You can make a complaint about an unregistered 1-2 family home that is not occupied by the owner or the owners’ family with the Department of Housing Preservation and Development (HPD). Annual registration with HPD is required for a building with one or two units where neither the owner nor any family member occupies the building.
Maintenance complaints and building condition complaints can be made regardless of a building’s registration status.
HPD will research the complaint and advise the owner to register the building.
