Historic Preservation Commission
July 25 Meeting Canceled
The next regularly scheduled meeting will take place Thursday, Sept. 26.
What Governs Historic Preservation in Naperville
In 2011, the City of Naperville adopted a new Historic Preservation Ordinance to coincide with the Unified Recommendation and to improve residents' ability to understand the code's implementation. The City of Naperville Municipal Code requirements for Historic Preservation can be found in Title 6, Chapter 11 of the Code.
The Historic Preservation Commission also utilizes the Historic Building Design and Resource Manual that was adopted in 2010 as an educational document and a reference in considering Certificate of Appropriateness, or COAs. The manual encourages appropriate maintenance and renovations consistent with the historic architectural style, character, and scale of existing historic structures and neighborhoods. Along with the manual, the Commission references the Architectural and Historical Survey that was conducted in 2008.
Altering or Improving Historic Properties (COA Requirements)
The City of Naperville has three locally designated Landmark buildings and approximately 320 properties within a locally designated Historic District that includes part of the North Central College campus and approximately 250 residential homes. Visit the Historic District webpage to learn more about existing Landmark and Historic District structures.
For those who wish to modify or make improvements to a property that has been designated a Landmark or is located within a Historic District, in most cases a Certificate of Appropriateness (COA) will be issued authorizing plans for exterior alteration, construction, demolition or material change of a property.
Consult the COA Requirements Table that lists the summary of requirements for a COA and its associated review process. There are three categories in which COA's are given and reviewed:
In some instances, improvements to a historical property will be exempt from the COA requirements, meaning that a COA is not required and, therefore, improvements to the property do not need to go through an administrative review or a Historic Preservation Commission review.
Certain property improvements may meet requirements allowing it to receive expedited staff review and approval through the City's Fast Track Approval Process. Access the Fast Track COA Application Packet and follow the steps outlined.
Historic Preservation Commission Review
More complex improvements that are not exempt or don't meet guidelines for the Fast Track Approval Process will need to be reviewed by the Historic Preservation Commission at a public meeting. Access the Historic Preservation Commission COA Application Packet and follow the steps outlined.
Please note: Regardless of whether a COA is required or exempt, a building permit may still be required; call (630) 420-6100, option 2 for more information.
