Code: UB (DOB violation label)
Description: (Unsafe Building) is the DOB term used for a building, structure, or part of a structure that is considered dangerous to public safety. It can be open, vacant, unguarded, or structurally compromised.
Practical Meaning: A UB condition means the property may need urgent action to protect people and prevent city enforcement. The owner may need repairs, securing, demolition, or court-related steps.
Where You May See It: You may see UB in BIS, DOB violation records, court-related unsafe building paperwork, or DOB unsafe building notices. It also appears in DOB guidance that explains how to search violations by borough, block, lot, or address.
Why It Matters: UB matters because it signals a serious safety problem and can lead to inspections, court action, repair orders, or city intervention. It affects safety, deadlines, and enforcement, and it can delay refinancing, sale, or normal property use.
