Clarendon Hills City Zoning Code

ARTICLE 20

4 RESIDENTIAL DISTRICTS

20.4.1 PURPOSE STATEMENTS

  1. R-1 Single Family Residential District: The R-1 Single Family Residential District is intended to accommodate single-family residential use on lots not less than nine thousand (9,000) square feet in area and widths not less than sixty feet (60’).
  2. R-2 Medium Density Residential District: The R-2 Medium Density Residential District is intended to accommodate moderate density residential use, which could take the form of a variety of building types. The R-2 Medium Density Residential District is not intended to be located in Clarendon Hill's traditional single-family neighborhoods, but rather in transitional locations adjacent to commercial/business districts. This district may also be appropriate in existing unincorporated areas where the redevelopment of existing large lot residences is needed to spur area improvement and annexation into Clarendon Hills.
  3. R-3 Multiple-Family Residential District: The R-3 Multiple-Family Residential District is intended to accommodate moderate-density, townhouse and multiple-family residential dwellings, which could take the form of apartments, condominiums, or townhouses. Single-family and two-family dwellings are not appropriate for the R-3 District, which is intended for higher density development.
