A Nashville property may need fire watch security when a required fire protection feature, such as the fire alarm, sprinkler system, fire pump, or another life-safety system, is impaired, offline, or insufficient for the current conditions at the building. The authority having jurisdiction (AHJ), which in Nashville and Davidson County is typically the Nashville Fire Marshal’s Office, determines whether fire watch is required, how long it must continue, and what the guard must document during each shift.
That is the short answer. The longer answer depends on what went wrong, what kind of property you manage, and which fire code official has authority over your building. This article walks through the most common fire watch scenarios Nashville property managers face, explains what the guard actually does on post, and covers the steps you should take the moment a life-safety system goes down.

A Nashville property may need fire watch when fire protection is reduced
Fire watch is not regular security. It is a specific response to a specific problem: something that normally protects the building from fire is not working, and someone needs to fill that gap until repairs are complete and the system is cleared to go back into service.
Under the fire codes that apply in Nashville, including the 2018 NFPA 1 Fire Code adopted through Metro Code of Ordinances Chapter 10.64, certain system outages require a trained person to patrol the affected areas on a documented schedule. The NFPA 25 standard for water-based fire protection systems, for example, addresses what must happen when a sprinkler system is out of service for more than ten cumulative hours in a 24-hour period. NFPA 101 (Life Safety Code) sets a four-hour threshold for fire alarm system impairments. But the Nashville Fire Marshal’s Office can order fire watch sooner than either threshold if the building type, occupancy, or scope of the outage warrants earlier action.
The key phrase here is authority having jurisdiction, often shortened to AHJ. The AHJ is the fire code official, typically the Nashville Fire Marshal’s Office for properties in Davidson County, who decides whether your building needs fire watch, how frequently the guard must patrol, what areas must be covered, and when coverage can end. Two buildings on the same street can have different requirements depending on their construction type, occupancy classification, and the nature of the impairment.
Properties in Brentwood, Franklin, Murfreesboro, Hendersonville, or other communities outside Metro Nashville may fall under a different AHJ with different adopted code editions. Always confirm which fire code official has authority over your specific property before assuming Nashville’s rules apply.
What fire watch security means
A fire watch guard is a trained person assigned to patrol a building or area where fire protection has been reduced. The guard watches for smoke, fire, blocked exits, unsafe conditions, combustible material buildup, and other visible hazards. The guard maintains a written fire watch log that records times, areas checked, observations, any actions taken, and required contacts.
The guard knows how to start the emergency notification process: calling 911, alerting property leadership, contacting the monitoring company, and reaching the responsible parties listed in the post orders. The guard also helps maintain clear access and egress within the assigned post.
What the guard does not do is equally important. A fire watch guard does not repair alarms, sprinklers, fire pumps, or suppression systems. The guard is not a fire-system technician, a firefighter, or a code inspector. The guard does not decide when fire watch can end. That call belongs to the AHJ.
Patrol intervals vary. The AHJ or the approved fire watch plan sets the route, frequency, staffing level, and documentation requirements for each property. Do not assume a single patrol interval applies to every building.
Common situations that can trigger fire watch
Fire alarm system outages
When a fire alarm panel goes offline, malfunctions, loses communication with monitoring, or gets intentionally shut down for repair, the building may lose its primary detection and notification system. Under NFPA 101, fire watch may be required when a fire alarm system has been impaired for more than four cumulative hours in a 24-hour period. Nashville’s fire marshal can direct coverage sooner, especially in occupied buildings with high tenant counts or public assembly areas.
Common causes include panel failures after power surges, false alarm lockouts, wiring damage during renovation, and scheduled maintenance that runs longer than planned. An apartment community in Antioch with 200 units and a dead alarm panel is a very different risk than a small office suite with ten employees and a working smoke detection system in every room.
Sprinkler or suppression system impairments
Sprinkler shutdowns, broken mains, frozen pipes, valve closures, fire pump failures, and impaired kitchen suppression systems all fall under this category. NFPA 25, Section 15.5.2, addresses what happens when a water-based system is out of service for more than ten cumulative hours in a 24-hour period: the building must either be evacuated or an approved fire watch must be established.
“Cumulative” is the word that catches property managers off guard. A system that goes down for six hours in the morning, comes back briefly, and then goes down again for five hours that afternoon has exceeded the threshold. The Nashville Fire Marshal’s Office may also order fire watch before the ten-hour mark depending on the building’s occupancy type, construction class, or the scope of the impairment.
