Is the 2 square foot lead based paint de minimus requirement in a target home per room or cumulative for the entire unit?

• A. Cumulative for entire unit
• B. Per room
• C. Per exterior wall
• D. Per floor

Answer: (B)

The threshold is applied per room. In NSPIRE inspections, the 2 square feet de minimis amount of lead-based paint is evaluated for each individual room, not across the whole unit. That means a room with 2 square feet or more of LBP triggers the de minimis threshold for that space, regardless of how much LBP exists in other rooms. This per-room approach ensures localized issues are identified where they exist, rather than being averaged or summed across the entire unit. Evaluating by exterior wall or by floor would misrepresent how the issue is distributed within the interior living spaces.
