Does a bathroom remodel need a permit in Columbus?
The honest answer is that it depends on two things: what is actually being changed, and which building department your address answers to. Central Ohio is not one jurisdiction. Columbus, the suburbs around it and the townships between them each run their own building departments with their own requirements, so a confident single answer to this question would be wrong for somebody reading it. Which code governs the plumbing in an Ohio house, who holds the state plumbing license, and which office inspects in each Central Ohio county are set out on the code and license page. How Ohio's state building code came to cover houses at all, after decades of leaving them out, is on the page on who shaped Central Ohio houses.

The distinction that usually decides it
Across jurisdictions the same general line tends to apply, even where the details differ. Replacing a fixture with a similar fixture in the same location is treated as one kind of work. Moving plumbing, altering or adding electrical circuits, changing ventilation, or touching anything structural is treated as another, and it is the second kind that generally brings a permit and an inspection into it.
That is a rule of thumb for orienting yourself, not a ruling on your project. Some departments take a broader view than others, and the only answer that counts for your house is the one your own building department gives.
Why we will not tell you your answer
We would rather be useful than confident. Publishing a specific claim about what Columbus, or Westerville, or Delaware County requires would put a sentence on the internet that goes out of date without anybody noticing and that was never true for half the people reading it anyway.
What we can tell you is where the answer lives: the building department for the jurisdiction the property actually sits in. Which is worth checking rather than assuming, because a mailing address is not the same as a jurisdiction. A great many Powell addresses are in a Delaware County township, some Gahanna addresses are in Jefferson or Mifflin Township, and Westerville, Dublin and New Albany each straddle a county line. Which jurisdictions are certified to enforce the residential code today, county by county and suburb by suburb, is set out on the page about which building code a house was built under.
Who should pull it
Where a permit is required, the contractor performing the work normally obtains it. What matters more than the convention is that the answer is written down before you sign, because this is a question with a bad failure mode: everyone assumes the other party is handling it and nobody does.
So get it in writing, on any bid from anyone: whether the work requires a permit, who applies for it, who pays the fee, and who meets the inspector. Four short answers, and they cost nothing to ask for.
Be wary of being asked to pull it yourself. A homeowner can obtain a permit on their own property in many jurisdictions, and there are legitimate reasons for it. But a contractor who asks you to do it because it is simpler is asking you to carry the responsibility for the work, and that is worth understanding before you agree rather than after.
What an inspection actually is
An inspection is somebody from the building department looking at specified stages of the work before they are covered up. On a bathroom that usually means the rough-in stage, when the plumbing and any electrical are in place but the walls are still open, and a final look once everything is finished. What the adopted electrical code asks of a bathroom, and which office inspects the wiring in each Central Ohio county, is on the bathroom electrical page. How the City of Columbus came to inspect what is built, office by office, is on the page on how Columbus came to inspect its houses.
It is not an adversarial process and it is not a judgment on your taste. The inspector is checking that what was installed matches what was permitted and meets the code the jurisdiction has adopted.
Does it slow the job down?
It affects the calendar more than it affects the days on site. An inspection has to be scheduled and the work cannot be closed up until it has happened, so it introduces a dependency the schedule has to plan around rather than a delay in the ordinary sense.
For a straightforward conversion that keeps the plumbing where it is, this often does not arise at all. For a project that moves fixtures, it is part of the plan from the start and belongs on the projected schedule you are given before work begins.
Work the previous owner did without one
This turns up more often than people expect, usually when a wall comes open and what is behind it does not match how the house is documented. It is not a catastrophe and it is usually not anybody's fault who still lives there.
What matters is what happens next: unpermitted work that is unsafe should be corrected, and unpermitted work that is merely undocumented is a question for your building department rather than for a contractor to rule on. Either way it belongs in the same category as any other hidden condition, which means you see it, you get a price, and you decide.
Common questions
Does a bathroom remodel need a permit in Columbus, Ohio?
It depends on what is being changed and on which building department your address answers to, and Central Ohio is not one jurisdiction. The general line, which holds fairly widely even where details differ, is that replacing a fixture with a similar one in the same place is treated differently from moving plumbing, altering electrical, changing ventilation or touching structure. The second kind is what generally brings a permit and an inspection into it. Your own building department gives the answer that counts.
Does a tub-to-shower conversion need a permit?
Often it raises fewer questions than a full remodel does, because a conversion that keeps the drain and the valve where they already are is changing a fixture rather than relocating plumbing. Once a project starts moving the drain, altering circuits or changing anything structural it is a different conversation. As with everything on this page, the jurisdiction your property sits in decides, not a website.
Who is responsible for pulling the permit?
Where one is required the contractor doing the work normally obtains it, but the important thing is that it is written down before you sign rather than left to convention. This question has a bad failure mode where both parties assume the other is handling it. Ask any bidder for four answers in writing: whether it needs a permit, who applies, who pays the fee, and who meets the inspector.
Do the suburbs issue their own permits?
Yes, and that is why a single answer to the permit question does not exist here. Columbus, the suburbs and the townships between them run their own building departments. It is also worth confirming which jurisdiction your property is actually in rather than going by the mailing address, since many Powell addresses are in a Delaware County township, some Gahanna addresses are in a township, and Westerville, Dublin and New Albany each straddle a county line.
Does a permit slow the project down?
It affects the calendar more than the days on site. An inspection has to be scheduled and the work cannot be closed up before it happens, so it becomes a dependency the schedule plans around rather than a delay in the ordinary sense. For a conversion that leaves the plumbing where it is, it often does not arise. Where it does, it belongs on the projected schedule you are given before work starts.
What if the previous owner did work without a permit?
It turns up more often than people expect, usually when a wall comes open and what is behind it does not match how the house is documented. Unpermitted work that is unsafe should be corrected. Unpermitted work that is merely undocumented is a question for your building department rather than something a contractor should rule on. Either way it is a hidden condition like any other, which means you see it, you get a price and you decide.
