Illinois rent increase laws in 2025 continue to shape the rights and responsibilities of both tenants and landlords, reflecting the state’s unique balance between flexibility and tenant protection. At the core, Illinois does not impose statewide rent control, which means landlords generally have the freedom to set and increase rent according to market conditions. However, several recent legal updates and longstanding requirements ensure that tenants are not left vulnerable to arbitrary or unfair treatment.
For tenants, the most important aspect to understand is that landlords cannot raise rent during the term of an active lease unless the lease itself specifically allows for midterm increases, which is uncommon in standard agreements. This means that if you sign a one-year lease, your rent remains fixed for the entire year, providing stability and predictability. Once the lease term ends, landlords may propose a rent increase for the renewal or continuation of the tenancy, but they must provide advance written notice to tenants. The amount of notice required depends on the type of tenancy: for month-to-month or short-term leases, landlords must give at least 30 days’ notice before a rent increase takes effect; for leases of one year or more, 60 days’ notice is required. The notice must clearly state the new rent amount, the effective date, and be signed by the landlord. If proper notice is not given, the rent increase may not be enforceable.
In 2025, Illinois introduced new protections to further safeguard tenants. One of the most significant changes is the updated Landlord Retaliation Act, which prohibits landlords from increasing rent, refusing to renew a lease, or taking other adverse actions in retaliation for tenants exercising their legal rights, such as reporting code violations or unsafe living conditions. If a landlord increases rent or takes action against a tenant within one year of the tenant making a complaint, there is a legal presumption that the action is retaliatory. Landlords must be able to provide a legitimate, non-retaliatory reason for their actions to rebut this presumption.
Another key update is related to rent payment options. Landlords are now prohibited from requiring tenants to pay rent exclusively through electronic means, especially if such methods impose additional fees. Tenants must be given the option to pay by check or cash without incurring extra charges. This measure aims to protect tenants, particularly those who may not have access to digital payment systems or who face financial strain from transaction fees.
Additionally, Illinois law continues to require landlords to provide written receipts for rent and security deposits, enhancing transparency and reducing disputes. Landlords must also keep properties habitable and make requested repairs within a reasonable timeframe. If they fail to do so, tenants may be able to make necessary repairs themselves and deduct the cost from their rent, though this must be done in accordance with state law.
While there is no statewide cap on rent increases, some cities, such as Chicago, have their own notice requirements for rent increases, which may be more stringent than state law. However, even in Chicago, there is no legal limit on the amount a landlord can raise the rent. Tenants should always review their lease and local ordinances to understand their specific rights and obligations.
Illinois rent increase laws in 2025 provide tenants with important protections against sudden or retaliatory rent hikes, ensure transparency in rent payments and security deposits, and maintain flexibility for landlords. While there is no rent control, the state’s updated laws and notice requirements help promote fairness and stability in the rental market, making it essential for tenants to stay informed about their rights and for landlords to comply with all legal obligations. These measures collectively aim to foster more equitable landlord-tenant relationships across Illinois.
