What information should be included in a rent increase notice?

The Short Answer

A rent increase notice should clearly identify the tenant, the rental property, the current rent, the proposed new rent, when the new amount starts, when and how the notice was delivered, and who the tenant can contact with questions. It should also be written in a way that matches the lease terms and current state or local notice requirements, especially because rent increase rules can vary by location and may change over time.

Why This Matters

Rent increase notices are one of the most common points of tension between rental owners and tenants. Owners need to adjust rent to reflect rising operating costs, insurance, taxes, maintenance, market conditions, or investment goals. Tenants need enough time and clear information to decide whether they can afford the new rent, plan their budget, ask questions, or consider moving.

When a notice is incomplete or unclear, practical problems follow. A tenant may not know whether the increase applies to the base rent only or includes parking, storage, utilities, pet rent, or other monthly charges. They may misunderstand the effective date and pay the old amount, creating an avoidable dispute. An owner may believe the notice period has started, while the tenant argues the notice was not properly delivered or did not contain enough information.

For Washington rental owners and property managers, this is especially important because landlord-tenant requirements can depend on the property type, lease structure, local rules, and the date the notice is served. Some cities may have additional tenant protections, notice language, or timing requirements beyond statewide standards. A notice that feels “standard” may not be appropriate for every property.

A well-prepared rent increase notice does three things: it communicates the change clearly, gives the tenant a usable timeline, and creates a written record for both sides. That record can be important if there is later disagreement about what was sent, when it was sent, and what rent amount was expected.

Practical Guide

1. Identify the tenant and rental property clearly

Start with the basics so there is no question about who the notice applies to. Include:

• Full name of each tenant listed on the rental agreement, if practical
• Rental property address
• Unit number, if applicable
• City and state
• Date the notice is prepared or served

Example:

To: Jordan Smith and Taylor Smith
Rental Property: 1234 Evergreen Avenue, Unit B, Tacoma, WA 984XX
Notice Date: March 1, 2026

This matters most for owners with multiple units, duplexes, accessory dwelling units, or tenants with similar names. A vague notice can create confusion and weaken the paper trail.

2. State the current rent and the new rent

The notice should spell out the existing rent amount and the new rent amount in plain language. Avoid only stating the increase amount, because tenants need to know the total monthly rent they are expected to pay.

Clear wording might look like:

Your current monthly rent is $1,850. Beginning on the effective date stated below, your new monthly rent will be $1,975.

If the increase affects only base rent, say that. If other recurring charges are changing too, list them separately. For example:

• Base rent: increasing from $1,850 to $1,975
• Parking: no change, remains $75 per month
• Pet rent: no change, remains $35 per month
• Utility billing: no change, billed separately under the rental agreement

This level of detail helps avoid disputes over whether the “rent increase” includes other monthly charges.

3. Give a specific effective date

Do not say only “next month” or “after the notice period.” Use a specific date.

Example:

The new monthly rent amount will take effect on July 1, 2026.

The effective date should match the lease terms and the required notice period for the property’s location. For month-to-month tenancies, the timing rules may differ from fixed-term leases. For fixed-term leases, rent often cannot be changed during the lease term unless the lease allows it or both parties agree. Owners should verify the current requirements before serving the notice.

Tenants should compare the effective date with the date they received the notice. If the timing seems unclear, they should ask for clarification in writing.

4. Include delivery details and keep proof

The notice should show when it was delivered and, ideally, how it was delivered. Common delivery methods may include personal delivery, mail, posting where allowed, or electronic delivery if permitted by the rental agreement and applicable rules.

A rent increase notice should include:

• Date of delivery or service
• Method of delivery
• Name of the person or office sending the notice
• Contact information for follow-up questions

Owners and property managers should keep a copy of the notice and any supporting proof, such as a mailing receipt, delivery log, email record, or tenant acknowledgment where appropriate. Tenants should keep their own copy as well.

The key point is not just writing the notice, but being able to show what was sent and when.

5. Make the notice easy to understand

A rent increase notice should be direct, organized, and free of unnecessary language. Tenants should be able to quickly answer:

• What is changing?
• How much will I owe?
• When does it start?
• Who do I contact if I have questions?

A simple structure works best:

1. Heading: “Notice of Rent Increase”
2. Tenant and property information
3. Current rent
4. New rent
5. Effective date
6. Delivery date and method
7. Contact information
8. Any required local or lease-specific language

Avoid mixing a rent increase with unrelated complaints, maintenance reminders, or informal comments. If other lease changes are being proposed, those may require separate handling.

6. Check state, local, and lease requirements before sending

Before issuing a rent increase notice, owners should review:

• The current rental agreement
• State landlord-tenant rules
• Local city or county requirements
• Any special rules for subsidized, affordable, or regulated housing
• Any limits on rent increases or required disclosures that may apply

Washington rental housing rules can change, and some local jurisdictions may add requirements. General templates are useful starting points, but they should be checked against the current rules for the exact property location.

Tenants should also review their lease and local tenant resources if they are unsure whether a notice is complete or timely. The goal is to understand the notice, not ignore it.

Common Mistakes to Avoid

• Leaving out the effective date: A notice that does not clearly say when the new rent begins can lead to payment disputes.

• Only listing the increase amount: Saying “rent will increase by $100” is less clear than stating both the current rent and the new total rent.

• Using the wrong notice period: Timing requirements can vary by location, lease type, and housing category. Always verify before serving the notice.

• Changing multiple terms without clarity: If rent, parking, utilities, fees, or lease terms are all changing, separate and explain each item clearly.

Key Takeaways

• A rent increase notice should identify the tenant, property, current rent, new rent, effective date, delivery date, and contact person.

• Clear written notices reduce confusion and create a record for both rental owners and tenants.

• The new total rent should be stated plainly, not just the amount of the increase.

• Owners should check the lease and current state or local requirements before serving the notice.

• Tenants should keep a copy of the notice and ask written questions if the amount, date, or terms are unclear.
