Final answer:
A variance from the health department is needed for building a new hospital, opening a restaurant, and starting a daycare, but not necessarily for renovating a school unless it involves health code aspects.
Step-by-step explanation:
A variance from the health department is usually required for activities or constructions that have the potential to affect public health, such as building a new hospital, opening a restaurant, or starting a daycare. These entities may need to obtain permission or a variance in order to ensure compliance with local health regulations, which can vary depending on the jurisdiction. However, renovating a school does not specifically require a variance from the health department, unless it involves changes that would affect health codes or regulations, such as the cafeteria or clinic areas.
Different organizations, whether they be a nonprofit health organization, a private hospital, or a governmental agency like Health and Social Services, must follow local health codes and may be required to seek variances for certain projects that fall outside of standard regulations.
