What are common indicators of poor housing sanitation?

Common indicators of poor housing sanitation often revolve around the physical conditions and maintenance of the living environment. Poor plumbing can lead to sanitation issues, such as leaks or sewage backups, which compromise hygiene and can contribute to the spread of disease. Additionally, pest infestations are a significant concern as they can be a direct consequence of unsanitary conditions, such as the presence of food waste or stagnant water. These factors not only show a lack of general maintenance but also present direct health risks to inhabitants.

In contrast, high energy efficiency ratings and well-maintained gardens suggest a level of care and investment in the property, indicating that the housing conditions are likely better. Similarly, accessible transportation services do not pertain directly to sanitation but rather relate to convenience and mobility, making it less relevant in assessing the sanitation standards of a housing space. Therefore, poor plumbing and pest infestations are telling signs of inadequate sanitation practices and housing conditions, making this selection the most accurate representation of the question.
