Zoning/Construction Permit (Land Use) — not a building-code permit in Unincorporated Sweetwater County, Wyoming
VerifiedSweetwater County does not issue a code-enforcement building permit for private construction. Instead, the county's Land Use Department requires an approved ZONING permit before any residential, commercial, industrial, or mineral construction/use begins in the unincorporated county — most projects use the 'Construction' application (which also covers oil & gas well permitting). This is a land-use/zoning approval, not an IBC/IRC building-code plan review or inspection program.

When you need this permit
- Confirm zoning district and any Growth Management Plan overlay requirements (Rock Springs/Green River growth-area) before applying
- Submit the 'Construction' application form (covers residential and non-residential construction, including oil & gas wells) available from the Land Use Office
- Submit an Address application if establishing a new address is also needed
- Apply BEFORE construction begins — the county assesses a Late Application Fee for construction started without an approved permit application
- Contact the Land Use Office (307-872-3914 or 922-5430) if unsure which application applies to your project

Inspection process
Tips
- There is NO county building-code permit (no IBC/IRC plan review or inspection program) in unincorporated Sweetwater County — confirm this before assuming code-based inspections apply.
- The zoning/construction permit is a land-use approval, not a life-safety code inspection; it does not substitute for the state electrical wiring permit or the county septic/access approvals below.
- A Late Application Fee applies if construction starts before the zoning/construction application is approved.
Frequently asked questions
- Do I need a county building permit to build a house in unincorporated Sweetwater County?
- No. Sweetwater County has not adopted a countywide building code or taken building-code enforcement authority under W.S. 35-9-121, so there is no county building permit with IBC/IRC plan review. You DO need the county's zoning 'Construction' permit from the Land Use Department before starting construction, plus any applicable state electrical permit, septic permit, and driveway/access permit (see below).
