Introduction to ADA
•
The Americans with Disabilities Act (ADA) sets guidelines for accessibility
to public restrooms and commercial facilities for individuals with
disabilities.
•
These guidelines are implemented during the design, construction, and
alteration of buildings and facilities.
8
ADA and Universal Design
• Accessibility is an important topic in design, especially
considering the growing elderly population and ADA standards.
• For this reason, there is an increasing emphasis on universal and
adaptable design. A comprehensive approach is now being
favored to ensure design sustainability in terms of accessibility.
ADA
9
Tax Deductions
•
A great incentive to ensuring the accessibility of restrooms is that the IRS
allows a deduction of up to $15,000 a year for costs associated with
making a facility more accessible to those with disabilities and the elderly
(barrier removal) where as general improvement costs must be
capitalized. This includes toilet rooms.
•
For more information, see Costs You Can Deduct or Capitalize of IRS
Publication 535 (www.irs.gov/publications/p535/).

ADAAG
In this course, we will review the ADA Accessibility Guidelines for Buildings
and Facilities (ADAAG) as related to restroom accessibility in addition to
implementation strategies and other sustainability and privacy
considerations.
11
UNDERSTANDING ACCESSIBILITY IN
THE RESTROOM SETTING
12
Understanding Accessibility in the Restroom Setting
• “A public accommodation shall remove architectural barriers in
existing facilities, including communication barriers that are
structural in nature, where such removal is readily achievable, i.e.,
easily accomplishable and able to be carried out without much
difficulty or expense.”
• When designing a public restroom facility, the designer should
walk through the restroom, making themselves aware of which
items in the design they need to be sensitive to such as:
clearances, reach limits, mounting heights on accessories, door
swings, lighting, location of accessible toilet compartments, etc.
13
access-board.gov; Jan 2011
Examples of Steps to Remove Barriers
Include, but are not limited to, the following actions:
• Installing accessible door hardware
• Installing grab bars in toilet stalls
• Rearranging toilet partitions to increase maneuvering space
• Insulating lavatory pipes under sinks to prevent burns
• Installing a raised toilet seat
• Installing a full-length bathroom mirror
• Repositioning the paper towel dispenser in a bathroom
14
Measures To Provide Access
A public accommodation should take measures to provide access to
restroom facilities. These measures, for example, include:
• Removal of obstructing furniture or vending machines
• Widening of doors
• Installation of ramps
• Providing accessible signage
• Widening of toilet stalls
• Installation of grab bars
15
Circulation Path
As you move through the designed areas, carefully consider
entrance to and travel about the restroom. Obstacles will need to be
removed in order to create an acceptable passage width.
Wheelchair Passage Width
4.2.1 Wheelchair Passage Width. The minimum clear width for single wheelchair
passage shall be 32 in (815 mm) at a point and 36 in (915 mm) continuously.
16
Circulation Path
• Also consider multiple use of restroom by persons with disability
barriers.
• Provide adequate space for passage
Width for Wheelchair Passing
4.2.2 Width for Wheelchair Passing. The minimum width for two wheelchairs to
pass is 60 in (1525 mm).
17
Maneuverability and Turning
The restroom you are designing will likely require the need to incorporate the
60” Wheelchair Turning Space. This can be accomplished by laying out your
toilet partitions in such a way to allow the circle to be outside the accessible
toilet stall before entry.
Wheelchair Turning Space
4.2.3 Wheelchair Turning Space. The space required for a wheelchair to make a
180-degree turn is a clear space of 60 in (1525 mm) diameter (see Figure a) or a
T-shaped space (see Figure b).
18
Clear Width Doorways
4.13.5 Clear Width Doorways. Doorways shall have a minimum clear opening of 32
in (815 mm) with the door open 90 degrees, measured between the face of the door
19
and the opposite stop .
