Serving Santa Ana & Central OC
Plumbing work that is regulated by code needs a permit from the City of Santa Ana. Your contractor should pull it, it should appear on your quote as its own line, and the finished work should be inspected. A contractor who offers to skip it is offering you a small saving in exchange for an unpermitted alteration on your property record.
The principle is straightforward: work that alters the plumbing system is permitted, and work that swaps a component like for like usually is not. Confirm your specific job with the City rather than relying on any general list, including this one.
| Work | Typically |
|---|---|
| Whole-house repipe | Permit |
| Replacing a section of buried water line | Permit |
| Sewer lateral repair or replacement | Permit |
| Water heater replacement | Permit, handled as a same-day express permit |
| Rerouting a supply line | Permit |
| Adding or relocating a fixture | Permit |
| Replacing a tap or a fixture in place | Usually not |
| Clearing a drain | No |
That third point is the one to be alert to. There are legitimate owner-builder situations, but a licensed contractor asking the homeowner to take on the permit for their work is shifting liability, and it is worth asking why directly.
| With a permit | Without |
|---|---|
| The work is on the property record | It is not, and a buyer’s agent will notice |
| An inspector signed it off | Nobody did |
| It supports the value of the improvement | It can become a negotiating point against you |
| A warranty claim has documentation behind it | Harder to substantiate |
| An insurance claim has it too | One more thing to argue about |
| Nothing to disclose awkwardly | Unpermitted work is generally disclosable |
A repipe is one of the more valuable things you can tell a buyer about an older house. Unpermitted, it stops being a selling point and becomes a question, which is a poor return on whatever the permit would have cost.
The accessible-for-inspection step is the practical one to watch. It is also why a repipe timeline has a pause in it, and why a schedule that closes walls immediately after the pipework is worth a question.
It is easy to read all of this as bureaucracy with a fee attached. The reason it exists is more specific than that, and it is worth understanding because it explains which jobs are permitted and which are not.
| What inspection checks | Why it matters to you |
|---|---|
| Materials are approved for the use | Not everything sold is rated for potable supply |
| Connections are made correctly | The joints you will never see again |
| The system was pressure tested | A repipe that was not tested is not finished |
| Backflow protection where required | Keeps non-potable water out of your drinking supply |
| Drain slope and venting | A drain that does not vent properly never works right |
| Nothing structural was compromised | Notching a joist to route a pipe has limits |
Every row on that list is something you cannot check yourself once the walls are closed, and something a bad job would look identical to a good one without. That is the whole argument, the permit is not verifying that the water comes out of the tap. It is verifying the parts of the work that become invisible five minutes after it is finished.
Being straight about the limits of this page is more useful than filling it with numbers we cannot stand behind.
The Permit Counter answers all four of those directly on (714) 647-5800, and they answer them for your address and your job rather than in general.
Our position is simple: we will not close walls over unpermitted work we did, and we will not tell you somebody else’s unpermitted work is fine because it looks fine.
We are licensed and insured plumbers, and this site is about leaks, finding the ones you cannot see and repairing them properly. Roughly half of what looks like a plumbing leak turns out not to be one, so the boundary is worth stating plainly.
Roof leaks are a roofer. Water under an air handler is an HVAC technician clearing a condensate drain. Water under an appliance is appliance repair. Drying, restoration and mold are separate trades again, and gas line repair is SoCalGas or a licensed gas fitter. We detect gas leaks, we do not repair gas lines.
The full list, with the trade to call for each, is on what we don’t do.
If a job genuinely does not need one, the quote says that too rather than staying silent about it.
Detection itself needs no permit — nothing is being altered. It becomes relevant at the repair stage, and it is on the written quote before you agree to anything. The repipe process, including where the inspection sits in the schedule, is on how to repipe a house.
Permits appear as their own line on our quotes, pulled by us where they apply.

Swapping a tap in place usually does not. Confirm your specific job with the City on (714) 647-5800.
Your licensed contractor, and on our jobs we do. It is our licence attached to the work. A contractor asking you to pull the permit for work they are doing is shifting liability, and it is worth asking why.
We do not publish a figure, because fees change and vary by job and a wrong number on a web page is worse than none. The Permit Counter gives you the actual figure for your job on (714) 647-5800.
Water heater replacement and on-site sewer work are handled as same-day express permits, so the paperwork is not a reason for those to wait. For anything else, ask the City rather than relying on a general answer.
The work is left accessible — walls are not closed over new pipework — and an inspector either signs it off or lists corrections. Corrections are made and re-inspected, then the permit is finalled. Keep a copy of that.
Yes. A permitted repipe is a selling point on an older house; the same work unpermitted becomes a question and often a negotiating point against you. It is generally disclosable too.
Retroactive permitting exists, and it typically means opening up to allow inspection, which is exactly why it is a worse process than doing it in order. Start with the City rather than assuming either way.
It might be, and it is not our determination to make about somebody else’s work. Call the City and describe the job. It is a free phone call and it settles it definitively.
No. Nothing is being altered — detection is diagnostic. It becomes relevant at the repair stage, and where one applies it is on the written quote before you agree to anything.
A homeowner can pull an owner-builder permit for work on their own property, and it carries real responsibilities — read what you are signing. For work a licensed contractor is performing, they should be pulling it.
