Quick answer
Tucson requires a Solar permit to install a solar panel system or a backup generator connected to the home's electrical service. Licensed solar contractors can use SolarAPP+ for same-day review of roof-mounted residential systems outside Historic and Neighborhood Preservation Zones; other projects go through the 30-day review in TDC Online. A structure the panels mount on must already be legal and permitted.
Who is pulling this permit?
Apply yourself
Hire it out
Before you sign, ask the contractor:
- Who pulls the permit, you or me, and is the permit fee included in the bid?
- Which inspections will this job need, and who meets the inspector on site?
- Is your Arizona Registrar of Contractors license active, and under which business name? Verify it on roc.az.gov.
Arizona's owner-builder rule (A.R.S. 32-1121(A)(5), (A)(9), (A)(14)(a); 32-1164(A)(2), (B)) sets what you may do on your own home without hiring anyone. Read the statute.

How to apply in Tucson
In Tucson, a rooftop solar PV permit application is a combined structural and electrical plan set: a site plan and roof framing details proving the array's mounting can carry its added loads, plus a one line electrical diagram covering listed modules and inverters, disconnects, and the rapid shutdown design. Utility interconnection is a separate approval that runs in parallel with the permit.
What most solar permit applications include:
- Both a building permit and a separate electrical permit are required, since the array must be designed and installed to the residential code's solar provisions and to the National Electrical Code (IRC R324.3).
- For Tucson, the plan set identifies listed equipment: PV modules listed to UL 1703 (or both UL 61730-1 and UL 61730-2), and inverters listed to UL 1741, with grid-tied inverters listed for utility interaction (IRC R324.3.1).
- Structural drawings show that the roof framing is designed to structurally support the array and withstand the gravity loads it adds (IRC R324.4.1).
- For Tucson, the site plan lays out roof access pathways at least 36 inches wide, plus a ridge setback sized to how much of the roof the array covers, so firefighters retain pathways and ventilation access (IRC R324.6.1, IRC R324.6.2).
- For Tucson, the one line electrical diagram shows the rapid shutdown method and the location of its single initiation device, since one control point must bring all system conductors down to safe levels (NEC 690.12, NEC 690.56(C)).
- Interconnecting the array to the utility grid at a defined point of connection is a separate application process from the local building or electrical permit and must be approved before the system can operate (NEC 705.12).
- Some permitting offices route applications through SolarAPP+, an automated review platform that checks the plan set against code requirements and issues eligible permits instantly (DOE SolarAPP+).

Inspections and closing out your permit
In Tucson, inspectors verify the installed array against the approved plans, and some agencies run a rough check of roof attachments and penetrations while they are still exposed before the wiring and roofing close them in. The final inspection confirms rapid shutdown, disconnects, grounding, and required labels are installed correctly, and the system cannot be energized until the utility separately approves interconnection.
- In Tucson: where an agency runs a rough or pre-inspection, it checks the array's roof penetrations while they are still exposed, confirming they are flashed and sealed (IRC R324.4.3).
- In Tucson: the inspector confirms whether rapid shutdown is required, how it is accomplished, and that it is properly identified (NEC 690.12, NEC 690.56(C)).
- In Tucson: pV disconnecting means must be permanently marked and installed where they are readily accessible, which the inspector confirms in the field (NEC 690.13).
- In Tucson: bonding and grounding of the array, including every exposed non current carrying metal part and the grounding electrode system, is checked before sign off (NEC 690.43, NEC 690.47).
- In Tucson: at the service equipment, the inspector looks for the required rapid shutdown placard, a labeled diagram showing the initiation device's location in the specified colors and letter sizes (NEC 690.56(C)).
- In Tucson: utility interconnection is inspected and approved separately from the local building department's sign off, and the system cannot be energized until both approvals are in hand (NEC 705.12).
Schedule each inspection in advance and pass the final before you use the work or close the permit. Request inspections through the Tucson permit portal or by phone at (520) 791-5550.

- How long does a solar permit take in Tucson?
- Express Lane, same-day for SolarAPP+ applications; Standard Lane, 30-day review target for non-SolarApp solar (Permit Review Lanes). Times can vary by workload and project scope, so confirm with the office.
- Where do you apply for a solar permit in Tucson?
- You can apply through the Tucson permit portal or contact the City of Tucson Planning and Development Services Department (PDSD) directly. The links are listed on this page.
- Can a homeowner pull a solar permit themselves in Tucson?
- Under Arizona law (A.R.S. 32-1121(A)(5), (A)(9), (A)(14)(a); 32-1164(A)(2), (B)): Arizona addresses owner-builders through its contractor licensing law rather than through the building code itself. A.R.S. 32-1121(A)(5) exempts property owners who build or improve structures on their own land and do the work themselves, with their own employees, or with duly licensed contractors, as long as the finished structure is for the owner's own occupancy and is not intended for sale or rent. Selling or renting within one year of completion or of the certificate of occupancy is prima facie evidence the project was really undertaken for sale or rent, which defeats the exemption, a rule that functions much like Florida's one-year restriction. The exemption does not waive the underlying permit requirement: several of the chapter's small-job licensing exemptions, including the $1,000 casual-work exemption in A.R.S. 32-1121(A)(14), expressly do not apply whenever the work requires a local building permit, so once a job needs a permit, anyone doing that work for someone else generally must hold an Arizona contractor's license regardless of dollar amount. Acting as a contractor without a license, on permit-required work or otherwise, is a class 1 misdemeanor under A.R.S. 32-1164, carrying a mandatory minimum fine of $1,000 for a first offense and $2,000 for a repeat offense.
