Security deposit return deadline in South Dakota

When the clock starts

Most states run the deadline from the later of two events: the tenancy ending and the tenant actually handing back possession. A tenant who stops paying in March but leaves in May usually triggers the clock in May, not March. Several states add a third condition — the tenant supplying a forwarding address in writing — and in those states the deadline does not begin until that arrives.

For South Dakota specifically: 21 days to return or give a written statement of reasons. A full itemised accounting is due within 45 days, but only on the tenant's request. Bad faith carries punitive damages up to $200.

What has to be in the letter

Returning the money is only half of it. Nearly every state that sets a deadline also requires an itemised statementwhen anything is withheld, and the usual penalty for a missing or late statement is not a fine — it is forfeiting the right to withhold anything at all. A landlord with $900 of genuine damage and no timely itemisation frequently recovers nothing.

Include, at minimum:

• Each deduction on its own line, described specifically — “replace broken bedroom blind, $85”, not “repairs, $300”.
• Invoices, receipts or written estimates. Some states require them outright; the rest reward you for having them.
• The arithmetic: deposit held, deductions totalled, refund enclosed.
• Proof of delivery, sent inside the deadline — first-class mail to the forwarding address, certified where the state asks for it.

Normal wear and tear is not damage

The single most common reason a deduction fails is that it was really wear and tear. Carpet flattened by four years of walking, paint faded by sunlight, and scuffs behind furniture are the cost of letting property, not the tenant’s bill. Damage is something beyond ordinary use: a burn, a hole, a pet stain through to the underlay, a missing door. If the item would have needed replacing at the end of its useful life anyway, charging the full replacement cost to one tenant rarely survives scrutiny.

How this compares

Deadlines across the United States run from 14 days to 60, and two states set none at all. South Dakota sits at 21 days. See every state side by side.
