Codes adopted

Arizona has no statewide building code for non-state buildings; codes are adopted locally. According to the International Code Council, codes are adopted locally in Arizona and are predominantly the I-codes, with different cities and counties choosing their own editions and local amendments. The Arizona State Fire Code (adopting the 2018 IFC) applies only to state and county buildings, public and private schools, and non-residential occupancies in areas without a locally adopted fire code — it does not establish a statewide residential or commercial building code floor. Each city and county adopts its own code editions independently, resulting in different I-Code years and amendment sets across jurisdictions. There is no state-mandated minimum edition; enforcement is entirely local. Always confirm the adopted edition and any local amendments with the specific jurisdiction before submitting plans.

• Arizona has NO statewide mandatory building code floor for general construction — code adoption is a per-city/county authority under state enabling statutes (e.g., A.R.S. Title 9 for municipalities). The Town of Thatcher independently recognizes and administers its own construction codes through the Community Development/Engineering Department (Building Inspector), under Chapter 150 of the Town of Thatcher Code of Ordinances.

Permit types & fees

• Residential Building Permit (New Construction)

  Required for new single-family dwelling construction within Thatcher town limits. Reviewed against the 2015 IRC and 2015 IBC (for any non-residential portions) as adopted and amended by the Town of Thatcher. Applications are submitted online via the Town's iWorq Citizen Portal, with plans and a Site Plan Review Checklist uploaded as PDFs.

  →

• Residential Addition / Remodel Permit

  Required for room additions, remodels, and outbuildings to existing one- and two-family dwellings in Thatcher, generally allowed but may require a building permit. Reviewed against the 2015 IRC and Zoning Ordinance Section 13.8 (Accessory Buildings and Uses) as amended by the Town.

  →

• Electrical Permit

  Required for electrical installation, alteration, or repair work in Thatcher, governed by the 2014 National Electrical Code as adopted by the Town with no local amendments noted. Applications submitted via the same iWorq Citizen Portal used for solar, gas, and plumbing permits.

  →

• Plumbing Permit

  Required for plumbing installation, alteration, or repair work in Thatcher, governed by the 2015 International Plumbing Code as adopted and amended by the Town, including a Town-specific sewer-depth amendment.

  →

• Mechanical / HVAC Permit

  Required for heating, ventilation, and air conditioning installations in Thatcher, governed by the 2015 International Mechanical Code as adopted and amended by the Town.

  →

• Accessory Dwelling Unit (ADU) Permit

  Newly authorized town-wide by Ordinance No. 195-2024 (passed April 2024), allowing attached and/or detached accessory dwelling units on single-family residential lots in Thatcher, subject to size, setback, height, and foundation requirements under Zoning Ordinance Section 13.8.A.

  →

• Fence / Wall Permit (Zoning Clearance, No Building Permit Required)

  Fences and walls in Thatcher are governed entirely by Zoning Ordinance Section 13.9 and do NOT require a building permit town-wide, though the Town strongly recommends a Planning & Zoning materials/location check before construction.

  →

• Portable Carport Zoning Clearance (No Building Permit Required)

  Portable carports in Thatcher require Site Plan Review but explicitly do NOT require a building permit under the adopted IBC, per Zoning Ordinance Section 13.8.D.

  →

• Residential/Commercial Solar Photovoltaic (PV) Permit

  Required 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.

  →

• 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.
