Accessibility AI
AI that verifies and enhances accessibility in building designs.
Definition
Accessibility AI automates the verification of building designs against accessibility requirements including ADA, Fair Housing, and local accessibility codes. These systems analyze floor plans for accessible routes, door clearances, restroom configurations, and other accessibility elements, flagging non-compliant conditions and suggesting corrections.
In Depth
Accessibility compliance is one of the most detail-oriented aspects of building design, involving hundreds of specific dimensional requirements across ADA, Fair Housing Act, and local accessibility codes. Manual checking is tedious and error-prone — it is easy to verify that a restroom door is 36 inches wide while missing that the maneuvering clearance on the push side is 2 inches short.
AI-powered accessibility checking systematically verifies every relevant dimension and requirement. It checks door maneuvering clearances, restroom fixture spacing, accessible route widths, ramp slopes and landing sizes, counter heights, and signage locations — all against the applicable code requirements. Each finding includes the specific code reference and the measured value from the drawings, so the architect knows exactly what to fix and why.
The time savings are significant. An experienced plan examiner might spend a full day reviewing a floor of a hospital for accessibility compliance. The AI can complete the same analysis in minutes, producing a detailed report that the examiner can then verify in an hour. This is not about replacing the examiner's judgment — it is about handling the measurement-intensive checking so the examiner can focus on the complex judgment calls that require human expertise.
