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.
Fee desk contact
615-444-3025 (Building Codes); 615-604-5053 (Chief Building Official); 615-210-7850 or 615-504-2098 (inspectors)
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.

Project questions
Wilson County Building Codes Department / Zoning Division 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 615-444-3025 (Building Codes); 615-604-5053 (Chief Building Official); 615-210-7850 or 615-504-2098 (inspectors).
Inspection response target is within 72 business hours; no fixed plan-review turnaround was published. Residential permits expire under the county's zoning rules after 24 months without a certificate of occupancy or other final approval unless relief is granted.
Call Wilson County at 615-444-3025 to schedule all inspections. Inspectors generally have 72 business hours to conduct an inspection and do not perform same-day inspections. Typical stages include setback, slab plumbing, foundation, block/basement wall, framing/plumbing/mechanical rough-in, insulation, and final inspection before certificate of occupancy. The county's inspection list identifies Chris Richardson at 615-604-5053, Dan Broadrick at 615-210-7850, and Michael Cooper at 615-504-2098.
Wilson County's official Building Codes Division enforces the 2021 International Residential Code with adopted appendices, 2018 International Energy Conservation Code with state-approved amendments, 2021 International Building, Plumbing, Mechanical, Fuel Gas, Existing Building, and Swimming Pool and Spa Codes. For residential work, the county lists new construction, additions, major-load or major-use remodels, pools, and accessory structures as permit-regulated. A building permit is not needed for residential accessory structures under 200 square feet, but a zoning permit is required. For commercial accessory structures, the building-permit threshold is under 120 square feet. The zoning division separately lists $100 zoning permits for qualifying detached accessory structures up to 200 square feet and certain small decks; confirm project-specific requirements.
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.
