Key Lease Addendums Iowa Renters Should Know

Lease Agreements & Renewals Iowa published: June 21, 2025 Flag of Iowa

Before signing or renewing a lease in Iowa, it's important for renters to understand how lease addendums can affect their housing rights and responsibilities. A lease addendum is a legal document that adds to or changes parts of your original rental agreement. In Iowa, there are specific addendums landlords may use—some required by law, others optional. Knowing what to watch for can help protect your interests and prevent misunderstandings with your landlord.

What Is a Lease Addendum?

A lease addendum is an additional document attached to your rental lease. Unlike amendments, which change sections of the existing lease, an addendum introduces new rules or clarifies details that weren't covered in the original rental contract. Addendums are legally binding if signed by both landlord and tenant.

Common Lease Addendums in Iowa

Landlords in Iowa may include different types of addendums. While some are legally required, others are at the landlord’s discretion. Always review each addendum carefully before signing.

  • Lead-Based Paint Disclosure Addendum (Required for Pre-1978 Housing): Federal law requires landlords to provide this if the property was built before 1978. It informs tenants about potential health risks from lead paint and must be signed before moving in. More on lead disclosure requirements.
  • Pest Control Addendum: Outlines responsibilities for pest prevention and treatment. This can specify if tenants must report infestations or if certain pests (bedbugs, cockroaches) are the landlord’s responsibility.
  • Pet Addendum: Details rules for keeping pets, including deposits, breed restrictions, or additional cleaning requirements.
  • Maintenance/Repairs Addendum: May clarify procedures on how to request repairs, tenant obligations for minor issues, and response times.
  • Smoke-Free Property Addendum: States if smoking is allowed or bans smoking in specific areas.
  • Guest Policy Addendum: Limits on overnight guests or defines what constitutes a "guest" versus a permanent occupant.

Official Forms Iowa Renters Should Know

  • Lead-Based Paint Disclosure Form (No numbered state form)
    When used: For rental units built before 1978. Must be signed and retained for at least three years.
    Practical example: Before moving in, your landlord hands you this addendum. Read it, ask questions if unsure, then sign only if you understand all disclosures.

Other addendums (like pet or guest policies) are usually drafted by the landlord and not standardized by the state.

Can a Landlord Add or Change Addendums Mid-Lease?

Generally, lease addendums can only be added or altered during lease renewal unless you and your landlord both agree to the change. If you’re asked to sign a new addendum after a lease has started, review it carefully. You are not required to accept changes that affect your rights or obligations without your consent.

What to Watch for in Lease Addendums

It's wise to read every addendum with caution, as some can impact your privacy, freedom, or finances. Here are tips for Iowa renters:

  • Deposit and Fee Changes: Check for any addendum that increases the security deposit or introduces new fees beyond what’s in the original lease.
  • Rules on Entry: Look for clauses stating when and how your landlord can enter your home. Iowa law usually requires notice (Iowa Code § 562A.19), except in emergencies.
  • Early Termination Addendums: These outline required notice periods and potential penalties if you want to end the lease early. Iowa generally does not require landlords to allow early termination except under certain conditions.
If an addendum seems unfair or you don’t understand it, consider asking a trusted resource or Iowa legal aid program for advice before signing.

How to Respond if You Disagree With an Addendum

If you’re uncomfortable with an addendum:

  • Talk to your landlord and share your concerns.
  • Don’t sign unless you agree with all terms.
  • Contact a local housing agency or legal services office if needed.

If needed, you can file a complaint with the Iowa Civil Rights Commission if you believe an addendum discriminates against you or limits your legal rights.

Relevant Laws and Where to Get Help

The Iowa Uniform Residential Landlord and Tenant Law (Iowa Code Chapter 562A) is the key state law covering lease agreements and addendums. For complaints or disputes, Iowa does not have a specialized rental tribunal; instead, housing cases are addressed through Iowa's district court system.