Clear Width Doorways
Beginning with the very entrance into the restroom as well as entry
into an accessible toilet compartment, minimum clearances are both
critical and mandatory
Maximum Doorway Depth
4.13.5 Clear Width. Openings more than 24 in (610 mm) in depth shall
comply with 4.2.1 and 4.3.3.
20
Accessible Handles
Consider the use of accessibly designed hardware for entry doors on
restroom entrances, toilet compartment entries, door pulls, and
automatic door openers.
4.13.9 Door Hardware. Handles, pulls, latches, locks, and other operating devices
on accessible doors shall have a shape that is easy to grasp with one hand and does
not require tight grasping, tight pinching, or twisting of the wrist to operate.
21
Height and Reach Restrictions
Both mounting height and reach restrictions need to be considered
when vanities are incorporated into the design. Vanities can be
mounted at various heights to achieve a vanity that is accessible.
22
IMPLEMENTING ADA GUIDELINES
23
Accessible Toilet Stall Location
4.17.1 Location. Accessible toilet stalls shall be on an accessible route and shall meet
the requirements of 4.17.2 through 4.17.6 (Location, Water Closets, Size &
24
Arrangement, Toe Clearances, Doors, Grab Bars). Information on following slides
Configuration – Water Closet
4.16 Water Closets
Clear space for toilet and sink
• 36” x 36” clear use area
• 30” x 48” clear use area
Maneuvering space
• 30” x 48” turning area
• 60” diameter turning area
Note: Door swing cannot
overlap the 5' turning radius
by more than 1 foot
25
Configuration – Water Closet (non-stall application)
See figure below for design options that meet ADA Code.
Water Closet Clear Floor Space for Toilets
4.16.2 Clear Floor Space. Clear floor space for water closets not in stalls shall
comply with the above figure. Clear floor space may be arranged to allow either a
left-handed or right-handed approach.
26
Configuration - Stalls
4.17 Toilet Stalls
Toilet Compartments - A toilet compartment is a
partitioned space that is located within a toilet
room, and that normally contains no more than
one water closet. A toilet compartment may also
contain a lavatory. A lavatory is a sink provided
for hand washing. Full-height partitions and door
assemblies can comprise toilet compartments
where the minimum required spaces are provided
within the compartment.
4.17.2 Water Closets. Water closets in accessible stalls shall comply with 4.16.
Refer to Water Closet Slides 28-32
27
Toilet Stalls, Size & Arrangement
Standard Stall
The size and arrangement of the standard toilet stall shall comply with above
figure, Standard Stall. Standard toilet stalls with a minimum depth of 56 in (1420
mm) shall have wall-mounted water closets.
28
Standard Stall
If the depth of a standard toilet stall is increased at least 3 in to 59 in
(75 mm), then a floor-mounted water closet may be used.
29
Alternate Stalls
EXCEPTION: In instances of alteration work where provision of a standard stall is
technically infeasible or where plumbing code requirements prevent combining
existing stalls to provide space, either alternate stall pictured above may be provided 30
in lieu of the standard stall.
Arrangements shown for
standard toilet stalls may be
reversed to allow either a
left or right-hand approach.
31
Toilet Stall Toe Clearances & Doors
4.17.4 Toe Clearances. In standard stalls, the front partition and at least one side
partition shall provide a toe clearance of at least 9 in (230 mm) above the floor. If
the depth of the stall is greater than 60 in (1525 mm), then the toe clearance is not
required.
4.17.5 Doors. Toilet stall doors, including door hardware, shall comply with 4.13.
If toilet stall approach is from the latch side of the stall door, clearance between the
door side of the stall and any obstruction may be reduced to a minimum of 42 in
(1065 mm).
32
Grab Bars (non-stall applications)
When selecting grab bars, consider longer and textured grab bars
that give more options for grabbing hold and also provide a non-slip
surface.
4.16.4 Grab Bars. Grab bars for water closets not located in stalls shall comply with
4.26 and above figures. The grab bar behind the water closet shall be 36 in (915 mm)
33
minimum.
