Is it illegal for the owner to build a fish tank on the balcony?

As long as it does not belong to illegal or unauthorized construction, I sealed a balcony, which has been completed on the premise that the property has no objection, and the poor property management should be demolished. You don't have to pay the property fee. Don't you have to tear it down anyway? You just let the urban management dismantle it first, and you don't have to pay any fees before solving it. In addition, as long as there is an unrealistic property management contract in the middle, you don't have to pay the property fee, because it is legal for you. Accelerate the establishment of the owners' committee, and everyone can bid by themselves-find a property company to manage the community. And have the right to dismiss the property company.
