Arukh HaShulchan, Orach Chaim 310:7-12

Sugya Map

• Issue: Defining Hotza’ah (carrying) in a private domain versus a public thoroughfare. Specifically, the definition of Reshut HaYachid vs. Karmelit.
• Nafka Mina: Whether a roof or a balcony requires a mechitzah (partition) to attain the status of Reshut HaYachid.
• Primary Sources: Shabbat 7b, Shabbat 92a, Arukh HaShulchan, Orach Chaim 310:7-12.

Text Snapshot

"כל גג שהוא גבוה מן הארץ עשרה טפחים... הוה ליה רשות היחיד" (Arukh HaShulchan, Orach Chaim 310:7). Leshon nuance: The Arukh HaShulchan emphasizes the height (10 tefachim) as the defining spatial boundary rather than the structural ceiling, aligning with the logic of Shabbat 7b regarding makom petur.

Readings

• Rashi (Shabbat 7b, s.v. Gag): Posits that a roof is inherently Reshut HaYachid because it is elevated, separating it from the Reshut HaRabbim below.
• Arukh HaShulchan (310:10): Adds a chiddush: if the roof is used for walking, it retains its status even without walls, provided it isn't a thoroughfare. He distinguishes between the nature of the space and the containment of the space.

Friction

• Kushya: If Reshut HaYachid requires mechitzot (walls) per Shabbat 6a, how can an open roof qualify?
• Terutz: The roof is a makom (place) defined by its elevation relative to the ground. The elevation functions as a "virtual wall." As the Arukh HaShulchan notes, the diur (living) use supersedes the need for actual partitions.

Intertext

• Shulchan Arukh, Orach Chaim 345:1: Discusses the nuances of Karmelit vs. Reshut HaYachid.
• Mishnah Shabbat 1:1: The baseline definition of Reshut HaYachid as four by four tefachim.

Psak/Practice

The Arukh HaShulchan’s analysis suggests that modern balconies (if walled) or rooftop terraces are definitively Reshut HaYachid for Hotza'ah, provided they are not utilized as a public walkway.

Takeaway

Halachic space is defined by functionality and elevation as much as by physical masonry; if it serves as a private deck, the "view" from the street doesn't degrade its status.
