On March 1st, 2017 the new law requiring single occupancy bathrooms in California to be accessible to all genders went into effect. The bill (AB 1732) was signed into law on September 29th, 2016, but did not take effect for 5 months. Under the new statute, any bathroom in a place of public accommodation that is designed to be used by one person, must be designated as “unisex.” The state has defined a single occupancy bathroom as “a toilet facility with no more than one water closet and one urinal with a locking mechanism controlled by the user.” This new law does not require any new construction or structural changes, only a change in signage. The only explicitly stated requirement for the signage, is it must feature the unisex symbol, an equilateral triangle superimposed onto a circle.
