The number of required accessible spaces depends on your total lot size. For lots with 1-25 total spaces, you need 1 accessible space. 26-50 spaces require 2, 51-75 require 3, 76-100 require 4, and 101-150 require 5. For lots over 500 spaces, you need 2% of total. At least 1 in every 6 accessible spaces must be van-accessible.
What are the fines for ADA parking lot violations?
ADA parking violations can result in fines up to $75,000 for a first offense and $150,000 for subsequent violations under federal law. Additionally, property owners may face lawsuits, legal fees, and mandatory remediation costs. Many states impose additional penalties.
What is the required width of an ADA parking space?
Standard accessible parking spaces must be at least 8 feet wide with a 5-foot access aisle. Van-accessible spaces must be at least 8 feet wide with an 8-foot access aisle, or 11 feet wide with a 5-foot access aisle. The total combined width of space plus aisle should be at least 13 feet for standard and 16 feet for van-accessible.
What signage is required for ADA parking spaces?
Each accessible space must have a sign displaying the International Symbol of Accessibility (ISA) mounted at a minimum height of 60 inches so it remains visible when a vehicle is parked. Van-accessible spaces require an additional sign reading 'Van Accessible.' Signs must include the penalty for illegal use in many jurisdictions.
What slope is allowed in ADA parking spaces?
Accessible parking spaces and their access aisles must have a maximum slope of 2% (1:50 ratio) in all directions. This applies to both the running slope and cross slope. In Colorado mountain communities, achieving proper drainage while meeting slope requirements often requires professional grading.
