Covered and enclosed parking areas (garages) create protection from sun, wind, rain, and snow. Loading and unloading items under a covered structure is easier and more comfortable whether or not a health condition is present. Garages that can be closed and secured provide extra safety as well.
Exception:
If a garage isn’t practical due to finances or other reasons, a carport or other covered parking area is just about as functional, though the security that a fully-enclosed space offers won’t be available.
