YES! is short answer to complicated circumstances. If the facility was built before 1993, CFR Sec36.304 Removal of Barriers items (11) to (17) require retrofit per the 1991 (old) ADAAG. If the facilities were built 1993 to 2012 to the 1991 ADAAG standards you have "safe harbor" under the 2010 amendment Sec 36.304(d)(2)(i) - until you alter that facility or element.
That a facility complied with building or plumbing code has no standing under ADA which is civil rights for the disabled which overrides a lesser accessibility standard. Conflicting standards are usually resolved by the someone's judgement as to which provides the greater degree of accessibility.
As an ADA consultant, I can always find items or elements that are not in compliance either because of deficient design or poor construction management. So can the Lawyers or advocates whose fees are guaranteed per Sec 36.505 Attorneys Fees. Sooooo have a talk with your attorney and insurer re: an affirmative defense to this.
