Fees, valuation & enforcement
Permit fees are a project input. Enforcement exposure is a project risk. Use the official schedule where available, then confirm valuation, trade permits, plan review, and inspection charges with the Authority Having Jurisdiction.
Official fee pathway
The final charge may depend on declared construction value, occupancy classification, square footage, plan review, state surcharges, trade permits, technology fees, and inspection activity. Do not use a neighboring city’s fee table as a substitute for this jurisdiction.

Ask the counter to confirm current charges before submitting a project with multiple trades or a change of use.
Financial exposure
Plan for building, mechanical, plumbing, electrical, fire, energy, zoning, septic, right-of-way, or other reviews that the project scope triggers. The lowest initial permit fee is not always the lowest project cost.
Enforcement exposure
When work begins without authorization, the agency may halt the site, require corrective plans, impose additional fees, withhold inspection release, or require concealed work to be exposed for review.
Closeout exposure
A missing final inspection or certificate can complicate occupancy, refinancing, sale, insurance, and utility connection. Preserve the approved plans and signed inspection record through closeout.
Professional field note
Even when a cosmetic or minor project does not require a building permit, zoning, floodplain, shoreline, historic, utility, fire, or right-of-way controls may still apply. Confirm the full jurisdictional picture before work starts.

N/A; Metro states each reviewing department has its own processing timeframe and publishes no standard overall review timeline.
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.
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. 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.
Why permit costs vary
Building departments commonly calculate charges from valuation, occupancy, floor area, project type, plan review effort, trade scope, state surcharges, and inspection activity. A remodel that appears small on paper may still trigger structural, energy, fire, or utility review. Ask the permit counter which disciplines apply before you finalize the construction budget.
The same discipline applies to enforcement. Correcting unpermitted work after finishes are installed can require demolition, revised plans, additional inspections, and schedule disruption. Authorization is usually the less expensive project-management decision.
