Outdoor lights that shine onto neighboring properties causing unreasonable disturbance may be the subject of enforcement action.

Residential properties are expected to direct outdoor lighting downward and away from neighboring properties. The Department of Building and Zoning responds to complaints about light trespass in unincorporated areas. Illinois common law also provides remedies for light nuisance through the courts.
