Arizona’s unwanted guest law lets a property owner remove someone who refuses to leave by giving at least five days’ written notice to vacate and, if the person still will not go, filing an eviction action in court.1Arizona Judicial Branch. Evicting Guests, Roommates, Family Members, and Other Unwanted Occupants from Your Home What trips people up is that the person on the couch may have quietly become a tenant under state law, which changes what you can and cannot do next.
When a Guest Becomes a Tenant
A guest is someone you invited to stay temporarily with no expectation of payment or ongoing arrangement. A tenant holds a rental agreement and has rights under Arizona’s Residential Landlord and Tenant Act. The complication is that Arizona defines “rental agreement” broadly to include written, oral, or implied agreements.2Arizona Legislature. Arizona Code 33-1310 – General Definitions Someone who arrived as a houseguest can cross into tenant status without ever signing a lease.
No Arizona statute names a specific number of days that automatically converts a guest into a tenant. Courts look at the facts on the ground. Is the person contributing money toward rent or utilities? Are they trading chores or services for the place to stay? Do they get mail at your address? Have they moved in furniture or treat the space as home? The more of these that apply, the stronger the case for tenancy, even without a written lease.
This matters because tenants are entitled to formal eviction proceedings with proper notice and a court hearing. When the status is unclear, Arizona courts tend to err toward treating the occupant as a tenant. If there is any real doubt, assume the formal eviction process applies.
How Verbal Arrangements Create a Tenancy
If you told someone they could stay in exchange for helping with groceries, splitting the electric bill, or handling yard work, a court can treat that conversation as a verbal rental agreement. At that point the person is a tenant with the right to contest an eviction.
Proving what was actually said is hard, so these disputes often turn on circumstantial evidence. Text messages, Venmo payments labeled “rent” or “utilities,” and testimony from other household members all become relevant. If the occupant can show they gave something of value for the right to stay, the scale tips toward tenancy.
The practical lesson: if you let someone move in, put the terms in writing on day one. A short agreement stating the arrangement is temporary, naming an end date, and saying no tenancy is created gives you much better footing if you later need the person out.
How to Remove an Unwanted Guest
Even when the person is clearly a guest and not a tenant, Arizona law still expects you to go through an orderly process. The paperwork takes time, but it keeps you out of far worse trouble.
Give Written Notice to Vacate
Start with a written notice. Arizona courts recommend at least five days’ notice for someone who is not a tenant.1Arizona Judicial Branch. Evicting Guests, Roommates, Family Members, and Other Unwanted Occupants from Your Home The notice should include the date you are giving it, a clear statement that the person must leave, the deadline for departure, and your signature. Hand it to the person if you can, and keep a dated copy for yourself. If hand delivery is not possible, posting it on the door and mailing a copy gives you a paper trail.
Arizona does not mandate a specific form for an eviction notice, and courts cannot enforce one.3Arizona Legislature. Arizona Code 12-1175 – Complaint and Answer; Service and Return; Notice and Pleading Requirements A clear, simple letter works.
File a Forcible Detainer Action
If the person ignores the notice, file a forcible detainer action with the clerk of the superior court or a justice of the peace.3Arizona Legislature. Arizona Code 12-1175 – Complaint and Answer; Service and Return; Notice and Pleading Requirements Your complaint describes the property and explains why you are entitled to possession. A summons is issued no later than the next business day after filing. Filing fees vary, but most Arizona justice courts charge under $100.
At the hearing, both sides present their case and the judge decides whether the person has any legal right to stay. If you win, the court enters a judgment granting you possession.
Wait for the Writ of Restitution
After the ruling, a writ of restitution cannot be issued until five calendar days have passed since the judgment.4Arizona Legislature. Arizona Code 12-1178 – Judgment; Writ of Restitution; Limitation on Issuance; Criminal Violation; Notice Once that period ends, law enforcement can execute the writ and physically remove the person. The statute requires enforcement “as promptly and expeditiously as possible,” though actual timing depends on the local sheriff or constable’s workload.
