There are two main reasons to comply:

1. Legal

First and foremost it's the law…

Title III of the Americans with Disabilities Act of 1990 (42 U.S.C. 12181) prohibits discrimination on the basis of disability by public accommodations and requires places of public accommodation and commercial facilities to be designed, constructed and altered in compliance with the accessibility standards established by this part.

What happens if my business is not compliant?

It's not if your business will be sued for A.D.A compliance violations, its when your business will be sued for A.D.A compliance violations.

If you are sued and are in violation, you have no defense. Many persons with disabilities feel discriminated by businesses where they cannot enter, properly use the facilities, or are made to feel like an outcast due to their disability. Many of the people who sue businesses for A.D.A violations are honest and just want the business they patronize or would like to patronize to adhere to the law and make the proper modifications.

Unfortunately, there are other less ethical people whose litigious motivations behind their A.D.A. violations suits are monetarily motivated. Either way, the defendant will still have to incur attorney's fees, court costs, possible fines and other legal fees to defend the suit.

At the end, most businesses end up paying around $15,000 to lawyers on both sides, $5,000 in court costs and still must hire a contractor to do the A.D.A modifications, all the while hoping the federal government or the state won't issue a fine.

2. Moral

We as Americans have a duty to follow the laws of this country and should do everything in our power help all of our citizens live their life free from discrimination and bias and enjoy the freedom which this country provides.
