This run down house is the home of Denzel Crocker and his mother, Dolores-Day Crocker. Set around the house are a number of fairy traps, although according to Denzel they never work. Mr. Crocker sometimes also creates fairy tracking devices in his garage.
The house has been around since the 1970's and it is in very poor condition in the present day, with broken windows, peeling paint, a broken roof, creaky floors and cracked sidewalks being just one of the many poor qualities of the foundation. Back in the 1970's, the house was in much better condition than it was in the present. (see Dimmsdale (1972).)
Here Crocker spends most of his time updating his website (fairies'r'real.wand) and collecting any evidence related to Fairies' existence. He also has a built-in passage way that leads to The Crocker Cave. In "New Squid In Town!", when Crocker was temporarily captured by Mandie, his mother makes it vacant and turns it into a guest room until Crocker came back due to Mandie finding out that he was not Mark.
