Which of the following options is NOT considered a code issue?

In the context of building codes, the focus is primarily on safety, structural integrity, and compliance with local and state regulations. Foundation slope, depth of footings, and insulation requirements all pertain directly to the structural and safety aspects of construction, thereby categorizing them as code issues that must be adhered to in order to meet safety standards and ensure that buildings are structurally sound.

Foundation slope is vital for water drainage management, which prevents issues such as flooding or water accumulation that can compromise a building’s foundation. The depth of footings is critical to ensure that the structure is adequately supported and able to withstand various loads, while insulation requirements are necessary for energy efficiency and comfort within buildings.

On the other hand, the color of a house, such as a purple house, does not relate to structural safety, building performance, or code compliance. Color choice is an aesthetic decision made by the homeowner and does not fall under regulatory codes. Therefore, a purple house is not considered a code issue.
