Plumbing Inspections

Certified plumbing inspectors ensure the safety of our water supply. Hamilton County Public Health inspects backflow devices, water heaters, and new and remodeled plumbing installations. When complaints about incorrectly installed plumbing or permit compliance arise, inspectors investigate and work to remedy problems. View Plumbing Fees here. The validation period for plumbing permits have been extended. View our Plumbing Regulation here.

All plumbing permit holders should review this NOTICE TO PERMIT HOLDER
