Is a probationer's search condition within an exception to the Fourth Amendment?

an adult probationer's search condition comes within an exception." (People v. Hoeninghaus (2004) 120 Cal.App.4th 1180, 1184 (Hoeninghaus).) That exception is based on consent: A person who voluntarily accepts a grant of probation subject to a condition allowing warrantless searches has consented to such searches, and a "search conducted pursuant to a valid consent does not violate the Fourth Amendment unless the search exceeds the scope of the consent." (People v. Bravo (1987) 43 Cal.3d 600, 605.) "[T]he exception is inapplicable[, however,] if police are unaware of the probation search condition at the time of a warrantless search." (Hoeninghaus, at p. 1184.)
