Adaptability Adaptability is a concept whereby sinks,
counters, and grab bars are installed so they can be readjusted to
different heights for different people. This feature helps everyone not
just those who are short or use wheelchairs. Adjustable brackets on
kitchen and bathroom counters and sinks as well as continuous 3/4" wood
blocking in the walls surrounding a toilet or bathtub allow for
adjustability in the fixtures or grab bars at each location. Installing
this type of detail into a new house can eliminate the need for costly
renovation. What's more, adaptable elements won't change the appearance of
a house if they're carefully constructed. A home can easily be re-modified
to a "standard" appearance should you decide to sell the house and move at
a later date.
Accessibility During the past decade, building codes based on
the American National Standards Institute's Specifications for Making
Buildings and Facilities Accessible to and Useable by Physically
Handicapped People have made public buildings accessible to our entire
population. These building codes, which are generally applicable only to
stores, banks, and other public buildings, have generated new ideas for
achieving accessibility in private homes. Many of these ideas are
described and illustrated below.
Accessible Routes  A continuous corridor that's 3' wide,
6-8' high, and free of hazards and abrupt changes in level should connect
all important areas of your home. This pathway should lead from the point
where you enter the property, through the entrance to all important rooms.
If such an "accessible route" is available, anyone, regardless of physical
limitations, will be able to move easily around your home. If you rent
your home, check with your landlord before you undertake any
modifications.
Accessible Appliances You should try to strike a balance
between safety and useability in your home, especially if very old and
frail persons or very young children are present. For example, you may not
want a stove with front controls if your grandchildren visit frequently.
However, many barrier-free design specialists recommend front controls so
persons in wheelchairs won't have to reach across heated burners.
Doors The freedom to move easily around our homes is
something most of us take for granted. But it's a freedom that's cherished
by those with limited mobility and strength. Many of our homes were
designed with strong young families in mind. However, when older persons
occupy these houses, they may not be able to open some windows, climb
steps, or go through doors, especially if they have limited strength or
hand dexterity, or use a wheelchair or other mobility device.
Deciding which doors to make accessible isn't difficult when you
consider the main activities you enjoy. In your home, you should have easy
access through at least one entry door (preferably two for fire evacuation
reasons) and all doors along the accessible route between your bedroom and
the kitchen, dining, bathroom, living or family room, and possibly the
laundry room. Some doors may not need to be accessible, especially if they
lead to seldom-used areas or rooms such as basements, shallow closets, or
guest bedrooms.
There are four major reasons why people have difficulty using
doors:
Width Although the standard doorway width is 32", some
doorways may be narrower, and unable to accommodate wheelchairs or other
mobility assisting devices.
Landing The floor space on either side of the door is too
small to allow a person who uses a wheelchair or other mobility assisting
device to approach and open the door.
Hardware The latch or lock is located where it's hard to
reach and operate, or more commonly, the type of latch, lock, or handle is
difficult to operate by someone who has limited hand dexterity.
Weight The door is too heavy or the automatic door closer or
spring pressure is too strong to open easily. Each of these conditions has
several solutions:
Width Problems A standard wheelchair is 24-27" wide. When you
add 1 1/2" on both sides of the chair to allow for finger and knuckle
clearance, plus an inch or two to allow for inaccurate maneuvering and the
usual oblique approach to doors, the clear opening width totals 32".
Therefore, this standard is used in most building codes.
A swinging door is commonly available in a 3' width, but 3'
inward-opening doors are generally used only as front doors on most homes.
It's especially difficult to find doors of this width on bathrooms
(builders used to think bathrooms would never have furniture moving
through them). The usual reason for providing 3' doors is to allow for
easy furniture movement. Short of replacing the entire door and frame with
a wider doorway, there are several solutions to the narrow door problem.
Swing Clear Hinges You can replace the existing hinges on
your doors with "swing-clear hinges." They enlarge the clear opening of
the door by 1 1/2- 1 3/4 " (the thickness of the door itself). This
additional clearance is often enough to provide the necessary minimum
width for a wheelchair to pass through the doorway, though it may be a
tight squeeze. If the clearance is minimal, you may want to affix a piece
of plastic laminate or sheet metal on the door so wheelchairs won't mar
the surface as they pass through the doorway.
Remove Door Stops You can often remove the small wooden door
stops which create a stop for swinging doors and re-install them up to 3'
above the floor. This will add an additional 3/4" to the clear opening
width of the doorway, which may be enough to allow a wheelchair to pass
through.
Remove Doors If you remove existing doors you can provide an
additional 1 1/2-2" of clear door opening. If you also remove the door's
stops as mentioned above, you'll gain an additional 3/4" and a total of 2
1/4 - 2 3/4" will be added to the clear width of otherwise inaccessible
doors.
You may want to simply remove the pins from the hinges and remove the
door in some doorways. In other locations, where aesthetics are a
consideration, you can remove the hinges, door stops, and other hardware,
fill the resulting holes with wood putty or spackle, and repaint or
refinish the door frame. Before you remove hinges altogether, make sure
you'll never want to reinstall the door in the doorway. Reinstallation may
be fairly difficult once your door frames have been modified.
Landings Small landings on either side of doors can create
problems if you or others in your home use mobility devices. It is
difficult to pull a swinging door open if you, your wheelchair, or another
mobility device already occupy the landing area over which the door must
swing.
Usually 18-24" is needed beyond the strike jamb on the pull side of the
door to allow enough room for a wheelchair user to easily open the door.
