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 Oct 1, 2026.
