How long does a landlord have to return a security deposit in Idaho?
In Idaho, the deadline is 21 days (or 30 days if stated in lease). That clock runs from move-out and the return of possession, not from the end of the lease.
Idaho law sets the maximum deposit at No statutory limit.
Missing the deadline has teeth. Across states, remedies range from losing the right to any deduction to penalty damages plus the tenant's attorney's fees. The itemized deduction statement has to arrive inside the same window to preserve any deduction at all.
