- The guideline value of property includes both land and building components.
- TNREGINET allows you to check the guideline value by street name or plot number.
Using the official TNREGINET guideline value ensures that you do not underreport property value, which can lead to legal penalties.

By combining EC verification with the building valuation, you can ensure a safe and legal property transaction.
Tips for Accurate Building Valuation in Tamil Nadu
- Use Official Portal Only – Third-party websites may provide inaccurate values.
- Check Street Name Carefully – Guideline value by street name is essential for correct computation.
- Consider Property Type – Commercial and residential buildings have different valuation rates.
- Use TNREGINET Building Value Calculator – Saves time and reduces errors.
- Keep EC and Patta Ready – These documents support your valuation in case of discrepancies.
How Building Value Differs from Land Guideline?
Many people confuse building value with land guideline value, but they are distinct concepts:
- Land Guideline Value: This is the minimum value fixed by the Tamil Nadu government for land in different areas. It is used as a reference for property registration and stamp duty calculations.
- Building Value: This is the value of the constructed property (house, commercial building, or flat) based on construction type, age, floor area, and amenities.
In simple terms, land guideline value tells you how much your land is worth, while building value determines how much your building adds to the total property value.
Knowing the difference is essential because stamp duty and registration charges depend on the combined value of land and building.
