Idaho Landlord-Tenant Laws (2026): Deposits, Habitability, and Tenant Rights

Idaho Landlord-Tenant Laws (2026): Deposits, Habitability, and Tenant Rights
Idaho has no statutory cap on security deposits and requires landlords to return them within 21 days (or up to 30 days by written agreement). Idaho has no statute requiring advance notice before a landlord enters and does not allow tenants to use repair-and-deduct.
Security deposits in Idaho
Idaho law does not cap how much a landlord may charge for a security deposit. A landlord may set the deposit at one month's rent, two months, or more, depending on the rental market and the tenant's creditworthiness. Because there is no cap, tenants should negotiate deposit amounts before signing and document the unit's condition thoroughly at move-in.
Idaho Code 6-321 requires landlords to return the security deposit, along with a written itemized statement of deductions, within 21 days after the tenancy ends. If the written lease allows it, that period can be extended to a maximum of 30 days. A landlord who fails to provide a proper accounting within the applicable deadline forfeits the right to make any deductions and must return the full deposit.
| Rule | Idaho standard |
|---|---|
| Maximum deposit | No statutory cap |
| Return deadline | 21 days (up to 30 by agreement) |
| Interest required | No |
| Itemized statement required | Yes, within the return deadline |
When can a landlord enter? Notice rules
Idaho has no statute that specifies how much advance notice a landlord must give before entering a residential rental unit. Courts and housing practitioners treat 24 hours as a reasonable standard, but it is not enforceable as a hard legal deadline under Idaho Code.

Because there is no mandatory notice period, tenants in Idaho are encouraged to include a notice provision in the written lease (for example, 24-hour advance written notice). Entry must still occur at reasonable times under general common-law principles. A landlord may enter immediately in a genuine emergency, such as a fire, flood, or serious structural hazard, without any advance notice. Tenants who experience repeated, harassing, or unreasonable entries should document each incident and seek legal advice.
Ending a lease: notice to vacate
Both landlords and tenants must give 30 days' written notice to end a month-to-month tenancy in Idaho. Unlike some states, Idaho applies the same 30-day period to both parties. Notice should be delivered in writing and timed so that it expires on or before the last day of a rental period.
For fixed-term leases, no additional notice is required; the lease ends on the agreed date. If a landlord needs to terminate a tenancy for nonpayment of rent, failure to cure a lease violation, or other cause, different procedures apply. See the Idaho eviction notice page for the specific notice forms and timelines that apply to each situation.
Repairs and the warranty of habitability
Idaho recognizes an implied warranty of habitability. Landlords must maintain rental units in a condition that is safe, weathertight, and functional, including working plumbing, adequate heating, structurally sound walls and roof, and freedom from infestation. Failure to meet that standard can expose landlords to liability.
However, Idaho does not give tenants a general repair-and-deduct remedy. Tenants cannot unilaterally arrange repairs and subtract the cost from rent (except for a narrow exception: tenants may purchase and install smoke detectors themselves if the landlord fails to do so). If a landlord refuses to make necessary repairs, Idaho tenants must pursue remedies through the courts, either by filing a lawsuit to compel repairs and recover damages, or by seeking to terminate the lease for a material breach of the habitability warranty. Contacting local code enforcement is another practical first step when conditions are dangerous.
Rent, late fees, and rent control
Idaho sets no statutory cap on late fees. A landlord may charge any amount, provided the fee is clearly stated in the written lease and is not so excessive as to be an unenforceable penalty under general contract principles. Tenants should review the lease carefully before signing to understand what late fees apply and when they kick in.

Idaho law preempts local rent control statewide. No city or county in Idaho may enact an ordinance limiting how much a landlord may charge or how much rent may increase. Landlords may raise rent on a month-to-month tenancy by giving at least 30 days' notice before the next rent due date. There is no limit on the amount of the increase.
If you have a landlord-tenant dispute in Idaho
Document everything from the beginning. Move-in and move-out inspection reports with photographs are the most valuable evidence in deposit disputes. Send all repair requests, complaints, and notices in writing, and keep copies.
If your landlord withholds your deposit without proper itemization or misses the 21-day (or 30-day) return deadline, you may file in Idaho Small Claims Court. Idaho's small claims limit is $5,000. You do not need an attorney for small claims, and the court filing fee is modest. Bring your lease, move-in photos, and any written correspondence.
For habitability problems that the landlord will not fix, contact your local county or city code enforcement office. They can inspect the unit and issue a formal notice to the landlord. For more complex disputes or if you need help understanding your rights, Idaho Legal Aid Services provides free or low-cost assistance for qualifying tenants. Consulting a licensed Idaho attorney before withholding rent or terminating a lease is strongly recommended, given the lack of a repair-and-deduct remedy.
This article is general legal information, not legal advice. Landlord-tenant rules vary by state and city and change, and some cities add their own ordinances. For advice about a specific situation, consult a licensed attorney or your state housing agency.
