Illinois Mobile Home Park Rent Increase Limits Explained

Understanding rent increase limits in Illinois mobile home parks is essential for protecting your rights as a resident. Illinois state law sets specific rules on how much and how often your rent may be raised, as well as the kind of notice your landlord must provide. This guide explains these laws in plain language, helping you understand when a rent hike is legal and what steps you can take if you feel your rights have been violated.

How Rent Increases Work in Illinois Mobile Home Parks

In Illinois, the regulation of mobile home park rent increases is outlined in the Illinois Mobile Home Landlord and Tenant Rights Act. While Illinois does not have statewide rent control—meaning landlords generally have discretion to set rent amounts—there are laws about how and when rent increases may take place in mobile home parks.

Rules for Rent Increases

  • Notice Requirement: Landlords must provide at least 90 days' written notice before increasing rent (Section 6 of the Act).
  • Frequency: Rent can generally only be increased once per 12-month lease term or renewal term.
  • No Cap: Illinois law does not set a percentage or dollar limit to how much rent can be increased, but increases cannot be retaliatory or discriminatory.
  • Prohibited Actions: Landlords may not increase rent to retaliate against residents for exercising their legal rights or for filing complaints.

Always review your written lease, as some mobile home park leases could specify different timelines or caps, so long as they do not conflict with state law.

What Your Rent Increase Notice Must Include

By law, your landlord's notice of rent increase must:

  • Be in writing, delivered to you personally or sent by first class mail.
  • State the new rent amount and the effective date (no less than 90 days from the notice date).

If you receive a rent increase notice, check the date and details to confirm it meets these requirements. If not, you may have grounds to dispute it.

Official Form: Example and How to Use

Illinois does not provide a mandatory statewide rent increase notice form. However, landlords must still give you the required written notice. If you want to respond or dispute an improper notice, practical tools include:

  • Complaint to the Illinois Department of Public Health: Use if you believe the increase is retaliatory or in bad faith.
    Official form: Manufactured Home Community Complaint Form (PDF). Submit to the Department as directed. For example, if your landlord raises rent after you report a safety issue, you can file this form to launch an investigation.

What To Do If You Think Your Rent Increase Is Unfair or Improper

  • Document everything: Keep copies of your lease, rent increase notice, and all correspondence.
  • Contact your landlord in writing if you believe the increase violates the law or your lease.
  • If the rent increase is retaliatory or discriminatory, you can file a formal complaint with the Illinois Department of Public Health (see above for the form).
If you need help understanding your rights or if you face eviction after a rent dispute, contact the Illinois Dispute Resolution services or a local legal aid organization.

Official Tribunal Handling Tenancy Issues

In Illinois, the main agency for manufactured housing complaints is the Illinois Department of Public Health, Manufactured Home Community Program. They investigate complaints and enforce health and safety standards in mobile home parks.
