South Dakota Lease Extension Addendum
This Lease Extension Addendum is built with South Dakota as the governing state. These are the South Dakota landlord-tenant rules that most often bear on it, with the statute for each.
South Dakota rules at a glance
| Month-to-month termination | Notice as long as the rental period, up to one monthSDCL §43-32-15 |
|---|---|
| Rent-increase notice | 30 days’ written notice before the end of the month (month-to-month)SDCL §43-32-13 |
| Rent increases | On a month-to-month lease, the landlord may change the rent or other terms by written notice given at least 30 days before the end of the month; the new terms take effect at the end of that month if the tenant stays (§43-32-13). |
Rent, late fees & rent increases
South Dakota has no late-fee statute and no rent control. Unless the lease says otherwise, a hiring of real property is presumed to be for one year (SDCL §43-32-3), and a lease longer than one year must be in writing (§43-32-5).
- Late fees — No statute caps late fees or requires a grace period. A late fee should be written into the lease and be a reasonable estimate of the landlord’s cost of late payment; a fee that operates as a penalty risks being unenforceable.
- Rent increases — On a month-to-month lease, the landlord may change the rent or other terms by written notice given at least 30 days before the end of the month; the new terms take effect at the end of that month if the tenant stays (§43-32-13).
- Tenant’s exit right — A tenant who receives a notice of modification may terminate effective the first day of the next month by giving notice within 15 days of receiving it (§43-32-13).
- Fixed-term leases — Rent on a fixed-term lease can’t be raised mid-term unless the lease allows it. If the tenant stays on after the term and the landlord accepts rent, the lease is presumed renewed on the same terms for the same period, up to one year (§43-32-14).
