Accessibility Audit

An accessibility audit measures an environment against a specific accessibility standard or code to determine compliance and document barriers, with pass/fail judgments tied to numeric criteria such as door widths and ramp gradients. A universal design evaluation is broader and aspirational, judging how well a design serves the widest range of people without adaptation against the seven principles of universal design. An environment can pass a code audit while still scoring poorly on universal design—for example, if its accessible route is separate and stigmatizing. Audits set the legal floor; universal design evaluation pushes toward equitable use for all.

The WHO International Classification of Functioning, Disability and Health treats disability as arising from the interaction between a person and their environment, and it lists environmental factors that can act as facilitators or barriers. An accessibility audit is, in effect, a structured measurement of exactly those physical environmental factors. By framing the audit through the ICF, the auditor connects each measured feature to the activities and participation it enables or obstructs, which is what justifies classifying some barriers as far more disabling than others and prioritizing their removal accordingly.

Because remediation budgets are finite and not every non-conformance disables to the same degree. A non-conforming main entrance that everyone must use is far more consequential than a minor shortfall in a seldom-used space, and some fixes are cheap while others are major works. Ranking by severity—how far the element departs from requirement, how heavily it is used, and how large the affected population is—and weighing that against cost lets owners remove the most disabling barriers first. An unranked list of every defect, by contrast, gives no guidance on where to start and often stalls action altogether.
