Summary

Norwalk does not issue a separate building permit for plumbing work done on its own; instead the Building Inspector charges a fee for every fixture or receptacle that drains into the system. Sewer connections are different: they always need a permit and fee, and crews cannot backfill the trench until the Building Inspector signs off.

A. Plumbing. (1) For plumbing work there is no building permit; a fee shall be charged for each fixture or receptacle intended to receive and discharge water, liquid or water-carried wastes into a drainage system with which they are connected. ... (3) Sewer connections. All connections to the City sewer system, including repairs to any existing private line now connected to said-City sewer, shall require a permit and payment of a fee therefor from the Building Inspector. No such connections or repairs shall be backfilled or concealed until approved by the Building Inspector or his assistants.

Full Breakdown

City Code Chapter 26 splits plumbing regulation into two tracks. Under § 26-7A(1), plumbing work performed independently, not bundled into a building permit for new construction, gets no separate building permit document; the Building Inspector instead bills a fee for each fixture or receptacle intended to receive and discharge water, liquid or water-carried waste into the drainage system. When plumbing is part of a larger construction, demolition or moving job, § 26-6A folds the plumbing fee into the single building permit fee paid before work starts.

Sewer work is treated more strictly: § 26-7A(3) requires a permit and fee from the Building Inspector for every connection to the City sewer system, including repairs to an existing private line already tied into it, and bars backfilling or concealing the trench until the Building Inspector or an assistant has approved it. Faulty workmanship or nonconforming materials trigger a reinspection under § 26-7A(2), but only after the owner or agent files a written reinspection request and pays the fee. Fee amounts themselves are not fixed in the ordinance text; § 26-8 assigns the Board of Building Fee Review, sitting with the Board of Building Appeals, to set, alter or eliminate fees with the Common Council's concurrence after a public hearing noticed 7 to 14 days in advance in a local newspaper.

The Council then has 90 days from the City Clerk's receipt of the Board's action to act on the schedule; silence for 90 days means the fees are deemed approved.

Violations & Fines

Starting any permitted work, including a sewer connection, before the required permit and fee are in hand exposes the owner to an investigation fee under § 26-6B equal to the building permit fee, with a $200 minimum, assessed whether or not a permit is later issued; the Building Official may waive it only for extenuating circumstances. Backfilling a sewer connection before Building Inspector approval violates § 26-7A(3) outright.

Frequently Asked Questions

Do I need a building permit for plumbing work in Norwalk?
Not a separate one if the plumbing job stands alone: § 26-7A(1) charges a fee per fixture or receptacle instead of issuing a building permit. If the plumbing is part of new construction, demolition or moving, its fee is folded into that project's single building permit under § 26-6A.
Do I need a permit to connect to the Norwalk sewer system?
Yes. Section 26-7A(3) requires a permit and fee from the Building Inspector for any connection to the City sewer system, including repairs to an existing private line, and the trench cannot be backfilled or concealed until the Inspector approves it.
What if I start plumbing or sewer work without paying the required fee first?
Section 26-6B lets the Building Official assess an investigation fee equal to the permit fee, at least $200, regardless of whether a permit is issued afterward. The fee can only be waived by the Building Official for extenuating circumstances.
Who decides what Norwalk charges for plumbing permits and fees?
The Board of Building Fee Review, made up of the Board of Building Appeals members, sets fees with Common Council concurrence after a public hearing under § 26-8. The Council then has 90 days to act before the schedule is deemed approved automatically.
