What clauses are legally required in every Idaho lease agreement?
Every Idaho lease should identify the landlord/agent and all adult tenants, the property, the rent and due date, and the term. Idaho has few mandatory clauses beyond the deposit-return rule (below). A lease for a term longer than one year must be in writing (§ 9-505).
Idaho security deposit rules — the 21-day return
Idaho Code § 6-321 governs deposits:
- No cap on the deposit amount.
- Return: within 21 days if the lease fixes no time; if the lease specifies a longer period, the deadline is still capped at 30 days. A written itemized statement of deductions is required with any withholding, and failure to provide it forfeits the right to retain. No deduction for normal wear and tear.

Late fees and rent rules in Idaho
Idaho does not set a statutory cap on residential late fees and has no mandated grace period. A late fee is enforceable if it is written into the lease and reasonable; courts may void a punitive fee. (Note: the caps in § 55-2304 apply only to self-storage, not residential leases.)
Notice periods to end or not renew an Idaho lease
Idaho notice periods:
| Situation | Notice | Statute |
|---|---|---|
| Terminate month-to-month tenancy | One month (by either party) | § 55-208 |
| Nonpayment of rent | 3-day notice to pay or vacate | § 6-303 |
After a judgment, a residential tenant gets 72 hours to remove belongings. Self-help eviction is unlawful.
What disclosures must Idaho landlords provide?
Idaho requires very little at the state level:
- Lead-based paint (federal): the disclosure and EPA pamphlet for pre-1978 housing.
- No general state mandate: Idaho has no state-mandated residential-lease disclosure beyond federal lead paint; other disclosures (mold, etc.) are best practice, not statute.
What happens if an Idaho lease is missing required terms?
Specific failures carry specific consequences:
- Missed 21/30-day return / no itemization: forfeits the right to withhold and exposes the landlord to the deposit and possible damages (§ 6-321).
- Improper 3-day notice: an eviction can be dismissed if the notice does not comply with § 6-303.

How long does an Idaho landlord have to return a security deposit?
Within 21 days if the lease fixes no time, and never more than 30 days even if the lease specifies a longer period, with a written itemized statement (Idaho Code § 6-321).
Is there a late-fee limit in Idaho?
No. Idaho does not cap residential late fees; the fee must be in the lease and reasonable rather than punitive.

One month's written notice by either party (Idaho Code § 55-208). Nonpayment of rent requires a separate 3-day notice to pay or vacate (§ 6-303).
