Disproportionate costs and alternative
compliance.
Alterations
required to be made to provide an accessible path of
travel to the altered area will be deemed disproportionate to the overall
alteration
when the cost exceeds twenty per cent of the cost of
the alteration to the primary function area. The determination of
disproportionate costs is to be made and applied in accordance with the
following:
1.
Costs that may be counted as expenditures required to
provide an accessible path of travel may include:
1.1
Costs associated
with providing an accessible entrance and an accessible route to the altered
area, for example, the cost of widening doorways or installing
ramps;

Costs associated with making restrooms accessible, such
as installing grab bars, enlarging toilet stalls, insulating pipes, or
installing accessible faucet controls;

Costs associated
with providing accessible telephones, such as relocating the telephone to an
accessible height, installing amplification devices, or installing a

When the cost of
alterations
necessary to make the path travel to the altered area
fully accessible is disproportionate to the cost of the overall alteration, the
path of travel is to be made accessible to the extent that it can be made
accessible without incurring disproportionate costs.
2.2
In choosing which
accessible elements to provide, priority should be given to those elements that
will provide the greatest access, in the following order:
2.2.1.
An accessible
entrance;
2.2.2.
An accessible route to the altered
area;
2.2.3.

telephones;
2.2.5.
Accessible drinking fountains;
2.2.6.
When possible,
additional accessible elements such as parking, storage, and
alarms.
3.
Series of smaller
alterations
. The obligation to provide an accessible path of
travel is not to be evaded by performing a series of small
alterations
to the
area served by a single path of travel if those
alterations
could
have been performed as a single undertaking.
3.1
If an area
containing a
primary
function
has been altered without
providing an accessible path of travel to that area, and subsequent
alterations
of that area, or a different area on the same path of
travel, are undertaken within three years of the original
alteration
, the
total cost of
alterations
to the
primary
function
areas on that path of travel
during the preceding three year period is to be considered in determining
whether the cost of making that path of travel accessible is
disproportionate.

or ceiling finishes exposing the structure is not otherwise proposed. Listed
conventional battery-operated smoke alarms or listed battery operated low-power
radio (wireless) alarms are permitted to be installed in these existing
finished areas.
307.1.2

more than one smoke alarm is required to be installed within an individual
dwelling unit in accordance with Section
307.1, the alarm devices are to
be interconnected in such a manner that the actuation of one alarm will