Construction, renovation, and planned shutdowns
Active construction work regularly creates fire watch situations. Hot work, including welding, cutting, grinding, torch-applied roofing, and soldering, requires its own fire watch under NFPA 1. But the need goes beyond hot work. Temporary walls, dust barriers, blocked sprinkler heads, disconnected alarm zones, removed exit signs, altered egress paths, and system modifications during a build can all reduce fire protection enough to trigger fire watch.
Nashville’s construction market generates a steady volume of these situations. A contractor renovating a floor of an office building in the Gulch may need fire watch for the duration of a sprinkler zone shutdown. A developer building a new mixed-use project in Germantown may need it during system tie-in work that takes the existing detection offline for several days.
Special events and temporary high-risk conditions
Large events, performances, exhibits, and temporary high-occupancy situations can create conditions that exceed the building’s normal fire protection design. A tent with capacity for 300 or more people on Lower Broadway may require fire watch under Nashville Fire Department event permit conditions. An indoor event that blocks exits, overloads electrical circuits, introduces pyrotechnics, or brings in combustible decorations can trigger the same requirement.
The Nashville Fire Marshal’s Office reviews event permit applications and may require fire watch as a condition of approval. This applies to venues and outdoor events throughout Davidson County.
Fire, storm, or property damage
After a fire, severe storm, flooding, electrical failure, or physical impact damages the building’s fire protection systems, exits, structural fire barriers, or alarm infrastructure, fire watch may be needed until repairs are complete and the system has been inspected and returned to service.
Nashville properties face these situations after tornado warnings, severe thunderstorms, and the occasional ice storm that knocks out power and damages alarm panels. A warehouse near the Airport corridor with storm damage to its sprinkler riser is not optional to leave unmonitored while waiting for the contractor.
Which Nashville properties most often need coverage
Fire watch comes up across nearly every commercial property type in Middle Tennessee. Some categories see it more often than others.
Apartment and multifamily communities in Antioch, Madison, Brentwood, Franklin, and Hendersonville deal with alarm panel failures, sprinkler impairments from unit renovations, and water damage to fire protection systems. A property manager overseeing 300 units with a dead panel at 10 PM does not have the luxury of waiting until Monday morning to figure out next steps.
Hotels, entertainment venues, restaurants, and event spaces along Downtown Nashville, Midtown, Music Row, and the Gulch face fire watch situations tied to system maintenance, kitchen suppression work, event permits, and renovation projects in occupied buildings.
Warehouses, distribution centers, and manufacturing properties near the Airport corridor, MetroCenter, Murfreesboro, and La Vergne often need fire watch during sprinkler modifications, racking changes that affect sprinkler clearance, and after storm or equipment damage.
Office buildings, mixed-use developments, healthcare facilities, retail centers, churches, schools, and active construction sites throughout Nashville and Davidson County also account for a significant share of fire watch requests.
If your alarm or sprinkler contractor has confirmed an outage and the AHJ has directed fire watch, our team can review the post details and coverage request. Visit the fire watch services page or reach out through our contact page for more information.
What a fire watch guard does during each shift
The guard follows the patrol route, frequency, post orders, and documentation requirements established for the property. This is not a desk assignment. The guard walks the affected areas on a set schedule, looking for smoke, fire, unsafe work, blocked exits, combustible material buildup, and other visible hazards within the assigned scope.
Every patrol is logged. The fire watch log records the time of each round, the areas checked, observations, any actions taken, and contacts made. If the AHJ or insurer requests copies of the log, the property manager should be able to produce them immediately.
If the guard finds a hazard or detects smoke or fire, the guard initiates the emergency notification process. That means calling 911, contacting property leadership, reaching the monitoring company, and alerting any other responsible parties listed in the post orders.
The guard also helps keep access and egress paths clear within the assigned post. If a stairwell door is propped open, an exit is blocked by deliveries, or a fire lane is obstructed, the guard documents it and takes the corrective action outlined in their orders.
One thing the guard does not do: determine the patrol interval. The AHJ or approved fire watch plan controls how often patrols occur. Some properties require rounds every 15 minutes. Others allow 30 or 60 minutes. The interval depends on the building, the impairment, the occupancy, and the AHJ’s judgment. Do not assume a standard applies across the board.
