How to Mount Your ADA Signage

Please follow the architectural plans and any callouts for any project you may be working on. What contains here are what’s acceptable by the authorities and our recommendations.

By the California ADA compliance codes, the bottom tactile lettering cannot be lower than 48” and cannot be any higher than 60” from the bottom of the top tactile. (Please see diagram) If there are no call-outs, we recommend the sign to be mounted at 54” from the bottom of the sign to the floor. This is normally a good height that is central and most importantly compliant.
The wall signs, including Room ID’s and bathroom signs should be mounted on the same side as the door handle. If the space is too small, mount it on the wall closest to the handle.
You can follow the same guidelines for the door signs as well. For bathroom signs, we typically see them measured 60” from the center of the sign to the floor. This would again, put the bottom of the sign at 54”, since the door signs are uniformly a circle for the female bathroom, triangle for male and both for unisex bathrooms 12” in height and 12” in width.
Yes. The sign should be a contrasting color to the wall it’s being mounted on, ie: if the walls are white, the substrate of the signs should be black, blue or any darker color. Vice versa if the walls are dark. The substrate should be a lighter color.
Room ID is required for rooms that do not change, like restrooms, kitchens, maintenance rooms, etc. Office room numbers, multi-use rooms may have several functions or can change over time. Those are not necessary to have Room ID signage, but it doesn’t hurt to have, especially aesthetically. Plus we can always replace them.

All ADA braille has to be grade II. The dome shape is what makes it grade II braille. The size of the braille dots is the same in both California and federal guidelines, but the spacing of the California braille is more spaced out.
