AMERICANS WITH DISABILITIES ACT: SCOPING ADA CHAPTER 2: SCOPING REQUIREMENTS
3. Residential dwelling units not required to be accessible in compliance with a standard issued
pursuant to the Americans with Disabilities Act or Section 504 of the Rehabilitation Act of 1973, as
amended, shall not be required to comply with 202.3.
Advisory 202.3 Alterations. Although covered entities are permitted to limit the scope of
an alteration to individual elements, the alteration of multiple elements within a room or
space may provide a cost-effective opportunity to make the entire room or space accessible.
Any elements or spaces of the building or facility that are required to comply with these
requirements must be made accessible within the scope of the alteration, to the maximum
extent feasible. If providing accessibility in compliance with these requirements for people
with one type of disability (e.g., people who use wheelchairs) is not feasible, accessibility
must still be provided in compliance with the requirements for people with other types of
disabilities (e.g., people who have hearing impairments or who have vision impairments) to
the extent that such accessibility is feasible.
202.3.1 Prohibited Reduction in Access. An alteration that decreases or has the effect of
decreasing the accessibility of a building or facility below the requirements for new construction at
the time of the alteration is prohibited.
202.3.2 Extent of Application. An alteration of an existing element, space, or area of a building or
facility shall not impose a requirement for accessibility greater than required for new construction.
202.4 Alterations Affecting Primary Function Areas. In addition to the requirements of 202.3, an
alteration that affects or could affect the usability of or access to an area containing a primary function
shall be made so as to ensure that, to the maximum extent feasible, the path of travel to the altered area,
including the rest rooms, telephones, and drinking fountains serving the altered area, are readily
accessible to and usable by individuals with disabilities, unless such alterations are disproportionate to
the overall alterations in terms of cost and scope as determined under criteria established by the
Attorney General. In existing transportation facilities, an area of primary function shall be as defined
under regulations published by the Secretary of the Department of Transportation or the Attorney
General.
EXCEPTION: Residential dwelling units shall not be required to comply with 202.4.
Advisory 202.4 Alterations Affecting Primary Function Areas. An area of a building or
facility containing a major activity for which the building or facility is intended is a primary
function area. Department of Justice ADA regulations state, “Alterations made to provide an
accessible path of travel to the altered area will be deemed disproportionate to the overall
alteration when the cost exceeds 20% of the cost of the alteration to the primary function
area.” (28 CFR 36.403 (f)(1)). See also Department of Transportation ADA regulations,
which use similar concepts in the context of public sector transportation facilities (49 CFR
37.43 (e)(1)).
There can be multiple areas containing a primary function in a single building. Primary
function areas are not limited to public use areas. For example, both a bank lobby and the
bank’s employee areas such as the teller areas and walk-in safe are primary function areas.
