Residential Solar / Photovoltaic (PV) Installation Permit in Unincorporated Yuma County, Arizona

Unincorporated Yuma County treats residential solar/PV installation as one of the Department of Development Services' Over-the-Counter (OTC) minor-project permit categories, alongside service clearance, water heater replacement, and A/C relocation/replacement — processed at the counter via the county's OTC Submittal Guide & Application rather than the full multi-week Residential Permit Guide review track. No distinct flat or per-watt solar fee line was found published separately from the general Building Permit Fee (Table No. 1-A, valuation-based) and Electrical Permit Fee (Table No. 3A) that this OTC permit is billed under (same fee attachments cited in the electrical-plumbing-mechanical-permit entry). Arizona's statewide solar-permitting statute, A.R.S. § 11-323, independently caps what the county may charge and constrains what the county may require on plans.

Tips

  • Residential solar/PV in unincorporated Yuma County goes through the Over-the-Counter minor-project pathway, not the full multi-week Residential Permit Guide process — bring the OTC Submittal Guide & Application to the counter rather than submitting a full plan set for standard review.
  • Arizona's statewide A.R.S. § 11-323 limits the county to charging only its actual cost of issuing/reviewing a solar permit, and bars a mandatory engineer's stamp on a single-family system's plans unless the county documents in writing why one is necessary — ask for a written cost breakdown if a quoted fee seems out of line with this cap.
  • This entry covers only the structural/PV-installation permit; confirm with DDS whether any separate electrical service-upgrade work needs its own permit beyond the OTC solar filing.
