Both landlords and tenants should be able to deal with many legal questions and problems without a lawyer, once they understand the basics of state law. This overview of key landlord-tenant laws in Illinois will get you started.

Required Landlord Disclosures in Illinois

Under Illinois law, landlords must disclose specific information to tenants (usually in the lease or rental agreement), such as any rent concessions. For a full list, see Illinois Required Landlord Disclosures.

Illinois Security Deposit Limit and Return

Illinois state law does not limit how much a landlord can charge for a security deposit. However, it does limit when it must be returned (between 30-45 days after a tenant moves, depending on whether the tenant disputes deductions taken out of the security deposit or if an itemized statement and receipts are provided by the landlord) and sets other restrictions on deposits. See Illinois Security Deposit Limits and Deadlines for more on the subject.

Small Claims Lawsuits in Illinois

Tenants can sue landlords in small claims court for the return of their deposit, up to a dollar amount of $10,000. See Filing a Security Deposit Lawsuit in Illinois Small Claims Court for advice for tenants filing suit. Landlords defending a security deposit lawsuit should check out Illinois Landlord’s Guide to Security Deposit Disputes in Small Claims Court.

Illinois Notice Required to Raise Rent and Other Rent Rules

State law regulates several rent-related issues, including the amount of notice (at least 30 days in Illinois) landlords must give tenants to raise the rent and how much time (five days in Illinois) a tenant has to pay rent or move before a landlord can file for eviction. For details, see Illinois Termination for Nonpayment of Rent and Other Rent Rules.

Illinois Termination and Eviction Rules

State laws specify when and how a landlord may terminate a tenancy. For example, a landlord may give an Illinois tenant who has failed to abide by any term of the lease an unconditional quit notice that gives the tenant 10 days to move out before the landlord can file for eviction. See State Laws on Unconditional Quit Terminations and State Laws on Termination for Violation of Lease for details on these types of termination notices in Illinois.

Landlord Access to Rental Property, Tenant Protection Against Retaliation, and Other State Laws in Illinois

Several other landlord-tenant laws in Illinois affect both property owners and renters, including:

Where to Find Illinois Landlord-Tenant Statutes

If you want to read the text of a law itself, such as state security deposit rules, you’ll find citations in many of the articles and charts included in the State Landlord-Tenant Laws section of the Nolo site. To access the statutes, go to the Illinois Laws and Legal Information section of the Nolo site and find the link to your state laws.

If you just want to browse through the Illinois landlord-tenant law, you can find state statutes at 735 Ill. Comp. Stat. §§ 5/9-201 to 321 & 765 Ill. Comp. Stat. §§ 705/0.01 to 742/30. You can search the table of contents for the landlord-tenant statutes. Or, if you don’t know the exact statute number, you can enter a keyword that is likely to be in it, such as “nonpayment of rent.”

In addition to accessing state laws via Nolo’s website, Illinois statutes are available in many public libraries and in most law libraries that are open to the public (typically found in a county courthouse or at the state capitol or in a publicly-funded law school).

Local Ordinances Affecting Illinois Landlords and Tenants

Cities and counties often pass local ordinances, such as health and safety standards, noise and nuisance regulations, and antidiscrimination rules that affect landlords and tenants. Many municipalities have websites —just search for the name of a particular city in Illinois and then do a search when you’re on the site. For example, if you search for the service ordinance in the City of Chicago website, you’ll easily find Chicago’s Landscape Ordinance.

State and Local Government on the Net and Municode are good sources for finding local governments online. Also, your local public library or office of the city attorney, mayor, or city or county manager can provide information on local ordinances that affect landlords and tenants in Illinois.

Federal Landlord-Tenant Laws and Regulations

While most landlords and tenants will primarily be concerned with state law in Illinois, several federal laws come into play. Congress has enacted laws, and federal agencies, such as the U.S. Department of Housing and Urban Development (HUD) and the U.S. Environmental Protection Agency (EPA), have adopted regulations, covering discrimination and landlord responsibilities to disclose environmental health hazards, such as lead-based paint.

The U.S. Code is the starting place for most federal statutory research. It consists of 50 separate numbered titles, each covering a specific subject matter. Most federal regulations are published in the Code of Federal Regulations (“CFR”), also organized by subject into 50 separate titles.

To access the U.S. Code and Code of Federal Regulations online, see Nolo’s Federal Law Resources page. Also, the Cornell Legal Information Institute provides the entire U.S. Code as well as the Code of Federal Regulations. Finally, check USA.gov, the official U.S. website for government information.
