ADA and California compliant Unisex Restroom Door Sign Why is there no gender symbol/pictogram on this restroom door sign? California Division of the State Architect Bulletin 17-01: When changing identification symbols of existing single-user toilet facilities from gender-specific to all-gender, DSA advises against providing a pictogram to represent an all-gender image on a designation sign or unisex symbol. The pictogram might be perceived as inappropriate, and in fact, DSA reminds facility owners that a pictogram is not required.
