Idaho Squatters Rights: Adverse Possession and How Removal Actually Works
How long adverse possession takes in Idaho, whether there is a fast-track removal law, and what you legally can and cannot do about an unauthorized occupant. Last reviewed August 2026.
The question that decides everything: is the occupant a squatter or a tenant? Anyone who ever had permission to be there — a former tenant, someone who paid you rent even once, an ex-partner of your tenant on the lease — is generally a tenant in the law's eyes and must go through the eviction process. Idaho's squatter rules below apply to true trespassers only.
How long does adverse possession take in Idaho?
Idaho is among the strictest states: an adverse possessor must hold the property openly and continuously for 20 years and pay all taxes levied on it throughout that period. Idaho Code § 5-210 governs oral claims (possession by enclosure, cultivation, or improvement), and §§ 5-207 to 5-208 cover claims founded on a written instrument, with the same 20-year and tax-payment requirements. The legislature raised the period from 5 to 20 years in 2006, and the tax requirement alone defeats nearly every residential squatter.
How to remove a squatter in Idaho
Idaho Code § 6-310A, added by H.B. 321 (2025 ch. 222) effective July 1, 2025 and amended in 2026 (ch. 82), gives owners a non-judicial removal route modeled on Florida's law. The owner or authorized agent submits a verified complaint to the county sheriff attesting, among other things, that the occupants unlawfully entered, were directed to leave, and are not current or former tenants under any written or oral rental agreement (§ 6-310A(2)(f)). The sheriff then serves a notice to immediately vacate without any court case, and the owner can retake possession. The safeguard is a stiff wrongful-removal remedy: a person wrongly removed may recover actual damages plus statutory damages equal to triple the fair market rent, costs, and attorney's fees. Occupants outside the statute's scope still require an unlawful detainer action under Idaho Code § 6-303 and a sheriff-executed writ of restitution.
Squatter or tenant? Why it matters
Section 6-310A(2)(f) walls the sheriff procedure off from landlord-tenant disputes: anyone who is or ever was a tenant under a written or oral rental agreement cannot be removed this way, no matter how far behind on rent. Those occupants require the standard 3-day notice under Idaho Code § 6-303 and an unlawful detainer judgment, and misusing the squatter procedure against them triggers the triple-fair-market-rent wrongful-removal remedy.
What you absolutely cannot do
Idaho landlords may not lock out an occupant with any colorable tenancy, remove belongings, or shut off utilities to force a move-out; the lawful routes are the § 6-310A sheriff process for true squatters or an unlawful detainer action for everyone else. Under Idaho Code § 6-317 a court may award three times the actual damages for a forcible or unlawful exclusion. The widely repeated claim that § 6-320 gives a flat three months' rent for a lockout is wrong -- that section covers habitability and deposit failures.
Recent changes to the law
H.B. 321 (2025, ch. 222) created Idaho Code § 6-310A effective July 1, 2025, establishing sheriff-executed removal of unauthorized occupants on the owner's verified complaint, with no court filing, express exclusion of current and former tenants, and a wrongful-removal remedy of actual damages plus triple fair market rent, costs, and fees. The section was amended in 2026 (ch. 82). Idaho's adverse possession rules were not changed and remain among the nation's strictest.
What Idaho property owners get wrong
Owners misuse § 6-310A in two ways: swearing the occupant was never a tenant when there was once an oral arrangement (the statute counts oral agreements, and the triple-rent penalty attaches), and assuming the sheriff will investigate for them -- the verified complaint is the owner's sworn responsibility. On the adverse-possession side, owners overestimate the risk: with a 20-year period plus a tax-payment requirement, no ordinary squatter acquires title in Idaho, so the urgency is about removal cost, not ownership loss.

Frequently asked questions
How long does a squatter have to stay in Idaho to claim ownership?
Twenty years -- and the squatter must also pay all property taxes levied during that entire period under Idaho Code § 5-210. Idaho raised the period from 5 to 20 years in 2006, and the combination of two decades of open possession plus continuous tax payment makes successful residential adverse-possession claims essentially nonexistent.
How do I remove a squatter in Idaho?
Since July 1, 2025, submit a verified complaint to the county sheriff under Idaho Code § 6-310A attesting that the occupants unlawfully entered, were told to leave, and were never tenants under any written or oral agreement; the sheriff serves a notice to immediately vacate with no court case required. If the occupant is or ever was a tenant, you must instead serve notice under § 6-303 and win an unlawful detainer judgment and writ of restitution.
What happens if an owner misuses Idaho's squatter removal law?
A person wrongly removed under § 6-310A may sue and recover actual damages plus statutory damages equal to triple the fair market rent of the property, along with costs and attorney's fees. That is why the verified complaint's conditions -- especially that the occupant was never a tenant under any written or oral agreement -- must genuinely be true.
Can Idaho police remove a squatter without the § 6-310A process?
For a caught-in-the-act intruder, officers can act under the criminal trespass laws. But once someone is settled in and claims a right to be there, law enforcement historically treated the dispute as civil -- which is exactly the gap the 2025 sheriff-complaint procedure was written to close. Using the § 6-310A paperwork gives the sheriff a statutory basis to act instead of a judgment call.
