Can a homeowner pull the permit?
Yes, in most cases. Owner-occupied primary residences. Requirements vary enormously — Teton County is strict; many rural counties have none.
Where to file: County or municipal building department where one exists. Cheyenne, Casper, Jackson have processes. Much of rural Wyoming has no permitting. Plan review 1-3 weeks where required.
