NASHVILLE GUIDE

Permits and repairs after water damage in Nashville

Drying a wet room and putting the room back are different kinds of work, and only some of that work raises a permit question. This page is not Metro's rulebook. It is a list of what to ask, and where to ask it, before someone closes a wall.

This page is not the permit office

Metro Nashville's Department of Codes and Building Safety is the public office for building and trade permits inside the consolidated city-county. Rules, forms, and which jobs need a review change, and they depend on the address and the scope. Anything printed here as a yes-or-no permit answer would be a guess, and a guess is how a project gets stuck. Use the department's own pages, or ask them about the address, before you rely on a contractor's shrug. If the house is not actually in Metro's jurisdiction, ask the city or county that issues permits for that lot instead of assuming Nashville's office is the one.

We do not list fees, and we do not recite a cutoff in dollars or in square feet. Those details are exactly the kind of thing that goes stale or that has exceptions. Your job is to get the answer for this repair, in writing if the scope is large, from the office that can say no.

Drying is not the same job as rebuilding

Extracting water, setting air movers, and pulling out finishes that stayed wet is restoration work. It often happens in the first days, sometimes before anyone has talked about a permit, because wet drywall does not improve by waiting through a humid Nashville week. Public-health guidance on mold is measured in days once materials stay damp. That urgency does not convert tear-out into a finished renovation, and it does not mean every later step is permit-free.

The moment the work turns into putting plumbing back, moving or adding electrical circuits, changing structure, or rebuilding walls and floors, you are in a different conversation. A drying crew can be done and gone while the permit question is still open. A quote that says "dry and rebuild" in one line is hiding that seam. Ask which part is which. The cost guide is about why those parts should not share one vague number.

Plumbing, electrical, and structure

A split supply line, a water heater that dumped into a finished room, or a drain that has to be opened is plumbing work. Tennessee licenses plumbers and other contractors through the state Board for Licensing Contractors. This site is not that board and does not decide who needs which license. Ask who will pull the plumbing permit if one is required, and ask for the license the company claims. You can check a license with the state board instead of trusting a logo on a shirt.

Electrical work after a flood in a wall, a wet panel, or new circuits for drying equipment that somehow became permanent wiring is the same kind of question for electricians. Do not let a drying invoice quietly include "we rewired the bath." If the panel was wet, the safety issue comes before the paperwork. Keep people away from it, and let a qualified person say whether it can be re-energized.

Structure is the piece homeowners under-ask. A soft floor next to a tub can be wet plywood, or it can be a joist that needs more than a new sheet of subfloor. A ceiling that sagged and was cut out may need more than fresh drywall if the reason it sagged was a heavy, long soak. Ask, before the new board goes up, whether anyone looked at the framing and whether that look is in writing. The hiring guide separates industry training such as IICRC courses from a government license. Both questions belong in this conversation. Training does not replace a permit, and a permit does not tell you the drying plan was any good.

Who pulls it, and whose name is on it

Ask who submits the permit: you, the general contractor, or the trade doing the work. Ask whose license number is on the application. A handshake that "we pull permits all the time" is not the same as a permit number you can look up. Metro's public permit tools exist so a property owner can see applications tied to an address. Use them if you were told a permit was issued. If the company says no permit is required, ask them to say that in the proposal, and then confirm with Codes if the work includes plumbing, electrical, or rebuilding. Their opinion and the office's answer should match before the wall is closed.

Insurance does not settle the permit question. A carrier can approve a repair estimate and still leave you responsible for doing the work in the way the local code office requires. The insurance notes are about documenting the loss, not about skipping inspections. Keep the two files separate: what the adjuster agreed to pay, and what the permit, if any, says must be inspected.

Before the drywall goes back up

Walk the repair before it disappears. You want moisture readings that say the cavity is dry, a note of what insulation was replaced, photos of any new plumbing or wiring while it is visible, and a clear statement of what was not done. If a roof opening caused the indoor damage, the roof repair and the indoor close-up should not race each other. Drying a ceiling while rain can still enter is how you buy the same job twice. Storm paths are described on the storm intrusion page.

Mold is the other reason not to rush the close-up. If materials stayed wet, the drying scope should say what was removed and what was monitored. Painting a stained cavity is not an inspection. The mold page on this site is the consumer version of that caution. Ask whether anyone is recommending a separate assessment, and do not confuse that suggestion with a permit.

Questions worth reading aloud before demolition starts, including who is licensed and what "dry" means, are gathered on the questions page. Permits are one item on that list, not a substitute for the rest. If you remember nothing else, remember the order: stop the water, dry what can be saved, then ask Codes and the state license board about the rebuild before the new finishes hide the work.
