If we use the TV series as a source of inspiration, the Addams residence could be somewhere in the suburbs of Washington DC. There was an episode where a visiting Soviet dignitary randomly picked the Addamses from a local phone book as a "typical American family" to visit. So they could be either near the UN and NYC, or near Washington DC. (However, there are also embassies/consulates in Seattle, San Francisco and Houston that they could be near.)
