An addendum to a tenancy agreement is a legal document that modifies or supplements the original agreement. It is often used to address changes that occur after the initial agreement is signed, such as:
Changes in rent: Increasing or decreasing the monthly rent.

Content
Be concise and clear: Use simple language and avoid legal jargon that may be difficult to understand.
Signatures
Obtain signatures from all parties: Both the landlord and the tenant must sign the addendum to make it legally binding.
