According to Georgia building codes, what is the maximum riser height for stairs in residential construction?
Correct Answer
A) 7.75 inches
Georgia building code limits stair risers to a maximum height of 7.75 inches in residential construction.
Why This Is the Correct Answer
Georgia's residential building code sets the maximum stair riser height at 7.75 inches. This measurement balances safety and comfort — risers higher than 7.75 inches increase the risk of tripping and falls. The Georgia code aligns with the International Residential Code (IRC) standard for this measurement.
Why the Other Options Are Wrong
Option B: 8 inches
Eight inches exceeds the maximum allowed riser height under Georgia's residential code. While 8 inches might seem close, even a quarter-inch over the limit is a code violation. Inspectors will measure and flag risers above 7.75 inches.
Option C: 8.25 inches
8.25 inches significantly exceeds the Georgia maximum riser height of 7.75 inches and would represent a clear code violation in residential stair construction. This option is likely included as a distractor to test whether candidates know the precise measurement.
Option D: 7.5 inches
7.5 inches is a valid riser height (it is below the maximum) but it is not the maximum — it is simply a compliant height. The question asks for the maximum, which is 7.75 inches, not 7.5 inches.
Memory Technique
Remember '7 and three-quarters' — like the platform at Harry Potter's 9 and 3/4, stairs in Georgia have their own 'three-quarter' rule: 7 and 3/4 inches maximum. Visualize a ruler stopped at the 7.75-inch mark with a red 'MAX' label.
