If you’re designing or renovating a space with the intent of making it accessible, then you already know what knee clearance means. Under the Americans with Disabilities Act (ADA), this refers to the open space under fixtures like sinks or counters that allows someone using a wheelchair to roll up and use the feature comfortably.

It’s true that knee clearance ADA is an important part of accessible design, but it’s not always required. In fact, there are several situations where you can skip it altogether and it doesn’t mean you’re breaking the law. So, when is knee clearance not required under the ADA?

Scenarios where knee clearance ADA is not needed

1. When standing use is expected

The ADA only requires knee clearance where a feature needs to be accessed while the users are seated. For example, at an accessible sink or a service counter designed for people using wheelchairs. But if the feature is designed for standing position, ADA knee clearance is not needed then.

Consider things like high shelves, standard-height check out counters, or display tables. If they’re not designed to be accessible while users are seated and are part of a larger accessible layout, then knee clearance may not be required.

2. Fixed Storage Units or Cabinetry

There’s no need for knee clearance in built-in cabinets, closets or shelves. Especially if these fixtures are not on any accessible route or are not designed to serve the public. The ADA requirements for storage focus more on how a user is able to reach the top (typically 15 to 48” above the floor) rather than on clearance underneath. 

3. Non-accessible elements 

It’s not compulsory for every single element in a space to be ADA-compliant. For example, if there are two sinks in a kitchen, and only one is designated as accessible, only that one sink needs knee clearance underneath. The second sink is allowed to follow standard design without worrying about wheelchair access. This is common in shared workspaces, commercial kitchens or even public restrooms with multiple lavatories.

4. Wall-Mounted Fixtures Above Standard Height

There are some items that can only be installed on the walls like paper towel dispensers, hand dryers or coat hooks, these items don’t require knee clearance. You can access these items from a standing position or you may not need to get close to them before you can access them.

Exceptions based on use or location 

There are also cases in the ADA where knee clearance is impossible due to the structure of the building. For instance in historic buildings or older facilities where trying to modify the space would affect the building’s integrity. In these situations, it’s okay for areas in the building to not have knee clearance.

Conclusion 

Honestly, there are different cases where knee clearance isn’t required but it’s still a good idea to create spaces with accessibility in mind. When you design a building with accessibility in mind, it’s not just about meeting a code or complying with legal requirements, it’s to accommodate everyone and ensure that people find your space.
