Tips

  • Confirm early whether your commercial project triggers mandatory Wyoming State Fire Marshal plan review (W.S. § 35-9-108) — this is a SEPARATE review and fee from the City's, and approved State copies must be provided to the City before construction begins.
  • Sign permits, grading/stormwater permits, and impact fees are billed separately from the base building permit fee.

Evanston, Wyoming has adopted: 2024 International Building Code (IBC) — current edition per City of Evanston Building Permit Legal Requirements; 2024 International Residential Code (IRC) — residential construction incorporates current IRC requirements per Evanston City Code § 7-52.1; 2021 Uniform Plumbing Code (UPC) provision cited for irrigation backflow prevention (UPC 608.17.5); confirm current adopted plumbing code edition with the Building Department; Evanston local design load values (wind, seismic, snow, frost depth) apply IN ADDITION TO the International codes — see localAmendments; IMPORTANT: Electrical work in Evanston is NOT governed by a City-adopted electrical code — electrical permitting and inspection is performed by the Wyoming State Fire Marshal's Office (Chief Electrical Inspector) under the state's default statewide electrical program (W.S. § 35-9-119), per the WSFM 'LOCAL AND STATE JURISDICTIONS' chart (Evanston = ELEC INSP/PR: S/S) and confirmed directly by the City's own Building Inspection Information sheet ('Electrical: Contact State of Wyoming Electrical Inspector'); IMPORTANT: Building PLAN REVIEW in Evanston has a state-law overlay — per W.S. § 35-9-108, the Wyoming State Fire Marshal must review and approve plans (in addition to city review) for: buildings/structures owned or leased by state/local government; buildings for general public access exceeding 5,000 sq ft total floor area; buildings over one story (incl. apartments/condos); childcare centers for more than 10 children; public bars/lounges/restaurants/night clubs/lodge halls/theatres/churches/public meeting places regardless of size; aboveground fuel dispensing facilities; alternate energy generation feeding the utility (incl. solar); Type I commercial kitchen exhaust hoods; spray finish applications; and buildings changing occupancy type — this matches the WSFM jurisdictions chart classification of Evanston building plan review as having a State component (STATE BLDG INSP/PR designation) alongside the City's own local building permit issuance and inspection program. Local amendments apply — see the Evanston overview page for the full list.

Not entirely. The City's own guidance states that state reviews are sent directly to, and fees paid directly to, the State of Wyoming for qualifying buildings, and the Evanston Fire Department conducts a separate review/approval from any State Fire Marshal review.
