3 . We are unable to agree. Appendix XVIII which is part of Rule 33 of the Rules deals with Zoning Regulations and it lists out activities that could be permitted in a residential use zone. That will not confer the right on the petitioner to convert a residential building into a non-residential use. If the petitioner wants to do so, the petitioner will have to apply under Sub Rule 8 of Rule 6 of the Tamil Nadu Combined Development and Building Rules, 2019, seeking conversion of the user of the building. It will therefore be open to the petitioner to apply to the Competent Authority under Sub Rule 8 of Rule 6 of the Tamil Nadu Combined Development and Building Rules, 2019, seeking conversion of the building into a Commercial Building. We are sure that the Authorities will consider the application in accordance with law. The petitioner shall file the application within a period of two weeks from today and the Authority will pass orders within a period of 8 weeks there from. Till such time, the user of the petitioner shall not be interfered with.
