The Assessment of Non-Feasibility of Accessibility Adjustments must be prepared for each publicly accessible building by 13 July 2026 and must, together with supporting documentation, demonstrate the reasons why specific accessibility adjustments for persons with disabilities have not been implemented. It includes basic building data, already implemented measures, a precise definition of non-feasible measures with evidence, and justifications (technical infeasibility, safety reasons, disproportionate burden, or heritage protection), as well as consideration of alternative ways of ensuring access to services.