Who decides how long fire watch must continue
The AHJ decides. In Nashville and Davidson County, that is usually the Nashville Fire Marshal’s Office. In surrounding communities, it may be the local fire department, a county fire marshal, or the state fire marshal’s office.
Fire watch continues until the impaired system has been repaired, inspected, tested, and returned to full service. The AHJ, not the security company, determines when the building can be released from fire watch. The property manager should get written confirmation or documented approval before ending coverage.
In practice, a minor alarm panel repair might be resolved within a few hours. A major sprinkler riser replacement after storm damage could take days. A construction project that shuts down fire protection in phases might need rolling fire watch coverage for weeks. The cost and duration depend entirely on how long the system stays impaired and how quickly the responsible contractor can complete the repair.
What property managers should do when a system goes down
Step 1: Confirm the impairment. Identify exactly which system or life-safety feature is affected. Get the specifics from your alarm company, sprinkler contractor, or building engineer. Note the time the impairment started.
Step 2: Call the responsible contractor. Contact the alarm, sprinkler, suppression, electrical, or other repair contractor. Get an estimated timeline for repair.
Step 3: Notify the AHJ. Contact the Nashville Fire Marshal’s Office (for properties in Davidson County) or the correct local or state fire code official for your property. Ask what interim measures are required, including patrol frequency, logs, staffing, notifications, occupancy restrictions, and permits.
Step 4: Arrange qualified fire watch coverage. If the AHJ directs fire watch, or if the impairment timeline makes it likely, arrange coverage with a provider that understands fire watch documentation, patrol requirements, and AHJ reporting.
Step 5: Brief the guard. Provide site maps, keys, emergency contacts, known hazards, access instructions, and approved post orders. The guard needs to know the building before starting the first patrol.
Step 6: Maintain logs and records. Keep fire watch logs organized and accessible. The AHJ, your insurer, or property ownership may request them at any point.
Step 7: Document repair completion. When the system is repaired, get it inspected and tested. Obtain written confirmation from the AHJ or the responsible inspector that the system has been returned to service. Do not end fire watch coverage until that confirmation is in hand.

Frequently asked questions
When is fire watch required in Nashville?
Fire watch may be required when a fire alarm, sprinkler system, fire pump, suppression system, or another life-safety feature is impaired, offline, or insufficient. The Nashville Fire Marshal’s Office or other applicable AHJ determines whether fire watch is needed based on the type of impairment, the building’s occupancy, and the adopted fire code. NFPA 101 references a four-hour threshold for fire alarm impairments, and NFPA 25 addresses a ten-hour threshold for water-based systems, but the AHJ can order coverage sooner.
Does a broken fire alarm require fire watch?
It can. Under NFPA 101, fire watch may be required when a fire alarm system has been impaired for more than four cumulative hours in a 24-hour period. The Nashville Fire Marshal’s Office may direct fire watch earlier depending on the building type and occupancy. Contact the AHJ for your property to confirm.
Does a sprinkler system shutdown require fire watch?
In many cases, yes. Under NFPA 25, Section 15.5.2, if a water-based fire protection system is out of service for more than ten cumulative hours in a 24-hour period, the building must be evacuated or an approved fire watch must be established. The Nashville Fire Marshal’s Office may require it sooner.
Who can perform fire watch at a commercial property?
Fire watch must be performed by trained personnel whose sole duty during the assignment is patrolling the affected areas and documenting observations. A fire watch guard is not a regular lobby officer or door monitor reassigned to walk the building. The person must be trained in fire hazard recognition, extinguisher use, emergency notification, and fire watch documentation.
What does a fire watch guard document?
The guard maintains a fire watch log that records the time of each patrol round, the areas inspected, any observations or hazards noted, actions taken, and contacts made. The AHJ or the approved fire watch plan may specify the exact log format, patrol interval, and reporting requirements.
How long does fire watch have to remain in place?
Fire watch continues until the impaired system has been repaired, tested, inspected, and returned to full service, and the AHJ has released the property from coverage. A minor panel repair might take hours. A major sprinkler replacement after storm damage could take days.
Can a Nashville building stay occupied during fire watch?
In many cases, yes, provided that fire watch is in place and any additional conditions set by the AHJ are met. However, the AHJ can also restrict occupancy, limit operations, or order partial or full evacuation depending on the severity of the impairment. The decision belongs to the fire code official, not the property manager or the security company.
