DOB
DOB polices the building as a structure and everything built, altered or operated in it: construction work and permits, elevators, boilers, facades, cranes, zoning and illegal use. Its inspectors write violations against the Building Code and the local laws with ongoing compliance duties, and its summonses are decided at OATH.
A DOB violation stays open until the owner files a certificate of correction and the agency accepts it, which makes DOB records a paperwork trail as much as a repair trail: the condition may be long fixed while the record still says uncorrected. Open DOB violations block permits, certificates of occupancy and closings, which is the quiet pressure the record applies.
Every DOB violation carries a type code, and this site publishes the full catalogue as browsable reference pages with live counts.
