These laws ensure that tenants’ deposits are handled fairly and transparently, protecting both landlords and tenants. This guide will help you navigate South Dakota’s security deposit laws, including the maximum cap, return timeline, and allowable deductions.

Permitting, Zoning, or Statutory Basis

South Dakota’s security deposit laws are primarily set forth in the Rental Housing Act (SDCL 31-20-1, et seq.). This act provides detailed guidelines on the handling of security deposits in rental properties. Additionally, landlords must comply with local municipal ordinances that may further specify requirements.

Lease Clauses, Notice Periods, and Timing Requirements

Lease Clauses

Lease agreements must include a clause regarding security deposits. This clause should specify the amount of the deposit, its purpose, and how it will be returned to the tenant upon move-out. Landlords must also outline any conditions under which deductions may be made from the deposit.

Notice Periods

Landlords must provide tenants with a written notice of any deductions made from the security deposit within 30 days of making such deductions. This notice must itemize all deductions and explain the reasons for each.

Timing Requirements

Security deposits must be returned to tenants within 30 days of the tenant’s move-out, unless there are deductions authorized by law. If deductions are made, the remaining balance must still be returned within 30 days of the notice of deductions.
