Quick Reference: Idaho Security Deposit Rules

Most guidance on Idaho security deposits tells property managers that they must hold deposits in a separate account at a federally insured institution, segregated from operating funds. That comes from Section 6-321(4), added in 2021, and as far as it goes it is accurate.

What the guidance usually omits is the sentence that follows.

"The requirements of this subsection shall not apply to a property owner, managers who have common members or principals of the property owner entity, a real estate licensee, or a nonprofit business organization as established under chapter 30, title 30, Idaho Code."

A real estate licensee is exempt. Because Section 6-321(4) expressly excludes real estate licensees from its requirements, a manager who qualifies as a real estate licensee is outside this particular statutory separate-account requirement. That exemption does not eliminate any separate trust account, licensing, contractual or other applicable obligations.

A manager reading only the first half of subsection (4) is therefore working from an incomplete picture of which rule actually binds them.

This guide covers what Idaho actually requires, the two deadlines and which one applies when, the three things the itemized statement must contain, and the route a tenant takes to treble damages.

What Counts as a Deposit

Section 6-321(1) opens with a definition that is broader than most managers assume.

Amounts deposited by a tenant with a landlord for any purpose other than the payment of rent shall be deemed security deposits.

The label does not control. Section 6-321(1) treats amounts deposited with a landlord for a purpose other than payment of rent as security deposits. A payment labeled a "fee" may therefore fall within the statute depending on its purpose and how the deposit arrangement operates. Calling an amount "non-refundable" does not, by itself, remove it from the statute.

What can be kept. On termination of the lease and surrender of the premises, all amounts held as a security deposit shall be refunded to the tenant, except amounts necessary to cover the contingencies specified in the deposit arrangement.

Read that carefully, because it is unusual. Idaho does not give a closed statutory list of permitted deductions the way many states do. It ties retention to the contingencies specified in the deposit arrangement. What you can retain is, in the first instance, a function of what your own deposit agreement says it covers.

For a manager, that shifts work to the drafting stage. A deposit arrangement that describes the contingencies clearly is doing statutory work. A vague one leaves you arguing that a deduction falls within an unspecified purpose.

But one thing can never be retained. The landlord shall not retain any part of a security deposit to cover normal wear and tear.

Idaho Defines Normal Wear and Tear

Most states leave that phrase to the courts. Idaho puts a definition in the statute, and it is worth quoting in full because its scope is wider than the usual formulation.

"Normal wear and tear" means that deterioration which occurs based upon the use for which the rental unit is intended and without negligence, carelessness, accident, or misuse or abuse of the premises or contents by the tenant or members of his household, or their invitees or guests.

Three features matter.

• It is anchored to intended use. Deterioration is measured against the use for which the unit is intended, not against a pristine standard.

• It has four disqualifiers. Negligence, carelessness, accident, or misuse or abuse. Note that accident is on the list. Damage that nobody intended, and that nobody was careless about, still falls outside normal wear and tear if it was accidental.

• And it reaches beyond the tenant. The definition covers the tenant, members of his household, and their invitees or guests. Damage caused by a visitor is not normal wear and tear.

For a deduction to survive, the file needs to show which side of that definition the condition falls on. That is a documentation question answered at move-in, not at move-out.

Two Deadlines, and Which One Applies

Section 6-321(2) is one sentence and it is frequently misreported.

Refunds shall be made within twenty-one (21) days if no time is fixed by agreement and, in any event, within thirty (30) days after surrender of the premises by the tenant.

The structure is a default and a ceiling.

21 days is the default, and it applies where the rental agreement fixes no time for the refund. It is not a universal deadline.

30 days is the outer limit, and it applies in any event. A lease may fix a period, but it cannot push the refund past thirty days after surrender.

Two practical consequences follow.

Silence in the lease means 21 days. A manager whose agreement says nothing about the refund period is on the shorter clock, not the longer one. That is the opposite of what a manager assuming a general "30-day rule" would expect.

Both clocks run from surrender of the premises, not from the end of the term, not from the final inspection, and not from when the invoices arrive. Where surrender and lease expiry fall on different dates, the surrender date governs.

