According to the Florida Building Code, what is the maximum allowable slope for an accessible ramp?
Correct Answer
C) 1:12 (8.33%)
The Florida Building Code follows ADA guidelines requiring accessible ramps to have a maximum slope of 1:12 (8.33%). This ensures wheelchair accessibility and safety.
Why This Is the Correct Answer
The Florida Building Code adopts the Americans with Disabilities Act (ADA) accessibility standards, which specify a maximum slope of 1:12 (8.33%) for accessible ramps. This ratio means for every 12 inches of horizontal run, the ramp can rise no more than 1 inch vertically. This slope provides the optimal balance between accessibility for wheelchair users and practical construction requirements. Steeper slopes would be unsafe and difficult for wheelchair users to navigate independently.
Why the Other Options Are Wrong
Option A: 1:8 (12.5%)
A 1:8 slope (12.5%) is significantly too steep and would violate accessibility codes, creating a dangerous condition for wheelchair users.
Option D: 1:6 (16.67%)
A 1:10 slope (10%) is too steep and exceeds ADA requirements, making it unsafe and non-compliant for wheelchair accessibility.
Memory Technique
Remember '1-12 ADA' - the ratio sounds like a date (1/12) and ADA ensures accessibility for all.
Reference Hint
