Historic Preservation

The Village Council adopted a new Historic Preservation Ordinance on December 15, 2015.  The new ordinance was the result of extensive community participation at both the Architectural Design Review Board (ADRB) / Ad Hoc Subcommittee on Historic Preservation meetings and Village Council meetings.   

The new ordinance includes two types of historic districts: contiguous and thematic.

contiguous district would consist of two or more adjacent properties. In order for the nomination to be considered by the Village, 51% of the property owners within the proposed district must agree to apply. Once established, the character of the properties would be preserved through a Certificate of Appropriateness process which would require certain external modifications or improvements which are visible from the street to be approved by the ADRB.

While the contiguous district was part of the previous ordinance, the concept of a thematic district is new. This type of district would allow the owners of properties of similar character or significance to form a historic district whether the properties are adjacent to each other or located throughout the Village. For example, the owners of Victorian-style homes located throughout the Village could form a district. A thematic district application requires consent by 100% of owners.

The new ordinance also reduces regulations that deter participation in preservation efforts, such as regulations regarding the Certificate of Appropriateness. Under the new ordinance, only exterior changes or modifications that require a building permit (excluding doors or windows) or are visible from a street would be subject to the Certificate of Appropriateness.

The ordinance maintains provisions to protect property owners from allowing others, including the Village, to enact preservation regulations without the owner's consent,  The ordinance also maintains the Architectural Design Review Board as the Village’s Historic Preservation Commission 

Is your home a Historic Landmark?

Residents using the Village's new Historic Resource Application need only to enter an address to find out if their property is a potential Historic Landmark in Downers Grove.

The application provides historic information identified in three previous surveys:

  • The early 1970s State of Illinois Historic Architectural and Archaeology Resources Geographic Information System (HAARGIS) survey.
  • The 2009 Village Historic Preservation Plan identifies HAARGIS buildings, designated Downers Grove Historical Society properties, and Sears Homes.
  • The 2013 Village Historic Building Survey surveyed 865 properites in Denburn Woods, Shady Lane Estates, E.H. Prince Subdivision and Maple Avenue/Main Street corridor

The Village has mapped the properties identified in these documents on this map to help property owners determine if their home is a potential Historic Landmark.

Property Tax Assessment Freeze Program

The Village was recently approved to be a part of the Property Tax Assessment Freeze Program administered by the Illinois Historic Preservation Agency (IHPA).  The free program is administered by the IHPA as a benefit to historic landmark property owners who are interested in rehabilitating their historic home.  The program can freeze the assessed value of the historic, owner-occupied, principal residence for a period of 8 years, followed by a four-year period during which the property’s assessed value steps up to an amount based upon its current market value.  This results in 12 years of reduced property taxes.  

If you are a historic landmark property owner who is thinking about rehabilitating your landmarked house and are interested in the program, contact Carol Dyson, IHPA Chief Architect and Tax Incentives Coordinator (carol.dyson@illinois.gove or  217-524-0276) in advance of your rehabilitation project.
