What color is my line? - Accessible Parking

June 11, 2019

Question: A person is scheduled to restripe a parking lot. Is there a requirement for the painted lines to be the color blue?

Answer: The American’s with Disabilities Act (ADA) does not specify the color of the lines. While the ADA does not specify color, it is suggested that the paint color have a good contrast to the pavement. The access aisles must be marked to discourage parking in them. This is especially important because the standards allow a van access aisle to be as wide as a parking space. Additionally, the ADA does not require the ISA symbol to be painted on the ground, but does require that the ISA symbol to be provided on a sign that is 60” high measured minimum to the bottom of the sign from the ground. The ADA indicates that the ISA must contrast with the background of the sign either light on dark or dark on light. Some state or local governments may have additional regulations.
