Some people keep their sliding doors and windows
(with considerable areas, especially here in Southern California)
opened most of the time. Should we then consider the houses partially
enclosed structures too?
IMHO, it all boils down to the same old question
- "Where are the bodies?" I never heard of the garage walls blowing our
due to the wind.

Since it is not code
mandated, the city should not decide. Ideally, the engineer of record
would discuss this with the Owner, but the engineer may simply set their own
criteria in absence of direction from the Owner.

In a message dated 2/17/2008 11:26:40 A.M. Pacific Standard Time,
recently asked a similar question on the listserver
regarding industrial buildings that have several large overhead doors along
one wall. It does not appear that the codes clearly address the issue
of open vs closed overhead doors/ garage doors.
appears that this is left to the engineer's judgment and/or the project
criteria. The written design criteria for some projects define a
primary wind speed for consideration as an "enclosed structure" and a
reduced wind speed for consideration as a "partially enclosed
structure" (e.g., 90 mph for enclosed and 60 mph for partially
enclosed). This assumes that the door can be open for some wind
pressures but is likely to be closed during extreme wind events.
