A lease addendum is an attachment that modifies or provides supplemental information to a lease agreement. It is a separate document that clarifies, expands, or changes specific sections of a lease. Disclosures are often added in the form of an addendum to provide information imposed by local or state laws.

Addendum vs Amendment

An addendum generally provides additional information to a lease, while an amendment changes the fundamental terms of a lease (e.g., rent amount, end date, etc.). Amendments are modifications made to the original lease agreement form (with approval by both landlord and tenant) whereas an addendum is a separate document that will be attached to the lease once it has been signed by both parties.

How to Add to a Lease

An addendum is added by referencing the original lease. This is accomplished by mentioning the lease date, which is found in the first section of the lease, and the rental property address. Once an addendum is signed by both the landlord and the tenant, it becomes legally binding.

Frequently Asked Questions

Can a tenant refuse to sign a lease addendum?

Yes. Tenants have the right to reject a lease addendum by not signing. The landlord then has the option to either stick with the original terms, attempt to negotiate the proposed terms with the tenant, or end the lease agreement. However, the landlord must adhere to the termination provisions of the lease agreement as well as local and state landlord-tenant laws.

Can an addendum be used to terminate a lease agreement?

No. A lease addendum can’t be used to terminate a lease agreement. Sometimes the lease termination date can be changed, but only if both parties agree to it. It should be noted that changing the termination date can affect many other provisions of the lease, so it should be done only with careful consideration and negotiation.
