Winnetka is an affluent North Shore village in Cook County, Illinois, home to roughly 12,000 residents. While much of Winnetka's housing stock consists of single-family homes, a notable share of residents rent apartments, condominiums, and coach houses. Renters in Winnetka frequently search for clarity on security deposit rules, what notice a landlord must give before ending a tenancy, and whether any local rent regulations apply to their lease.
Illinois state law governs nearly all landlord-tenant relationships in Winnetka. The state's Security Deposit Return Act (765 ILCS 710) sets deposit return deadlines, the Landlord and Tenant Act (765 ILCS 720) preempts local rent control, and Illinois common law imposes an implied warranty of habitability on all residential leases. Winnetka has enacted no local tenant ordinances of its own, so renters here rely entirely on the protections Illinois law provides.
This page summarizes the laws that apply to Winnetka renters as of April 2026. It is intended for general informational purposes only and does not constitute legal advice. If you have a specific legal issue, consult a licensed Illinois attorney or contact a legal aid organization listed in the Resources section below.
Winnetka has no rent control, and state law prevents it from ever enacting one. Illinois's Rent Control Preemption Act (765 ILCS 720/1) expressly prohibits any unit of local government — including villages, cities, and counties — from enacting, maintaining, or enforcing any ordinance or resolution that controls or stabilizes residential rents. This statewide preemption was enacted in 1997 and remains in full force today.
In practical terms, this means your Winnetka landlord can raise your rent by any amount at the end of a lease term or, for month-to-month tenants, with at least 30 days' written notice before the next rent due date. There is no cap on annual rent increases, no required justification for an increase, and no local board to appeal to. If you receive a rent increase notice, your options are to accept it, negotiate with your landlord, or give proper notice to vacate. No Winnetka ordinance — and no Cook County ordinance — can override the state preemption under 765 ILCS 720.
Illinois law provides a baseline set of tenant protections that apply to every residential rental in Winnetka regardless of lease terms.
Implied Warranty of Habitability: Under Illinois common law (established in Jack Spring, Inc. v. Little, 50 Ill. 2d 351 (1972)), every residential lease carries an implied warranty that the unit is fit for human habitation. Landlords must maintain essential services including heat, plumbing, structural integrity, and freedom from pest infestation. If a landlord fails to maintain habitable conditions after written notice, a tenant may have remedies including rent withholding, repair-and-deduct, or lease termination depending on circumstances.
Security Deposit Protections: The Illinois Security Deposit Return Act (765 ILCS 710/1) requires landlords who hold security deposits to return them — along with an itemized statement of any deductions — within 30 days after the tenant vacates. Landlords who own 25 or more units must also pay interest on deposits held longer than six months under the Illinois Security Deposit Interest Act (765 ILCS 710/0.01 et seq.). Wrongful withholding exposes a landlord to statutory damages described in detail in the Security Deposit section below.
Notice to Terminate Month-to-Month Tenancies: Illinois law requires either party to give at least 30 days' written notice before terminating a month-to-month tenancy (735 ILCS 5/9-207). For fixed-term leases, no renewal notice is required unless the lease specifies one, but landlords cannot remove a tenant before the lease expires without cause.
Anti-Retaliation Protection: Under 765 ILCS 720/1, a landlord may not retaliate against a tenant for complaining to a government authority about housing code violations, organizing with other tenants, or exercising any legal right. Retaliatory acts include raising rent, reducing services, or initiating eviction proceedings in response to protected activity. A tenant who proves retaliation may recover actual damages and attorney's fees.
Prohibition on Self-Help Eviction: Illinois law (735 ILCS 5/9-101 et seq.) requires a landlord to obtain a court judgment before removing a tenant. A landlord may not change locks, remove doors or windows, shut off utilities, or remove the tenant's belongings to force them out. Such conduct constitutes illegal self-help eviction and exposes the landlord to civil liability.
Illinois imposes specific deadlines and penalties on security deposit handling that apply to every Winnetka rental.
No Statutory Cap: Illinois law does not limit the amount a landlord may charge as a security deposit. Winnetka has enacted no local cap either. The deposit amount is whatever the lease states, and landlords may require first and last month's rent in addition to a security deposit.
Return Deadline — 30 Days: Under the Illinois Security Deposit Return Act (765 ILCS 710/1), a landlord must return the security deposit — or any unused portion — within 30 days after the tenant delivers possession of the unit. If the landlord intends to make deductions for damage beyond normal wear and tear, an itemized statement of damages and receipts or estimates for repair must accompany any partial return within that 30-day window.
Interest on Deposits (Large Landlords): Landlords who own 25 or more residential units in Illinois must pay annual interest on security deposits held for more than six months, at a rate set each year by the Illinois Department of Financial and Professional Regulation (765 ILCS 710/0.01). Most individual Winnetka landlords fall below this threshold, but renters in larger complexes should confirm the applicable rate.
Penalty for Wrongful Withholding: If a landlord fails to return the deposit or provide an itemized statement within the required 30 days, the tenant may sue for the amount wrongfully withheld, plus court costs and attorney's fees under 765 ILCS 710/1. Courts have interpreted this statute to award the full deposit when landlords fail to comply with procedural requirements, regardless of whether actual damage existed.
Normal Wear and Tear: A landlord may only deduct for damage beyond ordinary wear and tear. Scuffs on walls, minor carpet wear, and faded paint are generally considered normal wear and tear under Illinois case law and are not deductible from a security deposit.
Winnetka landlords must follow Illinois's judicial eviction process in full. There is no shortcut, and self-help eviction is illegal under Illinois law (735 ILCS 5/9-101 et seq.).
Step 1 — Written Notice: Before filing any court action, 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 complaint (formerly called forcible entry and detainer) in the Circuit Court of Cook County. The court will schedule a hearing, typically within a few weeks of filing.
Step 3 — Court Hearing: Both parties appear before a judge. Tenants have the right to present defenses, including improper notice, payment of rent, retaliation by the landlord, or uninhabitable conditions. If the judge rules for the landlord, the court issues an Order for Possession.
Step 4 — Enforcement by Sheriff: Only a Cook County Sheriff's deputy may physically remove a tenant from the premises pursuant to a court order. A landlord who changes locks, removes doors or windows, shuts off utilities, or removes the tenant's belongings without a court order commits illegal self-help eviction and is subject to civil liability under 735 ILCS 5/9-101 et seq.
No Just-Cause Requirement: Winnetka has no just-cause eviction ordinance. A landlord may choose not to renew a fixed-term lease for any lawful reason — or no reason at all — as long as proper notice is given. However, a landlord may never evict in retaliation for a tenant exercising legal rights (765 ILCS 720/1).
