Duboce Triangle Historic Context Statement (2022)

StyleItalianate

Year built as surveyedCa. 1880

One of the properties the statement puts forward as a potential city landmark candidate, a list it calls 37 properties in one passage and 38 in another and prints with 38 entries; it says further research will be required to confirm any of them. Christopher VerPlanck's context statement of 2022 surveyed 552 properties in Duboce Triangle for the Duboce Triangle Neighborhood Association. Dates it gives as “Ca.” are its own estimates.
