What a plumbing permit costs in Ohio

3 Ohio jurisdictions we cover publish a fee figure for this work. Each line is quoted from that office's own schedule and linked to its citation. The figures are not comparable to one another: some are flat minimums, some a percentage of job value, some charged per fixture, so what you pay depends on which schedule applies and on your job's valuation.

Cincinnati

Fee Schedule effective July 1, 2026, "PLUMBING FEES" table: $68.00 to replace one fixture and $97.00 for one new fixture, with a per-fixture scale above that, plus the 5% planning surcharge and the 3% technology, 1% training and 1% financial recovery surcharges. The $49.00 RCO permit processing fee does not apply to plumbing repair or replacement applications that do not require plans.
