Hello we are adding a second floor to a house and want to make a flat roof and put the succah on the roof. What is the maximum height for where the succah may be lmasseh, and is that measurement for the bottom of the succah or top of the succah?
The succah has to be no more than 20 amos from the floor of the sukkah until the schach. Which is 9.6 meters or 31.5 feet tall according to R’ Chaim Naeh. This is way more than the height of most people’s succah.
Succah 2a, O:CH 633-1, M:B 633-1.
