I was interested by this but couldn't find anything about single piece doors being illegal. Being from California I've lived in a few places where these types of doors are common.

Sorry, I phrased that poorly.

There are many states where the typical California tilt-up single-piece door with levered extension springs does not meet code.

Apparently they are not secure in very high winds, so they're especially dangerous in hurricane/tornado country.

Ahhh that makes perfect sense. Thanks for the explanation.
