Discrmination between shop owner and flat owner by society.

Hi , I m parmar owner of a shop in co - housing society. I have rented that shop to a tenant , he is doing a business of restaurant . So, under rule of resturant under society should keep their cylinder box outside of the shop which take just 2 ft sticking to shop. But the society asked us to keep that box inside the shop reasoning for the by laws or else penalty is been charged. But the society has some things which I felt that is too illegal those are 1) The flat owner containing open terrace have built a room of that terrace ..which I think thats illegal . Constructing with bricks and cement on open terrace is fully legal. 2) The passage outside of flat is too small though the flat owner/tenant keep their shoe racks as well as plants outside the flat in the place of passage, under fire emergency the passage is most important space for saving life but rules are just ruined in this society. I wrote a letter to the society asking for the same but they excuse to take any action against this said that the flat owner can do whatever they want inside the flat and terrace area inside those flats.
