Poor door
A 'poor door' is a separate entrance in a housing development for those living in less expensive apartments. The term was coined by the local news site West Side Rag in August, 2013, where it was used to describe a new development on the Upper West Side of Manhattan that had separate entrances for market-rate and affordable-housing tenants.
