Fire NOC and Fire Licence in Tamil Nadu

What Tamil Nadu Fire and Rescue Services approves

Fire compliance for an industrial building in Tamil Nadu works in layers, and much of the confusion in practice comes from treating them as one. The first is the set of fire-safety provisions the building itself must meet, which come from the building rules and apply whether or not anyone issues you a certificate. The second is the Fire and Rescue Services no-objection certificate (NOC) taken at the planning stage, before the building goes up. The third is the Fire Licence, granted once the building is complete and the fire systems are in, and renewed after that for as long as you operate.

The statutory basis for the department's clearances is the Tamil Nadu Fire Service Act, 1985. Tamil Nadu Fire and Rescue Services (TNFRS) treats section 13 of that Act, which lets the Government require fire precautions for premises by notification, as the source of its power to issue the NOC and the Fire Licence. A new Tamil Nadu Fire and Rescue Services Act was passed in 2025, but it has not been brought into force, so the 1985 Act still governs.

None of these clearances is part of planning permission or the building permit covered on construction and building approvals. CMDA or DTCP granting planning permission does not carry fire clearance with it, and a building permit is not a substitute for either fire approval. They are separate approvals that plug into the construction timeline at particular points.

Why height is the wrong starting point for a factory

It is common to hear that fire approval only matters once a building crosses 18.3 metres. For an industrial site that is simply wrong. Rule 64 of the Tamil Nadu Combined Development and Building Rules, 2019 (TNCDBR) requires every building, in its design and construction, to provide for the safety of occupants from fire, smoke and panic, with automatic detection and alarms where the building is large enough that a fire would not otherwise give warning (TNCDBR 2019, rule 64(1)). Fire protection and extinguishing systems must follow accepted standards and good practice under the National Building Code (rule 64(2)). And the buildings to which these fire-protection requirements expressly extend include high-rise buildings of 18.30 metres and above, public buildings, malls, cinemas, wedding and community halls, buildings where explosives, crackers or other inflammable materials are handled or traded, and all categories of industries and warehouses (rule 64(3)).

The 18.3 metre figure matters for a different reason. The rules define a high-rise building as one exceeding 18.30 metres (rule 2(58)), and for high-rise buildings they make the fire systems subject to the satisfaction of the Director of Fire and Rescue Services through an NOC (rule 39(11)(iii)). Industrial buildings, however, are themselves capped at 18.30 metres under the planning parameters for industries (rule 36), so most factories and warehouses will never be high-rise buildings at all. For them, height decides which TNFRS office handles the file. It does not decide whether fire compliance applies.

Protection measures, the NOC and the Fire Licence

The distinction matters because a duty in the first row is not, by itself, a duty to obtain a separate NOC. Rule 64 tells you what the building must contain. Whether a particular approval also has to be taken from TNFRS, and at which stage, depends on the building's height, its occupancy and the procedure that applies to it. For a manufacturing unit, though, it is unusual to escape both clearances: the Single Window procedures for the planning-stage NOC and for the Fire Licence are each written for manufacturing units of every size, and the version for buildings under 18.3 metres is handled by the District Officer.

What it costs to get wrong

Occupying or running a building without the fire clearance it needs is enforceable under the Tamil Nadu Fire Service Act, 1985 and under the planning and building law that makes fire compliance a condition of approval. In practice the more immediate cost is that other approvals stall: a completion certificate, a factory licence or a bank's disbursement can wait on the Fire Licence. A building that was designed without its fire provisions, because the owner assumed fire only mattered above 18.3 metres, is expensive to retrofit and can fail the licensing inspection outright. This page does not state penalty figures.

The process

1. Design the fire provisions into the building

   Before the plans go anywhere, settle the fire design that rule 64 and, for a high-rise building, rule 39 require: detection and alarm, hydrants and extinguishers, escape routes, compartmentation and access for fire tenders. The proposed building plan and the proposed fire plan are the documents TNFRS will look at first, so they need to agree with each other and with what you intend to build.

2. Take the planning-stage NOC

   Apply online through the Tamil Nadu Single Window Portal or TNFRS's own system, which routes the file to the right office. For a building under 18.3 metres, the District Officer scrutinises the application, an Assistant District Officer or Station Officer inspects, and the District Officer approves or rejects. The published procedure indicates 15 days from receipt of a complete application, and the documents it asks for are proof of title or lease, the proposed building plan and the proposed fire plan, each certified by an engineer on the local body's panel. A multi-storeyed building goes to the Director. The procedure sheets show no fee for either. These periods are departmental service targets, not statutory deadlines, and they run from a complete file.

3. Build to the approved fire plan, then apply for the Fire Licence

   Once construction is complete and the systems are installed, apply for the Fire Licence. For a building under 18.3 metres the District Officer again decides, after an inspection, within an indicated 15 days, and the application needs a copy of the planning-stage NOC, your title or lease, and the building plan approved by the local body, DTCP or CMDA. For a multi-storeyed building the Director decides, after an inspection by the zonal Joint or Deputy Director, within an indicated 30 days, on the basis of the department's compliance certification, your title or lease and the approved building plan. Approval issues as a digitally signed licence. The inspection is checking that what was built matches what was approved, so deviations made on site without a revised NOC are the usual reason a file comes back.

4. Renew the Fire Licence before it lapses

   The Fire Licence has to be renewed to stay valid for continuing operations. Renewal asks for less than the original application: for a multi-storeyed building, the approved building plan and the existing licence. How often renewal falls due is not stated on this page. Confirm the interval from your licence and the current TNFRS instruction before you diary it, and treat any change to the building, the occupancy or the stored materials as a reason to check whether the licence still covers you.

How this fits with planning permission and the building permit

Where the planning rules require fire clearance before planning permission or building-plan approval, take the planning-stage NOC on that track first, so that the drawings the planning authority approves are drawings TNFRS has already accepted. The Fire Licence comes later, after construction and before occupation or operation. Fire approval is TNFRS's own decision on its own track, even where a single portal collects the applications together, and CMDA, DTCP or the local body does not issue it on TNFRS's behalf.

Petroleum installations: TNFRS and OISD

A retail fuel outlet or a petroleum depot or terminal has to satisfy two sets of fire requirements. The TNFRS NOC and Fire Licence above are the statutory approvals, and alongside them the installation is expected to meet the fire-protection standards published by the Oil Industry Safety Directorate, principally OISD-STD-225 for retail outlets and OISD-STD-244 for depots and terminals. OISD does not grant approvals itself: its standards are the design and operating baseline that PESO and TNFRS expect a petroleum installation to meet, while the licences remain with PESO and TNFRS respectively. The petroleum-licensing side is covered in the PESO page's OISD section.

Common failure points

• Treating fire as a high-rise issue. Rule 64 brings all industries and warehouses within the fire-protection requirements regardless of height, and TNFRS runs an NOC and a Fire Licence for buildings under 18.3 metres. A low-rise factory designed on the assumption that fire does not apply to it is the most expensive version of this mistake.
• Confusing a fire-protection duty with an NOC. The building rules say what the building must have. The NOC and the Fire Licence are the department's clearances, and each has its own stage and documents.
• Taking the NOC after the plans are approved. Where fire clearance is a precondition of planning permission, getting it afterwards means reworking drawings that have already been approved.
• Applying for the licence before the building matches the approved fire plan. The licensing inspection checks exactly that, and site changes made without a revised NOC are the commonest reason for rejection.
• Letting the Fire Licence lapse. Continuing operation depends on a current licence, not on the original approval.
• Blocking escape routes or fire equipment with stored material between inspections, which is one of the most frequent findings on repeat visits.
