Change of Use Permit in Evanston, Wyoming

Evanston does not maintain a separate stand-alone 'change of use' application or fee. Under City Code (Chapter 24, Zoning — Enforcement, Violations and Penalties), a building permit is valid only 'so long as the use of the building, structure or land remains the same as at the time of issuance'; a change of use therefore requires the property owner to obtain a NEW building permit through the standard Building Department process, charged under the same valuation-based fee schedule as any other building permit. A Certificate of Occupancy is issued at final inspection once the new-use permit's work and use are approved.

When you need this permit

  • A building permit becomes void when the use of the building, structure, or land changes from what was in effect at issuance — a new building permit application is required for the new use, per City Code Chapter 24 (Zoning), Enforcement, Violations and Penalties
  • Apply through the same iworq portal (portal.iworq.net/EVANSTON) and process used for the underlying building-permit type that matches the new use (e.g., commercial-tenant-improvement-permit for a commercial space use change)
  • Buildings changing occupancy type are one of the explicit Wyoming State Fire Marshal plan-review triggers under W.S. § 35-9-108 — confirm whether your change of use requires State plan review in addition to the City permit
  • A final Certificate of Occupancy is issued by the City once inspections for the new use are approved; builders remain responsible for correcting substantial subsidence occurring within one year of the Certificate of Occupancy's issuance or City acceptance, per the City's Technical Requirements

Tips

  • Evanston does not sell a distinct 'change of use permit' product — budget for a full new building permit under the fee/process of whatever permit type matches your new use.
  • If your change of use also changes occupancy classification, check W.S. § 35-9-108 — occupancy-type changes are an explicit state plan-review trigger, separate from and in addition to the City's own review.
  • Keep your final Certificate of Occupancy — the City can hold the builder responsible for correcting substantial subsidence discovered within one year of its issuance.

No. City Code (Chapter 24, Zoning) provides that a building permit is valid only so long as the use stays the same as at issuance, so a change of use requires a new building permit through the standard process rather than a distinct change-of-use product. The standard valuation-based building permit fee applies.

It can. Buildings changing occupancy type are one of the listed triggers for mandatory Wyoming State Fire Marshal plan review under W.S. § 35-9-108, in addition to the City's own building permit review — see the commercial-tenant-improvement-permit type for the full trigger list.
