Mohali's Nine New Sectors: Which Are Residential, Which Are Industrial, and Why It Matters

What is planned where

You will also see a larger figure quoted — roughly 11,103 acres across Greater Mohali and New Chandigarh, for seven new townships, seven new sectors and three Aerotropolis pockets. That is a wider programme than the nine sectors above, not a contradiction of it. When someone quotes an acreage at you, ask which of the two they mean.

Why the land use matters more than the sector number

Sector numbers in Mohali run in a grid, and a buyer naturally reads 101 and 103 as neighbours of 100 and 104 rather than as a designation. They are a designation.

Three practical consequences:

1. An industrial sector changes what is next door. Goods traffic, working hours, and the kind of commercial that grows around it. For an investor buying warehousing or a small unit, that is the point. For a family buying a first home, it is a thing to know before, not after.
2. Institutional and commercial sectors are what make residential ones work. Sector 84 as institutional and 87 as commercial is the reason 120–124 can be planned as residential at that scale. Schools, colleges and offices nearby are a feature, and they arrive on their own timeline.
3. Residential supply of 1,890 acres is a lot of supply. Five contiguous sectors released over the same period will compete with each other, and with existing stock in 76–80. That is good for a buyer and worth thinking about carefully if you are buying to resell.

The timing question nobody answers directly

All of this is planned, and much of the land is still moving through acquisition or pooling. The notices GMADA published on 14–16 September 2026 for villages around Banur and Mullanpur are part of that same process, and its pace is set by objections, awards and litigation rather than by a launch calendar.

For a sense of the real timeline: Aerotropolis Blocks A to D account for roughly 1,700 acres already acquired, while E to J are still moving — and a four-year dispute over about 240 acres held up Letters of Intent to farmers along the way. IT City, laid out over 1,700 acres years ago, still generated a civil writ petition notice on 15 September 2026.

None of that means the sectors will not happen. It means the gap between a notified sector and a liveable one is measured in years.

If you are buying in or near a planned sector

1. Confirm the land use for that specific sector, in writing, and for the pocket your plot sits in — not for the sector number in general.
2. Ask what exists today. Roads, water, power, and how many occupied homes. A plan is not an amenity.
3. Check whether it is an allotted GMADA plot or a private colony, and in the second case whether the colony is licensed and RERA-registered. These are different products with different risks.
4. Price it as farmland-adjacent land with a plan attached, because until services arrive that is what it is. If the plan lands early, that is upside you did not pay for.
