Two family homes and townhouses: what applies to you

Many Mariners Harbor homes are two family houses. If you live in one unit and rent the other, you do not register with HPD. If you rent both units and live elsewhere, you must register every year by September 1.

Most of the posted notices on this page are for buildings with 3 or more apartments. Every home still needs working smoke and carbon monoxide alarms, and many owners add simple signs like no parking in the driveway or meter room labels.

Tips for Mariners Harbor owners and supers

  • Renting out a two family home and living elsewhere? Register with HPD every year by September 1.
  • A No Parking sign keeps a shared driveway clear for tenants. We make them to order.
  • Buildings with 3 or more apartments need the full core set, starting with the registration number sign.
