Clarke County Engineer's Office / Zoning Administrator is the identified county-level authority for this profile. Confirm that the property is in its service area before filing.
How should I begin an application?
Begin with the online permit gateway listed in the application guide. If the portal does not recognize the address or project type, contact 641-342-2716.
How long might review take?
N/A; the county does not publish a standard application-review timeline. A zoning certificate becomes void if construction, alteration, or change of use has not started within six months, and proposed work must be completed within 18 months.
How are inspections scheduled?
Submit the current fillable zoning permit application with scaled site and building plans showing lot dimensions, structure location, size, height, use, and related information; the site and proposed building must be staked before construction. Contact the Zoning Administrator through the Engineer's Office at 641-342-2716 for review and inspection arrangements. No separate online inspection-booking portal was published.
Which codes and exemptions should I review?
Clarke County Zoning Ordinance No. 42, effective September 17, 2025, including A-1 Agricultural, R-1 Rural Residential, R-2 Manufactured Home Community, P-1 Planned Development, C-1 General Commercial, I-1 Industrial, FP Floodplain Overlay, and AP Airport Overlay districts; building permits, zoning compliance, setbacks, lot coverage, height, use controls, subdivision, and floodplain requirements apply in unincorporated areas. Applicable Iowa state technical building, electrical, plumbing, mechanical, environmental-health, and floodplain requirements also apply. A specific 2026 county technical building-code edition was not identified. Agricultural uses may receive a zoning exemption under Iowa Code and the county's zoning guidance; the current ordinance expressly exempts agricultural uses from filing plot plans. No broad minor/cosmetic exemption list was published. Properties inside Osceola, Murray, or Woodburn must use the applicable city requirements rather than the county process.
