Moreover, there are some guidelines on laying and replacement of wall finishes. And yes, permit is required for the following types of building works.

1) Replacement of internal wall finishes up to ceiling level.

2) Replacement of existing bathroom/toilet wall finished after first 3 years from the date of completion of the book.


For the situations which are mentioned above, it is compulsory to meet these guidelines:
