Mattoon is a mid-sized city in Coles County, Illinois, with a population of approximately 17,000 residents. A significant share of Mattoon households rent their homes, and many tenants are students or working families who may be unfamiliar with their legal rights under Illinois law. Common questions from Mattoon renters include how quickly landlords must return security deposits, what steps a landlord must follow before an eviction, and whether there are any local rent protections.
Illinois state law forms the foundation of tenant protections in Mattoon. The Illinois Security Deposit Return Act (765 ILCS 710) and Security Deposit Interest Act (765 ILCS 720) govern deposit handling, while the statewide preemption statute (765 ILCS 720/1) bars any municipality from enacting rent control. Mattoon has not adopted its own residential landlord-tenant ordinance, so renters here rely entirely on state statutes and Illinois common law.

Mattoon has no rent control, and Illinois law prohibits it. Under 765 ILCS 720/1, the Illinois Rent Control Preemption Act, no Illinois municipality — including Mattoon — may enact any ordinance, resolution, or regulation that controls or limits the amount of rent charged for private residential property. This statewide preemption applies regardless of local need or city council preference.
In practice, this means a landlord in Mattoon can raise your rent by any amount at the end of a lease term or with proper notice on a month-to-month tenancy. There is no cap on rent increases and no requirement that increases be tied to inflation, operating costs, or any other index. Once your current lease expires, your landlord is free to offer renewal at a higher rent, and you can accept, negotiate, or choose to vacate.
Because there is no rent stabilization or just-cause requirement for rent increases in Mattoon, tenants should carefully review lease renewal terms and document all communications with their landlord in writing. If you believe a rent increase is being used as retaliation for reporting code violations or asserting other legal rights, that may constitute illegal retaliation under 765 ILCS 720/1 — a separate issue addressed below.
Illinois state law provides several important protections for Mattoon renters even in the absence of a local ordinance.
Implied Warranty of Habitability: Illinois courts recognize a common-law implied warranty of habitability in residential leases. Landlords must maintain rental units in a condition fit for human habitation — including functional heating, plumbing, electrical systems, and structural integrity. If a landlord fails to make necessary repairs after reasonable notice, tenants may have remedies including rent withholding or lease termination, though Illinois law outside of Chicago does not provide a simple statutory rent-withholding procedure. Tenants in Mattoon should document repair requests in writing and consult legal aid before withholding rent.
Security Deposit Rules (765 ILCS 710 & 765 ILCS 720): The Illinois Security Deposit Return Act (765 ILCS 710) requires landlords to return a tenant's security deposit within 30 days after the tenancy ends, accompanied by an itemized statement of any deductions for damages beyond normal wear and tear. The Illinois Security Deposit Interest Act (765 ILCS 720) requires landlords who hold deposits on residential properties with 25 or more units to pay interest on those deposits. Failure to comply can result in the tenant recovering the deposit plus damages.
Notice to Terminate Tenancy: Under Illinois common law and practice, a landlord must give at least 30 days' written notice to terminate a month-to-month tenancy. Similarly, a tenant wishing to vacate must give 30 days' written notice. Fixed-term leases expire on their own terms unless renewed.
Anti-Retaliation Protections (765 ILCS 720/1): Illinois law prohibits landlords from retaliating against tenants who report housing code violations to government authorities, file complaints, or exercise other legally protected rights. Prohibited retaliatory acts include eviction, rent increases, and reduction of services. If a retaliatory action follows within a reasonable time after protected activity, the tenant may have a legal defense or claim.
Prohibition on Self-Help Eviction: Illinois law prohibits landlords from using self-help eviction tactics such as changing locks, removing doors or windows, or shutting off utilities to force a tenant out. A landlord must obtain a court judgment and follow the formal eviction process. Tenants subjected to self-help eviction may have claims for actual damages and other relief under Illinois law.
Security deposit rules in Mattoon are governed by Illinois state law. There is no statutory cap on the amount a landlord may charge as a security deposit for residential units in Illinois outside of Chicago, so landlords in Mattoon can set any deposit amount they choose — typically 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 within 30 days after the tenant vacates the unit, accompanied by an itemized written statement of any deductions. Deductions are only permitted for unpaid rent and damages beyond normal wear and tear — routine cleaning, painting, or minor wear are generally not deductible.
Interest on Deposits: If the rental property has 25 or more units, the landlord must pay interest on the security deposit in accordance with the Illinois Security Deposit Interest Act (765 ILCS 720). Smaller properties are not subject to this interest requirement.
Penalties for Non-Compliance: If a landlord in Mattoon fails to return the deposit or provide an itemized statement within the 30-day deadline, the tenant may be entitled to recover the full security deposit plus damages under 765 ILCS 710/1. Tenants who believe their deposit was wrongfully withheld should send a written demand letter and, if unresolved, may pursue a claim in Coles County small claims court. Keeping move-in and move-out documentation — including dated photographs — is essential to supporting a deposit claim.
Landlords in Mattoon must follow Illinois law when seeking to evict a tenant. Self-help eviction — such as changing locks, removing belongings, or shutting off utilities — is illegal, and tenants subjected to such tactics may have legal recourse.
Step 1 — Written Notice: Before filing for eviction, a landlord must serve the tenant with proper written notice. The type and length of notice depend 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 action (formerly called a forcible entry and detainer action) in Coles County Circuit Court under 735 ILCS 5/9-201 et seq. The tenant will be served with a summons and given an opportunity to appear and respond.
Step 3 — Court Hearing: Both parties appear before a judge. Tenants have the right to present defenses, including improper notice, retaliation, or landlord failure to maintain habitability. If the court rules in the landlord's favor, it will enter a judgment for possession.
Step 4 — Enforcement: After a judgment for possession is entered, the landlord may request a writ of possession. A sheriff's deputy — not the landlord — carries out the physical removal of the tenant if necessary. A landlord who removes a tenant without a court order may be liable for damages.
No Just Cause Requirement: Mattoon has no just-cause eviction ordinance. At the end of a lease term, a landlord is not required to state a reason for non-renewal, provided proper notice is given.
