The short answer
A sound, lost item, or report does not establish who is in a home. Put safety first, check facts from a lawful distance, and confirm the occupancy rules before deciding what to do.
On this page
Separate a report from a conclusion
Write down what was reported, when it happened, where it was observed, and who directly observed it. A noise, unlocked door, moved object, or visitor does not by itself establish that an unknown person lives in the rental or has broken the law. Avoid labels such as phrogger, squatter, or intruder until qualified authorities assess the facts.
Keep an ordinary guest, authorized household member, caregiver, current renter, former renter, and person who never had permission distinct. Their rights and the lawful next step may differ. Do not infer a person's motives, health, or tenancy status from a rumor or appearance.
Protect people from immediate danger
If a resident or visitor believes an unknown person may be inside now, tell them to move to a safe place and contact emergency services. Do not enter to search, confront anyone, follow a person, or ask a resident to investigate alone. Keep the exit clear and tell responders what was directly observed, not what is assumed.
A carbon-monoxide alarm or symptoms that could indicate exposure are a separate urgent hazard. Follow the CPSC guidance: move outside to fresh air, call emergency services or 911, and do not re-enter until responders allow it. Do not use unusual sounds or a resident's concern to diagnose carbon-monoxide exposure.
Speak with the resident calmly and privately
When there is no immediate emergency, contact the resident through a safe, private channel. Ask what they observed, whether anyone was expected or authorized to enter, and whether they need help. Explain what you will check and when you will follow up. Do not accuse, threaten, promise a police outcome, or ask the resident to confront another person.
Keep sensitive details limited to the people who need them to respond. A report of possible entry is not permission to discuss another resident's private information or to expand an occupancy investigation beyond the facts.
Preserve evidence without intrusive monitoring
Keep dated copies of reports, messages, visible damage, and actions taken. Photograph a condition only from a place you may lawfully access and when it is safe. Do not enter an occupied area, crawlspace, or another unit to look for a person or gather evidence.
Do not install a hidden camera, track a resident or visitor, or record inside a home to test a suspicion. If a security device is being considered, first check applicable privacy, notice, consent, lease, and local requirements with qualified advice. Cameras and alarms do not replace a lawful inspection or emergency response.
Use lawful access and qualified help
If there is credible concern but no immediate danger, contact the appropriate local law-enforcement or safety agency for direction. A landlord is not an investigator. Preserve the report and ask what evidence or information the agency needs; do not make a criminal allegation you cannot support.
For an occupied rental, follow the agreement and current local entry rules before any inspection. Emergency-entry rules and notice requirements vary. If the person's status is unclear, do not change locks, shut off utilities, remove belongings, or demand that someone leave outside the required process. See the rental entry overview and unauthorized-occupant response guide.
Maintain routine property safety
Keep exterior doors, windows, locks, and required alarms in good repair. Give residents a clear way to report a broken lock, damaged entry, or urgent safety concern. Arrange inspections and repairs using the agreement, proper notice, and the rules for the property; do not turn a suspicion into repeated or unannounced entry.
Use the maintenance record to track the report, authorized access, work performed, and follow-up. A software record can help keep the timeline organized; it does not inspect a unit, determine who entered, or provide security or law-enforcement services.
Resolve occupancy questions separately
Once immediate safety has been addressed, review the lease, documented permission, communications, and local occupancy rules. A guest, household member, caregiver, former renter, and never-authorized person may require different procedures. Ask a qualified local housing professional or attorney before notice or enforcement when status is uncertain.
If everyone agrees to an occupancy change, decide in writing whether the person is a tenant or another authorized occupant and use the required agreement. Update access and emergency records only after the proper process is complete. Rentari provides rental software and written guides; it does not provide licensed property management, on-site inspection, private security, tenant placement, legal representation, or occupant removal.
A longer visit does not settle legal status
A guest, a person authorized to live in the home and a tenant with rights under an agreement are different questions. There is no nationwide number of nights that answers all three. Review the actual permission, agreement and applicable law; a signature is not always required. For example, Florida section 83.43 includes certain oral rental agreements and defines tenancy by entitlement to occupy under an agreement. This is a Florida definition, not an automatic guest-conversion rule.
Ask the resident whether the visit is temporary, its expected end, whether permission was given and whether a household change is requested. Keep relevant dates and direct statements. A key, delivered mail or regular presence can prompt a conversation but does not independently decide legal rights. Do not open mail, track visitors or infer status from a relationship, age or caregiving role.
Check whether the guest policy can lawfully apply
Read any duration, permission and occupancy terms together with current law before calling a visit a violation. A lease clause cannot remove a statutory right. New York Real Property Law 235-f, for example, permits specified additional occupants subject to its conditions and preserves lawful occupancy-code limits. It also distinguishes those occupants from tenants and addresses what happens when the tenant leaves. Check the facts and applicable housing rules rather than transplanting this example to another state.
If a resident requests an exception because of a disability, consider the accommodation through the proper process. HUD and DOJ guidance explains that requests can be oral, need no special terminology and require prompt consideration. Ask only for information necessary to evaluate the disability-related need and keep it confidential. Do not automatically treat a support person's stay as a lease violation or require a new lease before reviewing the request.
Document the agreed change without assuming an outcome
After the legal and permission review, record whether the visit remains temporary, an authorized occupant is being added or a tenancy agreement needs to change. State the agreed dates, role and permitted access. Adding a name to a record does not itself determine legal status. If screening is lawful and appropriate for a proposed tenant, use the established criteria, consent and privacy process; do not automatically screen every visitor or accommodation support person.
If a guest offers payment, record who is paying and what obligation the payment concerns, then obtain local advice before treating acceptance or refusal as a tenancy rule. The payment-method guide explains why lease, law and case stage matter. If the parties disagree about continued occupancy, use qualified advice and the required notice or court process already described above. A declined lease amendment alone does not establish that removal is lawful.

Common questions
What should I do if someone may be inside the rental now?
Move to safety and contact emergency services. Do not enter to search, confront anyone, or ask a resident to investigate. Share direct observations with responders.
Does a sound or missing item prove an unknown person lives there?
No. Record what was directly observed and check the facts through a lawful process. A report alone does not establish identity, permission, criminal conduct, or tenancy status.
Can I install a hidden camera to confirm an unauthorized occupant?
Do not secretly record or track people. Before considering any security device, check the applicable privacy, notice, consent, lease, and local requirements with qualified advice.
What should I do if a carbon-monoxide alarm sounds?
Follow CPSC guidance: leave for fresh air, call emergency services or 911, and do not re-enter until responders allow it. Do not try to locate the source yourself.
Does a guest become a tenant after 14 days?
There is no universal 14-day rule. Review actual permission, agreements and current law for the property. Nights stayed, keys or mail alone do not settle occupancy or tenancy rights.
Must every person living in a rental sign the lease?
Authorized occupancy and contractual tenancy can differ, and some rental agreements can be oral. Applicable occupant rights and accommodation duties may limit a lease requirement. Confirm the person's role and local rules before requiring a new contract.
Can I enforce the guest limit without considering a requested disability exception?
Review a disability-related accommodation request promptly through the appropriate process, even if made orally. Seek only necessary information and protect confidentiality; a lease clause does not remove accommodation duties.
