Construction without sanction is the most expensive shortcut in Bengaluru: it blocks the occupancy certificate, complicates the property-tax assessment, weakens resale and exposes the building to notices. But sanction is not automatic — the site's Khata, the layout's approval status, road width and setbacks decide whether a plan can be sanctioned at all.
This journey is for individual owners building or extending on their own site. Developers and builders should see the real estate section.
Does this sound like you?
You own a site and want to build a house
The first question is eligibility — A Khata, approved layout, road width. Then drawings, then sanction.
You want to add a floor or extend
Plan alteration or a fresh sanction depending on the extent; the existing sanction and tax record must be in order.
Your site is B Khata or in a revenue layout
Sanction is generally not available; conversion to A Khata (if eligible) comes first. We tell you honestly if it is not.
Your architect has asked for documents you do not have
Khata extract, tax receipts, EC, conversion order, layout approval, survey sketch — we assemble the set.
You built already and now need to regularise or get an OC
Depends on the extent of deviation; we assess what is achievable and what is not.
What usually needs to be done
Eligibility check
Khata status, layout approval, zoning/land use, road width, site dimensions and any pending tax — before you pay for drawings.
Document set
Title deed, Khata certificate and extract, e-Khata, tax-paid receipt, EC, survey sketch, conversion order where applicable, and owner identity.
Application and sanction
Filing through BBMP's online building-plan system with the architect's drawings, fee calculation, response to scrutiny remarks, and follow-up to sanction.
After sanction
Commencement, inspections where required, completion/occupancy certificate, and first property-tax assessment of the new building.
Documents to gather
- Registered title deed and prior deeds
- Khata certificate and extract (A Khata) and e-Khata
- Latest property-tax-paid receipt
- Encumbrance Certificate
- Survey sketch / site plan; layout approval or conversion order
- Architect's drawings prepared to BBMP bye-laws
- Identity proof of all owners; consent where there are co-owners
Send the Khata and a tax receipt. We will tell you whether sanction is realistic before you spend on drawings.
Services in this journey
Frequently asked questions
Can I get plan sanction on a B Khata site?
Generally no. BBMP building plan sanction is tied to A Khata / regular properties in approved layouts. For eligible sites the route is conversion to A Khata first; for others, we tell you plainly that sanction is not available and what the alternatives are.
What decides whether my site is eligible?
Khata status, whether the layout is approved (BDA/BMRDA/BBMP), the land-use zone, road width in front of the site, site dimensions and setbacks under the bye-laws, and whether tax is fully paid. We check each before filing.
How long does BBMP plan approval take?
It varies with the site, the completeness of the file and scrutiny remarks; we give a realistic estimate after the eligibility check rather than a generic number.
