Coverage · Eastern Idaho
Two things change between these towns, and both of them change the building: who issues the permit, and what ground snow load applies. A drawing set that cleared review in one town is not automatically valid in the next one over.
2015 University of Idaho study values. The number your permit is judged against is the one your jurisdiction has adopted — inside the City of Idaho Falls that is 47 psf.
Jefferson County issues the permit, not the city — and Rigby carries 32 psf against Idaho Falls' 23.
35 psf at 4,629 feet: higher load than Idaho Falls from lower ground. The city runs its own building department.
Bingham County seat, potato country, and two separate permit paths depending on which side of the city line you sit.
Fastest-growing city in Bonneville County at +13.5%, with its own building department and a 24 psf load.
Small cities where the jurisdiction question is not obvious — and where electrical permits changed hands in January 2026.
Work also happens in Idaho Falls itself and in the smaller communities between these towns. If your parcel is not listed, the two questions are the same: which office has jurisdiction, and what load applies there.
The design load and the reviewing office. Both follow the parcel, not the town on your mail, and both come back from a single address.
