Please remember that original windows are integral to the historic character of your home. Restoration is always your best option; restoring windows is less expensive and more authentic.

All proposed window replacements for historic buildings are subject to Planning Department review and approval. For further information please go to :www.ci.ontario.ca.us/modules/showdocument.aspx?documentid=7426.

While you are working hard to preserve your home, don’t forget to check out the Model Colony Room located downstairs at the Ontario Library. It’s a wonderful resource center to obtain possible information on the history of your home, its former residents, and your neighborhood as well as the history of Ontario.
