Public Health - Dayton & Montgomery County

The purpose of the Plumbing Inspection Program is to ensure that all plumbing installed during construction of a new or renovated building is installed by knowledgeable craftsmen in accordance with applicable codes. Properly installed plumbing systems protect the public’s health by preventing bacterial or chemical contamination of the public water supply caused by accidental backflow as well as by preventing exposure to discharge from improperly installed wastewater drainage systems.

The plumbing program is responsible for on-premise sewer and water systems in many areas of the county.  This program provides oversight of the installation of plumbing systems in all areas of Montgomery County except for the Cities of Centerville, Dayton, Oakwood and Kettering. However, Public Health will continue to issue permits and provide oversight of on-premise sewer water and irrigation/deduct meter installations. Plumbing contractors and in limited cases, homeowners, may apply for permits to install plumbing systems in new or remodeled construction, with response to inspection requests normally within 24 hours. The Plumbing Inspection Program registers all persons engaged in the business of plumbing within the jurisdiction of Public Health.
