Updated August 30, 2023

A lease addendum is a separate legal document that allows a landlord to add additional information or make changes to a lease agreement. Instead of re-writing the contents of a lease, an addendum is a document that includes added language. After both parties sign, the addendum should be added to the original lease.

Disclosure” – Also referred to as a “disclosure,” and is attached to a lease that generally includes important information about the property.

What is a Lease Addendum?

A lease addendum, or an “addendum to a lease,” is a document that expands upon and gives more information related to a section or clause in a lease agreement. For example, there may be a section in a lease about specific rules regarding “pets” and reference an attached “pet addendum” that lists the set of rules.

With some addendums, such as the lead-based paint addendum, the tenant cannot enter the property until it has been signed and, therefore should be required before giving access.

Speak to the tenant and fully explain how the addendum affects the lease. Most often, an addendum will be a type of disclosure that explains the property rules. For example, if pets are allowed, a list of the sizes of pets and the types may be listed in the addendum.

2. Tenant Reviews the Addendum

The tenant should be given an ample amount of time to review the document. After reading, if the tenant agrees with its contents and has no question they should be given instructions to sign.

3. Sign and Attach

After signing, the addendum will be attached to the lease and be made part of it. Any violation of the terms of the addendum will effectively be a violation of the lease.

Refusing to Sign

If a tenant refuses to sign a lease addendum then the lease agreement will be held to its original terms. For example, if a tenant does not sign a pet addendum, the tenant will not be able to have pets on the property.

Breaking an Addendum

The rules of an addendum should be respected in the same manner as of a lease. If a tenant or landlord becomes in default to an addendum it can be a breakable offense. Meaning that a tenant can be evicted from their dwelling if they don’t abide by the addendum. Likewise, a tenant can part ways with their lease and not be subject to fees or rent payments if their landlord fails to uphold an addendum.
