According to the 2020 Florida Building Code, what is the maximum slope allowed for an accessible ramp without requiring handrails?
Correct Answer
D) 1:20 (5%)
Per the Florida Building Code and ADA requirements, ramps with slopes steeper than 1:20 (5%) are considered ramps and require handrails. Slopes of 1:20 or less are considered sloped walkways and do not require handrails.
Why This Is the Correct Answer
Option C (1:20 or 5%) is correct because the Florida Building Code establishes this as the threshold between sloped walkways and ramps. Any slope steeper than 1:20 is classified as a ramp and requires handrails for safety. Slopes at 1:20 or less are considered sloped walkways and can be constructed without handrails, making this the maximum allowable slope for accessible paths without handrail requirements.
Why the Other Options Are Wrong
Option A: 1:12 (8.33%)
Option A (1:12 or 8.33%) is incorrect because this slope is steeper than the 1:20 threshold and would require handrails. While 1:12 is the maximum slope allowed for accessible ramps WITH handrails, it exceeds the limit for ramps without handrails.
Option C: 1:25 (4%)
Option D (1:25 or 4%) is incorrect because while this slope would not require handrails (being less steep than 1:20), it is not the maximum allowable slope. The question asks for the maximum slope without handrails, which is 1:20, not the more conservative 1:25.
Memory Technique
Remember '1:20 is the key' - slopes of 1:20 or less are 'walkways,' anything steeper becomes a 'ramp' requiring handrails. Think 'Twenty is plenty' for no handrails.
