The car parking is a part of the society's common area which cannot be sold. The developer has no right to charge for this space. In 2010, the Supreme Court had held that developers had no right to sell parking to apartment-owners, including stilt parking or garages.

According to the “Apartment Act” in most states, car parking is a part of the society’s common areas. Since the purchase of parking slots has been deemed illegal, the transaction to purchase would become null and void. Once the housing society is registered, it becomes the owner of all the common spaces of the apartment complex including the parking spots.

A builder has to provide a certain number of parking spaces basis the number of units of houses. As per a mandate from the Mumbai High Court, the builder is not allowed to sell parking spaces outside the FSI consumed. This has been confirmed by the Supreme Court of India too.
