Don’t call it a men’s room. Or a women’s room. The era of the “all gender” restroom begins this spring, at least for public, single-user facilities.   Beginning March 1, 2017, if you have a single-user bathroom facility in your leasing office or other public area, it must be identified with signage as an “all gender” facility. The signage must comply with Title 24 regulations. Moreover, the bathroom must be designated for use by no more than one occupant at a time or for family or assisted use.
