Tombstone, 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 (A.R.S. Title 9). The City of Tombstone is a home-rule city that independently adopts and administers its own construction codes through its own Building Department; it does not defer building permitting to Cochise County despite its small size (2020 Census population 1,307). Source: Tombstone City Code, Title 3 (Building Regulations), Chapter 1 (Building Code), codelibrary.amlegal.com/codes/tombstoneaz (current through Ord. 2025-06, passed 10-14-2025).; 2006 International Residential Code (IRC) and 2006 International Building Code (IBC), adopted by reference as 'the Uniform Building Code' of the City, per Tombstone City Code Section 3-1-1 (Adoption of Building Codes). NOTE: this is a genuinely old code cycle (2006, not a current ICC edition), corroborated by two independent sources: (1) the codified City Code text itself (codelibrary.amlegal.com/codes/tombstoneaz/latest/tombstone_az/0-0-0-1834), and (2) the Arizona Building Officials (AZBO) statewide directories, whose most recent editions (2018/2021) list Tombstone's adopted codes as 2006 IBC/IRC/IMC/IPC and 2005 NEC. The current Building Permit Application (Rev. 1/2024) also cites 'Tombstone City Code, 3-1-1: Adoption of the Uniform Building Code' and references 'Uniform Building Code Permit Requirements' by name, consistent with the 2006-cycle adoption never having been updated to a current ICC edition.

This is a very old NEC edition (1988) relative to current AZ municipal practice (most Cochise County peers are on 2017 or 2020 NEC) — confirmed via direct code-section fetch; no more recent NEC adoption ordinance was located despite a search for 'building code' + ordinance amendments through the current Ord. 2025-06 code-currency marker.

No IFGC (fuel gas), IFC (fire) or IEBC (existing building) adoption is located in Title 3, and Title 6 "Fire Regulations" contains exactly one section (6-1-1) defining the geographic fire limits under the 1972 Code.
