Signs designating accessible parking spaces must include the international symbol of accessibility and be placed at the front of the parking space to comply with the Americans with Disabilities Act, according to ADA National Network. Parking spaces for vans have additional requirements, and some spaces in smaller venues are excepted from the requirements for signs.
The Americans with Disabilities Act requires that signs for accessible parking spaces be 5 feet from the ground to the bottom of the sign, states ADA National Network. Signs for van-accessible spaces have to include the phrase "van-accessible." A 2010 update to the law requires that one-sixth of all accessible parking spaces be van-accessible. While new construction projects have to adhere to 2010 regulations, existing facilities that originally met the prior standard do not have to immediately updated.
Van-accessible spaces and their accompanying access aisles must total 16 feet in width. Standard van-accessible spaces are 11 feet in width with 5-foot access aisles, although the space and aisle may each be 8 feet in width, according to ADA National Network. Some parking facilities do not have to post signs for their accessible spaces. In parking lots with four or fewer parking spaces, accessible spaces do not have to be marked with signs, and residences with assigned parking spaces are exempt from the signage requirements for accessible spaces.
