Which of the following is considered an "immediately hazardous" condition?

A structural collapse is considered an "immediately hazardous" condition because it poses a significant threat to safety and lives. When a structure begins to collapse, it can lead to severe injuries or fatalities for occupants, passersby, and responders. The urgency of addressing such a condition is paramount, as it represents a critical risk that requires immediate attention from code enforcement officials and emergency responders to mitigate harm.

In contrast, minor plumbing issues, unpainted exteriors, and inconvenient property lines, while potentially problematic, do not present an immediate danger to human life or safety. These issues may warrant corrective action but do not necessitate the immediate intervention that a structural collapse does. Thus, the classification of a condition as "immediately hazardous" is reserved for those that can result in imminent risk, making a structural collapse the clear example in this context.
