Cook County Zoning Ordinance

Ord. No. 01-O-30, as adopted by the County Board on November 6, 2001. Amendments are indicated by parenthetical history notes following amended provisions. The absence of a history note indicates that the provision remains unchanged from the original. Obvious misspellings and punctuation errors have been corrected without notation. For stylistic purposes, headings and catchlines have been made uniform, and the same system of capitalization, citations to state statutes, and expression of numbers in text as appears in the County Code has been used. Additions for clarity are indicated by brackets.

  • Cook County Zoning Ordinance of 2003
