The change is significant for property owners registering houses, buildings, apartments and properties with structures, as the valuation process now differs depending on the value of the building.

What happens when the building value is below ₹1 crore?

As per the revised procedure,

For eligible buildings valued below ₹1 crore ➡ The property owners can proceed without waiting for a physical field inspection, subject to the prescribed conditions.

The applicable stamp duty and registration charges can be calculated based on the higher of the self-certified building value or the value determined using the applicable Public Works Department (PWD) schedule.

The applicant must provide the required undertaking and agree to pay the applicable charges based on the value adopted under the rules.

This approach is intended to reduce delays caused by waiting for physical verification of the building.

Example:
Suppose the owner self-certifies the building value at ₹80 lakh, but the value calculated using the applicable PWD schedule rate is ₹90 lakh. Since the rules consider the higher value, the building value for registration would be taken as ₹90 lakh.

Similarly, if the self-certified value is ₹95 lakh and the PWD-based value is ₹85 lakh, the ₹95 lakh value would be considered.

What changes above ₹1 crore?

The key change comes when the building value exceeds ₹1 crore.

For buildings valued above ₹1 crore and below ₹5 crore, an assessment report from an authorised building valuer is required. Reports on the revised procedure identify a ¹Certified Chartered Engineer/approved building valuer as the professional route for this assessment.

The valuation is then compared with the applicable government-prescribed valuation, and the higher value is taken for calculating the applicable charges.

In simple terms:

Building value below ₹1 crore → self-certification/PWD-based valuation route may apply

Building value above ₹1 crore → authorised valuer/Certified Chartered Engineer valuation becomes relevant

Is the ₹1 crore threshold for the entire property?

This is an important distinction for property buyers and sellers.

The ₹1 crore threshold discussed in the revised procedure relates to the building valuation. It should not automatically be interpreted as meaning that every property whose combined land-and-building value exceeds ₹1 crore requires a Chartered Engineer valuation.

For example, consider a property with:

• Land value: ₹1.50 crore
• Building value: ₹40 lakh

The total property value is ₹1.90 crore, but the building itself is below the ₹1 crore threshold.

On the other hand:

• Land value: ₹50 lakh
• Building value: ₹1.20 crore

Here, the building itself crosses the ₹1 crore threshold and the authorised valuation requirement becomes relevant.

Therefore, land value and building value should not be treated as the same component for understanding this rule.

What about buildings above ₹5 crore?

The revised framework also provides a separate treatment :

For buildings valued above ₹5 crore → more detailed valuation/field inspection procedures apply.

The broader objective is to create different valuation routes depending on the value of the building, instead of subjecting every registration to the same physical inspection process.

Why Building Valuation Matters During Registration

Earlier, building valuation during registration was generally based on prescribed PWD rates, with physical inspection and official valuation required for certain higher-value or special-type buildings. Factors such as the building’s type, size, age, construction and additional installations could be considered in the assessment. The revised approach now introduces different valuation procedures based on the value of the building, with professional valuation becoming relevant for higher-value buildings..

What this means for property owners

For property owners dealing with a building valued above ₹1 crore, the practical takeaway is to check the building valuation requirement before presenting the document for registration and ensure that the required authorised valuer/Certified Chartered Engineer report is available where applicable.

Expert Support from Verified Real Estate

Verified Real Estate (VRE) can assist property owners and developers in navigating the building valuation and approval process, including coordinating the required online submissions and documentation. Where a field inspection is required, the VRE team can also help ensure that the owner or developer is properly prepared with the necessary documents, building details and supporting information, helping the process move forward smoothly and efficiently.

The bigger picture

The move is part of a broader effort to make property registration more streamlined while ensuring that the value adopted for stamp duty and registration purposes is properly supported.

For buyers and sellers, however, one point remains critical: ₹1 crore is not simply a blanket threshold for the total market value of every property. The building component and the applicable valuation method need to be examined separately.

As the revised procedures are implemented, property owners should check the latest instructions applicable at the concerned Sub-Registrar Office before proceeding with a high-value registration.

Tamil Nadu is set to assign market guideline values to every land survey number across the State by the end of June 2026, marking an important update in the State’s land registration and property valuation system.

The direction was issued by Tamil Nadu Commercial Taxes and Registration Minister T. Logesh Tamilselvan during the first performance review meeting of senior Registration Department officials.

According to reports, the Minister instructed officials to ensure that guideline values for all land survey numbers in Tamil Nadu are ready by the end of June. He also directed officials to improve public service at registration offices, return registered documents without unnecessary delay, avoid keeping documents pending for avoidable reasons, and complete scrutiny of documents, including building approval-related documents, faster.

This announcement is important because guideline value directly affects property registration, stamp duty, registration charges, land valuation, and the way buyers and sellers calculate the cost of a property transaction.

How Guideline Value Is Currently Assigned

At present, guideline value in Tamil Nadu is largely assigned based on the Sub-Registrar Office jurisdiction, registration village, street name or locality, and property classification such as residential, commercial, agricultural or industrial use. In many urban areas, buyers usually search guideline value by selecting the zone, SRO, village and street name.

Why This Guideline Value Review Is Much Needed Now

1. To Assign Values for Every Survey Number

The main aim of the 2026 review is to ensure that every land survey number in Tamil Nadu has a clear guideline value. This will help buyers, sellers and registration officials identify the correct value for each land parcel without confusion.

2. To Fill Valuation Gaps

For rural lands, agricultural lands and some subdivided properties, survey-number-based values may be available, but they may not be uniformly mapped for every land parcel. This review is expected to fill those gaps and make the registration process smoother.

3. To Bring Uniformity in Property Valuation

The government is also trying to bring more uniformity and transparency in land valuation. When similar properties are valued differently without a clear basis, it can create disputes and delays. A survey-number-wise valuation system can help bring more consistency across different areas and Sub-Registrar Offices.

4. To Reflect Current Market Conditions

Land values have changed in many parts of Tamil Nadu due to urban growth, road projects, infrastructure development and new layouts. When there is a wide gap between the market price and the official guideline value, it can affect stamp duty collection and encourage undervaluation in property documents. So, Updating guideline values can help the official value reflect the current property scenario better.

5. To Include Apartment and Built-Up Property Valuation

The review is also relevant for apartments, villas and row houses, where valuation includes both land share and constructed area. Including composite value for such properties can make valuation more suitable for modern housing projects.

6. To Reduce Registration Confusion

Clearer guideline values can reduce unnecessary doubts during registration. This may help avoid delays, document pendency and repeated follow-up at the Sub-Registrar Office.

Earlier Guideline Value 2023 Revision was Dropped

Tamil Nadu’s earlier guideline value revision in 2023, faced legal scrutiny because the required procedure was not properly followed. The Court noted that the 2023 revision was made without steps such as obtaining reports from a sub-committee or experts, fixing values through the valuation committee, and calling for public objections. The Court therefore directed the State to follow the 2017 guideline values until new guidelines were framed in the manner known to law.

This makes the present review more important. A proper guideline value revision must follow the statutory process, involve the required valuation authorities, and allow the system to be legally sustainable. This is important because guideline value directly affects stamp duty, registration charges and the cost of property transactions for the public.

Conclusion

Tamil Nadu’s move to assign guideline values for every land survey number is an important step towards making property valuation more clear, uniform and transparent. The government is now trying to ensure that every survey number has a clear market guideline value, so that valuation does not depend only on broad locality or street-based references.

For buyers and sellers, it can reduce confusion during registration and give a better idea of the minimum value on which stamp duty and registration charges may be calculated.
