You notice an extra car in the driveway every morning. Then the neighbor mentions there’s someone new walking the dog. Then you see a second name on the Amazon packages piling up on the porch. Your tenant signed the lease alone, but someone has clearly moved in, and they never asked, never applied, and never passed a background check. Now you’re wondering whether you even have the right to do anything about it.

You do, but the path depends on what your lease says, how long the guest has been there, and whether the situation is a lease violation or just an uncomfortable conversation. In Nevada, there’s no single statute that defines when a guest becomes a tenant, so your lease language is the front line of enforcement. Here’s how to handle it legally, step by step.

When Does a Guest Become a Tenant Under Nevada Law

Nevada doesn’t have a specific statute that says “a guest who stays X days becomes a tenant.” Unlike some states that define guest-to-tenant conversion at 14 or 30 days, Nevada leaves this largely to the lease agreement and to the facts of the situation.

In practice, a guest is generally considered to have become an unauthorized occupant when they:

• Receive mail at the property
• Keep personal belongings, furniture, or clothing at the property
• Have a key
• Stay overnight more consistently than they’re absent
• Contribute to rent or utilities
• Use the property address on official documents (driver’s license, bank statements, employment records)

Any of these indicators, especially in combination, signal that the “guest” has become a resident. And once they’re a resident who was never screened, never approved, and never signed the lease, you have an unauthorized occupant problem.

This is why lease language matters more than statutory definitions. For the full legal framework governing lease terms in Nevada, see our Complete 2026 Guide to Nevada Landlord-Tenant Laws.

What Your Lease Should Say About Guests

The strongest protection against unauthorized occupants isn’t eviction, it’s prevention through clear lease language. Your lease should include all of the following:

• Named occupants. List every authorized occupant by name. Anyone not on the list is a guest.
• Guest stay limits. Define the maximum consecutive nights a guest can stay (common standard: 7–10 consecutive nights, or 14 nights total in any 30-day period) without prior written landlord approval.
• Notification requirement. Require the tenant to notify the landlord in writing if any guest will exceed the stay limit. This gives you a trigger point before the situation becomes a confrontation.
• Approval and screening clause. State that any person staying beyond the guest limit must apply as an occupant, pass screening, and be added to the lease via a lease amendment. No exceptions.
• Consequences. Specify that unauthorized occupants constitute a lease violation enforceable under NRS 40.2516 (5-day notice to cure or quit).

If your current lease doesn’t have these clauses, add them at the next renewal. For guidance on drafting a lease that covers these gaps, see How to Write a Nevada Lease Agreement That Protects You.

Why Unauthorized Long-Term Guests Are a Serious Problem

This isn’t about being controlling. Unauthorized occupants create real legal, financial, and safety exposure:

• No screening. Your tenant passed a background check, credit check, and income verification. Their guest didn’t. You have no idea about their criminal history, prior evictions, or financial stability. That person is living in your property on your tenant’s goodwill alone. See How to Screen Tenants in Nevada for why screening every occupant matters.
• Occupancy limits. Clark County and Henderson have residential occupancy standards tied to bedroom count and square footage.
• Exceeding occupancy limits can trigger code enforcement complaints from neighbors or HOA violations, both of which land on the owner.
• Insurance exposure. Your landlord insurance covers named tenants and authorized occupants. An unscreened person living in the property may not be covered, which means if they cause damage, start a fire, or injure someone on the property, your insurer may deny the claim.
• Increased wear and tear. More people means more water usage, more appliance wear, more foot traffic on flooring, and more stress on HVAC. You’re eating the increased operating cost without increased rent.
• Legal complications at eviction. If you eventually need to evict the tenant, an unauthorized occupant who has established residency may complicate the legal process, they may argue they’re a separate tenant entitled to their own notice and their own court hearing.

Step by Step, How to Handle Unauthorized Guests

Step 1, Document the Situation

Before you confront anyone, gather evidence. Note the extra vehicle (make, model, plates), the dates you observe the person at the property, any packages or mail addressed to them, and anything the neighbors have reported. If you have periodic inspection rights in the lease (with 24-hour notice under NRS 118A.330), schedule one, it gives you a legitimate reason to see who’s living there.

