Lease Extension Agreement (Free Fillable PDF)
A lease extension agreement is a short document that pushes back the end date of an existing lease while keeping all of its other terms. When it renews the lease on the same terms, some landlords call it a lease renewal agreement. Instead of writing a whole new lease, the landlord and tenant sign one page that names the original lease, the new end date, and anything that changes, such as the rent.

Lease extension vs lease renewal
| Lease extension | Lease renewal | |
|---|---|---|
| What it is | An add-on that moves the end date of the current lease | A new lease (or a renewal agreement) for a new term |
| Paperwork | One page signed by both sides | A full new lease, or a renewal offer the tenant accepts |
| Other terms | Stay exactly as in the original lease | Can be rewritten |
| Best for | Short or simple extensions, often a few months | A new full term, or when many terms change |
People use the two words loosely, and the line between them is not the same everywhere. What matters is what the signed document says. If you want to offer a full new term, the lease renewal letter is the better starting point.
When to use a lease extension
- The tenant needs a few more months, for example until a house purchase closes or a school year ends.
- You want to line up the lease end with a better month to find the next tenant.
- Both of you are happy with the lease as it is and only the date needs to change.
- You want a fixed end date instead of letting the lease roll into month-to-month.
If the lease simply ends and the tenant stays, what happens next depends on the lease and state law. In many places the tenancy continues month to month on the same terms, but do not assume it. A signed extension removes the doubt.
What to include
| Item | Why it matters |
|---|---|
| Names of the landlord and every tenant | Everyone on the original lease should sign the extension |
| Rental address and unit | Ties the extension to the right property |
| Date of the original lease | Shows exactly which lease is being extended |
| Current and new end dates | The main point of the agreement |
| Rent during the extension | Same amount, or the new amount and the date it starts |
| Security deposit | Whether it stays the same or changes |
| Other changes | Anything else that is different; write “None” if nothing |
| “All other terms stay the same” | Keeps the rest of the original lease in force |
| Signatures and dates | From the landlord and all tenants |
Changing the rent in an extension
An extension is a natural time to adjust the rent, but rent increase rules still apply. Many states and some cities set how much written notice you must give before rent goes up, and some places limit how much rent can rise each year. Check your state and local rules first, then put the new amount and the start date in the agreement. If you prefer to send the increase as its own notice, use the rent increase letter.
If the rent changes, update your records from the start date so the ledger shows the new amount. The tenant ledger has a line for each month’s charge.
How to extend a lease, step by step
- Talk early. Ask the tenant about their plans 60 to 90 days before the lease ends, or earlier if your lease or local law requires notice.
- Agree on the new end date and the rent, plus any other change.
- Fill in the extension agreement and check the names, address and dates against the original lease.
- Everyone signs: the landlord and every adult tenant on the lease. Each keeps a copy.
- Attach it to the original lease and update your ledger and calendar.
Example
| Field | Example |
|---|---|
| Original lease | June 1, 2026 to May 31, 2027 |
| New end date | August 31, 2027 |
| Rent | Stays the same at $1,450 per month |
| Security deposit | Stays the same |
| Other changes | None |
This tenant needed three more months while waiting for a new home. The rest of the lease, including late fees, pets and utilities, stays exactly as it was.
Lease, notice and rent rules differ by state and city. For anything complex, talk to a local attorney.

Frequently asked questions
What is a lease extension agreement?
A short written agreement, signed by the landlord and tenant, that moves the end date of an existing lease. The other terms of the original lease stay the same unless the agreement says otherwise.
Is a lease extension the same as a lease renewal?
Not exactly. An extension usually keeps the original lease and changes the end date. A renewal usually means a new lease or a new term, where more terms can change. The signed document is what counts.
Can I raise the rent in a lease extension?
Often yes, if the tenant agrees and you follow your state and local rules on rent increases and notice. Write the new amount and the date it starts in the agreement.
Do all tenants need to sign the extension?
Yes. Every adult tenant who signed the original lease should sign the extension, along with the landlord or agent.
What happens if the lease ends and nobody signs anything?
It depends on the lease and state law. In many places the tenancy continues month to month on the same terms, but rules vary. A signed extension or renewal avoids the question.
