What is the maximum height for changes in level on floors and ground surfaces allowed without a ramp?

The maximum height for changes in level on floors and ground surfaces without the need for a ramp is 1/4 inch. This standard is aligned with the guidelines in various building codes regarding accessibility and safety. When surfaces have a height differential exceeding this limit, it can pose a tripping hazard or hinder mobility for individuals with disabilities. Therefore, to ensure safety and compliance with accessibility requirements, a ramp or sloped transition must be provided for differences in height that exceed 1/4 inch. This regulation emphasizes the importance of creating safe and accessible environments in buildings and public spaces.
