Under HUD's LSHR, exterior visual inspection is required when which condition occurs?

• A. Exterior painted surfaces were disturbed by renovation activity
• B. Exterior openings sealed during interior work
• C. Interior dust levels exceed thresholds
• D. The interior has less than four rooms

Answer: (C)

In HUD’s Lead Safe Housing Rule, dust-lead testing inside a unit helps determine if there are lead hazards that need remediation. When interior dust levels exceed the established action thresholds, a visual inspection of the exterior is required. This step ensures that potential lead hazards outside are not overlooked—excess interior dust can indicate deterioration or contamination that may also be present on exterior surfaces, and the exterior check helps identify any outside conditions (like deteriorated paint on exterior surfaces) that could contribute to exposure or require treatment.

The other scenarios don’t directly trigger the exterior visual inspection: disturbing exterior paint during renovation would call for containment and precautions, sealing exterior openings during interior work isn’t the specific trigger for an exterior visual check, and the number of rooms inside has no bearing on the requirement.
