# Readily achievable barrier removal

The ADA's duty to remove access barriers from an existing building.

It is the building obligation that does not grandfather. New construction has to meet the design standards outright. An older building has to remove barriers wherever doing so is easy and inexpensive, measured against the business as it stands. A buyer inherits that duty on the day they close, and the size the test is applied against becomes the buyer's own. Two things follow in diligence. Price the obvious items, a parking space, a door width, a ramp, a restroom stall, before somebody else prices them in a demand letter. And ask whether the premises have ever drawn a complaint, because the duty attaches to whoever operates the premises, so a change of owner does not reset it, and a plaintiff who has written once about a property commonly writes again.

In numbers: The 2010 Standards cap a ramp at a 1:12 slope, which is 8.33%, so a 6 inch rise needs 6 feet of run. An existing building short of space may use 1:10 for that rise, or 5 feet, and a 32 inch clear door width is the floor.

Not dated: A definition is editorial: what a term means, why it matters, and an example. None of it reads a source that can go stale, so there is no date to take and a stamped one would be the build time wearing a costume.
