The legal process of changing a land parcel's classification from agricultural to non-agricultural (residential, commercial, or industrial) use.
Agricultural land in India cannot be used for non-agricultural purposes — residential, commercial, or industrial — without formal conversion. Also called 'NA conversion' or 'land reclassification,' this process is governed by state-specific laws. In Tamil Nadu, it is regulated by the Tamil Nadu Land Utilisation Order. The conversion changes the land's classification in revenue records from agricultural (wet/dry/garden/manavari) to non-agricultural, allowing development.
The landowner applies to the District Collector through the Taluk office, submitting the Patta, Chitta, FMB, property tax receipts, and required NOCs. The Revenue Inspector conducts a site inspection to verify the land is suitable for conversion. The Collector issues a conversion order if the application meets all criteria. Upon approval, the Chitta is updated to reflect the new non-agricultural classification, and the landowner can proceed with development or sale for non-agricultural purposes.
The conversion process can take 3 to 12 months depending on the district and complexity. Not all land is eligible for conversion — wetland (nanjai), tank-fed land, and land near water bodies face stricter restrictions or outright prohibition. Purchasing unconverted agricultural land at a lower price carries conversion risk — the conversion may be denied, delayed, or subjected to conditions that reduce the land's development value. Conversion before purchase is the safer approach for the buyer.
