Lake Forest is an affluent city in Lake County, Illinois, situated along the North Shore of Lake Michigan approximately 30 miles north of Chicago. While the city is known primarily for its single-family homes and historic estates, a portion of residents rent apartments, condominiums, and townhomes. Renters in Lake Forest most commonly seek guidance on security deposit returns, landlord repair obligations, and their rights when facing eviction.
Because Lake Forest has enacted no tenant-protection ordinances beyond Illinois state law, renters here rely entirely on the statewide framework: the Security Deposit Return Act (765 ILCS 710), the Security Deposit Interest Act (765 ILCS 715), anti-retaliation protections (765 ILCS 720), and the Illinois Forcible Entry and Detainer Act (735 ILCS 5/9-101 et seq.). Understanding these statutes is the foundation of knowing your rights as a Lake Forest renter.

Lake Forest has no rent control, and Illinois state law makes it impossible for the city to adopt one. The Illinois Rent Control Preemption Act, codified at 765 ILCS 720/5, explicitly prohibits any unit of local government — including home-rule municipalities — from enacting, maintaining, or enforcing any ordinance or resolution that controls or limits the amount of rent charged for leasing private residential property. This statewide preemption has been in effect since 1997 and applies equally to Chicago, Evanston, and every other Illinois municipality, including Lake Forest.
In practical terms, this means a Lake Forest landlord may raise rent by any amount at the end of a lease term or upon proper notice during a month-to-month tenancy. There is no cap on annual increases, no requirement to justify a rent hike, and no city agency that reviews or approves rent levels. Tenants who receive a rent increase they cannot afford generally have two options: negotiate with the landlord or choose not to renew their tenancy after receiving proper notice.
Illinois provides several important statewide protections that apply to every renter in Lake Forest regardless of the absence of local ordinances.
Security Deposit Return (765 ILCS 710): Within 30 days after a tenancy ends and the tenant vacates, the landlord must return the security deposit, along with any accrued interest, minus any itemized deductions for damage beyond normal wear and tear. The landlord must provide a written, itemized statement of any deductions. Failure to comply entitles the tenant to recover the deposit plus damages as outlined in the statute.
Security Deposit Interest (765 ILCS 715): Landlords who hold a security deposit for more than six months on a residential property containing 25 or more units must pay interest on the deposit annually. The interest rate is set by the Illinois Department of Financial and Professional Regulation each year.
Habitability: Under Illinois common law, landlords have an implied warranty of habitability requiring them to maintain rental units in a condition fit for human habitation. This includes functioning heat, plumbing, structural safety, and freedom from serious pest infestations. Tenants may have remedies including rent withholding or repair-and-deduct in certain circumstances, though consulting an attorney before exercising these remedies is strongly advised.
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 issues, or exercising any right protected by law. Retaliatory acts include eviction, rent increases, reduction of services, or harassment. A tenant facing retaliation may assert it as a defense in eviction proceedings or pursue an independent claim.
Lockout & Utility Shutoff Prohibition (735 ILCS 5/9-101): Illinois law requires landlords to obtain a court judgment before removing a tenant. Changing locks, removing doors or windows, or shutting off utilities to force a tenant out without a court order is an illegal self-help eviction. Tenants subjected to such conduct may seek emergency relief in court.
Notice Requirements: For month-to-month tenancies, either party must give at least 30 days written notice before the end of a rental period to terminate the tenancy. For non-payment of rent, landlords must provide a 5-day written notice to pay or vacate before filing for eviction (735 ILCS 5/9-209). For lease violations other than non-payment, a 10-day notice to cure or vacate is typically required (735 ILCS 5/9-210).
Illinois does not impose a statewide cap on the amount a landlord may charge for a security deposit in Lake Forest or elsewhere in the state. Landlords may require any deposit amount, though market norms in most areas range from one to two months' rent.
Return Deadline: Under the Illinois Security Deposit Return Act (765 ILCS 710/1), a landlord must return the security deposit — along with any interest owed — within 30 days after the tenant vacates the unit and the tenancy terminates. If the landlord intends to make deductions for damages beyond normal wear and tear, the landlord must provide the tenant with a written itemized statement of those deductions and any supporting receipts or invoices within the same 30-day period.
Penalty for Wrongful Withholding: If a landlord willfully fails to return the deposit or provide the required itemized statement within 30 days, the tenant is entitled to recover the amount of the security deposit, plus damages, costs, and reasonable attorney's fees under 765 ILCS 710/1. Tenants should document the condition of the unit at move-out with dated photographs and request written confirmation of the return of keys or possession.
Interest on Deposits (765 ILCS 715/1): For buildings with 25 or more units, landlords must pay annual interest on security deposits held for more than six months. The applicable interest rate is published each year by the Illinois Department of Financial and Professional Regulation. Failure to pay required interest may entitle the tenant to deduct it from rent or recover it through other remedies.
Evictions in Lake Forest follow the Illinois Forcible Entry and Detainer Act (735 ILCS 5/9-101 et seq.). A landlord must strictly follow each step of this process; there are no shortcuts, and self-help eviction is illegal.
Step 1 — Written Notice: The landlord must serve the tenant with a written notice appropriate to the reason for eviction. For non-payment of rent, the landlord must provide a 5-Day Notice to Pay Rent or Quit (735 ILCS 5/9-209). For a lease violation other than non-payment, the landlord must serve a 10-Day Notice to Cure or Quit (735 ILCS 5/9-210). For termination of a month-to-month tenancy without cause, the landlord must give at least 30 days written notice before the end of the rental period.
Step 2 — Filing in Court: If the tenant does not comply with the notice — by paying rent, curing the violation, or vacating — the landlord may file an eviction complaint in the Lake County Circuit Court. Lake Forest is served by the Lake County courthouse in Waukegan, Illinois.
Step 3 — Hearing: The court schedules a hearing at which both parties may present evidence. If the court finds in favor of the landlord, it issues an Order of Possession. Tenants have the right to appear and contest the eviction, raise defenses (such as retaliation or habitability), and request a continuance if needed to obtain legal representation.
Step 4 — Enforcement: Only a court-issued Order of Possession and the involvement of the Lake County Sheriff's Office may physically remove a tenant. A landlord who removes a tenant's belongings, changes locks, or shuts off utilities to force a tenant out without a court order commits an illegal self-help eviction under 735 ILCS 5/9-101 and may be liable for damages. Tenants facing an illegal lockout may seek an emergency court order to be restored to possession.
No Just Cause Requirement: Lake Forest has no just cause eviction ordinance. At the end of a fixed-term lease, a landlord may decline to renew for any lawful reason (or no reason at all), provided proper notice is given. The sole exception is that a landlord may not refuse to renew or evict a tenant for retaliatory or discriminatory reasons.
