PART A -- ADMINISTRATIVE AND INTRODUCTORY
ARTICLES
Note: These ordinances
were put on the Internet for use by Apartment Owners.
Owners of other property types must refer to the book of Cook County
Building and Environment Ordinance for information on their building
types. This site makes no money and has
no affiliation with the publisher. The site was developed
because as an apartment owner, I found it impossible to obtain any
information from the Cook County Zoning Department and Cook County
refused to put the ordinances on the internet where apartment owners
could look up the ordinances and repair their buildings BEFORE the
inspector violated them. That is why thissite does not document
every Article and if the owner needs this information - it may be
necessary to purchase the book. This book can be
purchased at:
