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
2024 International Building Code, International Residential Code, Existing Building Code, Fuel/Gas Code, Mechanical Code, Plumbing Code, Swimming Pool and Spa Code, and Energy Conservation Code; 2023 National Electrical Code; 2017 ICC A117.1, all with Metro amendments.
Inspection lane
Registered contractors schedule inspections through ePermits; homeowners should coordinate through Metro Codes/Building Division. Building inspection 615-862-6550; electrical 615-862-6560; plumbing and gas/mechanical 615-862-6570. An inspection checklist is issued with the permit, separate trade inspections are required, and a final Use and Occupancy Letter follows completed inspections.
Minor-work playbook
Normal maintenance repairs generally do not require a building permit, including painting, papering, window/door glazing, floor finishing, minor chimney/stair/porch/underpinning repairs, and roof repairs up to 33% of roof area. Fences generally do not require permits. Accessory structures 100 sq ft or more require permits; verify project-specific rules with Metro Codes.
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
Registered contractors schedule inspections through ePermits; homeowners should coordinate through Metro Codes/Building Division. Building inspection 615-862-6550; electrical 615-862-6560; plumbing and gas/mechanical 615-862-6570. An inspection checklist is issued with the permit, separate trade inspections are required, and a final Use and Occupancy Letter follows completed inspections.
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.

Project questions
Metropolitan Government of Nashville and Davidson County Department of Codes and Building Safety is the identified county-level authority for this profile. Confirm that the property is in its service area before filing.

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.
