Iowa: Security Deposit Return Deadlines & Deductions

Requirements one by one

Governing law

Iowa's entire rental-deposit scheme lives in one section of its Uniform
Residential Landlord and Tenant Law: Iowa Code § 562A.12.

Deadline to return the deposit

The 30-day clock has two triggers, and both have to be satisfied before it
starts: "A landlord shall, within thirty days from the date of termination of
the tenancy and receipt of the tenant's mailing address or delivery
instructions, return the rental deposit to the tenant or furnish to the
tenant a written statement showing the specific reason for withholding of the
rental deposit or any portion thereof." (§ 562A.12(3)(a)). In practice, that
means a tenant who delays giving a forwarding address also delays the
landlord's deadline. If the tenant never gives an address at all, the
consequence flips sharply: "If no mailing address or instructions are
provided to the landlord within one year from the termination of the tenancy
the rental deposit shall revert to the landlord and the tenant will be deemed
to have forfeited all rights to the rental deposit." (§ 562A.12(4)).

Itemized statement required?

Yes, if any amount is withheld. The written statement has to give "the
specific reason for withholding," and if the withholding is for damage to the
unit, "the statement shall specify the nature of the damages" (§
562A.12(3)(a)). If it ever comes to a dispute, the landlord — not the tenant
— carries the burden: "the burden of proving, by a preponderance of the
evidence, the reason for withholding all or any portion of the rental deposit
shall be on the landlord." (§ 562A.12(3)(b)).

What can be deducted

The statute lists three permitted uses: unpaid rent or other money owed under
the lease, restoring the unit to its move-in condition (ordinary wear and
tear excepted), and — a distinctive third category — the landlord's expenses
in retaking possession from a tenant who held over in bad faith after being
told they were noncompliant with the lease (§ 562A.12(3)(a)).

Maximum deposit amount

Iowa caps the deposit at two months' rent: "A landlord shall not demand or
receive as a security deposit an amount or value in excess of two months'
rent." (§ 562A.12(1)).

Interest on the deposit?

Iowa doesn't require the deposit to earn interest at all. If a landlord does
choose to hold it in an interest-bearing trust account, the statute
expressly gives the landlord the first five years' worth of interest: "Any
interest earned on a rental deposit during the first five years of a tenancy
shall be the property of the landlord." (§ 562A.12(2)). The statute doesn't
say what happens to interest earned after that five-year mark — it's simply
silent on that point, so don't assume a tenant automatically collects it
without checking further guidance.

Penalty for a late/bad-faith withholding

Two different, independent consequences can apply. First, missing the
30-day written-statement deadline is an automatic forfeiture — the landlord
"shall forfeit all rights to withhold any portion of the rental deposit" (§
562A.12(4)), with no fault or bad-faith showing required. Second, and
separately, "the bad-faith retention of a deposit by a landlord... shall
subject the landlord to punitive damages not to exceed twice the monthly
rental payment in addition to actual damages" (§ 562A.12(7)) — notably
pegged to the monthly rent, not the deposit amount, which can make the
penalty bigger or smaller than the deposit itself depending on the numbers.
On top of either, "the court may, in any action on a rental agreement, award
reasonable attorney fees to the prevailing party" (§ 562A.12(8)) — a
fee-shifting rule that isn't limited to tenants; a landlord who successfully
defends a claim can recover fees too.

Separate account or bond required?

Yes. Deposits must sit in a federally insured bank, savings and loan
association, or credit union account, and can't be mixed with the landlord's
own funds: "Rental deposits shall not be commingled with the personal funds
of the landlord." (§ 562A.12(2)). The account may be a common trust account
shared across tenants, and it may (but doesn't have to) be interest-bearing.

What trips people up

Sending your forwarding address late pushes the landlord's deadline back
too. Because the 30-day clock only starts once the landlord has both ended
the tenancy AND received your mailing address, a tenant who waits weeks to
send a forwarding address is also giving the landlord that much extra time.

Waiting more than a year to give an address can cost you the whole
deposit. If the landlord never receives your mailing address or delivery
instructions within one year of the tenancy ending, the deposit reverts to
the landlord outright under § 562A.12(4) — send your address promptly, even
if you're still working out where any dispute stands.

A sold rental property doesn't erase your deposit claim, but you have only
20 days to dispute the transferred amount. When a landlord's interest in
the property ends, the successor landlord takes on the deposit obligations,
but if the tenant doesn't object to the amount stated in the transfer notice
within 20 days, the successor's liability is capped at that stated amount (§
562A.12(6)).

Common questions

My landlord never sent anything after I moved out and gave my new
address — what happens? If more than 30 days have passed since both
events, the landlord has forfeited the right to withhold any of the deposit
under § 562A.12(4), regardless of whether there was real damage.

Is the bad-faith penalty based on my deposit or my rent? Your monthly
rent. Iowa's punitive-damages cap is "twice the monthly rental payment," not
twice the deposit, so calculate it off your rent amount.

Do I get interest on my deposit? Only if the landlord chose to put it in
an interest-bearing account, and even then only interest earned after the
tenancy's first five years — the statute gives the landlord all interest
earned during those first five years.
