(SAN RAFAEL, Calif.) -- The town of San Rafael, Calif., has passed a ban on smoking that city officials have called the most stringent in the nation. The new ordinance makes it illegal for residents to smoke in their own homes if they share a wall with another dwelling.
The ban applies to owners and renters alike, and it covers condominiums, co-ops, apartments and any multi-family residence containing three or more units.
Rebecca Woodbury, an analyst at the San Rafael City Manager's office, helped craft the ban, which took effect Nov. 14.
"We based it on a county ordinance," she told ABC News, "but we modified it, and ended up making it the strictest. I'm not aware of any ordinance that's stronger."
Cities with similar but less severe smoking restrictions include Cambridge, Mass., and other California cities, including Walnut Creek and Tiburon. In June, the Related Companies became the first developer and property owner to ban smoking in all 40,000 of its rental residences in 17 states.
Jessica Scaperotti, a spokeswoman for Related, said the ban had been popular. "There are more people who want to live in smoke-free environments than there are apartments available. Demand far exceeds supply."
The provisions that make San Rafael's rule unique, said Woodbury, include the prohibition on smoking in dwellings that share a wall, including owner-occupied condos, duplexes and multi-family units. "It doesn't matter if it's owner-occupied or renter-occupied. We didn't want to discriminate. The distinguishing feature is the shared wall."
As justification for the rule, she cited studies showing that secondhand smoke seeped through ventilating ducts and walls, even through cracks. "It depends on a building's construction," she said, "but it does affect the unit next door, with the negative health impacts due to smoke."
The ordinance cites such studies, plus a 2011 study by UCLA that found that California property owners paid up to $18 million a year to clean apartments vacated by tenants who'd smoked.
Asked if there was opposition to the ordinance, Woodbury said there was hardly any. "We have a very low percentage of smokers in the county," she said, referring to Marin.
George Koodray, New Jersey state coordinator for Citizens Freedom Alliance and the Smoker's Club, called San Rafael's rule and ones like it "mischievous."