Grab Bars (stall applications)
4.17.6 Grab Bars. Grab bars complying with the length and positioning shown in
the above figures shall be provided. Grab bars may be mounted with any desired
method as long as they have a gripping surface at the locations shown and do not
obstruct the required clear floor area. Grab bars shall comply with 4.26.
34
Water Closet Height
The height of the toilet is very important for meeting the needs of
persons with disabilities.
Toilet Height
4.16.3 Height. The height of water closet shall be 17 in. to 19 in. (430 mm to 485 mm)
measured to the top of the toilet seat (see Figure b). Seats shall not be sprung to return to
35
a lifted position (see appendix note in guidelines for age specific heights).
Water Closet Flush Controls
Design professionals cannot go
wrong in specifying automatic
flush valves. In addition to
removing a sometimes difficult
and frustrating step for persons
with disabilities, automatic flush
valves keep restrooms cleaner
and more sanitary.
Automatic Flush Valve
Manual Flush Valve
4.16.5 Flush Controls. Flush controls shall be hand operated or automatic and
shall comply with 4.27.4. Controls for flush valves shall be mounted on the
wide side of toilet areas no more than 44 in (1120 mm) above the floor.
36
Water Closet Dispensers
Specify a toilet paper dispenser that
makes toilet paper easy to reach and
obtain.
4.16.6 Dispensers. Toilet paper dispensers shall be installed within reach, as
shown in figure (b) above. Dispensers that control delivery, or that do not
permit continuous paper flow, shall not be used.
37
Urinals - Height
Keep in mind that not all persons
with disabilities are using
wheelchairs. In the case of urinal
screens, not only width between
urinal screens is critical but also the
mounting height. Accessible
Urinals serve not only persons with
disabilities, but also youth.
4.18.2 Height. Urinals shall be stall-type or wall-hung with an elongated rim at a
maximum of 17 in (430 mm) above the finish floor.
38
Urinals, Clear Floor Space
4.18.3 Clear Floor Space. A clear floor space 30 in by 48 in (760 mm by 1220
mm) shall be provided in front of urinals to allow forward approach. This clear
space shall adjoin or overlap an accessible route and shall comply with 4.2.4.
Urinal shields that do not extend beyond the front edge of the urinal rim may be
provided with 29 in (735 mm) clearance between them.
39
Lavatories and Mirror Height and Clearances
Lavatory Clearances
Height and Clearances. Lavatories shall be mounted with the rim or counter
surface no higher than 34 in (865 mm) above the finish floor. Provide a clearance
of at least 29 in (735 mm) above the finish floor to the bottom of the apron. Knee
and toe clearance shall comply with above figure.
40
Lavatories and Mirrors, Clear Floor Space
Design with ample space around
Lavatories to allow for easy access
Clear Floor Space. A clear floor space 30 in by 48 in (760 mm by 1220 mm)
complying with 4.2.4 shall be provided in front of a lavatory to allow forward
approach. Such clear floor space shall adjoin or overlap an accessible route and
shall extend a maximum of 19 in (485 mm) underneath the lavatory.
41
Faucets
Faucets should extend far enough & high enough
for the individual to place hands under faucet.
Automatic
Manual
4.19.5 Faucets. Faucets shall comply with 4.27.4. Lever-operated, push-type, and
electronically controlled mechanisms are examples of acceptable designs. If self-closing
valves are used the faucet shall remain open for at least 10 seconds.
42
Exposed Pipes and Surfaces
The use of under Lav Protectors is key to protecting legs and knees
from hot water lines or sharp plumbing attachments. They also
provide a clean, more finished look.
ADA under Lav Protectors
4.19.4 Exposed Pipes and Surfaces. Hot water and drain pipes under lavatories
shall be insulated or otherwise configured to protect against contact. There shall be
no sharp or abrasive surfaces under lavatories.
