Oak Park, IL Rental Property Rules: Rental Registration (2026)

Oak Park requires all residential rental properties to be registered and licensed under the village's Residential Landlord License program. Property owners must apply for a license through the Development Customer Services Department, pay the annual licensing fee, and undergo property inspections. Inspections verify compliance with building, fire, and housing codes including smoke detectors, carbon monoxide detectors, electrical systems, plumbing, heating, and structural integrity. The village inspects rental properties on a regular cycle — typically every 3-4 years for compliant properties, more frequently for properties with violations. New rental properties and properties that change tenants must be inspected before occupancy. Landlords must provide tenants with required disclosures including lead paint information for pre-1978 buildings. The license must be renewed annually and the fee varies based on the number of units. The village maintains a registry of all licensed rental properties. Landlords must provide emergency contact information and maintain adequate insurance. Contact Development Customer Services at (708) 358-5440 for licensing requirements.
