About the United States Lease Extension Agreement

There is no federal lease-extension statute. State landlord-tenant laws govern lease modifications, rent increases, and termination notice requirements. This baseline extension template covers the essential elements (parties, premises, term, rent, deposit, other terms) but should be reviewed against applicable state and local law. Rent-controlled jurisdictions (parts of California, New York, New Jersey, Oregon, Washington, and Maryland) have additional requirements.

United States Lease Extension Agreement Framework

• No federal lease-extension statute exists
• State law varies on rent increase notice (typically 30-90 days)
• Rent-controlled jurisdictions may have specific renewal/extension rules
• Security deposit handling continues under original state law
• Form: signed writing by both parties is generally sufficient

What This Document Does

• Identifies both parties and the original lease being extended
• States the new extension term start and end dates
• Specifies rent during the extension (and any changes)
• Addresses security deposit treatment
• Confirms all other original lease terms remain in effect

Notice Requirements and Best Practices

State landlord-tenant laws govern lease extensions. Best practice is to communicate extension intentions 30-60 days before the original lease end date and execute the extension at least 30 days before the original ends. Rent increases during the extension may require advance notice under state law (typically 30-90 days). Rent-controlled jurisdictions have additional rules. Verify applicable state and local law before executing.

Lease Extension vs. Renewal vs. Amendment vs. Holdover

These four terms get used interchangeably, but they describe different legal situations. Picking the wrong one is the most common reason an “extension” ends up disputed. The short version: an extension keeps the same lease and adds time; a renewal is a new lease; an amendment changes terms without necessarily adding time; a holdover is what happens when the term ends and nobody signed anything.

Some states attach real consequences to the label. Florida, for example, provides that “a renewal of an existing rental agreement shall be considered a new rental agreement, and any security deposit carried forward shall be considered a new security deposit” (Fla. Stat. § 83.49(6)). If you want the deposit and every other term simply to continue, say so in the extension itself. For mid-term changes that don’t add time, use a lease amendment; for a plain rolling tenancy, see the month-to-month rental agreement.

What Should a Lease Extension Agreement Include?

A lease extension agreement template needs just enough detail to identify the original lease and state exactly what changes. The form above prints each of these as its own numbered section:

1. The parties. Landlord (or management company) and every tenant, with names that match the original lease. If a tenant is leaving or joining, that is a change of parties, and a renewal or an amendment signed by everyone is the cleaner route.
2. The property. Full street address with unit number, so the extension can’t be read as covering a different unit.
3. The original lease. Its start date, end date, and the date it was signed. This ties the extension to one specific contract.
4. The extension term. A new start date (normally the day after the original end date) and a fixed new end date. Avoid open-ended wording such as “until further notice”; if you want an open-ended tenancy, use a month-to-month agreement instead.
5. Rent during the extension. The monthly amount, the due date, and whether it is the same, higher, or lower than before, plus any change to late fees, parking, pet rent, or utilities.
6. Security deposit. Whether the existing deposit carries over unchanged, is topped up, or is partly refunded. Spell it out; don’t leave it to inference.
7. Everything else. A statement that all other terms of the original lease remain in full force, or a list of the specific terms that change.
8. Signatures and dates. Every adult tenant on the lease and the landlord or authorized agent. If the original lease has a guarantor or co-signer, ask them to sign as well; whether a guaranty covers an extended term depends on the guaranty’s own wording.

When Should You Use a Lease Extension Agreement?

An extension is the right tool when both sides are satisfied and the change is mostly about time. Typical situations:

• The tenant needs a few extra months: a home purchase is closing later than planned, a job transfer is pending, or a new build isn’t finished.
• The landlord wants to shift the lease-end date into a stronger rental season, or to line up with a planned sale or renovation.
• Aligning with a school year or academic calendar, common in student and faculty housing.
• Buying time while a renewal is negotiated: a short extension keeps the tenancy on a written footing instead of drifting into a holdover.
• A good tenant, unchanged terms: when nothing but the end date needs to change, an extension avoids re-papering the whole lease.

When not to use one: if you are changing several terms, adding or removing a tenant, or the unit is covered by a rent-stabilization program with its own renewal-lease rules, a new lease or the program’s required renewal form is usually the correct document. See the lease renewal agreement and lease renewal offer, and for New York City rent-stabilized units the rent-stabilized renewal offer.

