — electrical, plumbing, mechanical permits

Do not rely on third-party fee estimates. Always check the current Tucson PDSD Fee Schedule linked in the sources above for exact amounts.

Typical Timeline

Turnaround times fluctuate with PDSD workload. Contact PDSD or check TDC Online for current estimates before planning your project schedule.

The Process

1. Pre-submittal: Confirm zoning, overlays, and applicable UDC requirements for your parcel using Tucson's zoning map
2. Plans: Prepare drawings stamped by a licensed Arizona architect or engineer where required by code
3. Submit via TDC Online: Create an account and upload documents for electronic plan review
4. Plan review: PDSD disciplines (building, structural, electrical, mechanical, plumbing, zoning, fire, civil) review the plans
5. Corrections: Respond to review comments in TDC Online and resubmit revised plans
6. Permit issuance: Pay remaining fees and download the approved permit from TDC Online
7. Inspections: Schedule required inspections at each construction phase through TDC Online
8. Final: Pass the final inspection and, where applicable, receive a Certificate of Occupancy

Inspections

Typical inspection stages for a residential project in Tucson include:

• Footing / foundation
• Underground plumbing and electrical
• Framing
• Rough plumbing, electrical, and mechanical
• Insulation
• Drywall
• Final building and trade inspections

Schedule inspections through TDC Online or by contacting PDSD at (520) 791-5550. Confirm cutoff times for next-business-day scheduling with PDSD, as procedures may change.

Common Reasons for Denial or Corrections

• Plans don't meet the Tucson-adopted building codes or local amendments
• Missing structural calculations, energy compliance documentation (IECC), or design-professional stamps
• Zoning conflicts under the Tucson UDC (setbacks, height, lot coverage, permitted use)
• Missing civil or site review items (drainage, right-of-way, water/wastewater clearances)
• Historic preservation or overlay district review not completed
• Incomplete submittal or missing documents in TDC Online
