This page is education, not legal advice. Permit rules, fees and inspection steps change, and they differ from one city to the next. Before you act on anything here, confirm the current requirements with your local building department. We re-review this page whenever the City of Columbus changes a plumbing, water-service or excavation rule that affects the work we do; the date above is when it was last checked.
Definition
What a Plumbing or Excavation Permit Is
A permit is written authorization from the local authority to do regulated work — replacing a water heater, a sewer lateral, a water service line, or gas piping, for example. It does two things: it puts the job on record, and it triggers an inspection, where the authority checks that the finished work meets the adopted plumbing and building codes before it is covered up or put into service.
In Columbus, plumbing permits go through the City of Columbus Department of Building and Zoning Services (see the city's building permit page). Water service lines also fall under City of Columbus Water & Power rules. Work in a public street or sidewalk typically needs a separate right-of-way permit.
When it applies
Work That Usually Needs a Permit
The general principle: if the job changes the plumbing system — new lines, new equipment, gas, anything buried — assume it is permitted work and ask. Routine drain cleaning, cabling and camera inspections are service work rather than construction; whether any permit applies is a question for the building department, and we will tell you what we know for your job.

Replacing a water service line
The buried line from the curb stop to the house. In Columbus this is also where the lead and galvanized rule below applies.
Main water line replacement -
Replacing or repairing a sewer lateral
Open-trench replacement, a spot repair, or a trenchless method — work on the line to the public sewer is regulated work.
Sewer line replacement -
Water heater replacement
A new tank or tankless unit involves gas or electrical connections and venting, so expect permit and inspection questions — ask us which apply to your replacement.
Water heater repair and replacement -
Gas piping
Repair, replacement or extension of gas lines, and the pressure test that goes with it.
Gas line repair and testing -
Repiping and new fixtures
Replacing supply or drain piping through a home, or adding plumbing where there was none.
Whole-home repiping -
Excavation in the right-of-way
Digging in a street, sidewalk or tree lawn to reach a line usually needs its own permit on top of the plumbing permit.

The Lead and Galvanized Service-Line Rule
What the city says
As DrainMaster understands the current City of Columbus Water & Power rules, repair of lead and galvanized water service lines is prohibited. Those service lines must be fully replaced with compliant material.
In practice, this means a galvanized or lead service line cannot simply receive a normal spot repair. If your line breaks and it turns out to be galvanized or lead, the job becomes a full replacement — which is why the material of your service line is one of the first things we check on a water-line call, and why it matters for the water-line spot repair and water-line replacement cost guides.
The water service line is split into a city-owned section and a property-owner section. The city publishes its own program information on lead and galvanized service lines; read it at Columbus Water & Power's lead service line program page. If you are not sure what your line is made of, our galvanized water line replacement page covers what that replacement involves.
Other cities we serve — Hilliard, Dublin, Grove City, Westerville and the rest of the communities we serve — each have their own building department and their own rules. We have not published per-city specifics here because we will not guess at them; ask us about your address and we will tell you which authority applies.
Failure modes
What Happens If Work Isn't Permitted
The risk categories, in plain terms. The specifics — penalties, fees, what an inspector asks for — depend on the jurisdiction and the job.
-
A failed or missing inspection
Permitted work is inspected before it is closed out. Unpermitted work has no inspection record, and a later inspection can require it to be opened up or redone.
-
Problems at resale
Buyers, appraisers and title work can surface unpermitted plumbing or sewer work, and the seller is usually the one who has to resolve it.
-
Insurance questions
If unpermitted work is involved in a loss, the claim can be harder to settle. This varies by policy — ask your carrier, not us.
-
Redo costs
The most expensive permit is the one pulled after the fact, because it can mean exposing finished work to inspect it.
