godown of my house

Hi Swati!

If you live in a residential area and it is a residential property, commercial activity is illegal. They are only meant to be done in commercial areas because of the nuisance. 

The godown could only be legal is given permission by the concerned Municipal Corporation (MC). 

In order to shut down the godown, you may file an application under RTI Act, seeking information whether the second floor poeple are carrying out activities upon permission from MC or otherwise. Then accordingly, its upto the MC to take action against them. 

If the MC does not take any action, you can file a writ petition under Article 226 of the Constitution of India for violation of your fundamental rights. Considering the facts of their case, the court of your jurisdiction may pass any appropriate order against your upstairs neighbour.

No one will live in your house. It is your property, whether bought or rented (as per rent agreement).
