Sukkah Building Rules Explained: Who Can Build It and What Counts as Schach

A simple guide to shade, roofing, and the people who put the Sukkah together

Every year it happens the same way.

The panels go up. Someone drags out the bamboo mats. Fairy lights appear out of storage boxes that haven’t been opened since last Sukkot.

And inevitably, someone asks a question that sounds simple but isn’t.

“Wait… who actually built this Sukkah?”

Followed immediately by:

“Does it matter?”

And once the halachic gears start turning, the questions keep coming.

Could a non-Jew build the whole thing?
Is there a requirement that a Jew put on the Schach?
And theoretically – could someone just throw paper on top and call it roofing?

Sukkot has a way of turning otherwise relaxed holiday planners into amateur halachic investigators. And honestly, that’s part of the fun.

Behind the decorations and paper chains lies a festival full of precise rules, fascinating debates, and a surprisingly flexible approach to construction.

Let’s unpack two questions that come up almost every year: who can build a Sukkah, and what materials can actually serve as Schach.

Does a Jew Need to Build the Sukkah?

In many synagogues, apartment complexes, and community courtyards, the Sukkah doesn’t magically assemble itself.

Often a maintenance worker, caretaker, or contractor builds it from start to finish – walls, frame, and roof included.

This sometimes makes people pause.

Is that allowed?

Isn’t there a requirement that a Jew must build at least part of the Sukkah?

The answer, according to halacha, is straightforward:

A Sukkah built entirely by a non-Jew can still be perfectly valid.

What the Talmud Says

The Talmud directly addresses this scenario.

In Sukkah 8b, the Gemara states that a Sukkah built by non-Jews is valid provided it was constructed for the purpose of shade (לצל – l’tzel).

This ruling is codified in Shulchan Aruch, Orach Chaim 635, the standard halachic code governing the laws of Sukkot.

Why is the intention for shade so important?

Because that’s the very definition of a Sukkah.

The word itself refers to a shelter designed to provide shade. If the structure doesn’t function as shade from the sun, it’s not really a Sukkah at all.

Even according to the opinion that a Sukkah doesn’t need to be built specifically for the holiday (a view associated with Beit Hillel in Sukkah 9a), it must still serve as a legitimate shaded shelter.

So if someone – Jewish or not – builds a hut for shade using valid roofing materials, halacha considers it a kosher Sukkah.

But Isn’t Building the Sukkah a Mitzvah?

Here’s where many people are surprised.

The Torah’s commandment for Sukkot is not to build a Sukkah.

The mitzvah is to dwell in it.

For seven days, a person is meant to eat, relax, and ideally even sleep in the Sukkah.

Construction itself is not the biblical obligation – it’s simply preparation for fulfilling the mitzvah.

That’s why someone can fully perform the mitzvah of Sukkot even if they didn’t build the structure at all.

Even a Sukkah built entirely by a non-Jew can still be used for the mitzvah (Shulchan Aruch OC 635).

The “Ideal vs. Acceptable” Distinction

Later halachic authorities introduce a familiar distinction:

B’dieved (בדיעבד) – acceptable after the fact
L’chatchila (לכתחילה) – the preferred way to do things

Some rabbis suggest that ideally a Jew should participate in the building process, especially when placing the Schach.

Why?

Not because the Sukkah would otherwise be invalid, but because actively preparing for a mitzvah has its own spiritual value.

Fortunately, halacha offers a very easy solution.

A person can simply lift a piece of Schach and place it back down with the intention that it is for the mitzvah of Sukkah.

The Mishnah Berurah (635:1) explains that even this small action symbolically connects the builder to the mitzvah.

That said, many authorities emphasize that this step is not strictly necessary, particularly when the non-Jew was hired to build the Sukkah.

According to halachic principles, hired labor often functions as an extension of the employer’s actions (see Machaneh Ephraim, Hilchot Shluchin §11).

In other words:

If you paid someone to build your Sukkah, you’re still halachically involved.

What About the Shehecheyanu Blessing?

Another common misconception relates to the Shehecheyanu blessing.

Since this blessing is recited on the first night of Sukkot, some assume it must be connected to building the Sukkah.

It isn’t.

The blessing thanks God for allowing us to reach the festival and perform its mitzvot.

It relates to the holiday itself, not the act of construction.

So if someone else built your Sukkah – no problem. You haven’t missed anything.

Can Paper Be Used as Schach?

Now for the second question that pops up every year.

If Schach must come from things that grow from the ground, paper seems like it might qualify.

After all, paper comes from trees.

Trees grow from the ground.

So could paper technically be used as roofing?

Nice theory.

But halacha says no.

Why Natural Materials Matter

One of the central rules of Schach is that it must come from materials that grow from the ground and remain relatively natural.

This principle is outlined in Shulchan Aruch, Orach Chaim 629:4–5, with further discussion by the Magen Avraham.

The more a material is processed and transformed, the less suitable it becomes.

For example:

• Palm branches – ideal
  
  

• Bamboo poles – widely used
  
  

• Wooden slats – generally acceptable
  
  

But paper has undergone an intense transformation process.

The wood fibers are pulped, chemically treated, pressed, flattened, and dried until the final product bears little resemblance to its natural origin.

At that point, halacha considers it too processed to serve as Schach.

But Doesn’t Schach Just Need to Avoid Tum’ah?

Some people point out another rule.

Schach must not be susceptible to ritual impurity (tum’ah).

Paper is not a vessel and has no container function, so it technically doesn’t receive impurity.

That part is true.

But the rule isn’t the only requirement.

Schach must satisfy all criteria simultaneously – including being a natural plant material that hasn’t been significantly altered.

Because of this, items like paper, cotton wool, and flax rope are generally ruled invalid for Schach (see Shulchan Aruch OC 629 and Magen Avraham).

There’s Also the Practical Problem

Even setting halacha aside for a moment, paper has another issue.

Actually several.

Wind.

Rain.

And basic physics.

A paper roof would probably survive about five minutes outdoors.

Possibly less if there’s a breeze.

So even if someone tried to build a Sukkah that way, it wouldn’t last very long

The Big Picture of Sukkah Construction

Sukkot comes with a detailed set of rules – measurements, materials, and structural requirements.

But at the same time, the system has a surprising amount of flexibility.

A Sukkah built by a non-Jew?
Still valid.

A Sukkah assembled months earlier as a shade structure?
Also valid.

Schach made from simple natural branches or bamboo?
Exactly what halacha wants.

In the end, the goal isn’t perfect construction.

The goal is living inside the Sukkah.

Eating meals there. Spending time with family and friends. Looking up through the Schach and remembering the deeper meaning of the holiday.

And if someone else handled the construction?

That just leaves more time to enjoy the Sukkah itself.
