Permit fees are one of the more opaque parts of a plumbing project, mostly because the cost depends on how many fixtures are involved and which jurisdiction issues the permit. In Bellevue the answer is the City of Bellevue, not King County. The city sets its own plumbing fees through its fee ordinance.
The Base Structure
Under Bellevue's fee ordinance that took effect January 1, 2026, a plumbing inspection costs $50.00 for the first fixture and $17.34 for each additional fixture. Both are due when the permit is issued. The ordinance also lists per-pipe fees, including $46 for pipe sizes of one half, three quarter and one inch, $80 for two inch pipe and $126 for four inch pipe.
On top of the inspection fees, each plumbing permit carries an operations fee. The ordinance lists $21 for an over-the-counter permit and $53 for a permit that needs plan review. The city can adjust fees each January 1 for inflation, so the figures can change from year to year.
Permit Fees In Bellevue
Bellevue sets its own plumbing permit fees. The 2026 schedule comes from the city's fee ordinance, which took effect January 1, 2026. The ordinance lists $50.00 for the first fixture, $17.34 for each additional fixture, and operations fees of $21 for over-the-counter permits and $53 for plan review permits.
Public Health Seattle and King County issues its own plumbing permits for Seattle, Clyde Hill and unincorporated King County, and its fee page lists $137 plus $27 per fixture. That schedule does not apply to work inside Bellevue city limits, which is why searching for King County fees can give you the wrong number.

What Counts As A Fixture
Bellevue defines a fixture as any appliance that connects to water, drain or vent. That covers more than sinks and toilets.
- A new or relocated sink, toilet, tub or shower.
- A new floor drain.
- An electric water heater replacement, which needs a plumbing permit.
- A hose bib, dishwasher or other appliance connected to water or drain.
A gas water heater replacement needs a mechanical permit instead of a plumbing permit, so it follows the city's mechanical fee schedule. Altering piping inside a wall, ceiling or beneath a floor is also work the city lists as needing a plumbing permit.
Why This Is Worth Budgeting For, Not Skipping
Unpermitted plumbing work is a common finding during real estate inspections, and it can delay a closing or require retroactive permitting and inspection before a sale proceeds. The permit fee is a small share of most plumbing project costs. Skipping it to save that amount tends to cost considerably more later, either at resale or if something goes wrong with the work.
When we handle a permitted job, the permit fee is built into the quote upfront rather than added as a surprise, and we manage the application and inspection scheduling as part of the work.
How Permit Fees Fit Into A Project Quote
For most plumbing projects the permit fee is small enough that it rarely changes whether a homeowner proceeds. It matters more on projects with many fixtures, such as a remodel or a multi-fixture repipe, where the per-fixture charges add up across the scope of the job.
When we quote a permitted project, the fee appears as its own line item so you can see what goes to the city and what covers labor and materials. That transparency is worth asking for from any contractor if a quote doesn't already break it out.
What To Do If A Fee Looks Wrong
If a permit fee looks higher than expected, the most common explanation is that more fixtures were counted than you anticipated, sometimes because the project grew slightly from the original plan. Review the itemized fixture list against what is actually being installed before assuming an error.
If you still believe there is a calculation error, ask the city's permit staff to review it. A licensed contractor handling your application will usually manage that conversation for you. The city also offers a permit fee estimator that helps you check figures before you apply.
How Permit Timelines Work
Bellevue says plumbing permits that do not require plan review can be issued the same day. That covers many straightforward jobs, such as a water heater replacement. Jobs that need plan review take longer, and the city sets that timeline.
Plan the project around a realistic permit timeline rather than assuming everything moves at over-the-counter speed. If you have a closing deadline, tell your plumber at the very start so scheduling and permit steps can be lined up early. We can't control the city's review time, but early planning helps.
Questions To Ask Before You Approve A Quote
A clear quote tells you which permits the job needs, who applies for them and what each costs. Ask whether the plumbing permit, any mechanical permit and the inspections are all listed. Ask who is present at the inspection and what happens if it does not pass the first time.
Also ask how many fixtures the contractor counted. Bellevue charges a fee for the first fixture and a smaller fee for each additional fixture, so a miscount in either direction changes the total. Comparing two quotes line by line is easier when both show the fixture count.
Finally, ask for a copy of the permit and the final inspection sign-off when the job is done. Keep both with your home records, because a buyer's agent or inspector may ask for them years from now.

Minor repairs such as clearing a clog or swapping a fixture in the same location generally do not. Replacing a water heater does, and so does altering piping inside a wall, ceiling or beneath a floor. Confirm your specific job with the city or your plumber.
The city's fee is based on the work, not on who applies. What differs is whether the fee appears inside a contractor's quote or is paid separately. We list it as its own line item.
The fee ordinance allows the city to adjust fees each January 1 for inflation. The figures here come from the 2026 schedule, so check the current schedule or the city's fee estimator before you budget.
Commercial work often involves plan review, which carries a higher operations fee, and a larger scope. The city can tell you which review path your project needs.
No. Public Health Seattle and King County issues plumbing permits for Seattle, Clyde Hill and unincorporated King County. Bellevue issues its own permits under its own fee ordinance.
