(Mishnah): A person may not open a bakery or dyer's shop underneath his neighbor's storeroom nor may he build his barn there.

They permitted opening it under a wine store but not a barn (as the heat is beneficial to the wine but not to the animals.)

A shop in a courtyard - a neighbor may protest it, saying, "I cannot sleep because of the noise of the people coming and going!''

Craftsman may produce vessels and sell them in the market and a neighbor may not protest, saying, "I cannot sleep because of the noise of the hammer or the millstone or the children.''

(Gemara): R. Yaakov bar Acha moved a baker from one neighborhood to another (to avoid baking underneath a neighbor's storeroom).

R. Yosi's brother, R. Avdumi, had a baker living underneath him. R. Acha passed by there and he did not object to the baker being there.

R. Avdumi to R. Acha: How could the Chachamim pass by and not protest this?

R. Acha became angry at R. Avdumi for saying this. R. Avdumi became sick and then deteriorated even more.

R. Avdumi's brother R. Yosi went to visit him (and saw that nobody was helping him, because R. Acha was angry with him).

R. Yosi to R. Avdumi: I will go and appease R. Acha.

R. Yosi went and told the Beis Din (with R. Acha at its head), that R. Avdumi was sick. (R. Acha and his) Beis Din took pity on him and told them to prepare burial shrouds.

A person once sold his whole courtyard with the houses. He withheld for himself a small attic and would regularly go and sit there.

The case came before R. Yona and R. Yosa. The buyer (who now lived in the courtyard and its houses) said that he cannot avoid the seller - since he regularly goes and sits in his attic, he can see all of the comings and goings in the buyer's home. (The Beis Din ruled in favor of the buyer that the seller can no longer continue to come and go freely).

A person once sold half of his courtyard and house and allowed a baker to remain there (in the other half).

The case came before R. Yona and R. Yosa. (The buyer wanted to evict the baker. They said to the buyer, "You came to the baker!'' (i.e. he preceded you), and we have learned (meaning that it can be deduced from out Mishnah) that if the cowshed or shop preceded the storeroom, the storeroom owner cannot object.

Based on our Mishnah, the Beraisa taught - They permitted opening a bakery under a wine store - even though the heat rising from the bakery reduces the wine, ultimately it improves it.

When Rav Hoshiyah heard this Beraisa, he left his wine on the roof of the bathhouse, thinking that it would improve the wine, but the wine, in fact, spoilt. He first thought that the Beraisa mislead him, but he later realized that he had misunderstood the Beraisa - although heat is good for wine, the smell of the bathhouse damages it.

Beraisa (Chachamim): If the cowshed owner wishes to rent it out to another person, the neighbor can say that he only agreed to the owner using it as a cowshed, but not anyone else. But once he agrees to allow the renter, he can no longer retract.

Rabban Shimon ben Gamliel: Even then he can retract, as he could say, "After you leave, the people who used to come to see you will continue to come and ask me where you are, so there are too many comings and goings in the courtyard''.

R. Chanina and R. Mana disagreed: One said that the case of the Beraisa where the owner wishes to rent it out to another person and if the neighbor agreed, he cannot retract, it is referring to bringing in a new tenant to a pre-existing cowshed or shop underneath him. However, for the tenant to then make a new cowshed or open a shop, the neighbor could still retract and object.

The other one: It is referring to opening a new shop - even then, if the neighbor agreed, he cannot retract.

Rabban Shimon (who says that he can retract even after agreeing) follows the view of R. Meir...

Mishnah in Maseches Kesuvos: About any blemish of the husband that she accepted coming into the marriage, R. Meir says that she can say, "I thought that I could bear it but I now realize that I cannot''.

The Mishnah taught: ...And a neighbor may not protest, saying, "I cannot sleep because of the noise of the hammer or the millstone or the children.''

The noise of children refers to the noise of their Torah learning, but he can protest the noise of their being taught signals to communicate with their friends.

The neighbor could (also) complain that the one who brings the children is increasing the comings and goings in the courtyard.

The people of Tzipori would protest when a resident of a courtyard would make a garbage dump in the courtyard, because of the heat that it produced.

R. Avimi bar Tuvi ruled that one person may make a dump between two walls.

R. Yitzchak bar Chakilah ruled that the place used for chopping cedar wood should be distanced four amos from the wall.

R. Yosi bei R. Bun: The reason that we see house walls becoming softer is because cedar wood is chopped nearby.

When the place where clothes are soaked with dog excrement for washing, is next to a wall, the wall becomes so weak that it can fall down just from the roar of the lion cubs in Persia. (Therefore, when soaking clothes in this way, they must be distanced from a wall to prevent damage.)
