Do You Need a Plumbing Permit for a Bathroom Remodel?
It’s one of the first questions I get on almost every bathroom estimate. The homeowner points across the room and says, “We’re thinking the shower goes over there, and the toilet moves to this wall — do we need a permit for that?”
Short answer: yes. In Florida, the moment you touch the plumbing — move a drain, relocate a water line, add a fixture where there wasn’t one — you’re in permit territory. Swapping a faucet in the same spot is one thing. Cutting into the slab to move a drain is another thing entirely. And I can tell you exactly why the city cares, because I learned the expensive version of that lesson on a real job.
Why the permit isn’t just paperwork
The permit buys you the rough-in inspection. Before a single inch of that pipe gets buried in concrete, an inspector looks at it: the slope on the drain (about a quarter inch per foot — too flat and it clogs, too steep and the water outruns the waste), the venting, the pressure test on the supply lines.
That inspection is the cheapest insurance on the whole job. A drain buried wrong doesn’t announce itself on day one. It announces itself two years later, when somebody’s jackhammering through the brand-new tile you just paid for. The inspector is there to make sure that never happens.
What happens when plumbing gets buried before the inspection
I’m going to tell this one on myself, because it happened to me.
Delray Beach bathroom job. We moved the drains — tub coming out, shower going into a new spot — which meant cutting a trench in the slab, setting new pipe, and patching the concrete back. Somewhere in the shuffle, the inspection sequence got out of order: work that was supposed to be seen got covered before the inspector saw it.
The inspector flagged it. And the city doesn’t shrug at concealed work. I had to bring in an engineer — Troy Bishop, P.E. — to verify the work that was already buried. As I put it at the time: I had to prove my concrete was concrete. Not Twizzlers. Concrete.
It cost me downtime and an engineer’s fee, all over a sequencing mistake anyone could see was a mistake. Lesson learned exactly once: on my jobs, the pipe goes in, the inspector sees it and signs it off, and only then does concrete go back. No exceptions, no shortcuts, no “we’ll catch it at final.”
What usually doesn’t need a permit
Like-for-like fixture swaps — a new faucet where the old one was, a new toilet on the same flange, a new showerhead. Most South Florida cities don’t require a permit for that. But the line is bright: move it, add it, or open the wall or slab to reach it, and you’re pulling a permit.
When in doubt, my rule for homeowners is simple: ask the city before the demo, not after. After is always more expensive.
Who’s allowed to do the work
In Florida, plumbing alterations on a remodel have to be done by a licensed contractor or a licensed plumber working under the permit. A handyman can’t legally pull a plumbing permit here — and if something goes wrong behind your wall, “the handyman did it” is not a sentence you want to say to your insurance company.
My license is CGC1511492. Look it up. Then hire the person whose name is on the permit, because that person is the one on the hook to make it right.
How I handle it on my jobs
I pull the permits. I schedule the inspections. I don’t bury a single pipe before the rough-in is signed off — Delray taught me that lesson once, and once was enough. One contractor, one phone number, the whole job handled: plumbing, tile, electrical, glass, fixtures.

Frequently asked questions
Do I need a permit to replace a toilet or faucet in Florida?
Generally no — like-for-like fixture swaps in the same location don’t trigger a permit in most South Florida cities. Move the fixture, or touch the drain or supply lines in the wall to do it, and you do need one.
What happens if plumbing work is done without a permit?
The city can make you open the work back up for inspection, fail your final inspection, and flag it when you sell. Unpermitted plumbing can also give your insurance company a reason to deny a water-damage claim. The permit is cheap. The fix is not.
Can a handyman move plumbing in my bathroom?
Not legally in Florida — plumbing alterations require a licensed contractor or licensed plumber on the permit. Hire the person whose name is on the permit, because that’s the person accountable for the work.
How much time do plumbing inspections add to a bathroom remodel?
The rough-in inspection itself is a single visit. What costs real time is doing things out of order — I schedule the inspection before the concrete goes back, so the job keeps moving instead of stopping cold.
