How to Handle Unauthorized Occupants in a Rental Unit
March 21, 2023An unauthorized occupant — someone living in the unit who isn't named on the lease — creates real exposure: they haven't been screened, they're not contractually bound to lease terms, and their presence can affect occupancy limits and insurance coverage.
1. Confirm it's actually happening
A guest staying a few nights isn't the same as an unauthorized occupant living there full-time. Look for signs like mail addressed to a different name, a consistent presence during inspections, or the leaseholder's own admission — document what you observe with dates.
2. Check your lease's guest and occupancy clauses
Most leases specify a maximum guest stay before someone is considered an occupant requiring lease addition and screening (commonly somewhere around 14-30 days), along with a maximum total occupancy. These clauses are what give you standing to act.
3. Address it directly with the leaseholder first
Raise the issue directly and give the tenant the option to formally add the person to the lease (subject to your normal screening process) or have them move out. Many situations resolve simply once addressed rather than requiring formal enforcement.
4. Screen and add them properly if they're staying
If the tenant wants the person to stay long-term, run them through your normal screening process and add them to the lease as a co-tenant — this protects you by making them contractually bound to lease terms and gives you accurate occupancy records.
5. Treat it as a lease violation if it isn't resolved
If the tenant refuses to address an unauthorized occupant after being notified, it's a lease violation like any other — proceed with your standard cure-or-quit notice process, documenting the situation clearly for the file.
Frequently Asked Questions
How do I know if someone is an unauthorized occupant versus just a guest?
Most leases define a guest limit — commonly somewhere around 14-30 consecutive or cumulative days — beyond which someone is considered an occupant requiring formal lease addition. Check your specific lease language for the exact threshold.
Can I add an unauthorized occupant to the lease after the fact?
Yes, and it's often the cleanest resolution — run them through your normal screening process and formally add them as a co-tenant, which makes them contractually responsible for lease terms going forward.
Is an unauthorized occupant grounds for eviction?
It can be, if your lease includes an occupancy or unauthorized occupant clause and the tenant doesn't resolve it after being given proper notice — the same cure-or-quit process applies as with any other lease violation.
Does an unauthorized occupant affect my insurance?
Potentially — many landlord insurance policies are written around the named tenants on file, and an unscreened, undisclosed long-term occupant could complicate a claim. It's worth checking with your insurer if you're unsure how your policy treats this.
What if the unauthorized occupant is a newborn baby or new spouse?
These situations are usually handled cooperatively — most leases don't intend to penalize a tenant for a new family member — but it's still worth formally updating the lease to reflect actual occupancy and confirming you're not exceeding any legal occupancy limits for the unit.
