Rental Schedule Addendum

What Is a Rental Schedule Addendum in a Lease Agreement?

A Rental Schedule Addendum is a legally binding document attached to a lease that outlines all rent-related financial terms, such as payment amounts, due dates, accepted payment methods, late fees, and rent increase policies, clarifying and supplementing the main lease agreement.

When renting a property, understanding all payment details is crucial. A Rental Schedule Addendum serves as a detailed supplement to the main lease agreement, specifying the exact terms related to rent payments. It ensures both landlords and tenants clearly understand when rent is due, how it should be paid, fees for late payments, and other important financial terms.

Why Is a Rental Schedule Addendum Important?

While the lease agreement sets broad terms for living in the rental property, the Rental Schedule Addendum focuses solely on the specifics of paying rent. This prevents misunderstandings and disputes by clearly documenting the payment schedule and related conditions in a legally binding format.

Typical Components of a Rental Schedule Addendum

  • Rent Amount and Due Date: Confirms the monthly rent and the exact date it must be paid (e.g., the 1st of each month).

  • Accepted Payment Methods: Details how the rent can be paid, such as checks, online portals, bank transfers (ACH), or other methods preferred by the landlord.

  • Prorated Rent: Explains the calculation of rent if you move in mid-month, ensuring you pay only for the days you occupy the property.

  • Late Fees and Grace Periods: Specifies any grace period before late fees apply (e.g., five days after the due date) and the exact amount of late fees. Note that state laws often regulate maximum allowable late fees. For more on late fees, see our article on Late Payment Fee.

  • Bounced Check Fees (NSF Fees): Lists charges for payments returned due to insufficient funds.

  • Rent Increases: Details how and when rent can be increased, including required advance notice to the tenant.

  • Payment Location: Specifies where or how tenants should submit rent payments to avoid delays.

Example Scenario

Suppose a tenant moves in on the 15th of a month. The addendum will calculate prorated rent based on the property’s monthly rate divided by days, so the tenant only pays for their occupancy period. The document might also specify payments must be made through an online portal and include a four-day grace period before a $50 late fee applies.

Tips for Tenants and Landlords

  • Tenants: Always read the addendum carefully before signing. Confirm you understand payment due dates, fees, and any methods required. Keep a signed copy for your records.

  • Landlords: Use clear and specific language, particularly regarding fees and dates. Ensure compliance with local laws governing late fees and rent increases. Both parties should sign and date the document to validate it.

Frequently Asked Questions

An addendum adds new terms or clarifications at the time of signing the lease, whereas an amendment modifies terms of an existing lease after signing.
