According to Tennessee building codes, what is the minimum width required for emergency egress windows in residential bedrooms?
Correct Answer
C) 20 inches
Tennessee building codes require emergency egress windows in bedrooms to have a minimum width of 20 inches.
Why This Is the Correct Answer
The International Residential Code (IRC), adopted by Tennessee, requires emergency egress openings in sleeping rooms to have a minimum net clear opening width of 20 inches. This is a life-safety minimum — it allows a person to escape and a firefighter to enter.
Why the Other Options Are Wrong
Option A: 24 inches
24 inches exceeds the minimum width requirement. While a wider window provides more egress clearance, the code minimum is 20 inches, not 24.
Option B: 30 inches
30 inches is a common interior door width and a figure that appears in other building code contexts, but it significantly exceeds the egress window minimum width of 20 inches.
Option D: 22 inches
22 inches is close to but not the correct code minimum. The IRC specifies 20 inches exactly; 22 inches is not a recognized code threshold.
Memory Technique
Remember the egress window triad: Width = 20, Height = 24, Area = 5.7 sq ft. Width is always the smallest number. '20 wide to slide outside.'
