An increasingly large percentage of the population qualifies as having one or more disabilities. Many everyday features of our built environments are access barriers for people with certain disabilities. The Americans with Disabilities Act (ADA) has dramatically improved access since its effective date in 1992, especially in new buildings. California had access construction standards even before the enactment of the ADA. The combination of the ADA and pre-existing California access has resulted in a unique statutory framework that has resulted in an explosion of lawsuits. These lawsuits often target older buildings which were built before the code section forming the basis of the lawsuit.
