Hi, Airfall! My name is Sumit and I’m a mapper in the OSM team at Lyft. Thanks for bringing this to my attention. You are absolutely right. While making edits I relied on the Nearmap background that is the freshest but unfortunately the building wasn’t visible. I checked Lyft owned street view images and found that the building actually exists

I fixed this inaccuracy in the changeset-

My apologies. I will be more attentive when pushing change sets up.
Best regards, Sumit!
