Not true. Residents of local historic properties or historic districts renovate or enlarge their homes whenever they desire. There are no inherent restrictions placed on local historic within local historic districts; however there is a design review process. In Wilton, the design review is handled in the “Certificate of Appropriateness” process. The process helps insure that changes are made in harmony with the structure and the neighborhood. In turn, this helps to preserve the historic integrity of the structure – as well as its contribution to the streetscape.
