Project questions
Frequently asked questions for Clay 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 618-665-3346 and request the current application route before preparing a final submittal.
How long might review take?
A typical review timeline was not verified. Ask the agency for its current completeness and review estimate.
How are inspections scheduled?
N/A for ordinary building inspections. Contact the applicable municipality; the county Highway Department's published permits concern utilities, culverts, entrances, and highway rights-of-way.
Which codes and exemptions should I review?
N/A for a countywide building code. The county Highway Department publishes a Clay County Building Setback Ordinance and Utility Setback Ordinance, but no current building-code edition or general building-permit authority was identified. N/A countywide. The reviewed official county materials do not publish a building-permit exemption list; consult the applicable city or village before starting work.
