The statement is reconnaissance-level and says inclusion in it is not a judgement on a building's worthiness for preservation. It records the row as single-storey end-gable dwellings with entry porch and bay window, and names Nelson's Hartford Street houses as a concentration of developer housing worth studying as a potential historic district. The recommendations print the range as 2-64 Hartford; the builder table prints it as 20-64."
