Airport Height Limits in Chennai: What They Mean for Homes Near Meenambakkam and Tambaram

Quick links: How the rules work · Areas reported as most restricted · What to check · FAQs · Sources

If you own or plan to buy property around Chennai airport, how tall a building can be is not decided by planning rules alone. A height limit set by the Airports Authority of India (AAI) applies to land around airports, and defence airfields add their own restrictions. Here's how it works, based on official guidelines and reported cases.

This is general information, not legal or technical advice. Always check the official AAI map and NOC requirements for the exact site.

How the rules work

• The Ministry of Civil Aviation lists the Height Restrictions for Safeguarding of Aircraft Operations Rules, 2015 among its notifications.
• AAI's guidelines say that, under Rule 6 of Ministry of Civil Aviation notification G.S.R. 751(E), AAI issues Colour Coded Zoning Maps (CCZM) for areas within about 20 km of an aerodrome.
• Each grid square on the map has a Permissible Top Elevation (PTE), measured above mean sea level.
• Permissible building height above ground = PTE − the site's ground elevation.
• If the site's grid is red, or the proposed building is taller than the PTE, or the site is in an approach, take-off or transitional area, an AAI No Objection Certificate (NOC) is required through the NOCAS portal before the local body can approve the building.
• If the building is at or below the PTE (and the grid doesn't require a NOC), the plan goes to the local body for approval without an AAI height NOC.
• On 18 June 2025 the Ministry of Civil Aviation released the draft Aircraft (Demolition of Obstructions Caused by Buildings and Trees, etc.) Rules, 2025 under the Bharatiya Vayuyan Adhiniyam, 2024. The draft lets the aerodrome officer-in-charge serve notices on owners of structures that break notified height limits, and proposes to replace the 1994 rules (SCC Online).

Areas reported as most restricted

Verified.RealEstate, a Chennai property platform, has published the following lists. They are a starting point only; the official map decides each site.

The same source reports that construction close to a defence base perimeter may need a separate Ministry of Defence NOC.

A reported case

In January 2023, airport officials issued notices asking owners of 146 houses in Kolapakkam (Kancheepuram district), near Chennai airport, to reduce their height, saying the buildings obstructed aircraft landing. The notice said each house should be reduced to 5 metres from 9 metres, depending on location. The panchayat council passed a resolution opposing the demand, and residents asked about compensation (DT Next).

On 24 August 2026 the state government announced it would drop the Parandur airport project and identify another site, and said a fifth terminal is planned at the existing Meenambakkam airport (The Week). Later developments on the sites under study are tracked in our article on the Parandur cancellation.

What to check before you buy or build

• Find the plot's coordinates and look up its grid and PTE on the CCZM map on the NOCAS portal (nocas2.aai.aero).
• Get the site's ground elevation surveyed, and work out the permissible height.
• For apartments, ask the builder for the AAI NOC (if required) and check that the approved height matches it.
• Near Tambaram Air Force Station, ask whether a defence NOC applies.
• Check that the building plan approval was issued after any required NOC.
