Applicability
Which buildings need an ACMS?
Rule 37 does not apply to every building in Delhi. It applies to the occupancy classes listed in Rule 27, sub-rules (2) to (12) — the classes the rules treat as likely to carry a risk of fire. Each class has its own trigger. Here is the whole table, in plain terms.
| Rule 27 | Occupancy class | Trigger threshold |
|---|---|---|
| (2) | Residential — other than hotels and guest houses | Above 15 m, or 5 storeys or more |
| (3) | Hotels and guest houses | Above 12 m, or 4 storeys or more |
| (4) | Educational — schools, colleges, coaching | Above 9 m, or 3 storeys or more |
| (5) | Institutional — hospitals, care, custodial | Above 9 m, or 3 storeys or more |
| (6) | Assembly — halls, cinemas, places of worship, banquet | All assembly buildings. No height or area threshold |
| (7) | Business — offices | Above 15 m, or 5 storeys or more |
| (8) | Mercantile — shops, malls, showrooms | Above 9 m, or 3 storeys or more |
| (9) | Industrial | Covered area over all storeys above 250 m² |
| (10) | Storage — warehouses, godowns | Covered area over all storeys above 250 m² |
| (11) | Hazardous | All hazardous occupancies above 100 m² |
| (12) | Underground structures | 2 levels or more |
Context
How ACMS fits the rest of the regime.
The monitoring obligation does not stand alone. It sits underneath the certificate and declaration machinery that the rules already run on.
The certificate
Fire safety certificate
An empanelled fire safety auditor inspects the building and issues the certificate, with the accompanying declaration and inspection report.
The annual filing
The yearly declaration
Each year a declaration is filed confirming the fire and life-safety measures have been maintained in good working order. It is a statement about the whole year, not about the day of inspection.
The evidence
What ACMS is for
A continuous record is what turns that annual statement from an assertion into something supportable. This is the gap the monitoring requirement closes.
If you are not sure
Borderline cases are common.
Mixed-use buildings are the usual difficulty — a tower with retail at the base, offices above and a banquet hall on one floor can engage more than one class at once, and the strictest applicable trigger is the one that matters.
Podium levels, stilt parking, service floors and basements all affect the count. If your building sits near a line, the honest answer is that it needs looking at rather than guessing at, and we are happy to do that without obligation.
Do all assembly buildings really need it?
Yes. Assembly occupancy is listed with no height or area threshold attached, so the class is caught as a whole rather than only its larger examples.
Does a five storey housing society qualify?
Residential buildings other than hotels are caught above 15 metres, or at five storeys or more. The two limbs are alternatives — a five storey society is inside the rule even if it stands under 15 metres.
Does this apply outside Delhi?
This particular obligation is made under the Delhi Fire Service Rules and applies in the NCT of Delhi. Other states run their own fire rules. We work across India on fire systems generally, so a building elsewhere is still worth a conversation — it simply is not caught by this rule.
We already have a fire alarm system. Is that enough?
No, and the two are different things. Your alarm system detects a fire and warns people. The monitoring requirement is about proving, continuously, that the alarm system and the pumps, tanks, risers, PA and pressurisation fans behind it are all in working order on an ordinary day when nothing is happening.

Find out where your building actually stands.
A survey walks your building against the twenty mandated points and tells you which you already satisfy and which need work. No obligation, and you keep the findings either way.
