ADA Compliant Marble Door Thresholds

When you are building commercial projects, it’s important to keep in mind that you’re building a dwelling for the public. That means that everyone should have easy accessibility.

Regulations for Public Dwellings

The Americans with Disabilities Act (ADA) enforces regulations for public businesses to provide accommodations for people with disabilities. The ADA defines anyone with a disability as someone who has “a physical or mental impairment that substantially limits one or more major life activities, a person who has a history or record of such an impairment, or a person who is perceived by others as having such an impairment.” For iexample, you’ll find that every public facility has a parking space for handicapped parking. Restaurants have tables that are wheelchair accessible. And all public facilities must have wheelchair accessible restrooms, entrances, and doorways.

Responsibilities as a Builder

As a construction company if you want to avoid any costly settlements, then you must understand that it’s your responsibility to educate yourself on all of the building codes.

For instance, if you’re contracted to build a lot of residential homes, then you know that you’d have to go downtown and get a building permit, get a survey on the land so that you know exactly where your property ends and begins, where to dig and where you definitely should not. If you’re contracted for a commercial build, while the same responsibilities stand, other things have to be taken into processing because now you are dealing with the public. You have to build a dwelling that’s accessible for everyone, including those with disabilities. 

Make Sure Your Doorways Are ADA Compliant

One of the most important ways to ensure that your build is ADA compliant is making sure your doorways are wide enough for a wheelchair to pass through and that the threshold doesn’t serve as an obstacle. Standard thresholds that are less expensive like aluminum, wood, vinyl, and even metal are flat enough to provide easy access for a wheelchair to roll over, but if you’re considering installing marble thresholds, then you have to be more detail orientated about the type of threshold you’ll need to order. 

The Purpose of Marble Thresholds

When builders choose to install thresholds, they usually do if for the dual purpose of presenting an aesthetic appeal as well as a barrier from exterior weathering elements and even water. For public dwellings, this is a direct violation against ADA Compliancy. However, there is a way to have a decorative barrier while meeting ADA regulations. 

The Hollywood Threshold

Marble thresholds stand approximately 5/8” tall. That’s enough to provide a nice little halt to any rolling object. For wheelchairs, this might be challenging for some depending on the person’s strength, considering that they have to push their own weight as well as the weight of the chair.

So when you choose to install marble thresholds, it must be the kind with a Hollywood Bevel. There are two kinds of Hollywood Marble thresholds: Single Hollywood Bevel and Double Hollywood Bevel. Both to them come in a variety of sizes from 4” to 6” wide. The 4” thresholds are commonly used for hotels. These marble thresholds also come in a 5”-width selection.

Difference Between a Single and Hollywood Bevel

The Single Hollywood Bevel has a slight incline on one side of the threshold. That means that while it stands as high as 5/8”, the incline drops to a height of 3/8” providing a 1 3/8” slope. You’ll find that the Single Hollywood Bevel will serve your construction needs for front and back doors—access to and from the interior and exterior, or for unleveled floors.

The Double Hollywood Bevel provides a slight incline on both sides of the marble threshold. The measurements remain the same in regards to the slope of the incline—it’s just with the Double Hollywood Threshold, a rolling object like a wheelchair or bed has an easier time of transitioning from one room to the next.
