What can lead to the denial of a certificate of reoccupancy?

The denial of a certificate of reoccupancy often arises from the presence of hazards in a unit, even if the unit appears to be visually clean. Visual cleanliness does not guarantee that there are no underlying lead hazards, such as lead dust or deteriorated lead-based paint that may pose risks to occupants, especially young children and pregnant women. Lead can remain a significant health concern, and any identified hazards must be addressed before a unit can be deemed safe for reoccupation.

In contrast, a unit's aesthetic appeal (the first choice) does not influence reoccupancy if it contains lead hazards. Additionally, the absence of moderate or high risk work (the third choice) does not necessarily indicate a safe environment, as there could still be lead-related concerns. Completing demolition work (the fourth choice) also does not guarantee safety if proper lead abatement measures are not taken post-demolition. The presence of any lead hazards must be resolved to ensure the safety of future occupants, which makes the second choice the most accurate in the context of reoccupancy certification denial.
