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
No general permit-review timeline is published. Temporary and final Certificates of Occupancy are generally processed within three business days; inspections require at least 24 hours' notice.
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 573-886-4330 (Resource Management); 573-886-4339 (Inspections) 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.
Project questions
Boone County Resource Management — Planning, Inspection, and Engineering Services is the identified county-level authority for this profile. Confirm that the property is in its service area before filing.
Begin with the online permit gateway listed in the application guide. If the portal does not recognize the address or project type, contact 573-886-4330 (Resource Management); 573-886-4339 (Inspections).
No general permit-review timeline is published. Temporary and final Certificates of Occupancy are generally processed within three business days; inspections require at least 24 hours' notice.
Submit the online permit application with all required information and a site drawing; incomplete submissions are not processed. New construction requires a site/setback inspection before permit issuance effective June 1, 2026. After the application and payment are processed, call the Inspections office at 573-886-4339 to schedule; the county requires at least 24 hours' notice and does not schedule inspections by email. A Certificate of Occupancy is required before occupancy, and the county says temporary/final certificates generally take three business days to process.
2015 International Codes for Boone County, including the 2015 International Building, Residential, Mechanical, Plumbing, and related codes with Boone County addenda; the inspection page states these codes apply to permits issued on or after April 1, 2017. County jurisdiction is primarily the unincorporated area; Columbia has its own building office, while the county has agreements with Centralia, Sturgeon, Harrisburg, Hallsville, Hartsburg, and Rocheport. Cosmetic work does not require a building permit. The county does not require a demolition permit, although the Fire Protection District or Health Department may have separate requirements. The county's published permit list generally requires permits for commercial or industrial structures, single-story residential/accessory structures over 160 square feet, structural/electrical/plumbing/HVAC/insulation work, homes and additions, re-roofing, mobile/modular homes, garages, carports, sheds, barns, workshops, pools, greenhouses, fences over 12 feet, retaining walls over 4 feet, and towers.
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.
Scope: structural, mechanical, plumbing, electrical, fire, and energy work is identified.
Closeout: inspection contacts and the final approval path are understood before work begins.
