Is a squatter a tenant — and what rights do they have?
No. Idaho keeps them in different statutes from tenants: the eviction statute is written about "a tenant", and the squatter is handled under a separate statute, written about someone who walked in while you were away and will not leave. The fast sheriff route exists only where the person was never your tenant, and being inside without permission is a crime.
›Read the law — 3 provisions
If a trespasser counts as a tenant, the owner is routed into housing court and every fast option closes.
1 · Idaho Code § 6-303 — unlawful detainer defined
“A tenant of real property, for a term less than life, is guilty of an unlawful detainer:”
Only the opening clause is quoted, because that clause is the whole point: every one of the five numbered situations that follows it hangs off the word "tenant".

“Every person is guilty of a forcible detainer who either: 1. By force, or by menaces and threats of violence, unlawfully holds and keeps possession of any real property, whether the same was acquired peacefully or otherwise; or 2. Who during the absence of the occupant or property owner of any lands, unlawfully enters upon real property, and who, after demand made for the surrender thereof, refuses to surrender the same to such former occupant or property owner. The occupant of real property, within the meaning of this subdivision, is one who, within five (5) days preceding such unlawful entry, was in the peaceable and undisturbed possession of such lands, regardless of whether the property was inhabited by the occupant of real property.”
Read the last sentence of subdivision 2 with a vacant house in mind. It defines the "occupant" whose absence matters as one who was in peaceable possession within five days before the entry — and the 2017 amendment added the words "regardless of whether the property was inhabited". A demand for surrender is an element.

“(f) The unauthorized person or persons are not current or former tenants pursuant to a written or oral rental agreement authorized by the property owner; (g) The unauthorized person or persons are not immediate family members of the property owner; and (h) There is no pending litigation related to the real property between the property owner and any known unauthorized person.”
Note what these conditions do to the boundary. A former tenant who overstays, a relative, or anyone you are already in litigation with is OUTSIDE this section entirely — that is the ordinary court track in the same chapter. Note also that an oral rental agreement counts.
