What type of buildings qualify as child-occupied facilities?

The correct answer is supported by the specific regulations set forth regarding lead exposure and its risk to children. Child-occupied facilities are defined as buildings that are frequented by children, particularly those under the age of six, and where there is a potential for lead exposure. This definition often includes places where children learn and play, but more specifically, it applies to buildings constructed before 1978. This is because that year marks the final ban on the use of lead-based paint; prior to this, many buildings still had such materials, placing children at risk.

The relevance of building age ties into the understanding that older structures may still harbor lead paint and lead-contaminated dust or soil, thereby increasing the importance of risk assessment and remediation in these environments. Facilities dedicated to daycare provide an even higher level of concern, as they serve children who are particularly vulnerable to lead's harmful effects.

In contrast, the other answer choices do not align with the established criteria. Buildings constructed after 1990 would not typically qualify because they are unlikely to contain lead-based materials. Any building where children visit regularly might indicate a potential for exposure, but it lacks the specificity required to classify it as a child-occupied facility without considering the construction date. Lastly, while daycare facilities
