Every building I went into (I did not go into any homes) had a warning sign that the building contained substances "known to the State of California to cause cancer". What's up with that? Lotta cancer out there?

That was the result of Prop 65, the "Clean Water Act," IIRC.

Proposition 65, the Safe Drinking Water and Toxic Enforcement Act of 1986, was enacted as a ballot initiative in November 1986. The Proposition was intended by its authors to protect California citizens and the State’s drinking water sources from chemicals known to cause cancer, birth defects or other reproductive harm, and to inform citizens about exposures to such chemicals.
