FAQs
A lease extension agreement, or lease renewal, allows a landlord and tenant to extend a lease agreement beyond its end date while keeping the remaining terms and conditions intact unless amended. The landlord may choose to adjust the monthly rent based on economic conditions.
To extend your lease, first gather the original lease to check its end date. Then, discuss your intentions with the other party, send a lease extension addendum detailing any changes, and finally, both parties must sign the addendum to formalize the extension.
A lease extension addendum should include the names of the landlord and tenant, property address, effective date of the extension, new end date, rent amount during the extension, and signatures from both parties. It may also disclose consequences for breaking the lease extension.
A lease extension is a continuation of the original lease agreement, maintaining the existing terms, while a lease renewal is a new lease agreement that begins after the original lease has expired. Extensions allow for minor changes, whereas renewals may introduce new terms.
If a tenant remains in the rental unit after the lease expires without a lease extension, they become a holdover tenant, and the lease converts to a month-to-month tenancy. In this case, landlords cannot renegotiate rent, and tenants may lose certain rights.
Using a lease extension addendum is beneficial when both parties wish to maintain the original lease terms with minor adjustments, avoiding the administrative work of drafting a new lease. It is particularly useful for tenants needing additional time without committing to a full new lease term.
Yes, during a lease extension, either party can negotiate the rent amount based on current economic conditions. This is a common practice, especially if the extension is for a shorter period.
Without a lease extension addendum, if a tenant stays after the lease ends, they become a holdover tenant, and the lease automatically converts to a month-to-month agreement. This limits the ability to renegotiate rent and certain lease provisions.
