Fire watch in Texas,
done to code.
When Texas requires a fire watch, what the code actually says, the patrols and logs your fire marshal expects, how long the watch must run and what it costs — from operators who staff these posts across the state.
Systems down?
The clock is already running.
SECURICO staffs licensed fire watch posts across Texas with same-day deployment, digital round logs and post orders written to your fire marshal's instructions. This guide covers what those instructions will say.

A failed fire watch fails three ways at once.
Fire marshals treat impairment violations seriously: citations, daily fines and — for an occupied building running without protection or watch — a vacate order that empties your property mid-repair.
Carriers write protection-impairment requirements into the policy. A fire during an undocumented impairment is the scenario adjusters are trained to find, and deny.
Sprinklers are the reason most commercial fires stay small. While they are down, whatever starts, spreads — with your people inside. The watch exists so someone notices in minutes, not when the glow reaches the street.
What a fire watch actually is
A fire watch is a person — dedicated to nothing else — continuously patrolling a building or site to detect fire, smoke and hazardous conditions while the systems that normally do that job are out of service, ready to call the fire department and start an evacuation the moment something is wrong. It exists because a building without working sprinklers or alarms has lost its automatic detection and suppression, and the code's answer is to replace the electronics with trained human vigilance until the system is back. It is a compliance post with a log the fire marshal will read — not a standard guard shift under a different name.
When Texas requires one
The trigger most operators meet is the impairment rule: under the fire code in force across the major Texas jurisdictions, when a required fire alarm or sprinkler system is out of service for more than four hours in a 24-hour period, the building must be evacuated or an approved fire watch established until the system is restored. Beyond impairments, fire watches are required around hot work such as welding and torch-applied roofing, ordered by fire marshals for large assemblies and events where protection is inadequate, and imposed as a condition of occupancy on construction sites and buildings operating before their systems are fully commissioned.
Who sets the rules: your AHJ
Texas fire code authority is local. Houston, Dallas, San Antonio, Austin and Fort Worth each enforce their own adopted edition of the International Fire Code with local amendments, and their fire marshals — the authority having jurisdiction, or AHJ — decide what your fire watch must look like: patrol frequency, log format, staffing level, and when it can stand down. In unincorporated areas and state-owned buildings, the State Fire Marshal's Office fills the role. The operational takeaway is simple: call your local fire marshal the moment an impairment starts, and get their fire watch requirements in writing.
The four-hour rule in practice
The clock starts when the system goes down, not when procurement approves a vendor. Out of service means exactly that: an alarm panel in trouble that cannot report, a closed sprinkler control valve, riser or pump work, a fire pump without power. Planned impairments — testing, tenant improvements, repairs — should have the fire watch arranged before the valve closes. Unplanned ones start a four-hour countdown during which you notify the fire department, notify your insurance carrier, and either restore the system, empty the building, or have a watch standing. Waiting to see whether the repair runs long is how buildings end up cited and uninsured on the same afternoon.
What the officer on watch must do
A compliant fire watch is continuous and dedicated: patrols through all affected areas on a route and frequency the AHJ accepts — hourly rounds are a common floor, tighter for hot work and assemblies — with no other duties assigned. The watch carries a reliable means of alerting the fire department, knows the locations of exits, extinguishers, alarm points and hydrants, has the authority and the means to start an evacuation, and understands that the job on discovering fire is call, alert, evacuate — not fight. Every round goes into the log with a timestamp. An officer doing fire watch as a side duty to a normal post is, in the code's eyes, no fire watch at all.
The log your fire marshal expects
The fire watch log is the compliance artifact, and inspectors read it. It should show the building, the impaired system and why, when the impairment began, who ordered the watch, the name and contact for each person standing it, every patrol round with its time and areas covered, every hazard observed and what was done about it, all communications with the fire department and the AHJ, and when — and on whose authority — the watch ended. Keep it on site and current: an inspector arriving mid-impairment will ask for it before anything else. SECURICO fire watch posts log rounds digitally with GPS timestamps, so the record exists whether or not anyone remembered the clipboard.
Hot work: the other fire watch
Welding, cutting, grinding and torch-applied roofing carry their own requirement: a fire watch during the work and for at least 30 minutes after it ends — and many AHJs and insurance carriers now expect a full hour — because smoldering ignition in walls, insulation and debris shows up after the torch stops. The hot-work watch stays within sight of the work area, holds an extinguisher and knows how to use it, and has no other job. On construction sites this is routinely bundled with site security, so the same licensed officers cover the torch schedule by day and the perimeter by night.
Can your own employee stand the watch?
Sometimes — and it is usually a false economy. Many Texas AHJs will accept a trained, dedicated employee for a short planned impairment, provided they are genuinely relieved of all other duties, trained on the route and the log, and documented to the fire marshal's satisfaction. The math breaks on anything longer: an around-the-clock impairment needs three shifts of coverage plus relief, which is staffing you do not have spare, performing a compliance task your team has never been audited on. Companies providing guard services in Texas must be licensed by DPS — SECURICO operates under DPS B30995401 — and a licensed provider brings the training, the backfill and a log that survives inspection.
How long it runs — and who ends it
The watch runs until the impaired system is restored, tested and back in service, and the AHJ — not the repair contractor — decides when that is. Standing down because the sprinkler company left at 5 p.m. with the system still awaiting inspection is one of the classic citations. Get the release from the fire marshal explicitly, record it in the log with a name and a time, and only then pull the post. If a repair stretches from days into weeks, expect the AHJ to revisit patrol frequency and add conditions — long impairments draw more scrutiny, not less.
What a fire watch costs in Texas
Fire watch bills like standard unarmed guard coverage in most Texas markets — typically $25 to $40 per hour depending on metro and shift — with the real cost driven by duration: a 24/7 watch is 168 hours a week, so a two-week impairment at $30 runs about $10,000. That number annoys everyone until it is set against the alternatives: citations and a possible vacate order from the AHJ, a carrier denying a fire claim on an unprotected building, and the fire itself. An exact quote for fire watch takes about sixty seconds online, and the number costs nothing.
Standing one up fast
When the four-hour clock is running, speed is the requirement. SECURICO deploys licensed fire watch officers same-day across Houston, Dallas, Fort Worth, San Antonio and Austin, and statewide beyond them — our Texas coverage page lists every metro. Have three things ready when you call or quote: the address and what the building is, which system is impaired and the expected duration, and anything the fire marshal has already specified. Written post orders, the patrol route and the log format are set before the first round, and our fire watch services page covers the offering in full.
Texas fire watch triggers at a glance
| Situation | What the code expects | How long |
|---|---|---|
| Sprinklers out over 4 hours | Notify the fire department; evacuate or establish an approved fire watch | Until restored, tested and released by the AHJ |
| Fire alarm out over 4 hours | Same impairment rule — detection counts as much as suppression | Until restored and released |
| Hot work — welding, cutting, torch roofing | Dedicated watch with an extinguisher, within sight of the work | During the work plus 30–60 minutes after |
| Large events and assemblies | Fire watch where the fire marshal orders one for the occupancy or conditions | Duration of the event, as ordered |
| Construction and early occupancy | Watch imposed as a condition where systems are incomplete | As the AHJ directs — often nightly until commissioning |
