What is the minimum front-to-door distance for all non-ADA fixtures?

The minimum front-to-door distance for all non-ADA fixtures must be 21 inches. This measurement ensures that there is sufficient space in front of the fixture to allow for comfortable usage and access, particularly in situations where a door may swing open. Maintaining a minimum distance of 21 inches helps prevent obstruction and allows users to approach and utilize the fixture without hindrance, promoting safety and functionality within the design of bathrooms and other spaces where plumbing fixtures are located. Understanding this requirement is key for compliance with various building codes, which aim to ensure that all spaces are designed with user accessibility and convenience in mind.
