Bill Summary · HB 1821

Legislative bill overview

HB 1821 establishes regulatory controls over advertising displays along Illinois highways. The bill, sponsored by Representatives Eva-Dina Delgado, Cristina Castro, and Barbara Hernandez, became law in August 2025. It creates standards and restrictions governing billboard placement, size, lighting, and maintenance on highway corridors throughout the state.

Why is this important

Highway advertising regulation affects both aesthetic quality of public roadways and economic interests of outdoor advertising companies. The law impacts local communities' visual environment, tourism experiences, and property values while also determining revenue opportunities for advertisers and landowners who host billboards.

Potential points of contention

  • Advertising industry costs: Compliance requirements and restrictions on new billboards may increase operational expenses or limit expansion, potentially affecting small advertising businesses disproportionately
  • Property owner rights: Landowners with existing advertising contracts may face restrictions on rental income if regulations limit billboard types, sizes, or lighting on their properties
  • Enforcement and jurisdiction: Unclear which state agencies enforce compliance and how disputes between municipalities, property owners, and advertisers are resolved under the new framework
