What Cities in the U.S.A. have the worse reoccurring mold, mildew and fungus growing on the exterior of homes.

Question

A great example of exterior mold, mildew and fungus growing out of control is in the City of Fort Lauderdale Florida. South Florida has some of the worse mold, mildew and fungus conditions in the entire country due to its climate; I would classify this area as an eight on a scale of one to ten and ten being worse.
