Mount Vernon is a city of roughly 14,000 residents in Jefferson County in southern Illinois. Like many mid-sized Illinois cities outside of Chicago, a significant share of Mount Vernon households rent their homes, and those renters rely entirely on Illinois statewide tenant protections — there are no additional local ordinances in effect. Understanding those state laws is essential for anyone leasing an apartment, house, or mobile home in the area.
The most common questions Mount Vernon renters ask involve security deposit returns, repair obligations, and what happens when a landlord tries to evict a tenant. Illinois law addresses all of these issues through statutes including the Security Deposit Return Act (765 ILCS 710), the Landlord Retaliation Act (765 ILCS 720), and the Forcible Entry and Detainer Act (735 ILCS 5/9). Knowing your rights under these laws can help you respond effectively to landlord disputes.

If you are facing an eviction, deposit dispute, or habitability problem, consult a licensed Illinois attorney or contact a legal aid organization for guidance specific to your circumstances.
Mount Vernon has no rent control ordinance, and Illinois state law makes it impossible for the city to enact one. The Illinois Rent Control Preemption Act (765 ILCS 720/1) explicitly prohibits any unit of local government — including cities, counties, and townships — from enacting, maintaining, or enforcing any ordinance or resolution that would regulate the amount of rent charged for privately owned residential or commercial property.
In practical terms, this means a landlord in Mount Vernon can raise your rent by any amount, at any time, as long as proper advance notice is given — typically 30 days for a month-to-month tenancy. There is no cap on how much rents can increase, and no city agency reviews or approves rent hikes. If your lease has a fixed term, the landlord cannot raise rent until that term expires, but once it does, the landlord is free to set a new rental amount at market rate.
Renters in Mount Vernon should be aware that this statewide preemption is firm and has been in place since 1997. No legal challenge at the local level can override it. If rent affordability is a concern, tenants may wish to explore housing assistance programs through Jefferson County or the Illinois Housing Development Authority (IHDA).
Implied Warranty of Habitability: Under Illinois common law, all residential landlords — including those in Mount Vernon — must maintain rental units in a habitable condition throughout the tenancy. This means the property must have working heat, plumbing, structurally safe walls and ceilings, and freedom from pest infestations. If a landlord fails to maintain habitability after written notice, Illinois courts have recognized tenant remedies including rent withholding and repair-and-deduct, though tenants should consult an attorney before using these remedies as the procedures must be followed carefully.
Security Deposit Protections: The Illinois Security Deposit Return Act (765 ILCS 710/1) requires landlords who own 5 or more rental units to return a tenant's security deposit — or provide an itemized written statement of deductions — within 30 days of the tenant vacating the unit. Failure to comply can result in the tenant recovering the wrongfully withheld portion plus court costs. The Illinois Security Deposit Interest Act (765 ILCS 710/2) requires landlords with 25 or more units to pay interest on deposits held longer than six months.
Notice Requirements: For month-to-month tenancies, Illinois law (735 ILCS 5/9-207) requires at least 30 days written notice from either the landlord or the tenant to terminate the lease. For week-to-week tenancies, 7 days notice is required. These are minimum requirements; a written lease may specify longer notice periods.
Anti-Retaliation Protections: The Illinois Landlord Retaliation Act (765 ILCS 720/1) prohibits landlords from retaliating against tenants who report housing code violations to a government agency, request legally required repairs, or organize with other tenants. Retaliation can include rent increases, eviction notices, or reduction of services. A landlord action taken within 12 months of a protected act may be presumed retaliatory, and a tenant who prevails may be entitled to actual damages and attorney's fees.
Prohibition on Self-Help Eviction: Illinois law (735 ILCS 5/9-101 et seq.) requires landlords to go through the court system to remove a tenant. A landlord in Mount Vernon cannot legally change your locks, remove your belongings, or shut off utilities to force you out. Such actions constitute an illegal self-help eviction and may entitle the tenant to damages.
Illinois does not set a statewide cap on the amount a landlord may charge for a security deposit, so landlords in Mount Vernon may request any amount they choose. However, once a deposit is paid, specific rules govern how it must be handled and returned.
Under the Illinois Security Deposit Return Act (765 ILCS 710/1), landlords who own 5 or more residential units must return the security deposit — or deliver to the tenant an itemized statement of deductions for damages beyond normal wear and tear, along with any remaining balance — within 30 days after the tenant vacates the unit. If the landlord intends to make deductions, the itemized statement must be accompanied by paid receipts or estimates for the repair work within 30 days (or within 14 days of receiving such bills, but no later than 60 days after the tenant vacates).
A landlord who fails to comply with the 30-day return requirement forfeits the right to withhold any portion of the deposit. The tenant may recover the full deposit amount plus court costs. Intentional withholding beyond the statutory period can expose the landlord to additional damages as determined by the court.
The Illinois Security Deposit Interest Act (765 ILCS 710/2) separately requires landlords owning 25 or more units to pay annual interest on security deposits held for more than six months. The interest rate is set each year by the Illinois Department of Financial and Professional Regulation. Landlords who fail to pay required interest must return the entire deposit upon demand.
To protect yourself, always obtain a receipt for your security deposit, document the unit's condition with dated photographs at move-in and move-out, and provide your forwarding address in writing when you vacate so the landlord can return the deposit to the correct location.
Eviction in Mount Vernon, like all of Illinois, is a court-supervised process governed by the Forcible Entry and Detainer Act (735 ILCS 5/9-101 through 9-321). A landlord cannot remove a tenant without following each required step — cutting corners is illegal and can expose the landlord to liability.
Step 1 — Written Notice: Before filing in court, the landlord must serve the tenant with a proper written notice. The type and duration of notice depends on the reason for eviction:
• Non-payment of rent: 5-day written notice to pay rent or vacate (735 ILCS 5/9-209).
• Lease violation other than non-payment: 10-day written notice to cure the violation or vacate (735 ILCS 5/9-210).
• Termination of month-to-month tenancy (no fault): 30-day written notice (735 ILCS 5/9-207).
The notice must be delivered to the tenant personally, left with a household member, or posted on the door and mailed, depending on circumstances.
Step 2 — Court Filing: If the tenant does not comply with the notice, the landlord may file an eviction complaint in the Jefferson County Circuit Court. The tenant will be served with a summons and given the opportunity to appear and contest the case.
Step 3 — Hearing: Both parties present their case before a judge. Tenants have the right to raise defenses such as failure to maintain habitability, retaliation, improper notice, or acceptance of rent after the notice period. If the landlord prevails, the court issues an order of possession.
Step 4 — Enforcement: Only a Jefferson County Sheriff's deputy may physically remove a tenant pursuant to a valid court order. A landlord who attempts to remove a tenant without a court order — by changing locks, removing doors, shutting off utilities, or removing the tenant's belongings — commits an illegal self-help eviction in violation of 735 ILCS 5/9-101. Tenants subjected to self-help eviction may seek emergency injunctive relief and damages in court.
Mount Vernon does not have a just cause eviction ordinance. A landlord may choose not to renew a lease for any legal reason, provided proper notice is given.
