FAQ – Access Ramps for People with Disabilities

Why install an access ramp for people with disabilities? 

An access ramp makes a location accessible to people in wheelchairs by helping them navigate steps or thresholds. Placed against or over the obstacle, it transforms it into a gentle slope that is easy to traverse. It benefits not only wheelchair and mobility scooter users but also seniors with walkers and parents with strollers. These devices are primarily installed in public buildings or multi-unit buildings, as private residences rarely have this type of access barrier at the entrance.

In accordance with the law of February 11, 2005 (Law 2005-102), public access buildings (ERP) must be accessible to all people with disabilities, whether physical, sensory, mental, cognitive, or psychological. The goal is to ensure that everyone has the opportunity to fully participate in social life.

Installing an access ramp not only fulfills a legal obligation and addresses a societal need, but also allows a broader audience to benefit from your services, with the potential to grow your business.

What width should be provided for a wheelchair access ramp? 

For an existing public building, the minimum width of a wheelchair access ramp must be 1.20 m. This dimension not only allows a wheelchair to pass through but also provides ample room for maneuvering, particularly in conjunction with doors that are often 80 cm wide. 

However, for a new building or one under construction, regulations require a greater minimum width, set at 1.40 m, to ensure optimal comfort of use and better traffic flow. 

What slope should be used for a PRM access ramp? 

In residential settings, there are no strict regulations. However, it is recommended to follow the standards applicable to public access buildings (ERP): 

• For a ramp less than 50 cm: maximum slope of 12%  
• For a ramp between 50 cm and 2 m: maximum slope of 8%  
• For a ramp longer than 2 m: maximum slope of 5%  

These guidelines help ensure a more comfortable and safe experience. 

How do you calculate the dimensions of an accessible ramp?

To determine the required length, use the following formula:

Ramp length (in cm) = height to be overcome (in cm) ÷ maximum slope × 100

Conversely, to calculate the slope from a given length:

Slope (%) = height to be overcome (in cm) ÷ ramp length (in cm) × 100

These calculations allow the ramp to be adapted to the site’s constraints while ensuring comfortable and safe use.

What are the accessibility regulations?

In a professional context, all public-access facilities must comply with technical accessibility standards to allow people with disabilities to enter and move around the premises easily. When there is a level difference, the installation of an accessible ramp becomes mandatory. This ramp must connect the street to the facility’s entrance to ensure smooth and safe passage.
