Grandpa Gohan's house (孫悟飯の家), also known as Goku's house (悟空の家), is located at the foot of a forest near Mount Paozu. There is the hut where Goku lived with Grandpa Gohan as a boy and, some time after the end of the 23rd World Martial Arts Tournament, the Ox-King had the large house built near the hut for Goku, Chi-Chi and their family to live together. Incidentally, the Ox-King is often seen spending time with the family here as well.
Goku's house features a kitchen in the white hut area, a bedroom with its window facing the old hut and presumably another bedroom in either the other side of the larger part or the narrow side area which connects to the larger part of the house. There is also an outdoor bathtub (which is effectively a steel barrel over the top of a fire) as seen during the first four Dragon Ball Z movies and the end of the Kid Buu Saga.
In Future Trunks' Alternate Timeline, the Goku's house is where Future Goku passed away from Heart Virus his bedside surrounded by his wife Future Chi-Chi, family, friends, and fellow Future Z-Fighters. Following the deaths of all the Z-Fighters save for Future Gohan, Future Ox-King moved in with his daughter Future Chi-Chi due to the threat of the Androids and Future Chi-Chi being all alone after Future Gohan effectively moved out in order to readily confront the Androids.
Oddly enough, during the time of the Dragon Ball GT television special A Hero's Legacy, which takes place long after the end of Dragon Ball GT, the old hut still remains reasonably intact. However, there is absolutely no sign at all that the house for Goku and his family was ever there though it is likely their family residences may have been moved in the intervening years while Grandpa Gohan's house was likely left behind as a sort of memorial.
- Grandpa Gohan – Owner of the hut. Deceased.
- Goku – Grew up in the hut as a child and technically inherited the hut after Grandpa Gohan's death which he lived in until his encounter with Bulma, but moved into the larger house built by Ox-King.
- Future Goku - In the Alternate Timeline, he lived in the larger house built by Future Ox-King with Future Gohan and Future Chi-Chi until his death via Heart Virus. Future Goku passed away in his home surround by his family, friends, and the future Z Fighters. As a boy he lived in the hut owned by his adoptive grandfather.
- Chi-Chi – After her marriage to Goku, she moved from her father's castle on Fire Mountain into the larger house built by her father.
- Gohan – Lived with Goku and Chi-Chi but later on moved into a house next door to Goku's house after marrying Videl.
- Future Gohan - Lived with his father and mother until his father's death by Heart Virus. Apparently moved out following the deaths of the Future Z Fighters in order to be able to readily confront the Androids and possibly to keep his overbearing mother Future Chi-Chi from interfering with his training as she had during his youth.
- Icarus – During certain movies and filler material, most notably the Garlic Jr. Saga and the filler episode "Goku's Ordeal".
- Goten – Grew up in the house that Chi-Chi, Gohan (until he moved next door) and Goku (after he came back to life) live in.
- Videl – Moved into a house next door to Goku's house after marrying Gohan. Before her marriage to Gohan, she occasionally stayed in Gohan's childhood home while hanging out and dating Gohan.
- Pan – Grew up in the house that Gohan and Videl lived in after they got married.
- Ox-King – Responsible for constructing the large house used by his daughter Chi-Chi, son-in-law Goku, and grandsons Gohan and Goten. Has only been seen sleeping in the house once, so it is unknown if he lives there, but he is seen there with Chi-Chi whenever she's there. It is likely that he resides their while visiting his daughter and her family.
- Bulma - Briefly visited the hut Goku inherited from his Grandpa Gohan. In Dragon Ball Z: Lord Slug, she briefly stayed the night with Chi-Chi and Gohan (before he left with Icarus) in the Son family home.
- Krillin - Occasionally stayed in the Son family home on several occasions while visiting Goku and Gohan. He briefly slept here along with the Ox-King during the Vegeta Saga Filler after he failed to inform Chi-Chi of Goku's death during the battle with Raditz and Gohan's abduction by Piccolo.
- Piccolo – During the Trunks Saga to readily train with Goku and Gohan, though apparently preferred to (or was force to by Chi-Chi) sleep (and meditate) outside.
- Yamcha - During the Androids Saga, he stayed their while Goku was bedridden via Heart Virus assisting Chi-Chi in caring for Goku and possibly to stand guard in the event they where attacked by the Androids.
