Codes, exemptions & field inspections

Build to the adopted code. Verify every exception.

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 code baseline for Lewis County.

Lewis County states that it has no building-and-codes department and requires no county building permit for any size or type of residential or commercial structure outside Hohenwald. County residents still must comply with Tennessee septic-system and electrical-safety requirements. Within Hohenwald, the municipal fallback's codified adoptions are the 2012 International Building, Residential, Plumbing, Fuel Gas, Mechanical, Energy Conservation, Existing Building, and Property Maintenance Codes, with local amendments; applicants should confirm whether later administrative amendments apply before relying on an edition.

Inspection lane

Unincorporated Lewis County publishes no county building-inspection program because it requires no county building permit. For projects inside Hohenwald, call the Building & Codes Department at 931-796-2231 or the Building Official at 931-628-2768 to schedule required footing, foundation/framing, plumbing, mechanical/gas, energy, and final inspections; the city publishes separate inspection checklists on its Building & Codes page.

Minor-work playbook

Understand what may be exempt—and what is not.

All structures in unincorporated Lewis County are exempt from a county building permit, and the county specifically says no permit is required for an emergency backup generator; state septic and electrical requirements still apply. Within Hohenwald, locally retained permit exemptions include fences not over 7 feet; painting, papering, tiling, carpeting, cabinets, countertops, and similar finish work; prefabricated pools under 24 inches deep; swings and playground equipment; qualifying wall-supported window awnings; and certain shade-cloth or nonfixed display fixtures. The city deleted other standard model-code exemptions, so verify the project with the Building Official.

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.

Contractor verification

Verify the builder before the contract is signed.

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

Keep the parcel rules beside the building plans.

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.

Which codes and exemptions should I review?

Field sequencing matters

The inspector needs to see the work at the right moment.

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.
