Fire Protection System (Fire Alarm / Fire Sprinkler) Plan Review — State Program in Unincorporated Sweetwater County, Wyoming
Sweetwater County has not taken delegated fire-code plan-review authority under Wyoming Statute 35-9-121 — the Wyoming State Fire Marshal's (WSFM) 'Local and State Jurisdictions' chart lists the county's Fire PR (Plan Review) column as State (S), consistent with this file's already-verified reading of that same chart for Building and Electrical (chart updated 7/7/2026, re-verified 2026-07-16; https://wsfm.wyo.gov/electrical-safety). Installation, addition, or alteration of a fire protection system — fire alarm, fire sprinkler, or fire suppression — requires a Plan Review submitted to the WSFM Dept. of Fire Prevention & Electrical Safety, regardless of project size or valuation, before work may begin (W.S. 35-9-108(j); WSFM Plan Review program, https://wsfm.wyo.gov/fire-prevention/plan-review). This is a state-administered plan review/permit, separate from the county's zoning/construction permit and from the state Electrical Wiring Permit.

When you need this permit
- Plan Review is required for installation, addition, or alteration of any fire protection system (fire alarm, fire sprinkler, fire suppression), regardless of size or valuation, before work begins (WSFM Plan Review program; W.S. 35-9-108(j))
- Submit complete plans and specifications through the Wyoming State Fire Marshal's eLicensing, ePermit, and ePayment Portal
- Plans shall be accepted or rejected for review within 5 business days of receipt; a complete, accepted submittal is reviewed within 21 business days of acceptance (an additional 10 business days if the department requests more information, or the original 21 days, whichever is greater)
- Fire alarm and fire sprinkler plans are submitted as successive-phase plans after the initial building/electrical plan review is approved (W.S. 35-9-108(s))
- For remodeling costing under $40,000 that affects a built-in fire protection system, the plan-review fee is capped at $50/hour (W.S. 35-9-108(q)(ii)); larger projects and new construction are billed per the department's valuation-based fee schedule (Rules Ch. 2 §3), using the ICC Building Valuation Data table and a locally-calculated Permit Fee Multiplier — not a flat dollar figure
- After completion, WSFM inspects the system/building and, if compliant, issues a Certificate of Occupancy for newly constructed buildings or a Letter of Compliance for remodeled buildings before the space may be used or occupied (W.S. 35-9-108(n)); the underlying plan-review trigger in W.S. 35-9-108(a) applies mainly to public buildings, multistory public buildings, childcare centers over 10 children, and public bars/restaurants/theaters/churches/meeting places, not routine single-family construction

Tips
- This is a STATE plan review/permit (WY Dept. of Fire Prevention & Electrical Safety), separate from and in addition to the state Electrical Wiring Permit and the county's zoning/construction permit — a project with new fire-suppression or alarm work can require three separate approvals.
- The WSFM jurisdiction chart lists Sweetwater County's Fire Plan Review as State (S) but Fire Inspection as Local (L) — unlike Electrical and Building, which are S/S. That means field-inspection responsibility may sit with a local fire authority even though WSFM handles plan review; this file does not resolve which specific local fire department covers a given unincorporated-county location.
- WSFM's own Personnel & Inspectors page lists Travis Mayer as the WSFM regional Fire Inspector whose assignment includes the Sweetwater County communities of Bairoil, Granger, Green River, Superior, and Wamsutter (Rock Springs, an incorporated city with its own fire department, is not on that list) — confirm which authority applies to your specific unincorporated-county location before assuming WSFM performs the field inspection.
- There is no flat-dollar fire sprinkler/alarm permit fee published for larger projects — the fee is calculated via a valuation-based formula and disclosed only after WSFM accepts the plans; only the sub-$40,000 remodel case has a stated cap ($50/hour).
