Add housing by allowing one triplex per city block

The addition of one triplex per block would have negligible neighborhood impact and help meet Seattle Mayor Ed Murray’s goal of 50,000 new housing units.

I’M a literal kind of guy, so I was struck by something Seattle City Council District 5 candidate-elect Debora Juarez said: “While I support increasing the diversity of the housing stock in these zones by encouraging mother-in-law apartments and backyard cottages, I don’t think that building triplexes on every block is going to significantly alleviate our housing affordability crisis.”
I was interested in the image of “triplexes on every block” and wondered if, literally, one triplex on every block would be significant.
So I thought, “OK, let’s do the math.”
According to the City of Seattle, there are 15,740 blocks in single-family zones. (The city defines one block as having two “block faces.”) That would mean 15,740 lots on which to build a triplex.
