According to the IPMC, which of the following issues qualifies a structure as unfit for human occupancy?

A structure is deemed unfit for human occupancy when it poses health and safety risks to its occupants. The International Property Maintenance Code (IPMC) outlines specific conditions that can render a dwelling unsafe or uninhabitable. Each of the identified issues contributes to such a classification.

Lack of ventilation can lead to poor indoor air quality, contributing to harmful conditions such as excessive humidity that may promote mold growth or inadequate oxygen levels. This can severely affect the health of the occupants.

Vermin infestation presents another significant concern, as pests such as rats, mice, or insects can transmit diseases, contaminate food sources, and create unhygienic living conditions. The presence of vermin not only indicates neglect but also endangers the well-being of residents.

Filth within the structure can encompass unsanitary conditions, leading to a breeding ground for bacteria and other pathogens. Accumulated dirt and debris can pose not only a visual nuisance but also attract pests and contribute to health hazards.

Given that each of these conditions independently qualifies a structure as unfit for human occupancy, the best answer is that all three issues collectively contribute to the safety hazards associated with human habitation. Therefore, recognizing that a combination of these factors can create an uninhabitable environment is
