You scheduled your annual fire sprinkler inspection, the technician came out, and now you’re holding a report with a list of deficiencies. For a lot of Denver property managers, this is where things get confusing. What exactly is a deficiency? How serious is it? Who fixes it, and how fast? What happens if you don’t? The answers depend on what type of deficiency you’re dealing with, and understanding the difference matters more than the length of the list.
Not All Deficiencies Are Equal
NFPA 25, which governs fire sprinkler inspection and maintenance across Colorado, requires inspection reports to classify deficiencies by severity. The 2026 edition formalizes this further, requiring reports to document completed procedures, test results, deficiencies, impairment notifications, and repair activities. In practice, deficiencies fall into three categories:
Critical deficiencies render the system impaired or non-functional. A closed control valve, a disconnected water supply, a broken dry pipe valve, or a sprinkler head that’s been painted over and can no longer activate all fall here. These require immediate action — not next week, not next quarter.
Non-critical deficiencies are real problems that need to be corrected but don’t disable the system today. Examples include corroded pipe fittings, missing FDC caps, sprinkler heads with minor physical damage, gauges reading out of acceptable range, or a control valve with a broken tamper switch. These need to be repaired on a defined timeline, typically within 30 days for most AHJs in the Denver metro.
Recommendations are observations that don’t rise to a code deficiency but represent conditions the inspector thinks you should know about. A recommendation might be noting that storage is getting close to the 18-inch clearance required below sprinkler heads, or that a gauge is trending toward the edge of its acceptable range. These aren’t violations, but ignoring them long enough can turn them into deficiencies at the next inspection.
Who Decides the Timeline
Two parties have authority over your deficiency timeline: your AHJ and your insurance carrier. They don’t always agree.
The AHJ (Authority Having Jurisdiction — in most Denver properties, the Denver Fire Department) sets the compliance window for deficiencies identified during inspections it oversees or reviews. Denver typically expects non-critical deficiencies to be corrected and documented within 30 days. For critical deficiencies involving an impaired system, the expectation is same-day action and formal impairment notification.
Insurance carriers sometimes have stricter timelines. FM Global, Travelers, and other commercial property insurers conduct their own inspection programs and may give you a shorter window — or flag an uncorrected deficiency at renewal. If your property has a carrier-specific inspection program, read those requirements separately from your NFPA 25 report.
When the two conflict, the stricter timeline controls.
What “Impaired System” Means and Why It Matters
A critical deficiency that disables all or part of your sprinkler system triggers the impairment process under NFPA 25. An impairment isn’t just a paperwork event — it requires specific steps.
The building owner or responsible party must notify the AHJ, the insurance carrier, and in some cases the local fire department that the system is out of service. Depending on occupancy type and local AHJ requirements, a fire watch may be required: a person physically walking the affected areas at defined intervals while the system is down.
Fire watches are operationally disruptive and expensive in staff time. The best way to avoid them is to catch critical deficiencies before they become complete system failures — which is exactly what regular NFPA 25 inspections are designed to do.
The Most Common Deficiencies in Denver Commercial Buildings
After years of inspecting sprinkler systems across the Front Range, a few deficiency types come up consistently:
- Painted or corroded sprinkler heads. A head that’s been painted over during a renovation can’t activate properly. These must be replaced, not cleaned.
- Storage within 18 inches of sprinkler heads. Tenants stack product, equipment, or supplies too close to the ceiling. This isn’t a sprinkler problem — it’s a building management problem that shows up on every inspection until it’s corrected.
- Missing or damaged FDC caps. The fire department connection couplings need caps to keep debris out of the system. Missing caps are one of the most common and easiest deficiencies to clear.
- Control valve position issues. A partially closed OS&Y (outside screw and yoke) valve or a butterfly valve without a tamper switch is a non-critical deficiency that escalates quickly if ignored.
- Gauges out of range. System pressure gauges that read outside the acceptable range may indicate a leak, a supply problem, or simply a failed gauge. Either way, it needs investigation.
Your Responsibilities as the Property Owner
Under Colorado law and NFPA 25, the building owner is responsible for the inspection, testing, and maintenance of the fire sprinkler system. The inspection contractor identifies deficiencies — fixing them is your obligation, not theirs, unless you’ve contracted them to do both.
When you receive a deficiency report, the clock starts. Keep a copy of the report and document every step: who you contacted, when you scheduled the repair, what was done, and when the system was returned to service. That documentation is what you hand to the AHJ or insurance carrier when they follow up.
If a deficiency is disputed — you believe the inspector was wrong, or you think a condition was misclassified — you can request a re-evaluation. Do that in writing, and don’t let the timeline slip while you wait for a response.
What This Means for Your Building
A deficiency report is not a crisis. It’s information, and acting on it promptly is straightforward. The properties that end up in trouble are the ones that file the report away and assume someone else is handling it.
