Section 01What Is a GMADA Sector?

A “sector” is GMADA’s basic numbered planning unit — a defined, gridded parcel of the city assigned a specific land use under the master plan, similar in concept to Chandigarh’s original sector system. It’s distinct from a few related terms buyers often confuse:

• Sector — A numbered, boundaried planning unit with its own zoning
• Phase — An informal/colloquial name sometimes used for specific sectors (e.g., Sector 61 is commonly called “Phase 7” locally) — not an official GMADA planning category on its own
• Urban Estate — A broader developed township area, which may contain multiple sectors
• Planning Area / Local Planning Area (LPA) — The larger administrative planning zone (e.g., S.A.S Nagar LPA, Kharar LPA) within which multiple sectors sit
• Township — A GMADA-developed self-contained development (e.g., New Chandigarh/Mullanpur, Aerocity) which may use its own naming alongside or instead of sequential sector numbers

Section 02Sector Numbering — Why It Starts at 61

Mohali (S.A.S Nagar) was originally developed as a planned extension of Chandigarh, and its sector numbering continues sequentially from where Chandigarh’s own sector grid ends — Chandigarh’s sectors run roughly through the low 60s, so GMADA’s Mohali sectors begin at 61. As GMADA’s jurisdiction and townships expanded over the following decades — new residential belts, Aerocity, Eco City, and New Chandigarh-adjacent development — sector numbers extended well past 100. This is a historical/administrative continuity rather than a strict chronological development order — a higher sector number does not automatically mean newer or less developed; some higher-numbered sectors (like the 100s tied to Aerocity and Eco City) are among GMADA’s most actively marketed zones.

Section 03Road Network & Hierarchy

The same road hierarchy applies across every GMADA sector, per official Local Planning Area drawings:

PR7 specifically is GMADA’s own regional road designation running through the Aerocity/Aerotropolis corridor — distinct from National Highway or State Highway numbering. For the full corridor detail, see our dedicated Aerotropolis Expansion Map.

Section 04Land Use Within a Sector

Within any given sector, land is further zoned by GMADA’s Zoning Plan into specific uses — the same category framework used across GMADA’s Local Planning Area master plans:

Section 05Sector Index — 61 to 123

The table below covers every sector from 61 to 123. Where we found a specific, citable official notice or reliably documented fact tied to that exact sector, it’s noted. Where we did not, we say so plainly rather than guessing — treat those as “confirm directly with GMADA” rather than an information gap on our part.

Section 06Special Projects & Which Sectors They’re Near

For project-specific sector mapping (which exact sectors sit within Aerocity, Aerotropolis, or Eco City boundaries), our dedicated guides linked above go deeper than a general sector index can — they’re built specifically around those project boundaries rather than the full 61–123 numbering range.

Section 08Legal Information

• GMADA Approvals — Building plans and colony licences are approved against the sector’s Zoning Plan and Layout Plan
• FAR — Floor Area Ratio is set per zone/category within the sector, not uniformly across the whole sector
• Road Widening — Always check whether your plot’s frontage falls inside a planned road-widening reserve before assuming current frontage is permanent
• Green Belts — Protected, non-buildable, but adjacency can carry a resale premium
• CLU Implications — Agricultural pockets within or adjoining a sector require a formal Change of Land Use before non-agricultural construction
• Registry & Mutation — Registration transfers legal title; mutation separately updates revenue records — both are required, not just one
• Collector Rates — Vary by sector; Mohali’s rates were revised upward in October 2025 (residential +20-22%, industrial +30%, per public reporting) — confirm current rates before transacting
• PAPRA — Punjab Apartment and Property Regulation Act governs colony licensing and promoter obligations alongside RERA
• Punjab RERA — Any project selling under-construction units must be RERA-registered; verify on rera-punjab.gov.in before booking

Section 09Buyer Verification Guide

1. Confirm the exact sector and plot number against GMADA’s current Zoning Plan for that sector
2. Check the plot’s specific land-use category — don’t assume based on neighbouring plots
3. Verify road width along your plot’s frontage against the road hierarchy table above
4. Confirm ownership via Fard Jamabandi and check for encumbrances
5. Cross-check the Master Plan designation for the broader area, not just the sector layout
6. Ask specifically about any pending road-widening or land-acquisition notices affecting the sector
7. Confirm the colony/layout carries a valid GMADA licence number if it’s a private colony within or adjoining the sector
