1. I am afraid that this may not be a proper and authenticated document to prove that this property coming under Gaothan property.
2. The loan land revenue office will be having the details of entire properties under its jurisdictions, if you dont find any record pertaining to your query, you may visit Collector's office land department from where you can ascertain the details.
3. For this I had given the provisions as well as the latest amendment in this regard in my previous post, for the purpose of repetition I shall reproduce the same once again:
DCR 33(9) Repairs and reconstruction of cessed buildings and Urban Renewal Scheme: For repairs & reconstruction of cessed buildings and Urban Renewal Scheme undertaken by the Maharashtra Housing and Area Development Authority or the Mumbai Housing and area Development Board or Corporation in the Island City, the FSI shall be 4.00 or the FSI required for rehabilitation of existing tenants / occupiers, whichever is more.
Hope this clarifies the issue.
