Can a police officer search a probationer's home without a warrant?

"In People v. Woods, supra, 21 Cal.4th 668, two persons who resided with a probationer challenged the constitutionality of a warrantless search of their home by a police officer who relied on the authority of a known search clause to seek incriminating evidence against another party residing in the home. (21 Cal.4th at pp. 672-673.) In evaluating the legality of the search, we found it appropriate to apply an objective standard. In the context of probation searches, we explained, the question is whether the circumstances, viewed objectively, show a proper probationary justification for an officer's search; if they do, then the officer's subjective motivations with respect to a third party resident do not render the search invalid. [Citations.] We concluded there that, regardless of the searching officer's ulterior motives, the circumstances presented ample justification for a search pursuant to the probation clause at issue because the facts known to the officer showed a possible probation violation.
