The City of Crystal Lake has adopted a collection of land development regulations and published them as our Unified Development Ordinance (UDO).

A UDO is more than a collection of chapters from the zoning, subdivision, sign and tree preservation ordinances. Rather, the goal of consolidating the various ordinances into a UDO is to provide:

  • A single document rather than multiple, conflicting, ordinances.
  • A uniform set of consistent definitions.
  • Procedures that follow the normal sequences of development.
  • A coordinated system for development review and enforcement.
