Wellton, Arizona has adopted: 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 Wellton operates its own Building Safety Division within its Department of Community Development and independently adopts and administers its own construction codes; it does not defer building permitting to Yuma County. Source: Town of Wellton Building Permits page (welltonaz.gov/1226/Building-Permits).; 2009 International Codes (I-Codes), as published by the International Code Council — the Town of Wellton's own live Building Permits page states verbatim: 'The Town of Wellton is currently following the 2009 International Council Code (ICC).' This is independently corroborated by the 2025 AZBO (Arizona Building Officials) Directory, which lists the Town of Wellton's 'Adopted Codes' as '2009 I Codes' with no separate electrical-code edition listed. Unlike most other AZBO-directory Arizona jurisdictions (which have since moved to 2015, 2018, or 2024-cycle I-Codes and separate NEC editions), Wellton's own published information has not been updated past the 2009 cycle as of this review — this reflects the Town's genuinely small size (approx. 2,600-3,000 population) and correspondingly thin published code-update cadence, not a research gap. Source: Town of Wellton Building Permits page (welltonaz.gov/1226/Building-Permits, live page text); 2025 AZBO Directory (azbo.us), Town of Wellton entry, p. 21.; The 2009 International Building Code (IBC), International Residential Code (IRC), International Mechanical Code (IMC), International Plumbing Code (IPC), International Fuel Gas Code (IFGC), International Fire Code (IFC), and International Existing Building Code (IEBC) are understood to be adopted as a single 2009 'I-Codes' package per the Town's own code-adoption statement; the Town's Building Permit Application form lists six permit-type categories that align with this code family: Building, Plumbing, Mechanical, Electrical, Fire Sprinkler, and Demolition.

Source: Town of Wellton Mobile Home Placement page (welltonaz.gov/1225/Mobile-Home-Placement) and Mobile Home Placement Permit Application (PDF, DocumentCenter Doc ID 313).; No dedicated, separately-published Town of Wellton fee schedule, master fee resolution, or ICC valuation table was found on the Town's official website, DocumentCenter, or in its adopted annual budget documents (FY2024-2025, FY2025-2026) as of this review. The Town's own Building Permit Application form leaves 'Valuation' and 'Permit Fees' as blank fields completed by Building Safety Division staff at intake, consistent with fees being calculated per-project from the adopted 2009 I-Codes' own valuation-based fee tables rather than a separately republished municipal fee schedule. This is a genuine gap in the Town's public documentation (typical for a town this size) rather than an omission in this research — confirmed by direct review of the Town's Finance Department, Development Services, and Development Impact Fees pages, none of which publish an itemized building-permit fee table.
