Your attachments should also be referenced in the lease itself.
Official - Attachment to Commercial Lease Important to Know: When preparing two or more attachments, number them consecutively (Attachment Number 1, Attachment Number 2 and so on).That way, you leave the original lease easy to read, thereby avoiding miscommunication and misunderstandings. An attachment is legally part of a lease, and may include plans and specifications for improvements to be made by you or the landlord, a drawing showing the exact location of your space in a building, or a list of new equipment that the landlord will provide. If you need to include lengthy, detailed information on your commercial lease, it's best to use an attachment.
