Federal, and usually state law require accessibility to common areas.
Here are two things to try.
The most simple, that you can do today, is to contact your local building department and ask them to do an accessibility assessment. The building dept may require the COA to make changes that will make the common areas fully accessible. It may be possible to keep your name anonymous.
Another thing to do is to file a discrimination complaint.
You always have the right to file a complaint with both the state discrimination agency and the federal one, Housing and Urban Development (HUD). Commission (EEOC).
In Florida, you can contact the state agency here: http://fchr.state.fl.us/complaints__1
If you start with the state agency, in most states they'll file a complaint with HUD on your behalf at the same time.
The person who files the complaint should be someone in a wheelchair, or someone who has difficulty walking, and other wise is a person who needs the accessibility. Filing a discrimination complaint cannot be anonymous.
I have no idea how this will affect your run for the Board. Some people will probably think you're a hero; others will curse you because the association will have to put out a few bucks to make the physical changes.
I'll assume that I have answered your question and will "ACCEPT" my answer unless I hear back from you with follow-up questions.
Bonuses of even a few dollars are much appreciated.
I REALLY appreciate POSITIVE FEEDBACK!
