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 and most of the suburbs run their own building departments, most townships send residential permits to their county's department, and each sets its 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
Some departments draw a line like this one, and others do not. 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 take a much broader view: the City of Columbus's own list of typical residential projects puts every kitchen or bath remodel under "requires a permit and plan review". In most of Central Ohio the plumbing permit comes from the county health department rather than the building department, so ask both.
Where your answer lives
Each office publishes its own rules and changes them, so this page points to the office rather than restating it. For the City of Columbus, the Building and Zoning Services sheet "Typical Residential Projects" (revised March 2026) lists a kitchen or bath remodel as requiring a permit and plan review.
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 for work on a home they live in, 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. What the City of Columbus's own building and housing codes asked of a dwelling between 1919 and 1986 is on the page on the Columbus building and housing codes.
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.
Where a permit is required, the inspection belongs on the schedule from the start.
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. Some departments treat replacing a fixture with a similar one in the same place differently from moving plumbing, altering electrical, changing ventilation or touching structure, and others do not: the City of Columbus lists every kitchen or bath remodel as requiring a permit and plan review. Your own building department and, for plumbing, usually your county health department give the answers that count.
Does a tub-to-shower conversion need a permit?
It can, and in the City of Columbus a bath remodel requires a permit and plan review. Even where the building department treats a conversion that keeps the drain and valve in place as a fixture change, the county health department may still require a plumbing permit to set a new shower. 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 and most suburbs run their own building departments, and most townships send residential permits to their county's department. 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. Where a permit is required, the inspection belongs on the schedule from the start.
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.
