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.

Project questions
Smith County Planning Office / Land Use Regulations Administrator 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 615-735-3418.
N/A; no general review timeline was published in the accessible official materials.
Submit the permit application to the Smith County Planning Office. The official planning page identifies the office as responsible for building permits, electrical permits, and inspections outside the three city limits. The application requires project, parcel, zoning, floodplain, septic, and 911-address information; call 615-735-3418 for inspection arrangements. State residential inspections may be requested through https://core.tn.gov when the state program applies.
The county application states that Tennessee has adopted the International Building Codes and requires a properly licensed contractor under T.C.A. 62-6-103. For one- and two-family residential work in jurisdictions using the state program, Tennessee identifies the 2018 International Residential Code and 2018 International Energy Conservation Code; confirm the code edition and any municipal requirements for the specific project. Smith County's zoning resolution states that it does not require building permits for agricultural buildings or other non-residential structures on land devoted to agricultural use, subject to the stated statutory limitations. Tennessee guidance also indicates that installation of a manufactured or modular home itself may not require a state residential permit, although custom site work such as a deck, patio, or stoop may require one. The county's development guide states that new construction and decking on mobile homes require a state building permit; verify the exact exemption with the Planning Office before starting work.
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.
