Mount Prospect has no rent control, and Illinois state law (50 ILCS 825/5) prohibits all Illinois municipalities from enacting any rent control or rent stabilization ordinance. This statewide preemption applies to Mount Prospect just as it does to every other Illinois community. The village board has no authority to impose any caps on rent increases.
A Mount Prospect landlord may raise rent by any dollar amount. The only procedural constraint is proper written notice — at least 30 days' written notice is required before a month-to-month tenancy can be terminated or a rent increase imposed on month-to-month tenants. Fixed-term lease tenants cannot have rent raised mid-lease unless the lease expressly permits it. Tenants have no legal mechanism to challenge the size of a rent increase under Illinois law.
Illinois state law provides Mount Prospect renters with the following core protections:
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.
Security deposit rules in Mount Prospect are governed by the Illinois Security Deposit Return Act (765 ILCS 710). Your landlord must return your full security deposit — or provide a written itemized statement of deductions — within 30 days after you vacate the unit.
Only unpaid rent and damage beyond normal wear and tear may be deducted. Routine wear and tear — minor scuffs, small nail holes, and carpet worn from ordinary use — cannot be charged to the tenant. Document the unit's condition with dated photographs at move-in and move-out to protect yourself against improper deductions.
If your building has 25 or more units, your landlord must hold your deposit in a federally insured interest-bearing account and pay you interest on the deposit annually. Provide your forwarding address to your landlord in writing when you move out to start the 30-day return deadline.
Mount Prospect landlords must follow Illinois's formal eviction process through Cook County Circuit Court. Self-help eviction is prohibited under Illinois law. For nonpayment of rent, a 5-day written notice to pay or vacate must be served before filing. For lease violations, a 10-day notice to cure or vacate applies. To terminate a month-to-month tenancy, at least 30 days' written notice is required.
If the tenant does not comply, the landlord may file an eviction action in Cook County Circuit Court. Tenants have the right to appear at the hearing and raise defenses including habitability violations, improper notice, and retaliation. A court judgment must be obtained before any order of possession is entered.
Only the Cook County Sheriff may physically remove a tenant — the landlord cannot do so independently. Illegal self-help eviction can expose the landlord to civil liability under Illinois law.
