Free Rent Increase (Rent Change) Addendum Template

A rent increase (rent change) addendum is a short document that updates the rent amount on an existing lease. Once both parties sign, the new figure replaces the old one, and the rest of the lease continues unchanged.

Landlords use it at renewal, after a fixed term ends, or whenever a lease allows an adjustment. Tenants sign it to confirm they understand the new amount and when it starts.

The same document handles a decrease. A tenant may take on yard work. A unit may lose an amenity. Or a landlord may negotiate to keep someone reliable. That is why rent change often appears beside rent increase in the title.

Because it attaches to the lease, nothing else moves. Term dates, deposit amounts, and house rules all stay exactly where they were.

Reach for this document any time the monthly amount shifts during or between lease terms.

Because timing varies so much, it helps to name the situations directly.

Renewal is the most common trigger. When a one-year lease ends and the tenant stays, the addendum records the new rate without a brand-new agreement.

Month-to-month arrangements are another. Rent there can move more freely, so a written record keeps each adjustment documented rather than verbal.

Cost pass-throughs also come up. Utilities may shift from landlord-paid to tenant-paid, or a parking space may get added. Either way, the total owed each month changes and belongs in writing.

Finally, use one after a negotiation. Suppose a tenant asks for a smaller increase in exchange for a longer term. A single document then captures both halves of that deal.

Keep it short and unambiguous. Two numbers and a date do most of the work here.

Length is not a virtue in this document. A tenant who can read the whole page in a minute is far more likely to sign it promptly.

Identifying Information

• Landlord and tenant names
• Property address and unit
• Original lease date and term
• Date this document is signed

Current and New Rent

State both figures side by side so the change is obvious:

• The current monthly rent
• The new monthly rent
• The dollar or percentage difference, if you want it spelled out

Effective Date

Name the exact date the new amount is first due. Also confirm which payment is the first at the new rate, since a mid-month start confuses almost everyone.

Payment Details

Repeat how and where rent is paid, especially if that is changing too. Include the due day, accepted methods, and any late fee terms already in the lease.

Everything Else Stays the Same

Add a line confirming that all other lease terms remain in force. Without it, a tenant may wonder whether the original agreement still holds.

Signatures

Leave space for both parties to sign and date. A rent increase (rent change) addendum only works once both sides have actually signed it.

Both documents can raise rent, yet they do different jobs.

A renewal starts a fresh term. It restates the dates, the rent, and often every other term. The tenant therefore signs what amounts to a new agreement.

An addendum changes one number and leaves the rest alone. Nothing about the term, the deposit, or the house rules moves.

Choose the addendum when the tenancy continues and only the rent shifts. Choose a renewal when the term itself is ending and you want a clean restart.

There is also a practical difference. Tenants read a one-page rent change far more carefully than a six-page renewal. That usually makes the conversation shorter and clearer.

If both apply, run them in order. Sign the renewal first, then attach the rent change if the figure moves again mid-term.

How much warning you owe a tenant depends on where the property sits and on what the lease already says. Check your state’s official website, and read your own lease before you pick a date.

Consent matters just as much. During a fixed term, rent generally cannot change unless the lease permits it or the tenant agrees in writing. That written agreement is exactly what this document provides.

If a tenant declines to sign, you still have options at the end of the term. However, mid-term changes without agreement tend to breed disputes, so secure the signature first.

Rent-controlled and rent-stabilized units can carry extra rules. A local housing agency or a landlord-tenant attorney can tell you what governs your building.

Presentation matters more than most landlords expect. Send the document in writing, keep the tone plain, and give the tenant room to read it.

Therefore, treat delivery as part of the job rather than an afterthought.

A short cover note helps. Explain that rent is changing, state the new amount and start date, and point to the signature line. Avoid burying the figure inside a paragraph.

Keep proof of delivery. An email acknowledgment, a signed receipt, or a certified mailing all create a record you can rely on later.

Once signed, file it with the original lease and update your payment records. Also tell whoever handles your bookkeeping, since a stale figure in an accounting system creates late-fee disputes that nobody wants.
