Are condominiums in Massachusetts required by law & ADA to have handicapped spaces in the parking lot?

I am writing on behalf of my elderly and disabled mother. The HOA (she has lived there 18 years) repaved the parking lot and moved her spot away.

Who’s responsible when the sanitation company hired by the HOA causes damage to your car parked in the appropriate space belonging to your unit?

We live in a townhome community and residents leave cars out in the driveways and on the street.  Sometimes they do not move for months. 

I STAYED OVER A CONDO BUILDING UNDER AS AirBnB PERSON I HAD A GREEN STICKER PUT ON MY CAR SAYING I HAD TO MOVE IT FROM THE HANDICAPPED SPOT AFTER 2 HOURS PARKED THERE DUE TO AT NIGHT TIME IT WAS USED FOR EMERGENCY PARKING CAN THEY DO THAT ON HANDICAPPED PARKING SPACE HOW CAN DEAL WITH THIS ISSUE.

I live in a 3-unit condo building. T I'm looking for a parking space limit addendum form to file with the Registrar of Deeds. Can you help? Massachusetts
