If exterior openings were left unsealed during interior renovation, which inspection becomes required?

• A. Interior only visual inspection.
• B. Annual building inspection.
• C. Exterior visual inspection.
• D. No inspection is required.

Answer: (C)

When there’s a chance for contaminants to escape through openings to the outside, the inspection scope expands beyond the interior. Leaving exterior openings unsealed during interior renovation creates a pathway for lead dust or debris to migrate outside the structure. Because of that potential migration, you must evaluate the exterior environment to confirm there’s no contamination and that containment measures around those openings are effective. An exterior visual inspection specifically looks at exterior surfaces, the openings themselves, and surrounding areas to spot any signs of lead dust, damaged paint, or compromised sealing that could allow debris to spread. It also helps verify that cleanup and containment plans applied to the exterior are working as intended.

Interior-only visual checks won’t address the outside pathway, and other options like an annual building inspection or no inspection wouldn’t target the risk created by unsealed exterior openings.
