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.

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.