The Signed Statement Has Three Parts

Where the refund is less than the full amount deposited, the same subsection requires it to be accompanied by a signed statement containing three things:

1. The amounts lawfully retained by the landlord

2. The purpose for the amounts retained

3. A detailed list of expenditures made from the deposit

The third element is the one most often missing, and it is different from the first two.

Items 1 and 2 describe what you kept and why. Item 3 describes what you actually spent. A statement listing "carpet damage: $600" satisfies the first two and not the third. The subsection asks for a detailed list of expenditures made from the deposit, which means the underlying spend has to be documented and disclosed, not just the charge.

And the statement must be signed. Not merely sent, not merely written. Signed.

Because the statute requires a detailed list of expenditures made from the deposit, managers should support each deduction with the available invoices, receipts, work orders or other expenditure records rather than with an estimate prepared at the desk.

Where a repair has not yet been carried out by the time the statement is due, there is real tension between "amounts lawfully retained" and "expenditures made from the deposit." That is a point to take Idaho counsel's advice on rather than to resolve by assumption, particularly where the deadline is the 21-day default.

The Separate Account Rule and Its Four Exemptions

Section 6-321(4) was added by Chapter 197 of the 2021 Session Laws, and it is the newest part of the section.

The rule. A security deposit for a residential rental premises that is managed by a third-party manager of a landlord shall be maintained in a separate account at a federally insured financial institution, and that account shall be maintained separate from the third-party agent's operating account.

Two points on what the rule does not say. It does not require an interest-bearing account, despite some published guidance stating otherwise. And it does not require the institution to be located in Idaho, unlike the equivalent provisions in some other states.

The exemptions. The requirements of subsection (4) shall not apply to:

• a property owner

• managers who have common members or principals of the property owner entity

• a real estate licensee

• a nonprofit business organization as established under chapter 30, title 30, Idaho Code

The third exemption is the one most likely to matter to a professional manager. Where a manager qualifies as a real estate licensee, subsection (4) on its face does not apply to them.

That is not an invitation to commingle. Three things still bear on how a licensed manager holds deposits.

Your license obligations are separate. Trust account requirements attaching to a real estate license operate independently of Section 6-321, and being outside subsection (4) says nothing about them.

Your management agreement may require segregation. Many owner agreements do, and that obligation is contractual rather than statutory.

And the deposits are still the tenant's money. Section 6-321(1) requires them to be refunded, and Section 6-321(3) makes a new owner liable for refund on a sale. Neither depends on where the money sat.

The second exemption is worth reading closely too. It covers managers who have common members or principals of the property owner entity, which is an in-house or affiliated management structure rather than a genuinely third-party one.

When the Property Changes Hands

Section 6-321(3) is a single sentence with a significant consequence.

If security deposits have been made as to a particular rental or lease property, and the property changes ownership during a tenancy, the new owner shall be liable for refund of the deposits.

The liability transfers with the property. It does not depend on whether the deposits were actually handed over at closing, and it does not depend on what the sale contract says between buyer and seller.

For a manager involved in a transaction, that makes the deposit ledger a closing document. A buyer who takes the property without receiving the deposits has taken the liability without the funds, and the tenant's claim runs against the new owner regardless.

How a Tenant Gets to Treble Damages

The remedy does not sit in Section 6-321. It sits two sections earlier, and it has a precondition managers should know about.

Section 6-320(a) allows a tenant to file an action against a landlord for damages and specific performance on the grounds listed there, which include the landlord's failure in relation to a security deposit.

But standing requires notice first. Under Section 6-320(d), before a tenant has standing to file, the tenant must give the landlord three days' written notice, listing each failure or breach on which the action will be premised, together with a written demand requiring performance or cure.

That three-day letter is an opportunity, not a formality. It is the last point at which a missed deadline or a defective statement can be fixed without litigation, and a manager who processes those letters promptly can often resolve the matter for the deposit amount alone.

