Finding someone who is not listed on the lease living in your rental property can raise concerns. In Pennsylvania, an unauthorized occupant may be grounds for eviction if the tenant’s conduct violates the rental agreement. The rental terms, the person’s right to live there and court procedures matter.
Check whether the lease prohibits the occupancy
Your lease is the starting point. It may limit additional residents or long-term guests. An occasional guest is not necessarily an unauthorized occupant, so records showing that the person actually lives there can help establish the alleged violation.
Pennsylvania law distinguishes a tenant from someone who never had the legal right to occupy the property. A person may qualify as a tenant through an oral or written lease, your permission, including permission shown through your actions or acceptance of rent. An unnamed occupant may also ask the court to recognize them as a tenant.
Confirm the notice requirements
For an unauthorized-occupancy lease violation, Pennsylvania law generally requires 15 days’ notice for an agreement of one year or less or one without a fixed end date and 30 days for a lease longer than one year. However, your agreement may shorten or eliminate that notice period. Occupancy restrictions also must comply with fair housing laws.
Use the court process to regain possession
If the violation remains unresolved, you may file a landlord-tenant complaint in the appropriate local court. The lease, notices, correspondence and records showing ongoing occupancy may help establish the alleged breach.
A judgment for possession, which gives you the legal right to regain the property, does not authorize immediate removal. In a residential case, you generally may ask the court for an Order for Possession after the 10th day following judgment. After the order is served, an officer may restore possession on or after the 11th day following service if the occupants remain. An appeal or court order temporarily stopping the eviction can delay the process.
Why early legal guidance can prevent setbacks
Unauthorized occupancy disputes are not always straightforward. Small differences in the facts can affect how you present your case and how efficiently it moves through court. Legal guidance can help you identify potential weaknesses before they cause court delays or require you to restart part of the process.
