What Is a Kosher Sukkah?
A kosher sukkah is not just any outdoor booth or shaded structure. It must meet specific halachic requirements involving its walls, size, height, schach, and location.
Whether you are setting up a sukkah in a backyard, driveway, porch, deck, or balcony, it is important to understand the basic rules before building.
When should a sukkah be built?
A sukkah may be built before Sukkos, even well before the holiday, as long as it is built for the mitzvah of sukkah.
Many people try to begin building the sukkah after Yom Kippur, going from one mitzvah to the next. However, a sukkah can also be built during the days before Sukkos, and in some cases during Chol Hamoed. It should not be built on Yom Tov or Shabbos.
If a sukkah was left standing from a previous year, or was originally built for shade and not specifically for the mitzvah, there may be a need to “renew” something in the sukkah, often by adding or adjusting part of the schach. For a practical ruling, ask your rabbi.
What size does a sukkah need to be?
A sukkah must be large enough for a person to sit in it properly. The minimum size is commonly discussed as 7 by 7 tefachim. In practical measurements, this is approximately 56×56 cm according to the more lenient opinion and around 70×70 cm according to the stricter opinion.
There is no real maximum length or width for a sukkah. A sukkah may be small and simple, or large enough for a family meal, guests, or a community gathering.
How tall does a sukkah need to be?
The walls of a sukkah must reach at least ten tefachim. This is commonly measured as about 80 cm according to the lenient opinion and about 1 meter according to the stricter opinion.
A sukkah also cannot be too tall. If the schach is too high above the floor, the sukkah may not be valid.
Where can a sukkah be built?
A sukkah must be built under open sky. It should not be built under a roof, tree, balcony, pergola, or anything else that blocks the schach from being directly under the sky.
This is one of the most important things to check before setting up your sukkah. Even if the frame, walls, and schach are perfect, the location can affect whether the sukkah is kosher.
What makes schach kosher?
Schach must come from something that grew from the ground and is no longer attached to the ground. It also must be placed in a way that provides shade while still allowing the sukkah to remain a sukkah, not a sealed roof.

Why the right sukkah matters
A good sukkah should be practical, sturdy, and easy to set up. But it also needs to be built with the halachic requirements in mind.
