In a target home, does the 2 square foot lead-based paint de minimus threshold apply per room or for the entire unit?

• A. Per room
• B. Cumulative for entire unit
• C. Per exterior surface
• D. Per window

Answer: (A)

Hazard assessment in NSPIRE is done room by room, so the 2 square foot de minimus threshold is applied to each room individually. This means you tally the lead-based paint area within a single room and compare it to 2 square feet. If that room has more than 2 square feet of lead-based paint on its surfaces, it’s considered a lead hazard in that room. If every room stays at or below 2 square feet, each room’s condition is de minimis, even if other rooms have different amounts. The threshold isn’t applied to the entire unit as a whole, nor to exterior surfaces or windows.
