Idaho · Off-grid & homestead potential
Gem County scores 69/100 on the Bolthole Index, a strong county profile. Its strengths are a stronger property-autonomy legal backdrop and sparse surroundings — about 64 people within a 30-minute drive. The trade-offs: more administrative friction around building and land use.
