Legal Checks for TDR and FSI Transfer in Bangalore

What Legal Checks Are Needed When a Bangalore Developer Retained Extra FSI Through a Separate FSI Transfer Agreement?

By the Property Law Team | Legal Brigade | Bar Council of Karnataka

When a Bangalore apartment developer obtained Transferable Development Rights – certificates issued by BBMP for land surrendered for road widening, heritage conservation or other public purposes – or used extra Floor Space Index incentives available under the BDA’s FSI bonus provisions for green building certification, affordable housing or other qualifying criteria and utilised or transferred these additional FSI entitlements for a different project without disclosing the arrangement to the allottees of the project on whose land the TDR was generated or the extra FSI was earned, the developer may have appropriated a development benefit that arose from the allottees’ collective land without their knowledge or consent.

What Are TDRs and FSI Bonuses and How Do They Arise?

Transferable Development Rights are certificates issued by BBMP or the BDA when a plot owner surrenders land for a public purpose – such as road widening, conservation of a heritage structure or provision of affordable housing. The TDR certificate gives the owner the right to construct additional built-up area on a different plot – or to transfer the TDR to another developer who can use it. The TDR compensates the surrendered land’s owner for the loss of development potential by allowing development rights to be used elsewhere.

FSI bonuses are additional FAR allowances granted by BBMP or the BDA for specific public-interest developments: a green building certification earns additional FAR; constructing affordable housing within a larger project earns additional FAR for the market-rate component; providing public parking earns additional FAR. These bonuses are specific to the project that earns them and attach to the project’s land. When a developer earned TDRs or FSI bonuses from a project’s land or development and then used or transferred those rights without the allottees’ knowledge, the allottees collectively lost the benefit of a development right that arose from their land.

How Do I Check FSI and TDR Usage Before Buying?

Step 1: Review the BBMP building plan sanction for the specific project – confirming the sanctioned FAR and whether any TDR loading or FSI bonus was included in the sanction.

Step 2: Confirm the RERA registration discloses the total FAR used, any TDR loading and any FSI bonus – and the basis for each.

Step 3: If TDRs were used, confirm they were validly generated and transferred through BBMP’s TDR certificate register – checking the TDR’s origin and validity.

Step 4: If an FSI bonus was claimed (green building, affordable housing), confirm the qualifying condition was actually met – that the green building certificate exists or the affordable housing component was built and handed over.

Step 5: Have a property lawyer assess the FSI and TDR usage in the building plan sanction and advise on any undisclosed development benefit that the developer may have appropriated.

Q1. What is a Transferable Development Right and how does it arise in Bangalore?

A Transferable Development Right is a certificate issued by BBMP or the BDA when a plot owner surrenders land for a public purpose. In Bangalore, TDRs arise most commonly from road widening – when BBMP requires land from a private plot for a road widening project, the plot owner receives TDR certificates allowing them to construct additional built-up area on a different plot or to transfer the certificate to another developer. The TDR compensates for the lost development potential of the surrendered land.

Q2. Can the developer use TDRs generated by a project’s plot for a different project?

TDRs are transferable – they can be used on a different plot from the one that generated them. The question of whether the developer appropriated the allottees’ TDRs is complex: the TDRs arise from the plot’s land, which the developer holds until the flat sale transfers the UDS to the allottees. If the TDRs were received before the allottees purchased, the developer may have a legitimate claim to them. If the TDRs arose from land that had already been transferred as UDS to the allottees, the allottees have a stronger claim.

Q3. What is an FSI bonus and how does it work in BBMP’s building regulations?

An FSI bonus is an additional FAR allowance granted by BBMP for specific qualifying development types: green building certification earns additional FAR; constructing affordable housing within a project earns additional FAR for the market-rate component; providing public parking earns additional FAR. The bonus allows the developer to construct more built-up area than the base FAR would permit. The bonus must be earned through the qualifying development – a developer who claims an FSI bonus without actually constructing the qualifying component has made a fraudulent claim.

Q4. How does TDR usage appear in the BBMP building plan sanction?

The BBMP building plan sanction for a project that uses TDRs specifies the base FAR from the plot’s own development potential and the TDR loading – the additional FAR from the transferred TDR certificates. The total sanctioned FAR is the sum of both. The TDR certificates themselves are recorded in BBMP’s TDR register. A buyer can check the building plan sanction to confirm the total FAR used and whether any TDR loading was included.

Q5. Does RERA require disclosure of TDR usage and FSI bonuses?

Yes – the RERA registration for a project requires disclosure of the total built-up area, the FAR used and the basis for the FAR calculation. A project that uses TDRs or FSI bonuses must disclose these in the RERA registration. An undisclosed TDR or FSI bonus use is a RERA disclosure violation that the allottees can raise as a RERA complaint.

Q6. What if the developer used an FSI bonus for green building but the project was not certified?

A developer who claimed an FSI bonus for green building certification but did not obtain the certification has made a false claim to BBMP. The extra FAR in the building plan sanction was obtained through a false claim – and BBMP can revoke the excess FAR and require the demolition of the floors built under the false bonus. The allottees in those floors face the demolition risk from the false FSI bonus.

Q7. How does a buyer confirm the TDR’s validity?

BBMP maintains a TDR register that records each TDR certificate’s issue date, the issuing authority, the surrendered land’s details and the certificate’s usage status. A buyer or their lawyer can check the TDR register to confirm the specific TDR certificates used in the building plan sanction are validly issued, not cancelled and properly applied. BBMP’s TDR records are publicly accessible.

Q8. Can the association claim compensation if the developer appropriated TDRs from the project’s land?

If the developer appropriated TDRs that arose from land that had been transferred as UDS to the allottees – without the allottees’ knowledge or consent – the association may have a claim for the value of the appropriated TDRs. This would require a legal assessment of whether the TDRs arose before or after the UDS transfer and whether the developer had a right to retain and transfer the TDRs under the sale agreements.

Q9. Is FSI loading from TDRs visible in the EC?

TDR certificate usage is primarily documented in the BBMP building plan sanction, not in the sub-registrar’s EC. The TDR certificates themselves are registered documents under BBMP’s system – not the sub-registrar’s system. The EC review will not reveal TDR usage. The building plan sanction and the BBMP TDR register are the specific documents for TDR verification.

Q10. How does Legal Brigade check FSI and TDR usage during property verification?

Legal Brigade obtains the BBMP building plan sanction and identifies the total FAR used, the base FAR from the plot and any TDR or FSI bonus loading. Legal Brigade checks the BBMP TDR register for the validity of any TDR certificates used and confirms the FSI bonus qualifying conditions were actually met (green building certificate, affordable housing construction). Where an undisclosed appropriation or a false bonus claim is identified, Legal Brigade advises on the allottees’ RERA complaint and the enforcement risk.

Buying a flat in a Bangalore project where the building appears taller than the plot area would normally permit? The TDR certificate validity check and the FSI bonus qualifying condition confirmation protect you from extra floors built on a false or appropriated development right.
