Title card reading Is a Fire NOC mandatory for a warehouse, with a simple outline of a racked warehouse interior and a fire-safety shield — Title card. Not a photograph of a Secured Engineers site.

Usually yes. Warehouses are storage occupancies, and fire authorities set the NOC trigger by covered area, height and state rules. In Delhi, storage buildings with more than 250 square metres of covered area across all floors need clearance under Rule 27 of the Delhi Fire Service Rules. Other states set their own thresholds, so confirm yours before you build.

What triggers a Fire NOC for a warehouse?

Delhi Fire Service's published FAQ lists the buildings covered by Rule 27. For storage the entry is storage buildings with a covered area on all floors of more than 250 square metres; industrial buildings share that figure, and hazardous buildings are caught at more than 100 square metres. The same list brings in mercantile buildings above 9 metres and all assembly buildings, which matters for a warehouse with a retail or showroom floor. The FAQ confirms that Delhi follows the 2016 Unified Building Bye-Laws and the National Building Code of India 2016 published by BIS.

Outside Delhi the structure is the same but the numbers differ. Our state data records the Punjab Fire and Emergency Service Act, 2024, the Haryana Fire and Emergency Services Act, 2022 and the Uttar Pradesh Fire and Emergency Services Act, 2022 as the governing laws, with Rajasthan granting Fire NOCs under its municipalities law. The thresholds sit in the rules and building bye-laws under those laws, and we do not quote them here without the text in hand. See our Fire NOC guide for Punjab, Haryana and UP for the process.

Three things change applicability. Covered area includes every floor and any mezzanine. What you store matters as much as the shed: Delhi's own classification lists godowns and warehouses holding non-combustible goods among low-hazard industrial occupancies, while a warehouse holding chemicals or solvents can be a hazardous building with a lower trigger. And a change of use or expansion reopens the question, as we explain in when expansion triggers a new Fire NOC.

How do storage hazard and racking change the fire scheme?

Warehouse type	How it is likely to be classified	What changes in the scheme
Floor-stacked non-combustible goods (metal parts, ceramics) in a single-span shed	Low-hazard storage or industrial; confirm with the authority	Hydrant ring, tank and pumps; sprinklers still driven by pallets, packaging and vehicles at the docks
Racked general goods in cartons and on pallets	Storage occupancy, ordinary hazard or higher	Sprinkler density set by rack height and commodity class; possible in-rack protection; larger tank
Plastics, foam, paper, textiles or FMCG packaging, racked high	Higher hazard storage	Higher sprinkler density, higher-flow heads, bigger pumps and water storage, tighter detection
Chemicals, solvents, aerosols, gas cylinders	Hazardous building; Delhi's trigger is 100 sq m	Segregation, drainage and containment, specialised extinguishing, a separate scheme
Cold store with insulated panels	Storage with a combustible envelope	Protection for the panel core, ammonia or refrigerant plant rooms, detection above and below ceilings

The table is a guide to the direction of change, not a classification. The authority classifies the building from the stored goods and layout you declare, and the hazard class decides the design. Our glossary note on sprinklers makes the same point: design to IS 15105 is hazard-based, and racking height and commodity class can push a simple warehouse into demanding design. The classic rejection is a racked store declared as ordinary industrial. Read the racking compliance trap and why grade-A warehouses fail fire audits before you finalise the layout.

Site layout matters as much as the pipework. Delhi's bye-laws call for a hard-surface fire tender road of 6 metres for buildings up to 40 metres in height, and the fire plan must show the pump house with direct access, the tanks and the hydrants. On a dock-side warehouse the long face is the truck lane, so hydrants and the pump house are better reached from the ends. Lighting and sprinklers also compete for the same space under the roof, which needs one coordinated layout.

Water is the other sizing question. Delhi Fire Service says pump capacity is fixed by the actual discharge the design requires under IS 15105 and Part 4 of the NBC, taking the higher value, and that the fire water tanks are replenished at 1,000 litres per minute. A higher storage hazard means a higher sprinkler density, so a bigger tank and pumps, and tanks and pump house are civil items that are expensive to move once the slab is cast. Settle the stored commodity and the rack heights before the civil design is frozen, not after.

