When Is Fire Watch Required?

Fire watch requirements are set by the authority having jurisdiction, insurers, and the specifics of the impairment. Here is how to determine what applies to your property.

Whether a fire watch is required is not a question with a single national answer. Requirements vary by jurisdiction, by the type of building, by the kind of impairment, and by the conditions an insurance carrier places on a policy. The consistent principle is that when fire detection or protection is impaired, someone may need to maintain a human watch until it is restored. The property owner or manager is responsible for confirming the specific requirements that apply to their site. This article explains the general factors involved so a property can ask the right questions, but it does not replace confirmation from the local authority.

The Authority Having Jurisdiction Decides

The agency with fire or building code authority over a property, often called the authority having jurisdiction or AHJ, sets the local requirements. That may be a city or county fire department, a fire district, or another agency, and its expectations can differ from a neighboring jurisdiction. Because the requirements are local and can change, the property should contact its AHJ directly to confirm whether a fire watch is needed, what it must cover, and how long it must remain in place. Contact information for the AHJ is usually available through the city or county website, and the property's insurer can often clarify its own expectations at the same time.

Because requirements are set locally, two similar buildings in different cities can face different expectations. A property that has recently changed ownership, use, or occupancy should be especially careful to confirm current requirements rather than relying on what applied before. Keeping a record of who was contacted at the AHJ, when, and what they said is also useful if the impairment lasts several days.

Situations That Commonly Trigger a Fire Watch

• A fire alarm or detection system taken out of service for repair or testing.
• A sprinkler or suppression system shut down because of a water supply problem or maintenance.
• Hot work such as welding, cutting, or grinding in or near combustible materials.
• Construction or renovation that disrupts existing detection or protection.
• A fire or system failure that leaves a building without normal protection.
• Vacant or unoccupied buildings where an owner or insurer wants a physical presence.

Insurance and Property Requirements

Beyond the AHJ, an insurance carrier may impose its own conditions. A policy can require a watch during a system outage, specify how often rounds must be made, or require written documentation of the watch. Lease agreements and lender requirements can add further conditions. The property should review its policy and any lease obligations, because a requirement that comes from an insurer is just as binding on the property as one that comes from a code official. Properties should keep copies of any written direction they receive, whether from the AHJ or the carrier, so the basis for the watch is clear.

How to Confirm What Applies to Your Property

The practical sequence is to identify the impairment, contact the AHJ to confirm what it requires, check the property's insurance policy and any lease obligations, and arrange a documented watch that meets the strictest applicable standard. Because the details vary, a property should not assume that a requirement from another building or another city applies to its own situation. When in doubt, confirming directly with the AHJ is the safest step. If an insurer and the AHJ appear to require different things, the property should satisfy the stricter of the two and document that decision.

Once the requirements are confirmed, arranging coverage is usually straightforward. A licensed security provider can staff a documented fire watch and adjust the schedule as the impairment changes, then stand down once the systems are back in service and the AHJ or insurer agrees the watch is no longer needed.
