It provides clear language to modify the original lease term, update rent or other payments, and confirm the parties' continuing rights and obligations. Use this document when the parties to an existing lease agree to continue the tenancy beyond the original expiration date.

The template also confirms that all other terms of the original lease remain in force except as expressly modified here.

What is a Extension of Lease Agreement?

An Extension of Lease Agreement is a written amendment that lengthens the term of an existing lease without creating a brand-new lease. Its legal purpose is to modify the original lease’s duration and any related terms agreed by both parties, and it is used by landlords and tenants who want to continue the tenancy under revised timing or conditions.

Key Components

A legally effective Extension of Lease Agreement must include the following elements:

Reference to the original lease (date and parties) so the extension clearly links to the prior agreement
New term start and end dates, and whether the extension is fixed-term or month-to-month
Rent amount and payment schedule for the extended period, including any increases or adjustments
Security deposit treatment and any changes to deposit amount or application
Continuation or modification of existing rights and obligations (maintenance, utilities, subleasing, pets)
Default, notice, and termination provisions that apply during the extended term
Signatures and dates for all parties and a statement that the remainder of the original lease remains in effect

When to Use This Template

Tenant needs more time beyond the lease expiration while searching for new housing and the landlord agrees to keep the tenancy going.
Landlord wants to retain a reliable tenant and offers an extended term, possibly with modest rent adjustments, rather than reletting the unit.
Both parties agree to extend the lease to cover a specific period during renovations, temporary job changes, or academic terms.
Property is under consideration for sale or refinance and the owner wants to document continued occupancy while the transaction proceeds.
Parties want to preserve original lease terms but update only the end date and any negotiated rent changes without drafting a new full lease.

Frequently Asked Questions

What is a lease extension?

A lease extension is a signed amendment that lengthens the existing lease term. It keeps the original lease in effect while changing the dates and any agreed modifications.

Can a landlord refuse to extend a lease?

Yes; landlords generally can refuse to extend unless the lease or local law gives the tenant a right to renew. If both parties want an extension, they must mutually agree and sign the amendment.

Do I need a lawyer to extend a lease?

You don't always need a lawyer, especially for simple extensions that only change dates and rent, but consulting an attorney is wise for complex changes, commercial leases, or when significant legal rights are affected. A lawyer can ensure the amendment is enforceable and complies with local landlord-tenant laws.

How do you extend a lease agreement?

Draft an extension document that references the original lease, states the new term and any changes (rent, deposit, rules), and have both parties sign and date it. Keep a copy with the original lease and deliver signed copies to all parties.
