Michigan Residential Builders License Practice Test

What is the maximum length allowed for a job-built ladder?

1. 20 feet

2. 24 feet

3. 30 feet

4. 32 feet

The correct answer is: 24 feet

The maximum length allowed for a job-built ladder is 24 feet. This limit is established to ensure safety and structural integrity when using ladders in various construction environments. Job-built ladders, which are often constructed on-site or customized for specific tasks, must adhere to guidelines that prioritize the stability and strength of the ladder under load conditions. A length of 24 feet strikes a balance between providing adequate reach for most residential building tasks while minimizing the risks related to height, such as falls and instability. Beyond this length, increasing concerns about structural strength, weight, and the ability of a single person to safely manage the ladder become prominent. Additionally, job-built ladders must comply with safety standards that are regulated by relevant building codes and occupational safety guidelines, which further reinforce this maximum length requirement.
