Standard access ramps are the most common type of ADA ramps. Typically used to provide wheelchair access to buildings or elevated surfaces. These ramps must adhere to strict ADA ramp specifications to ensure safety and usability.

Key features of standard access ramps:

Slope: Maximum 1:12 (8.33% or 4.8 degrees slope)
Width: Minimum 36 inches clear width
Length: Maximum run of 30 feet before a landing is required
Handrails: Required on both sides if the rise is greater than 6 inches

2. Modular Ramps

Modular ramps are versatile solutions that can be customized to fit various layouts and space constraints.

These ramps are often used in both permanent and temporary installations. Their characteristics are adjustable length and configuration and typically made of aluminum for durability.

The modular ramp must meet the same slope and width requirements as standard ramps. They often feature non-slip surfaces for added safety.

3. Threshold Ramps

Threshold ramps are small ramps used to bridge the gap between different floor levels, such as at doorways or slight elevation changes.

While they may be smaller, they still need to comply with ADA ramp safety requirements. Threshold ramps are typically used for rises of 6 inches or less. The slope requirements may vary based on the specific application.

They must have a non-slip surface and edge protection may be required depending on the design.

4. Portable Ramps

Portable ramps provide temporary accessibility solutions and are often used for events, temporary structures, or as interim solutions during construction.

They must meet the same slope and width requirements as permanent ramps and should have a stable, slip-resistant surface.

Portable ramps might require edge protection and handrails depending on the height. Their weight capacity should be clearly marked and appropriate for intended use.

Standard Ramps Vs. Curb Ramp: Understanding The Differences

When discussing ADA compliant ramp design, it’s important to distinguish between standard ramps and curb ramps.

While both fall under ADA ramp types and requirements, they serve different purposes and have distinct specifications.

Standard ramps are typically used for building entrances, elevated platforms, and other significant changes in elevation. Curb ramps, also known as curb cuts, are specifically designed to provide a smooth transition from a pedestrian walkway to a street level.

Standard Ramps	Curb Ramps
Longer runs with multiple sections and landings	Shorter and steeper than standard ramps
User for heights differences of more than 6 inches	Minimum width of 36 inches, excluding flared sides
Handrails on both sides	Do not require handrails due to their short length
Maximum slope of 1:12	Built with 1 1:10 slope for street-to-sidewalk
Transitions	Require detectable warning surfaces (truncated domes) at the bottom

Designing ADA Compliant Ramps

Designing ADA-compliant ramps requires careful attention to specific dimensions and proportions.

The design of ADA-compliant ramps involves a delicate balance between slope, length, width, and other factors that collectively contribute to their usability and safety.

Each dimension plays a crucial role in ensuring that individuals can navigate the ramp comfortably and independently. Let’s explore the specific requirements for standard ramp width, maximum rise, and length-to-rise ratio, which form the foundation of proper ramp design.

Maximum Ramp Rise: The vertical height the ramp can ascend before a landing is maximum 30 inches.
Length-to-Rise Ratio: This ratio determines the slope of the ramp. The maximum slope allowed for a ramp is 1:12, which means for every inch of rise, there must be at least 12 inches of ramp length.
Landing Requirements for ADA Ramps: Landings provide level resting areas and maneuvering spaces for wheelchair users and individuals with mobility aids. Ramp landings should be at least as wide as the ramp itself and a minimum of 60 inches long.

Slope Requirements For Wheelchair Access

The slope of a ramp is perhaps the most critical factor in ensuring its accessibility and safety for wheelchair users.

A properly designed slope allows individuals to ascend or descend the ramp with minimal effort and maximum control. It’s important to understand the nuances and best practices surrounding slope requirements. Factors that influence slope choice includes the length of the ramp, available space, and the weather conditions in the area.

Steepest allowable slope: 1:12 (8.33% or 4.8 degrees)
Recommended gentler slopes: 1:16 or 1:20

PRO TIP!

Always check for proper slope and width to ensure your ramps meet California’s ADA requirements for safety and accessibility.
