Tirupati Air Funnel Zones: Building Height Restrictions

The airport at Renigunta operates off a single instrument runway (designated 08/26), extended in February 2025 to 3,810 m, with a full instrument landing system. This means the airport is classified as an IFR airport, extending the mandatory NOC radius to 56 km from the ARP. Most buyers only know about the 20 km rule. Sellers near Renigunta, Korramenigunta, and Anjimedu rarely volunteer the full picture.

The table below shows the key Obstacle Limitation Surface (OLS) zones and their height implications for construction:

The single greatest trap in this market: the funnel zone. Along the 08/26 runway axis (roughly east-west), plots that appear to be comfortably away from the terminal building may sit directly in the approach or takeoff funnel. In this funnel, the permitted height equals 2% of the distance from the runway edge. A plot 500 m from the runway end is capped at just 10 m above ground level. That is a ground-plus-one-story building. TUDA approval on a layout does not override this. A building plan can pass through TUDA and still fail at AAI's NOCAS. The project gets denied an occupancy certificate, and the buyer inherits the violation.

The AAI has published a color-coded zoning map (CCZM) specifically for Tirupati Airport, available on the NOCAS portal. Use survey-grade GPS coordinates and the CCZM before committing to any plot within 15 km of the Renigunta runway strip.

The airport-adjacent belt running from Renigunta through Korramenigunta toward Anjimedu holds the strongest short-term growth signal in Tirupati, driven by the Electronics Manufacturing Cluster, the IIT and IISER campuses at Yerpedu, and the expanded runway now handling wide-body aircraft. But this exact belt sits closest to the funnel zone, and speculative plots here are being marketed without disclosing the height ceiling.

The table below maps the key corridors by their approximate OLS position and real development risk:

The most misunderstood corridor is the Anjimedu-Renigunta stretch. Builders are marketing plots here as "5 minutes from airport" investment opportunities. What they omit: plots in the approach funnel may legally support only low-rise construction. Banks have begun refusing loans on projects without AAI height clearance, so buyers who purchase without an NOCAS check can find themselves holding land that cannot be financed for development. Before you sign a sale agreement for any plot within 10 km of Renigunta, request the seller's NOCAS application reference or commission your own licensed surveyor's site elevation certificate.
