That reminds me of the SROs that used to dot the SOMA area before being slowly replaced with high rises. Many of the warehouses in the area are being converted into offices. One room with shared bathrooms and kitchens. Chinatown still has some of this housing as does the Tenderloin. I believe the Tenderloin is losing it fast with all the tech companies moving to the mid Market area. I don't think it's a good long term housing situation because of the tragedy of the commons.
