Indoor Accessibility

The degree to which indoor spaces — including homes, workplaces, and public buildings — can be safely and independently used by people with disabilities. Indoor accessibility encompasses physical features such as door widths, counter heights, light switch placement, grab bar availability, and floor surface conditions. In the United States, approximately 90% of housing units have accessibility issues like entrance steps and narrow doorways. Indoor accessibility auditing, whether through manual checklists or emerging automated tools using computer vision and LiDAR, helps identify barriers and plan modifications to make spaces safe and usable for people with diverse abilities.
