Does HUD require whole unit clearance?

• A. No, only the work area.
• B. Yes, but only for exterior units.
• C. Yes, generally.
• D. Only after a second visual inspection.

Answer: (C)

After lead-based paint work in a HUD-regulated unit, the final clearance typically covers the entire unit. This is because lead dust can migrate beyond the exact area where work was done, so checking only the work zone could miss contamination in other rooms, hallways, or common areas. Clearance testing of the whole unit ensures that the entire living space meets the established lead-dust and residue standards before anyone occupies it, protecting occupants—especially children—from exposure. While there may be rare exceptions if containment is perfect and the rest of the unit is proven clean, the standard practice is to clear the whole unit, so this is considered the general requirement.
