What amount of mold like substance is considered a deficiency?

• A. Two square inches
• B. Six square inches
• C. Four square inches
• D. Eight square inches

Answer: (C)

Mold-like substance is treated as a deficiency when it reaches a measurable size that indicates a moisture problem and requires remediation. For this item, the threshold is four square inches. That means a mold-like spot that covers four square inches or more is considered a deficiency, while smaller areas do not meet the cutoff under this standard. To apply it, measure the area of any visible mold-like substance on interior surfaces (estimate for irregular shapes or sum multiple spots). If the total area is at least four square inches, it’s a deficiency. Larger spreads, like six or eight square inches, are also deficiencies, but the important point is the minimum size that triggers reporting: four square inches.
