- A permit application is deemed abandoned 180 days after filing unless pursued in good faith or issued (IRC/IBC Section 105.3.2 amendment).
- Electrical (Fire Department) inspections cannot be scheduled through the online portal even though they may appear as an option — contact Jackson Hole Fire/EMS directly.

Frequently asked questions

- Who handles electrical permits for a home in unincorporated Teton County?
- The Electrical Division of the Jackson Hole Fire/EMS Department — a jointly-funded Town of Jackson / Teton County fire district — not the Wyoming State Fire Marshal's statewide program and not the County Building Division directly.
