What Is a Lease Addendum?
A lease addendum is a document you attach to your original lease to introduce additional provisions. It does not modify the original content, so all the initial clauses remain effective. Once the landlord and tenant sign the addendum, it becomes an integral and legally binding part of the original lease.
Your initial lease should include all key clauses, but due to changes over time, you may need to implement new terms. Addenda can fulfill purposes like recording pet policies and clarifying maintenance duties. You can also use them to introduce minor additions without writing a new lease.
Addendum vs. Amendment
An addendum adds to a lease, while an amendment updates existing lease terms. Read our guide to learn more about the differences between an addendum and an amendment.
Is a Disclosure a Lease Addendum?
It can be, but not all disclosures are lease addenda. With a disclosure, a landlord merely fulfills their legal obligation to inform tenants about specific issues. An addendum adds to the terms of the original lease.
Many states and even local cities require landlords to disclose certain information to tenants. For example, New York City landlords must disclose bedbug history, and Section 83.49 of the Florida Statutes requires that landlords provide a specific disclosure about holding advance rent and security deposits. Federal law mandates that all landlords provide information about lead-based paint for residences built before 1978.
How to Add an Addendum to a Lease
Adding an addendum helps you update your release to contain your most current terms. Learn how to add an addendum to a lease below.
Step 1 – Check the Original Lease
Read over your current lease to see what it says about addenda. Ensure there are no clauses that prohibit addenda or restrict their implementation.
Some leases have clauses that specify conditions under which addenda are permissible, so you must follow these if applicable. For example, you may be limited in the topics you can address and formatting requirements.
Step 2 – Talk to the Tenant
Schedule a meeting with your tenant to discuss the new addition to the lease. Consider both parties’ interests and concerns, working together to reach a consensus on the new terms. An in-person discussion can ensure your tenant understands the new terms you want to implement. They can ask questions and negotiate, and you can work with them to reach a mutual agreement.
Tenants may wonder, “Do I have to sign a lease addendum?” In most cases, they are not legally obligated to do so. All parties must consent to and sign the addendum for it to be valid. Otherwise, it is not enforceable.
Step 3 – Write the Addendum
After discussing the addendum with your tenant and ensuring it’s legally enforceable, you can review how to write a lease agreement addendum. Legal Templates’s guided form ensures you include the following key elements:
- Date: Fill out the date when the addendum was created.
- Parties’ details: Provide the landlord’s and tenant’s names and contact information.
- Original lease date: Specify when the original lease was entered into.
- Property location: Clarify the address to which the addendum will apply.
- Addendum details: State what the addendum is. Give a complete description and provide a reason for the new lease addition. Clearly identify the location of the addendum in the lease to avoid confusion, i.e., “Exhibit A.”
- Clarifying statement: Clarify that all other lease provisions will remain unaffected.
Step 4 – Sign & Execute the Addendum
Let the tenant review the written addendum. If they agree with its contents and have no questions, they should sign their name. You must also sign as the landlord. With both parties’ signatures, the addendum is enforceable.
Attach the addendum to the existing lease. Enforce the addendum’s terms, and refer to the written document if any issues arise.

What Happens If a Party Breaks a Lease Agreement Addendum?
Similar to a lease agreement, addendum rules are legally binding. Failure to comply with an addendum can constitute a breach. In such cases, a tenant may face eviction from the property for non-compliance. Conversely, if a landlord fails to uphold the terms of an addendum, the tenant may be entitled to terminate the lease without penalties or obligations, or may have other legal recourse, such as seeking financial damages.
