TDR and FSI: potential is not permission

What is the difference between FSI and TDR?

FSI expresses the relationship used under applicable planning regulations to assess development against plot area. TDR concerns transferable development rights subject to their governing instruments and rules. Neither a theoretical calculation nor possession of a certificate alone establishes permission for a particular scheme. The planning jurisdiction, date, land inputs and conditions must be identified.

Reconcile gross and net plot area, deductions, existing consumption and proposed components. Do not treat FSI area as identical to saleable carpet area or investment value.

What should a technical and legal review verify?

Check the applicable regulations, sanctioned plans, rights certificate, transfers, utilisation balance and receiving-site eligibility. Access, reservations, restrictions and approval conditions can affect loading. Every material assumption should be traceable to an official record or clearly labelled as pending; a neighbouring project’s calculation does not establish the entitlement of the subject parcel.

The output should separate verified facts, conditional scenarios and approvals still needed. Tax, valuation and purchase of rights are separate scopes. No universal FSI ratio is published here because the governing rules vary.
