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
DeKalb County adopted the State of Tennessee Building Codes in January 2011. The state residential program uses the 2018 International Residential Code and 2018 International Energy Conservation Code; electrical permits and inspections are conducted by the State of Tennessee.
Inspection lane
Footing, framing, rough-in, and final inspections may be required; do not conceal work before inspection. County fees include plan review, required inspections, and up to three re-inspections. Contact the Building Department at 615-215-2633 or 931-256-1524 to arrange inspections; electrical inspections are scheduled through Tennessee.
Minor-work playbook
Detached garages, sheds, barns, decks, and pole barns that are not occupied or conditioned do not require a permit. Agricultural buildings used solely for farm purposes may be exempt. Insulated, heated, cooled, or occupied structures require a permit; confirm applicability with the Building Department.
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
Footing, framing, rough-in, and final inspections may be required; do not conceal work before inspection. County fees include plan review, required inspections, and up to three re-inspections. Contact the Building Department at 615-215-2633 or 931-256-1524 to arrange inspections; electrical inspections are scheduled through Tennessee.
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.