43
Lavatories and Mirrors
Lavatory Clearances
4.19.6 Mirrors. Mirrors shall be mounted with the bottom edge of the
reflecting surface no higher than 40 in (1015 mm) above the finish floor.
44
SUSTAINABLE ADA AND
ENVIRONMENTAL DESIGN SENSITIVITY
45
Sustainable ADA & Environmental Design Sensitivity
• Creating restrooms that will meet the needs of persons with
disabilities both today and in the future is very important.
• We know that needs may change over time and items within the
restrooms (i.e.: water closets, accessories, sizes, locations) may
change as needs change or issues arise, but one fact remains
constant—the need to consider these individuals and their
disabilities and act to remove the barriers that they encounter.
• In addition, a restroom that has ample space, lighting, ease of
maneuvering, etc. will help toward creating a more sustainable
restroom—meeting needs both now and in the future.
46
Sustainable ADA & Environmental Design Sensitivity
• Knowing that all restrooms over time with the amount of use they
receive will be in need of a “freshening up,” it is very important to
use products that can be recycled.
• Certain manufacturers of toilet partitions produce nearly 40 million
pounds of product annually. Imagine 25-40 years from now when
that building needs to be renovated or razed…
…where will those products go?
47
Sustainability, LEED & Environmental Design Sensitivity
Specify partitions and other fixtures that not only contain recycled content,
but are also recyclable
Some
manufacturers offer
a program by which
all unwanted solid
HDPE plastic
products can be
returned for
recycling.
MR Credit 2: Construction Waste Management
By implementing a waste management plan for at least 50-75% of construction
materials, a project may earn 1-2 points toward LEED Certification.
48
Diverting plastic from the landfills into new products that can be reused again
& again is one way we can make a difference in the outcome of millions of
pounds of garbage annually polluting our environment. It is truly up to each
of us to make an impact where we have influence.
MR Credit 4: Recycled Content
Use materials with recycled content such that the sum of postconsumer recycled content
plus 1/2 of the preconsumer content constitutes at least 10% or 20%, based on cost, of the
total value of the materials in the project. The recycled content value of a material assembly
is determined by weight. The recycled fraction of the assembly is then multiplied by the
cost of assembly to determine the recycled content value.
49
What decision will you
be responsible for???
Some manufacturers offer
products of 100% Post
Consumer Recycled HDPE
solid plastic in a variety of
colors, and standard HDPE
solid plastic products of 25% 70% post industrial recycled
HDPE.

PRIVACY DESIGN OPTIONS
51
Privacy Design Options
Zero Sight Line Toilet Compartment
52
Eliminating Sight Lines – Continuous Strike Elevation
Eliminating Sight lines into the toilet compartments gives added
privacy & security for persons with or without disabilities. This
consideration may be a particularly sensitive one for disabled
persons.
Zero Sight Line Front Elevation
53
Eliminating Sight Lines – Continuous Strike Plan
The plan view below shows how the sight lines are removed by using
a continuous hinge & a continuous strike.
Zero Sight Line Latch & Hinge Plan Detail
54
Eliminating Sight Lines – Continuous Strike Detail
Adding a continuous aluminum strike can
provide zero sight lines without having to
alter or machine pilasters or doors, this
allows for retrofitting and quick lead times
55
Eliminating Sight Lines – Continuous Strike Latch
When designing or retro fitting for
max privacy toilet partitions,
consider the use of a full height
continuous aluminum strike.
This eliminates the line of sight
into the toilet compartment.

Summary
• As we each come to realize the influence we have in changing
our surroundings and the potential impact on the spaces we use,
sensitivity to create restrooms that will meet the needs of each
person, regardless of their abilities or disabilities, is a must.
• Being mindful of the obstacles within restrooms, creating
sustainable restroom design, and specifying building products that
can be recycled and reused will ensure our restrooms are wellequipped for today and tomorrow.
• Considering we spend on the average 5 years of our life in the
restroom, making it clean, safe, and comfortable for everyone is
worth our efforts!
