Bhubaneshwar Air Funnel Zones
AAI

Overview
The Bhubaneswar airport height restriction zone covers all land within 20 km of the Aerodrome Reference Point (ARP) of Biju Patnaik International Airport. Every structure in this radius requires a No Objection Certificate (NOC) from the Airports Authority of India before construction begins, under GSR 751(E) notified 30 September 2015. AAI published a color-coded zoning map (CCZM) for Bhubaneswar in June 2016, which defines seven permissible top elevation bands ranging from 80 m AMSL to 190 m AMSL. This page explains what those bands mean for your plot, which localities face the tightest caps, and what the Jagamara enforcement case tells buyers right now.
Illegal Construction Near Biju Patnaik Airport: The Regulatory Red Flags No Broker Will Tell You
Red (innermost)
Permissible Top Elevation (AMSL)
80 m
Implication
NOC from AAI mandatory; near-zero headroom in low-lying areas
Orange
Permissible Top Elevation (AMSL)
90 m
Implication
Strict cap: local body cannot approve above this
Yellow
Permissible Top Elevation (AMSL)
105 m
Implication
Moderate restriction; site elevation determines usable floors
Green
Permissible Top Elevation (AMSL)
115 m
Implication
Most of core city; standard mid-rise possible subject to CCZM check
Blue
Permissible Top Elevation (AMSL)
135 m
Implication
Outer areas: multi-storey feasible pending site elevation
Purple
Permissible Top Elevation (AMSL)
160 m
Implication
Peripheral zone: lower risk but NOC still required within 20 km
Grey (outermost)
Permissible Top Elevation (AMSL)
190 m
Implication
Approaches 20 km radius; height largely unrestricted for typical builds

The critical trap is that heights on the CCZM are in AMSL, not above ground level. A broker quoting floor count without verifying the site's surveyed elevation against the CCZM band is giving you incomplete information. Two adjacent plots in the same locality can sit in different color bands if the topography changes. Verify the grid reference for your exact survey number on the CCZM grid map, also published by AAI for Bhubaneswar.
There is an active enforcement case directly on record for this city. An unauthorized two-story market complex in Jagamara, situated directly under the approach path of flights at Biju Patnaik International Airport, was flagged by airport officials in mid-2025 as a serious obstruction to aircraft operations. The structure was built without the mandatory NOC and, as of the most recent reporting, remained standing because demolition authority rests with the Bhubaneswar Municipal Corporation (BMC) and the Bhubaneswar Development Authority (BDA), not with AAI itself. AAI can flag. It cannot bulldoze. This enforcement gap is the single fact every buyer near the southern approach corridor needs to carry into a site visit.

Research on Bhubaneswar specifically found that building height thresholds in this city remain low and largely unchanging up to 9 km from the airport before jumping sharply. This is unusual: in several comparable cities, the threshold begins rising earlier. Buyers targeting plots within 9 km of the ARP should treat the CCZM as a hard constraint before any negotiation on price or floor count.
The most misunderstood corridor is the southern stretch through Jagamara toward Sundarpada. Proximity to NH-16 and airport connectivity drive demand there, but that same proximity places plots inside or near the approach funnel, where the permitted building height equals 2% of the distance from the runway edge. At 1,000 m from the runway edge, that cap is 20 m above ground. Buyers looking at this corridor for high-density development face a structural ceiling, and no amount of builder reassurance substitutes for the surveyed site coordinates verified against the CCZM grid.
Frequently Asked Questions
What is the height restriction near the Bhubaneswar airport?
All structures within 20 km of Biju Patnaik International Airport ARP are governed by AAI's CCZM, with permissible top elevations ranging from 80 m to 190 m AMSL depending on plot location.
Do I need an NOC from AAI to build near the Bhubaneswar airport?
Yes, under GSR 751(E). If your plot is below the CCZM limit, the local body clears it. If it exceeds the limit, apply directly through NOCAS for an AAI NOC.
How do I check if my plot falls in the Bhubaneswar Airport height restriction zone?
Download the CCZM grid from nocas2.aai.aero, locate your survey number's grid cell, note the permissible top elevation, and then subtract your WGS-84 certified site elevation to get the permitted height above ground.
What is AMSL, and why does it matter for Bhubaneswar plots?
AMSL means Above Mean Sea Level. AAI caps height in AMSL, not floors. Two adjacent plots can have different floor allowances if ground elevations differ. A CPWD, PWD, or Survey of India elevation certificate is mandatory.
What happens if a building is constructed without an AAI NOC near Bhubaneswar airport?
It becomes an illegal obstruction. AAI can flag it to BMC, BDA, and GAD for demolition. The 2025 Jagamara case shows enforcement can be slow, but legal liability stays with builder and buyer.
How long is an AAI NOC valid for a building in Bhubaneswar?
Valid for eight years from issue date. One revalidation is permitted if construction has commenced and the delay is beyond the developer's control. After eight years, a fresh NOC is required; permitted height may differ.
Which localities in Bhubaneswar carry the highest airport height restriction risk?
Pokhariput, Jagamara, and Ghatikia within 5 km of ARP face the tightest constraints. Khandagiri and Chandrasekharpur are moderate. Patia and Phulnakhara beyond 9 km carry lower risk but remain within the 20 km NOC zone.
