The mansion remained a condemned building (According to Morticia, it had actually been condemned five times), and the interior had various dangerous objects and odd statues just like the original TV show. The New Addams Family provided a cross between the original TV show's mansion and the movie/comic strip's mansion.

In the 2019 adaptation, the mansion is a former mental asylum located on a hill in the outskirts of New Jersey which also houses a disembodied resident who wants the place to remain undisturbed. The movie The Addams Family had the mansion appearing as it did in Charles Addams' drawing of the family about to dump boiling oil on a group of carolers from the roof, a gag reenacted in that film. The two Addams Family movies, 1991's The Addams Family and 1993's Addams Family Values, along with the 1990s animated series, resurrected the mansion's original exterior design from the Charles Addams cartoons. In the Halloween special, an entirely different mansion is shown. In the following series, the Addamses bought a recreational vehicle which resembled their mansion and drove it around the country.

The house once again became a condemned mansion in the New Scooby-Doo Movies TV show, in which the Addams made a guest appearance.

The house also sported a Play Room with medieval racks, nailbeds, iron maidens, and stockades for 'relaxing.' Instead of being a dilapidated house, it was now practically a museum filled with odd statues, trophies, and other interesting things. In the original series, the house was given the address 0001 Cemetery Lane.
