What size crack in a foundation is considered a deficiency?

• A. 1/8 inch by 6 inches
• B. 1/2 inch by 24 inches
• C. 1/4 inch by 12 inches
• D. 3/8 inch by 10 inches

Answer: (C)

Foundation cracks are evaluated by size, and a deficiency is defined by a crack that reaches at least 1/4 inch in width and at least 12 inches in length. The crack that is 1/4 inch wide and 12 inches long meets both criteria exactly, so it qualifies as a deficiency. The other options fail to meet both dimensions at once—either they're too short or too narrow—so they do not meet the deficiency threshold.
