Project questions
Frequently asked questions for Decatur County
Who handles permitting for this jurisdiction?
This record is marked Municipal Fallback. Confirm whether a city, state agency, or other local authority controls the parcel before filing.
How should I begin an application?
No verified online portal was located in the reviewed public materials. Contact 641-446-3665 and request the current application route before preparing a final submittal.
How long might review take?
N/A for building permits; the county publishes no county building-permit review timeline. Municipal timelines vary. County environmental-health and right-of-way permit timing was not stated in the reviewed materials.
How are inspections scheduled?
For septic and wastewater permitting or inspections, contact Decatur County Environmental Health Sanitarian Jessica Bear at 641-446-3665 or 641-572-0665. For construction inside a municipality, arrange building inspections with that municipality. For county-road entrances or right-of-way work, contact the County Engineer; non-permitted entrances may be removed or corrected by county forces at the applicant's expense.
Which codes and exemptions should I review?
Decatur County's official 2026 board materials state that the county currently has no zoning and was only discussing whether to form a county zoning committee. No county building-code ordinance or building-permit office was identified. Building permits and inspections must be confirmed with the municipality having jurisdiction; applicable Iowa State Building Code requirements and local municipal codes apply. The county does enforce environmental-health requirements, including Iowa and county rules for on-site wastewater systems and private wells, and the County Engineer controls county right-of-way permits. No county building-permit exemption list was published because no county building-permit program was identified. Municipalities may have their own exemptions for minor, cosmetic, agricultural, or accessory work; confirm directly with the applicable city or town. A county septic permit is required before construction of or addition to a dwelling or building served by an on-site wastewater system.
