Answer
What is IFC 901.7?
By Price Protection SecurityReviewed TX DPS Lic #B09430601
Short answer
IFC 901.7 is the section of the International Fire Code titled Systems out of service. It requires that when a required fire protection system is out of service, the fire department and the fire code official are notified immediately, the building owner designates an impairment coordinator, impaired equipment is tagged and, where the official requires it, the building is evacuated or an approved fire watch is provided until the system is restored. Houston adopts the code with local amendments.

What the section covers
Fire protection systems the code requires a building to have: automatic sprinklers, fire alarm and detection, standpipes, fire pumps and related equipment. When any of them is out of service, planned or not, the section’s procedure applies. It does not distinguish between a two-hour valve closure for a tenant build-out and a riser broken by a contractor; both are impairments, and both trigger the same steps.
The steps
Notify the fire department and the fire code official immediately. Designate an impairment coordinator, the person responsible for managing the impairment. Tag the impaired equipment so nobody assumes it works or restores it unexpectedly. Follow the fire code official’s direction: where the official requires it, evacuate the building or provide an approved fire watch until the system is restored. Notify again when it is. The word “approved” means the authority decides what the watch looks like: who may perform it, the interval, the alarm method and the log.
Who applies it in Houston
The City of Houston adopts the International Fire Code with local amendments by ordinance, and the Houston Fire Marshal’s Office is the authority having jurisdiction. Editions and amendments change, so this site does not state a year; the office or counsel can confirm the current text for a building. Outside the city, county fire marshals and the smaller cities apply their own adoptions.
What it means in practice
A building with a system down is operating on a promise, and the fire watch is the promise kept visibly. Price Protection staffs approved fire watches on short notice with officers trained for it and a log the fire marshal can read. The IFC 901.7 article goes through the section clause by clause. This is a summary for planning rather than legal advice.
