PLAQUING APPLICATION FORM (PDF) (click HERE)
Thank you for inquiring about the process of plaquing an historic site or structure located in McHenry County. It is our hope that the required documentation (click above for pdf or use the webform below to submit online) will provide a lasting record of the property, site and structure. For brochure addressing frequently asked questions click HERE.
Please complete as many items as possible. Not all questions will be applicable to your particular property. If you are uncertain of the meaning of any of the questions, please refer to the article below, "How to Confirm the Age of Your Home" and the reference book list. Contact the museum for any further guidance.
Please return the completed application, along with a current photograph and old photograph if available of the site or structure and copies of documentation to Historic Sites Committee, McHenry County Historical Society. P.O. Box 434, Union, IL 60180. If approved, the total cost of the plaque, approximately $120, is the responsibility of the property owner.
The application and photographs and copies of documentation will become the property of the McHenry County Historical Society. Upon receipt of the application, the committee will arrange a time to conduct a field investigation of the site. If you wish, you may make a presentation to the committee regarding the historic and/or architectural significance of the property.
Plaquing an historic site or structure is an excellent means of calling attention to the heritage of McHenry County. It is not a legal proceeding, and thus does not interfere with the buying and selling of the property. However, once plaqued, the plaque will remain with and on the structure or site...not with the owner of the property at the time of plaquing.
• Plaquing by the McHenry County Historical Society does not make the site eligible for reductions in property taxes. However, hIstoric preservation tax incentives are offered through the state and federal goverment.
• Plaquing also does not require you to open the site or structure to the public.
• Plaquing does not prohibit the owner from altering the structure or site (i.e., remodeling or additions).
However, if the alterations detract from the architectural or historic integrity of the structure or site, and upon review, the Historic Sites Committee determines that the structure or site no longer meets the Minimum Standard for plaquing, you will forfeit your privilege of displaying the plaque on the structure or site.

4. Conservation of architectural elements: The preservation of original, distinctive details and characteristics which define the aesthetic and architectural integrity of a building.

At the time of purchase, ask the sellers for any information they may have about the house: Property abstracts, Old deeds, Names of previous owners and Pictures.Old letters or papers with information pertaining to the house or any of its owners. Talk to neighbors and senior citizens in the area.
Get a legal description of the property. It will be contained in the title information. This "legal" will be used in many avenues of research.
The title company that issued the title insurance has probably run a title search on the property. A "chain of title" is necessary for house history research. It may be costly. Some local title insurance companies allow manual research in their title books free of charge.
The Recorder of Deeds office at the county courthouse has records that are open to the public. Clerks there will advise on how to use the Grantor-Grantee indices. Know the Property Identification Number and have the legal description when you go there. The Grantor books indicate the seller, and the Grantee books indicate the buyer of the property. Date of sale, quit claim deeds (QC), warranty deeds (WC), "book and page" information, and brief legal description and other legal documents may be contained on microfiche in this office.
The County Treasurer's office at the courthouse has all real estate and personal property tax records on microfilm or fiche by date, township and section number. Look for a large increase in the tax amount, indicating a rise in value (a structure added), in the "tax due" column.
The Township Assessor's office may have old records (from the late 1800's) that contain construction dates, crude floor plans, builder's names, building materials, etc. These excellent sources of information may, however, be in storage, as the offices are mostly computerized, Ask questions, and give clerks time (weeks) to find the files.
