Code: UB/UB*/UB% (DOB unsafe building label)
Description: (Unsafe Building Violation) is the DOB violation label used when part or all of a building is officially designated unsafe. UB* means the unsafe building violation was dismissed, and UB% means a precept was issued so the city can step in and do emergency work at the owner’s expense.
Practical Meaning: This usually means the owner must fix dangerous conditions quickly, often with help from licensed professionals, or face stronger enforcement. UB% signals that the situation is serious enough that the city may do emergency work and charge the owner.
Where You May See It: DOB violation notice, BIS, DOB NOW, OATH/ECB summons, title report, attorney due diligence review, managing agent or bank emails.
Why It Matters: Unsafe building violations can lead to strict deadlines, higher repair costs, and serious safety risks for tenants and neighbors. They may also block refinancing or sale until the violation is cleared and the building is back in a safe, legal condition.
