ADA Compliance

Do you have door thresholds that allow for accessibility? ADA compliance, per the Americans With Disabilities Act, is important when doing flour or ground renovation.

Whether you are putting fire doors in a business or exterior hinged doors in a residence, you need to aim for an accessible entrance. ADA standards mean that wheelchair users can safely enter and exit buildings.

How We Make Accessible Doors

All of our thresholds are designed to meet ADA requirements as long as they are installed properly and as directed. Marble thresholds are to be recessed to the floor adjacent to it. Only the bevel part is to be raised off the floor, and the bottom part is to be recessed. Please see the drawings below for a demonstration of the door opening.

ADA Threshold Requirements

 

Generally, ADA compliance focuses on threshold height and thickness. Why? Because uneven thickness between thresholds, doors, and floors can bar a person from using mobility aids from entering or exiting an area. Public facilities such as museums often demonstrate this issue with exit and entry doors; a contractor can do better with a residential home.

ADA Threshold Height And Thickness Requirements

The ADA requirements for thresholds comprise the following:

  • Thresholds, if provided at a doorway, must not exceed 3/4 inch in height for exterior sliding doors or 1/2 inch for other types of doors.
  • Changes in level up to 1/4 inch can be vertical and do not need an edge treatment.
  • Changes in level between 1/4 inch and 1/2 inch must have a beveled slope equaling 1:2

Our standard thicknesses for  4″ and wider thresholds are 5/8″, and 3/8″ or 1/2″ for 2″ wide thresholds.

Standard Bevel Thresholds have 1/4″ Bevels on 2 long sides. Hollywood thresholds are designed with large ramps like 1 3/8″ Bevels.

0Top-Level Thickness Requirements

Thresholds that are 5/8″ Thick on the top level (4″ and wider thresholds), either a Standard Bevel Design or a Hollywood Bevel Design, after the bevel the thickness chamfers down to 3/8″ Thickness. The part that is raised off the floor is only 1/4″ and does comply with ADA.

Thresholds that are 1/2″ Thick on the top level (2″ thresholds – only available in Standard Bevel Design), after the 1/4″ bevel, the thickness chamfers down to 1/4″ Thickness. The part that is raised off the floor is only 1/4″ and does comply with ADA.

Thresholds that are 3/8″ Thick on the top level ( 2″ thresholds – only available in Standard Bevel Design), after the 1/4″ bevel, the thickness chamfers down to 1/8″ Thickness. The part that is raised off the floor is only 1/4″ and does comply with ADA.

Concerns About ADA Door Threshold Requirements For Existing Or Altered Thresholds?

Is your project specified with 3/4″ Thresholds. Are you concerned our 5/8″ thick thresholds will not work? Fortunately, our teams have anticipated this potential setback. We have the solutions.

Some projects are specified with 3/4″ thick marble thresholds by Architects. Architects assume the threshold to be custom cut from slabs locally which are already 3/4″. Usually slimmer the better, however, if they were to specify 1/2″ or 5/8″, it would be impossible to make them locally. 

Our thresholds are made overseas and directly cut into the 5/8″  or 1/2″ thickness and work just fine within ADA regulations. If some more thickness is required for some special cases, this is also resolved by raising the threshold by adding more mortar beds.

The problem usually happens if a threshold is thicker than 3/4″ as ADA does not allow a threshold thicker than 3/4″. However, anything less is never an issue and will be approved with no problem.
