Apparently there are laws pertaining to this in several states. Forgive me if this was previously mentioned, I did not read every page, and only saw one prior legal reference, to Florida building code.

The Restroom Access Act, also known as
Ally's Law, is legislation passed by several U.S. states that requires retail establishments that have
public toilet facilities for their employees to also allow customers to use the facilities only if the customer suffers from an
inflammatory bowel disease or other medical condition requiring immediate access to a toilet.
As of April 2013, at least 14 U.S. states had passed versions of the law. They include Colorado, Connecticut, Illinois, Kentucky, Maryland, Massachusetts, Minnesota, Ohio, Oregon, Tennessee, Texas, Wisconsin, and Washington.
[2][3] A Virginia bill, which would have levied fines of $100 for non-compliance,
[4] was shelved due to concerns about exposing businesses to lawsuits, as well as concerns about security and intellectual property.

In general, each state requires that the customer present a document signed by a medical professional attesting that the customer uses an
ostomy device or suffers from
Crohn's disease,
ulcerative colitis, or other
inflammatory bowel disease or medical condition requiring access to a toilet facility without delay. In at least two states, Oregon and Tennessee, the customer can present an identification card issued by a national organization advocating for the eligible medical condition.

Some states also include pregnancy as a covered medical condition.
