Plumbing Permit in Norman, OK - Cost, Requirements & Process
A plumbing permit from Norman Development Services is required for new plumbing rough-in, fixture additions, water heater replacements, sewer-line repair/replacement, gas-line work, and backflow prevention installation inside Norman city limits. Norman has adopted the 2018 IPC and enforces it through plumbing inspections in Click2Gov. The plumbing contractor of record must hold an active OCIB plumbing license.
Norman plumbing fees are flat: residential plumbing rough-in (new construction) $120; per-fixture $10; water heater replacement $55; sewer line repair $75; gas line addition or relocation $65 base + $5 per outlet; backflow prevention $40. Minimum permit fee is $55.
Lake Thunderbird watershed projects (most of east Norman) face stricter requirements for backwash discharge and any plumbing tied to pool equipment - direct discharge to a storm drain or surface water is prohibited under Norman Code Chapter 20 watershed protection.

Plumbing permit FAQs — Norman, OK
Do I need a permit to replace a water heater in Norman?
Yes. Water heater replacement is a flat $55 plumbing permit. You will also need to pass a final inspection verifying T&P relief discharge, expansion tank (closed system), gas connection (if gas), and anti-scald protection.
What about a fixture swap - new toilet for old toilet?
Like-for-like fixture replacement using existing supply and waste connections does NOT require a permit. Moving the fixture, adding a fixture, or rerouting any supply or drain DOES require a permit.
