MYTH:

The ADA requires businesses to remove barriers overnight.

FACT:

Businesses are only required to do what is readily achievable at that time.  A small business may find that installing a ramp is not readily achievable this year, but if profits improve it will be readily achievable next year. Businesses are encouraged to evaluate their facilities and develop a long-term plan for barrier removal that is commensurate with their resources.
