ADA Safe Harbor Clause

(C) Safe harbor. If a public entity has constructed or altered required elements of

a path of travel in accordance with the specifications in either the 1991

Standards or the Uniform Federal Accessibility Standards before March 15,

2012, the public entity is not required to retrofit such elements to reflect

incremental changes in the 2010 Standards solely because of an alteration to

a primary function area served by that path of travel.

NOTES:

• Burden of proof related to date of construction and compliance with prior

standard is upon the public entity.

• If the element is subsequently altered, it falls under the current standards

and requirements.
