What ongoing duty do contractors have when building a new single-family residence?

The ongoing duty that contractors have when building a new single-family residence is to prevent wood-destroying pests or organisms. This responsibility is crucial as it directly impacts the structural integrity and longevity of the home. Wood-destroying pests, such as termites and carpenter ants, can cause significant damage if not properly mitigated during construction. Therefore, contractors are required to take preventive measures, which may include using treated wood, creating proper drainage systems, and providing barriers to pest entry.

While maintaining open communication with the client and providing warranties for workmanship are important aspects of a contractor's role, they do not specifically address the ongoing concern for the physical structure's protection against pests. Similarly, sourcing materials locally is beneficial for various reasons, but it does not align with the primary responsibility of safeguarding the home from biological threats. Thus, the focus on pest prevention is a core duty that ensures the health and safety of the residence being constructed.
