South Dakota Month-to-Month Lease Agreement

Last Updated: May 27, 2025 by Roberto Valenzuela

A South Dakota month-to-month rental agreement is a contract (not necessarily in writing) for a tenant to rent property from a landlord, one month at a time, in exchange for a fee (“rent”). The agreement renews monthly, until either party gives proper notice to end it.

Basics of a South Dakota Month-to-Month Rental Agreement

In South Dakota, a landlord and tenant create a month-to-month lease by agreeing to rent a property according to acceptable terms. Written agreements are clearer and more reliable in case of disagreement, but month-to-month oral (unwritten) leases are legal.

Parties under a month-to-month lease have full rights under South Dakota landlord-tenant law. The tenant must use the property in a responsible way and pay rent on time. The landlord must ensure the tenant’s quiet enjoyment of the property. This includes keeping critical features of the property in good working condition.

The main difference between a month-to-month lease and a fixed-term lease is that month-to-month leases can be terminated (with proper notice) by either party, for any reason, without penalty. Landlords also can usually modify terms from one month to the next, again with proper notice.
