The court shall set a hearing to be held within 15 days, excluding Saturdays, Sundays, and holidays, after its receipt of the second certificate. The court shall direct that notice of the time and place of hearing be served upon the respondent, his or her attorney, and guardian, if any, and his or her responsible relatives. The respondent may remain at his residence pending the hearing. If, however, the court finds it necessary, it may order a peace officer or another person to have the respondent before the court at the time and place set for hearing.