Unfortunately, to enlarge a landing you may have to relocate walls or
partitions. This may be a difficult task, especially in older homes where
walls or partitions bear the weight of the house or where electrical or
plumbing lines are located. Two alternatives are available. You can either
remove the door from the doorway and eliminate the need to open or close
it, or you can install an automatic door opener. Either option will
eliminate the need for a wide door landing.
Hardware Hardware choices include latches, locks, thresholds,
kickplates, vision panels, and door openers. Depending on your needs, all
or some of these options may be appropriate in your home.
Latches Latches are a means of keeping doors closed. If a
latch isn't necessary (i.e. spring loaded, or well-balanced doors), you
may prefer to deactivate it. Anyone can push open a door, or pull it shut
if there is no excessive weight involved and the hardware for pulling the
door is easy to grasp. When latches are required, you may want to install
a device that requires no fine gripping or strong twisting ability. Lever
hardware is ideal, but high quality is usually available only in
"mortised" latches. If your home isn't newly built, you'll probably be
able to replace the existing knob hardware on your mortised lock sets with
levers.
Most residential construction uses cylindrical lock sets and latches
which are difficult to replace with levers. But several devices have been
introduced recently for adding a lever arm to existing cylindrical latch
sets. For information about these products, refer to the Resources
chapter.
Locks The security you desire for your home may be difficult
to achieve if you have hand dexterity impairments. Most locks require fine
dexterity and finger strength. Using the closed fist rule, you can easily
determine whether your locks are useable by older persons in your
household who have arthritis. Lever hardware is preferable to any kind of
small twist knob. Push buttons may be satisfactory if they don't require
fine dexterity to release the lock. A push button lock in a cylindrical
lever latch is perfect from an operational point of view, but it doesn't
generally provide the security of a dead bolt mechanism.
Slide bolts, however, are fairly easy for anyone to operate and provide
nearly the same security as dead bolts.
A lever arm welded or attached to an existing turn knob, may be an
acceptable way to adapt your door locks. Magnetic card readers, remote
control locks, and combination locks which are push-button activated work
well for many people. If you have key locks which retract dead bolts
(mortised locksets), you may be able to attach a dowel or other lever arm
to the key. This makes it easy for persons with limited finger strength to
operate and retract the dead bolt.
Thresholds Abrupt changes in levels greater than 1/2" can
create tripping hazards for people with walking problems and barriers for
people who use wheelchairs. Thresholds should be ramped or removed so they
do not create any type of barrier.
To remove a threshold, you must either cut or pry up and patch the
flooring at wooden thresholds, or replace metal or masonry thresholds with
others that have a lower profile. In some cases, you may be able to
install a beveled ramp that abuts the edge of the threshold and eliminates
the wheeling and tripping barrier.
Alternatively, you can fill the area with mortar or plastic material
that will level the approach to the threshold. You should try to eliminate
the threshold completely, however, since even a gradual ramp may create
problems for some residents or visitors in your home. Analyze the
abilities of the members of your household to determine what's best for
you and those who live with you.
Doormats Doormats, while helping to keep your house clean,
can create tripping hazards. Secure doormats to the floor surface or
recess them to be flush with the surface so they don't create an edge
profile that can cause someone to trip. Since doormats can also slip and
slide around on the floor, you should fasten them in place with tacks,
staples, or double-sided carpet tape.
Kickplates Where a doorway is especially narrow or someone
habitually pushes the door open with wheelchair foot rests, excessive wear
can occur. Oversized kickplates can reduce this wear. Kickplates should
extend from the floor surface up to a height of at least 10" and
preferably 16". You can fasten plastic laminate, metal, and even hardwood
kickplates to the door to provide protection. Kickplates should be as thin
as possible so they won't reduce the clear door width opening.
Vision panels If you have interior passage doors that you
normally leave closed, you may want to install vision panels in them so
that slow-moving persons won't be knocked over by others coming through
the door. These panels should be located as shown in the illustration.
For security reasons, you may want to provide oneway vision panels
and/or peepholes on entrance doors. This will allow you to visually survey
any visitor before you open the doorway and expose yourself to risk. For
people in wheelchairs, peepholes should be located approximately 36-45"
above the floor.
Automatic operators If one or more of your doors are
difficult to open because they are excessively heavy or the landings are
small, you may want to install automatic door openers. A simple system of
pulleys and weights as shown in the illustration may be a satisfactory
solution for doors where access is a problem.
Electro-mechanical openers that plug into an electrical outlet and are
operated from a remote button or sensor are effective for many
installations. For information about the availability of these products,
refer to the Resources chapter.
Pneumatic systems like those at supermarkets require compressors and
piping, and are generally much more expensive than the electromechanical
systems mentioned above. Automatic operators are available for sliding or
swinging doors. Refer to the Resources chapter, for the names of
manufacturers.
Door Types If you plan to modify or replace doors for better
accessibility, remember that several types of doors may be suitable.
Swinging doors are the most common, but they require landings on both
sides.
Sliding doors are often useful when space is limited, but their weight
and lateral movement can cause problems for some disabled people. And some
sliding doors require a floor track that can create a tripping or wheeling
problem for some individuals. Threshold modification may be necessary.
Folding doors are another option. They require lateral force, but are
generally lighter in weight than most other doors. However, the hardware
for these types of doors will sometimes not withstand constant use.
Pocket doors are becoming more and more fashionable. Where there is
only an occasional need for privacy they're especially effective. When
they aren't being used, they're out of the way and out of sight (hidden in
a wall).
Pocket doors can also be inexpensively mounted on the surface of an
existing wall, but are less aesthetically pleasing than hidden doors.
