Most homeowners don’t think about permits until a contractor mentions them — or until they’re denied a home sale inspection. Here’s exactly when you need a permit for a bathroom remodel in 2026, what happens if you skip it, and how much permits cost.
The short answer: cosmetic work (paint, fixtures in the same location, mirror, hardware) rarely requires a permit. Structural changes, moving plumbing, adding electrical circuits, or altering the layout almost always do.

The Real Cost of Skipping Permits
- Insurance denial: If a plumbing failure causes water damage and the work was unpermitted, your homeowners insurance can deny the claim.
- Home sale problems: Buyers’ inspectors flag unpermitted work. You may need to bring it up to code before closing.
- Fines: Many municipalities fine $200-$2,000 per violation.
- Liability: If unpermitted work injures someone, you bear personal liability.
How the Permit Process Works
- Apply: Your licensed contractor pulls the permit. Homeowners can also pull permits themselves in most states.
- Plan review: For major remodels, the building department reviews drawings. Simple permits are often issued same-day.
- Rough-in inspection: Before walls close, an inspector checks plumbing and electrical rough-in.
- Final inspection: After completion, the inspector signs off with a certificate of completion.
Most licensed plumbers include permit coordination in their service. A contractor who suggests skipping permits is a serious red flag.
Permit FAQs
Can I do the work myself without a permit? In most states, homeowners can pull permits for their own primary residence, but inspections are still required for plumbing and electrical.
What if I already did unpermitted work? Retroactive permits are available in most jurisdictions — an inspector assesses the work and signs off if it meets code.
