The Melacha of Hotza'ah: Carrying Between Domains on Shabbos

The Torah's prohibition of hotza'ah includes taking an object from a private domain into a public domain, bringing it from a public domain into a private domain, and carrying it four amos within a public domain. The object need not be valuable, the distance need not feel long, and the act need not look like work. A key, siddur, tissue, bottle, stroller, or child's toy is enough to raise the question.

That is why the ordinary language of “carrying” can be misleading. Hotza'ah is defined by the object, the domains, and the way it moves. A person can cross a doorway and complete the melacha within a few steps. A person already outdoors can carry four amos without crossing any doorway at all.

The four domains of Shabbos

The Mishnah and Gemara divide places into four halachic domains: reshus hayachid, reshus harabim, karmelis, and makom petur. These are halachic classifications, not descriptions of ownership. A privately owned driveway can have the status of an outdoor public-type domain, while an area used by many people can sometimes be a reshus hayachid because it is properly enclosed.

Reshus hayachid

A reshus hayachid is the primary private domain for Hilchos Shabbos. The Alter Rebbe defines its basic form as an area at least four by four tefachim, enclosed by mechitzos ten tefachim high (Shulchan Aruch HaRav 345:1). A home is the familiar example, but ownership is not what creates the classification. The size and enclosure do.

Even a place that is a reshus hayachid min haTorah may remain restricted midivrei sofrim. When separate homes open into a shared courtyard, Chazal prohibited carrying between the homes and the shared area until the residents are joined through an eruv chatzeiros. The physical domain and the communal eruv are therefore two different parts of the halacha.

Reshus harabim

A reshus harabim is the public domain in which hotza'ah applies in its full Torah form. Chazal identify the great public road, the public square or marketplace, and passageways that are open through from one public way to another (Shabbos 6a). The later Poskim discuss width, public passage, whether the road is roofed, the form of the surrounding city, and the dispute concerning shishim ribo.

Those questions are central to a city eruv. If an area contains a reshus harabim de'oraisa, the kind of enclosure required can be very different from the arrangement used around a karmelis. The full subject is treated under Reshus Harabim in a Modern City.

Karmelis

A karmelis is neither a complete reshus hayachid nor a complete reshus harabim. Chazal prohibited carrying between a karmelis and either of those domains, and prohibited carrying four amos within a karmelis. The classification commonly applies to unenclosed outdoor areas that do not meet the conditions of a Torah-level public domain.

The practical prohibition remains real. Calling a street or open area a karmelis does not mean that an ordinary person may carry there. It means that the prohibition is Rabbinic rather than the complete Torah form of hotza'ah.

Makom petur

A makom petur is the fourth domain. It is generally a place too small or otherwise lacking the dimensions required for the other classifications. Its name, an “exempt place,” does not make it a general device for moving objects between domains.

Passing an object through a makom petur does not automatically interrupt hotza'ah. The Alter Rebbe rules that when an object moves from reshus hayachid to reshus harabim through a makom petur without coming to rest there, the intermediate place does not divide the act (Shulchan Aruch HaRav 346:1).

The Four Halachic Domains on Shabbos gives the measurements and distinctions in greater detail.

Transferring from one domain to another

The classic form of hotza'ah begins with an akirah, lifting or removing the object from its place in one domain, and ends with a hanachah, placing it down in the other. Taking a key from inside an apartment and walking out with it, carrying a siddur from a building to the sidewalk, or bringing food from the street into another building can all contain that basic movement.

The reverse act is called hachnasah, bringing in. Although the melacha is commonly called hotza'ah, the Torah prohibition includes both directions.

A doorway can contain several domains

The inside of a building, its entrance, front steps, vestibule, yard, sidewalk, and street do not necessarily share one status. A threshold can be a reshus hayachid, karmelis, makom petur, or part of the outside domain, depending on its construction and measurements. Apartment houses add shared halls, lobbies, stairways, and courtyards, which may carry their own Rabbinic restrictions even where the whole structure is enclosed.

This is why standing near the door or moving an object only a short distance does not settle the question. The relevant point is where the object began, where it came to rest, and what domains lie between them.

Handing an object to another person

Hotza'ah can be divided between two people. One person may perform the akirah and another the hanachah. That division can change whether either person has performed the complete Torah act, but it does not turn the transaction into an ordinary permitted way to move an object through the street. The Rabbinic prohibitions surrounding partial acts were enacted precisely to keep those acts from becoming a complete melacha.

The mechanics of the transfer are discussed in Transferring an Object From One Domain to Another.

Carrying four amos in reshus harabim

Hotza'ah also includes carrying an object four amos within a reshus harabim. No doorway or transfer between inside and outside is required. A person who finds an object in the street, receives something from another person outdoors, or removes an item from a stroller can create a separate carrying question while remaining in the same public domain.

Four amos is a halachic measurement, not an estimate of whether the walk felt brief. The detailed laws include the object's akirah and hanachah, the way the distance is measured, and the effect of stopping along the route. Deliberately dividing a journey into repeated short segments is not a normal permission to carry through the street.

Carrying Four Amos in a Public Domain treats this form of the melacha separately.

What a valid eruv changes

The word eruv is often used for the entire city arrangement, but several halachic elements are involved. A valid enclosure can establish the area within its boundary as a reshus hayachid. The communal eruv or shitufei mevo'os then joins the separate residences and shared areas in the manner required by Chazal. Where necessary, sechiras reshus must also be arranged.

Each part answers a different question. Bread used for an eruv chatzeiros does not repair a broken boundary. Poles and wire do not create the communal joining. Weekly inspection can confirm that an approved physical route remains intact, but it cannot decide the original classification of the streets or supply rabbinic approval that was never given.

A valid eruv also does not permit every object or every activity. Muktzeh remains muktzeh, and the other melachos and halachos of Shabbos remain in force. The eruv addresses carrying within the area that has actually been enclosed and joined.

How a Valid Eruv Changes the Practical Status of Carrying explains how these layers fit together. What Makes an Eruv Valid Under Halacha covers the city-wide requirements in full.

Carrying in Crown Heights

The Crown Heights Rabbonim have ruled that carrying in the neighborhood streets is prohibited and that the publicized eruv may not be relied upon. The ruling applies to the ordinary objects involved in Shabbos life: keys, siddurim, food, strollers, bags, clothing, and children's items.

The Practical Halachos of Carrying in Crown Heights address those cases directly. Preparing for Shabbos Without an Eruv gives the arrangements that are best made before candle lighting. Medical, safety, and mobility cases involve their own halachos and are treated separately under Medical and Mobility Needs on Shabbos.

The local psak itself, including the signed rulings and the Beis Din's published Tishrei guidance, appears under Rabbinic Rulings on Carrying in Crown Heights, 2015–2026.
