Businesses and non-profit organizations are required by the ADA to remove architectural barriers when it is "readily achievable" to do so.
“Readily achievable” means "easily accomplished without much difficulty or expense." The obligation for barrier removal is ongoing, which means a business must continue to evaluate existing barriers to determine if the barrier removal is readily achievable. In order to identify barriers in a facility, a business or non-profit should conduct an accessibility evaluation.
Determining what is “readily achievable” is made by each business on a case-by-case basis based on the size and resources of the business. First, facilities should be assessed to determine what architectural barriers exist. Second, the costs of barrier removal should be documented and barrier removal priorities and timelines established. Third, this information can be used to create a "barrier removal plan."
If physical construction or alterations to local government facilities were started on or after March 15, 2012, then new construction and alterations must comply with the 2010 Standards for Accessible Design. Before that date, the 1991 Standards (without the elevator exemption), the UFAS, or the 2010 Standards may be used for projects when the start of construction commences on or after September 10, 2010.
