Create a lease addendum
Choose the existing lease, describe the changes and review the addendum before sending.
On this page
Step 1: Choose the existing lease
Open Build a lease addendum and select the correct tenancy. You can also use Docs & E-Sign > Forms > Lease Agreement Addendum > Start addendum. Review the original agreement and the People on the lease shown on the form.
Step 2: Choose what changes
Under What is the addendum for?, choose Lease changes, Pet, Parking, Add a tenant or Early termination. Lease changes lets you answer separate questions for the end date, monthly rent, security deposit and other terms.
Step 3: Enter the dates and terms
For Lease changes, check Original lease agreement date against the signed document. Answer Yes for each change and fill in its fields. Enter When does this addendum take effect? Review the wording, amounts and dates before continuing.
Step 4: Create and review
Choose Create addendum. On Who needs to sign?, use Preview to read the document. Check the people, email addresses, message and When will you sign? Creating the document does not send it.
Step 5: Send and check the result
Review any plan or payment step, then select Send for signature when ready. Follow the request in Docs & E-Sign. After completion, review the signed document, saved lease details and payment schedule.
Choose the right document
Use the addendum to record the intended changes while keeping the original agreement for reference. Lease changes also has Other amendments for custom wording.
A landlord-entity change or new co-signer needs a separate review of the right document. The current addendum choices do not offer a co-signer change or a remove-and-swap tenant flow. Do not substitute Add a tenant for a different change.
Understand the dates
Original lease agreement date identifies the agreement being changed. The form may initially show the lease start date, so check it against the original document. The effective date identifies when the new terms begin. These dates can differ.
Check the saved changes
Supported signed amendments can update Rentari's lease terms and eligible unpaid future rent charges. Review the actual result and any review-required message before making another change. A security-deposit change does not by itself create a new charge.
Other written amendments do not automatically configure every related setting. Check the lease and payment schedule after signing, and preserve the original agreement with its signed addendum.
If you need to stop or correct something
Correct any field error before trying again. Check whether a document or request already exists to avoid duplicates. No email on file means the person cannot be selected for sending.
Use the available document actions for corrections after creation. A completed signature is not undone by changing the form. If you sign on paper, keep the completed copy with the lease and review the account details separately.
Check the result
- The addendum is prepared for review. Its request status shows whether sending and signing have completed.
FAQs
What if my original lease is not in Rentari?
Add the existing tenancy's lease profile and people first, using the actual agreement. Return to the addendum picker and select it. Do not invent another tenancy just to create a document.
Can I change rent and the end date together?
Yes. Choose Lease changes and answer Yes to both questions. Check the new values and the effective date before creating the addendum.
Why is someone missing or unselectable?
Review People on the lease and their saved contact details. No email on file prevents selection for sending. Confirm who needs to sign rather than sending an incomplete party list.
Does Create addendum send it?
No. It prepares the document and opens signature preparation. Review it before the separate Send for signature action.
Does signing update every account setting?
No. Supported amendments can update certain lease terms and unpaid future rent charges, but other changes may need review. Check the saved result, any warnings and the payment schedule.
Can I add, remove or swap anyone on the lease?
The current form offers Add a tenant. It does not provide a general removal, swap or new co-signer option. Review the appropriate document process for those changes.
