Plumbing Permit in Moore, OK — Cost, Requirements & Process
A plumbing permit is required in Moore any time a licensed plumbing contractor alters, extends, or replaces piping within the drain-waste-vent (DWV) system, the potable water supply, the gas system, or a water heater. Moore enforces the 2018 International Plumbing Code as adopted by Chapter 6 of the Code of Ordinances, and inspections are conducted by Community Development.
The permit is separate from the building and mechanical permits on the same project. A kitchen remodel that relocates a sink, for example, requires its own plumbing permit in addition to any building and electrical permits. Water heater replacements — including like-for-like swaps — require a plumbing permit in Moore, which catches many homeowners and handymen off guard.
Inspection is a two-stage process: a rough-in inspection while walls are open, and a final after fixtures and trim are set. A missed rough-in inspection almost guarantees a drywall tear-out, which is why the plumbing permit and inspection sequence drives the critical path on most remodel schedules in Moore.

Plumbing permit FAQs — Moore, OK
Do I need a permit to replace a water heater in Moore?
Yes. Even like-for-like water heater swap requires a Moore plumbing permit ($40 flat). Inspectors verify the T&P relief valve and discharge pipe, the seismic strapping (if gas), the gas connection (if gas), the cold-water shut-off, and the drain pan and overflow line.
Can I do my own plumbing in my Moore house?
Yes, on owner-occupied single-family property. The inspection standard is the same as licensed-contractor work — there is no leniency. Sign the homeowner affidavit at City Hall.
How long does a plumbing inspection take to schedule in Moore?
Same-day if requested by 7am via the GovBuilt portal or by calling (405) 793-5053. Otherwise next business day.
