Usually nothing at all — on the day. That is the whole problem. No inspector drives past your house and notices a new water heater. The consequences of unpermitted plumbing arrive later, through other people: a buyer’s inspector, a lender, an insurance adjuster, or the next plumber who opens the wall.
This page is about what those consequences actually are in Texas, and what to do if the work is already done.
Texas hands cities five jobs they cannot be forced to permit:
If your job is on that list, the state did not require your city to make you pull a permit. That is not the same as a guarantee: a city may still require one for any of the five, so check yours before you conclude you were in the clear. If your job is not on the list — a water heater, a repipe, a sewer line, a gas line, or anything that moves or adds pipe — your city almost certainly required a permit, and our Texas permits guide sets out who may pull one where you live.
Austin publishes the plainest version of this, and it is worth reading as written rather than paraphrased.
The city gives homeowners three consequences:
Notice what is not on that list: a knock at the door. The city is not describing enforcement. It is describing the three places the absence of a record turns into money — the redo, the transaction, and the claim.
We are not going to quote you a fine. Many cities charge extra when work is done before a permit is obtained, and we have not been able to read a current published penalty schedule for any of the Texas cities on our list. Rather than repeat a figure from somewhere else, we say plainly that we do not have it. Your city’s building department will, in one phone call.
This is the part that makes plumbing different from most unpermitted work, and it is physical rather than legal.
Plumbing disappears. Pipe goes into a trench and the trench is backfilled; pipe goes into a wall and the wall is closed. The permit exists to put a city inspector in front of that work in the narrow window when it can still be seen. Lubbock’s tap process states the timing outright: the contractor schedules the inspection “at least two hours before backfill.”
Miss that window and nobody can verify the work without undoing it. Not you, not a buyer’s inspector, not the next plumber. That is why an unpermitted repipe is a permanently open question about your house, in a way that an unpermitted paint job never is.
Texas sellers give the buyer a written disclosure about the property’s condition, and it is a state-prescribed form.
The obligation sits in section 5.008 of the Texas Property Code, and the Texas Real Estate Commission publishes the form — currently form 55-1, effective 28 May 2026 — described as covering “material facts and the physical condition of the property.”
We are deliberately not going to tell you which box unpermitted plumbing belongs in, or paraphrase what the form asks. It is a legal document, we could not retrieve its current text, and a confident summary of a form we have not read is exactly the sort of thing this site exists not to publish. Ask your agent or a real estate attorney.
What we can say without any of that: permit records are public, a replaced sewer line or repipe is the kind of thing a buyer’s inspector is trained to spot, and the gap between “we replaced it” and “there is no permit for it” is a question you will be answering at the least convenient moment. Austin’s own warning about refinancing and selling is the city telling you the same thing.
If a licensed company did the work without pulling the permit, understand that you and they are carrying different risks.
Obtaining permits and requesting inspections are among the Responsible Master Plumber’s stated duties — it is part of what the license is for. A company that skips it is not doing you a favor; it is moving a task it owes off its own desk. And the board’s enforcement can reach it: since 1 January 2026 the $4,000 penalty for employing an unlicensed or unregistered individual to perform plumbing is assessed in full, with no reduced settlement.
There is one arrangement worth refusing outright: a contractor who asks you to pull the permit for work they will perform. That moves the responsibility for their work onto you, and it is frequently a sign that the company cannot pull it themselves — because they are not registered with your city, or not licensed at all. Who is legally allowed to touch your pipes covers how to check before you agree to anything.
The situation is recoverable, and it is more common than people think. Three steps, in order:
1. Find out whether a permit exists. Permit records are public. Your city’s building or development services department can tell you what was pulled on your address and when. Sometimes the plumber did pull it and simply never mentioned it.
2. Call the department and ask, before you do anything else. Cities deal with after-the-fact permits routinely. What they will want to know is what was done and when, and they will tell you whether the work can be permitted now, what has to be exposed for inspection, and what it costs. Asking is not a confession; it is how the process starts.
3. Do not open the wall first. Let the city tell you what it needs to see. Guessing wrong means you have opened something for no reason, or closed something they wanted to look at.
If the plumber who did the work is refusing to help, two routes are open to you and they are different. The state board takes complaints about a licensee — TSBPE’s Enforcement Department is on (512) 936-5200, ext. 65249, which is the same line consumers use to check whether valid complaints exist against a license. Your city’s inspection department handles complaints that were never filed with the board; TSBPE’s own guidance tells consumers to “check with your local municipal plumbing inspection department to determine: if any complaints have been filed that were not filed with TSBPE.”
The same facts read differently when the work is someone else’s, and this is the more common situation.
It is a negotiating position, not a disqualification. Unpermitted plumbing is ordinary in Texas housing stock, particularly water heaters. What you are buying is an unknown: nobody independent ever looked at the work. That unknown has a price, and the price is what it would cost to expose, inspect and correct it if it turns out to be wrong.
Three things are worth doing before you decide how much it matters:
Pull the permit history yourself. It is public, it is free, and your city’s building department can tell you what was permitted on that address. A seller saying “the water heater was replaced a few years ago” and the permit record saying nothing are two different pieces of information, and you are entitled to both.
Have the inspector look specifically at it. A general home inspection is not a plumbing inspection. If the disclosure or the permit history points at a repipe, a sewer line or a water heater with no record behind it, say so to your inspector in advance and ask whether a separate plumbing inspection is warranted. On a sewer line, a camera survey answers in an afternoon what no amount of paperwork will.
Ask the city what regularising it would take. Before you agree a price, find out whether the work can be permitted after the fact, what would have to be uncovered, and roughly what that costs. That figure is the one you negotiate with — and it is a real number from the department rather than a guess from either side of the table.
What you should not do is treat the absence of a permit as proof the work is bad. Plenty of unpermitted plumbing is perfectly sound. It is simply unverified, and unverified is a thing you can put a price on.
Skipping the permit saves you a small fee and a scheduling call. It costs you the only independent check that the work was done correctly, and it leaves a gap in the public record of your house that surfaces when you refinance, insure, or sell.
Get the permit. If it is too late for that, call the city — they have heard it before.
