St. Charles is a growing city in Kane County, Illinois, situated along the Fox River approximately 40 miles west of Chicago. With a mix of historic neighborhoods and newer residential developments, St. Charles attracts a substantial renter population seeking proximity to the Chicago metropolitan area while living in a smaller community setting. Renters here are primarily governed by Illinois state law, without any additional local ordinances that expand upon those baseline protections.
The most common questions St. Charles renters have involve security deposit return timelines, what notice a landlord must give before ending a lease or seeking eviction, and whether landlords can raise rent without limit. Under Illinois law, renters have meaningful protections on all of these fronts — even without a local ordinance. The Illinois Security Deposit Return Act (765 ILCS 710) and the Illinois Security Deposit Interest Act (765 ILCS 710/0.01 et seq.) establish clear rules for how landlords must handle deposits, while common law and statutory protections govern habitability and anti-retaliation rights.

St. Charles has no rent control, and Illinois state law prohibits any municipality from enacting it. Under 765 ILCS 720/1, the Illinois statute titled the Rent Control Preemption Act, local governments in Illinois are expressly forbidden from enacting ordinances, resolutions, or other measures that would regulate the amount of rent charged for private residential property. This preemption applies statewide — including Kane County and St. Charles — meaning that neither the city nor the county can pass any form of rent stabilization, rent freeze, or rent increase limitation.
In practice, this means your landlord in St. Charles can raise your rent by any amount, at any time, as long as proper notice is provided before a new lease term begins or a month-to-month tenancy is renewed. There is no cap on how much rent can increase, and no requirement that a landlord justify or explain a rent increase. The only practical limit is the notice requirement: a landlord must give at least 30 days written notice before a rent increase takes effect on a month-to-month tenancy. For fixed-term leases, rent cannot increase during the lease term unless the lease itself allows for it.
Renters who are concerned about large rent increases have limited recourse under Illinois law. However, if a landlord raises rent in retaliation for a tenant reporting code violations or exercising legal rights, that increase may be challenged under the Illinois anti-retaliation statute (765 ILCS 720/1).
Illinois state law provides several important protections for renters in St. Charles. Below are the key protections and the statutes that govern them.
Security Deposit Rules (765 ILCS 710/1; 765 ILCS 710/0.01): Landlords in Illinois must return a tenant's security deposit within 30 days after the tenant vacates the rental unit. If the landlord intends to make deductions, they must provide an itemized statement of damages and receipts within 30 days. Failure to comply entitles the tenant to recover twice the amount of the deposit wrongfully withheld. For properties with 25 or more units, landlords must also pay interest on security deposits held for more than six months, at a rate set annually by the Illinois Comptroller (765 ILCS 710/0.01).
Habitability (Illinois Common Law; 735 ILCS 5/9-201 et seq.): Illinois recognizes an implied warranty of habitability, meaning landlords must maintain rental units in a condition fit for human habitation throughout the tenancy. This includes working heat, plumbing, structural integrity, and freedom from serious pest infestations. If a landlord fails to make necessary repairs after written notice, tenants may have remedies including rent withholding or repair-and-deduct, though tenants should consult legal counsel before exercising these remedies.
Notice to Terminate Tenancy (735 ILCS 5/9-207): For month-to-month tenancies, either the landlord or tenant must give at least 30 days written notice before terminating the tenancy. For week-to-week tenancies, 7 days notice is required. Notice must be in writing and, for landlord-initiated terminations, must comply with statutory requirements to be enforceable in court.
Anti-Retaliation (765 ILCS 720/1): Illinois law prohibits landlords from retaliating against tenants who report code violations to a government authority, complain to the landlord in good faith about habitability issues, or exercise any right protected under Illinois law. Prohibited retaliatory acts include rent increases, decreasing services, or attempting to evict. A tenant who proves retaliation may recover damages, attorney fees, and court costs.
Prohibition on Self-Help Eviction (735 ILCS 5/9-101 et seq.): Landlords in Illinois are prohibited from removing a tenant through self-help measures such as changing locks, removing doors or windows, or shutting off utilities. The only lawful way to remove a tenant is through the court eviction process. Violations may expose the landlord to civil liability.
Illinois law governs security deposits for St. Charles renters under the Illinois Security Deposit Return Act (765 ILCS 710/1) and the Illinois Security Deposit Interest Act (765 ILCS 710/0.01 et seq.). There is no statewide statutory cap on the amount a landlord may charge as a security deposit, so a landlord can require any amount they choose, subject to what is stated in the lease.
Return Deadline: After a tenant vacates, the landlord must return the full security deposit — or the balance remaining after lawful deductions — within 30 days. If the landlord claims deductions for damage beyond normal wear and tear, they must provide the tenant with an itemized written statement of those deductions and, for deductions over $20, attach copies of paid receipts or invoices, all within the same 30-day period (765 ILCS 710/1).
Penalty for Wrongful Withholding: If a 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 wrongfully withheld, plus reasonable attorney fees and court costs (765 ILCS 710/1). This is a significant statutory penalty designed to deter landlords from improperly holding deposits.
Interest on Deposits: For rental properties with 25 or more units, landlords must pay interest on security deposits held for more than six months. The applicable interest rate is published annually by the Illinois Comptroller under 765 ILCS 710/0.01. Most single-family homes and smaller rental properties in St. Charles will not be subject to this interest requirement, but tenants in larger complexes should be aware of it.
Practical Tip: Always document the condition of your unit at move-in and move-out with dated photographs and a written checklist. Send your forwarding address to your landlord in writing immediately upon vacating to start the 30-day clock clearly.
In St. Charles, landlords must follow the Illinois statutory eviction process and cannot remove a tenant through any self-help means. The eviction process is governed primarily by the Illinois Code of Civil Procedure (735 ILCS 5/9-101 et seq.) and plays out in the Kane County Circuit Court.
Step 1 — Written Notice: Before filing an eviction lawsuit, 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 the Eviction Complaint: If the tenant does not comply with the notice, the landlord may file an eviction complaint (formerly called a forcible entry and detainer action) in the Kane County Circuit Court. The tenant will be served with a summons and given a court date.
Step 3 — Court Hearing: Both parties appear before a judge. The tenant has 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, it issues an order of possession.
Step 4 — Enforcement: After the court issues the order, the landlord may request the Kane County Sheriff to enforce it. The sheriff provides the tenant with notice before executing the lockout. Only the sheriff — not the landlord — may physically remove the tenant.
Self-Help Eviction is Illegal: Under 735 ILCS 5/9-101, a landlord may not change locks, remove the tenant's belongings, shut off utilities, or otherwise attempt to force a tenant out without a court order. Tenants subjected to self-help eviction may sue for damages, reinstatement, and attorney fees.
No Just-Cause Requirement: Illinois does not require landlords to state a reason for declining to renew a lease at the end of a fixed term, provided they give proper notice. However, refusing to renew based on a tenant's protected class status (race, sex, religion, disability, familial status, etc.) is prohibited under the Illinois Human Rights Act (775 ILCS 5/3-102).
