Lincoln County (county seat: Kemmerer) covers 4,095 square miles with a population of 19,581 (2020). Official county website: www.lincolncountywy.gov/government/planning_development/documents_forms.php. This page summarizes the verified building-regulation posture of unincorporated Lincoln County land; the full 10-dimension scorecard with every source receipt lives on its Freedom Map card.
NOT a no-code county. Lincoln County Planning & Development requires a Building Permit Application (new residential 1 & 2 family dwellings and additions, plus auxiliary buildings) and a Zoning & Development Permit, and enforces multi-chapter Land Use Regulations with zoning, overlays and setback/easement standards. Its residential design criteria are published as 'Recommended Residential Design Criteria' (IRC-based) rather than a hard-adopted, county-inspected structural code — so a building permit + zoning is mandatory but full structural inspection appears advisory. Scored 6: clearly more regulated than a permit-only county, less than a full building-department 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 Lincoln County and how hard.
The score describes unincorporated county land only. Inside Lincoln County, incorporated municipalities set their own, usually stricter, rules — including: Kemmerer, Afton, Alpine, Thayne, Star Valley Ranch, Diamondville, Cokeville, LaBarge, Opal. Land inside town limits follows town code.
Building rules are the first question people ask about Lincoln 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.
