Multifamily units can have different sizes, floor plans, and number of bedrooms and still meet which criterion?

• A. Ownership must be identical.
• B. Exterior finish must be the same.
• C. All units must be on the same floor.
• D. Different sizes, floor plans, and number of bedrooms and still meet commonality.

Answer: (D)

Commonality in a multifamily project is about sharing building-wide features that define the risk and the approach across units, not about every unit being a perfect clone. Even if units vary in size, floor plan, or number of bedrooms, they can still meet commonality as long as they were built with the same construction materials, finishes, and environmental conditions relevant to the assessment or remediation. This means the same sampling strategy and treatment can apply across the units because the potential lead-based paint conditions are governed by the same building practices and materials, not by exact unit layout. Ownership status, different exterior finishes, or units lying on different floors aren’t required to affect commonality. The key is that the units share core building characteristics that determine how lead hazards are evaluated and managed.
