Unincorporated Lincoln County is not a city zoning counter

Lincoln County says it has no county planning and zoning in unincorporated areas, but floodplain, septic, fire-district, and city rules can still matter.

Outside Troy, Moscow Mills, and Elsberry, Lincoln County does not have the same planning counter a city project might have. The county has no dedicated Planning and Zoning Department and no planning and zoning within unincorporated areas. County permits also are not required for items such as occupancy permits and building permits.

That answer is narrow. Fire districts can be the lane for occupancy permits and electric codes. The Lincoln County Health Department handles septic codes and permitting. Floodplain development goes to the floodplain office. A project inside city limits belongs with that city or town’s planning and zoning department.

For land outside a city, the address still needs sorting. Unincorporated county, city, floodplain, septic, fire district, and private subdivision rules are different doors.
