Which of the following activities might necessitate a special permit in Michigan?

The installation of complex systems or handling hazardous materials often requires a special permit in Michigan due to the significant safety and regulatory implications involved. These activities typically deal with complicated components, such as advanced HVAC systems that may incorporate specialized technologies or require compliance with local, state, and federal regulations regarding safety and environmental standards.

For instance, if a project involves a complicated HVAC installation that utilizes refrigerants or other hazardous substances, regulatory bodies may require permits to ensure that the work meets all safety codes and environmental protections. This serves to protect not only the workers on the project but also the public and the surrounding environment from potential hazards. The permits might include specific guidelines for the use and disposal of materials, necessary inspections, and adherence to local building codes.

In contrast, basic maintenance and routine inspections of HVAC systems, along with tasks like replacing air filters, typically do not necessitate special permits since these activities are generally considered standard practice within the industry and do not pose a significant risk to safety or compliance.
