Question 1

What is the Mumbai airport funnel zone and does it affect my plot near Santacruz?

Accepted Answer

Yes. The funnel zone has covered 50% of suburban Mumbai, including Santacruz, Vile Parle, Kurla, and Andheri, dating back to 1928 under earlier aeronautical regulations. The AAI CCZM for Mumbai and Navi Mumbai governs permitted building height across a 20 km radius of CSIA under GSR 751(E), 2015.

Question 2

Do I need an NOC from AAI to build near Mumbai airport?

Accepted Answer

Yes, if your building exceeds the CCZM permitted top elevation for your grid. At 4 km from CSIA, Mumbai airport height restrictions trigger AAI approval for buildings above just 17.87 m, the strictest threshold of any major Indian city. Apply via the NOC Application System (NOCAS) portal before starting construction. Check your plot's CCZM grid colour on the 1acre Premium map (1acre.in/subscribe) before filing an NOC application.

Question 3

How is AMSL height calculated for a plot near Mumbai airport?

Accepted Answer

Subtract your plot's certified ground elevation in meters AMSL from the CCZM Permitted Top Elevation for your grid square. Mumbai airport sits at 14 m AMSL. Even low-lying suburban plots consume the AMSL ceiling quickly. Get elevation certified in World Geodetic System 1984 (WGS-84) datum by a licensed surveyor before filing any NOC application.

Question 4

What is the maximum building height allowed near Chhatrapati Shivaji Maharaj International Airport?

Accepted Answer

At 4 km from CSIA, the threshold is 17.87 m before AAI approval is required. In the approach funnel along runway 09/27, permitted height equals 2% of distance from the runway edge: 1,000 m away allows only 20 m of height. These are the tightest height limits in India's major metros.

Question 5

What is TDR and how does it apply to Mumbai airport funnel zone properties?

Accepted Answer

TDR is the transfer of development rights. Maharashtra's April 2025 DCPR-2034 amendment allows funnel zone property owners in Santacruz, Vile Parle, Kurla, and Ghatkopar to generate TDR equal to unutilised FSI caused by height restrictions, then sell or use it elsewhere. Basic FSI within the funnel zone remains 1.

Question 6

What happens if a building near Mumbai airport violates height restrictions?

Accepted Answer

Violations are enforced under the Aircraft (Demolition of Obstructions) Rules, 1994. AAI demolished its own ATC tower at CSIA in 2014 for penetrating runway 14/32's obstacle limitation surfaces by over 50 m. Courts can mandate demolition of non-compliant floors regardless of construction stage or the investment made.

Question 7

Does Navi Mumbai International Airport create new funnel zone restrictions?

Accepted Answer

Yes. NMIA (runway 08/26, northeast-southwest orientation) opened commercially on 25 December 2025. Its funnel zone covers an estimated 65% of Navi Mumbai, including Ulwe, Chinchpada, Khandeshwar, and Mansarovar. AAI restricted 150 projects near Navi Mumbai to 55 m height during the pre-operational period. Verify your CCZM grid before buying any plot in this area.
