Fees, valuation & enforcement
Permit fees are a project input. Enforcement exposure is a project risk. Use the official schedule where available, then confirm valuation, trade permits, plan review, and inspection charges with the Authority Having Jurisdiction.
Official fee pathway
The final charge may depend on declared construction value, occupancy classification, square footage, plan review, state surcharges, trade permits, technology fees, and inspection activity. Do not use a neighboring city’s fee table as a substitute for this jurisdiction.

Ask the counter to confirm current charges before submitting a project with multiple trades or a change of use.
Financial exposure
Plan for building, mechanical, plumbing, electrical, fire, energy, zoning, septic, right-of-way, or other reviews that the project scope triggers. The lowest initial permit fee is not always the lowest project cost.
Enforcement exposure
When work begins without authorization, the agency may halt the site, require corrective plans, impose additional fees, withhold inspection release, or require concealed work to be exposed for review.
Closeout exposure
A missing final inspection or certificate can complicate occupancy, refinancing, sale, insurance, and utility connection. Preserve the approved plans and signed inspection record through closeout.
Professional field note
Even when a cosmetic or minor project does not require a building permit, zoning, floodplain, shoreline, historic, utility, fire, or right-of-way controls may still apply. Confirm the full jurisdictional picture before work starts.

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.
Why permit costs vary
Building departments commonly calculate charges from valuation, occupancy, floor area, project type, plan review effort, trade scope, state surcharges, and inspection activity. A remodel that appears small on paper may still trigger structural, energy, fire, or utility review. Ask the permit counter which disciplines apply before you finalize the construction budget.
The same discipline applies to enforcement. Correcting unpermitted work after finishes are installed can require demolition, revised plans, additional inspections, and schedule disruption. Authorization is usually the less expensive project-management decision.
