The Washington Sanitary Improvement Company (WSIC), owned, on Square 552, according to the 1933-1934 General Assessment WSIC owned lots 33-35, 49-94, 98-100, 104-150, 811, and 816-820. Previous posts looked at the 100 block of Bates. Square 552 holds both the 100 and 200 block of Bates St NW.
Most if not all of the WSIC properties were built with two flats, as they were intended to be rental properties, not homes for homeowners. Looking at many of the houses on even side of the 200 block of Bates, there is only one property that had two entrances still in 2004.
A peek at Google street view and 222 Bates St NW, which only had one entrance in 2004. It seems sometime around 2015, 222 Bates St became two condos, with two separate entrances. And it got a pop-up.
So what’s the bay, no bay pattern? Starting with 200 Bates: 2nd floor bay, no bay, bay, bay, bay, no bay, bay, no bay, bay, no bay, bay, no bay, bay, no bay, bay, and bay. The pattern makes no sense.
Another thing should note about all the Bates Street houses, from the unit block on Sq. 615 to the 200 on Sq. 552, is there is no yard. It very much like a lot of Baltimore row houses. One steps out their door and the sidewalk is right there. No need for a lawnmower.
