Good question. Look at the terms of the PTI contract first. Most mirror that of a standard probation orders. As it applies to probation, generally, a standard condition is that the probationer "consents" to a search of his or her person and home (vehicles not mentioned). But even those probationary searches are limited as to what can be used to form the basis for a new charge. See for example, Gordon v. State, 1 So.3d 1117 (Fla. 1st DCA 2009).
Lastly, while I hate to state the obvious, particularly if you are PTI for some other crime, it's a good idea to not have anything illegal on your person, in your home, or in your vehicle.
I assume that pretrial intervention in FL is similar to DEJ or deferred entry of judgment here in CA. It is a form of pretrial diversion , usually for drugs. Search terms are included as a requirement to participate in the program.
