A person who is leasing a residential property such as an apartment or home (tenant) may want to have a roommate stay at the leased premises. This is often a boyfriend or girlfriend but may also be a friend or family member who needs a place to stay for a short period of time—which then becomes a longer period of time.

If the tenant’s relationship with their guest takes a turn for the worse, or if the guest overstays their welcome, the tenant may not be able to remove or evict the guest from the leased premises (apartment or house) as quickly as the tenant imagined. Laws vary from state to state, but in some states such a guest who is not on the lease may become a legal tenant with certain rights after staying at the leased premises for a certain period of time. For example, the guest may become a month-to-month tenant with the right to at least 30 days written notice to move out or vacate the leased premises.

Having a roommate who has not been approved by the landlord and who has not signed and agreed to the terms of the lease agreement (is not on the lease) can cause additional legal problems for the tenant who signed the lease agreement. For example, most residential lease agreements limit the number of days (and nights) a person who has not signed the lease agreement (a guest) can stay at the leased premises. If a tenant violates this provision of the lease agreement by having guests for longer periods of time, the landlord may be able to terminate the lease and evict the tenant.

In North Carolina, tenants must be cautious when allowing someone to stay with them in a leased property. If a guest stays for an extended period, they may establish tenancy rights, even without being on the lease. North Carolina law typically requires a formal eviction process to remove someone who has become a de facto tenant, which includes providing proper notice. The duration that a guest must stay to be considered a tenant is not explicitly defined by state law and can depend on the circumstances. Additionally, most lease agreements have clauses that restrict the duration a guest can stay without landlord approval. If a tenant allows a guest to stay longer than permitted by the lease, this could be grounds for the landlord to terminate the lease and potentially evict the tenant. It is important for tenants to review their lease agreement and consult with an attorney if they are considering having a long-term guest or roommate to understand the potential legal implications.
