At a glance

• Return deadline: 21 days after vacating
• Measured from: Termination of the tenancy and receipt of the tenant's mailing address or delivery instructions
• Penalty for late or wrongful withholding: no statutory multiplier
• Deposit cap: No statutory cap under state law (a landlord may charge whatever amount the lease specifies).
• Small claims cap: $12,000

Who this covers — and who it does not

This page covers residential security deposits in South Dakota, where a landlord has kept some or all of a deposit after a tenancy ends.

It does not cover:

• Commercial leases
• Deposits held in an escrow account or with a third party
• Disputes about damage charges in an ongoing (not ended) tenancy
• Any state other than South Dakota

Lease terms and local ordinances can change what applies. Where a city has its own deposit rules, those may differ from the state statute below.

What the statute actually says

Penalties

• No statutory penalty beyond returning the deposit.

  A landlord who fails to comply with this section forfeits all rights to withhold any portion of the deposit. Separately, a BAD FAITH retention (or bad-faith failure to provide the written statement or itemized accounting) subjects the landlord to punitive damages not to exceed $200. There is no statutory multiplier.

• A flat penalty of $200.

  A bad-faith retention, or bad-faith failure to provide the written statement or itemized accounting, subjects the landlord to punitive damages not to exceed $200. Bad faith is a separate finding.

Working out your own deadline

The clock does not start on the day you decided to leave. In South Dakota it starts Termination of the tenancy and receipt of the tenant's mailing address or delivery instructions — for most leases that is the date you hand back the keys, not the date your notice period began.

1. Find the date you vacated and returned the keys. Write it down; everything else depends on it.
2. Add 21 calendar days. Count calendar days, not business days.
3. If the landlord has provided a forwarding address, check the statute for whether the deadline is shortened — in some states it is.
4. Note the date the deadline falls on. If the deposit has not arrived by then, the clock for the penalty starts running.

When you need a lawyer instead of a tool

A self-help letter is the right starting point for a single deposit you can document. Get legal help if:

• You have received an eviction notice — the timeline is now court-driven
• The dispute involves discrimination, unsafe conditions or retaliation
• The amount in dispute exceeds $12,000
• Your landlord has filed anything in court already

Local legal aid organisations and tenant unions offer free help for qualifying cases. They are independent of this site — we list them because they are the right place to go, not because they link here.
