Step-by-step explanation:
In the context of housing and building codes, the term “installed” typically means an item that is fixed into position or connected in such a way that it requires tools to remove. This can include features such as built-in appliances, electrical fixtures, or plumbing components. When referring to building safety requirements within More Developed Countries (MDCs), standards of practice involve ensuring that homes are equipped with essential services and safety devices that are properly installed, which includes running water, working ventilation and heating systems, structural integrity, smoke detectors, and safe electrical wiring. These building codes are crucial as they are enforced to safeguard the well-being and safety of a home's inhabitants, despite the associated costs and frustrations that may come with compliance.
