Unincorporated Albany County, Wyoming has adopted: Albany County has NOT adopted a countywide building code and does NOT issue a general IBC/IRC-style building permit for private construction in unincorporated areas. Under Wyoming's local-option delegation statute (W.S. § 35-9-121), county-level building-code enforcement authority is opt-in via application to the State Fire Marshal; Albany County has not taken that authority, so the State Fire Marshal's Office retains BOTH building and electrical jurisdiction countywide (WSFM 'Local and State Jurisdictions' chart, header reads 'UPDATED 7/7/2026' — corrected 2026-07-17 from a stale '5/11/2026' citation, embedded at https://wsfm.wyo.gov/electrical-safety, lists Albany County BLDG INSP/PR = S and ELEC INSP/PR = S, re-confirmed unchanged 2026-07-17).; The county's OWN site confirms this: Albany County Planning's permit menu and Land Use Permit Fee Schedule (https://www.albanycountywy.gov/253/Planning ; fee schedule PDF https://www.albanycountywy.gov/DocumentCenter/View/6249/Fee-Schedule) contain NO International Building Code / International Residential Code adoption and NO 'building permit' fee line — only zoning, floodplain, wastewater, subdivision, sign, tower, and wind/solar fees. The county's own application labels its zoning approval for new residential/commercial structures 'Zoning Certificate & Rural Address (Building Permit)' — i.e., the county's stand-in for a building permit is a ZONING review against the Albany County Zoning Resolution, not a state building-code plan review/inspection.; The Albany County Zoning Certificate application (https://www.albanycountywy.gov/DocumentCenter/View/4521/Zoning-Certificate-Application) confirms review is 'by the Planning Department' for compliance with 'the Albany County Zoning Resolution' — land-use/setback/use compliance, not IBC/IRC structural or life-safety code compliance.; Practical takeaway: if you are building in unincorporated Albany County, you generally do NOT need a county building permit for the construction itself, but you DO need the county's Zoning Certificate (a land-use/placement approval, sometimes informally called the 'building permit' by the county) plus any of the real exceptions below that apply to your project (floodplain, septic/small wastewater, driveway access, state electrical)..
