How to convert agricultural land to non-agricultural (NA) use?

Agricultural land can normally be used only for farming. To build a house, shop, factory or to plot it for sale, you usually need to convert it to non-agricultural (NA) use, also called land use conversion or diversion. The broad process is: apply to the competent revenue authority, often the collector or sub-divisional officer, with documents such as the current land record (7/12, khatauni or RoR), a map or layout, a no-objection where required, and proof of ownership. The authority checks that the land is not under any restriction (for example tribal land, land near defence areas, or land reserved in the town plan), then levies a conversion charge or premium and issues an NA order. After conversion the use is recorded in the revenue record. Important cautions: conversion rules, charges and the deciding authority differ a lot by state, some states have simplified or deemed-conversion systems, and some categories of land cannot be converted at all. Charges depend on location and area and can be significant. Also check the local town or panchayat building rules separately, because NA permission and building permission are two different things. Always confirm the current procedure and charges with your tehsil or collectorate, and take legal advice for anything beyond a simple case. This is general information, not legal advice.
