If your unlawful detainer case is assigned to Department 501, then you may schedule an ex parte hearing by contacting the Law and Motion phone line at (619) 450-7371 or by going to the Civil Business Office to schedule an ex parte date with the clerk.
If your unlawful detainer case is assigned to a department other than Department 501, then you will need to contact that department's calendar clerk to schedule an ex parte date. Department contact information may be found here.
