County-Specific Requirement
TEP requires a pre-application notification call at (520) 623-7711 before permit submission. You will receive a TEP project number — include it on your permit application. Systems over 10kW require an Arizona-licensed engineer stamp on the single-line diagram.
Required Documents
- Completed permit application — from Pima County Development Services
- Site plan / plot plan — showing panel location, setbacks, north arrow, scale
- Roof plan with panel layout — including IFC fire setback dimensions
- Single-line electrical diagram (SLD) — signed by installer
- Equipment specification sheets — panels, inverter, racking
- Structural engineering letter — required for systems over 10kW in most jurisdictions
- Permit fee — $200–$500 (verify current fee schedule with AHJ)
Interconnection: Tucson Electric Power (TEP)
TEP interconnection has a longer timeline than APS/SRP — submit the TEP application simultaneously with your county permit to minimize total wait. TEP's Renewable Energy program is at tep.com.

File your Tucson Electric Power (TEP) interconnection application at the same time as your county permit application. Both reviews run in parallel, saving 3–6 weeks off your total timeline to Permission to Operate.

Frequently Asked Questions
Contact Pima County Development Services at (520) 724-9000 or use their online portal to schedule inspections. Your installer typically schedules inspections on your behalf. Inspections are generally available within 1–5 business days of scheduling, depending on the AHJ's workload. Confirm the inspection type (rough-in vs. final) and access requirements with your installer before the scheduled date.
The most common causes: incomplete application documents (missing SLD or spec sheets), plan revisions required by the AHJ (often fire setback issues), and utility interconnection queue delays. Submitting a complete, accurate package the first time and filing the Tucson Electric Power (TEP) interconnection application simultaneously with the county permit are the two most effective delay-reduction strategies.
A properly permitted and inspected solar installation is generally covered under your homeowner's policy as a permanent home improvement. Notify your insurer after installation is complete and PTO is issued — some require a rider or endorsement for solar. Unpermitted installations may void coverage for fire or weather damage.
