Verify against the latest gazette of the Delhi Fire Service (DFS) and the local Fire Authority interpretation before stamping drawings. Send the project drawings and we will mark up the fire-safety scope with citations within two working days.
· Why local-rule resolution matters
A residential developer planning an 18-metre block in Delhi would, on the NBC 2016 baseline alone, scope sprinklers, addressable fire alarm and wet-riser. Layer on the Delhi Fire Service (DFS) rule and at least 1 additional system trigger appear at this height. Getting that list right at design stage is what stops a tendered building from needing a second-round retrofit at OC stage.
· Frequently asked
Delhi Fire-Safety —
what people ask first.
What height triggers a sprinkler system in Delhi?
In Delhi, an automatic sprinkler system (IS 15105) becomes mandatory for residential and mixed-use buildings above 15 m height. This matches the NBC 2016 baseline. Source: Delhi Fire Service Act 2007; DFS NOC mandatory above 15 m..
Is voice-evacuation PA mandatory in Delhi?
Voice-evacuation PA (EN 54-16 / IS 14735) is mandatory in Delhi for buildings above 17.5 m, plus all assembly and hospitality occupancies regardless of height. This is six metres below the NBC 2016 baseline of 24 m — a significant scope addition for mid-rise buildings.
Who issues the Fire NOC in Delhi?
Delhi Fire Service (DFS) issues the state Fire NOC for new construction and occupancy. Most Delhi jurisdictions require both a design-stage Fire NOC (against drawings) and an occupancy-stage Fire NOC (against the installed system) before the local body issues an occupancy certificate.
What is the local override against NBC 2016 in Delhi?
Voice-evacuation PA from 17.5 m (NBC: 24 m). DFS independently inspects every renewal and refuses occupancy certificates without a documented test report.