If it proceeds. Under Section 6-320(c), where the finding is for the tenant, judgment is entered for the amount of the damages assessed, and the court may also enter judgment requiring specific performance for any breach shown by the evidence, plus costs and disbursements.

And Section 6-317 provides the multiplier. Section 6-317 provides that where a landlord or tenant recovers damages for a forcible or unlawful entry or detention, or for an action brought pursuant to Section 6-320, judgment may be entered for three (3) times the amount at which the actual damages are assessed.

Attorney fees are a separate question, and the answer is counterintuitive. Section 6-324 generally entitles the prevailing party to attorney fees in actions under the chapter, except in cases where treble damages are awarded. A tenant who wins treble damages therefore does not pick up statutory fees under that section as well. Other sources of fees may apply depending on the case.

Note also that Section 6-320(c) provides separately for costs and disbursements, which is not the same thing as attorney fees.

Note that the three-day notice requirement in Section 6-320(d) applies across all the grounds in that section, not only to deposit claims. Idaho case law has confirmed that a Section 6-321 deposit claim triggers it.

What Idaho Does Not Require

Four absences define Idaho deposit practice, and together they place unusual weight on the lease.

• No cap. Section 6-321 sets no limit on the amount that may be collected.

• No interest. The section contains no interest requirement, for any holding period.

• No escrow requirement for owners or licensees. Subsection (4) reaches third-party managers, subject to its four exemptions.

• No statutory list of permitted deductions. Retention is measured against the contingencies specified in the deposit arrangement, subject to the bar on normal wear and tear.

The through-line is that Idaho leaves a great deal to the agreement. Where the lease and deposit arrangement are silent or loose, the statute does not fill the gap in the landlord's favor.

Common Idaho Deposit Mistakes

1. Assuming 30 days is the deadline
Twenty-one days applies where the agreement fixes no time. Thirty days is the ceiling, not the default.

2. Running the clock from lease expiry or from the inspection
Both periods run from surrender of the premises by the tenant.

3. Sending a statement that lists charges but not expenditures
Section 6-321(2) requires a detailed list of expenditures made from the deposit, in addition to the amounts retained and their purpose.

4. Not signing the statement
The subsection requires a signed statement.

5. Treating a fee as outside the section because it is labeled non-refundable
Section 6-321(1) captures amounts deposited for any purpose other than payment of rent.

6. Deducting for accidental damage as if it were wear and tear, or vice versa
The statutory definition excludes negligence, carelessness, accident, and misuse or abuse.

7. Ignoring damage caused by a guest
The definition reaches the tenant, household members, and their invitees or guests.

8. Relying on a vague deposit arrangement
Retention is tied to the contingencies specified in that arrangement.

9. Assuming subsection (4) binds you because you are a manager
Real estate licensees, owners, affiliated managers and qualifying nonprofits are exempt from it.

10. Assuming an exemption from subsection (4) means no account obligations
License trust account requirements and the management agreement operate independently.

11. Buying a property without taking the deposits
Under Section 6-321(3) the new owner is liable for refund regardless.

12. Treating a tenant's three-day letter as routine correspondence
Under Section 6-320(d) it is the precondition to an action that can carry treble damages.

The Records That Decide an Idaho Deposit Case

Idaho's deposit disputes turn on three questions, and the statute answers none of them for you.

• Was the condition normal wear and tear?
  The statutory definition in Section 6-321(1) is the test, and it turns on whether deterioration arose from intended use without negligence, carelessness, accident, misuse or abuse by the tenant, their household, or their invitees or guests. That is a comparison between the unit at move-in and the unit at move-out, which means a documented move-in and move-out condition record is often the most important evidence connecting a claimed deduction to the statutory test.

• What did you actually spend?
  Because the signed statement must include a detailed list of expenditures made from the deposit, the itemization has to reconcile to real work orders and invoices. The guidance on how to manage maintenance requests covers building that trail during the tenancy rather than assembling it in three weeks.

• When did the tenant surrender?
  Both deadlines run from that date, and it is often less obvious than it looks. Keys returned on one day, possessions removed on another, and a formal lease end on a third produce three candidate dates.

