Synopsis

The Tamil Nadu government has revamped property valuation rules to enhance transparency and align with market realities. A key change is the formal definition of 'composite value' which now includes both the built-up area and undivided land share of a flat's resolving past ambiguity in multi-storey building valuations. Valuation committees can now revise guideline values year-round, instead of only in October. New rules also factor in property quality, location, road access, and amenities under the Tamil Nadu Apartment Ownership Act, 2022. District registrars have been instructed to implement the changes immediately, with updated guideline values to be published online shortly.

The Tamil Nadu government has implemented a significant overhaul of its property valuation norms, with the aim of making property transactions more transparent, fair, and aligned with current market realities. This initiative is expected to directly impact how stamp duty is calculated and how guideline values are assessed across the state, particularly in high-demand zones like Chennai and Coimbatore.


As part of the amendment to the Tamil Nadu Stamp Rules, 1968, the term 'composite value' has now been formally defined. This composite value includes both the built-up area of an apartment and the undivided share (UDS) of land associated with the unit. Until now, there had been ambiguity around how to assess the full value of flats, particularly in multi-storey buildings, which often led to under-valuation and unrecorded cash transactions.

Another major update empowers the valuation committees which include district registrars and valuation officers-to revise guideline values at any point throughout the year. Previously, changes were typically implemented only in October, restricting timely updates in response to fluctuating market conditions. With this flexibility, guideline values can now reflect current property rates more accurately.

The revised rulebook also lays down clear parameters for how flats should be valued. These include construction quality, location of the property, road width, access to public transport, proximity to commercial areas, and the availability of modern amenities such as elevators, parking spaces, and recreational facilities. These criteria are now mandated to be considered under the purview of the Tamil Nadu Apartment Ownership Act, 2022.

Officials within the registration department have confirmed that district-level registrars and sub-registrars have been directed to adopt the new guidelines with immediate effect. Online property registration systems are also being updated to reflect these changes. New guideline values recalculated with these expanded parameters-are expected to be published soon on official government portals.
