Both HPD and DOB may inspect for illegal occupancy of basements or cellars. Each agency may issue violations for illegal occupancy conditions or issue Vacate Orders that the occupant leave the illegal space. If a Vacate Order is issued by either agency, the occupant is advised that they can receive relocation services through HPD. Property owners will be liened any costs incurred by the agency and provide relocation services (which may include temporary housing) to any occupants who receive these services. These costs can be significant.
