Updated 27 October 2026. We read CAQM-schedule explainers, the Stage 1 coverage and the revised-GRAP reports. This guide adds what the ranking pages leave out: what GRAP means for an under-construction flat, for your society's diesel generator, and what to ask a developer this winter.

When was GRAP Stage 1 invoked in Gurugram?

On 21 October 2026, 'with immediate effect', after forecasts showed poor air would persist (Business Today, 22 October 2026). That day's bulletin listed Delhi at 245, Greater Noida 280, Noida 249, Ghaziabad 223, Gurugram 216 and Faridabad 123 (Business Today). The stages are triggered by Delhi's AQI but apply across the NCR, including Gurugram, Faridabad, Ghaziabad and Gautam Buddh Nagar (DesiMachines, 10 October 2026). Readings move daily, so check CAQM's current order rather than relying on a single day's number.

GRAP stages and AQI thresholds

  • Stage 1, Poor, AQI 201–300: construction continues under dust controls (DesiMachines; Aceget, 1 September 2026).
  • Stage 2, Very Poor, AQI 301–400: no new construction ban; Stage 1 rules continue with more inspection (DesiMachines; Aceget).
  • Stage 3, Severe, AQI 401–450: earthwork, piling, demolition, open-trench utility work, brick and masonry, RMC batching plants and major welding stop, except on exempt projects (DesiMachines).
  • Stage 4, Severe Plus, AQI above 450: linear public projects such as highways, flyovers and pipelines lose their Stage 3 exemption (DesiMachines).

What changed in the revised GRAP from 1 October 2026

CAQM's revised schedule has 48 actions: 25 under Stage 1, 8 under Stage 2, 10 under Stage 3 and 5 under Stage 4 (Sunday Guardian). Two shifts matter for Gurugram residents: rules on diesel generator sets moved from Stage 2 to Stage 1, and restrictions on BS-IV and older buses from the NCR and neighbouring states also moved to Stage 1 (Sunday Guardian). The Stage 3 curb on BS-III petrol and BS-IV diesel cars covers Gurugram, Faridabad, Ghaziabad, Gautam Buddh Nagar and now Sonipat (Sunday Guardian).

The wider November–January curbs reported alongside, including a prohibition on dust-generating demolition and outdoor civil construction from 1 November and a complete construction-and-demolition ban from 10 December to 20 January, are described as part of Delhi's winter plan (Sunday Guardian). We found no report extending those Delhi dates to Gurugram; treat them as Delhi-only unless Haryana or CAQM orders otherwise.

Is construction banned in Gurugram under Stage 1?

No. Under Stage 1, work that complies with its permissions and pollution-control norms is allowed, while open burning and dust-generating work that breaches the controls is not (Business Today). The site obligations that apply from Stage 1 onwards:

  • Projects on plots of 500 sq m or more must be registered on the state or Delhi portal for remote dust monitoring; work should not be permitted on qualifying projects that are not registered (DesiMachines).
  • Construction material and C&D waste stored covered and moved only in covered vehicles (DesiMachines; Business Today).
  • Dust kept within site boundaries, with anti-smog guns in proportion to the project's built-up area (DesiMachines).
  • An Integrated Command and Control Centre is monitoring construction-related pollution (Business Today).

Which projects keep working at Stage 3?

Restricted activities may continue, with dust-control compliance, on railway, metro, airport and inter-state bus terminal projects; national security and defence; projects of national importance; hospitals and healthcare; linear public projects; and sanitation such as sewage treatment and water supply (DesiMachines). Private housing is not on that list, so a Stage 3 order would pause most structural work at residential sites in Gurugram. At Stage 4, linear projects such as roads and flyovers also stop (DesiMachines).

Society diesel generators: the rule most residents miss

Generator rules now start at Stage 1. Under the CAQM direction summarised by DesiMachines (Direction No. 76, 29 September 2023): gas-based sets of any capacity, sets up to 800 kW meeting MoEFCC standards, and sets of 800 kW and above with a prescribed emission-control system have no restriction; sets from 41 kW to under 800 kW must run in dual-fuel mode or have certified retrofitted emission-control devices; sets from 19 kW to under 41 kW need dual-fuel mode; and portable sets under 19 kW are generally not permitted except for emergency services.

This matters in Gurugram, where many societies run on diesel backup during outages. Public infrastructure is adapting too: NHAI has begun fitting retrofit emission-control devices on 25 diesel generator sets used for lighting on the 8.7 km Package IV stretch of the Dwarka Expressway, from Basai to the Kherki Daula cloverleaf, in line with CAQM's measures (PropNewsTime, 23 October 2026).

  • Ask your RWA or maintenance agency the capacity of each society generator and whether it has a retrofit device or dual-fuel kit.
  • If you are buying a resale flat, ask whether backup was ever curtailed during last winter's GRAP stages.
  • For a new project, ask the developer what backup technology is specified and whether it is GRAP-compliant.

Does GRAP delay possession of an under-construction flat?

Stage 1 should not, because work continues. A Stage 3 or 4 order can stop structural work for days or weeks. Whether those days extend the promised possession date depends on the force majeure clause in your builder-buyer agreement and, in a dispute, on how HRERA reads it; we did not find a 2026 HRERA order setting a general rule, so do not assume either way. Practical steps:

  • Read the force majeure clause in your agreement and note whether it names government or court orders on pollution.
  • Keep the CAQM orders' dates. If a developer later cites GRAP for a delay, you can match the claim to the days restrictions were actually in force.
  • Compare the agreement's possession date with the completion date on the project's HRERA registration.
