Iowa Rent Increase Rules at a Glance
| Statewide rent cap | NO — Iowa has no statewide rent cap. There is no percentage limit or formula restricting how much a landlord can raise rent. Landlords may raise rent by any amount, provided the increase is not retaliatory (Iowa Code 562A.36) or discriminatory (Iowa Code Chapter 216). |
| Notice required before increase | 30 days written notice for all residential tenancies under Iowa Code 562A.13(5), including both month-to-month and week-to-week tenancies. The effective date of the increase cannot be sooner than the expiration date of the current rental agreement or any renewal or extension. For mobile home parks under Iowa Code Chapter 562B, landlords must give 60 days written notice for rent increases and 90 days written notice for lot fee increases. |
| How often rent can be raised | No statutory limit on frequency. A landlord may raise rent as often as they choose, as long as proper 30-day written notice is given each time and the increase does not take effect before the current lease term or renewal period expires. For mobile home parks under Chapter 562B, lot rent may only be raised once every 12 months. |
| During a fixed-term lease | Generally NO. Under Iowa Code 562A.13(5), the effective date of a rent increase cannot be sooner than the expiration date of the original rental agreement or any renewal or extension. The one exception is if the lease contains a rent escalation clause or other provision specifically allowing mid-lease increases — under 562A.9, parties may agree to such terms as long as they are not otherwise prohibited by law. |
Retaliatory increases: YES — Iowa Code 562A.36 prohibits retaliatory rent increases. A landlord may not raise rent in retaliation after a tenant: (a) complains to a government agency about building or housing code violations materially affecting health and safety; (b) complains to the landlord about a violation of the landlord’s duty to maintain fit premises under 562A.15; or (c) organizes or joins a tenants’ union or similar organization.
If a tenant filed a good-faith complaint within one year before the alleged retaliatory act, a presumption of retaliation is created, shifting the burden to the landlord. However, the landlord may defeat this presumption by showing the rent increase is commensurate with legitimate increased costs of owning, maintaining, or operating the property.
Iowa Cities With Local Rent Control
None. No city in Iowa has a local rent control ordinance. Iowa Code 364.3(9) expressly prohibits cities from adopting or enforcing any ordinance limiting the amount of rent that can be charged for private residential or commercial property.
Exempt properties: Iowa Code 562A.5 excludes the following from Chapter 562A protections: (1) institutional residences where occupancy is incidental to detention or the provision of medical, geriatric, educational, counseling, religious, or similar services; (2) occupancy by a purchaser under a contract of sale; (3) occupancy by a member of a fraternal or social organization in a structure operated for the organization’s benefit; (4) transient occupancy in hotels, motels, or similar lodgings; (5) occupancy by an employee of a landlord whose right to occupy is conditional upon employment on the premises.
Mobile home parks are governed separately under Chapter 562B, not 562A.
State preemption: YES — Iowa Code 364.3(9) expressly preempts local rent control. Cities are prohibited from adopting or enforcing any ordinance imposing any limitation on the amount of rent charged for leasing private residential or commercial property. The only exception is city-owned property — cities may set rental rates on properties in which the city has a property interest.
What to Do If Your Rent Increase Is Illegal
If you believe your rent increase is retaliatory, you may file a lawsuit under Iowa Code 562A.36 to recover actual damages and reasonable attorney fees, and you have a defense against any eviction action. If the increase is discriminatory, you may file a complaint with the Iowa Civil Rights Commission under the Iowa Civil Rights Act (Chapter 216) or file a federal Fair Housing complaint with HUD.
If you received fewer than 30 days written notice, the increase is not yet effective and you may continue paying the prior rent amount.

If your landlord attempts a mid-lease increase without an escalation clause, you may refuse to pay the increase since the existing lease governs. You may also file a consumer complaint with the Iowa Attorney General’s Consumer Protection Division or contact Iowa Legal Aid at iowalegalaid.org for free legal assistance. Many tenants find it helpful to document all communications and keep copies of their lease and any notices received.
Other Iowa rent rules: Iowa caps late fees based on monthly rent: for rent of 700 or less, the maximum is 12 per day and 60 per month; for rent over 700, the maximum is 20 per day and 100 per month (Iowa Code 562A.9).
If a rental agreement does not fix a definite term, the tenancy defaults to week-to-week for a roomer paying weekly rent and month-to-month in all other cases (Iowa Code 562A.9).
Iowa’s one-year retaliation presumption under 562A.36(2) is notably tenant-friendly — a complaint made within one year before an alleged retaliatory act creates a rebuttable presumption of retaliation. Iowa also has a unique commensurate-cost defense allowing landlords to justify a rent increase by proving it matches legitimate increased costs of ownership, maintenance, or operation.

Understanding Iowa Rent Increase Laws
Whether a Iowa rent increase is legal depends on the cap (if any), the notice given, and whether the increase is retaliatory. Iowa rent increase laws protect tenants from surprise hikes by requiring a minimum notice period before any increase takes effect.
If you believe a Iowa rent increase violates these rules, document the notice you received, check the math against the cap, and contact your local housing authority or legal-aid office.
Knowing the Iowa rent increase rules before your lease renews puts you in a much stronger position.
