NASHVILLE CODE GUIDE
By the Ironsmith Fire Engineering Team · Nashville, La Vergne, Middle Tennessee
In Nashville and most of Davidson County, the Nashville Fire Department’s Fire Marshal’s Office reviews fire sprinkler plans and inspects new systems, working alongside Metro Codes. The Tennessee State Fire Marshal licenses the sprinkler contractor. Once the system is in, the building owner is responsible for inspection, testing and maintenance, and each fire sprinkler inspection in Nashville gets reported through an online system the fire department requires.
Quick facts
- Metro runs it, not the state. The State Fire Marshal lists Nashville and Davidson County as an exempt jurisdiction, so Metro handles plan review and inspections for most buildings.
- Plans go in through Codes. A design professional submits one complete electronic plan set to Metro Codes. The Fire Marshal’s Office reviews the fire and life safety side. Paper isn’t accepted.
- Yes, you need a permit. The Fire Marshal’s Office says a permit is required to install a sprinkler system.
- Three inspection points. Before walls and ceilings close, during system testing, and at completion.
- Nashville is on the 2024 codes. Metro adopted the 2024 International Fire Code and 2024 NFPA 101, with local amendments. The statewide fire code is still the 2021 IFC.
- The owner owns ITM. After opening day, inspection, testing and maintenance are the owner’s job.
- Reports go online. Nashville requires service providers to file reports through Inspection Reports Online, or IROL.
Fire sprinkler inspection in Nashville starts with who’s in charge
If you’re building, buying or managing a commercial property in Nashville, you’ll deal with three offices: Metro Codes, the Nashville Fire Marshal’s Office and the Tennessee State Fire Marshal. Each one signs off on something different.
Know which does what and your project moves. Guess wrong and you lose weeks to a rejected submittal or a failed inspection. Here’s how it fits together.
Metro or the state? Check this first
Tennessee’s State Fire Marshal’s Office lets certain local governments run their own plan review and inspections. It calls them exempt jurisdictions, and Nashville and Davidson County is one of them.
There are exceptions:
- Five satellite cities sit outside it. Belle Meade, Berry Hill, Forest Hills, Oak Hill and Ridgetop aren’t covered by Metro’s exemption.
- Some buildings stay with the state. The State Fire Marshal still reviews state-owned buildings, educational occupancies and some state-licensed facilities.
If your project falls in one of those buckets, confirm who reviews it before you submit anything.
Who signs off on what
| Step | Who handles it |
|---|---|
| Sprinkler contractor registration | Tennessee State Fire Marshal’s Office |
| Plan submittal | Metro Codes, electronic only |
| Fire and life safety plan review | Nashville Fire Marshal’s Office |
| Field inspections and acceptance testing | Nashville Fire Marshal’s Office |
| Final approval toward the Use and Occupancy letter | Nashville Fire Marshal’s Office |
| Ongoing inspection, testing and maintenance | The building owner |
| Filing ITM reports | Your service provider, through IROL |
Step 1: Hire a registered sprinkler contractor
In Tennessee, a sprinkler firm needs a Certificate of Registration as a Fire Protection Sprinkler System Contractor from the State Fire Marshal’s Office. Every registered firm has to employ a licensed Responsible Managing Employee, who qualifies through Tennessee engineering or architecture registration or NICET Level III certification.
Here’s the part owners miss. The state rule’s definition of sprinkler service covers inspecting and testing, not just installing and repairing. So the company that inspects your system needs that registration too. Ask for the certificate number. It’s printed on every service tag they hang.
Step 2: Submit plans through Metro Codes
All plan review in Nashville is electronic. A design professional submits one complete plan set to Metro Codes, and the Fire Marshal’s Office reviews it for fire and life safety. Metro doesn’t offer expedited review.
A few things that trip up projects:
- Deferred submittals. In most cases, sprinkler, fire alarm, emergency power and firefighter air replenishment drawings can come in after the building permit. Metro asks for them within 90 days of the construction permit being issued.
- Flow tests. Some projects need a two-hydrant flow test run by the water utility within the previous six months. Old flow data won’t cut it.
- Timing. Metro’s published average is 4 to 6 weeks for most commercial construction, additions, renovations and site plans. That’s a general figure, not a promise for sprinkler shop drawings.
Step 3: Pass the field inspections
The Fire Marshal’s Office inspects at three points: before walls and ceilings are covered, during system testing, and at completion. Final approval feeds the Use and Occupancy letter you need to open.
The Fire Marshal’s Office says the most common reason an inspection fails is simple. The stamped plans and the comment sheet aren’t on site. Keep both at the job, every visit.
Step 4: Keep it inspected for the life of the building
Once the building opens, Nashville puts ITM squarely on the owner. The Fire Marshal’s Office says owners, occupants, managers or their designees are responsible for making sure systems are properly inspected, tested and maintained. NFPA 25 sets the intervals. Our NFPA 25 inspection schedule builds yours in a couple of minutes, and our guide to ITM explains each piece.
How reports reach the fire marshal
Nashville requires service providers to file through Inspection Reports Online, a web-based reporting program. Report types include initial acceptance tests, annual sprinkler and fire pump inspections, five-year internal pipe inspections, five-year standpipe tests and annual private hydrant inspections.
Owners can register for free to see the reports filed on their buildings. Nashville’s AHJ number in the system is TNA11435. If you’ve never looked, it’s worth five minutes to confirm your reports are actually on file.
Which fire code applies in Nashville
Metro adopted the 2024 International Fire Code and the 2024 edition of NFPA 101, Life Safety Code, with local amendments, in Chapter 10.64 of the Metro Code. Metro also adopted the 2024 International Building Code for applications submitted after it took effect in July 2025.
That puts Nashville a cycle ahead of the state, which still enforces the 2021 IFC and IBC. If your designer usually works elsewhere in Tennessee, make sure they’re designing to Nashville’s editions.
