Chicago Heights is a city of approximately 30,000 residents in southern Cook County, Illinois. A significant share of households rent their homes, and tenants here are subject to Illinois statewide landlord-tenant law rather than any citywide ordinance. Unlike the City of Chicago — which has its own Residential Landlord and Tenant Ordinance (RLTO) — Chicago Heights has not enacted supplemental local tenant protections, meaning state law sets the floor for all renter rights.
Tenants in Chicago Heights most commonly seek information about security deposit return deadlines, how to respond to eviction notices, what 'habitable conditions' means under Illinois law, and protections against landlord retaliation. Illinois law provides meaningful baseline protections on each of these topics, but it does not cap how much a landlord may raise rent or require a landlord to show 'just cause' before ending a tenancy.
This guide summarizes those statewide protections as they apply to renters in Chicago Heights. It is intended as general information only and does not constitute legal advice. Laws can change, and your specific situation may involve facts that alter the analysis. Contact a qualified attorney or free legal aid organization for guidance on your individual case.
Chicago Heights has no rent control, and Illinois state law explicitly forbids it. The Illinois Rent Control Preemption Act, codified at 765 ILCS 720, prohibits any county, municipality, or other local governmental unit from enacting, maintaining, or enforcing any ordinance or resolution that controls the amount of rent charged for leasing private residential or commercial property. This preemption applies statewide — meaning not only Chicago Heights, but every Illinois city outside of pre-existing exceptions is barred from passing rent stabilization measures.
In practical terms, this means your landlord in Chicago Heights may raise your rent by any amount at the expiration of your lease term or, for a month-to-month tenancy, with proper advance written notice. There is no percentage cap, no inflation-based limit, and no city agency that reviews or approves rent increases. If your landlord raises your rent and you choose not to accept the new rate, your option is to negotiate, move out, or — if the increase is retaliatory — assert your rights under the anti-retaliation statute (765 ILCS 720/1). Renters facing unaffordable increases should contact a legal aid organization to discuss their options.
Illinois provides several important baseline protections for renters throughout the state, including in Chicago Heights. Each is rooted in specific statutory authority.
Security Deposit Rules (765 ILCS 710 & 765 ILCS 720): Landlords must return a tenant's security deposit — along with a written, itemized list of any deductions — within 30 days after the tenant vacates the unit. If the landlord fails to comply, the tenant may be entitled to recover twice the amount of the deposit as damages under the Illinois Security Deposit Return Act (765 ILCS 710). Interest on deposits is also required in certain circumstances under 765 ILCS 710/0.01.
Implied Warranty of Habitability (Illinois Common Law & 765 ILCS 735): Landlords are required to maintain rental units in a habitable condition — meaning functional heat, plumbing, structural safety, and freedom from serious pest infestations. Illinois courts have recognized an implied warranty of habitability in residential leases. If a landlord fails to make necessary repairs after receiving written notice, tenants may have remedies including rent withholding or repair-and-deduct in limited circumstances. Tenants should consult an attorney before withholding rent.
Notice Requirements (735 ILCS 5/9-207): For a month-to-month tenancy, either party must provide at least 30 days written notice before terminating the tenancy. For nonpayment of rent, a landlord must provide a written 5-day notice to pay or vacate before filing for eviction. For material lease violations, landlords must typically provide a 10-day notice to cure or vacate under 735 ILCS 5/9-210.
Anti-Retaliation (765 ILCS 720/1): A landlord may not retaliate against a tenant for reporting code violations to a government authority, complaining to the landlord about habitability, or exercising any legal right under state or local law. Retaliatory acts include unjustified rent increases, eviction threats, and reduction of services. A tenant who proves retaliation may recover actual damages and attorney's fees.
Prohibition on Self-Help Eviction (735 ILCS 5/9-101 et seq.): A landlord may not remove a tenant from a rental unit by force, lock changes, utility shutoffs, or removal of personal property without a court order. The only lawful way to evict a tenant in Illinois is through the judicial eviction process. Self-help eviction is unlawful and may expose the landlord to civil liability.
Illinois law governs security deposits for Chicago Heights renters through two primary statutes: the Security Deposit Return Act (765 ILCS 710) and the Security Deposit Interest Act (765 ILCS 710/0.01).
Deposit Cap: Illinois state law does not impose a maximum cap on the amount a landlord may collect as a security deposit. The amount is set by negotiation between the parties and is specified in the lease agreement.
Return Deadline: After a tenant vacates, the landlord must return the security deposit — or the balance remaining after lawful deductions — within 30 days. Along with any partial refund, the landlord must provide a written, itemized statement of any deductions for damage beyond normal wear and tear (765 ILCS 710/1).
Penalty for Wrongful Withholding: If the landlord fails to return the deposit or provide the required itemized statement within 30 days, the tenant is entitled to recover twice the amount of the security deposit as damages, plus court costs and attorney's fees, under 765 ILCS 710/1. This is a significant deterrent against improper withholding.
Interest on Deposits: For buildings with 25 or more units, landlords must pay interest on security deposits held for more than six months (765 ILCS 710/0.01). The interest rate is set annually by the Illinois Secretary of State.
Practical Tips: Document the condition of the unit at move-in and move-out with photographs and a written checklist. Always provide written notice of your forwarding address so the landlord can return the deposit to the correct location. Keep copies of all correspondence.
Evictions in Chicago Heights are governed by Illinois state law, primarily the Forcible Entry and Detainer Act (735 ILCS 5/9-101 et seq.). A landlord must follow every step of the legal process — there are no shortcuts.
Step 1 — Written Notice: Before filing any court action, a landlord must serve the tenant with the appropriate written notice. The type and length of notice depends on the reason for eviction:
Step 2 — Court Filing: If the tenant does not comply with the notice, the landlord may file an eviction complaint in the Circuit Court of Cook County. The case is filed in the Eviction (Forcible Entry and Detainer) division. The landlord must pay filing fees and properly serve the tenant with a summons.
Step 3 — Court Hearing: Both parties appear before a judge. The tenant has the right to present a defense — such as that rent was paid, the notice was defective, or the landlord failed to maintain habitable conditions. If the landlord prevails, the court issues an Order for Possession.
Step 4 — Enforcement: Only after receiving a court-issued Order for Possession and an enforcement order may the landlord request that the Cook County Sheriff remove the tenant. The landlord may not personally remove the tenant or their belongings.
Self-Help Eviction is Illegal: It is unlawful under 735 ILCS 5/9-101 for a landlord to lock out a tenant, remove their belongings, shut off utilities, or otherwise force them out without a court order. A tenant subjected to self-help eviction may seek emergency relief in court and may recover damages from the landlord.
Just Cause: Chicago Heights has no just-cause eviction ordinance. A landlord may decline to renew a lease at the end of its term for any reason or no reason, provided proper notice is given.
