Move-out season brings the same question to landlords and renters across Southeastern Idaho: how much of the security deposit comes back, and when? Whether you own a duplex in Pocatello, a single-family rental in Idaho Falls, or student housing near Rexburg, the answer comes from one short section of state law, Idaho Code Section 6-321. Here’s what it says in plain English.

What counts as a security deposit in Idaho?

Under Idaho Code 6-321(1), any money a tenant gives a landlord for any purpose other than paying rent is treated as a security deposit. That means a “cleaning fee,” “pet deposit,” or “damage deposit” collected up front generally falls under the same rules. If it isn’t rent, plan on treating it like a deposit.

How fast does a landlord have to return the deposit?

Idaho sets two deadlines, both counted from the day the tenant surrenders the premises (Idaho Code 6-321(2)):

  • 21 days if the lease doesn’t set a different timeframe.
  • 30 days at the most, even if the lease says otherwise.

So a lease can stretch the refund window from 21 to 30 days, but no further. Landlords who manage several units should put the move-out date on the calendar the day keys come back.

What can be deducted, and what can’t?

A landlord may keep only the amounts needed to cover the contingencies listed in the deposit arrangement, typically unpaid rent, damage, or cleaning beyond normal use. The statute is clear that a landlord can’t keep any part of the deposit to cover normal wear and tear.

Idaho law defines normal wear and tear as deterioration that happens from the intended use of the unit, without negligence, carelessness, accident, misuse, or abuse by the tenant, their household, or their guests (Idaho Code 6-321(1)). In practice, that usually separates things like:

  • Likely normal wear and tear: lightly faded paint, minor scuffs, carpet worn along walking paths after years of use.
  • Likely damage: holes in walls, pet stains, broken blinds or fixtures, burns in countertops.

The age of the item matters too. Ten-year-old carpet that’s simply worn out is a lot harder to charge for than carpet that was new when the tenant moved in.

The itemized statement requirement

If the tenant gets back anything less than the full deposit, the refund must come with a signed, itemized statement showing what was kept, why, and a detailed list of expenditures made from the deposit (Idaho Code 6-321(2)). A single line that says “cleaning and repairs: $600” doesn’t meet that standard. Receipts, invoices, and dated move-in and move-out photos make the statement easy to defend.

What happens if the rental is sold mid-lease?

This one surprises a lot of investors. If a property changes hands during a tenancy, the new owner is responsible for refunding the deposits (Idaho Code 6-321(3)). If you’re buying a rental in Southeastern Idaho, make sure the deposits are credited to you at closing and that you get a deposit ledger for every tenant.

Rules for third-party property managers

When a residential rental is run by a third-party manager, deposits must be held in a separate account at a federally insured financial institution, apart from the manager’s operating account. The statute exempts property owners, managers who share members or principals with the ownership entity, real estate licensees, and certain nonprofits (Idaho Code 6-321(4)). Even when the exemption applies, keeping deposits separate is simply good practice.

Does Idaho cap the size of a security deposit?

Section 6-321 doesn’t set a maximum deposit amount. Local market conditions in Pocatello, Idaho Falls, and Rexburg tend to set the practical ceiling, since a deposit that’s far above what nearby rentals ask can slow down leasing.

A simple move-out checklist for Idaho landlords

  1. Write the surrender date down and count 21 days (or the lease term, up to 30).
  2. Walk the unit and photograph every room, ideally comparing against move-in photos.
  3. Separate normal wear and tear from actual damage.
  4. Gather receipts or invoices for every deduction.
  5. Send the refund with a signed, itemized statement if anything is withheld.
