The Real Estate (regulation and development), Act, 2016 (RERA) for the first time clearly defines that parking will be part of the common area. ... “What this means is that under RERA, a developer can sell a garage but not a parking since it is part of the apartment and a common area.
It also defines a garage to mean a place within a project having a roof and walls on three sides for parking any vehicle.
The garage is now part of the floor space index (FSI) or floor area ratio (FAR)
Earlier, developers would sell an apartment based on the super area due to which common areas and parking areas were never specified separately in the sale deed. “The statute now demands that the builder sells the unit basis the carpet areas and therefore the need to specify the common areas, that include the parking areas, separately,
State authorities generally approve the number of apartments in a project on the basis of the number of parking spaces offered by the developer as it is now mandatory to offer parking space under the law. Bylaws define the ratio of parking versus the apartment size. Usually, one parking is compulsory for a 3BHK apartment and 2 parking for a 4BHK unit. A parking space under bylaws is defined as equivalent car space or ECS. The total area by definition should be approximately 2.5 m X 4.5 m.
This being the latest rule on the subject, you may fight against this continuing menace by dragging them to the consumer forum seeking relief and remedy as per law.
