Section 22507 Of Chapter 9. Stopping, Standing, And Parking From California Vehicle Code >> Division 11. >> Chapter 9.

. (a) Local authorities may, by ordinance or resolution, prohibit or restrict the stopping, parking, or standing of vehicles, including, but not limited to, vehicles that are six feet or more in height (including any load thereon) within 100 feet of any intersection, on certain streets or highways, or portions thereof, during all or certain hours of the day. The ordinance or resolution may include a designation of certain streets upon which preferential parking privileges are given to residents and merchants adjacent to the streets for their use and the use of their guests, under which the residents and merchants may be issued a permit or permits that exempt them from the prohibition or restriction of the ordinance or resolution. With the exception of alleys, the ordinance or resolution shall not apply until signs or markings giving adequate notice thereof have been placed. A local ordinance or resolution adopted pursuant to this section may contain provisions that are reasonable and necessary to ensure the effectiveness of a preferential parking program.
  (b) An ordinance or resolution adopted under this section may also authorize preferential parking permits for members of organizations, professions, or other designated groups, including, but not limited to, school personnel, to park on specified streets if the local authority determines that the use of the permits will not adversely affect parking conditions for residents and merchants in the area.
