Not sure where to start? Take the Bathroom Check.About 2 minutes. Rough answers are fine.Permit rules are local, so the only authoritative answer comes from your city or county building department. What is consistent everywhere is the pattern: cosmetic work usually does not need a permit, and anything that moves plumbing, alters electrical or touches framing usually does.
The usual dividing line
If nothing moves and nothing structural changes, it is normally cosmetic work. Once a drain moves, a circuit is added, or a wall is altered, an inspection usually enters the picture. Some jurisdictions also require one for replacing a tub or shower even in place, because of the waterproofing behind it.
Call the building department and describe the job. It takes one phone call and the answer is free.
Why it should not be in your name
Contractors sometimes ask the homeowner to pull the permit as an "owner-builder". It is faster for them and it moves responsibility for code compliance onto you. If the work fails inspection, or a problem emerges later, that distinction matters a great deal.
This belongs on the quote, which is covered in what a bathroom quote should itemise.
Bottom line
One call to the building department settles it. If a permit is needed, it belongs in the contractor's name and its cost belongs on the quote — see what a bathroom remodel costs.
Common questions
Does replacing a vanity need a permit?
Usually not, if the plumbing stays where it is. Permit requirements are local, so your building department is the authority.
What normally does need one?
Moving plumbing or electrical, altering framing, and often a full gut. Again, this is set locally.
Who should pull the permit?
The contractor. If they ask you to pull it as an owner, you are taking on the code liability for their work.
What happens if work was done without a permit?
It commonly surfaces when you sell or claim on insurance, and resolving it after the fact costs more than the permit would have.
