Trade-off incentives permit increases in which building characteristics in exchange for sprinkler installation?

• A. Height, area, and number of stories
• B. Number of exits only
• C. Occupancy type changes
• D. Fire resistance rating adjustments

Answer: (A)

Trade-off incentives in building codes are designed to reward the installation of automatic sprinklers by allowing larger or taller buildings than would otherwise be permitted. When a sprinkler system is provided, the code may relax limits on the building’s size and vertical extent, enabling increases in the overall floor area, building height, and the number of stories. This is the practical motivation: sprinklers reduce fire risk, so designers can justify larger, more complex structures without compromising safety.

The other elements—exits, occupancy type changes, or fire resistance ratings—aren’t the typical concessions granted in exchange for sprinkler installation. Those aspects are governed by separate rules and trade-offs and aren’t the standard incentive linked to sprinkler presence.
