Fee schedule

Residential/Commercial Solar Photovoltaic (PV) Permit
VerifiedRequired for installation of a rooftop or ground-mounted solar photovoltaic system within Thatcher town limits. The Town's own iWorq Citizen Portal application flow explicitly names 'Solar' as one of its listed permit categories, alongside Electrical, Gas, and Plumbing (thatcherpermitting.portal.iworq.net/THATCHER/new-permit/600/4632) — confirming solar is a genuine, distinct application category rather than folded silently into the general electrical permit. However, consistent with every other permit type in this file, Thatcher has NO fixed, published dollar-figure fee for solar — Code of Ordinances § 150.98 states all fees are set by separate Town Council resolution, and no such resolution document was located online as of this review. Arizona statute A.R.S. § 9-468 independently caps whatever fee is actually charged at the Town's actual cost of issuing the permit.
Verified 2026-07-20 · Source
Requirements
- Solar PV installation requires a permit submitted via the iWorq Citizen Portal's combined 'Solar, Electrical, Gas or Plumbing permit' application (thatcherpermitting.portal.iworq.net/THATCHER/new-permit/600/4632), selecting Solar as the work type
- Governed by the 2015 IBC/IRC (structural mounting) and 2014 NEC (electrical interconnection) as adopted by the Town — see codesAdopted
- Per A.R.S. § 9-468(A), the Town may not require a professional engineer's stamp on a standard residential rooftop PV system absent a written, installation-specific finding of necessity
- Per A.R.S. § 9-468(D)-(F), any fee the Town actually assesses 'shall not exceed the actual cost of issuing the permit,' and the Town must hold a public hearing with at least 15 days' notice before adopting or changing a solar-specific fee
- Site Plan Review Checklist (2 D-size copies) required with the building plans and permit application, per the same general submittal framework documented in this file's Residential Building Permit entry
Required documents
- RequirediWorq Citizen Portal Permit Application (Solar, Electrical, Gas or Plumbing)Online application at thatcherpermitting.portal.iworq.net/THATCHER/new-permit/600/4632, with 'Solar' selectable as its own work type

Confirmed gap after exhaustive chase (Code of Ordinances, Document Center, Forms Center, Wayback Machine) — the same gap already documented for every other permit type in this file. A.R.S. § 9-468(D) independently requires that whatever is actually charged for the solar permit not exceed the Town's actual cost of issuing it. Call the Building Inspector (928-428-2290) or use the iWorq portal's live application flow for the current fee. |
Electric Vehicle (EV) Charging Station Permit
The Town of Thatcher has no distinct EV charger / EVSE permit type, application, or published fee. An EV charging station installation (new circuit, subpanel, or dedicated 240V branch circuit for a Level 2 charger) is permitted as standard electrical work under the Town's 2014 NEC adoption (Code of Ordinances Sec. 150.03), applied for through the same combined iWorq Citizen Portal 'Solar, Electrical, Gas or Plumbing permit' application used for all trade permits. Per Code of Ordinances Sec. 150.98, permit fees are set by Town Council resolution rather than published as a fixed schedule in the code text — the same fee gap already documented for Thatcher's general electrical-permit entry in this dataset. Re-chased for this review (2026-07-20): re-checked the Town's Document Center, Finance Department page, Agendas/Meeting archive, and the amlegal.com code library directly for a standalone fee-schedule resolution; no numeric electrical/building permit fee table was located in any of these locations, and no Wayback-archived version of a Thatcher fee schedule was found either.
