Codes, exemptions & field inspections
This guide translates the available agency record into a preconstruction checklist for structural scope, minor work, and inspection release. The adopted code and the issuing official control when a field condition is disputed.
Regulatory framework
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.
Inspection lane
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.
Minor-work playbook
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.
Field rule
A permit exemption generally addresses one narrow construction trigger. It does not automatically waive zoning, land-use, floodplain, shoreline, fire, energy, electrical, utility, septic, or right-of-way requirements. Obtain written confirmation when the project involves a new structure, structural alteration, change in occupancy, or concealed work.
Inspection pipeline
Request with lead time
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.
Preserve access
Do not cover framing, reinforcement, wiring, piping, damp-proofing, or life-safety work until the required inspection has been completed and documented.
Close the record
Retain the approved plans, inspection approvals, correction responses, and final certificate or occupancy release with the property file.
Contractor verification
Use the state licensing system to verify active registration, trade credentials, bond status, and liability coverage where available. Match the legal business name to the proposal and permit application.
Planning reference
A building permit is only one part of statutory compliance. Check the local zoning, ordinance, map, or land-use reference before finalizing setbacks, height, lot coverage, access, drainage, or accessory structure placement.

Field sequencing matters
Code compliance is not only a plan-review exercise. Footings, reinforcement, framing, fireblocking, wiring, piping, insulation, weather protection, and life-safety systems each have points where the work must remain accessible. Build the inspection calendar into the trade schedule instead of treating it as a final administrative step.
When a project qualifies for a narrow minor-work exemption, keep a written explanation of why it qualifies and confirm that related zoning, utility, fire, energy, or environmental rules do not create a separate approval requirement.
Closeout file
Keep the approved plan set, inspection approvals, correction responses, contractor license verification, final certificate, and any occupancy release together. A clean record protects the owner, builder, lender, insurer, and future buyer.
