From genealogist to house historian isn’t a big leap, but there are some differences between researching the history of a building and researching the people who occupied it. For example, it helps to have a rudimentary knowledge of historical architecture and construction. Fortunately, a number of free online resources can help you construct house histories.
In addition to the sites listed here, run a Google search to find other resources for your locality. Deed and tax records, at least for recent years, are often on county, city or town websites. Also search state and local historical societies and libraries, and check out the state office for historical preservation. You’ll learn about architecture common in the state, and how to register your home once you’ve successfully completed your house history.
