Which of the following indicates visually identifiable mold during an inspection?

Discoloration and musty odors are key indicators of visually identifiable mold during an inspection. Mold often manifests as patches of color on surfaces, including walls, ceilings, and other materials. This discoloration can vary from green, black, or even white, depending on the type of mold present. Additionally, a musty odor is a common sign of mold growth, as it is a byproduct of the microbial activity. The coexistence of visual signs of mold and the associated odor strongly suggests active mold presence, guiding the inspector to further investigation and remediation if necessary.

In contrast, brightly colored wall paint does not indicate mold presence, but rather a surface finish. Cracked walls might suggest structural issues that could lead to moisture intrusion but are not direct indicators of mold themselves. Dust accumulation, while a common occurrence in many indoor environments, is not indicative of mold; it pertains more to general cleanliness and air quality. Thus, discoloration and musty odors serve as the most direct indicators of mold during an inspection.
