space periphery needs to be
open.
1. Add lengths of the outside
living space.
16'+20'+16'+20'=72'
2. Divide the open area length
by the total outdoor living
space.
20/72=.28
.28 is less than the .30 required
and therefore this installation
would not be approved.

.31 is greater than the .30
required and therefore this
installation would be approved.
