Does the land for building compensation for Three Gorges immigrants belong to the category of homestead?

It does not belong to the homestead, but should belong to the state-owned construction land.

According to the Supplementary Notice of Chongqing Municipal People's Government on Relevant Issues Concerning the Implementation of Regulations on Land Requisition Compensation and Resettlement for Large and Medium-sized Water Conservancy and Hydropower Projects (Yufufa [2008] 128),

Fourth, it is stated in the resettlement.

Outside the urban planning area, if the rural immigrant houses are resettled by self-built houses, the houses and ancillary buildings owned by the immigrant individuals will be compensated by 50% in accordance with the compensation standards for land acquisition and demolition formulated by the people's governments of the districts and counties (autonomous counties). Rural immigrants should go through the formalities of construction land in accordance with the relevant provisions, and be exempted from various taxes and fees.

It should be state-owned construction land, provided that all formalities are handled, then you can get the land certificate, handle the planning (building) certificate, build a house, and finally handle the real estate license. The general process is like this, I hope it will help you.
