1. if the promoter has already conveyed his right title and interest in the land and building to the organisation of flat purchasers, then he ceases to have any right in the land and building, except the unsold flats
2. once the land and building are conveyed to the society, any repair work will come under the purview of the society and only the society can carry on such repair work
3. if society is not yet formed but there is an informal committee of flat purchasers and also if the land and building are also not conveyed to society and the management of the same is not handed to the society, then the builder has the right to access for repair work only and not for making any further construction or for installing any mobile tower or hoarding on the rooftop
