HOA disregarding reasonable let accommodation for parking

We live in a community with a very aggressive HOA. They have mandated that all residents park their cars in their garages. The issue is that the builder built extremely small garages and we would only be able to squeeze our cars in. If that were to happen, my wife who has severe arthritis and has been supplied with a handicap parking placard by CA DMV, would not be able to enter or exit her car. We presented our situation to the board of directors as well as the property management company. We were told they have exemptions for people with disabilities and would send us the forms. To date they have not sent the forms nor responded to emails and voicemail. They just sent another infraction notice listing fines and a requirement to attend another hearing. Do we have legal grounds to sue to protect our rights under ADA?
