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.
Frequently asked questions
- Does the City of Evanston handle fire and electrical review for commercial buildings?
- 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.
