Land Use & Zoning

In Illinois, an 'annexation' occurs when:

AA property is rezoned from residential to commercial use
BA municipality incorporates additional adjacent territory into its corporate boundaries✓ Correct
CA county takes over zoning authority from a municipality
DPrivate land is dedicated for public use

Explanation

Annexation is the process by which a municipality extends its corporate boundaries to incorporate adjacent unincorporated territory. In Illinois, annexation can occur voluntarily (property owner petitions) or through ordinance under specified conditions. Once annexed, the territory becomes subject to municipal zoning, ordinances, and services. Developers often seek annexation to access municipal utilities (water, sewer) in exchange for development agreements.
