The UBC & California State regulations require that many areas on private property such as curb ramps and cut-outs, wheelchair ramps, accessible routes, entrances, and paths of travel feature yellow truncated domes to serve as a detectable warning to pedestrians.
Federal & State ADA laws require that truncated domes are installed in specified areas to alert blind, partially sighted, and other pedestrians that they are transitioning from a pedestrian area to a space shared with vehicles. An example would be leaving the sidewalk to enter the street or a parking lot. They provide a yellow, tactile warning system in a distinct pattern that can be detected by a cane or felt underfoot.

Truncated domes must be yellow & have a base diameter of between 23mm & 36mm. Regulations also state that the top diameter is between 50-65% of the base diameter. Keep an appropriate base to base spacing of 17mm between domes.
Where truncated domes are installed at platform boarding edges they must be 610mm wide and extend the entire length of the public area of the platform.
For additional ADA construction work, our parent company Protrk Construction is a dedicated ADA contractor serving San Francisco and the Bay Area.
The ADA states truncated domes must be yellow & have a minimum base diameter of 23mm & shall not exceed 36mm. The top diameter of the dome shall be a minimum of 50% of the base diameter, and shall not exceed 65%.
I'm working with Mike Schaeffer with Protrk to comply with the 2019 San Francisco Mandatory ADA Access ordinance on two commercial properties I manage. Mike is responsive, knowledgeable, thorough, easy to work with, and welcomes feedback from his clients. I highly recommend his services.
