Layout approved by BIAAPA, BMRDA or DTCP. Not the panchayat.
Confirm which authority actually approved the layout — BIAAPA (the airport-area planning body) in the airport belt, BMRDA (the Bengaluru region planning body) in the outer metropolitan ring, or DTCP (the state town planning department) in taluk areas like outer Devanahalli and Chikkaballapur. A gram panchayat has no power to approve a layout at all. Get the approval number in writing and check it with the authority itself.
DC conversion order for this exact plot (farm land to house land)
Ask for the DC conversion order — the document converting land from agricultural to residential use — separately from the layout approval. A layout can be approved while the specific plot within it is still unconverted.
A-khata (now e-khata), so the bank will give a loan
A-khata (now issued as e-khata, the digital record) means banks will finance it and resale is straightforward. B-khata, or a plain revenue or panchayat khata, means limited or no financing and a harder resale. Converting B-khata to A-khata now costs 5% of guidance value, up from 2% before 23 August 2026.
Same survey number on all papers
Match the survey number across the mother deed, the RTC extract (land record), the DC conversion order and the sale deed. A mismatch here is one of the most common sources of disputes in this belt.
EC for 15+ years: no loan on the land
Pull an encumbrance certificate (EC) covering at least 15 years. It lists every sale and loan registered on the land. Verify any approval or registration number directly with the issuing authority — not just the number printed on a brochure or hoarding, especially in the Bagalur, Shettigere and Chikkaballapur pockets.
Master plan says residential, not green belt
Ask what land use the authority's master plan shows for this survey number. It should say residential. Land marked agricultural, green belt or industrial (the KIADB aerospace park is industrial land) is not meant for houses, whatever the brochure says.
A built road, as wide as the plan shows
Visit the site in person. Roads, drainage, stormwater lines and utility connections shown on a layout plan aren't always built out on the ground in a still-developing pocket, particularly beyond Doddaballapur and around Chikkaballapur. Check the road to your plot is a public road of the width shown on the approved plan, not a path across someone's farm.
Don’t pay extra for “planned” roads or metro
Price in infrastructure that's tendered or under construction, and be wary of paying extra for anything still described as "planned" or "proposed" — the Peripheral Ring Road took almost two decades to reach a construction contract.