How to Extend a Lease, Step by Step

1. Re-read the original lease. Look for a renewal or extension option, an automatic-renewal clause, a notice-to-vacate deadline, and any rule about how the lease may be modified (many leases require changes to be in writing and signed by all parties).
2. Check your state and city rules on rent increases and notice, especially if you plan to raise the rent. The verified examples below show how much these differ.
3. Raise it early. Talking 60 to 90 days before the end date leaves room for any statutory notice period and for the tenant to plan.
4. Agree the terms: new end date, rent, deposit treatment, and any other change.
5. Complete the form above and generate the PDF. Review every field with the other party before anyone signs.
6. Sign before the original lease ends. Every tenant and the landlord sign and date the extension; keep a signed copy attached to the original lease.
7. Update your records: lease-end reminders, rent ledger, deposit records, and ask the tenant to update renters insurance dates if the policy is tied to the lease term.

State Rules That Affect a Lease Extension (Verified Examples)

There is no federal lease-extension statute, so the rules come from each state and, in some places, the city. The examples below are quoted or paraphrased from the official statute text. They show the kinds of rules to check; they are not a complete survey. For any state not listed, check that state’s page in the “By state” row at the top of this page or our rent increase laws by state and lease termination laws by state guides.

Writing requirements

California: “An agreement for the leasing for a longer period than one year” is invalid unless it, or a note or memorandum of it, is in writing and subscribed by the party to be charged (Cal. Civ. Code § 1624(a)(3)). Most states have a similar statute of frauds, which is one more reason to put every extension in writing and have both sides sign it.

Rent increases in the extension

• California: for covered units, an owner may not, over any 12-month period, increase the rent “more than 5 percent plus the percentage change in the cost of living, or 10 percent, whichever is lower” (Cal. Civ. Code § 1947.12(a)(1); the section lists exemptions and is set to be repealed January 1, 2030). See California rent increase laws.
• New York: a landlord who intends to offer a renewal with a rent increase of 5 percent or more, or who does not intend to renew, must give written notice of at least 30, 60, or 90 days depending on how long the tenant has occupied the unit or the length of the lease term. If the landlord fails to give timely notice, the tenancy continues under the existing terms until the notice period has expired (N.Y. Real Prop. Law § 226-c). See New York rent increase laws.
• Oregon: outside week-to-week tenancies, a landlord may not raise rent during the first 12 months of the tenancy, must give written notice at least 90 days before the increase takes effect, may raise rent only once in any 12-month period, and is limited by the percentage cap calculated under ORS 90.324 unless an exemption applies (for example, a first certificate of occupancy issued within the last 15 years) (Or. Rev. Stat. § 90.323). See Oregon rent increase laws.

Automatic extension clauses

Wisconsin: a residential lease provision that the lease “shall be automatically renewed or extended” unless notice is given is not enforceable against the tenant unless the landlord, at least 15 but not more than 30 days before the tenant’s notice deadline, gives the tenant written notice calling attention to the automatic renewal or extension provision (Wis. Stat. § 704.15). A signed extension agreement avoids relying on an auto-extend clause at all. See Wisconsin landlord-tenant laws.

If the lease ends and no extension is signed

• California: if the tenant stays after the lease expires and the landlord accepts rent, the parties are presumed to have renewed “on the same terms and for the same time, not exceeding one month when the rent is payable monthly, nor in any case one year” (Cal. Civ. Code § 1945).
• New York: when a tenant whose term was longer than one month holds over, the landlord does not get the option to hold the tenant to a new full term; if the landlord accepts rent for a period after the term expired, the tenancy becomes month-to-month unless the parties agree otherwise (N.Y. Real Prop. Law § 232-c).
• Florida: a tenant who holds over without the landlord’s permission can be removed under § 83.59 and is liable for double the rent due for the holdover period (Fla. Stat. § 83.58). See the Florida lease extension agreement for Florida’s full treatment.

