Our job is to help create healthy environments in which people can live, work and play. A health hazard is anything in the condition of a building or property; material (solid, liquid or gas); or plant or animal that could make people sick or unsafe.
Public Health works to reduce health risks from air, water, food, housing, climate, and the built environment.
- We inspect, monitor, investigate, and educate to prevent illness and injury.
- We respond to complaints and emergencies, and enforce health regulations.
- We work with community partners to create safer, healthier environments for everyone.
- Our work prioritizes prevention, equity, and clear information residents can use daily.
