Blue Island is a south suburban city in Cook County, Illinois, with a significant renter population that relies primarily on Illinois statewide tenant protections. As a smaller municipality located just south of Chicago, Blue Island renters often ask whether Chicago's stronger tenant ordinances — such as the Chicago Residential Landlord and Tenant Ordinance (RLTO) — apply to them. They do not: the Chicago RLTO applies only within the City of Chicago's boundaries, and Blue Island has not enacted its own local tenant protection ordinance.
Instead, Blue Island renters are governed by Illinois state law, including the Security Deposit Return Act (765 ILCS 710), the Security Deposit Interest Act (765 ILCS 720), anti-retaliation statutes, and well-established common law habitability standards. These protections cover core renter concerns: getting your security deposit back, living in a safe and habitable unit, receiving proper notice before eviction, and being free from landlord retaliation for asserting your legal rights.

Blue Island has no rent control, and landlords may raise rent by any amount with proper notice. This is not merely a local policy choice — Illinois state law explicitly prohibits municipalities from enacting rent control ordinances. Under 765 ILCS 720 (the Rent Control Preemption Act), no county, municipality, or other unit of local government in Illinois may enact, maintain, or enforce any ordinance or resolution that limits the amount of rent charged for privately owned residential or commercial property. This preemption applies statewide, meaning Blue Island, Cook County, and all other Illinois jurisdictions outside of any exemption are barred from regulating rent levels.
In practice, this means your landlord can increase your rent to any amount when your lease term expires or, for month-to-month tenancies, with at least 30 days' written notice before the next rent due date. There is no cap on rent increases, no required justification, and no process for challenging the increase amount under Illinois law. Your only protection is the notice requirement — a landlord cannot raise your rent mid-lease without your written agreement, and cannot raise rent on a month-to-month tenancy without providing the legally required advance written notice.
Illinois state law provides Blue Island renters with several important protections that apply regardless of whether a local ordinance exists.
Security Deposit Rules (765 ILCS 710 & 765 ILCS 745): Landlords who hold a security deposit must return it within 30 days after the tenant vacates, along with a written, itemized statement of any deductions. Deductions are only permissible for unpaid rent and actual damages beyond normal wear and tear. Failure to comply with these requirements can expose the landlord to liability for the full deposit amount plus damages.
Habitability (Illinois Common Law & 765 ILCS 735): Illinois recognizes an implied warranty of habitability in all residential leases. Landlords must maintain rental units in a condition that is safe, sanitary, and fit for human habitation — including functional heating, plumbing, electrical systems, and structural integrity. If a landlord fails to repair a serious habitability defect after reasonable notice, tenants may have remedies including repair-and-deduct or rent withholding, though the specific procedures under Illinois law should be followed carefully.
Notice to Terminate Tenancy (735 ILCS 5/9-207): For month-to-month tenancies, Illinois law requires at least 30 days' written notice from either the landlord or tenant before the tenancy can be terminated. For week-to-week tenancies, 7 days' notice is required. Neither party may terminate a fixed-term lease early without cause unless the lease provides for it.
Anti-Retaliation (765 ILCS 720/1): Landlords are prohibited from retaliating against tenants who report housing code violations to government authorities, join a tenant union, or assert any legal right under Illinois law. Retaliation can include rent increases, eviction threats, service reductions, or harassment. A tenant who faces retaliation may assert it as a defense in court and may be entitled to remedies including damages.
Prohibition on Self-Help Eviction (735 ILCS 5/9-101 et seq.): Illinois law requires landlords to obtain a court judgment before removing a tenant. A landlord may not change the locks, remove doors or windows, shut off utilities, or take any other self-help action to force a tenant out. All evictions must proceed through the Cook County court system.
Blue Island landlords who collect a security deposit are governed by the Illinois Security Deposit Return Act (765 ILCS 710) and the Illinois Security Deposit Interest Act (765 ILCS 745).
No Statewide Cap: Illinois state law does not cap the amount a landlord may charge for a security deposit. The amount is set by the lease agreement. Tenants should document the deposit amount paid and obtain a written receipt.
Return Deadline: Under 765 ILCS 710/1, landlords must return the security deposit — along with a written, itemized list of any deductions — within 30 days after the tenant surrenders possession of the unit (vacates and returns keys). If the landlord intends to make deductions, the itemized statement must be provided within that same 30-day window.
Allowable Deductions: Deductions are permitted only for unpaid rent and for physical damage to the unit beyond normal wear and tear. Landlords may not deduct for routine cleaning or pre-existing conditions. Tenants should conduct a move-in and move-out inspection and document the unit's condition with photographs.
Penalty for Wrongful Withholding: If a landlord wrongfully withholds all or part of a security deposit without providing the required itemized statement, the tenant may be entitled to recover the full amount wrongfully withheld, plus damages, under 765 ILCS 710/1. Tenants should send a written demand letter and, if unresolved, may pursue the claim in Cook County small claims court.
Interest on Deposits: Under 765 ILCS 745, landlords who hold security deposits for more than six months for residential buildings with 25 or more units must pay interest on the deposit. The applicable interest rate is set annually by the Illinois Department of Financial and Professional Regulation.
All evictions in Blue Island must follow Illinois law and be processed through Cook County Circuit Court. A landlord has no legal right to remove a tenant through self-help methods. Below is the step-by-step eviction process that applies in Blue Island.
Step 1 — Written Notice (735 ILCS 5/9-207 & 5/9-209): Before filing in court, the landlord must serve the tenant with a written notice. The type and duration of notice depends on the reason for eviction:
Step 2 — Filing in Court: If the tenant does not comply with the notice, the landlord may file an eviction lawsuit (formerly called a forcible entry and detainer action) in the Cook County Circuit Court. The tenant will be served with a summons and given the opportunity to appear and present a defense.
Step 3 — Court Hearing: Both parties may present evidence and arguments before a judge. Tenants may raise defenses including improper notice, retaliation, habitability failures, or payment of rent. If the landlord prevails, the court issues an order for possession.
Step 4 — Enforcement by Sheriff: Only a Cook County Sheriff's deputy may physically remove a tenant after a court order for possession is entered and a Writ of Possession is issued. The landlord has no authority to personally remove the tenant or their belongings.
Self-Help Eviction is Illegal: Under Illinois law (735 ILCS 5/9-101), a landlord who changes the locks, removes doors, shuts off utilities, or otherwise attempts to force a tenant out without a court order is committing an illegal self-help eviction. Tenants who experience this should contact law enforcement and seek immediate legal assistance.
No Just Cause Requirement: Illinois does not require landlords to have a specific reason (just cause) to decline to renew a lease at the end of its term. However, proper advance notice must still be given, and eviction must still proceed through the courts if the tenant does not vacate voluntarily.
