South Dakota Security Deposit Deadline 2026: Landlords Now Have 21 Days to Return the Deposit

The change moves the deadline from 2 weeks to 21 days, a week longer than before.

That extra week gives a landlord more realistic time to inspect a unit, calculate any deductions, and prepare the required written statement, particularly for a turnover that involves repairs or cleaning that can't be assessed the same day a tenant moves out.

The deadline runs from the termination of the tenancy and the landlord's receipt of the tenant's mailing address or delivery instructions, not from the move-out date alone.

A tenant who moves out but never gives the landlord a forwarding address hasn't started this clock; a landlord facing that situation isn't yet in violation simply because 21 days have passed since the unit was vacated, since the second condition hasn't been met.

The landlord has to provide a written statement showing the specific reason for withholding the deposit at the time of the return.

A landlord who sends back a partial deposit with no explanation, or a vague note like "damages," hasn't met this requirement; the statement has to specifically identify why the amount was withheld.

Beyond the written statement accompanying a withholding, a tenant can separately request a full itemized accounting, which the landlord has to provide within 45 days of the tenancy's termination.

That's a distinct obligation from the initial written statement; a tenant who wants more detail than a brief reason statement provides has 45 days from the end of the tenancy to ask for it, and the landlord has to comply within that same window.

Permitted deductions are limited to unpaid rent, other contractual charges, or restoring the premises to its original condition, excluding normal wear and tear.

A landlord who tries to charge a tenant for a worn carpet or faded paint from years of ordinary use is deducting for something this statute specifically excludes; the deduction has to tie to actual unpaid charges or damage beyond what normal living in the unit would cause.

A landlord who retains a deposit in bad faith, or who fails to provide the required written statement or itemized accounting, faces punitive damages of up to $200 and forfeits any right to withhold the deposit.

That forfeiture provision is the sharper half of the penalty; a landlord who misses the paperwork requirement doesn't just risk a $200 penalty, they can lose the entire ability to keep any portion of the deposit, even an amount that was otherwise legitimately owed.

The punitive damages provision is tied to bad faith retention, not simply any late return or minor paperwork lapse.

A landlord who misses the 21-day deadline by a few days due to a genuine administrative delay is in a different position than one who deliberately withholds a deposit with no intention of returning it or explaining why; the specific facts of the delay matter to how this standard applies.

This change specifically extended the time period from 2 weeks to 21 days; it didn't alter the written-statement requirement, the itemized-accounting right, the permitted deduction categories, or the penalty structure that already existed.

A landlord already familiar with South Dakota's deposit-return framework before this change mainly needs to update the specific number of days; the rest of the compliance obligations carry forward unchanged.

The enrolled bill text doesn't contain its own effective-date clause, so the change took effect under South Dakota's standard statutory default of July 1, 2026, the start of the state's next general effective-date cycle after enactment.

A landlord auditing compliance dates should treat July 1, 2026, as the operative date for this extended deadline, consistent with how South Dakota's standard legislative effective-date rule applies when a bill doesn't specify its own date.

Since the deadline itself changed numerically, from 14 days to 21, any lease template, tenant-facing notice, or internal move-out checklist that cites the old 2-week figure needs a direct update.

[Cite: SDCL 43-32-24, as amended by S.D. Session Laws 2026, ch. 179]

A property manager relying on an older template that still references a 14-day return window risks giving tenants inaccurate information about their own rights, even though the actual compliance deadline for the landlord has become more generous.

The practical starting point is updating every lease document, move-out notice, and internal deposit-processing checklist to reflect the 21-day deadline rather than the old 2-week figure.

For any deposit withholding, building a standard practice of issuing the written reason statement at the same time the partial or full deposit is returned, rather than as a follow-up step, keeps the process aligned with what this statute specifically requires.
