Fire Protection System (Sprinkler/Alarm/Suppression) Plan Review in Unincorporated Fremont County, Wyoming

Fremont County itself issues NO fire-protection-system permit — consistent with the rest of this file, the county has no county-wide building code and no county fire-code enforcement authority. Per the county's own Building Codes & Certificates of Occupancy page (re-verified live 2026-07-22), 'Installation, addition, or alteration of fire protection systems (i.e. fire alarm, fire sprinkler, fire suppression)' requires plan review by the Wyoming State Fire Marshal's Office (Dept. of Fire Prevention & Electrical Safety) 'regardless of size or valuation' — the same statewide authority (grounded in W.S. § 35-9-108) already documented in this file's codesAdopted section and its electrical/solar/EV-charger permitType entries. The Fremont County Fire Protection District (Riverton, (307) 857-3030) is confirmed (via its own live site, checked 2026-07-22) to be a volunteer suppression/response agency only — it does not itself perform plan review, issue permits, or charge fees; that is the WSFM's role statewide. Fetched directly from wsfm.wyo.gov/fire-prevention/plan-review (live 2026-07-22): submittals go through the WSFM eLicensing/ePermit/ePayment portal, are accepted or rejected within 5 business days, and complete submittals are reviewed within 21 business days of acceptance (or 10 business days after any requested resubmittal, whichever is longer). Fetched directly from wsfm.wyo.gov/fire-prevention (live 2026-07-22): 'Upon completion and the passing of all inspections a Certificate of Occupancy or Letter of Compliance is issued' — by the State, notwithstanding Fremont County's own explicit non-issuance of Certificates of Occupancy.

  • Fremont County has no county-level fire-protection-system permit, fee, or review process of its own — this is administered entirely by the State

  • Plans are accepted or rejected for review within 5 business days of receipt

  • No work may begin before a Permit to Construct is issued
  • Fees are calculated per the Department of Fire Prevention & Electrical Safety Rules (Chapter 2, Section 3 fee schedule); the applicant is notified of the amount due when plans are accepted, payable before the Permit to Construct issues — no flat published dollar figure was found during this chase (see fees notes)

Fee schedule

Fire Protection System Plan Review FeeWyoming State Fire Marshal's Office states fees are calculated per the Department of Fire Prevention & Electrical Safety Rules, Chapter 2, Section 3 fee schedule, and the applicant is notified of the exact amount due when plans are accepted; fee is payable before a Permit to Construct is issued. A specific numeric fee schedule document was searched for directly (wyoleg.gov interim-committee filing) but the retrieved PDF was an unreadable scanned image with no extractable fee text — chase exhausted without inventing a number. Contact the WSFM Plan Review office (Jeff Schoen, (307) 673-1461, jeff.schoen@wyo.gov) for the current fee.

Tips

  • Fremont County Fire Protection District (Riverton, (307) 857-3030) is the local volunteer fire-suppression/response agency — confirmed via its own live site that it does not perform plan review or charge permit fees. All fire-protection-system plan review and permitting for unincorporated Fremont County goes through the Wyoming State Fire Marshal's Office in Cheyenne, not the local district.
  • This same WSFM plan-review requirement applies 'regardless of size or valuation' — unlike ordinary building alterations, which only trigger state plan review at a $40,000+ valuation threshold per the county's own Building Codes page.
  • No fee dollar figure is published online; budget for an unknown amount and expect WSFM to disclose it only after plans are accepted — contact WSFM Plan Review directly for a current estimate before budgeting a project.
