SACRAMENTO, Calif. - San Francisco has the highest rate of substandard plumbing among California's 58 counties, an issue that is made even more pronounced during the coronavirus pandemic when washing hands is one of the most effective ways of warding off disease.
Nearly 2% of houses in San Francisco don't have adequate plumbing, more than four times that in Los Angeles, according to an analysis by the nonpartisan Public Policy Institute of California.
