In the month of April we’re looking at the Washington Sanitary Improvement Company (WSIC) ownership of lots on Square 552, which is bounded by 1st, P, 3rd and Q Streets NW in Washington, DC. The company, WSIC owned 1529-1551 3rd St NW (lots 49-60 ) and 1501-1523 3rd St NW (lots 120-131). This is the last part covering lots 49-60.
In the last post I skipped to what was 1551 3rd St NW (lot 60), which is now 240 Q St NW, and condos.
So the pattern is 1529 3rd St NW as a 2 story bay, then 2 second story bays, 2 non-bays, 2 bays w/ entryway porches, 2 non-bays with entryway porches, 2 bays with entryway porches, then 1551 with a two story bay.
