Research notes

Significant carve-out in a state where the majority of unincorporated land is rural/agricultural. Combined with the §18-5-301 35-acre subdivision exemption, large swaths of WY's unincorporated land effectively fall outside county zoning oversight. Residential agricultural buildings (farmhouses, ranch dwellings) remain subject to county zoning; the exemption is for production-use agricultural structures.
