A commercial lease addendum makes a change to the terms of a pre-existing lease agreement. Upon the addendum being signed by both parties, the modification may be any request by the landlord or tenant. Common addendums include extending the lease, changing the rent, rights to repair, or any other terms that need to be amended.
