Factual Breakdown:
The Coal Connection: In the 19th and early 20th centuries, every building in NYC was heated by coal. Because coal was incredibly dirty, carrying it through a front door would coat the entire home in black soot.
Logistical Solution: Sidewalk "cellar doors" were engineered to allow delivery workers to slide heavy lumps of coal directly from the street into storage bins located next to the basement furnace.
Structural Risks: By law, these doors must support the weight of pedestrians. However, many are poorly maintained, leading to rust and warping that can cause them to collapse under a person's weight.
Obsolescence: The shift to oil and natural gas heating made these hatches largely unnecessary for residential buildings by the mid-20th century.
Current Usage: Today, these doors are primarily utilized by restaurants and bodegas for receiving large inventory and food shipments without obstructing the main entrance.
The "Burying" Trend: To avoid liability for maintenance or accidents, many modern building owners are filling the voids with dirt and cementing over the openings entirely.
