Kansas City, MO
Kansas City, Missouri plumbing permit cost
A Kansas City plumbing permit is the same valuation ladder read against the plumbing valuation — $1–$50,000 flat table, then $686 + $12.50 / $2,561 + $8.30 / $9,201 + $3.60 per $1,000 or fraction, per building, plan review credited at one-half.
How this fee is calculated
These are the components the schedule defines for this permit, as they applied on 2026-09-28. A component only applies to your project if its conditions match — read that column before assuming a figure. Want a figure for your own project? Estimate this fee with the permit fee calculator.

A real permit fee is these components added together. The department’s final calculation is the one that applies — this is the schedule it will be based on.
A worked example
Follow the arithmetic by hand. Every line is produced by the engine from the rules above, so the total cannot drift away from the schedule behind it.

Fees that do not apply here
Listed so you can see what was considered and left out, rather than wondering whether something is missing. A rule can also be left out because it is not published for this permit at all, and that is stated where it matters.
- Plumbing permit — $1,000,001 and over: $9,201.00 plus $3.60 per $1,000 or fraction above $1,000,000 — This fee does not apply to the inputs provided.
- Plumbing permit — $200,001 to $1,000,000: $2,561.00 plus $8.30 per $1,000 or fraction above $200,000 — This fee does not apply to the inputs provided.
- Plumbing permit — $50,001 to $200,000: $686.00 plus $12.50 per $1,000 or fraction above $50,000 — This fee does not apply to the inputs provided.
Assumptions
- Calculated from 1 fee rule in effect on 2026-09-28.
- Amounts are rounded to the nearest cent, once, at the end of each component.
$15,000 has not left the flat table: it falls in $15,001–16,000 $261.00? No — $14,001–15,000 $248.50, $15,001–16,000 $261.00 — so $15,000 is $248.50 (the row strictly enclosing it). Put the same value one dollar higher at $15,001 and it pays $261.00 (the next $1,000 row). $50,100 pays $698.50 in the first band above the table; $250,000 pays $2,561.00 + $8.30 × 50 = $2,976.00; $2,000,000 pays $12,801.00 — each trade by trade, each building by building.
$300 valuation pays $48.00 — still inside the opening flat row. The ladder's $77 partial-minimum and $50 supplemental minimum are floors on partial/supplemental permits as instruments, not on this row's own $48 floor — dividing a job into partials costs more than one permit, by the sheet's own sentence.
What is different in Kansas City
Plumbing reads the same sheet, because the sheet is not a building sheet: its title already covers Building, Mechanical, Plumbing, Electrical, Elevator and Fire Protection together. $1,500 of plumbing valuation pays $86.00 (the $501–2,000 row); $15,000 pays $261.00 (the $15,001–16,000 row); $50,100 pays $686.00 + $12.50 = $698.50; $250,000 pays $2,561.00 + $8.30 × 50 = $2,976.00; $2,000,000 pays $12,801.00 — each reproducing the commercial ladder at the plumbing valuation.
Residential plumbing in a building of three or more dwelling units is explicitly on this ladder — the subtitle's 'INCLUDING RESIDENTIAL BUILDINGS WITH THREE OR MORE DWELLING UNITS' — while residential plumbing in a building of one or two dwelling units is not covered by any sheet readable from this sandbox and is therefore not modelled here. The credited-prepayment and ancillary block are identical to the building and electrical permits: one-half credited, changes $50, partial $77, supplemental $50, resubmittal 1/8 capped at $272, express $69.
What this figure does not include
Impact fees, utility connections and other departments’ permits are the usual omissions, and in some jurisdictions they are larger than the permit fee itself.
Not included in these figures
This is the plumbing permit fee read from the commercial schedule at the plumbing valuation. It excludes residential plumbing in a building of one or two dwelling units (no sheet readable), any second-charged plan-review half-fee, and any separate trade schedule beyond naming this ladder.
Common questions
How much is a plumbing permit in Kansas City?
The same four-rule ladder read against the plumbing valuation: $1–500 $48 … $49,001–50,000 $686.00 flat; $50,001–$200,000 at $686 + $12.50; $200,001–$1,000,000 at $2,561 + $8.30; $1,000,001+ at $9,201 + $3.60 per $1,000 or fraction. $15,000 of plumbing valuation is $248.50; $250,000 is $2,976.00.
Does residential plumbing use a different schedule?
Residential buildings of three or more dwelling units do not: the sheet's subtitle already says 'INCLUDING RESIDENTIAL BUILDINGS WITH THREE OR MORE DWELLING UNITS'. Residential plumbing in a building of one or two dwelling units has no Kansas City schedule readable from this sandbox, so no such amount is modelled.
Is plumbing plan review a separate charge?
No — the same credited prepayment as every other trade: one-half of the permit cost paid at plan submission, credited at issuance. Changes $50, partial-minimum $77, supplemental $50, resubmittal capped at $272, express $69 — all flat rows beside it.
How finely does the plumbing permit price?
One flat amount per $1,000 window to $50,000; then $12.50 per $1,000 or fraction to $200,000 and $8.30 / $3.60 above — so $50,100 buys one more whole $12.50, and $200,100 buys one more whole $8.30. The ladder is per building, so doubling the buildings doubles the filings.
