Digital permit application gateway
Start with the issuing authority’s own submission lane. A complete application package, accurate valuation, and accessible inspection path are the fastest route through statutory plan review.
Recommended first click
Use the official digital gateway to submit plans, monitor review comments, pay required charges, and request inspections when the permit is issued. If the link is unavailable, use the agency website or phone number on the administrative profile to confirm the current lane.
Typical review lane
N/A; the reviewed county materials do not publish a standard plan-review timeline. Permit applications can be abandoned after one year unless diligently pursued, with possible extensions.
Treat this as a planning signal, not a guaranteed approval date. Completeness, corrections, resubmittals, and agency workload control the actual clock.
Verify the parcel is inside this agency’s service area and note whether a city, state, fire marshal, septic authority, or utility district also has approval authority.
Prepare legible plans, site information, project valuation, ownership authorization, contractor information, and any energy, floodplain, zoning, or utility documentation the issuing office requires.
Keep the permit number, approved plan set, correction comments, fee receipts, and inspection results together. Those records establish the compliance trail for the next trade.
Application documents
Before submission, call 815-544-6176 if the project involves a change of occupancy, structural alteration, accessory structure, demolition, or work near a regulated environmental feature.
Source trail
Use these direct agency or licensing links to confirm current instructions before you file, pay, or schedule work. External pages control if their information differs from this directory.

Call 815-544-6176 for building and mechanical inspections. The application lists inspections when the footing is ready before concrete, after walls are coated and drain tile is installed before backfill, before insulation after rough electrical/plumbing approval, insulation, and final inspection before occupancy.

For unincorporated Boone County, the codified ordinance adopts the 2021 International Building Code with local amendments, 2021 International Residential Code, 2021 International Fuel Gas Code, 2020 National Electrical Code, Illinois Plumbing Code, and a limited 2003 International Property Maintenance Code provision; the county also enforces locally adopted zoning and state laws. The county's fuel-gas amendments exempt portable heating appliances, minor component replacements that do not change an appliance's approval or make it unsafe, portable ventilation appliances, portable cooling units, steam/hot-water/chilled-water piping within regulated equipment, portable evaporative coolers, and self-contained refrigeration packages. The general permit code's exemptions remain subject to all other laws and ordinances; deck/porch/pier construction in unincorporated Boone County requires a permit.
What makes an application complete
Before you click submit, make sure the drawings agree with the site plan, project description, valuation, ownership authorization, and contractor information. If the work changes structure, occupancy, drainage, fire protection, energy performance, or utility demand, describe that scope plainly. Ambiguous narratives create correction cycles and delay the field schedule.
Save the confirmation number, payment receipt, uploaded plan set, and every correction comment. Those records are the backbone of a defensible compliance file when multiple trades or agencies share responsibility.
Submission quality check
Site: address, parcel, access, setbacks, and existing conditions are consistent.
