South Dakota Lease Amendment

This Lease Amendment 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.

Security deposits in South Dakota

Any money that secures performance of a residential lease is a security deposit, and a South Dakota landlord may not demand or receive more than one month’s rent — unless the parties agree to a larger deposit because special conditions pose a danger to maintenance of the premises (SDCL §43-32-6.1).

21-day deadline — Within 21 days after the tenancy ends and the landlord receives the tenant’s mailing address or delivery instructions, the landlord must return the deposit or give a written statement of the specific reasons for withholding any part of it (§43-32-24). The window was two weeks before a 2026 amendment (SL 2026, ch 179).
Allowed deductions — Only amounts reasonably needed to cover unpaid rent and other funds due under the lease, and to restore the premises to their move-in condition, ordinary wear and tear excepted (§43-32-24).
Itemized accounting — On the tenant’s request, the landlord must provide an itemized accounting of any amount withheld within 45 days after the tenancy ends (§43-32-24).
Penalty — A landlord who misses these requirements forfeits the right to withhold any of the deposit, and bad-faith retention or failure to provide the statement can add punitive damages of up to $200 (§43-32-24).

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).

South Dakota Lease Amendment FAQs

How much can a landlord charge for a security deposit in South Dakota?

No more than one month’s rent, unless the landlord and tenant agree to a larger deposit because special conditions pose a danger to the premises (SDCL §43-32-6.1).

How long does a landlord have to return a security deposit in South Dakota?

21 days after the tenancy ends and the landlord receives the tenant’s mailing address, returning the deposit or a written statement of reasons for withholding. The deadline was two weeks until a 2026 amendment. An itemized accounting is due within 45 days on request, and missing the rules forfeits the right to withhold (§43-32-24).
