Security deposit return deadline in Idaho

An Idaho landlord has 21 days after the tenancy ends to return a security deposit, or up to 30 days if you agreed to that in writing.

Deadline
21 days (up to 30 if agreed in writing)
What the landlord must send
A partial refund must come with a signed statement itemizing amounts kept, their purpose, and a detailed list of expenditures.
If the landlord gets it wrong
The statute sets no multiple; the tenant can sue for the amount wrongfully kept.

A landlord may not keep any of the deposit for normal wear and tear.

The law

Idaho Code § 6-321. Read the statute.

Checked against the statute in October 2026. Laws change, so confirm the current rule before you rely on it.

What to do next

If the deadline has passed, or the landlord kept money without a proper list, put your request in writing. Ask for the deposit back by a specific date, and keep a copy. The free first letter in the Deposit Demand Letters kit does this for Idaho, and the deadline calculator works out your exact date from your move-out day.
