When might the Butlers be liable for the acts of their independent contractor?

The Butlers could be liable for the acts of their independent contractor primarily if they provided blueprints that significantly dictate how the work should be performed. This principle is rooted in the concept of control; when a property owner provides detailed plans or specifications, it may be interpreted that they are exerting a level of control over how the work is carried out. This can create a scenario where the property owner assumes some liability for the contractor's actions because they essentially directed and influenced the execution of the work.

In contrast, if the contractor is unlicensed, the liability may not necessarily fall on the Butlers unless there are other factors at play, such as negligent hiring. Regarding a hazardous worksite, this does not automatically transfer liability to the Butlers unless they contributed to the danger or failed to take necessary precautions. Similarly, simply being present on site during renovations does not establish liability for the independent contractor’s actions unless it can be shown that they influenced the contractor's methods or the safety of the work. Thus, the provision of blueprints illustrates a direct association with the work performed, making it the most relevant choice for liability concerns.
