Home / Permits / Plumbing (moved or new lines)

Do you need a permit for a plumbing (moved or new lines)?

Yes. Moving or adding supply or drain lines is a permit item across the north suburbs, typically $75 to $300, and Illinois requires a licensed plumber for the work. Expect a rough plumbing inspection, a pressure test and a final. A like-for-like faucet or toilet swap at the existing connections is exempt.

Typical fee: $75-$300, scaled to project value in most villages.
