Comments on point, thank you.Building built pre-ADA, owner has a ongoing duty to remove existing barriers subject to structural, space and cost limitations spelled out in the ADA and to maintain where necessary, those items requiring periodic adjustment (closer pressure) or refreshing (paint stripes), etc.
The longer they delay, the greater the risk of a complaint/suit occurring, especially with CA law now requiring disclosure as to whether a CASp survey has been performed or not.
There remains the misunderstood belief that if buildings are old (pre-ADA) and no work has been performed that they are grandfathered.
