Structures located within the unincorporated areas of DuPage County will be considered to be of historical/architectural importance if they meet the following criteria:

A structure is listed on the National Register of Historical Places, or

A structure is listed on the Illinois Register of Historic Places, or

A structure is at least fifty (50) years old and meets one of the following criteria:
  1. Unique Architecture.

    To be considered architecturally unique, a structure must meet at least one of the following characteristics:

    Physical features or traits that are fully integrated with the lines and massing of the overall style of the structure. (Add-on features that are not in keeping with the overall style will not make a structure architecturally important.)

    It is a specimen of its type or period of construction. Such a structure must be a major building of its type. (A structure is not architecturally important only if it is the only building of a type or style.)

    It is the work of a master. A master is a figure of generally recognized greatness in a field, a known craftsman of consummate skill.
  2. Historic Event

    A structure must be associated with an historic event or trend, and then it must retain historic integrity. The property's association with the event must itself be considered important as well. (Mere association with historic events or trends, in and of itself, does not qualify a structure as historically important.)
  3. Persons With Historical Contribution

    A structure must be associated with individuals who have made an important contribution to history. This association must be documented and demonstrably important in the local, state or national context.
In the case of the conversion of an apartment building into condominium units, the County shall have the right to inspect the apartment building prior to the conversion to condominium units and require that each proposed condominium unit, as well as all common areas, comply with the current life safety, building and zoning codes and ordinances of DuPage County.

Life safety features shall include but are not limited to the installation of, or improvements to, the following:
  1. Fire sprinkler system
  2. Fire alarm system
  3. Environmental barriers and accessibility
  4. Exiting
  5. Means of egress lighting
A property which contains structures, excepting those newly constructed and intended for condominium ownership, which are, or have previously been, wholly or partially occupied before recording of condominium instruments by persons other than those who have contracted for the purchase of condominiums.
