A roofing crew is performing a tear-off on a residential roof in California. The roof has an area of 2,000 square feet. According to Cal/OSHA regulations, what is the minimum required width for a roof access ladder landing area if the ladder provides access to the roof from the ground?
- A24 inches
- B30 inches
- C12 inches
- D18 inches
Show answer & explanationAnswer & explanation
Correct answer: D. 18 inches
Cal/OSHA requires that a landing area at the top of a ladder be at least 18 inches in width and 24 inches in length. This ensures safe transition on and off the ladder.
Why the other options are wrong
- A. 24 inches is the minimum required length, not width, for a ladder landing area.
- B. 30 inches exceeds the minimum requirement, but 18 inches is the correct minimum width.
- C. 12 inches is too narrow for a safe landing area according to Cal/OSHA.
Cal/OSHA Ladder Landing Width
The minimum width required for a landing area at the top of a fixed or portable ladder used for roof access.

Memory trick: Eighteen inches wide, like a small stepping stone, keeps you safe when on the roof you roam.
