The Homer, NY Historic District is one of the earliest (early 1970s) to apply for and get Historic Register status. Forms were provided and houses were assigned to members of the newly formed Landmark Society to be studied and reported on. Photos were also submitted.
Mary Alice Bellardini, who was/is one of those most involved in this effort says it was not a difficult task but you did need to collect a lot of information and it is time consuming. The work involved providing copies of deeds, visits to the County Clerk's Office for houses or buildings that may not have those historic documents, talking with older residents who may have special recollections about the structure, and maybe even a tour of the property by the owner who may know background on it. Sometimes visiting with an architect is important. Whatever needs to be done must be to get things as correct as possible in establishing the founding date should be done carefully and thoroughly.
Hope this helps. Best of luck in your efforts.
Our area and our house was on the NM historical registry before we bought it. The restrictions were very light and as long as we stayed within the original look we could do just about what we wanted.
Thanks for the replies! I am right across the way from a historic district but it stops before my house. Ironically, according to my abstract, that district originally included my street but it was moved a long time ago.
I would be interested in hearing from anyone who initiated the process for their house and to hear any pros or cons to it. There are many new builds in my neighborhood where the old ones have been torn down so I am working hard to bring back and highlight my home's original architectecture.
