The minimum knee clearance under a sink for ADA is ______ inches above finish floor.

The minimum knee clearance under a sink for the Americans with Disabilities Act (ADA) is set at a height of 29 inches above the finish floor. This requirement ensures that individuals using wheelchairs or those who may have difficulty standing can access the sink comfortably. The 29-inch measurement facilitates not only the physical space needed for a wheelchair to fit but also promotes usability when reaching for fixtures such as faucets and soap dispensers.

Additionally, compliance with this standard is crucial for creating accessible environments in public facilities, ensuring that everyone has the opportunity to use the sinks without obstruction. While other heights may be mentioned in different contexts or regulations, the ADA specifies 29 inches as the baseline for ensuring adequate knee clearance.
