OSHA Stair Rise Requirements: Essential Guidelines

By Jessica GarciaJanuary 2, 2026

Stair safety is a critical aspect of workplace design, and the Occupational Safety and Health Administration (OSHA) has established clear guidelines to ensure safe stairway usage. One of the key requirements is the stair rise, which significantly impacts the safety and comfort of users. Let's delve into OSHA's stair rise requirements and their importance in maintaining a safe work environment.

OSHA's stair rise requirements are outlined in 29 CFR 1910.22, which covers general industry requirements for stairways and stairway systems. The stair rise, also known as the riser height, is the vertical distance between two adjacent treads. Understanding and adhering to these requirements is essential for employers to provide a safe workplace for their employees.

OSHA's Stair Rise Requirements

OSHA has set specific criteria for stair rise to ensure safe and comfortable usage. These requirements apply to all stairways with four or more risers or rising 30 inches or more.

Understanding these requirements is crucial for employers to ensure their stairways comply with OSHA standards and provide a safe working environment for their employees.

Maximum Stair Rise

OSHA has established a maximum stair rise of 9.5 inches (241 mm). This limit is designed to prevent users from having to lift their feet too high, which could lead to trips, falls, or fatigue.

Exceeding this limit can result in increased physical exertion, leading to potential safety hazards. Therefore, it's essential to maintain stair rises within this maximum limit to ensure user safety and comfort.

Minimum Stair Rise

While there is no minimum stair rise requirement in OSHA's regulations, it's crucial to consider practical aspects when designing stairways. A stair rise that is too low can also pose safety risks, as users may stumble or trip due to the shallow step.

To ensure safety and comfort, many building codes and industry best practices recommend a minimum stair rise of 4 inches (102 mm). This range provides a comfortable and safe step height for most users.

Importance of Adhering to OSHA's Stair Rise Requirements

Adhering to OSHA's stair rise requirements is not just about compliance; it's about ensuring the safety and well-being of employees. Properly designed stairways can significantly reduce the risk of falls, trips, and other stair-related injuries.

Moreover, maintaining stairways in accordance with OSHA's guidelines can help prevent long-term health issues, such as musculoskeletal disorders, that may arise from using poorly designed stairways over extended periods.

Stair Rise and Slip Resistance

While OSHA's regulations focus on stair rise, it's essential to consider other factors that contribute to stair safety, such as slip resistance. Stair treads must have a slip-resistant surface to prevent falls due to slipping.

OSHA's general industry regulations (29 CFR 1910.22) require that stair treads have a slip-resistant surface. This requirement is crucial for maintaining safe stairways, as slippery surfaces can significantly increase the risk of falls.

Stair Rise and Tread Depth

In addition to stair rise, OSHA also sets requirements for stair tread depth. The tread depth, or the horizontal distance between the vertical nosings of adjacent treads, must be at least 9.5 inches (241 mm).

This requirement ensures that users have enough space to place their feet comfortably on each step, further enhancing safety and comfort.

In conclusion, understanding and adhering to OSHA's stair rise requirements is vital for employers to provide a safe working environment. By maintaining stairways that comply with these regulations, employers can significantly reduce the risk of stair-related injuries and create a more comfortable and safe workplace for their employees. Regular inspections and maintenance of stairways are essential to ensure ongoing compliance with OSHA's standards. If you're unsure about your stairway's compliance, consider consulting with a safety professional to ensure your workplace meets all necessary requirements.
