We have some plants in the terrace attached to our flat. I was approached by our secretary, asking me to take away all those plants, and that he did not allow anyone else to raise plants, so there was no question of allowing us too. What surprises me is that, only 2 flats in our society have a terrace attached. The secretary said he would not allow to keep such heavy plants on the terrace, pointing to a chajja that he had instructed the owner to remove all the potted plants placed on the chajja. Is a chajja not structurally differnet from a terrace? Can the society stop me from having plants on the attached terrace and on what grounds?
