What constitutes "breach of lease"?

A breach of lease refers to any violation of the terms and conditions specified in a lease agreement by either party involved. This encompasses a wide range of infractions, including failure to fulfill contractual responsibilities, such as not paying rent, failing to maintain the property, or even wrongful termination of the lease by the landlord. The reason this answer is comprehensive is that it encapsulates all potential breaches, not just those from the tenant, highlighting that both parties have obligations outlined in the lease agreement that must be adhered to.

The other options focus on specific scenarios that could indeed constitute a breach but do not capture the broader principle. For instance, the second choice mentions a delay in paying rent, which is certainly a breach, but it is just one example of a violation and does not cover the entire scope of what could constitute a breach of lease. The third option implies that a termination by the landlord is a breach, which is not necessarily the case if done in accordance with the lease terms. Lastly, alterations made without permission can be a breach as well; however, they are just specific acts of violation rather than a definition that encompasses the entirety of lease agreements. Therefore, the first option provides the most accurate and complete definition of what constitutes a breach of lease.
