Co-ops, condos and brownstones follow the same rules

Co-op and condo buildings with 3 or more apartments are multiple dwellings too, so the same HPD notices apply as in a rental. Boards often choose brushed aluminum or acrylic so the required notices match the lobby directory and mailboxes.

Much of the neighborhood is in the Park Slope Historic District. Landmark rules cover the outside of buildings, so check with the Landmarks Preservation Commission before adding signs to a facade. Indoor notices like the ones on this page are not affected.

Tips for Park Slope owners and supers

  • Matching sets look best in a renovated lobby. We can make every notice in one finish.
  • Brownstones with 3 or more apartments need a registration number sign in the entrance hall.
  • Owner occupied two family homes do not register with HPD. Two family homes where the owner lives elsewhere do.
