How can a landlord legally increase rent?

A landlord can legally increase rent by issuing a notice in accordance with lease terms or local laws. This approach ensures that the landlord is following proper legal procedures, which may include providing the tenant with adequate notice and a specific timeframe within which the increase will take effect. Many jurisdictions have rules regarding how much notice must be given for rent increases, and these rules often vary depending on the type of lease—whether it is a month-to-month rental agreement or a fixed-term lease. Following these legal requirements helps to protect both the landlord's right to adjust rent and the tenant's right to be informed and prepared for such changes.

The other methods presented would generally not be considered legal or appropriate. For example, refusing to provide necessary services until a tenant agrees to a rent increase can lead to claims of harassment or constructive eviction. Eliminating tenant rights is not a valid basis for increasing rent and could violate local housing regulations. Simply informing a tenant verbally of a rent increase lacks the formal notification needed to make the increase legally binding, as written documentation is typically required.
