Car share means a vehicle rental program designed for people to rent vehicles for short periods of time, such as a few hours, pay only for their usage, and access the car at any hour, not just  during business hours. The vehicles may be commercially or personally owned. Commercial car share companies generally offer a fleet of vehicles which may be picked up and returned to a designated parking spot, or are picked up and returned to non-designated parking spots. Personal vehicle sharing (peer-to-peer car sharing) allows private car owners to make their vehicles available for rental.

Some car share companies operating in Los Angeles include, but are not limited to: BlueLA, Zipcar, Ryde, Waive, Getaround, Transfr, PiTcarz, Maeve, Turo, Envoy, and  Animo. For the purposes of determining the applicability of this parking exemption, pick-up and drop-off locations are provided by the ADU applicant and verified online. If LADBS staff has  questions on information an applicant supplies to demonstrate a car share program or location, they should consult with the Department of Transportation.
