Beaver County (county seat: Beaver) covers 2,592 square miles with a population of 7,072 (2020). Official county website: www.beaver.utah.gov. This page summarizes the verified building-regulation posture of unincorporated Beaver County land; the full 10-dimension scorecard with every source receipt lives on its Freedom Map card.
Statewide Utah State Construction Code (2021 IBC/IRC) applies AND Beaver County runs a full building department. Permit required for any structure over 200 sq ft even without electricity; separate electrical/mechanical/plumbing/gas permits required (each $75.75). Trade permits are triggered even in accessory structures under 200 sq ft if electrical is added. Ag-use non-dwelling structures may qualify for the state 15A-1-204 exemption. Moderate — clearly not a no-code county.
The claim above is source-verified (official statute/county documents; URL, direct quote, and date on the full card). Method: how we verify.
No county's freedom erases state law: septic/wastewater permitting (health authority), well permits and water rights (state engineer/DNR), floodplain rules with federally connected financing, and — in some states — state-run electrical inspections. The full card details which of these bite in Beaver County and how hard.
The score describes unincorporated county land only. Inside Beaver County, incorporated municipalities set their own, usually stricter, rules — including: Beaver, Milford, Minersville. Land inside town limits follows town code.
Building rules are the first question people ask about Beaver County — and the easiest one to answer. They're rarely the one that decides it. The full card grades all ten dimensions, every claim quoted from the county's own code.
