Bathroom Permit Cost Calculator 2026: What Cities Charge

Permit fees confuse people because there is no national number. Your city sets them, usually as a flat fee per trade or as a percentage of declared project value. The good news: for a typical bathroom, the whole permit package lands between $250 and $1,200, which is one to three percent of the job. Here is how to estimate yours before you call the building department.

When You Actually Need a Permit

• Moving or adding any plumbing fixture — always permitted.
• New or relocated electrical circuits, including a new GFCI or exhaust fan circuit.
• Removing or altering a wall, even a non-structural one in most jurisdictions.
• Converting a tub to a shower, because the drain and pan change.
• Replacing a vanity, toilet or faucet in the same location with no supply changes — usually no permit.
• Paint, mirrors, towel bars, and like-for-like fixture swaps — no permit.

The Fee Model

Most cities use one of two methods. Trade-based cities charge a flat fee per discipline. Valuation-based cities charge a base fee plus a rate per thousand dollars of declared project value, typically $8-$18 per $1,000.

Typical 2026 Trade Fees

• Building or general permit: $90-$350
• Plumbing permit: $70-$250
• Electrical permit: $60-$220
• Mechanical (exhaust ventilation): $50-$150
• Plan review, when required: $75-$300 or 25-65% of the building fee
• Re-inspection after a failure: $50-$150 each

Estimate by City Size

• Small town or rural county: $150-$400 total
• Mid-size city or suburb: $350-$700 total
• Large metro: $600-$1,200 total
• Coastal California, Seattle, Boston, NYC: $900-$2,000+, often with plan review
• Historic district or condo building: add $200-$800 for review and building approvals

Ask the contractor whether permit fees are in the bid or billed as a pass-through. It is a small number, but a surprise small number tells you how the rest of the bid was written.

How to Estimate Yours in Ten Minutes

1. Search your city name plus 'building permit fee schedule' — nearly every jurisdiction posts a PDF.
2. Find whether fees are flat per trade or based on valuation.
3. If valuation-based, use your contractor's contract price as declared value; understating it is fraud and voids the permit.
4. Add every trade you are touching: building, plumbing, electrical, mechanical.
5. Add plan review if you are moving a wall or fixture.
6. Add one re-inspection fee as your own contingency.

What Unpermitted Work Really Costs

• Retroactive permits, typically at double or triple the original fee.
• Opening finished walls so an inspector can see the rough-in — demo and repair on your dime.
• Insurance claims denied when a leak traces back to unpermitted plumbing.
• Buyers demanding a price reduction or escrow holdback at resale.
• Appraisal excluding the improved square footage from value.

Frequently Asked Questions

How much does a bathroom remodel permit cost?

Most homeowners pay $250-$1,200 total across building, plumbing and electrical permits. Large coastal metros with plan review run higher.

Do I need a permit to remodel a bathroom?

Yes if you move plumbing, add electrical circuits, or alter walls. No for cosmetic work such as paint, a mirror, or swapping a vanity in the same position.

Who pulls the permit, me or the contractor?

Let the licensed contractor pull it. If you pull it as an owner-builder, you become responsible for code compliance and for any inspection failure.

What happens if I remodel without a permit?

Fines, retroactive permits at a penalty rate, forced demolition of finished surfaces for inspection, and disclosure problems when you sell.

Do I need a permit to replace a toilet or vanity?

Usually not, as long as the fixture stays in the same location and the supply and drain lines are unchanged.
