When a Bathroom Remodel in NJ Requires a Permit

Under the New Jersey Uniform Construction Code (UCC), permits are required for any work that affects plumbing, electrical systems, structure, or occupancy.

When You Don’t Need a Permit

Some projects are considered “ordinary maintenance” and don’t require permits. You typically won’t need one if you are:

• Painting, wallpapering, or replacing tile

• Swapping plumbing fixtures without moving water lines

• Replacing a vanity with the same size and plumbing setup

• Installing new flooring

⚠ Important: Always check with your local building department before assuming your work is permit-free. Some municipalities in NJ have stricter requirements.
