House construction in Yelahanka

Air Force Station Yelahanka sits beside the town. The Indian Air Force requires its clearance for buildings within five nautical miles (9.26 km) of the airfield, and the station is one of four aerodromes on Bengaluru's colour-coded height map. There is a calendar effect too. For Aero India 2025 the corporation ordered builders within 10 km of the base to lower their cranes and stop crane work from 1 to 14 February. The show comes round every two years, so a Yelahanka build that runs through a February is planned around it.

In October 2024 Yelahanka flooded three times in one month. Doddabommasandra Lake overflowed for the first time in more than 17 years, a compound wall gave way at the Kendriya Vihar apartments, and about 4,000 houses in ten layouts of the Yelahanka zone were affected, with water up to six feet deep in places. Before a house is placed on a Yelahanka plot, its level is checked against the nearest lake, drain and road.

The Central Ground Water Board's 2024 assessment puts Yelahanka taluk at 260% of sustainable groundwater extraction, second only to Bangalore East in the district. Cauvery Stage V was built for the villages added to the city in 2007, several of them in the Yelahanka and Byatarayanapura zones, and connections were still being rolled out in 2025. Ask BWSSB about your street, and design the sump and rainwater harvesting in from the start.

Plans go to the Bengaluru North City Corporation online, with an e-Khata. A site in the Housing Board's New Town should already sit in an approved layout; a revenue site on the edges may carry a B-khata, which has to be converted before a plan is sanctioned. Plots up to 50x80 ft with up to four dwelling units can use the Nambike Nakshe route.
