In the last Washington Sanitary Improvement Company (WSIC) post I searched the DC Recorder of Deeds for any other properties in Truxton Circle they may have owned besides the ones on Squares 552 and 615. I discovered Sq. 617.
On Square 617, they owned lots 169 to 183.
So that would be 14-42 O St NW.
This is 14 O St NW. Note the difference in lot number. It was lot 183 100 years ago.
This is 42 O St NW.
I’m noticing a particular building style here, but it looks irritating.
