A security deposit generally may not exceed one month’s rent, or two months if the landlord accepts special conditions such as a pet (S.D. Codified Laws § 43-32-6.1). If no damage is claimed, unused deposit is generally due within 14 days; if damage is claimed, an itemized notice is generally due within 45 days (§ 43-32-24).
A month-to-month tenancy generally takes notice at least equal to the rental interval (S.D. Codified Laws § 43-32-13).
South Dakota does not prescribe a statewide 24-hour entry statute. Put a reasonable-notice entry clause in the lease. Emergency entry is customary.
A South Dakota rent increase should be in writing. Many landlords use at least the same notice they would use to end a month-to-month tenancy. A month-to-month tenancy generally takes notice at least equal to the rental interval (S.D. Codified Laws § 43-32-13). The lease may require more. Local rent-control rules can cap the amount even when the notice period is met.
