RERA act Tamilnadu has been notified. In 2014 my builder handed over my flat and till today has not completed the external facilities of lift, swimming pool and intercom facility. In his web site he shows that our apartment project has been completed. We have formed the association and taking care of monthly maintenance as 18 flats were handed over out of total 22. The builder does not respond to the association's request to provide lift swimming pool and intercom facility as per signed agreement. Can we complain to the RERA authorities?
