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
Effective January 1, 2024: 2018 IRC for residential construction; 2018 IBC, IFC, IPC, IMC, IFGC, IECC and NFPA 101 for commercial construction, with county amendments. The county’s adopted resolution retains selected 2009 IECC/IRC energy provisions and excludes residential electrical chapters; electrical permits/inspections are state-administered.
Inspection lane
The permit holder must coordinate and schedule inspections in the required order through the iWorQ portal, by email at codes@cumberlandcountytn.gov, or by phone at 931-710-5727. Required stages include footing, slab, foundation, rough-ins, energy and final; a Certificate of Occupancy is required before occupancy. No inspection is scheduled without a permit. A $100 reinspection fee applies after two failed inspections per job site.
Minor-work playbook
Agricultural buildings are exempt from permits. Accessory buildings, garages and decks that are not part of new residential construction are also exempt under the county’s adopted building-code resolution. Confirm scope-specific exemptions with Codes 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
The permit holder must coordinate and schedule inspections in the required order through the iWorQ portal, by email at codes@cumberlandcountytn.gov, or by phone at 931-710-5727. Required stages include footing, slab, foundation, rough-ins, energy and final; a Certificate of Occupancy is required before occupancy. No inspection is scheduled without a permit. A $100 reinspection fee applies after two failed inspections per job site.
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.
Open planning reference ↗Source trail
Use these direct agency or licensing links to confirm current instructions before you file, pay, or schedule work. External pages control if their information differs from this directory.
Project questions
This record is marked Municipal Fallback. Confirm whether a city, state agency, or other local authority controls the parcel 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 931-710-5727.
Mechanical, HVAC, gas-line and plumbing applications are stated to be reviewed within 2-3 business days. No separate building-plan review timeline was published.

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.
