What regulation involves renovations in residential housing built before 1978?

The regulation that specifically addresses renovations in residential housing built before 1978 is focused on lead-based paint hazards, which is critical for the safety of occupants, particularly children, who are vulnerable to lead poisoning. This regulation requires contractors to follow specific guidelines when performing work that may disturb lead-based paints. This includes conducting risk assessments, notifying residents of potential hazards, and utilizing safe work practices to minimize lead exposure during renovations.

The other options do not directly relate to the requirements for handling lead-based paint in residential properties. For example, the Health Insurance Act pertains to health coverage and benefits rather than construction safety. Environmental Protection Regulations cover a broader range of environmental issues, while Employee Safety Standards focus on workplace safety rather than specific regulations concerning lead paint in homes. Hence, the focus on lead and its implications in homes built before 1978 makes this option the most appropriate choice.
