This map shows single-family detahed houses (as classified by the Cook County Assessor in the 2019 property tax year) that exist in Chicago within zoning districts which allow multi-family housing (this considers R, B, C, and D zoning districts with a minimum lot area per unit of 1,350 s.f. or less). Subdivide the house or replace it with an apartment building to offer more units. This map for the entire City of Chicago can be purchased.
