The Delaware Public Health District Plumbing Unit inspects new plumbing in residential, commercial buildings and medical gas installations in Delaware County except in the cities of Columbus, Dublin, and Westerville.

The plumbing inspectors assure the installation meets the State of Ohio Code requirements. These inspections also help to protect your health and your family’s health, assure the quality of the water you drink in your home, and protect the community water source, such as Del-Co Water Co. or Delaware City Water, from cross connections.

While enforcement comes to mind when you think of inspectors, our inspectors like to utilize education opportunities to help achieve compliance. Our inspectors perform consultations with plumbing contractors as well as homeowners to discuss issues that arise during a job. 

If you are submitting a plan review request(commercial only) or are requesting a permit, please be sure to include all of the below or your applications/inspection will be rejected.