RIOO keeps the lease and the deposit arrangement that defines the retainable contingencies in Contracts & Renewals, the deposit ledger in Collecting Rent & Payments, the move-in and move-out condition record in Move Ins & Move Outs, and the repair spend behind each line of the itemized statement in Service Request & Task Management.

Conclusion

Idaho's deposit statute is short, and most of its weight falls on documents a manager controls rather than on rules the statute supplies.

There is no cap, no interest requirement, and no closed list of permitted deductions. What you may retain is measured against the contingencies specified in the deposit arrangement, which makes that arrangement the operative document. The one absolute bar is normal wear and tear, and Idaho defines that term itself, in language that excludes accident and reaches guests.

The deadlines reward reading the sentence carefully. Twenty-one days if the agreement fixes no time. Thirty days in any event. Both run from surrender.

The signed statement has to do three jobs, and the third is the one that catches people: a detailed list of expenditures made from the deposit, not merely the amounts retained and their purpose.

And the separate account rule in subsection (4) is narrower than it appears, because real estate licensees, owners, affiliated managers and qualifying nonprofits are exempt. That is an exemption from one statutory subsection, not from the license obligations or contractual duties that sit alongside it.

For managers in Boise, Meridian, Nampa, Idaho Falls and Coeur d'Alene, the sequence is short. Check whether the lease fixes a refund period, and diary 21 days if it does not. Fix the surrender date in the file on the day it happens. Build the itemized statement from actual expenditures and sign it. Draft deposit arrangements that name the contingencies rather than gesturing at them. And treat any three-day letter under Section 6-320(d) as the last inexpensive off-ramp before a treble damages claim.

Frequently Asked Questions

Q1. How much can an Idaho landlord charge as a security deposit?
Section 6-321 sets no cap. The amount is a matter for the rental agreement.

Q2. How long does an Idaho landlord have to return a deposit?
Under Section 6-321(2), within 21 days if no time is fixed by agreement, and in any event within 30 days after surrender of the premises by the tenant.

Q3. Does a lease have to specify the return period?
No, but if it does not, the 21-day default applies. Where the agreement fixes a period, that period governs, subject to the 30-day outer limit.

Q4. What must the itemized statement contain?
Under Section 6-321(2), a signed statement itemizing the amounts lawfully retained, the purpose for the amounts retained, and a detailed list of expenditures made from the deposit.

Q5. What counts as a security deposit in Idaho?
Under Section 6-321(1), amounts deposited by a tenant with a landlord for any purpose other than the payment of rent.

Q6. Can an Idaho landlord deduct for normal wear and tear?
No. Section 6-321(1) prohibits it and defines normal wear and tear as deterioration occurring from the use for which the unit is intended and without negligence, carelessness, accident, or misuse or abuse by the tenant, members of the household, or their invitees or guests.

Q7. Does Idaho require deposits to be held in a separate account?
Under Section 6-321(4), a deposit for premises managed by a third-party manager must be kept in a separate account at a federally insured financial institution, separate from the agent's operating account. The subsection expressly does not apply to a property owner, managers with common members or principals of the owner entity, a real estate licensee, or a qualifying nonprofit.

Q8. Does Idaho require interest on security deposits?
Section 6-321 contains no interest requirement.

Q9. What happens to deposits when an Idaho property is sold?
Under Section 6-321(3), where the property changes ownership during a tenancy, the new owner is liable for refund of the deposits.

Q10. What can an Idaho tenant do if the deposit is not returned?
Under Section 6-320(a), a tenant may bring an action for damages and specific performance, but under Section 6-320(d) must first give the landlord three days' written notice listing each failure and demanding performance or cure. If the action proceeds and damages are recovered, Section 6-317 provides that judgment may be entered for three times the amount at which the actual damages are assessed.

Q11. Does a winning tenant also get attorney fees?
Not automatically alongside treble damages. Section 6-324 entitles the prevailing party to attorney fees in actions under the chapter except in cases where treble damages are awarded. Section 6-320(c) separately provides for costs and disbursements.
