Do I need a permit for plumbing fixture or repiping in Dayton?

Permit required

Yes. In Ohio, plumbing fixture or repiping generally requires a permit, and Dayton is no exception.

Repiping a home is plumbing work that requires a permit under the Residential Code of Ohio and is not covered by the minor-repair exemption regardless of cost. If walls are opened and re-closed, the framing patch and insulation may need to be inspected before cover; confirm the inspection sequence with your local department. Dayton issues a separate plumbing permit through the Division of Building Inspection, so a whole-house repipe must be permitted even without structural work; confirm the scope at 937-333-3883. Rough-in must be inspected before covering walls, and closing walls before the inspection commonly forces removal to expose the work. Plumbing contractors must register and post a bond with the City before a permit is issued, and should hold the correct Ohio Construction Industry Licensing Board (OCILB) license, though an owner-occupant of a single-family home may do their own permitted work.
