A new state law banning gender signs on single-use toilets went into effect on March 1, and the county parks department is reviewing its toilets while business owners are largely unaware of the law. The law requires all single-use toilets—defined as a bathroom with no more than one toilet and one urinal with a locking mechanism controlled by the user—in any business, public place or state and local government agency to now be identified by signage as all-gender facilities. The parks department, which oversees various public single-use toilets, including the public restrooms at Toby’s Playground in Point Reyes Station, two of which are gender-labeled, said most of its stalls are already compliant. “There may be one or two situations where … they’re not appropriately signed,” Steve Petterle, principal landscape architect for the parks department, said. “We’re double-checking to see if that’s the case. If so, we’ll be making the necessary changes soon.” An inspector can now scrutinize a business for lack of compliance. Cristy Stanley, the county’s supervising code compliance specialist, said the department is complaint-based and there have been no complaints made since the law went into effect. “At this point, the only action would be educating the business owner on the new law and making sure the right sign is in the right place,” she said. Many restaurant owners and managers across West Marin were unaware of the law’s existence. Sam Temer, owner of the Sand Dollar in Stinson Beach, said this was the first he had heard of the law and that he will look into updating the signs for his restaurant’s facilities. In San Geronimo, at the Two Bird Café, waitress Karina Halseth said the owner would comply with the law, but she had her own reservations. “Women in a bathroom are different than men in a bathroom,” she said. “Hygiene wise. Just flush the toilet and put the seat down.” Leslie Scott, an Inverness resident who published her memoir “Outside In, Inside Out: A Transgender Journey” last year, said the new law was “one step toward sanity.” “One of the primary motivations for transitioning from male to female is not to share bathrooms with men anymore,” she said.
