Venice, Italy and mold?

Why aren’t homes in Venice made unlivable by mold and mildew? With all that water constantly bathing the place, how do they keep it at bay?

They just cope like any other seaside town. I grew up in beach cities and more than one friend was forced to move inland because someone in the family had a severe reaction to mold. Of course, when I was kid, all those beach homes had shag carpeting like the rest of the country. Now, most have sensible tile flooring.

Many of the houses in Venice no longer use the first floor due to the frequent floods.
