Quick answer

As a rule, a search of a person or place requires a search warrant issued by a judge upon probable cause. The Rules and jurisprudence recognize exceptions, one of the most important being a search incidental to a lawful arrest. Under this exception, a person lawfully arrested may be searched, without a separate search warrant, for dangerous weapons or anything which may have been used or may constitute proof in the commission of an offense. A critical point is the sequence: the arrest must come first and must be lawful; the search is justified because it is incidental to that lawful arrest. If the arrest is unlawful, the search that follows is also unlawful, and its fruits are inadmissible; the prosecution cannot justify an arrest by pointing to what an illegal search turned up (the process cannot be reversed). The permissible scope of a search incidental to arrest is limited to the person of the arrestee and the area within their immediate control, that is, the area from which they might gain possession of a weapon or destructible evidence; it does not extend to a general exploratory search of the entire premises. Other recognized warrantless-search exceptions include: a search of a moving vehicle (given the practical impossibility of securing a warrant); seizure of evidence in plain view; a consented search (voluntary and clearly given); a stop-and-frisk (a limited protective pat-down based on a genuine reason to believe the person is armed and dangerous); customs searches; and searches under exigent circumstances. Evidence obtained from a valid warrantless search is admissible; evidence from an invalid one is excluded. So a lawful arrest permits a search of the arrestee and their immediate reach without a separate warrant, but the arrest must be lawful first, and the scope is limited.

The Rule and This Exception

A search generally needs a warrant, but a search incidental to a lawful arrest is a recognized exception: a lawfully arrested person may be searched without a separate warrant for weapons or evidence.

The Arrest Must Come First

The arrest must precede the search and must be lawful. If the arrest is unlawful, the search is too, and its fruits are inadmissible — the process cannot be reversed to justify the arrest by what the search found.

Limited Scope and Other Exceptions

The scope is limited to the arrestee's person and immediate control — not a general search of the premises. Other exceptions: moving vehicle, plain view, consented search, stop-and-frisk, customs, exigent circumstances.
