I notice that in Brownstones the FDNY calls the floor at the top of the front steps the parlor floor. I understand this is done to clear up confusion between the floor level below the front steps. It seems many parts of NYC have Brownstones, but I only hear them call it the parlor floor in Brooklyn. Is the term used throughout the job? Do I just notice it more because Brooklyn tends to have more Brownstones in high fire activity neighborhoods?
