The area around Kempegowda International Airport (KIA) in Devanahalli has seen enormous property price appreciation driven by IT infrastructure, ITIR proposals, and Aerotropolis development plans. But buying near an international airport comes with a set of legal restrictions that are not immediately obvious and can significantly affect the usability and value of your property.
Restriction 1: Height Restrictions (Air Funnel Zone)
The Airports Authority of India (AAI) mandates height restrictions for all structures within a certain radius of the airport. These restrictions are defined by the Airport Obstacle Limitation Surfaces (OLS). Buildings that exceed the height limit require NOC from AAI.
For Devanahalli, the no-construction height limit varies by distance from the airport. Properties within the Inner Horizontal Surface cannot have structures above a certain height. Apartment projects that did not obtain AAI NOC may face rejection of building plan approvals or post-construction legal challenges.
Restriction 2: Noise Zones
Properties directly under or near flight paths are designated as noise-affected zones. While this does not legally prevent purchase, it affects liveability and the Government of India has guidelines on noise insulation requirements for residential buildings in such zones. Check the noise contour maps for KIA before buying.
Restriction 3: KIADB Land Acquisition
The Karnataka Industrial Areas Development Board (KIADB) has acquired large tracts of land in the Devanahalli region for the ITIR (Information Technology Investment Region) and Aerospace Park. Some land that is still privately held may be under notification for future KIADB acquisition. Sellers of such land may not disclose the acquisition notice. Check for KIADB notifications on the specific survey number before purchasing.
Restriction 4: Agricultural Land Classification
Despite the development activity, many survey numbers in Devanahalli remain classified as agricultural in the Revenue records. The RTC Pahani for such land may still show "agricultural" in Column 7 even if the land is being sold as a plot. DC Conversion must be verified. See: DC Conversion in Karnataka.
Restriction 5: Eco-Sensitive and Nandi Hills Buffer Zones
Parts of the Devanahalli taluk near Nandi Hills fall within eco-sensitive zone buffers designated by the Ministry of Environment, Forest and Climate Change. Construction within these zones is restricted. Check the relevant Ministry notifications for the specific survey number.
What to Verify Before Buying in Devanahalli
- Obtain AAI NOC check for height clearance (ask the developer for proof)
- Check for KIADB acquisition notifications on the survey number
- Verify DC Conversion for agricultural land
- Confirm no eco-sensitive zone restriction
- Check noise zone classification if near approach paths
- Verify RERA registration for apartment projects
- Obtain 30-year EC and check for government acquisition entries in RTC Column 10
