Iowa Security Deposit Law: The 30-Day Rule and the Two-Month Cap
Last reviewed: July 2026
Iowa’s deposit rules have two numbers every landlord should know cold: a cap on how much you can collect, and a deadline for giving it back. Here is the plain-English version for independent landlords.
The two-month cap
An Iowa landlord may not demand or receive a security deposit greater than two months’ rent. Whatever you collect at move-in has to stay within that limit.
The 30-day deadline — and when it starts
After the tenancy ends, an Iowa landlord has 30 days to return the deposit, minus any lawful deductions, along with a written itemized statement of what was withheld.
The 30-day clock has a specific trigger: it starts once the tenant gives you a forwarding address. Ask for that address at move-out and note the date you receive it — that’s the date your deadline runs from.
What you can withhold
An Iowa landlord may withhold to cover unpaid rent and other amounts the tenant owes under the lease, and to restore the unit from damage beyond ordinary wear and tear.
Give the tenant an itemized written statement for anything you keep. Keep each line specific and tied to actual damage or an unpaid amount.
What you cannot deduct
You can’t charge the tenant for ordinary wear and tear — the normal aging of a unit from someone living in it. The deduction has to be for damage or unpaid obligations, not routine turnover.
A documented move-in condition report with dated photos is your evidence that a charge reflects real damage rather than expected wear.
Why missing the deadline is expensive
If an Iowa landlord fails to return the deposit or provide the itemized statement within 30 days of getting the forwarding address, the landlord can lose the right to keep any of it. Bad-faith retention can expose the landlord to further damages on top of returning the money. Document move-in, itemize every deduction, and send it within 30 days — every time.
How Landlord Command helps
- Security deposit tracking — Track each deposit, its status, and an itemized return — so your state’s return deadline is never a scramble.
- Move-in / move-out inspections — Document unit condition with photos at check-in and compare at move-out — your record if a deduction is ever questioned.
Frequently asked questions

What can an Iowa landlord deduct from a deposit?
Unpaid rent and other amounts owed under the lease, plus the cost of repairing damage beyond ordinary wear and tear — each described in a written itemized statement.
