Which option lists the HUD disturbance threshold accurately?

• A. 2 ft2 Interior / 2 ft2 Exterior
• B. 6 ft2 Interior / 20 ft2 Exterior
• C. 12 ft2 Interior / 12 ft2 Exterior
• D. 4 ft2 Interior / 4 ft2 Exterior

Answer: (A)

Disturbance threshold refers to the amount of lead-based paint that, if disturbed during work, triggers the requirement for lead-safe work practices and containment under HUD rules. The standard threshold used here is 2 square feet for interior disturbances and 2 square feet for exterior disturbances. This small, uniform limit is designed to keep dust and lead exposure under control during renovations, regardless of whether the work is done inside or outside. So, when more than 2 ft² of lead-painted surface is disturbed inside or outside, you’re expected to implement lead-safe practices, contain the work area, and perform proper cleanup. The other figures listed don’t align with HUD’s commonly cited disturbance threshold for typical renovations, which is why the 2 ft² interior / 2 ft² exterior option is the best answer.
