Renting a home or apartment in Iowa? If you’re a tenant, it’s important to understand your rights—especially when it comes to rent increases. In 2025, Iowa’s rental laws remain relatively landlord-friendly, but there are still rules landlords must follow.
Whether you’re worried about a sudden hike in rent or just want to be prepared, this guide breaks down everything Iowa tenants should know about rent increase laws in 2025.
Are There Any Rent Control Laws in Iowa?
No, Iowa does not have statewide rent control laws.
This means that landlords can increase rent by any amount, as long as they follow proper notice procedures. Unlike in some other states, there’s no legal limit on how much rent can be raised.
So, technically, your landlord could raise your rent by $50, $150, or even more—but they must give you notice first.
How Much Notice Is Required for a Rent Increase in Iowa?
In Iowa, the amount of notice your landlord must give depends on your lease type:
Month-to-Month Lease:
Landlords must give at least 30 days’ written notice before increasing rent.
Fixed-Term Lease (e.g., 12 months):
The landlord cannot increase rent during the lease term, unless the lease specifically allows it. Rent can only be raised when renewing the lease.
That means if you signed a one-year lease, your rent stays the same for that year—unless your contract says otherwise.
How Must Notice Be Given?
The rent increase notice must be:
In writing (verbal notices do not count)
Delivered personally, by mail, or sometimes by posting on the door (if allowed in the lease)
Given at least 30 days before the increase takes effect for month-to-month tenants
If proper notice isn’t given, the rent increase is not legally enforceable.
Can a Landlord Raise Rent for Discriminatory or Retaliatory Reasons?
No. Even though Iowa does not limit how much rent can be increased, landlords cannot raise rent to punish or discriminate against tenants.
For example, your landlord cannot increase rent:
Because you filed a complaint about repairs
In retaliation for joining a tenant rights group
Based on race, religion, gender, disability, or other protected categories under the Fair Housing Act
If you believe a rent increase is being used as retaliation or discrimination, you can file a complaint with the Iowa Civil Rights Commission or seek legal help.
Does Iowa Require Justification for Rent Increases?
No. Landlords in Iowa do not have to give a reason for raising your rent. As long as they follow the notice rules and don’t violate anti-discrimination or anti-retaliation laws, they’re allowed to increase rent at their discretion.
However, you can always negotiate—especially if you’re a good tenant with a clean record and timely payments.
How Often Can a Landlord Increase Rent in Iowa?
There is no law limiting how often a landlord can raise rent. However:
For month-to-month leases, they can raise rent once every 30 days (with notice).
For fixed-term leases, they can raise rent only at renewal time unless otherwise stated in the lease.
If you’re facing frequent increases, consider switching to a longer lease for more stability.
Tips for Tenants Facing Rent Increases
Here are a few steps you can take if your rent goes up:
Review your lease: Make sure the increase follows the rules.
Check for proper notice: If you didn’t get written notice at least 30 days in advance, the increase may not be valid.
Negotiate: Ask your landlord if they’re open to a smaller increase or a longer lease term in exchange for stable rent.
Get everything in writing: Any new rent amount or lease terms should be signed by both parties.
Iowa law gives landlords the freedom to increase rent without limits, but they must provide proper notice and follow fair housing rules.
As a tenant, your best defense is knowledge—know your lease, know your rights, and don’t be afraid to speak up if something feels unfair. With the right information, you can make smart choices and stay protected, even in a changing rental market.
