The Housing Maintenance Code is about living in a building — heat, hot water, pests, paint — and is a different thing from the Department of Buildings violations elsewhere on this page, which are about building work. The two most common open violations in the whole city are both paperwork, so a high count is a reason to read the classes rather than a verdict. What each class means Counted from the extract accessed Sep 18, 2026.

How to read this street page

A shared street name does not mean a shared project.

These records are grouped by the street name and borough published by DOB. Each address remains an independent filing unless its source record explicitly connects it to another site. Use this page to scan activity along the corridor, then open an individual filing for its exact status, scope and identifiers.

The whole street

A block of West 123 Street, as it stands.

Each building is its own outline at its own roof height, in its own place — the gap down the middle is the street. Turn it to see the other side. The letter on a roof is the building class the city files it under.

22 of the 164 lots the city maps on West 123 Street — about 310 feet of it, the tallest 25 metres. Each building is the outline City Planning publishes for it, raised to the roof height the city measured, and placed where it stands in relation to its neighbours; nothing is arranged and nothing is to a different scale from anything else. The gap down the middle is the street. A letter is the building class the city files that building under.

Building by building

What stands on West 123 Street, and what is being done to it.

A filing is about a building rather than about a street, so the records here are grouped into the buildings they name. Each drawing is that building’s own footprint at its own roof height, from the outlines City Planning publishes; the panel beside it is what the tax roll records about the lot, and the last one is every filing here that names it.

164 lots are mapped on West 123 Street. These are the first 6, and none of them is named by a filing.
