Process

How the permit process works

Confirm whether a permit is required Use the 2018 IRC and Tennessee residential code exemption thresholds as the first screen: attached decks always require a permit; freestanding decks above 30 inches or over 200 square feet also require one. If the deck is near any threshold, confirm with Metro Nashville Codes Administration before starting work.
Check zoning setbacks and overlay districts Metro Nashville zoning rules set minimum setbacks from property lines, easements, and other structures. If the property is in a historic, urban design, or other special overlay district, identify the additional review requirements before drawing plans.
Prepare plans and structural documents Draw up a scaled site plan and construction drawings covering footing depths and sizes, post and beam sizing, joist spacing, decking layout, ledger attachment detail if attached, and guardrail and stair details. Metro Nashville reviews to the 2018 IRC with Tennessee amendments.
Submit through the Metro Nashville permit portal Log in to the Metro Nashville permit portal, select the residential building permit type, upload the application and supporting plans, and submit. In-person service is available at Metro Nashville Codes Administration, 800 Second Avenue South, Nashville, TN 37210.
Respond to plan review comments Codes Administration reviewers check the submittal against the 2018 IRC, Tennessee state amendments, and Metro Nashville zoning. If corrections are requested, revise the drawings and resubmit through the portal.
Receive permit, pay remaining fees, and post on site After approval, pay any outstanding fees and keep the permit and approved drawings accessible at the job site throughout construction as required by Tennessee law.
Schedule and pass required inspections Request inspections through the permit portal as construction progresses. A typical Nashville deck requires a footing inspection before pouring concrete, a framing inspection before covering any structural members, and a final inspection on completion.
Pass final inspection and close the permit After final approval, the completed deck is part of the official Metro Nashville building record, protecting you at resale, for insurance claims, and on future permit applications.

You may be required to expose finished work or remove deck sections so inspectors can verify structural compliance — at the owner's expense.
Civil penalties can accrue daily until the violation is resolved under Metro Nashville ordinance.
Historic overlay violations create a separate compliance problem on top of the unpermitted construction issue.
Insurance claims involving unpermitted structural work can be complicated or denied.
Future buyers, lenders, and title companies may flag unpermitted work and require retroactive permitting or corrective work before closing.
