Tips

  • This is a zoning/land-use permit, not a structural building-code permit, unless the parcel falls within the mapped 'Sheridan County Building Standards Area' near the City of Sheridan — see codesAdopted notes.
  • The application form itself directs applicants to three separate state-level permits that may also apply: WSFM electrical permit (new electrical work), State Engineer's Office water-well permit (new wells), and WYDOT access permit (driveways onto state highways).
  • A copy of an approved access permit (WYDOT or county driveway permit) must be submitted WITH the zoning permit application, not after.

Unincorporated Sheridan County, Wyoming has adopted: NO countywide building code / NO general building permit for private construction in unincorporated Sheridan County. Per the Wyoming State Fire Marshal's 'Local and State Jurisdictions' chart, Sheridan County (county-level row) is listed BLDG INSP/PR = STATE and ELEC INSP/PR = STATE — the county has NOT taken general countywide building-code delegation under W.S. § 35-9-121, so the State Fire Marshal / state program has building and electrical jurisdiction across most of unincorporated Sheridan County.; IMPORTANT NUANCE (confirmed on the county's own site): Sheridan County DOES have an adopted 'Building Standards, Sheridan County, Wyoming' rule (adopted Nov. 18, 1991; last amended May 16, 2023, filed as County Clerk doc. #2023-785780) that adopts the 2021 International Building Code, 2021 IRC, 2021 IMC, 2021 IFGC, 2021 IPC, 2021 International Fire Code, the 2022 National Electrical Code, and the Uniform Code for the Abatement of Dangerous Buildings — but ARTICLE I, Section 3 (Applicability) confirms this code applies ONLY within a mapped 'Sheridan County Building Standards Area' (a defined zone around/adjoining the City of Sheridan shown on the Appendix A Planning Map), PLUS specific legacy subdivisions the BOCC imposed permitting/inspection on before Dec. 5, 2006, all NEW subdivisions approved after Dec. 5, 2006, and any structure built under a Conditional Use Permit. It does NOT apply countywide.; Farms and ranches on 40 acres or more of deeded land are specifically EXEMPT from the Building Standards code entirely (Article I, Sec. 3(b)(1)), as are county hospitals, mines/oilfield/refinery facilities, and railway buildings.; Where the Building Standards DO apply (the mapped area / qualifying subdivisions / CUP structures): a building permit is required before construction of any building/structure valued over $5,000 (Article III, Sec. 1), enforced by the Sheridan County Building Official.; Where the Building Standards do NOT apply (the vast majority of unincorporated Sheridan County — rural and agricultural land outside the mapped area): there is no county building permit for private construction; a Zoning Permit (land-use/setback compliance, not a structural building-code permit) is still required countywide for new construction or change of use.; Electrical: wiring permits/inspections are issued by the Wyoming State Fire Marshal's Office — Dept. of Fire Prevention & Electrical Safety (Chief Electrical Inspector), not Sheridan County, per the county's own Zoning Permit application which directs applicants doing new electrical work to WSFM..
