The boundaries of Chicago changed as areas were annexed to the city. For
example, permits dated 1898 cover only those areas
included within the city boundaries at that time. As areas were annexed to
the city, they would then be included in the building
permits. See the attached map for the city's 1871 boundaries delineated on
those of the modern city. Formerly independent villages
and towns, such as Hyde Park, Lake, and Lakeview, that were annexed in
1889, are listed separately prior to 1895.
