Mundelein is a village in Lake County, located in Chicago's northern suburbs about 35 miles from downtown. Illinois state law (50 ILCS 825/5) prohibits local rent control, so Mundelein cannot cap rents. Chicago's Residential Landlord and Tenant Ordinance applies only within Chicago and does not extend to Mundelein or Lake County. The Illinois Security Deposit Return Act (765 ILCS 710) and Illinois common law habitability standards govern the landlord-tenant relationship in Mundelein.
Mundelein has no rent control. Illinois law preempts all local rent stabilization ordinances under 50 ILCS 825/5. Lake County also has no rent control measures. Landlords in Mundelein may raise rents freely at lease renewal. Month-to-month tenants should know they are entitled to at least 30 days' written notice before a rent increase or lease termination takes effect.
Illinois common law requires landlords to maintain rental premises in a habitable condition — functional heat, plumbing, sound structure, and freedom from pest infestation. If your landlord does not respond to repair requests, document the issue in writing and contact Lake County code enforcement for serious habitability concerns. Illinois prohibits self-help eviction: your landlord cannot change your locks or remove your belongings without going through the Lake County Circuit Court. Retaliation against tenants who report code violations or exercise legal rights is prohibited under 765 ILCS 720/1.
2025-2026 Illinois law updates: Effective January 1, 2026, the Safer Homes Act (Public Act 103-1031) requires landlords to attach the Illinois Department of Human Rights' Summary of Rights to every residential lease; House Bill 3566 (Public Act 104-0317) prohibits landlords from naming minors as defendants in an eviction action, and a violation requires dismissal of the case and allows a $1,000 penalty plus actual damages and attorney's fees; and Senate Bill 1563 allows owners to have police remove certain unauthorized occupants or squatters under the criminal trespass statute without filing a full eviction case. Separately, the Landlord Retaliation Act took effect January 1, 2025, creating a one-year presumption that adverse landlord action taken after a tenant's protected activity is retaliatory.
The Illinois Security Deposit Return Act (765 ILCS 710) requires landlords to return your deposit within 30 days of the end of your tenancy, along with an itemized statement of deductions. For residential buildings with 25 or more units, landlords must pay annual interest on deposits held more than six months. Wrongful withholding may entitle you to twice the amount withheld plus attorney's fees. Photograph your unit at move-in and move-out and provide your forwarding address in writing when you move out to start the 30-day return period.
To evict a Mundelein tenant, the landlord must serve proper written notice and file with the Lake County Circuit Court to obtain a judgment. Month-to-month tenants must receive at least 30 days' written notice before the tenancy ends. For nonpayment, landlords serve a 5-day pay-or-vacate notice. Lease violations require a 10-day notice to cure. Self-help eviction — lockouts, utility shutoffs, or removal of belongings without a court order — is illegal in Illinois. You have the right to respond to an eviction filing and appear in court.
