Project questions
Frequently asked questions for Marshall County
Who handles permitting for this jurisdiction?
Marshall County Zoning Department 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?
No verified online portal was located in the reviewed public materials. Contact 309-246-6401 (Highway and Zoning); 309-246-3446 and request the current application route before preparing a final submittal.
How long might review take?
The permit application requires construction to begin within 6 months of issuance and completion within 18 months; review turnaround is N/A.
How are inspections scheduled?
For commercial buildings, the owner or agent must contract with a qualified inspector and file the inspection certification with the county before occupancy; the county will not issue a commercial zoning-compliance certificate without it. Contact the Zoning Department at 309-246-6401.
Which codes and exemptions should I review?
Marshall County is a non-building-code jurisdiction. Commercial construction must comply with Illinois requirements for qualified inspection and certification; the county commercial guidance references the 2006-or-later International Building, Existing Building, and Property Maintenance Codes and the 2008-or-later National Electrical Code. The applicant is responsible for code compliance before occupancy. Agricultural-use building permits have no charge, although the application requires written notification and setbacks. Towers up to 35 feet do not require a permit. Other buildings, additions, and land uses generally require a county building permit; confirm project-specific exemptions with the Zoning Administrator.
