Building permits in Pima County — the 2nd most populous county in Arizona, home to Tucson and the Sonoran Desert — are issued by Development Services Department, Building & Site Development Division. Pima County enforces the 2018 IBC/IRC with Pima County amendments.
This guide covers what requires a permit, the Accela Portal, fees, trade permits, and inspections — so your Pima County project stays on track.
Southern Arizona's largest county, home to Tucson and iconic Sonoran Desert landscapes. Pima County Development Services handles permitting for unincorporated areas only. Properties within Tucson, Oro Valley, Marana, or Sahuarita are permitted by those municipalities. Dark-sky ordinances and desert conservation overlay zones may affect projects. All contractors must hold an active Arizona ROC license.
Jurisdiction note. Pima County permits cover unincorporated areas only. If your project is within an incorporated city or town, contact that municipality's building department.
What requires a building permit in Pima County?
Under the 2018 IBC/IRC with Pima County amendments, a permit is required for most construction activities:
Permit required
- New residential and commercial construction, additions
- Structural and load-bearing alterations
- Reroofing, windows, siding, and exterior changes
- Electrical service changes and most wiring work
- HVAC installations and changeouts
- Plumbing alterations, repipes, and water heaters

Exemptions are narrow and scope-specific. When unsure, confirm with the building department before starting — see the penalty note below.
Get the permit issued before starting work. Building without one exposes the owner to penalties and stop-work orders. Note that exemption from a building permit does not exempt a project from zoning requirements — confirm edge cases with the building department.

Pima County trade permits
Electrical, plumbing, and mechanical work each needs its own permit and an Arizona ROC-licensed contractor in the appropriate specialty classification.
Electrical permits
Required for service installations, panel upgrades, solar PV, EV chargers, and most wiring alterations — performed by an ROC-licensed electrical contractor (C-11/R-11 classification).
Plumbing permits
Required for new plumbing, repipes, water heater changeouts, fixtures, backflow, and sewer connections — performed by an ROC-licensed plumbing contractor (C-37/R-37 classification).
Mechanical (HVAC) permits
Required for HVAC installations, changeouts, ductwork changes, and venting modifications — performed by an ROC-licensed mechanical contractor (C-39/R-39 classification).
Miscellaneous & specialty
Fencing, pools, decks, sheds, and patio covers may require special permits depending on size and utility hookups. Demolition, sign, and right-of-way permits follow separate tracks.
Verify your contractor's ROC license. Arizona licenses contractors through the Registrar of Contractors (ROC) — a contractor's license is required for any work totaling $1,000+ (labor and materials) or any work that requires a building permit, regardless of cost. Arizona uses a classification system with 60+ license types across Residential (R-), Commercial (C-), and Dual (KB/CR) categories. Property owners may act as their own general contractor on an owner-occupied residence under A.R.S. § 32-1121(B), subject to restrictions. Verify contractor licensure at roc.az.gov.
