What a BDA auction is
The Bengaluru Development Authority (BDA) sells residential and commercial sites across Bengaluru through public e-auctions. Each auction is announced in a numbered notification with a site list, a reserve rate — the floor price — per square metre for every site, and the deposit and payment terms.
This guide follows the process using BDA’s T-08/2026-27 notification of 25 June 2026 as a worked example — 175 sites across 44 areas, from Koramangala to the Arkavathi Layout blocks. Dates and figures change with every notification, so read them off the current one for the sites you are following. — per the BDA English e-auction notification T-08/2026-27 dated 25.06.2026.
Where the bidding happens — online
BDA bidding is fully online, on the Karnataka Public Procurement Portal (KPPP). For T-08, the e-auction opens on 13 July 2026. The sites then go to timed bidding in rounds spread over 28 to 31 July 2026, each running from 11 AM on its start day to 5 PM the next day. The notification assigns every site, by serial number, to its round. — per the BDA English e-auction notification T-08/2026-27 (schedule).
Two rules in the terms are easy to miss: a bid must be more than 10% above the base (reserve) price to count, and a site that draws only a single bidder is rejected. A bid placed in the last moments also adds five minutes of extra time, so a round can run past its printed close — follow the live clock on the portal. The bidding itself happens on KPPP, never on BiddingPulse. — per the BDA English e-auction notification T-08/2026-27 (terms).
The earnest-money deposit (EMD)
The earnest-money deposit (EMD) is the refundable deposit you place to take part. T-08 sets it as a flat ₹4 lakh per site — the same amount whether the site’s reserve works out to about ₹32 lakh or over ₹3.5 crore (totals we work out from the printed per-square-metre rate and area; the notification prints the rate, not a total). That is unlike the percentage-based deposits DDA and Chandigarh use. You express interest by the deadline in the notification and pay the EMD as the portal instructs. — per the BDA English e-auction notification T-08/2026-27.
If you win, the payment clock is tight: you top up to 25% of your final bid, minus the EMD already paid, within 72 hours of BDA’s advice letter (the letter telling the winner the result and the amount due) — the terms say missing that window can forfeit the deposit — and the remaining 75% falls due within 45 days of the allotment letter (the letter formally assigning the site to you). — per the BDA English e-auction notification T-08/2026-27 (clause 18 and payment terms).
The auction timeline
Notification issued — 25 June 2026. E-auction opens on KPPP — 13 July 2026. Last date to express interest — 27 July 2026 at 5 PM IST. Timed bidding rounds — 28 to 31 July 2026, each running from 11 AM to 5 PM the following day, with every site assigned to its round in the notification. — per the BDA English e-auction notification T-08/2026-27 (schedule).
The sites sell as-is — in their current condition, with no fixes from BDA. The terms ask bidders to visit the site, check its road width, and confirm the location on the ground before bidding; treat the map pin in the notification as a rough guide only. After the auction, the 25%-within-72-hours and 75%-within-45-days payment stages above apply. — per the BDA English e-auction notification T-08/2026-27 (terms).
