The Americans with Disabilities Act is a law guaranteeing comprehensive civil rights to
people with disabilities. The legislation requires "places of public
accommodation," "commercial facilities," and "transportation
facilities" be designed so as to be readily accessible to and usable by people with
disabilities.
To make your building accessible and usable you may be required to make some modifications
to your elevators. We have outlined the regulations applying to elevators in this booklet.
Should you find that you are not in compliance with the law, Stanley Elevator can
accomplish any upgrade that must be made quickly and cost efficiently. You may be eligible
for a Federal tax credit or Federal tax deduction to compensate for the costs associated
with ADA upgrades. Contact your tax consultant for details.
Please note that ADA is a Civil Rights legislation. As such, legal remedies include
injunctive relief, civil suits, and penalties up to $100,000.00 .

recommend that the legislation be reviewed for overall compliance in other areas which may

If you should have specific questions on how ADA legislation relates to your individual
situation, it is recommended that counsel be retained or
consulted. |