One useful detail: if the person returns to the property after being lawfully served with the writ, they commit third-degree criminal trespass, and the court is required to warn them of that at the hearing.4Arizona Legislature. Arizona Code 12-1178 – Judgment; Writ of Restitution; Limitation on Issuance; Criminal Violation; Notice
When the Police Can Help
A person commits third-degree criminal trespass by knowingly remaining on real property after a reasonable request to leave from the owner, someone else with lawful control, or a law enforcement officer acting on the owner’s behalf.5Arizona Legislature. Arizona Code 13-1502 – Criminal Trespass in the Third Degree; Classification This is a class 3 misdemeanor and is the trespass charge most likely to apply to an unwanted houseguest.
In practice, officers responding to an unwanted guest call generally evaluate whether the person had initial permission to be there and whether that permission was clearly revoked. They may give the person a chance to leave voluntarily, issue a citation, or make an arrest depending on the circumstances. Having your written notice to vacate in hand when officers arrive strengthens your position considerably. Police response alone does not always resolve the situation, especially where the person has arguable tenant status; in that scenario officers often tell both parties it is a civil matter and point you back to the eviction process.
Why You Cannot Just Change the Locks
Changing the locks, shutting off the water, or putting someone’s belongings out on the curb may feel justified. If the person qualifies as a tenant, those moves expose you to real financial liability. Under Arizona’s landlord-tenant statute, a tenant who is unlawfully removed or locked out can recover possession and collect up to two months’ rent or twice their actual damages, whichever is greater.6Arizona Legislature. Arizona Code 33-1367 – Tenant’s Remedies for Landlord’s Unlawful Ouster, Exclusion or Diminution of Services The same rule applies if you intentionally cut off electricity, gas, water, or any other essential service.
Even when you are confident the person is only a guest, self-help can backfire. If they file a police report or sue and a court later decides they had tenant status, you are the one defending an illegal lockout. The formal process is slower, but it puts a judge and law enforcement between you and the confrontation.
Protect Yourself With Documentation
Your written notice to vacate is the single most important document, so draft it carefully and keep a dated copy. Beyond the notice, save every text message, email, and voicemail connected to the situation. After in-person conversations, send a follow-up text or email summarizing what was said so there is a written record. Photograph any damage. If the person made financial contributions, keep records of those too; payment history is one of the strongest signals a court uses when deciding guest versus tenant status. The same evidence helps if you need to call police about a trespass.
If the Guest Is an Active-Duty Service Member
Federal law adds protections you need to know about before serving notice on an active-duty service member. The Servicemembers Civil Relief Act requires a court order before any eviction can proceed against a service member or their dependents when the monthly rent falls below an annually adjusted threshold.7Office of the Law Revision Counsel. 50 USC 3951 – Evictions and Distress If military duty materially affects the person’s ability to appear or pay, the court must grant a stay of proceedings for at least 90 days and can extend it. Self-help measures are prohibited against covered service members regardless of the rent amount. The protection reaches all active-duty branches, National Guard members on federal orders for more than 30 consecutive days, and commissioned officers of the Public Health Service and NOAA.
What to Do With Belongings They Leave Behind
If the person had tenant status, Arizona law requires you to inventory the remaining property and notify them of its location and storage costs by certified mail and by posting a notice on the door.8Arizona Legislature. Arizona Code 33-1370 – Abandonment; Notice; Remedies; Personal Property; Definition You then hold the property for 14 calendar days using reasonable care. During that period the former occupant has the right to retrieve personal identification documents, financial records, immigration documents, clothing, and tools of their trade without paying storage costs first.
After the 14 days pass with no reasonable effort to recover the belongings, you can donate, sell, or dispose of them. Any sale proceeds go first to unpaid rent and your removal and storage costs, with any excess mailed to the person’s last known address.8Arizona Legislature. Arizona Code 33-1370 – Abandonment; Notice; Remedies; Personal Property; Definition One shortcut: if the former occupant returned the keys to you, you can immediately dispose of any remaining property without waiting the 14 days.
