Marion is the county seat of Williamson County in southern Illinois, with a population of roughly 17,000 residents. As a mid-sized city in a largely rural region, Marion's rental market includes single-family homes, apartments, and manufactured housing. Many renters in Marion search for answers about security deposits, eviction procedures, and what happens when a landlord refuses to make repairs — all governed by Illinois state law.
Unlike Chicago, which has its own Residential Landlord and Tenant Ordinance (RLTO), Marion has no local tenant protection ordinances. All tenant-landlord relationships in Marion are governed by the Illinois Landlord and Tenant Act, the Security Deposit Return Act (765 ILCS 710), the Security Deposit Interest Act (765 ILCS 715), and Illinois common law habitability standards. Understanding these state-level protections is essential for every Marion renter.
This guide explains your rights as a renter in Marion, Illinois. It is intended as general legal information only and does not constitute legal advice. Laws can change, and individual circumstances vary — consult a qualified attorney or free legal aid provider for advice specific to your situation.
Marion has no rent control, and Illinois state law expressly prohibits any municipality from enacting one. Under 765 ILCS 720, the Rent Control Preemption Act, local governments in Illinois — including cities, counties, and townships — are barred from adopting any ordinance or resolution that limits the amount a landlord may charge for rent. This preemption applies uniformly across the state, including in Marion and Williamson County.
In practical terms, this means your landlord in Marion can raise your rent by any amount, at any time, as long as they provide proper advance notice before the increase takes effect. For a month-to-month tenancy, that means at least 30 days' written notice before the new rent amount applies. There is no cap on how large the increase can be, and there is no local board or agency that reviews rent increases. Renters facing unaffordable rent hikes have the option to negotiate with their landlord or give notice to vacate before the new rate begins.
Implied Warranty of Habitability: Under Illinois common law, all landlords — including those in Marion — must maintain rental units in a habitable condition throughout the tenancy. This means the property must have functioning heat, plumbing, electrical systems, structurally sound walls and roof, and protection from weather. If a landlord fails to make necessary repairs after being notified, tenants may have remedies including rent withholding, repair-and-deduct, or lease termination, depending on the severity of the conditions. Because Marion is not covered by the Chicago RLTO, these remedies are governed by Illinois common law and any applicable lease terms.
Security Deposit Return (765 ILCS 710): The Illinois Security Deposit Return Act requires landlords who own five or more rental units to return the security deposit — along with an itemized statement of any deductions — within 30 days of the tenant vacating the unit. Failure to comply entitles the tenant to the full deposit amount plus court costs. See the Security Deposit section below for full details.
Security Deposit Interest (765 ILCS 715): Landlords who own 25 or more units and hold a deposit for more than six months must pay interest on it at a rate determined annually by the Illinois Department of Financial and Professional Regulation. This applies to many larger apartment complexes in Marion.
Notice to Terminate (735 ILCS 5/9-207): To end a month-to-month tenancy in Illinois, either the landlord or tenant must give at least 30 days' written notice before the end of a rental period. For week-to-week tenancies, seven days' notice is required. If a landlord fails to give proper notice, the tenant may have grounds to challenge the termination.
Anti-Retaliation (765 ILCS 720/1): Illinois law prohibits landlords from retaliating against tenants who report code violations, contact government agencies about housing conditions, or exercise any legal right under their lease or state law. Retaliation may include raising rent, reducing services, or attempting to evict. If a landlord retaliates within one year of a protected act, there is a rebuttable presumption of retaliation under Illinois law.
Lockout and Utility Shutoff Prohibition: Illinois law prohibits self-help evictions. A landlord may not change locks, remove doors or windows, or intentionally shut off utilities to force a tenant out. Such actions expose the landlord to legal liability and do not constitute a lawful eviction under Illinois law.
Security deposits for rentals in Marion are governed by the Illinois Security Deposit Return Act (765 ILCS 710) and the Illinois Security Deposit Interest Act (765 ILCS 715). There is no statewide cap on the amount a landlord may charge as a security deposit in Illinois, so Marion landlords may set whatever amount they choose — though the amount is often specified in the lease.
Return Deadline: Under 765 ILCS 710/2, landlords who own five or more residential units must return the security deposit (or the balance after deductions) to the tenant within 30 days after the tenant vacates the unit. If the landlord intends to make deductions for damages beyond normal wear and tear, they must provide the tenant with an itemized written statement of those deductions within the same 30-day period.
Penalty for Wrongful Withholding: If a landlord covered by the Act (owning five or more units) fails to return the deposit or provide the required itemized statement within 30 days, the tenant is entitled to recover the full deposit amount plus court costs and reasonable attorney's fees under 765 ILCS 710/2. This is a significant remedy — the tenant can sue in small claims court in Williamson County.
Interest on Deposits (765 ILCS 715): Landlords who own 25 or more residential units and hold a security deposit for more than six months are required to pay interest on the deposit. The applicable interest rate is set annually by the Illinois Department of Financial and Professional Regulation.
Normal Wear and Tear: A landlord may not deduct for ordinary wear and tear — minor scuffs, carpet worn from normal use, faded paint — only for actual damage caused by the tenant beyond normal use. Tenants should document the unit's condition with photos at move-in and move-out to protect their deposit.
In Marion, Illinois, a landlord must follow the formal legal eviction process and cannot remove a tenant through self-help methods. The eviction process is governed by 735 ILCS 5/9-101 et seq. (the Illinois Code of Civil Procedure, Evictions Article).
Step 1 — Written Notice: Before filing for eviction, the landlord must serve the tenant with the appropriate written notice:
Step 2 — Filing in Court: If the tenant does not comply with the notice, the landlord may file an eviction complaint in the Williamson County Circuit Court. The tenant will be served with a summons and given an opportunity to respond and appear at a hearing.
Step 3 — Court Hearing: Both parties appear before a judge. Tenants have the right to present defenses, such as the landlord's failure to maintain habitability, improper notice, or retaliation. If the court rules in the landlord's favor, a judgment for possession is entered.
Step 4 — Order of Possession and Enforcement: After a judgment for possession, the landlord may obtain an order directing the sheriff to remove the tenant if they do not vacate voluntarily. Only a court officer (the sheriff) may physically remove a tenant.
Self-Help Eviction Is Illegal: A landlord in Marion may not change the locks, remove the tenant's belongings, shut off utilities, or otherwise attempt to force a tenant out without going through the court process. Such actions are unlawful under Illinois law and may expose the landlord to damages.
