Is a probation officer required to know where a probationer lives?

The People do not specifically address defendant's concerns but assert that "[a] probation officer supervising someone like [defendant] must reasonably know where and with whom she resides." Relying on People v. Olguin (2008) 45 Cal.4th 375 (Olguin), the People argue that "[i]f it is permissible to place restrictions on a probationer's place of residence, it is certainly permissible to require that she give 24 hours' notice of any contemplated changes to her address or her roommates."
