Hi, There is certain rule set by Supreme Court .The Guidelines provide that a minimum of two percent of the parking spaces serving covered dwelling units be made accessible and located on an accessible route to wheelchair users. Also, if a resident requests an accessible space, additional accessible parking spaces would be necessary if the two percent are already reserved.Builder or society has no right to charge for parking space. however charges can be raised if extra security is being deployed to the reasonable extent and the expenses are accounted for with legal justification.
