Which of the following could constitute grounds for a tenant’s eviction?

Consistent late payment of rent can be grounds for a tenant’s eviction because it directly violates the lease agreement that typically stipulates rent must be paid on time. When a tenant is late in making payments, it undermines the financial agreement made between the landlord and tenant, potentially affecting the landlord's ability to cover expenses related to the property. Most states, including Montana, allow landlords to pursue eviction for tenants who repeatedly fail to pay rent on time, especially after proper notices have been given. This demonstrates a fundamental breach of the rental agreement, justifying the landlord's action to seek eviction.

The other options do not represent valid grounds for eviction. Personal belongings left in the unit may indicate that a tenant has not abandoned the property. Providing notice of intent to leave is a tenant's right and actually shows compliance with lease terms. Improvement projects on the unit, if performed with proper notice and adherence to lease terms, usually would not serve as a basis for eviction, provided they do not violate any specific agreements between the landlord and tenant.
