VEH §22650: (a) It is unlawful for a peace officer or an unauthorized person to remove an unattended vehicle from a highway to a garage or to any other place, except as provided in this code.

(a) It is unlawful for a peace officer or an unauthorized person to remove an unattended vehicle from a highway to a garage or to any other place, except as provided in this code. (b) Any removal of a vehicle is a seizure under the Fourth Amendment of the Constitution of the United States and Section 13 of Article I of the California Constitution, and shall be reasonable and subject to the limits set forth in Fourth Amendment jurisprudence. A removal pursuant to an authority, including, but not limited to, as provided in Section 22651, that is based on community caretaking, is only reasonable if the removal is necessary to achieve the community caretaking need, such as ensuring the safe flow of traffic or protecting property from theft or vandalism. (c) Those law enforcement and other agencies identified in this chapter as having the authority to remove vehicles shall also have the authority to provide hearings in compliance with the provisions of Section 22852. During these hearings the storing agency shall have the burden of establishing the authority for, and the validity of, the removal. (d) This section does not prevent a review or other action as may be permitted by the laws of this state by a court of competent jurisdiction.