Common Lease Extension Mistakes

• Agreeing verbally. An oral “sure, stay another six months” is hard to prove and, for longer terms, may not be enforceable at all. Sign a written extension.
• Missing a tenant’s signature. Every adult on the original lease should sign. An extension signed by one roommate leaves the others’ status unclear.
• Waiting until after the end date. Once the term has expired, state holdover rules may already have decided what kind of tenancy exists.
• Raising rent without checking notice rules. A rent change agreed in the extension still has to fit any state or local cap or notice rule that applies.
• Leaving the deposit unaddressed. State whether the deposit carries over, increases, or is partly refunded.
• Vague end dates. “Until the house sale closes” invites a dispute. Use a calendar date, and a separate month-to-month agreement if flexibility is the goal.
• Forgetting attached addenda. Pet, parking, and utility addenda tied to the original term should be confirmed or updated in the same extension.

Lease Extension Agreement FAQ

What is a lease extension agreement?

A lease extension agreement is a written addendum, signed by the landlord and every tenant, that moves the end date of an existing lease to a later date. The original lease stays in force, and only the terms the extension names, usually the end date and sometimes the rent, change.

Is a lease extension the same as a lease renewal?

No. An extension continues the existing lease for more time, so the original contract stays in effect. A renewal is a new lease for a new term that replaces the old one. Some states treat them differently; Florida, for example, provides that a renewal of an existing rental agreement is considered a new rental agreement and any security deposit carried forward is considered a new security deposit (Fla. Stat. section 83.49(6)).

Does a lease extension have to be in writing?

It should always be in writing, and for longer extensions it may have to be. California, for example, makes an agreement for leasing for a longer period than one year invalid unless it, or a note or memorandum of it, is in writing and subscribed by the party to be charged (Cal. Civ. Code section 1624(a)(3)). A written, signed extension also removes any dispute about the new end date.

Can a landlord raise the rent in a lease extension?

Yes, if the tenant agrees and the increase complies with state and local law. Some states cap increases or require advance notice. California limits increases on covered units to 5 percent plus the change in the cost of living, or 10 percent, whichever is lower, over any 12-month period (Cal. Civ. Code section 1947.12). Oregon requires 90 days’ written notice and limits increases to once in any 12-month period (ORS 90.323). New York requires 30, 60, or 90 days’ written notice before offering a renewal with an increase of 5 percent or more (N.Y. Real Prop. Law section 226-c).

What happens if the lease ends and no extension is signed?

The fixed term expires on its end date, and state law decides what happens next. In California, if the tenant stays and the landlord accepts rent, the lease is presumed renewed on the same terms for no more than one month when rent is paid monthly (Cal. Civ. Code section 1945). In New York, accepting rent after the term expires creates a month-to-month tenancy unless the parties agree otherwise (N.Y. Real Prop. Law section 232-c). In Florida, a tenant who holds over without permission is liable for double rent for the holdover period (Fla. Stat. section 83.58).

Does the security deposit carry over to the extension?

It can, and the extension should say so. The form above lets you choose whether the existing deposit carries over unchanged, an additional deposit is required, or part of it is refunded. Stating the treatment in the signed extension avoids later disputes about what was held and on what terms.

How long can a lease extension last?

Any length the landlord and tenant agree to, from a few weeks to another full year or more. Keep in mind that longer terms may trigger a writing requirement, and that any rent change must still follow the state or local rules that apply to the unit.

Can a lease extend automatically?

Only if the lease contains an automatic renewal or extension clause, and some states restrict those clauses. In Wisconsin, an automatic renewal or extension provision in a residential lease is not enforceable against the tenant unless the landlord gives written notice calling attention to it at least 15 but not more than 30 days before the tenant’s notice deadline (Wis. Stat. section 704.15). A signed extension agreement avoids relying on such a clause.

Who needs to sign a lease extension agreement?

The landlord or authorized agent and every tenant who signed the original lease. If the original lease has a guarantor or co-signer, ask them to sign too, because whether a guaranty covers an extended term depends on the guaranty’s own wording.

Can I use this lease extension agreement template in any state?

Yes. It is a national template that covers the elements every extension needs: parties, property, original lease, new term, rent, deposit, other terms, and signatures. State and local rules on rent increases, notice, and holdovers still apply, so check your state’s page in the By state row at the top of this page before you sign.
