As you are probably aware of, Accessibility has two portions - local state/city and Federal ADA. The local codes are typically enforced at the time of permit or construction and is not required to be updated to new codes when no construction is being done. The ADA is a civil rights law and is an ongoing obligation.
So, in answer to your question - it depends. If the facility is a place of public accommodation, as you stated, and was constructed
pre-ADA, then the owner/tenant is obligated to remove barriers which are
Readily Achievable (RA) on an ongoing basis even if there is no construction or alterations and even if it met all local building codes. The Department of Justice (DOJ) has a list of what they consider Readily Achievable, although it is not finite, and also a 5-point criteria of what makes something RA which is mostly financial concerns. Because of this, we as architects, unless we are also CPAs or Attys, do not determine what is RA for a owner/tenant, although you certainly can provide the list that DOJ created.
If a building was constructed
post-ADA then it is required to meet all ADAAG requirements. If it does not, even if it met local codes, and even if there is no construction, it should be altered to meet ADA. And right now it should then be altered to meet the 2010 ADAS.
There is now
Safe Harbor which basically states that if an element met ADAAG then it does not need to be altered to meet the 2010 ADAS unless that specific area is being altered. This does not apply to certain types of elements that were not covered in the original ADA (ie pools, spas, exercise area, etc)
There is also an element that many times confuses people. If you
are doing an alteration, there is the 20% rule which requires you to spend additional money on making Path of Travel items accessible. Above the 20% it is considered
disproportionate and is not mandatory. Of course, here in CA where I live, the 20% disproportionate rule disappears when we hit the Valuation Threshold (it is now $136,060) and in that case all supporting Path of Travel items are required to be altered to comply.
All of the above are just brief overviews and there are a number of exceptions and qualifications.
