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.

The aim of LADBS Code Enforcement is to preserve and enhance the safety, appearance and economic stability of our community through the diligent enforcement of applicable ordinances and land use regulations. It maintains Los Angeles Municipal Codes (LAMC) by issuing an Order to Comply (OTC) to the property owner and any other person in control of a property who violates or causes or permits another person to violate any provision or requirement of the LAMC.
The OTC is essentially a warning letter with a time frame for voluntary compliance. The OTC describes the violation(s), instructions to remedy the violation(s) and warnings of possible penalty fees and criminal prosecution. Violation of the LAMC is a misdemeanor and code enforcement cases must therefore be prepared for the possibility of being resolved in Los Angeles Superior Court.