Step 2, Review the Lease

Pull the lease and check: is there a guest clause? A named-occupants clause? A stay-limit provision? If yes, you have a clear lease violation. If the lease is silent on guests, enforcement is harder, you’ll need to rely on the unauthorized-occupant argument and any applicable local occupancy codes.

Step 3, Send a Written Notice to the Tenant

Contact the tenant in writing, email or letter, not a text. Identify the concern: “We’ve observed a person staying at the property who is not listed as an authorized occupant on your lease.” Reference the specific lease clause being violated. State clearly: the guest must vacate, or the guest must apply to be added to the lease through your standard screening process. Give a reasonable timeline, typically 5–10 days.

Many tenants will resolve this at the written-notice stage. The guest leaves, or the tenant submits an application for the guest. Either outcome works.

Step 4, Formal Lease Violation Notice

If the tenant ignores the written notice and the unauthorized occupant remains, serve a 5-day Notice to Cure or Quit under NRS 40.2516. This is the formal lease violation notice. The tenant has five judicial days (excluding weekends and court holidays) to cure the violation, which means the unauthorized occupant leaves or applies and is approved, or vacate the property.

Step 5, If Not Cured, Eviction Filing

If the tenant doesn’t cure within the 5-day window, you can file for unlawful detainer through Las Vegas Justice Court. The court process follows the standard summary eviction timeline. This is the same enforcement path as any other lease violation, the fact that it’s a guest issue rather than a noise or damage issue doesn’t change the legal mechanics.

What Can Go Wrong

• Fair housing exposure. If the “guest” is the tenant’s partner or child, tread carefully. Familial status is a protected class under the Fair Housing Act. You can enforce occupancy limits and lease provisions, but you cannot target enforcement based on the relationship between the occupant and the tenant. Apply the same rules to every tenant uniformly.
• Retaliation claims. If the tenant has recently filed a habitability complaint or reported a code violation, they may argue your enforcement is retaliatory under NRS 118A.510. Document your timeline, the guest issue should predate any complaint for your enforcement to be cleanly defensible.
• Self-help eviction of the guest. You cannot personally remove the guest, change the locks, or confront the guest directly. Your lease is with the tenant, enforcement runs through the tenant, not through the guest. Attempting to physically remove an occupant (even an unauthorized one) can create liability for you.
• Guest who claims tenant status. If the guest has been there long enough to receive mail, establish residency, or argue they have a verbal agreement with the tenant, they may claim they’re a tenant with independent legal rights. This is messy and is exactly why you want to act early, before the guest digs in.

Catching a Long-Term Guest Early and Making the Stay Legitimate

Most owners only notice an extra occupant once the situation is already messy, after a neighbor complains or a second car is parked out front every morning. The cheaper path is to find out early, while the conversation is still friendly. Routine drive-bys, prompt follow-up on maintenance requests, and scheduled periodic interior and exterior property inspections tend to surface a long-staying guest long before it becomes an enforcement problem. When an inspection turns up a second toothbrush, a child’s room, or mail addressed to someone not on the lease, you have a documented starting point and a chance to ask questions calmly rather than reacting to a crisis.

Not every long guest is a fight you want. Sometimes the right move is to let the person stay legally instead of forcing them out. If your tenant has a partner or relative who has effectively moved in and the household is otherwise in good standing, the cleanest resolution is often to run that adult through your normal vetting and add them to the lease as a named occupant. Treat them exactly as you would a new applicant by using the same background and income screening you apply to every resident, so you are not approving an unknown person sight unseen. An occupant who passes screening and signs an addendum is far less of a liability than one quietly living off the books.

The lease renewal window is the natural moment to reset all of this. Before you offer another term, confirm who is actually living in the unit, update the named occupants, and re-state your guest policy in writing so there is no ambiguity going forward. Handling guest questions as part of disciplined, day to day Las Vegas property management keeps small overstays from hardening into the kind of unauthorized tenancy that is slow and costly to unwind.
