What is the maximum height for a double block pier?

30 inches
32 inches
36 inches
40 inches

The correct answer is: 36 inches

The maximum height for a double block pier being set at 36 inches is based on structural integrity and building codes that emphasize safety and stability in construction practices. Piers serve as foundational supports and their height must be regulated to prevent issues such as instability, excessive sway, and the potential for failure under load. Specifically, a height of 36 inches allows for sufficient support while maintaining the necessary strength and stability needed for residential foundations. Taller piers may introduce complications such as increased lateral forces and potential settlement issues, which can undermine the structural integrity of the building they support. By regulating the height, building codes ensure that construction practices yield safe and durable structures. Therefore, 36 inches is recognized as a reliable height limit that balances safety, structural performance, and practical considerations in home inspection and construction.
