What is the typical maximum height of a single block pier?

16 inches
20 inches
24 inches
30 inches

The correct answer is: 20 inches

The typical maximum height of a single block pier is generally understood to be around 20 inches. This standard is primarily based on construction practices and structural engineering principles, which dictate that piers must be adequately supported while providing stability to the structure they support. Block piers are often used in foundation systems, particularly in crawl spaces. Beyond this height, additional engineering considerations and design adjustments become necessary to ensure the structural integrity of the building. Exceeding this height without proper reinforcement can compromise the load-bearing capabilities of the pier, leading to potential structural failures or shifts in the foundation over time. It is important for home inspectors to understand these specifications as they assess the foundation conditions during an inspection. Recognizing a pier that exceeds this typical height can signal the need for further evaluation to ensure it meets safety and structural guidelines.
