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. Show full textShow less

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.
See fee scheduleResidential 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.
See fee scheduleElectrical 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.
See fee schedulePlumbing 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.
See fee scheduleMechanical / 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.
See fee scheduleAccessory 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.
See fee scheduleFence / 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.
$0Portable 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.
See fee scheduleResidential/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 record, 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 the last verification. Arizona statute A.R.S. § 9-468 independently caps whatever fee is actually charged at the Town's actual cost of issuing the permit.
See fee scheduleElectric 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 documented for Thatcher's general electrical-permit entry. No numeric electrical/building permit fee table appears in the Town's Document Center, on the Finance Department page, in the Agendas/Meeting archive, or in the amlegal.com code library, and no archived version of a Thatcher fee schedule exists either.
See fee scheduleCommercial Building Permit (New Construction / Tenant Improvement)
Required for new commercial construction and for remodels/tenant improvements of existing commercial space within Thatcher town limits. Thatcher administers commercial building permitting itself through its own Community Development/Engineering Department (Building Inspector, vested as Building Official under Code of Ordinances § 150.15) — it does NOT route commercial building safety or plan review to Graham County or a third-party contractor. There is no separate commercial application: the Town's iWorq Citizen Portal offers exactly five application categories, and its single 'Building, Addition, Remodel, Outbuilding, and Pool Permit Application' is described by the Town as covering 'a residential or commercial building, addition, remodel, outbuilding, or pool permit.' New commercial work is reviewed under the 2015 IBC as amended by the Town; alterations/tenant improvements to existing buildings fall under the 2015 International Existing Building Code, adopted with no local amendments (§ 150.08).

Tips & gotchas
- Arizona has no statewide mandatory building code — the Town of Thatcher independently recognizes and administers its own construction codes through the Community Development/Engineering Department (Building Inspector Mike Payne), without deferring to Graham County for permitting within town limits. Community Development/Engineering and Planning & Zoning share the same address, phone, and effectively the same office under the Town Manager.
- As of July 2026, Thatcher's own published materials show the 2015 ICC code family (IBC, IEBC, IRC, IMC, IFGC, IFC) plus the 2014 NEC still in effect, with the 2009 IECC, 2009 International Private Sewage Disposal Code, and 2009 International Urban-Wildland Interface Code explicitly RESCINDED outright ('no longer needed') rather than updated to a newer edition. No newer code-adoption ordinance was found published on the Town's website or Wayback Machine as of the last verification; confirm directly with the Building Inspector (928-428-2290) if code-cycle precision is critical to a specific project.
- Distinctive local amendments: residential automatic fire sprinklers are OPTIONAL ('may' not 'shall') per the Town's IRC amendment — unlike jurisdictions that mandate them; a 7,500 sq ft floor-area threshold triggers mandatory sprinklers for new/expanded structures generally; town-wide height cap of 45 ft (grade to highest point) or 30 ft (grade to top of highest outside wall); sewer depth flat 12-inch minimum regardless of freezing conditions; Arc-Fault Circuit-Interrupter Protection sections deleted from the IRC.
- Thatcher uses a single online iWorq Citizen Portal (thatcherpermitting.portal.iworq.net) covering essentially every permit type — residential/commercial building, addition/remodel/outbuilding/pool, infrastructure, sign, underground work, and solar/electrical/gas/plumbing — rather than a paper application or separate per-trade forms. A Site Plan Review Checklist (2 D-size copies) must accompany building plans.
- No fixed, published dollar-figure fee schedule exists anywhere in the Code of Ordinances or Zoning Ordinance — Code of Ordinances § 150.98 and Zoning Ordinance § 1.7 both state that all fees are set by separate Town Council resolution 'from time to time.' No such resolution document is published on the Town's website, Document Center, Forms Center, or in the Wayback Machine, and the historical Building Permit Application document (ID 962) now 404s with no archived snapshot available. Call the Building Inspector (928-428-2290) or use the iWorq portal's live application flow for current fee figures.
- Thatcher publishes no A.R.S. § 9-835-style plan-review-timeframe document: Chapter 150 is silent on the topic, and A.R.S. § 9-835 sets no statewide default — it only requires each municipality to publish its own. The one town-sourced turnaround figure comes from Thatcher Economic Development, an official Town of Thatcher program 'in the office of the Town Manager': 'Often, decisions can be secured within hours and many permits can be obtained in less than 10 working days from application.' That 0-10 working-day figure is applied uniformly across permit types in this record because the Town publishes no more granular, trade-specific timeframe anywhere — not in the Code of Ordinances, the Zoning Ordinance, the Document Center, or the Forms Center.
- Fences/walls (Zoning Ordinance § 13.9) and portable carports (§ 13.8.D) are the two NO-building-permit-required categories in Thatcher, per both the Zoning Ordinance text and the Town's own published flyers. Shops/sheds/accessory buildings DO require a permit and/or zoning clearance (§ 13.8.B.9).
- Accessory Dwelling Units were newly authorized town-wide by Ordinance No. 195-2024 (passed April 2024) — very recent. as of the last verification, no distinct ADU-specific fee or review-timeline document had been published separately from the standard Building Permit process.
- Swimming pool barriers in Thatcher are governed by Arizona's statewide pool-barrier statute, A.R.S. § 36-1681, rather than a Thatcher-specific ordinance; the state statute controls in a conflict. Nearby Safford handles pool barriers the same way. Design your barrier to the statute.
- Manufactured homes, mobile homes, and RVs are explicitly barred from use as an accessory building or ADU anywhere in Thatcher (Zoning Ordinance § 13.8.B.11 and § 13.8.A.2) — a hard rule with no case-by-case exception noted.
- Graham County's other PermitBase jurisdiction, Safford, uses a single unified PAPER Building Permit Application (rev. 06/17/2021) for all trades and publishes its own valuation-based fee table and a 'two to four weeks' review statement directly on that application — a materially different, MORE itemized model than Thatcher's online-only iWorq portal with no published fee table and no dedicated review-timeframe document.
