If somebody sold a house, he only sold the house. He didn't sell with it the shed that may be attached to the house, even if the shed opens up into the house. Let's say the shed has an entranceway, and you can go directly into the house. What we say over here is that the shed is considered to be a totally separate structure. When a house is sold, if it's just listed as the house, the shed is not sold with it.
If a person has a storage room in his house, like a pantry where he just stores things, and it's not the usual type of room in the house, we say that the storage room as well is not included in the sale of the house. Even though it's inside the house, since it's used for a different function, it's not sold together with the house. Everything we're mentioning here would have to be listed separately in the contract. That's the point over here. If you're buying a house, you have to list the yatzia, which is the shed, as well. The storage room—everything has to be clear in the document.
A person also, if he sells his house, does not automatically include the right to use the rooftop to dry fruit or produce. If there was a fence, if there was an area of at least 10 tefachim (handbreadths), if there was a fence—which is a halakhic obligation on a de'oraita (biblical) level to make sure that the roof is safe—if there's a 10 tefach fence surrounding it, then it shows that the fence in rooftop was a separate entity. It was used by the previous owner of the house, and he didn't automatically include it in the sale. He may have rented it to other people. It was considered to be a reshut bifnei atzmo, its own domain. And the owner was having... He used it, so therefore it's not automatic that he included it in the sale.
Rabbi Yehuda goes even further. He says that if there's a doorway that leads from the house to the roof, even if the roof doesn't have a 10 tefach fence around it, then the right to use the roof is not sold along with the house, according to Rabbi Yehuda. That doorway is indicative that the roof has its own size. It's a significant jurisdiction that is considered to be its own area, and therefore is not included in the sale of the house.
