What is a Commercial Lease Addendum?

Commercial Lease Addendum Definition

A commercial lease addendum is a supplemental document attached to a primary commercial lease agreement, outlining additional terms, clarifications, or modifications specific to a business-related context. This addendum allows parties to address evolving needs or unique circumstances without altering the foundational lease contract. Once executed, the addendum becomes an integral part of the lease, holding the same legal weight as the original document.

Commercial Lease Addendums Explained

Imagine you’ve got a main rulebook for renting a business space, but then, a unique situation pops up. A commercial addendum is like an extra page or chapter you add to that rulebook. Let’s say a business wants to add outdoor seating or requires additional storage; an addendum can make it official. It’s a flexible way to cater to specific business needs without rewriting the whole contract. Both the landlord and the business sign it, making it a firm part of the deal. This ensures that as business dynamics change, the rental terms can smoothly adapt too.