What is the process and what does the inspection check?

Delhi Fire Service describes two stages: fire recommendations before construction, once the plans are approved, and a Fire Safety Certificate after construction and before occupancy, once all the recommended systems are verified. For a Rule 27 building the Delhi certificate is valid for three years if non-residential, with renewal applied for at least six months before expiry. Delhi Fire Service states that it charges no fee for plan approval, the certificate or its renewal; check the schedule in your own state.

At inspection, expect the officer to want to see the pumps start in sequence, hydrants flowing at the farthest point, the sprinkler flow test, the alarm responding, exits and fire-tender access in place. The installation must match the approved drawings. If racking has been added or raised since, the file is out of date. Keep the commodity declaration, rack layout and test logs together.

What documents do you need?

Architectural plans with the fire control room, pump house, tanks, hydrants, ventilation cut-outs and fire shafts marked.
Sprinkler design calculations, schematic layout and plans, to IS 15105 in Delhi's case.
Smoke-control calculations, layouts and plans.
The application form, and ownership or allotment papers.
At stage two, completion and test records for the pumps, mains and alarms.

Delhi Fire Service says plans normally reach it through the building sanctioning authority. Our Fire NOC calculator maps a building to the likely requirement, and the warehouse fire checklist lists what to prepare.

How Secured Engineers helps

We design the fire-fighting system in-house and file Fire NOC applications ourselves, with CEIG and DISCOM filings handled by the same team, and MEPF can sit under one contract. For a new single-span distribution warehouse at a rotavator-parts manufacturer in Ludhiana district, we delivered the electrical, ELV and fire-fighting package, with the fire protection designed for the stored hazard rather than for the steel on the racks; the record is on our project page. We work from offices in Noida (Delhi NCR) and Ludhiana, with 535+ projects across 18+ states and 89.77% repeat clients. See the warehouse MEPF contractor page.

If you have a recommendation letter, a layout with racking, or a renewal due, send the file for a review before you submit or build. See our Fire NOC assistance service, WhatsApp us, call +91 70099 85817, or ask for a free proposal.

Frequently asked

Is a Fire NOC mandatory for a small godown?

It depends on the state. In Delhi, Rule 27 of the Delhi Fire Service Rules, 2010 covers storage buildings with a covered area above 250 square metres on all floors, and hazardous buildings above 100 square metres. A smaller godown may sit below that line. Other states set their own thresholds in their fire rules and bye-laws, so ask the fire office for a written position.

Does a warehouse need sprinklers?

Often, and storage occupancies trigger them earlier than light industry because of fire load and stacking height. The authority's recommendation letter fixes the scope for your building. Delhi Fire Service names IS 15105 as the standard for sprinkler design and requires sprinklers in any basement above 200 square metres. Racking height and the goods stored decide the design density.

Does adding racking change the Fire NOC?

It can. Delhi Fire Service says its recommendations remain valid only until there is an addition, alteration or revision of the approved plan. Raising rack heights, adding a mezzanine or changing the commodity stored changes the fire load the scheme was designed for, so check with the fire office or your fire consultant before the change, not after the next inspection.

How long is a warehouse Fire Safety Certificate valid?

In Delhi, a Fire Safety Certificate for non-residential buildings is valid for three years, and renewal must be applied for at least six months before expiry. Other states set their own validity. Our state guide records one to five years as common. Put the expiry date from your certificate in the maintenance calendar.

Who is responsible for the fire systems in a leased warehouse?

Delhi Fire Service says the onus of installing and maintaining the fire safety systems lies on the owner or occupier, and that any loss from non-functional systems is borne by them. Between landlord and tenant, the lease should say who obtains the NOC, who keeps the systems tested and who pays for upgrades when stock changes.

What documents are needed for the first stage?

In Delhi, architectural plans marking the fire control room, pump house, tanks, hydrants and ventilation cut-outs; sprinkler design calculations with schematic layout; smoke-control calculations with layouts; and the application form. Plans normally go through the building sanctioning authority. Other states ask for similar sets under their own forms.
